Memory rehabilitation in Alzheimer's disease: a review of progress.

BACKGROUND: Memory rehabilitation is a sadly misrepresented area of applied research in Alzheimer's disease. OBJECTIVES: To gather and evaluate recent evidence for the clinical effectiveness or ecologically validity of memory rehabilitation for mild to moderate Alzheimer's patients. METHODS: Computerised searches and some handsearching were conducted spanning the last five years, from 1995 to 2000, inclusively. Criteria for inclusion in this overview involved the use of a precise memory rehabilitation technique within an experimental study design applied to Alzheimer's patients with pre- and post-treatment evaluation. FINDINGS: Three potential levels of memory rehabilitation procedures with proven clinical or pragmatic efficacy were identified. The first level bears on the facilitation of residual explicit memory with structured support both at encoding and at subsequent recall; the second level of memory rehabilitation exploits the relatively intact implicit memory system (priming and procedural memory); the last deals with finding ways of coping with the patient's limited explicit memory capacities through the use of external memory aids. A proposal of suggestions for good practice and future research in memory rehabilitation is also offered with the hope to spur further development in this rapidly expanding area of applied research. CONCLUSION: The available evidence shows that alternative and innovative ways of memory rehabilitation for Alzheimer's patients can indeed be clinically effective or pragmatically useful with a great potential for use within the new culture of a more graded and proactive type of Alzheimer's disease care.

Neurological and social long-term outcome after early rehabilitation following traumatic brain injury. 5-year report on 240 TBI patients.

The long term courses of patients after traumatic brain injury (TBI) are particularly influenced by the quality of neuropsychological rehabilitation and social reintegration. Though we do have data from different European countries about the success of surgery and intensive care, we don't know much about the long term courses, mirrored by the patients, their relatives and local physicians in their domestic environment. Supported by a pilot project of the government of Nordrhein--Westfalia we reviewed 252 patients with different grades of TBI, which were treated in our department from emergency to the end of early rehabilitation. At least 240 files could be completed, including observations up to 5 years after trauma (mean 26 months). 66% of the patients suffered from severe TBI according to the initial Glasgow Coma Scale (GCS), 23% showed moderate and 11% mild TBI. After discharge from early rehabilitation and during further treatment in rehabilitation hospitals patients with persistent vegetative state (PVS) did not show a significant benefit from therapy: Only 1 patient improved to GOS 3, fatal courses were observed in 3 patients, 11 patients remained unchanged. Patients with GOS 3 at the end of early rehabilitation on the other hand could improve in 51 cases to GOS 4 and 5. At the time of the actual investigation 32% of the patients reached GOS 5, 27% GOS 4. Unfavourable courses showed 21% (GOS 3), 5% (GOS 2) and 15% (GOS 1). Referred to the initial GCS only 16% of the severe, 27% of the moderate and 33% of the mild TBI could return to their former social activities and profession without any cuts. 145 of the total of surviving patients could return to their families, in the group of vegetative patients all except 1 patient were submitted for nursing homes. Only 58% of the patients practiced any kind of outpatient rehabilitation, a specialized neuropsychological training has been restricted to 7% of the patients. So we observe a significant gap between a high impact clinical medicine on one side and a deficient outpatient treatment on the other. At least many patients are standing alone after discharge from rehabilitation hospitals, resulting in prolonged stationary treatment with extensive costs to minimize damage from this situation. Our consequence for a more efficient treatment is, that we substantially need better programs by local administrations, insurance companies and employers for better and earlier reintegration to avoid isolation and unnecessary invalidation, especially of those patients with the best medical prognosis.

[Health promotion and inpatient rehabilitation. Long-term effects of education in patients with coronary heart disease].

BACKGROUND AND PURPOSE: The most important goals in the rehabilitation of patients with a coronary heart disease (CHD) include the diagnosis and treatment of risk factors, health promotion, and education. The knowledge on and awareness of cardiovascular risk factors is an important precondition for a high patient compliance. Former studies on patients in cardiologic departments of hospitals showed no effect of health promotion and education on patients' knowledge on risk factors, presumably because of the setting in acute therapy. Therefore, the possible effects of health promotion and education on the knowledge of patients were studied in the setting of an inpatient rehabilitation. METHODS: Over 1 year, 426 patients, admitted to an inhospital rehabilitation, were questioned on the first and last day of their stay using a validated instrument ("Bochumer Bewertungsbogen-Kardiovaskuläre Risikofaktoren" [BBKR], Table 1). 1 year after discharge, the same questionnaire was sent to the surviving 423 patients. Of these, 267 patients (63.1%) answered. The average age was 64.3 years (standard deviation [SD] 11.3). Demographic data and clinical history are summarized in Table 2. RESULTS: For most of the known risk factors of CHD, the number of patients mentioning them significantly increased during the observation period. On the day of admittance, only 59.2% mentioned diabetes mellitus as a risk factor compared to 74.6% 1 year after discharge. Especially patients with a CHD improved their knowledge on their disease (Figure 1). Education and number of rehabilitations in the past had an influence on the knowledge of interviewed patients on the day of admittance. Especially elderly patients had an increase in knowledge, indicated by a higher score in the questionnaire (Table 3). Participation in patients' self-help meetings within the observation time had no influence on the knowledge. Patients with known hypertension or hyperlipoproteinemia and overweight patients could increase knowledge on the cardiovascular risk of their disease (Figure 2). CONCLUSION: The results of this query document the lack of knowledge on cardiovascular risk factors of patients before rehabilitation. Especially the results of patients with a diagnosed (and treated) CHD after an inpatient stay in an acute hospital in the past were surprising. The stationary rehabilitation is an appropriate measure to improve this knowledge. It can be used for secondary prevention. The raise in knowledge was evident 1 year after discharge; a long-term effect of health education during stationary rehabilitation is likely.

[The North American Spine Society Lumbar Spine Outcome Assessment Instrument: translation and psychometric analysis of the German version in rehabilitation patients with chronic back pain].

The "Lumbar Spine Outcome Assessment Instrument", developed by the North American Spine Society (NASS), was translated into German. Its psychometric properties were tested in a group of rehabilitation patients with chronic, unspecific back pain, and in a comparison group of patients in cardiologic rehabilitation. With a Cronbach's alpha of 0.92, internal consistency was high. Principal component analysis revealed that the German version of the NASS instrument surveys the factors "back pain", "neurologic symptoms", and "impairments". A strong correlation with other measures of functional impairment (FFbH-R, IRES) indicates a high concurrent validity of the NASS instrument. After three weeks of inpatient rehabilitation, sensitivity to change could be demonstrated for the summary score of the instrument. This significant change was primarily due to moderate effects in the factor "back pain". In our study population, the factor "impairments" did not show a significant change. On the basis of these results, the German version of "The North American Spine Society Lumbar Spine Outcome Assessment Instrument" can be described as a reliable and valid instrument for measuring back pain, related neurologic symptoms, and back pain-induced impairments in rehabilitation patients. Because the factor "impairments" is not sensitive to change within three weeks of rehabilitation, the instrument is only partly suitable for measuring short-term outcome in rehabilitation patients. Further research is needed to determine if the instrument is useful for middle- and long-term outcome measurement in rehabilitation.

Economic evaluation of a community-based pulmonary rehabilitation program for chronic obstructive pulmonary disease.

Pulmonary rehabilitation has been demonstrated to be efficacious in chronic obstructive pulmonary disease (COPD), however, its cost-effectiveness is largely unknown. The present study determined the cost-effectiveness of a community-based pulmonary rehabilitation program for COPD patients with mild, moderate, and severe disease. We compared the direct costs (in Canadian dollars) and disease-specific quality of life (measured by the St. George's Respiratory Questionnaire, SGRQ) of patients with COPD (N = 210) who enrolled in the rehabilitation program in Edmonton, Canada one year before and after completion of the program. To determine temporal trends in health service utilization between 2000 and 2002 we used similar data from 592 COPD patients from the same region who did not participate in the rehabilitation program. We found that the health status of patients enrolled in the program improved significantly following pulmonary rehabilitation, irrespective of the severity of disease (total SGRQ score improved by 4.85%, p = 0.001). The total direct cost per 100 person-years of follow-up before the program was $122,071 (SE = 29,566); after the program it was $87,704 (SE = 26,146). The average reduction of total costs before and after the program was $34,367 per 100 person-years or approximately $344 per person per year (p = 0.02). Over one-year, pulmonary rehabilitation was associated with decreased health service utilization, reduced direct costs and improved health status of COPD patients. This suggests that pulmonary rehabilitation is cost-effective for patients with relatively high utilization of emergency and hospital-based services.

Influence of a rehabilitation sports programme on the fibrinolytic activity of patients after myocardial infarction.

The influence of regular physical exercise on fibrinolysis was studied in two groups of patients after myocardial infarction. The two groups were of similar age and living habits. One of the groups took part in a rehabilitative training programme while the other group did not participate in any sports activities. Several fibrinolytic variables, including plasminogen activator inhibitor (PAI) activity and PAI-1 antigen, were studied before and after an ergometric test performed at three different times: at the end of hospitalization (before beginning the rehabilitation programme), three months and six months after myocardial infarction. Our results indicate that by the sixth month fibrinolytic activity, measured by the tissue plasminogen activator (t-PA) capacity, had decreased significantly (p less than 0.025) in the patients who were not participating in the rehabilitation programme whereas it had increased slightly in the patients involved in the rehabilitation programme in comparison with the initial values. It was also observed that while PAI activity remained constant or decreased slightly in patients after six months in the rehabilitative sports programme, these PAI levels increased significantly in patients who were not in the sports programme. Our results indicate that there was a significant decrease in the fibrinolytic capacity of patients who were not participating in the rehabilitation sports programme, while the patients involved in the rehabilitation programme showed a slight improvement in their fibrinolytic activity.

Clinical profile and outcomes of diabetic and nondiabetic patients in cardiac rehabilitation.

BACKGROUND: Patients with diabetes mellitus have increased risk of cardiovascular disease; however, there are limited data addressing cardiac rehabilitation in these patients. This study assessed the effectiveness of participation in cardiac rehabilitation on clinical outcomes after myocardial infarction and/or revascularization procedures in diabetic and nondiabetic patients. METHODS: Analysis on 1505 patients completing a minimum of 7 weeks of a 12-week cardiac rehabilitation program included fasting lipid profile and glucose, body mass index, and metabolic equivalent time in patients with diabetes (n = 292) and without diabetes (n = 1213). RESULTS: There were significant improvements in total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) in each group after cardiac rehabilitation. Diabetic women and nondiabetic men had the greatest improvement in HDL-C, with an improvement of 4.9% in diabetic women (P = .02) and an improvement of 4.1% in nondiabetic men (P < or = .0001). On completion of cardiac rehabilitation, both diabetic and nondiabetic patients were at National Cholesterol Education Program Adult Treatment Panel III goals in total cholesterol, LDL-C, HDL-C, and triglycerides at a higher rate. However, patients with diabetes did not reach National Cholesterol Education Program goals for HDL-C, total cholesterol, and triglycerides as effectively as nondiabetic patients. Exercise capacity improved by 28.1% in diabetic patients after cardiac rehabilitation (P < .0001). Improvement in outcomes in the patients with diabetes occurred without significant change in body mass index. CONCLUSIONS: These results suggest that participation in a comprehensive cardiac rehabilitation program integrates care of patients with chronic conditions such as diabetes to achieve comparable cardiac risk factor reduction as achieved with nondiabetic patients.

Do preinjury alcohol problems predict poorer rehabilitation progress in persons with spinal cord injury?

OBJECTIVE: To determine whether a history of alcohol-related problems is associated with inpatient rehabilitation progress. DESIGN: Cross-sectional cohort survey. SETTING: Acute inpatient rehabilitation program in a level I trauma center. PARTICIPANTS: Seventy-six of 104 consecutive patients with spinal cord injury (SCI) who met inclusion criteria and had completed interviews and functional outcome data. Participants were on average 38 years old; 84% were white, and 86% were men. Forty-two percent had tetraplegia and 39% had a history of problem drinking. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM instrument admission, discharge, and efficiency scores as well as rehabilitation length of stay (LOS). RESULTS: The group with a history of problem drinking had significantly lower FIM admission, discharge, and efficiency scores and longer rehabilitation LOS. After controlling for potential confounding factors, a history of problem drinking accounted for a significant proportion of the variance in FIM efficiency scores. CONCLUSIONS: A history of problem drinking may be a risk factor for poorer rehabilitation progress among patients with SCI. They may be more costly to rehabilitate and may be discharged before attaining an adequate level of independence. Despite this, the current rehabilitation prospective payment system does not recognize this common comorbid condition.

Rehabilitation of children with traumatic brain injury: descriptive analysis of a nationwide sample using the WeeFIM.

OBJECTIVE: To describe functional capability at admission and discharge of children with traumatic brain injury (TBI) in rehabilitation settings. DESIGN: Descriptive analysis. SETTING: Inpatient pediatric rehabilitation hospitals in the United States. PARTICIPANTS: Children (N=3815) in 56 pediatric inpatient rehabilitation facilities who were discharged during 1999 to 2001. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Admission and discharge WeeFIM scores. RESULTS: Admission and discharge WeeFIM scores correlated positively with age at admission, time from injury to rehabilitation admission, and length of stay (LOS). Higher admission WeeFIM scores correlated with shorter LOS, shorter time from injury to admission to rehabilitation, and higher discharge WeeFIM scores. CONCLUSIONS: Children with TBI demonstrated significant improvement in functional measures during rehabilitation. Discharge function and LOS correlated with admission severity, with children who had higher functional status and shorter time between injury and rehabilitation care having higher discharge function and shorter LOS.

Inpatient rehabilitation following burn injury: patient demographics and functional outcomes.

OBJECTIVE: To identify demographic characteristics of burn patients referred for inpatient rehabilitation, the benefits of rehabilitation in this population, and factors that influence functional outcome. DESIGN: Retrospective chart review. SETTING: Free-standing rehabilitation hospital. PARTICIPANTS: Patients (N=129) admitted for inpatient rehabilitation after a burn injury. INTERVENTION: Comprehensive inpatient rehabilitation. MAIN OUTCOME MEASURES: Demographic data and the FIM instrument on admission and discharge for all patients. RESULTS: Linear measures of functional status derived by Rasch analysis of the FIM showed significant improvements from admission to discharge for all patients. There was no correlation between total body surface area (TBSA), premorbid psychiatric alcohol or drug abuse history, and change between admission and discharge FIM score. There was a significant correlation between TBSA burn and age and between TBSA and length of stay. CONCLUSIONS: Burn patients referred for inpatient rehabilitation are either older or have large TBSA burns. All patients made significant functional improvements and consequently inpatient rehabilitation can be considered an important component of care after a burn injury.

Inpatient rehabilitation outcome after hip fracture surgery in elderly patients: a prospective cohort study of 946 patients.

OBJECTIVE: To identify the factors associated with inpatient rehabilitation outcome after surgical repair of hip fracture in elderly patients. DESIGN: A noninterventional prospective cohort study. SETTING: Geriatric inpatient rehabilitation center in a tertiary university medical center in southern Israel. PARTICIPANTS: Patients (N=946) aged 65 years of age or older who were hospitalized for rehabilitation after surgery for hip fracture. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Functional studies by the FIM instrument and a broad spectrum of clinical, demographic, and social variables. Stepwise multiple regression was used to assess the relative contribution of the variables to the variance of the percentage change in the FIM score during the course of rehabilitation in relation to the severity of the functional impairment at its inception. RESULTS: Eight variables were significantly and independently associated with rehabilitation outcome. Prefracture FIM scale (standardized regression coefficient in multiple regression [beta]=.261, P<.001), serum albumin at discharge (beta=.222, P<.001), Folstein Mini-Mental State Examination (beta=.174, P<.001), visual impairment (beta=-.089, P=.002), dyspnea at mild exertion (New York Heart Association class III) (beta=-.080, P=.005), age (beta=-.080, P=.007), poststroke motor impairment (beta=-.072, P=.011), and decreased serum folic acid (beta=-.055, P=.047). The total percentage of the explained variance of the primary rehabilitation outcome measure accounted for by these 8 variables (adjusted R(2)) was 31.9%. CONCLUSIONS: The outcome of rehabilitation of elderly patients after surgical repair of hip fracture is associated with 4 clinical and nutritional correctable parameters. The other 4 variables that are associated with the process cannot be corrected but may help predict outcomes and adjust expectations.

Cardiac rehabilitation reduces the rate of major adverse cardiac events after percutaneous coronary intervention.

BACKGROUND: Despite multiple publications on effects of rehabilitation in cardiac patients, rehabilitation is not fully known to be of value in post-percutaneous coronary intervention (PCI) patients. AIMS: To investigate the influence of cardiac rehabilitation on the incidence of major adverse cardiac events (MACEs) in post-PCI patients. METHODS: Retrospectively and nonrandomized 140 post-PCI patients (107 males, mean age 62 (7) years) participated in a 3-month rehabilitation program, starting 2 weeks post-PCI, while 83 post-PCI patients (54 males, mean age 68 (8) years) did not and were all followed up for 15 months. Data on cardiac medication prescription and incidence of MACE (including angina pectoris with or without reintervention, restenosis, myocardial infarction, revascularisation with re-PCI or CABG, and death) were collected. The relationship with cardiovascular risk factors including sex, smoking behaviour, obesity, diabetes mellitus, hypertension, familiar predisposition, and hypercholesterolemia was analysed. RESULTS: The incidence of total MACE in the rehabilitation group is significantly lower than in the control group (24% vs. 42%, respectively; P<0.005). The incidence of documented restenosis, angina pectoris with resulting reintervention, all revascularisations, and death is significantly lower in the rehabilitation group, compared with the control group. CONCLUSION: The incidence of MACE and restenosis is significantly lower when PCI patients are included in a cardiac rehabilitation program.

A multidimensional cancer rehabilitation program for cancer survivors: effectiveness on health-related quality of life.

OBJECTIVE: A multidimensional rehabilitation program for cancer survivors was developed to overcome cancer-related problems and to improve quality of life. The two purposes of the study were to describe the effectiveness of the program and to obtain information about patient preferences for multi or mono dimensional rehabilitation programs. METHODS SUBJECTS: cancer survivors with different diagnoses, and cancer-related physical and psychosocial problems. INTERVENTION: a 15-week rehabilitation program including individual exercise, sports, psycho-education, and information. Group-wise randomization was implemented by assigning one half of the patients to the complete program while the other half were allowed to choose which program components they considered relevant. MEASURES: Health-Related Quality of Life [RAND-36 and Rotterdam Symptom Check List (RSCL)], exercise capacity (symptom limited bicycle ergometry), muscle force (hand-held dynamometry), and patient preferences. Measurements were performed before (T0) and after the rehabilitation program (T1), and at a 3-month follow-up (T2). RESULTS: After the rehabilitation program, cancer survivors (n=63) displayed statistically significant improvements on health-related quality of life with effect sizes (ES) varying from 0.38 to 0.99 (RAND-36) and from -0.34 to -0.57 (RSCL), most persistent at 3-month follow-up. Furthermore, statistically significant improvements in exercise capacity and muscle force of upper and lower extremities were displayed after rehabilitation. If offered a choice, 80% of the patients prior to start and 58% of the patients after completion of the program indicated that they preferred the entire multidimensional program. CONCLUSION: A multidimensional rehabilitation program has statistically and clinically relevant beneficial effects on health-related quality of life, exercise capacity, and muscle force in cancer patients with different diagnoses. Furthermore, if offered the choice, the majority of cancer survivors seem to prefer multidimensional programs to programs with only one component.

Illness perceptions predict attendance at cardiac rehabilitation following acute myocardial infarction: a systematic review with meta-analysis.

OBJECTIVE: Early reports indicated that the illness perceptions of patients following acute myocardial infarction (AMI) predict attendance at cardiac rehabilitation. However, null findings have subsequently been reported, and there is variation between studies in terms of which illness perception constructs predict attendance. The aim of this meta-analysis was to examine whether illness perceptions really predict attendance at cardiac rehabilitation and to examine factors that moderate this relationship. METHODS: The strategy and procedures recommended by Hunter and Schmidt [Hunter JE, Schmidt FL. Methods of meta-analysis: correcting error and bias in research findings. Thousand Oaks (CA): Sage, 2004] were followed. Based on a systematic literature search, eight studies (N=906 patients) that examined the relationship between illness perceptions and attendance at cardiac rehabilitation were included. RESULTS: Four illness perception constructs significantly predicted attendance at cardiac rehabilitation: patients with more positive identity (r=.123), cure/control (r=.111), consequences (r=.081), and coherence (r=-.160) beliefs were more likely to attend cardiac rehabilitation. For all relationships, except that between cure/control beliefs and rehabilitation attendance, there was significant heterogeneity, which was attributable to two studies: one that assessed illness perceptions after leaving the hospital yielded higher effect size estimates, whereas another that involved an intervention yielded effect size estimates in the direction opposite to those of most other studies. The exclusion of these studies resulted in largely unchanged, but homogeneous, effect size estimates. CONCLUSION: Illness perceptions of AMI patients predict attendance at cardiac rehabilitation, although the effect sizes are small and often heterogeneous. AMI patients who view their condition as controllable, as symptomatic, and with severe consequences, and who feel that they understand their condition are more likely to attend.

Response to exercise rehabilitation in smoking and nonsmoking patients with intermittent claudication.

BACKGROUND: The purpose was to compare the changes in claudication pain, ambulatory function, daily physical activity, peripheral circulation, and health-related quality of life following a program of exercise rehabilitation in smoking and nonsmoking patients with peripheral arterial disease (PAD) limited by intermittent claudication. Methods and results Thirty-nine smokers (63 +/- 4 pack-year smoking history; mean +/- SE) and 46 nonsmokers (former smokers who had a 51 +/- 7 pack-year smoking history who quit 14 +/- 2 years prior to investigation) completed the study. The 6-month exercise rehabilitation program consisted of intermittent treadmill walking to near maximal claudication pain 3 days per week, with progressive increases in walking duration and intensity during the program. Measurements were obtained on each patient before and after rehabilitation. Following exercise rehabilitation the smokers and nonsmokers had similar improvements in these measures, as initial claudication distance increased by 119% in the smokers (P <.001) and by 97% in the nonsmokers (P <.001), and absolute claudication distance increased by 82% (P <.001) and 59% (P <.001) in the smokers and nonsmokers, respectively. Furthermore, exercise rehabilitation improved (P <.05) ambulatory function, daily physical activity, peripheral circulation, and health-related quality of life in the smokers and nonsmokers. CONCLUSION: Exercise rehabilitation is an effective therapy to improve functional independence in both smoking and nonsmoking patients with PAD limited by intermittent claudication. Therefore, smokers with intermittent claudication are prime candidates for exercise rehabilitation because their relatively low baseline physical function does not impair their ability to regain lost functional independence to levels similar to nonsmoking patients with PAD.

Impact of a changed inundation regime caused by climate change and floodplain rehabilitation on population viability of earthworms in a lower River Rhine floodplain.

River floodplains are dynamic and fertile ecosystems where soil invertebrates such as earthworms can reach high population densities. Earthworms are an important food source for a wide range of organisms including species under conservation such as badgers. Flooding, however, reduces earthworm numbers. Populations recover from cocoons that survive floods. If the period between two floods is too short such that cocoons cannot develop into reproductive adults, populations cannot sustain themselves. Both climate change and floodplain rehabilitation change the flooding frequency affecting earthworm populations. The present paper estimates the influence of climate change and floodplain rehabilitation on the viability of earthworm populations in a Dutch floodplain; the Afferdensche and Deestsche Waarden along the River Waal. This floodplain will be part of major river rehabilitation plans of the Dutch government. In those plans, the floodplain will experience the construction of a secondary channel and the removal of part of its minor embankment. To estimate the impact of these plans and climate change, we used a dataset of daily discharges for 1900-2003 for the River Rhine at the Dutch-German border. We perturbed this dataset to obtain two new datasets under climate change scenarios for 2050 and 2100. From the original and two projected datasets we derived the frequency distributions for the annual periods without inundations for the studied floodplain. We subsequently compared the duration of these inundation-free (dry) periods with the maturation age distribution for L. rubellus as derived from a Dynamic Energy Budget model. This comparison yielded in which parts of our study area and under which climate conditions the populations would still be viable, be able to adapt or become extinct. The results show that climate change has almost no adverse effect on earthworm viability. This is because climate change reduces the flooding frequency during the earthworms growing season. Floodplain rehabilitation, on the other hand, reduces the part of the floodplain area where populations can sustain themselves. Before rehabilitation, only 12% of the floodplain area cannot sustain a viable earthworm population. After rehabilitation, this increases to 59%, 28% of which is due to more frequent flooding. Enhanced exposure to soil contaminants may further suppress earthworm viability. This could frustrate further nature development and the viability of earthworm-dependent species such as the badger (Meles meles) or little owl (Athene noctua vidalli species), which is an objective of the river rehabilitation plans in the Netherlands.

[Possible factors influencing rehabilitation of the total laryngectomy patient using esophageal speech].

One of the handicaps of patients that have had a total laryngectomy is the loss of oral speech. There are three possibilities to rehabilitate these patients; surgery, voice prosthesis or esophageal speech. This last one appears as an inexpensive, non-invasive rehabilitation method; it does not need a complex learning and in spite of new technics, it continues to be an effective method in the social rehabilitation of laryngectomized patients. We have made a retrospective study of patients who underwent TL between 1992-1998 and that were rehabilitated by esophageal voice learning. Three factors have been evaluated: first, those related to the patient (gender, age, study level...); second, those related to the treatment itself [TL, pharyngolaryngectomy (PTL), TL plus radiotherapy...] and third, those related to the rehabilitation (technics, delayed on starting, number of sessions...). Data were compared with rehabilitation outcome: good (usually using esophageal voice), medium (speaking sometimes) and bad (not speaking). 74.1% had an acceptable outcome and they use esophageal voice with more or less difficulty to communicate, and this outcome increases to 95.8% when we do not take into account 7 patients who gave-up rehabilitation before finishing the first five sessions.

Effects of cardiac rehabilitation and beta-blocker therapy on heart rate variability after first acute myocardial infarction.

After acute myocardial infarction (AMI), rehabilitation with physical training increases parasympathetic tone. It is unknown whether such a favorable effect of exercise on the sympathovagal balance interacts with effects of other widespread therapies, such as beta blockers. In 53 patients after a first, uncomplicated AMI, we studied the combined short- and long-term influence on heart rate variability (HRV) of rehabilitation and beta blockade. Patients were divided into 3 groups: group 1 (n = 19) underwent rehabilitation with physical training; group 2 (n = 20) was taking beta blockers and underwent rehabilitation; group 3 (n = 14) was taking beta blockers and did not enter the rehabilitation program for logistic reasons. Patients were similar as to age, site of infarction, ejection fraction, left ventricular diameter, and baseline stress test duration. Measures of HRV (obtained from a 15-minute resting electrocardiogram) were the standard deviation of the mean RR interval (RRSD), the mean squared successive differences (MSSD), the percent of RR intervals differing >50 ms from the preceding one (pNN50), the low-(LF) and high-(HF) frequency components of the autoregressive power spectrum of the RR intervals and their ratio (LF/HF). Four weeks after AMI, there was less sympathetic predominance in groups 2 and 3 (i.e., patients taking beta blockers [p <0.05]). Rehabilitation modified HRV in groups 1 and 2 (p <0.05), with signs of increased parasympathetic tone (group 1: MSSD +25%, pNN50 +69%, LF/HF -40%; group 2: MSSD +41%, pNN50 +48%, LF/HF -39%). These changes persisted in the long term. In group 3, HRV was unchanged over time. Hence, after AMI, the effects of rehabilitation and beta blockers on HRV are not redundant: their association induces a more favorable sympathovagal balance, accelerating the recovery of a normal autonomic profile.
