Rigidity and bradykinesia reduce interlimb coordination in Parkinsonian gait.

OBJECTIVE: To assess the influence of rigidity and bradykinesia and the extent of dopaminergic degeneration on interlimb coordination during walking in early, drug-naive patients with Parkinsons disease (PD). DESIGN: The interlimb coordination was examined during a systematic manipulation of walking speed on a treadmill. The phase relations between arm and leg movements were related to the clinical measures of rigidity and bradykinesia as well as to the extent of dopaminergic degeneration. SETTING: Movement disorders outpatient clinic (including motion analysis laboratory) and a nuclear medicine department of a university hospital. PARTICIPANTS: Twenty-nine early and drug-naive PD patients. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The interlimb coordination during walking was evaluated by studying the (continuous) relative phase relations between movements of arms and legs. The clinical assessment of rigidity and bradykinesia was performed by using the Unified Parkinson Disease Rating Scale. The dopaminergic degeneration was expressed as striatal 2beta-carboxymethoxy-3beta-(4-iodophenyl) tropane (beta-CIT) single-photon emission computed tomography (SPECT) binding. RESULTS: The mean relative phase between arm and leg movements increased significantly with walking speed in all patients. Significant correlations were found between the rigidity and bradykinesia and the coordination measures ( P </=.007), as well as contralateral striatal [ 123 I]beta-CIT SPECT binding and coordination measures ( P <.001), in terms of asymmetry indices. CONCLUSIONS: Early, drug-naive PD patients in this sample were able to adapt their coordination patterns when walking speed was systematically manipulated. However, bradykinesia and rigidity as well as the extent of degeneration of the dopaminergic system were associated with a limited adaptive ability (flexibility) in movement coordination. The combination of a drug treatment that controls bradykinesia and rigidity and a physical therapy exercise programs possibly using external cues mechanisms are required to obtain relevant effects on gait in PD patients.

Resistance training improves gait kinematics in persons with multiple sclerosis.

OBJECTIVE: To evaluate the effects of an 8-week lower-body resistance-training program on walking mechanics in persons with multiple sclerosis (MS). DESIGN: Repeated-measures design, evaluating gait kinematics before and after an 8-week progressive resistance-training intervention. SETTING: Biomechanics laboratory and fitness center (with conventional, commercially available resistance-training equipment). PARTICIPANTS: Eight ambulatory subjects with MS (age, 46.0+/-11.5 y) with Expanded Disability Status Scale scores ranging from 2.5 to 5.5. INTERVENTION: An 8-week progressive resistance-training program. MAIN OUTCOME MEASURES: Kinematic gait parameters including knee range of motion, duration of stance, swing, and double-support phases in seconds and as percentages of the stride time, percentage of stride time spent in stance, swing, and double-support phases, step length, foot angle, stride length, velocity, step width, and toe clearance for both the more affected and less affected lower limbs. Isometric strength, 3-minute stepping, fatigue, and self-reported disability were also measured. RESULTS: After 2 months of resistance training, there were significant increases (P<.05) in percentage of stride time in the swing phase, step length, stride length, and foot angle; and significant decreases (P<.05) in percentage of stride time in the stance and double-support phases, duration of the double-support phase, and toe clearance. Isometric leg strength improved (P<.05) in 2 of the 4 muscle groups tested. Fatigue indices decreased (P=.04), whereas self-reported disability tended to decrease (P=.07) following the training program. Three-minute stepping increased by 8.7%. CONCLUSIONS: Resistance training may be an effective intervention strategy for improving walking and functional ability in moderately disabled persons with MS.

Effectiveness of gait training using an electromechanical gait trainer, with and without functional electric stimulation, in subacute stroke: a randomized controlled trial.

OBJECTIVE: To compare the therapeutic effects of conventional gait training (CGT), gait training using an electromechanical gait trainer (EGT), and gait training using an electromechanical gait trainer with functional electric stimulation (EGT-FES) in people with subacute stroke. DESIGN: Nonblinded randomized controlled trial. SETTING: Rehabilitation hospital for adults. PARTICIPANTS: Fifty patients were recruited within 6 weeks after stroke onset; 46 of these completed the 4-week training period. INTERVENTION: Participants were randomly assigned to 1 of 3 gait intervention groups: CGT, EGT, or EGT-FES. The experimental intervention was a 20-minute session per day, 5 days a week (weekdays) for 4 weeks. In addition, all participants received their 40-minute sessions of regular physical therapy every weekday as part of their treatment by the hospital. MAIN OUTCOME MEASURES: Five-meter walking speed test, Elderly Mobility Scale (EMS), Berg Balance Scale, Functional Ambulatory Category (FAC), Motricity Index leg subscale, FIM instrument score, and Barthel Index. RESULTS: The EGT and EGT-FES groups had statistically significantly more improvement than the CGT group in the 5-m walking speed test (CGT vs EGT, P=.011; CGT vs EGT-FES, P=.001), Motricity Index (CGT vs EGT-FES, P=.011), EMS (CGT vs EGT, P=.006; CGT vs EGT-FES, P=.009), and FAC (CGT vs EGT, P=.005; CGT vs EGT-FES, P=.002) after the 4 weeks of training. No statistically significant differences were found between the EGT and EGT-FES groups in all outcome measures. CONCLUSIONS: In this sample with subacute stroke, participants who trained on the electromechanical gait trainer with body-weight support, with or without FES, had a faster gait, better mobility, and improvement in functional ambulation than participants who underwent conventional gait training. Future studies with assessor blinding and larger sample sizes are warranted.

Effects of circuit resistance training on fitness attributes and upper-extremity pain in middle-aged men with paraplegia.

OBJECTIVE: To examine the effects of circuit resistance exercise (CRT) training on muscle strength, endurance, anaerobic power, and shoulder pain in middle-aged men with paraplegia. DESIGN: Repeated testing. SETTING: Academic medical center. PARTICIPANTS: Seven men (age range, 39-58y) with motor-complete paraplegia from T5 to T12 and confirmed shoulder pain occurring during daily activities. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Subjects underwent a 4-month CRT program using alternating resistance maneuvers and high-speed, low-resistance arm exercise. One-repetition maximal force was measured before training and monthly thereafter. Pretraining and posttraining peak oxygen uptake (Vo(2)peak) was measured by graded arm testing. Anaerobic power was measured before and after training using a 30-second Wingate Anaerobic Test. Shoulder pain was self-evaluated by an index validated for people with spinal cord injury (Wheelchair Users Shoulder Pain Index [WUSPI]). RESULTS: Strength increases ranging from 38.6% to 59.7% were observed for all maneuvers (P range, .005-.008). Vo(2)peak increased after training by 10.4% (P=.01), and peak and average anaerobic power increased by 6% (P=.001) and 8.6% (P=.005), respectively. WUSPI scores +/- standard deviation were lowered from 31.9+/-24.8 to 5.7+/-5.9 (P=.008), with 3 of 7 subjects reporting complete resolution of shoulder pain. CONCLUSIONS: CRT improves muscle strength, endurance, and anaerobic power of middle-aged men with paraplegia while significantly reducing their shoulder pain.

Circuit training for elderly patients with chronic obstructive pulmonary disease: a preliminary study.

To examine the efficacy of the circuit training in elderly patients with chronic obstructive pulmonary disease (COPD), we evaluated muscle forces of the upper and lower extremities and respiratory muscles, exercise tolerance and quality of life (QOL) before and after the circuit training in 10 male patients with mild to severe COPD. The circuit training improved muscle forces of the upper and lower extremities and abdominal muscles (P < 0.05), and 6 min walking distance (P < 0.05). Emotional function and mastery in the Chronic Respiratory Disease Questionnaire scores (P < 0.05) were also improved after the circuit training. The circuit training designed in the present study was effective to improve the QOL in elderly COPD patients.

Multidisciplinary management in geriatric day-hospital is beneficial for elderly fallers: a prospective study of 28 cases.

We determined whether management including medical, psychological, and physiotherapeutic approaches, over a period of 6 weeks, has a beneficial effect on motor abilities, psychological status, and independence of elderly fallers with psychomotor disadaptation syndrome (PDS). We included 28 subjects (mean age 81.4 years). They were assessed from a medical, motor, and psychological point of view at both the inclusion and the end of the multidisciplinary intervention. A follow-up was conducted with multidisciplinary assessment at 6 and 9 months after the beginning of the study in order to evaluate duration of benefits of the management. The statistical analysis concerned only subjects who took part in the total multidisciplinary program, i.e., 14 subjects. The multidisciplinary intervention had an overall positive impact on motor abilities as shown by the increase in the mini-motor test scores, the rate of success in rising from the floor and decrease of time for the dual task. This study also showed a reduction in the fear of falling and a decrease in the rate of fallers. This positive effect on motor abilities, fear of falling and rate of fallers was sustained until 9 months after the beginning of the multidisciplinary management. This study shows the importance of a multidisciplinary management of elderly fallers with PDS.

What are the goals and principles of management in the early treatment of rheumatoid arthritis?

The management of patients with new-onset rheumatoid arthritis (RA) requires an awareness of the potential issues and needs that are unique to each patient with regards to their perceptions of their disease, physical needs and nutritional issues. Arthritis specialists should have a clear approach to the goals of management that are specific to patients with early rheumatoid arthritis (ERA). In this chapter, evidence for the goals and principles of management in the early treatment of RA is discussed. Patient education, the role of self-management, physical therapies, exercise, diet and drug management are addressed. This chapter aims to provide clinicians with a clear understanding of which interventions have supporting evidence and where further research is required. Where evidence for patients with ERA is lacking, evidence from patients with established RA is reviewed.

Idiographic outcome analyses of the clinical significance of two interventions for patients with musculoskeletal pain.

UNLABELLED: This study adopted a perspective of the individual to define domains of everyday life for the analysis of clinically meaningful change. The purpose was to compare the clinical significance of two interventions for patients with musculoskeletal pain, applying an idiographic outcome measure, The Patient Goal Priority Questionnaire, in combination with the Jacobson and Truax methodology [(1991). CLINICAL SIGNIFICANCE: A statistical approach to defining meaningful change in psychotherapy research. Journal of Consulting and Clinical Psychology, 67 (3), 300-307] for determination of clinical significance. The concurrent validity of the outcome variables behavioral performance, satisfaction with behavioral performance, and fulfilled pre-treatment expectations was also studied. Eighty-two patients, randomized to either individually tailored behavioral medicine treatment (experimental group) or physical exercise therapy (control group) were evaluated at baseline and 3 months post-treatment regarding behavioral treatment goals. The experimental intervention had high impact on participants' performance of their highest ranked everyday life activities, and resulted in larger proportions of clinically significant outcomes compared with controls. The concurrent validity of the outcomes was high for those reporting clinically significant changes, but more generally, there was a moderate agreement across outcome categories. The individual should be the unit for analyses of clinical significance to enhance the ecological validity of the construct. Further development of idiographic outcome measures is necessary, as is the inclusion in pain intervention research.

Urinary incontinence: behavioral modification therapy in older adult.

Urinary incontinence is common in the elderly population;however, less than half the people who have this problem are examined or treated. The Agency for Health Care Policy and Research recommends behavioral interventions before other forms of treatment in patients who are diagnosed with stress, urge, or mixed incontinence after a basic evaluation. Behavioral treatments are safe, effective, and low risk and have no documented side effects. They also can be used as an adjunct to other therapies, such as pharmacologic and surgical interventions.

An endurance-strength training regime is effective in reducing myoelectric manifestations of cervical flexor muscle fatigue in females with chronic neck pain.

OBJECTIVE: The purpose of this study was to investigate whether an endurance-strength training program is effective in reducing myoelectric manifestations of sternocleidomastoid (SCM) and anterior scalene (AS) muscle fatigue which have been found to be greater in people with chronic neck pain. METHODS: Fifty-eight female patients with chronic non-severe neck pain were randomized into one of two 6-week exercise intervention groups: an endurance-strength training regime for the cervical flexor muscles or a referent exercise intervention involving low load retraining of the cranio-cervical flexor muscles. The primary outcomes were a change in maximum voluntary contraction (MVC) force and change of the initial value and rate of change of the mean frequency, average rectified value and conduction velocity detected from the SCM and AS muscles during sub-maximal isometric cervical flexion contractions at 50, 25 and 10% MVC. RESULTS: At the 7th week follow-up assessment, the endurance-strength training group revealed a significant increase in MVC force and a reduction in the estimates of the initial value and rate of change of the mean frequency for both the SCM and AS muscles (P<0.05). Both exercise groups reported a reduced average intensity of neck pain and reduced neck disability index score (P<0.05). CONCLUSIONS: An endurance-strength exercise regime for the cervical flexor muscles is effective in reducing myoelectric manifestations of superficial cervical flexor muscle fatigue as well as increasing cervical flexion strength in a group of patients with chronic non-severe neck pain. SIGNIFICANCE: Provision of load to challenge the neck flexor muscles is required to reduce the fatigability of the SCM and AS muscles in people with neck pain. Improvements in cervical muscle strength and reduced fatigability may be responsible for the reported efficacy with this type of exercise program.

Equine rehabilitation therapy for joint disease.

The principles of physical rehabilitation therapy can be applied to the horse to provide a reduction in discomfort and dysfunction associated with the various forms of joint disease. Physical agents,such as ice, heat, electricity, sound, light, magnetic fields, compression, and movement, can be used by the rehabilitation therapist to attempt to control pain, reduce swelling, and restore optimal movement and function in the affected joint. The equine therapist's attention is focused not only on the affected joint but on the body as a whole to manage secondary or compensatory problems.

Randomised controlled trial evaluating lifestyle interventions in people with impaired glucose tolerance.

AIM: To evaluate the effectiveness of lifestyle interventions in people with impaired glucose tolerance (IGT). METHODS: Participants with IGT (n=78), diagnosed on two consecutive oral glucose tolerance tests (OGTTs), were randomly assigned to a 2-year lifestyle intervention or to a control group. Main outcome measures were changes from baseline in: nutrient intake; physical activity; anthropometry, glucose tolerance and insulin sensitivity. Measurements were repeated at 6, 12 and 24 months follow-up. RESULTS: After 24 months follow-up, there was a significant fall in total fat consumption (difference in change between groups (Delta intervention-Delta control)= -17.9, 95% confidence interval (CI) -33.6 to -2.1g/day) as a result of the intervention. Body mass was significantly lower in the intervention group compared with controls after 6 months (-1.6, 95% CI -2.9 to -0.4 kg) and 24 months (-3.3, 95% CI -5.7 to -0.89 kg). Whole body insulin sensitivity, assessed by the short insulin tolerance test (ITT), improved after 12 months in the intervention group (0.52, 95% CI 0.15-0.89%/min). CONCLUSIONS: These findings complement the findings of the Finnish Diabetes Prevention Study and the American Diabetes Prevention Study, both of which tested intensive interventions, by showing that pragmatic lifestyle interventions result in improvements in obesity and whole body insulin sensitivity in individuals with IGT, without change in other cardiovascular risk factors.

Optimal dose and exercise modality to improve HbA1c in older adults with type 2 diabetes mellitus: a systematic review with pairwise, network, and dose-response meta-analyses.

We aimed to compare exercise modalities and evaluate dose-response relationships with glycemic control including continuous aerobic exercise (CAE), resistance training (RT), combined exercise (CE), mind-body exercise (MBE), and high-intensity interval training (HIIT) in older adults with type 2 diabetes mellitus (T2DM). Three databases were searched for randomized controlled trials of exercise interventions in older adults with T2DM reporting glycated hemoglobin (HbA1c). Pairwise, Bayesian network, and dose-response meta-analyses were conducted. Compared with control, HIIT demonstrated the largest estimated reduction (MD = -0.95%; 95% CrI -1.45, -0.49), followed by CE (MD = -0.59%; 95% CrI -0.93, -0.25), CAE (MD = -0.46%; 95% CrI -0.69, -0.24), MBE (MD = -0.42%; 95% CrI -0.76, -0.10), and RT (MD = -0.29%; 95% CrI -0.51, -0.08). Dose-response network meta-analyses suggested a non-linear association between overall exercise dose and HbA1c reduction, with maximal estimated benefits at approximately 704 METs-min/week with the 95% CrI excluding zero between 241 and 920 METs-min/week. HIIT demonstrated the steepest estimated dose-response relationship, but with wider credible intervals. Other exercise modalities showed more gradual dose-response patterns across their estimated effective ranges. Our findings suggest that exercise prescription for older adults with T2DM should be individualized according to exercise modality, dose, and health status.

Combined endurance/resistance training reduces NT-proBNP levels in patients with chronic heart failure.

AIMS: This study was designed to evaluate the effects of combined endurance/resistance training on NT-proBNP levels in patients with chronic heart failure (CHF). The safety of resistive weight training for patients with CHF is questioned. Possible detrimental effects include an increase in ventricular diastolic pressure and secondary unfavourable remodelling. Circulating levels of the N-terminal fragment of brain natriuretic peptide (NT-proBNP) reflect left ventricular diastolic wall stress and are strongly related to mortality and treatment success in CHF. METHODS AND RESULTS: In this study, 27 consecutive patients with stable CHF and left ventricular ejection fraction (LVEF) <35% were enrolled in a 4 months non-randomized combined endurance/resistance training programme. Blood sampling for measurement of NT-proBNP, functional assessment, cardiopulmonary exercise testing, echocardiography and radionuclide angiography were performed at entry and after 4 months. After 4 months, exercise training caused a significant reduction in circulating concentrations of NT-proBNP (2124+/-397 pg/ml before, 1635+/-304 pg/ml after training, p=0.046, interaction), whereas no changes were observed in an untrained heart failure control group. NYHA functional class (p=0.02, interaction), maximal (peak VO2: p=0.035, interaction; maximal workload: p<0.00001, interaction) and submaximal (workload at anaerobic threshold: p=0.001, interaction; rate-pressure product at anaerobic threshold: p=0.001, interaction) exercise parameters as well as work efficiency (Wattmax/VO2peak: p=0.0001, interaction) were significantly improved. In addition, a decrease in left ventricular end-systolic diameter was observed in the trained heart failure group (p=0.016). CONCLUSION: Four months of combined endurance/resistance training significantly reduced circulating levels of NT-proBNP in patients with CHF, without evidence of adverse remodelling. Exercise training might offer additional non-pharmacological modulation of the activated neurohormonal pathways in the setting of CHF.

The effect of physical training in chronic heart failure.

BACKGROUND: Supervised cardiac rehabilitation programs have been offered to patients following myocardial infarct (MI), coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) for many years. However, limited information is available on the usefulness of rehabilitation programs in chronic heart failure (CHF). The aim of our study was to evaluate the outcome of supervised physical training on CHF patients by measuring both central and peripheral factors. METHODS: This was a prospective randomized study, including 43 patients with CHF, New York Heart Association (NYHA) class II or III, mean age 68 years. After initial measurements of VO2 peak, 6 min walk distance, muscle strength, plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), echocardiogram, measurements of pulmonary function and quality of life questionnaire, patients were randomized to either a training group (n = 21) or a control group (n = 22). The training group had supervised aerobic and resistance training program twice a week for five months. After the training program was completed, all measurements were repeated in both groups. RESULTS: No training related adverse events were reported. Significant improvement was found between groups in the six minute walk test (+37.1 m vs. +5.3 m, p = 0.01), work load on the bicycle exercise test (+6.1 W vs. +2.1 W, p = 0.03), time on the bicycle exercise test (+41 s vs. +0 s, p = 0.02) and quadriceps muscle strength test (+2.8 kg. vs. +0.2 kg., p = 0.003). Quality of life factors that reflect exercise tolerance and general health, improved significantly in the training group compared to the control group. No other significant changes were found between the two groups. CONCLUSION: Supervised physical training as used in this study appears safe for CHF patients in NYHA class II or III. The improvement in functional capacity observed in the training group seems to be related to peripheral factors rather than in central cardiovascular performance.

Relative tolerance to upper- and lower-limb aerobic exercise in patients with peripheral arterial disease.

OBJECTIVES: To investigate the effects of peripheral arterial disease (PAD) on relative tolerance to upper- and lower-limb aerobic exercise. METHODS: Peak cardiorespiratory responses evoked by an incremental arm-cranking test (ACT) and an incremental leg-cranking test (LCT) were compared in patients with PAD (N=101; median age 69 year, range 50-85 years). Claudication distance (CD) and total distance before intolerable claudication pain (maximum walking distance: MWD) were also assessed during walking. RESULTS: Peak oxygen consumption (V O(2)) for the ACT was 94% of that measured for the LCT (1.01+/-0.03 versus 1.10+/-0.03lmin(-1), respectively; P<0.001), but in a significant proportion of patients (35%; P<0.001), exceeded that recorded for the LCT. The ratio of upper- to lower-limb peak V O(2) was higher (0.98+/-0.04 compared to 0.98+/-0.05lmin(-1) and 1.00+/-0.06 compared to 1.21+/-0.06lmin(-1); P<0.01), whereas walking performance (CD: 94+/-14 versus 187+/-25 m, P<0.01; MWD: 227+/-20 versus 394+/-33 m, P<0.01) was lower for patients in the lowest ankle to brachial pressure index quartile compared to patients in the highest quartile, respectively. CONCLUSION: Upper-limb aerobic conditioning could be a useful exercise stimulus for maintaining or improving cardiorespiratory function in patients with severe PAD as they have a greater relative upper-limb aerobic power.

The functional impact of an individualized, graded, outpatient pulmonary rehabilitation in end-stage chronic obstructive pulmonary disease.

OBJECTIVE: To evaluate the functional impact of an individualized outpatient pulmonary rehabilitation program in end-stage chronic obstructive pulmonary disease (COPD). METHODS: Patients with end-stage COPD were admitted into a 6-week comprehensive outpatient pulmonary rehabilitation program that was "packaged" for each patient. We compared spirometric parameters, exercise tolerance, level of breathlessness, and intensity of work before and after rehabilitation. RESULTS: Of 45 eligible patients, only 14 consented to participate in the study. All 14 patients had forced expiratory volume in 1 second <35% of predicted, and 10 patients (72%) had a 6-minute walk test <180 m. The level of breathlessness was between 7 (moderate to severely breathless) and 10 (maximally breathless) on the Visual Analogue Scale in all patients. After the program, there was significant improvement in the FEV 1 P = 0.04), forced vital capacity P = 0.0045), 6-minute walk test P = 0.00047), and shuttle-walk test (9 of 14 patients). All patients had some improvement in level of dyspnea. CONCLUSIONS: Individualized outpatient pulmonary rehabilitation in end-stage COPD can produce a measurable improvement in spirometry and exercise tolerance with a favorable impact on the level of physical activity.
