Knee movement patterns of injured and uninjured adolescent basketball players when landing from a jump: a case-control study.

BACKGROUND: A common knee injury mechanism sustained during basketball is landing badly from a jump. Landing is a complex task and requires good coordination, dynamic muscle control and flexibility. For adolescents whose coordination and motor control has not fully matured, landing badly from a jump can present a significant risk for injury. There is currently limited biomechanical information regarding the lower limb kinetics of adolescents when jumping, specifically regarding jump kinematics comparing injured with uninjured adolescents. This study reports on an investigation of biomechanical differences in landing patterns of uninjured and injured adolescent basketball players. METHODS: A matched case-control study design was employed. Twenty-two basketball players aged 14-16 years participated in the study: eleven previously knee-injured and eleven uninjured players matched with cases for age, gender, weight, height and years of play, and playing for the same club. Six high-speed, three-dimensional Vicon 370 cameras (120 Hz), Vicon biomechanical software and SAS Version 8 software were employed to analyse landing patterns when subjects performed a "jump shot". Linear correlations determined functional relationships between the biomechanical performance of lower limb joints, and paired t-tests determined differences between the normalised peak biomechanical parameters. RESULTS: The average peak vertical ground reaction forces between the cases and controls were similar. The average peak ground reaction forces between the cases and controls were moderately correlated (r = -0.47). The control (uninjured) players had significantly greater hip and knee flexion angles and significantly greater eccentric activity on landing than the uninjured cases (p < 0.01). CONCLUSION: The findings of the study indicate that players with a history of knee injuries had biomechanically compromised landing techniques when compared with uninjured players matched for gender, age and club. Descriptions (norms) of expected levels of knee control, proprioceptive acuity and eccentric strength relative to landing from a jump, at different ages and physical developmental stages, would assist clinicians and coaches to identify players with inappropriate knee performance comparable to their age or developmental stage.

Longitudinal investigation of low back pain in Australian adolescents: a five-year study.

BACKGROUND AND PURPOSE: Adolescent spinal pain is a worldwide concern, with few longitudinal studies to validate concerns that an increasing number of adolescents report pain with age. The aim of the present study was to track reports of low back pain (LBP) in adolescents each year over a five-year period (between the ages of 13 and 17 years). METHOD: A longitudinal, observational, repeated-measures study, commencing in 1999. We followed a group of South Australian students throughout five years of high schooling, reporting on prevalence of recent low back pain each year. RESULTS: In 1999, data were collected from 434 13-year-olds (82.5% eligible students). In the subsequent four years, the response rate from the 1999 sample was, respectively, 72.2%, 69.1%, 56.2% and 40.1%. A significant increasing prevalence of recent LBP was reported for girls and boys. The odds of girls reporting recent LBP in the final study year (fifth year) compared with the first year was 4.4 (95% CI 1.9-10.1),for boys 1.6 (95% CI 0.7-3.7). New cases of girls' recent LBP decreased consistently over the study (90% in 2000, 46.1% in 2001, 42.1% in 2002 and 33% in 2003). New boys' cases decreased in the second and third study years (85% in 2000, 45% in 2001) then increased (45.8% in 2002, 63.6% in 2003), suggesting less established patterns of occurrence. CONCLUSIONS: New cases of LBP reflected a decreasing percentage of total LBP reports over each study year for girls (suggesting increasing consistency of LBP occurrence with age). A different pattern was observed for boys, with a reversal of the downward trend after age 15 years, showing an increased percentage of LBP reports that reflected new cases in the final two study years.

Reliability of upright posture measurements in primary school children.

BACKGROUND: Correct upright posture is considered to be a measure of good musculoskeletal health. Little is known about the usual variability of children's upright standing posture. The aim of this study was to assess differences between repeated measures of upright posture in a group of primary school children. METHODS: Sagittal plane photographs of usual, relaxed upright standing posture of 38 boys and girls aged 5-12 years were taken twice within an hour. Reflective markers were placed over the canthus, tragus, C7 spinous process, greater trochanter and lateral malleolus. Digitising software was used to calculate the x,y plane coordinates, from which five postural angles were calculated (trunk, neck, gaze, head on neck, lower limb). Height, weight, motor control estimates (as measured by the Brace Tests) and presence of recent pain were recorded for each child, and the association between the first test measure of posture angles and these factors was assessed using linear regression and ANOVA models. Multiple ANOVA models were applied to analyse the effect of repeated testing, and significant predictors on the angles. RESULTS: Four of the five postural angles (trunk, neck, head on neck, lower limb) were significantly influenced by age. As age was strongly associated with height (r2 = 0.84) and moderately associated with weight and motor control (r2 = 0.67, 0.56 respectively), these developmental parameters may well explain the age effect on angles. There was no relationship between age and pain reported on either the testing day, or recently, and there was no gender influence on any angle. There was no significant effect of repeated testing on any angle (ICC>0.93). None of the hypothesized predictors were associated with differences in angles from repeated testing. CONCLUSION: This study outlined the variability of relaxed upright standing posture of children aged 5-12 years, when measured twice in an hour. Age influenced the size of the angles but not the variability. While the subject numbers in this study are small, the findings provide useful information on which further studies in posture and its development in pre-adolescent children can be based.

Teaching Filipino physiotherapists on-shore: an Australian-Filipino collaborative postgraduate health education initiative.

INTRODUCTION: This paper outlines a collaborative, cross-national educational initiative, commenced in 2001, in which an Australian university provided clinical and research education assistance to a Filipino University. The aim was to establish the first Filipino Master of Science in Physical Therapy program that would train physiotherapists in their home country using best available content and teaching expertise. PROCESS: Principles of quality transnational education underpinned the program design and contractual agreements. Australian educational input was tailored to local constraints to ensure efficient and effective delivery of high quality, relevant material. Approximately 60% of the inaugural program was delivered by Australian educators in one-week intensive courses on-shore in the Philippines, using local facilities and case-scenarios. Follow-up support and evaluation were provided by video, email, written workbooks and assignments once these educators returned to Australia. Filipino graduates, who were competent with course content, taught the remaining subjects. In line with an aim of empowering Filipino graduates to assume responsibility for teaching all aspects of the program by 2006, the Australian educators are now teaching less than 25% of the course content to subsequent student cohorts. After 2006, they will provide mentorship only to the program. RESULTS: In 2003, 12 students in the first cohort graduated with Master of Science in Physical Therapy from the University of Santo Tomas (UST). Twenty-four students subsequently enrolled in the second cohort (commenced 2003) and 21 students into the third cohort (commenced 2004). Six of the inaugural graduate cohort are currently acting as tutors for the Australian educators and will assume full teaching roles in 2006. Comparison of feedback from student evaluations at UST indicates significant improvements in teaching quality for the graduates from the inaugural program. Research activity and publications have also increased as a result of completion of the program. DISCUSSION: Such a cross-institutional, cross-national program has not been described previously for physiotherapy, and no other similar health program (for nursing) evaluated the educational processes in the manner used in this program. The program met its aims and has produced sustainable educational outcomes and outputs. CONCLUSION: Future scholarly activities between the two institutions include extension of postgraduate training to other health disciplines, cross-institutional PhD student enrollments and collaborative research.

Expanded paper towel test: an objective test of urine loss for stress incontinence.

AIM: To investigate the repeatability of a short stress test of coughing and jumping (the expanded Paper Towel Test (PTT)) to quantify urine loss in stress incontinent adult women. MATERIALS AND METHODS: In the laboratory, the reliability of two methods of measuring the size of the wet area, produced by a typical volume of water titrated onto paper towel was investigated and some absorbency properties of the brand of towel used were quantified. Thirty one women performed a provocative coughing and jumping test on consecutive days using a "perineal pad" of paper towel. The repeatability coefficient was calculated. RESULTS: The provocative test was repeatable to within 2.8 ml of urine loss, but with the exclusion of one anomalous result, the repeatability improved to lie within 1 ml. The coefficient of variation (CV) for the between-method differences (computer scanning and graph paper) was 1.27%. A volume of 1 ml of water produced a wet area of 25.7 cm2. The range of measurable areas corresponded to volumes of 0.005-8 ml. Standardization of method is required because the size of the wet area differed by manufacturer of paper towel (P < 0.01, two products compared) and with time elapsed since titration (P < 0.01). CONCLUSIONS: The "expanded PTT" is a simple tool for quantification of urine loss (0.005-8 ml) in women to 72 years with stress incontinence. With a suggested modification, it should prove reliable for detection of between-visit differences of 1 ml. The reliability of the test is dependent upon the use of standard protocol and paper towel with known volume-area ratio. To improve clinical diagnosis, it can also be used with any brand of paper towel to confirm the sign of stress incontinence on exertion.

Pre-manipulative testing of the cervical spine review, revision and new clinical guidelines.

Members of the Manipulative Physiotherapists Association of Australia (now Musculoskeletal Physiotherapy Australia) were surveyed to determine their use of cervical manipulation, compliance with and attitudes to the Australian Physiotherapy Association's (APA) Protocol for Pre-manipulative Testing of the Cervical Spine, and the incidence of adverse effects from cervical manipulation. The questionnaire was mailed to 740 members and returned by 480 members (65%). Cervical manipulation (84.5%) and passive mobilization (99.8%) were used by a high percentage of respondents. Most were familiar with the protocol with 63% supporting its continued endorsement. Adverse effects were reported at a rate of one per 1000 years of practice (or 0.003/week). The most common effects were symptoms potentially related to VBI (94.4% responses), with no reported major complications. Only 37.1% of respondents always informed the patient about potential dangers of cervical manipulation and consent was sought on every occasion by 33% of respondents. The results suggest that the use and interpretation of the protocol are variable among members of MPA. The risk of adverse effects from manipulative (musculoskeletal) physiotherapy practice, including cervical manipulation, appears to be very low. Recommendations for revision of the protocol were made on the basis of results of the survey and treatment diary, in addition to a review of the literature related to testing for vertebro-basilar insufficiency, adverse incidents related to cervical mobilizing and manipulative technique, differentiating features of VBI related dizziness and vertigo related to benign paroxysmal positional vertigo (BPPV) and current issues surrounding informed consent. Finally, a summary of the content of the new Clinical Guidelines for Pre-Manipulative Testing of the Cervical Spine (APA, 2000) is provided.

Experiences of elderly patients regarding independent community living after discharge from hospital: a longitudinal study.

OBJECTIVE: To describe the reported experiences of elderly patients regarding their transition from an acute hospital to independent community living. DESIGN: Observational longitudinal study based on semi-structured interviews conducted monthly for 6 months following discharge from hospital. SETTING: Four South Australian acute hospitals. Patients. One hundred elderly patients who faced a long-term change in health status and/or in their ability to manage practical aspects of daily living. MAIN OUTCOME MEASURES: Experiences in managing change in health status, social circumstances and independent community living. RESULTS: Few patients believed that discharge plans made in hospital had assisted their return to independent community living. Discharge planning addressed mainly formal health services rather than practical aspects of daily living. Many patients implemented innovative solutions when formal services were unavailable or inadequate. Pain, tiredness, loss of mobility, and grief over loss of previous abilities were frequent, long lasting sequelae to illness, and few discharge plans prepared patients to deal with this. CONCLUSIONS: Elderly patients who have left hospital to face a permanent change in health status often regret that they have not been better prepared for what lies ahead in terms of more specific information about their condition, linked with practical discharge plans that prepare them for their period of convalescence. We suggest that the underlying problem is a disjunction between the multiple systems involved in hospital discharge planning, primary medical care, disability-oriented community health services, and informal community services.

The postural effects of load carriage on young people--a systematic review.

BACKGROUND: Spinal pain in young people is a significant source of morbidity in industrialised countries. The carriage of posterior loads by young people has been linked with spinal pain, and the amount of postural change produced by load carriage has been used as a measure of the potential to cause tissue damage. The purpose of this review was to identify, appraise and collate the research evidence regarding load-carriage related postural changes in young people. METHODS: A systematic literature review sought published literature on the postural effects of load carriage in young people. Sixteen databases were searched, which covered the domains of allied health, childcare, engineering, health, health-research, health-science, medicine and medical sciences. Two independent reviewers graded the papers according to Lloyd-Smith's hierarchy of evidence scale. Papers graded between 1a (meta-analysis of randomised controlled trials) and 2b (well-designed quasi-experimental study) were eligible for inclusion in this review. These papers were quality appraised using a modified Crombie tool. The results informed the collation of research evidence from the papers sourced. RESULTS: Seven papers were identified for inclusion in this review. Methodological differences limited our ability to collate evidence. CONCLUSIONS: Evidence based recommendations for load carriage in young people could not be made based on the results of this systematic review, therefore constraining the use of published literature to inform good load carriage practice for young people.

Virtual reality as a pediatric pain modulation technique: a case study.

Post-surgical pain has been consistently reported in pediatrics as being difficult to manage and limiting to surgical outcomes. Pain management of children is not ideal, and some children unable to tolerate traditional pharmacological agents. Virtual reality (VR) is a new and promising form of non-pharmacologic analgesia. This case study explored the use of VR analgesia with a 16-year-old patient with cerebral palsy participating in a twice-daily physiotherapy program following Single Event Multi-Level Surgery. Over 6 days, the patient spent half of his physiotherapy sessions using VR and the other half without (order randomized). Traditional pharmacological pain management was administered throughout the trial. Using a subjective pain scale (five faces denoting levels of pain), the patient's overall pain ratings whilst in the VR (experimental) condition were 41.2% less than those in the no-VR (control) condition. This case report provides the first evidence that VR may serve as a powerful non-pharmacologic analgesic for children following surgery.

Adolescent standing postural response to backpack loads: a randomised controlled experimental study.

BACKGROUND: Backpack loads produce changes in standing posture when compared with unloaded posture. Although 'poor' unloaded standing posture has been related to spinal pain, there is little evidence of whether, and how much, exposure to posterior load produces injurious effects on spinal tissue. The objective of this study was to describe the effect on adolescent sagittal plane standing posture of different loads and positions of a common design of school backpack. The underlying study aim was to test the appropriateness of two adult 'rules-of-thumb'-that for postural efficiency, backpacks should be worn high on the spine, and loads should be limited to 10% of body weight. METHOD: A randomised controlled experimental study was conducted on 250 adolescents (12-18 years), randomly selected from five South Australian metropolitan high schools. Sagittal view anatomical points were marked on head, neck, shoulder, hip, thigh, knee and ankle. There were nine experimental conditions: combinations of backpack loads (3, 5 or 10% of body weight) and positions (backpack centred at T7, T12 or L3). Sagittal plane photographs were taken of unloaded standing posture (baseline), and standing posture under the experimental conditions. Posture was quantified from the x (horizontal) coordinate of each anatomical point under each experimental condition. Differences in postural response were described, and differences between conditions were determined using Analysis of Variance models. RESULTS: Neither age nor gender was a significant factor when comparing postural response to backpack loads or conditions. Backpacks positioned at T7 produced the largest forward (horizontal) displacement at all the anatomical points. The horizontal position of all anatomical points increased linearly with load. CONCLUSION: There is evidence refuting the 'rule-of-thumb' to carry the backpack high on the back. Typical school backpacks should be positioned with the centre at waist or hip level. There is no evidence for the 10% body weight limit.

Non-steroidal anti-inflammatory drugs (NSAIDs): physiotherapists' use, knowledge and attitudes.

This paper reports on a survey regarding physiotherapists' knowledge, use and attitudes to non-steroidal anti-inflammatory drugs (NSAIDs), some of which have recently been re-scheduled to non-prescription dispensing. A written survey instrument was developed and administered to 750 physiotherapists in South Australia, Tasmania and the Australian Capital Territory (50% of the registered physiotherapists). Responses were received from 285 physiotherapists. The survey identified opportunities for patient misuse and misadventures with NSAIDs in conjunction with physiotherapy management. Differences in physiotherapist understanding of the dosage and actions of oral and topic administrations of NSAIDs were highlighted, as were the moral and ethical responsibilities of physiotherapists to patients considering taking NSAIDs. The study identified the need for regular professional updates on quality use of NSAIDs.

Lower back and elbow injuries in golf.

Golf injuries to the lower back and elbow are common problems in both the professional and amateur player, and any information regarding the successful treatment of these injuries has important implications for the medical practitioner. This paper presents the successful management and outcome of two case studies associated with low back pain and lateral epicondylitis in golf. Exercise therapy and conditioning has been shown to be an effective treatment modality for these two types of injury. In particular, a dynamic exercise programme which incorporates golf functional rehabilitation, is a modern and accepted method by both the patient and the clinician. Effective programmes need to be golf-specific to maintain the interest of the participant and yet at the same time they need to be able to accommodate other factors such as age, gender and the level of the golfer. Furthermore, it is critical that the clinical practitioner has a fundamental knowledge of normal swing mechanics and a working knowledge of the musculoskeletal requirements needed to swing a golf club. In the case of the lower back injury, evaluation was based on detailed computer tomography and centred on the conditioning of the transversus abdominis muscle. Although this muscle is not considered to be paraspinal, it has particularly important implications in the maintenance of spinal stability so that other more specific golf functioning exercises and rehabilitation can be performed. For the case study of lateral epicondylitis detailed evaluation and consideration of neuropathy was an important factor in the diagnostic process. In part, it was necessary to deviate from conventional treatment to produce an effective outcome. A comprehensive resistance-strength-training programme and golf functional 'hitting' programme was used to treat the problem. The conformity by the patient to complete the exercise regimen has been an issue of concern for clinicians managing and treating golf-related problems. Many golfers are 'fanatical' and unless they can see that by continuing the programme their injury will be overcome, it is difficult trying to restrict their time on the golf course. The two case studies described in this article highlight how an extensive and dynamic golf functional programme could be used as an effective method for managing and preventing golf injuries.

Providing evidence of good allied health care for the veteran population: development of a unique management system.

A unique management system was developed to enhance the quality of allied health care for the elderly. The management system is a multipronged framework of processes and outcomes, which address key stakeholder needs, and is based on best scientific evidence. Use of the management system provides efficiencies for funding bodies in data collection and monitoring service quality. It also confirms the professional integrity of the allied health service provider and underscores the importance of client-therapist partnership in determining appropriate health outcomes. Further testing is required to assess the relationship between use of the allied health management system and better quality service provision, cost containment, and consistently good client health outcomes.

On the constructs of quality physiotherapy.

The quality of physiotherapy services invites evaluation using a range of constructs. These must reflect the needs of different stakeholders and the different elements of the "package" of physiotherapy. Measurement of quality can consider organisation of the service, the way in which care is provided, the way in which information about care is recorded and used for evaluation purposes, and the outcome of care. A clear understanding of the elements of quality is essential for physiotherapists to be competitive by providing consistently effective services.

Recreational and sporting injury to the adolescent knee and ankle: Prevalence and causes.

This study describes the prevalence of adolescent ankle and knee injuries from participation in recreational and sporting activities. Data were collected over a one-week retrospective time frame from 3,538 subjects aged 11-12 years and 15-16 years from the Adelaide metropolitan region. Young people reported participating in 142 recreational activities and, overall, one injury was reported by every fourth subject and in every third activity. Knee and ankle injuries were the most prevalent, reflecting approximately 13 and 14 per cent respectively overall. The most commonly reported activities which had large numbers of knee and/or ankle injuries were investigated in this paper. There were significant differences in risk of ankle and knee injury within age and gender strata for different activities, although similar mechanisms and types of injury were found for both knees and ankles. Strategies to prevent adolescent lower limb sporting and recreational injury are discussed.
