Effectiveness of scoliosis-specific exercises for adolescent idiopathic scoliosis compared with other non-surgical interventions: a systematic review and meta-analysis.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To assess the effectiveness of scoliosis-specific exercises (SSE) on adolescent idiopathic scoliosis (AIS) compared with other non-surgical interventions. BACKGROUND: AIS is a complex deformity of the spine that develops between the age of 10years and skeletal maturity. SSE are prescribed to patients to reduce or slow curve progression, although their effectiveness is unknown. METHODS: Electronic databases were searched for relevant studies. Randomised controlled trials were eligible if they compared SSE with non-surgical interventions for individuals with AIS. Three authors independently extracted data, evaluated methodological quality and assessed the quality of evidence. Meta-analysis was performed where possible; otherwise, descriptive syntheses are reported. RESULTS: Nine randomised controlled trials were included. Four had a high risk of bias, three had an unclear risk and two had a low risk. Very-low-quality evidence indicated that SSE improved some measures of spinal deformity, function, pain and overall health-related quality of life (HRQoL). Very-low-quality evidence suggested that SSE had no effect on self-image and mental health. Very-low-quality evidence showed that bracing was more effective than SSE on measures of spinal deformity. However, SSE showed greater improvements in function, HRQoL, self-image, mental health and patient satisfaction with treatment. No differences were found for pain or trunk rotation. CONCLUSIONS: SSE may be effective for improving measures of spinal deformity for people with AIS, but the evidence is of very low quality. Future studies should evaluate relevant clinical measures and cost-effectiveness using rigorous methods and reporting standards.

Development and delivery of an exercise intervention for rheumatoid arthritis: strengthening and stretching for rheumatoid arthritis of the hand (SARAH) trial.

This paper describes the development and implementation of a hand exercise intervention for rheumatoid arthritis (RA) as part of a large multi-centred randomised controlled trial in a U.K. National Health Service (NHS) setting. Participants are eligible if diagnosed with RA according to American College of Rheumatology criteria, have a history of disease activity, functional deficit or impairment in the hand and/or wrist, and have been on a stable medication regime for at least 3 months. The intervention development was informed by the current evidence base, published guidelines, clinician and expert opinion, and a pilot study. The exercise programme targets known, potentially modifiable physical impairments of the hand with 5 exercise sessions and a home exercise component over a 12 week period. The intervention will be provided to 240 participants along with usual care. A further 240 will receive usual care only as part of the control arm. Specific details of the treatments delivered are described. [ISRCTN no: 89936343].

Trunk proprioception: enhancement through lumbar bracing.

OBJECTIVES: To examine the effects of a neoprene lumbar brace on the proprioceptive ability of subjects without pathology and to determine whether those with poorer proprioception were more affected by the brace. STUDY DESIGN: Randomized 2 x 2 Latin square cross-over design. SETTING: Laboratory in an educational institution. SUBJECTS: Forty asymptomatic subjects matched by gender, age, weight, and height. METHOD: Blindfolded subjects performed a position matching task in which they flexed the trunk in the sagittal plane. Six positions across the range of motion were examined. Angular data were recorded by a lumbar motion monitor secured by straps to the subject's trunk. MAIN OUTCOME MEASURE: Absolute, constant, and variable errors in braced and unbraced conditions. RESULTS: The mean absolute, constant, and variable errors were 3.6 degrees, .45 degrees, and 4.4 degrees, respectively. Absolute, constant, and variable errors were significantly decreased when wearing a brace. However, the magnitude of the decreases were small (<1.0 degrees) for all errors when wearing a brace. The high error group's absolute error improved significantly (p < .05), from 6.0 degrees when unbraced to 4.0 degrees when braced. In contrast, absolute error measurements for subjects in the low error group were unchanged, with an error of 2.0 degrees when unbraced and 2.3 degrees when braced. CONCLUSIONS: The findings suggest that a neoprene lumbar brace improves the somatosensory information received by the central nervous system and results in less error in trunk positioning. Persons with less ability to match trunk position will benefit more from wearing a neoprene brace than will those who are already adept at the task.
