Systematic review with meta-analysis of randomised trials. Adults participating in an inpatient rehabilitation program. Additional rehabilitation provided after hours (evening or weekend). Function was measured with tests such as the Motor Assessment Scale, 10-m walk test, the Timed Up and Go test, and Berg Balance Scale. Performance on activities of daily living was measured with the Barthel index or the Functional Independence Measure. Length of stay was measured in days. Physical activity levels were measured as number of steps or time spent upright. Standardised mean differences (SMD) or mean differences (MD) were used to combine these outcomes. Adverse events were summarised using relative risks (RR). Study quality was assessed using PEDro scores. Seven trials were included...

The effects of reach distance and type of task on the functional relationship between the trunk, ... more The effects of reach distance and type of task on the functional relationship between the trunk, upper limb segments and the lower limbs during self-paced reaching in sitting were examined. Two-dimensional kinematic, kinetic and electromyography (EMG) data were collected as six healthy subjects reached forward under three distance (60, 100, 140% arm's length) and two task (reaching to press a switch, reaching to grasp a glass) conditions. The results demonstrate that type of task affected primarily the temporal aspects of coordination, with the grasp task taking consistently longer than the press task. In contrast, reach distance affected both the spatio-temporal aspects of coordination between the trunk and arm segments and the active contribution of the lower limbs. As reach distance increased, the magnitude of trunk and upper-arm segmental motion increased, whereas forearm segmental motion decreased. However, at each reach distance the path of the hand was relatively straight and there was remarkable consistency in the relationship between trunk and arm segments both within and between subjects suggesting that despite the presence of redundant degrees of freedom, the individual uses a parsimonious coordinative pattern. The vertical ground reaction force (GRF) and EMG data demonstrated that the lower limbs actively contributed to support the body mass when the object was located at 140% arm's length.

We conducted a systematic review to identify any theories, models, frameworks, influencing factors or interventions for sustaining fall prevention programs in the community. Peer-reviewed publications describing, investigating, or evaluating program sustainability were accessed. A narrative review was conducted to compare and synthesize study findings. Nineteen publications were included. Three conceptual frameworks were identified describing how programs may be better sustained. While ongoing financial support and the participation of older people were commonly reported influences, other factors specific to the type of program and setting were also reported. Planning, training, and collaboration between program stakeholders may facilitate sustainable programs. Organizations can use these findings when planning for sustainable programs. However more robust empirical studies are needed to confirm the value of conceptual f...

Subgroup analysis of a randomised trial: the AMBULATE trial. 68 people with stroke living in the community. The experimental group received 30 minutes of treadmill and overground walking, three times a week for four months; the control group received no intervention. The primary outcome was walking distance covered during the six-minute walk test. Other outcomes were comfortable and fast walking speed and health status. At four months, in the subgroup of participants with a baseline comfortable walking speed of > 0.4m/s, treadmill training produced an extra distance of 72m (95% CI 23 to 121) and an increased comfortable speed of 0.16m/s (95% CI 0.00 to 0.32), compared with the subgroup with a speed of ≤0.4m/s. There was also a trend towards an extra fast speed of 0.17m/s (95% CI -0.04 to 0.36). There was no extra e...

To investigate the cost-effectiveness of a 12-month home-exercise program for older adults after hospitalization. An economic evaluation was conducted alongside a randomized controlled trial. The analysis was conducted from the health and community service provider perspective. A total of 340 people aged 60 years and older, with a recent hospital admission, were randomized into exercise and usual care control groups. Incremental costs per extra person showing improvement in mobility performance (using the Short Physical Performance Battery), per person indicating improvement in health (self-reported using a 3-point Likert scale) and per quality-adjusted life year (QALY) gained (utility measured using the EQ-5D) were estimated. Uncertainty was represented using cost-effectiveness acceptability curves. Subgroup analyses for participants with better cog...

Design: A nonrandomized ABA trial. Setting: Sydney school. Subjects: Eight children with cerebral palsy, aged 4-8 years, seven with diagnosis of spastic diplegia, one of spastic/ataxic quadriplegia. Intervention: Four weeks of after-school exercise class, conducted for one hour twice weekly as group circuit training. Each work station was set up for intensive repetitive practice of an exercise. Children moved between stations, practising functionally based exercises including treadmill walking, step-ups, sit-to-stands and leg presses. Main outcome measures: Baseline test obtained two weeks before training, a pre-test immediately before and a post-test following training, with follow-up eight weeks later. Lower limb muscle strength was tested by dynamometry and Lateral Step-up Test; functional performance by Motor Assessment Scale (Sit-to-Stand), minimum chair height test, timed 10-m test, and 2-minute walk test. Results: Isometric strength improved pre-to post-training by a mean of 47% (SD 16) and functional strength, on Lateral Step-up Test, by 150% (SD 15). Children walked faster over 10 m, with longer strides, improvements of 22% and 38% respectively. Sit-to-stand performance had improved, with a reduction of seat height from 27 (SD 15) to 17 (SD 11) cm. Eight weeks following cessation of training all improvements had been maintained. Conclusions: A short programme of task-speci c strengthening exercise and training for children with cerebral palsy, run as a group circuit class, resulted in improved strength and functional performance that was maintained over time.

There is evidence that disability severity and fall rates can be reduced by welldesigned exercise interventions. However, the potential for exercise to have these benefits in older people who have spent time in hospital has not been established. This randomised controlled trial will investigate the effects of a home-based exercise program on disability and falls among people who have had recent hospital stays. The cost-effectiveness of the exercise program from the health and community service provider's perspective will be established. In addition, predictors for adherence with the exercise program will be determined.

The study aimed to investigate the effects of a home-based exercise program on falls and mobility among people recently discharged from hospital. This randomised controlled trial (ACTRN12607000563460) was conducted among 340 older people. Intervention group participants (n = 171) were asked to exercise at home for 15-20 minutes up to 6 times weekly for 12 months. The control group (n = 169) received usual care. Primary outcomes were rate of falls (assessed over 12 months using monthly calendars), performance-based mobility (Lower Extremity Summary Performance Score, range 0-3, at baseline and 12 months, assessor unaware of group allocation) and self-reported ease of mobility task performance (range 0-40, assessed with 12 monthly questionaries). Participants had an average age of 81.2 years (SD 8.0) and 70% had fallen in the past year. Complete prima...
