Purpose: To establish the feasibility and effectiveness of a community-based exercise programme for ambulatory patients with stroke discharged from rehabilitation.
Method: Eighteen participants were recruited 3-12 months after onset of first stroke. Using a time series experimental design, the group completed a baseline period of 4 weeks (A1), a group exercise programme of low-intensity progressive resistive exercise and functional tasks for lower limb muscles (B) and repeat assessment after cessation of exercise (A2). Fitness instructors delivered sessions at Leisure Centres twice weekly for 14 weeks with physiotherapy support and the minimum attendance requirement was 16 sessions. Measures included muscle strength, gait velocity, Berg Balance Scale and Nottingham Extended Activities of Daily Living.
Results: Lower limb muscle strength improved after training (ANOVA, p < 0.02). Paretic knee extension strength increased from 43.4 + or - 5.9 to 60.4 + or - 6.8 Nm after 16 exercise sessions. Walking velocity increased significantly (ANOVA, p < 0.001), from 0.54 + or - 0.07 to 0.75 + or - 0.08 m/s (t = -3.31, p < 0.01). Balance and everyday function were also significantly improved (p < 0.003). There were marked individual variation in the response to training, and those who completed additional training did not show benefit.
Conclusions: This community-based exercise programme was feasible and delivered positive improvements in physical function for participants. Further issues raised for investigation include the individual response to training and the benefits of extended training.

Physical activity is crucial for children's physical, cognitive, and social development, reducing the risk of non-communicable diseases and improving overall well-being. A major legacy of extremely preterm delivery is respiratory limitation with reduced lung function and decreased exercise capacity which can be further exacerbated by inactivity and deconditioning. Strategies to increase incidental physical activities in early childhood and participation in sport and more formal exercise programmes in middle childhood have the potential to optimize cardiopulmonary function, improve quality of life, and foster social interactions in childhood and beyond, thereby providing benefits that extend far beyond the physical domain.

Objective: This study aimed to validate the ultrasound speckle tracking (UST) algorithm, determine the optimal probe location by comparing normalized cross-correlation (NCC) values of muscle displacement at two locations (proximal vs. middle) of the biceps femoris long head (BFlh) using the UST, and investigate the effects of Nordic hamstring curl exercise (NHE) training on BFlh displacement.
Methods: UST efficacy was verified with ex vivo uniaxial testing of porcine leg muscles.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta band during a dynamic bimanual, visuomotor pinch force task.
