Physical activity interventions are known to be effective in improving the physical and psychological complaints of breast cancer survivors.
To investigate the impact of a specific exercise training program on upper limb mobility and quality of life in breast cancer survivors.
The study included 55 women recruited at the Cancer Rehabilitation Centre in Florence after the completion of breast cancer treatment and rehabilitative physiotherapy. All participants underwent an 8-week specific exercise training to improve upper limb mobility function and quality of life. Anthropometric parameters were measured, and each subject underwent a battery of fitness tests to assess shoulder-arm mobility, range of motion, and back flexibility before and after specific exercise program. All participants filled out the Short Form-12 and numerical rating scale questionnaires to assess the quality of life and to quantify back and shoulder pain intensity.
The evaluation of shoulder-arm mobility and self-reported questionnaire data revealed a statistically significant improvement after completion of our specific exercise program.
An organized specific program of adapted physical activity can be effective in reducing the main adverse effects of surgery and oncological therapy, and may significantly improve shoulder-arm mobility and quality of life in breast cancer survivors.

Crossing moving obstacles requires different space-time adjustments compared with stationary obstacles. Our aim was to investigate gait spatial and temporal parameters in the approach and crossing phases of a moving obstacle. We hypothesized that obstacle speed affects gait parameters, which allow us to distinguish locomotor strategies. Ten young adults walked and stepped over an obstacle that crossed their way perpendicularly, under three obstacle conditions: control—stationary obstacle, slow (1.07m/s) and fast speed (1.71m/s) moving obstacles. Gait parameters were different between obstacle conditions, especially on the slow speed. In the fast condition, the participants adopted predictive strategies during the approach and crossing phases. In the slow condition, they used an anticipatory strategy in both phases. We conclude that obstacle speed affects the locomotor behavior and strategies were distinct in the obstacle avoidance phases.
