Effect of Blood Flow Restriction Training on Quadriceps Muscle Architecture and Functional Abilities in Children With Hemiplegia
Sponsor: Cairo University
Summary
This study was done to investigate the effect of blood flow restriction in the lower limbs on: Strength of the quadriceps muscle, quadriceps muscle architecture (muscle thickness and pennation angle between muscle fibres), selective motor control of the lower limb in the affected limb, and gait parameters.

Interventions
the selected physical therapy program
The physical therapy program includes passive stretching exercises for the lower limb to enhance range of motion (ROM) in children with cerebral palsy (CP), transition training from sitting to standing to improve postural control, and core stability exercises to boost trunk endurance and gait. Reactive balance training aims to improve children's postural response organization, while various walking training methods, including treadmill and obstacle walking, focus on enhancing gait speed, balance, and postural stability. Overall, the program is designed to address specific impairments and activity limitations in children with hemiplegic CP.
Blood Flow Restriction training
This group will undergo a physical therapy program incorporating Blood Flow Restriction therapy on the upper thigh. The training will consist of one hour sessions, 2-3 times a week for 8 weeks. The load applied will be 20-40% of One-repetition maximum (1RM), with 5-10 minutes of restriction time per exercise set. Each session will include 4 sets, totaling 75 repetitions (30 × 15 × 15 × 15), along with reperfusion between sets. Pressure application will be 40-80% of arterial occlusion pressure (AOP), with rest periods of 30-60 seconds between sets. The restriction form will be continuous, with an execution speed of 1-2 seconds for each exercise, continuing until the planned repetitions are completed.
