Task-oriented progressive resistance strength training improves muscle strength and functional performance in...

Area of Science:

• Neurology
• Rehabilitation Medicine
• Physical Therapy

Background:

• Chronic stroke often leads to persistent lower extremity weakness and impaired functional mobility.
• Rehabilitation strategies aim to improve strength and function in stroke survivors.

Purpose of the Study:

• To evaluate the efficacy of task-oriented progressive resistance strength training (PRST) for enhancing lower extremity strength and functional performance in individuals with chronic stroke.

Main Methods:

• A single-blind, randomized controlled trial was conducted with 48 chronic stroke subjects.
• Participants were allocated to either an experimental group (4-week PRST) or a control group (no rehabilitation).
• Outcome measures included lower extremity muscle strength, gait parameters, and functional tests (e.g., 6-minute walk, Timed Up and Go).

Main Results:

• The experimental group demonstrated significant improvements in both strong and paretic side lower extremity muscle strength.
• Functional performance measures, including gait velocity and walk tests, significantly improved in the PRST group.
• Significant positive associations were observed between strength gains and functional improvements.

Conclusions:

• Task-oriented progressive resistance strength training is an effective intervention for improving lower extremity muscle strength in chronic stroke patients.
• The observed strength gains translate into meaningful improvements in functional abilities, supporting its use in stroke rehabilitation.
