Muscle strength training, gait performance and physiotherapy after stroke.

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Hemiparesis following stroke leads to significant long-term disability, characterized by muscle weakness and impaired gait.
• Effective rehabilitation strategies are crucial for improving lower limb function and mobility in stroke survivors.

Purpose of the Study:

• To review the effects of lower limb progressive resistance training (PRT) on muscle strength, tone, gait, and participation after stroke.
• To evaluate the safety and efficacy of PRT as a rehabilitation intervention for stroke-induced hemiparesis.

Main Methods:

• Systematic review summarizing studies on lower limb progressive resistance training (PRT) with loads ≥70% of maximum strength.
• Analysis of PRT's impact on muscle strength, muscle tone, gait performance, and perceived participation.

Main Results:

• PRT is a safe and effective method for enhancing muscle strength post-stroke, with no adverse effects on muscle tone.
• Improvements in muscle strength through PRT positively correlate with enhanced gait performance and perceived participation.
• Strength training, including PRT, is recommended for stroke rehabilitation and can serve as effective fitness training for individuals with mild weakness.

Conclusions:

• Progressive resistance training (PRT) is a beneficial intervention for improving muscle strength, gait, and participation in stroke survivors.
• Further research is needed to optimize PRT timing, identify ideal patient candidates, and integrate it with other stroke therapies.
• PRT offers a promising avenue for enhancing functional recovery and reducing disability after stroke.
