Lower-extremity constraint-induced movement therapy improved motor function, mobility, and walking after stroke.

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Physical Therapy

Background:

• Regaining walking ability is crucial for stroke survivors' independence and quality of life.
• Constraint-induced movement therapy (CIMT) is effective for upper extremity recovery, but its impact on lower extremity function post-stroke requires further investigation.

Purpose of the Study:

• To evaluate the effectiveness of intensive lower extremity constraint-induced movement therapy (LE-CIMT) on motor function, functional mobility, and walking ability in stroke patients.
• To determine if patient characteristics (age, gender, stroke type, affected side, time since stroke) influence LE-CIMT outcomes.

Main Methods:

• A longitudinal cohort study involving 147 sub-acute or chronic stroke patients.
• Patients underwent 2 weeks of intensive LE-CIMT (6 hours/day).
• Functional outcomes (Fugl-Meyer Assessment, Timed Up and Go, 10-Meter Walk Test, 6-Minute Walk Test) were assessed pre-intervention, post-intervention, and at 3-month follow-up.

Main Results:

• Statistically significant improvements were observed in all assessed functional outcomes immediately after LE-CIMT and were sustained at 3 months.
• Patients treated within 6 months of stroke onset showed greater improvements in the 10-Meter Walk Test compared to those treated later.
• Age, gender, stroke type, and affected side did not significantly impact 10-Meter Walk Test results.

Conclusions:

• High-intensity LE-CIMT effectively improves motor function, functional mobility, and walking ability in stroke patients during sub-acute and chronic phases.
• LE-CIMT presents a feasible and beneficial treatment option for outpatient settings to enhance post-stroke walking recovery.
• Further research with robust designs is recommended to fully elucidate LE-CIMT's efficacy.
