Effectiveness of modified constraint-induced movement therapy on upper limb function in stroke subjects

Area of Science:

• Neurorehabilitation
• Physical Therapy
• Stroke Recovery

Background:

• Over 50% of stroke survivors experience motor disabilities, particularly in upper limb function.
• Constraint-Induced Movement Therapy (CIMT) is effective but faces clinician apprehension due to practicality and resource concerns.
• A modified CIMT (m-CIMT) was developed, focusing on massed training of the affected arm without restricting the intact limb.

Purpose of the Study:

• To evaluate the effectiveness of the modified Constraint-Induced Movement Therapy (m-CIMT) for stroke patients.
• To assess if m-CIMT can improve upper extremity motor function post-stroke.
• To offer a potentially more practical alternative to traditional CIMT.

Main Methods:

• A randomized controlled trial involving 30 stroke patients.
• Patients were assigned to either the m-CIMT group (n=13) or a control group (n=17).
• The m-CIMT group underwent a 2-week intensive training program, with outcomes measured by the Wolf Motor Function Test (WMFT).

Main Results:

• Significant improvements (p<0.05) were observed in the m-CIMT group after just 2 weeks.
• Specific improvements noted in WMFT elements: Extend elbow with weight, Lift pencil, Stack checkers, Flip cards, Turn key in lock, and Lift basket.
• These results indicate rapid functional gains in the affected upper extremity.

Conclusions:

• The developed m-CIMT is a beneficial intervention for enhancing upper extremity function in stroke survivors.
• The study demonstrates the efficacy of m-CIMT in improving specific motor tasks.
• m-CIMT presents a viable and effective option for stroke rehabilitation.
