The effects of task-oriented mental practice on upper limb function and coordination in chronic stroke...

Area of Science:

• Neurorehabilitation
• Motor control and learning
• Stroke recovery

Background:

• Chronic stroke often results in persistent upper limb motor deficits.
• Restoring upper limb function is crucial for independence and quality of life after stroke.
• Exploring novel therapeutic strategies like mental practice is essential for enhancing rehabilitation outcomes.

Purpose of the Study:

• To investigate the efficacy of task-oriented mental practice (TOMP) on upper limb function and coordination in chronic stroke survivors.
• To compare the effects of TOMP with traditional task-oriented training.

Main Methods:

• A randomized experimental design study involving 34 chronic stroke patients.
• Patients were divided into an experimental group (EG) receiving TOMP and a control group (CG) receiving task-oriented training.
• Upper extremity function assessed using the Fugl-Meyer Assessment (FMA), and coordination measured by co-coordination ratio (CCR) using BTS FreeEMG 300.

Main Results:

• The EG demonstrated significant improvements across all FMA items, while the CG showed improvements only in shoulder items (p < 0.05).
• Significant differences were found in the total FMA score between the groups (p < 0.05).
• The EG exhibited positive changes in CCR values for most items, whereas the CG showed negative changes.

Conclusions:

• Task-oriented mental practice (TOMP) is an effective intervention for improving upper limb motor function and coordination in chronic stroke patients.
• TOMP offers superior benefits compared to conventional task-oriented training for upper limb recovery post-stroke.
