The effect of a task-oriented intervention on arm function in people with stroke: a randomized controlled trial

Area of Science:

• Neurorehabilitation
• Physical Therapy
• Stroke Recovery

Background:

• Stroke frequently results in impaired arm function, impacting daily activities.
• Effective interventions are crucial for improving motor recovery and quality of life in stroke survivors.

Purpose of the Study:

• To evaluate the efficacy of a task-oriented intervention for enhancing arm function in individuals post-stroke.
• To assess the impact of functional task practice on manual dexterity and voluntary movement.

Main Methods:

• A two-centre, observer-blinded, randomized controlled trial was conducted.
• Ninety-one individuals within one year of stroke participated.
• The intervention group practiced functional tasks, while the control group engaged in walking tasks for six weeks.

Main Results:

• No significant difference in arm function was observed between the task-oriented intervention group and the control group on the Box and Block Test.
• Performance on secondary measures of arm function, including the Nine-Hole Peg Test and grip strength, also showed no meaningful changes.
• Baseline performance on the Box and Block Test was approximately 40% of age-predicted values for both groups.

Conclusions:

• A task-oriented intervention did not demonstrate efficacy in improving voluntary movement or manual dexterity of the affected arm in people with chronic stroke.
• Further research may be needed to explore alternative or modified task-oriented approaches for stroke rehabilitation.
