Usability evaluation of a kinematics focused Kinect therapy program for individuals with stroke

Area of Science:

• Rehabilitation science
• Game-based therapy
• Neuroplasticity

Background:

• Stroke survivors benefit from increased arm use for functional recovery.
• Limited long-term therapy access and low home exercise compliance hinder post-stroke recovery.
• Rehabilitation gaming shows potential but lacks addressed therapeutic method, safety, and usability for home use.

Purpose of the Study:

• To evaluate the usability of a game-based home therapy program, Home Arm Movement Stroke Training Environment (HAMSTER).
• To assess HAMSTER's effectiveness in retraining normal arm kinematics and preventing compensatory strategies post-stroke.

Main Methods:

• Developed Kinect games with specific considerations for stroke patients and normal movement kinematics.
• Conducted focused interviews with ten individuals post-stroke.
• One individual with chronic stroke completed one month of independent HAMSTER home use.

Main Results:

• Focused interviews highlighted the need for motivating upper extremity home interventions.
• Usability testing demonstrated that individuals with stroke could interact with kinematics-focused Kinect games quickly.
• The single-participant home use trial showed good compliance and improvements in all clinical outcome measures.

Conclusions:

• Kinematic-focused home gaming interventions like HAMSTER warrant further investigation.
• HAMSTER may reduce compensatory strategies during home exercise.
• This approach could supplement conventional care, improving exercise compliance and upper extremity function after stroke.
