Improving upper-limb and trunk kinematics by interactive gaming in individuals with chronic stroke: A single-blinded...

Area of Science:

• Neurorehabilitation
• Robotics and Virtual Reality in Medicine
• Biomechanics of Movement

Background:

• Commercial gaming systems are increasingly utilized in stroke rehabilitation.
• The impact of these systems on upper-limb recovery versus compensatory movements remains unclear.

Purpose of the Study:

• To compare interactive gaming (Nintendo Wii) with conventional therapy for upper-limb stroke rehabilitation.
• To assess effects on elbow extension (recovery) and forward trunk motion (compensation).
• To evaluate secondary outcomes including clinical assessments, pain, effort, and movement kinematics.

Main Methods:

• A single-centre randomized controlled trial comparing 12 sessions of Wii therapy to conventional therapy over 4 weeks.
• Electromagnetic and inertial sensors were used to measure elbow extension, trunk motion, and arm/trunk acceleration.
• Outcomes assessed at baseline and 4 weeks included clinical tests (Fugl-Meyer, Box and Block, ARAT, MAL, SIS) and kinematic data.

Main Results:

• No significant difference in the mean change of elbow extension angle or forward trunk position between Wii and conventional therapy groups.
• Both groups showed similar, small improvements in clinical scores.
• Arm acceleration during Wii sessions increased with training, but trunk acceleration did not.

Conclusions:

• Supervised upper-limb gaming therapy yielded comparable elbow extension recovery to conventional therapy.
• Gaming therapy did not increase compensatory trunk movement in chronic stroke survivors.
• Additional or more frequent sessions may be required for greater therapeutic benefits.
