The Effect of Robot-Mediated Virtual Reality Gaming on Upper Limb Spasticity Poststroke: A Randomized-Controlled...

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Virtual Reality Applications

Background:

• Stroke frequently leads to upper limb motor disability, characterized by spasticity and impaired function.
• Effective spasticity management is crucial for accelerating motor recovery post-stroke.

Purpose of the Study:

• To evaluate the impact of robot-mediated virtual reality gaming on upper limb spasticity and motor function in chronic stroke patients.
• To compare the efficacy of conventional physiotherapy combined with VR gaming against conventional physiotherapy alone.

Main Methods:

• A randomized controlled trial involving 40 Saudi individuals with chronic stroke.
• The experimental group received conventional physiotherapy plus robot-mediated virtual reality gaming.
• The control group received only conventional physiotherapy. Outcome measures included ARAT, WMFT, MAS, AROM, and HGS, assessed at baseline and post-treatment.

Main Results:

• The experimental group demonstrated superior improvements in shoulder abduction AROM, elbow supination AROM, wrist extension AROM, WMFT-Time, HGS, ARAT, WMFT, and MAS compared to the control group.
• Both groups showed significant improvements across most measures, with the exception of wrist flexor MAS in the control group.

Conclusions:

• Robot-mediated virtual reality gaming is an effective intervention for reducing spasticity and enhancing upper limb motor function in chronic stroke survivors.
• This technology offers a promising adjunct to conventional physiotherapy for stroke rehabilitation.
