Reinforced Feedback in Virtual Environment for Plantar Flexor Poststroke Spasticity Reduction and Gait Function...

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Movement Science

Background:

• Ankle spasticity is a common impairment following stroke, significantly impacting functional mobility.
• Restoring motor control and gait is a primary goal in post-stroke rehabilitation.

Purpose of the Study:

• To evaluate the efficacy of traditional rehabilitation (TR) combined with a reinforced feedback virtual environment (RFVE) in reducing ankle spasticity.
• To assess the impact of this combined therapy on gait function in stroke survivors.

Main Methods:

• A study involving 10 hemiparetic patients assessed using the Modified Ashworth Scale (MAS), Functional Ambulatory Category (FAC), and Functional Independence Measure (FIM).
• Intervention comprised 1 hour/day of TR and 1 hour/day of RFVE for 3 weeks (15 sessions).

Main Results:

• Significant improvements were observed in MAS (spasticity) and FAC (gait function) scores (P < 0.05).
• Functional Independence Measure (FIM) scores showed a trend towards improvement but did not reach statistical significance (P=0.066).
• Earlier initiation of treatment correlated with greater improvements in FAC scores.

Conclusions:

• The combination of TR and RFVE demonstrates promising results for reducing spasticity and enhancing gait in stroke patients.
• Early intervention is crucial, and larger studies with diverse assessment tools are warranted.
