Mirror-Based Robotic Therapy for Ankle Recovery with a Serious Game: A Case Study with a Neurological Patient

Area of Science:

• Neuroscience
• Rehabilitation Engineering
• Robotics

Background:

• Neuromuscular disorders like foot drop significantly impair locomotor function and independence post-brain injury.
• Mirror-based robotic therapy (MRT) shows promise for upper limb rehabilitation but lacks validation for lower limb applications.
• Existing rehabilitation strategies for lower limb motor deficits require innovative approaches.

Purpose of the Study:

• To present an innovative visual and motor feedback strategy using serious games and MRT for lower limb rehabilitation.
• To validate a novel system with a healthy participant.
• To investigate the potential effects of this strategy in a short rehabilitation program for a neurologic patient.

Main Methods:

• Development of a serious game integrated with mirror-based robotic therapy (MRT) for lower limb motor feedback.
• Preliminary system validation conducted with a healthy participant.
• Application of the strategy in a short-term rehabilitation program for a neurologic patient with foot drop.

Main Results:

• The system demonstrated positive effects on active ankle plantarflexion range of motion and muscle activation after six sessions.
• The patient showed positive adaptation and engagement with the serious game during the rehabilitation program.
• Preliminary validation with a healthy participant confirmed system feasibility.

Conclusions:

• The proposed serious game and MRT strategy shows potential for improving lower limb function, specifically ankle mobility and muscle activation, in patients with neuromuscular disorders.
• Further refinement of the strategy is necessary to optimize the robotic experience and long-term therapeutic benefits.
• This approach represents a novel application of MRT and serious games for lower limb rehabilitation post-brain injury.
