Simple Explanation

Balance control is crucial for recovery after events like stroke or spinal cord injuries. Current methods for rehabilitation don't fully use available technologies. This paper introduces a new system for balance training. It uses low-cost devices like the Nintendo Wii Balance Board and Microsoft Kinect. The system also includes a special electrical stimulator. This stimulator uses muscle synergies to help people move more naturally.

Not specified

Participants

6 healthy subjects (3 men and 3 women)

Evidence Level

Technical validation

Key Findings

1
The platform combines a CDP device with low-cost interfaces, such as the Nintendo Wii Balance Board and the Microsoft Kinect.
2
It integrates a custom electrical stimulator that uses the concept of muscle synergies to promote natural interaction.
3
Technical validation of the platform was performed using mediolateral and anteroposterior sways as basic balance training therapies.

Research Summary

This paper presents a novel balance training platform which combines a CDP device made from low-cost interfaces, such as the Nintendo Wii Balance Board and the Microsoft Kinect. In addition, it integrates a custom electrical stimulator that uses the concept of muscle synergies to promote natural interaction. Results include the technical validation of the platform using mediolateral and anteroposterior sways as basic balance training therapies.

Practical Implications

Low-Cost Rehabilitation Tool

The platform offers a cost-effective solution for balance rehabilitation using commercially available components.

Synergy-Based Therapy

It explores the potential of muscle synergies in improving neural plasticity and adapting to subject-specific kinematic constraints.

Multimodal Interface

The system provides a flexible tool for assessment and training of balance control using multimodal feedback mechanisms (kinematic, CoP, auditory, visual, and electrical signals).

Study Limitations

1
The system relies on non-real-time elements, affecting timing and synchronization performance.
2
The synergistic EMG profiles are generated in an open-loop fashion.
3
Clinical trials are needed to define the effectiveness of the platform in neurologically injured people.
