Gait abnormalities can significantly impact a person’s mobility and overall quality of life. Rehabilitation is crucial for individuals with such conditions to regain their independence and improve their gait patterns. This paper introduces a groundbreaking sensing and feedback system designed for personal gait rehabilitation. The system utilizes wireless transmission of ambulation data, enabling real-time sensory feedback for assistive healthcare. By leveraging an integrated force-sensing insole and a smartphone application, this innovative solution aims to enhance gait rehabilitation outcomes. Through comprehensive experiments and statistical analysis, the effectiveness, reliability, and repeatability of the system are evaluated.

Design and Implementation

The core component of the sensing and feedback system is the integrated force-sensing insole. This insole incorporates embedded force sensitive resistors (FSRs) that capture real-time gait data. A microprocessor is employed to sample the FSRs and transmit the collected data wirelessly to an Android smartphone. The smartphone application is responsible for processing the data and providing sensory feedback to the user. This combination of hardware and software enables individuals to receive immediate information about their gait performance, facilitating self-awareness and self-correction during the rehabilitation process.

Verification of Accurate Gait Data

To validate the accuracy of the device in capturing gait data, extensive experiments were conducted. The subjects wore the sensing insoles while performing various walking tasks, and the collected data were compared to reference measurements obtained from motion capture systems. The results demonstrated that the system consistently captured accurate gait data, indicating its reliability as a tool for monitoring and assessing gait abnormalities.

Influencing Gait Through Sensory Feedback

The ability of the feedback system to influence the gait of the user was a crucial aspect evaluated in this study. Different sensory feedback methods were explored to determine their efficacy in modulating the gait patterns of the study subjects. The feedback methods included visual cues displayed on the smartphone screen, auditory cues, and haptic vibrations triggered by the insole. Through iterative testing and analysis, the research team identified the most effective feedback approach, which significantly influenced the gait of the subjects.

Independent Rehabilitation Support

One notable advantage of this sensing and feedback system is its potential to provide independent rehabilitation support without the need for direct supervision by a rehabilitation specialist. The real-time feedback enables individuals to actively engage in their rehabilitation process and make immediate adjustments to their gait. This autonomy empowers users to take control of their recovery, promoting self-confidence and motivation throughout the rehabilitation journey.

Reliability and Repeatability Analysis

To establish the reliability and repeatability of the system, a statistical analysis was conducted. The consistency of gait measurements and the correlation between successive trials were examined. The results confirmed the system’s reliability, demonstrating its ability to consistently produce accurate and repeatable gait data. This statistical validation strengthens the foundation of the feedback system as a reliable and effective tool for clinical rehabilitation purposes.

Novelty, Affordability and Effectiveness

Based on the results obtained from the experiments and statistical analysis, the presented sensing and feedback system is established as a novel, inexpensive, and effective candidate for clinical rehabilitation of individuals with gait abnormalities. The wireless transmission of ambulation data, combined with real-time sensory feedback, offers a user-friendly and accessible solution for gait rehabilitation. With its potential to enhance independent rehabilitation and improve gait patterns, this system has the ability to positively impact the lives of numerous individuals facing gait-related challenges.
