MEASURING GAIT TO DETECT IMPAIRMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18085974 titled 'MEASURING GAIT TO DETECT IMPAIRMENT

The patent application describes a method for detecting impairment using a vibration fingerprint that characterizes gait dynamics.

• Measurements of a being's gait are received from a sensor and converted into a time series of observations for each frequency bin in a set of frequency bins.
• Time series of residuals are generated by subtracting the time series of observations from a time series of references for each range of the set.
• An impairment metric is generated based on the time series of residuals and compared to a threshold for impairment.
• If the impairment metric satisfies the threshold, the being is indicated to be impaired.

Potential Applications: - Medical diagnostics for detecting gait-related impairments - Rehabilitation monitoring for tracking progress in recovering from injuries or surgeries - Sports performance analysis for assessing gait efficiency and technique

Problems Solved: - Early detection of impairments that may affect mobility and quality of life - Objective assessment of gait dynamics for personalized treatment plans - Real-time monitoring of changes in gait patterns for timely interventions

Benefits: - Improved accuracy in detecting impairments compared to traditional methods - Non-invasive and convenient way to assess gait dynamics - Enables proactive management of health conditions related to gait abnormalities

Commercial Applications: Title: "Gait Impairment Detection System for Healthcare and Sports Industries" This technology can be utilized in healthcare facilities, sports clinics, and research institutions for diagnostics, monitoring, and performance analysis purposes. It has the potential to enhance patient care, optimize rehabilitation programs, and improve athletic training strategies.

Questions about Gait Impairment Detection System: 1. How does this technology compare to existing methods for detecting gait impairments? 2. What are the potential limitations of using a vibration fingerprint for characterizing gait dynamics?

Original Abstract Submitted

Systems, methods, and other embodiments associated with detecting impairment using a vibration fingerprint that characterizes gait dynamics are described. An example method includes receiving measurements of a gait of a being from a sensor. The measurements of the gait are converted into a time series of observations for each frequency bin in a set of frequency bins. A time series of residuals is generated for each range of the set by pointwise subtraction between the time series of observations and a time series of references for each range of the set. An impairment metric is generated based on the time series of residuals. The impairment metric is compared to a threshold for the impairment. In response to the impairment metric satisfying the threshold, the being is indicated to be impaired.
