Reliability of sitting posture between physical therapist video-based evaluation and SMART IMU system using rapid upper limb assessment (RULA).

This study investigates the ergonomic assessment of sitting postures and the potential for work-related musculoskeletal disorders (WMSDs) in office environments by comparing traditional physical therapist evaluations with Inertial Measurement Unit (IMU) technology by determining the reliability and accuracy of sitting posture assessment using the rapid upper limb assessment (RULA) method. In this experiment, neck and body angle data is collected from twenty participants while sitting and working. The study aims to capture and compare the neck and trunk posture score based RULA protocol system to evaluate ergonomic risks.

Development of low-cost pressure mapping device to evaluate force distribution for seat cushion modification.

This study aimed to determine the reliability and concurrent validity of a low-cost pressure mapping system (Smart mat) and reference standard pressure mapping (MatScan). Thirty healthy volunteers aged 29.57 ± 4.

Integration of force and IMU sensors for developing low-cost portable gait measurement system in lower extremities.

Gait analysis is the method to accumulate walking data. It is useful in diagnosing diseases, follow-up of symptoms, and rehabilitation post-treatment. Several techniques have been developed to assess human gait.

Effectiveness of a Simple Auditory Feedback Insole (Sim-Insole) for Touchdown Weight-Bearing Training in At-Risk Volunteers with Poor Compliance: A Crossover Study.

Introduction: Recent studies have shown that biofeedback devices are effective for weight-bearing (WB) training. However, these devices have limitations due to high costs and inadequate evidence of their effectiveness among poor-compliance individuals. This study aimed to assess WB compliance after touchdown weight-bearing (TDWB) training by the standard bathroom scale (BS) method and to evaluate the efficacy of our innovative simple auditory feedback device (Sim-Insole).

Reliability and Correlation of the Force-PRO Device and Computer-Assisted Navigation System for Measurement of Acetabular Cup Position in Total Hip Arthroplasty.

Introduction: Acetabular cup malposition is very common in total hip arthroplasty (THA) and is significantly associated with many serious postoperative complications, such as dislocation, wear and loosening, and decreased range of motion. To improve the accuracy of intraoperative assessment, we recently developed an innovative sensor-based navigation system (Force-PRO device) using an inertial measurement unit and a 3D-printed liner for acetabular cup measurement, and aimed to evaluate its reliability and correlate its accuracy with that of a computer-assisted navigation system (CANS).

Design: Method-comparison study between the Force-PRO device and a standard CANS in a 1:1 pelvic bone model.

Innovative Force-PRO device to measure force and implant position in total hip arthroplasty.

Total hip arthroplasty (THA) is the appropriate treatment for hip pain, dislocation, and dysfunction. THA refers to surgery to replace a hip implant, which is an effective way to recover normal hip function. The design of an implant imitates hip functions and allows bone growth in the implant area.
