Brief Summary

Gait analysis is an effective tool used for a variety of purposes, including assessing neurological diseases, risk of falling, orthopedic disability and progress during rehabilitation.The analysis of gait and jump performance must be applicable in a clinical setting. Thus; it needs to be easy to apply in a variety of life situations.The measurements should be reproducible, stable, accurate, capable of distinguishing between normal and abnormal conditions, and cost-effective. Jump measures can predict injury risks, serve as talent identification, and replicate explosive competitive activities of athletes. Furthermore, the performance in vertical jumping can be associated with neuromuscular fatigue.The purpose of this study was to confirm the test-retest reliability of the G-walk wearable sensor system for gait and jump parameters in healthy adults.

Outcome Measures

Primary Outcomes (2)

• Gait Analysis

  Gait parameters will be assessed via the G-Walk on two separate occasions. The G-Walk is a device that is worn on the waist via an elastic belt. The G-Walk is built with a triaxial accelerometer 16 bit/axes with multiple sensitivity, a triaxial magnetometer 13 bit and a triaxial gyroscope 16 bit/axes with multiple sensitivity. This hardware is capable of acquiring and transmitting data to a computer through a Bluetooth connection and at the end of each analysis an automatic report containing the gait assessment results is ready to be analyzed. Gait symmetry values of the right and left sides are obtained within this report. While the symmetry index ranges from 0 to 100, a value closer to 100 indicates that the gait is more symmetrical.

  Reliability of the G-Walk in 7 days

• Jump performance

  The jump tests protocols included; counter movement jump , squat jump and counter movement jump with arms thrust. At the end of the jump tests, all kinematic parameters concerning the evaluated jump were provided by the software. T Each participant performed a session of three trials for each of the assessed jumps. The jump with the maximum height was accepted for analysis.

Health Adults

Forty-nine healthy participants (30 females, 19 males) completed the test-retest protocol with 7 days between tests. Participants were; 23,58±2,65 years of age, 62,9±10,08 kg of weight and 168,76±8,31 cm of height. Participants included in the study did not have any musculoskeletal, neurological or other pathology potentially affecting their gait and jump performance.

Device: The G-Walk sensor system (G-Walk)

Interventions

The G-Walk sensor system (G-Walk) DEVICE

The G-Walk is a wireless sensor device which is placed on an elastic belt and worn on the waist of the person being evaluated. The device is placed with the center of the device at the fifth lumbar vertebrae and the patient is completely free to walk, run and jump wearing this device. The gait and jump performance of the participants was assessed with the participants wearing this device two times to investigate the test-retest reliability. The second being 7 days after the first.
