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.

Detailed Description

The G-Walk determines spatiotemporal parameters as well as pelvic rotations during gait and allows objective and precise analysis of movements with its wearable inertial sensor. It also enables 3D kinematic analysis of the pelvis, providing a functional analysis of disorders in gait caused by neuromuscular diseases The device is placed on an elastic belt and worn on the waist of the person being evaluated, with the center of the device at the fifth lumbar vertebrae. To ensure correct placement of the device, the L4-L5 intervertebral space was palpated via the posterior superior iliac spines.

After the accelerometer was placed, the participants were asked to walk calmly at normal speed, on a 10 m track, and to return to the starting position.

The values and gait characteristics of acceleration in the anteroposterior and mediolateral axes were transferred to the computer software program.

The tilt of the pelvis in the sagittal plane in the flexion-extension direction, the oblique displacement in the coronal plane, the angles of the rotation of movement in the transverse plane and the symmetry values of the right and left sides are obtained. While the symmetry index ranges from 0 to 100, a value closer to 100 indicates that the gait is more symmetrical Following gait assessment, Countermovement jump, static squat jump and Countermovement jump with arms thrust was measured using the device.

Conditions

Healthy; Adult

• Study Time Perspective: PROSPECTIVE

Study Groups

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.

The G-Walk sensor system (G-Walk)

Intervention Type: 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.
