The Effect of Somatosensory Cue on Postural Stability in Blinded Persons

Completed

• Conditions: Visual Impairment

• Registration Number: NCT00650676
• Lead Sponsor: Soroka University Medical Center

Brief Summary

Blind Adults that willing to participate in the study will be tested with well-established measuring techniques of Balance control using force plate in the movement and Rehabilitation Laboratory at Ben-Gurion University. An automated algorithm will be used to extract standardized stabilogram-diffusion parameters from each of the COP data sets collected during quiet standing. These parameters include diffusion coefficients, critical displacement, critical time and scaling exponents for both lateral and anterior-posterior sway directions (Collins \& De Luca, 1993). the subjects will be tested in 3 task conditions (eyes blindfolded, eyes blindfolded holding stick, eyes blindfolded holding a dog). Participants will be required to stand on the platform 10 times for 30 s For each trial, they will be instructed to sway as little as possible.
