Abstract

Background & Purpose: Background: Efficient walking requires the interaction of the three sensory systems for a good maintenance of the balance. In deaf people, lack of hearing input can harm for walking mechanics. The purpose of this study was to compare plantar pressure variables during walking with and without immediate use of textured insoles in deaf and healthy subjects. Methods: The design of the present study was self-controlled study. Fifteen deaf and 15 healty males volunteered to participate in this study. A foot scan system (sampling rate: 300Hz) was used for measuring plantar pressure variables during walking with and without textured insoles. Paired sample t-test was used for statistical analysis. Alpha level was set at p<0.05. Results: Results demonstrated that the medio-lateral (p=0.001, d=1.83) and the anterio-posterior (p=0.001, d=1.83) displacement of the center of pressure during walking with insoles was lower than that walking without insoles. First metatarsal peak plantar pressure (p=0.004, d=1.16) and force(p=0.032, d=1.01) during walking with insoles decreased respectively. There was significant differenses betweeen deaf and healthy pople in vertical loading rate (p=0.041). There was significant differenses betweeen deaf and healthy pople in peak plantar pressure in first (p=0.043), third (p=0.049), forth (p=0.012), fifth (p=0.011) metatarsals and medial part of calcaneos(p=0.0049),, during walking. Conclusions: Textured insoles improved medio-lateral and the anterio-posterior postural control during walking. Therefore, it could be recommended for deaf individuals. However, further study is warranted.
