Erişkin Kas Hastalarında Oturmadan Ayağa Kalkma Aktivitesinin Çevresel, Biyomekanik Faktörler ve Kas Aktivasyonu Açısından İncelenmesi

Abstract

This study was planned to investigate sit to stand activity at adult patients with muscle disease in terms of environmental factors (seat height, seat hardness etc.), muscle strength, muscle activation, biomechanical factors and comparison with healthy peer. Fifteen patient with muscle disease whose mean age of 30.47±10.37 years and 15 healthy individuals whose mean age of 29.60±7.46 years were included. After the demographic informations of the individuals were recorded; muscle activation (superficial electromyography), range of motion and sit to stand duration (kinematic measurements) were assessed during standing. In terms of other factors that may affect standing, the individual's foot-ankle characteristics (Navicular Drop Test, subtalar angle measurement, foot length measurement, metatarsal width measurement, Foot Posture Index), muscle strength (hand-held dynamometer), muscle shortness (muscle shortness test), balance (Time Up Go Test), lower extremity functional strength (Five Repetition Sit to Stand Test), motor functions (Motor Function Measure Scale) and trunk control (Trunk Impairment Scale) were evaluated. As a result of the study, it was found that patients with muscle disease had higher muscle activation levels and longer periods compared to healthy individuals while standing from different height and floor characteristics, also they had more trunk flexion while standing from soft seat (p<0.05). Sit to stand activity of patient with muscle disease is related to muscle activation, range of motion, sit to stand duration muscle strength and shortness, balance, lower extremity functional strength and motor function (p<0.05). As a result many factors have been shown to play a role in standing of patients with muscle disease such as muscle activation and strength, seat height and hardness. The results of our study have shown that sit to stand actvity of patients with muscle disease was adversely affected and patients develop different motor strategies related to muscular, biomechanical, and environmental factors in order to standing.
