Abstract

Purpose: The aim of the study was to identify the differences in motor strategies of elderly people compared to young people during sit to stand activity. Material and methods: Fifty-five healthy individuals who were over 75 years of age (35 females and 20 males) participated voluntarily. Age, gender, body weight, body height, body mass index and dominant lower extremity of participants were recorded. Sit to stand test was performed by using the Balance Master System. Weight transfer time, center of gravity sway velocity, rising to stand index, and weight bearing symmetry were measured. Results: Elderly people generated significantly lesser rising to stand index than young people (p<0.001). Elderly people in our study preferred to bear weight on their right leg when compared to the left leg 98.41% to 1.59%, respectively. Conclusion: Elderly people chose different motor strategies compared with younger adults in terms of rising to stand index and weight bearing symmetry. Further study including muscular activation and kinematic assessments is needed to investigate how these different motor strategies occurred during sit to stand activity of elderly people. Better understanding of sit to stand activity in elderly will provide developing better assessment methods and therapeutic interventions to improve sit to stand activity of elderly people.
