Objective: People with Anterior Cruciate Ligament (ACL) reconstruction need to have almost automatic postural control to focus on their athletic skills. Continuous cognitive task is a method for removing attention from postural control. The effects of continuous cognitive task on postural control of people with ACL reconstruction has been assessed by laboratory tools; however, its effect using ...

Introduction and Purpose: Due to the importance of functional balance tests assessment with emphasis on parameters influencing the balance including somatotype, this study undertaken to determine the reliability of functional balance tests (static, semi-dynamic and dynamic) in endomorphe healthy women within 24-34 years old. Methodology: 25 female endomorphe with the average and standard dev...

Objectives: The main goal of this study was to investigate the impact of difficulty level of postural task on dual task performance in young and older adults. Methods & Materials: 20 young (20-30 years) and 20 elderly (65-70 years) participants were selected by non-probable sampling method. Postural tasks (standing with parallel feet on the hard and foam surface) and cognitive task retrieved...

Background and Objective: Different morphologies are factors for the effectiveness of training programs on subjects. The aim of this study was the effect of 8-week Tai Chi exercise on static and dynamic balance in women with multiple sclerosis (MS) with emphasis on mesomorph and endomorph's morphology. Materials and Methods: In a clinical trial, 48 patients with MS were purposefully select...

The purpose of the present study was to investigate the effect of dual task training including balance sit-to-stand and cognitive exercises on postural control of sit to stand of elderly women with a history of falling. 15 elderly women were randomly divided into control (n=7) and experimental (n=8) groups. Participants implemented training protocol for four weeks in both experimental (balance ...
