It is important to improve the routine ADL(activities of daily living) in the elderly and then diverse and various therapeutic interventions or exercises are applied for the therapy. Generally, to increase the efficiency of the exercise and prevent the injury, the stretching is commonly used . Indeed, there are many case that the elderly complain of the difficulties to control the balance after the stretching [2, 3]. However, previous studies about the effects of stretching after or during the stretching have focused mainly on the histological or neurological changes and there are few studies that focused on the temporary balance control in the elderly [4, 5]. Thus, the purpose of this study was to investigate the perturbation recovery of five minutes of plantar-flexor static stretching (PSS) in the elderly.
Materials and methods
Thirty-one participants aged over 65 years performed 5 min-PSS in the form of wedge board standing. The sway length of each subject’s COM (center of mass) was measured to examine the subject’s static balance. It was measured for one minute in quiet standing with the eyes closed. Sway length was measured for 1 minute which was divided in three 20-second-sections before and after stretching.
Comparison of sway length standing before and after 5 minutes plantar-flexor static stretch.
