Core exercises elevate trunk stability to facilitate skilled motor behavior of the upper extremities

Abstract

The purpose of this study was to investigate the influence of core exercises on upper extremity function relative to skilled motor behavior and postural sway. We examined the effects of core exercises on the skilled motor behavior and postural sway of 40 healthy students who were assigned randomly to the core exercise group or the control group. Independent variable is extent of exposure to core exercise and dependent variables are skilled motor behavior and postural sway. A Purdue pegboard which measures skilled motor behavior and a stabilometer which measures postural sway were used to evaluate the influence of core exercises. Pre-intervention and post-intervention skilled motor behavior and postural sway were compared between the core exercise group and control group using the Wilcoxon rank sum test; a significance level of α = 0.05 was considered statistically significant. Also, we investigated the application of core exercises in a clinical setting for one patient with cerebral vascular disease. The post intervention skilled motor behavior (p = 0.04) and postural sway, LNG (p = 0.05), LNG/TIME (p = 0.04) and X LNG (p = 0.02) were significantly higher in the core exercise group than control group. In the case report, there were good results; function of the upper extremity improved after doing the exercises. There were positive changes in some daily living activities. Core exercises are likely to enhance trunk stabilization to improve upper extremity function. It is possible for core exercises to be adapted for patients.
