27 patients with elbow and wrist disorders were randomized to undergo traditional arm rehabilitation with or without core stabilization exercises. The purpose of this study was to determine whether a core stabilization program is effective in preventing compensatory movement patterns and improving physical function. Results indicated that stabilization training yielded significantly greater improvements in head, trunk and total compensation, as well as trunk strength. There were no significant differences between groups, however, in shoulder, elbow or wrist compensation, pain, joint limitation, endurance, fatigue, or disability scores.
