5 Clinical Trials for Various Conditions
To examine and compare the effect of a novel stretching technique and traditional stretching on glenohumeral range of motion, strength, maximum voluntary contraction, pain, and subject satisfaction in overhead athletes with glenohumeral internal rotation deficits through a randomized clinical study.
The goal of this research study is to compare the effects of pelvic alignment versus diaphragmatic breathing on range of motion in the shoulder joint in both athletic and nonathletic population. The investigators plan to have approximately 45 participants to take part in this study. Subjects will be assigned into three groups. Group 1 will perform both pelvic alignment and diaphragmatic breathing exercises. This group will be used as the standard or control group. Group 2 will perform pelvic alignment exercise only; and Group 3 will perform diaphragmatic exercises only. The shoulder internal rotation range will be assessed in all three groups. Maximal expiratory rate will be measured in group 3 to assure improved diaphragmatic breathing in subjects. The shoulder internal rotation range in group 2 \& 3 will be compared to the shoulder range of motion in the standard group.
Interventions including glenohumeral mobilization, sleeper stretches, and thoracic manipulation have been proposed for individuals with loss of shoulder range of motion (ROM). However, the effect of these interventions on shoulder ROM, joint translation, and muscular activity have not been studied in combination.
The primary purpose of this study is to determine if the loss of internal rotation following a throwing session is best restored through soft tissue stretching with the sleeper stretch or with scapular repositioning with the 90/90 hip lift with balloon blow exercise. This study will progress the body of research related to internal rotation deficits with regards to baseball throwers. The research will be relevant to clinicians who treat patients with baseball players with internal rotation loss. High school baseball players will be the targeted subjects for this study. They will perform two exercises (one per week) designed to increase shoulder internal rotation over the course of three weeks with one week of rest between intervention weeks. The primary outcome will be shoulder internal rotation range of motion improvements over the course of one week's time. There are no known adverse risks to either intervention.
The purpose of this study is to determine if stabilizing the scapula (shoulder blade) during a common shoulder stretch is more effective at improving shoulder range of motion than not stabilizing the scapula. Investigators hypothesize that scapular stabilization during horizontal adduction stretching will demonstrate greater gains in shoulder range of motion than stretching without scapular stabilization.
