| Resumo: | Introduction: It is not clear in the literature whether individuals with unilateral shoulder pain present differences in shoulder complex muscle strength and endurance between symptomatic and asymptomatic limbs. The objective of the study is to compare the strength and resistance of the muscles involved in abduction in the scapular plane and external rotations of the shoulder between the limbs of individuals with unilateral pain, as well as the perception of pain and effort during the tests. Materials and methods: Fifteen individuals with unilateral shoulder pain underwent assessment of strength and static resistance of the muscles that perform abduction in the scapular plane and external rotations of the shoulder, and were asked about their perception of pain (0-10) and effort (1 -10) after carrying out the tests. For comparison between limbs, the paired Student's T test (normal distribution) and the Wilcoxon test (non-normal distribution) were used. Significance p<0.05 was adopted. Results: When comparing the strength of the muscles that perform shoulder abduction in the scapular plane, the limb presented lower strength (p<0.01), greater pain (p<0.01) and perceived effort (p=0.02) . For the strength of the muscles that perform external shoulder operations, there was no difference between the limbs, however there was a greater perception of pain (p<0.01) in the symptomatic limb. When comparing the resistance time, there was no difference between the limbs, but there was a greater perception of pain during the test of the tissues that perform shoulder abduction in the scapular plane (p<0.01) and the muscles that perform the external shoulder joints (p<0.01) no symptomatic members. There was also a greater perception of effort (p=0.02) in the symptomatic limb for the resistance of the tissues that carry out external rotations of the shoulder. Conclusion: Individuals with unilateral pain in the elevated shoulder have lower strength and greater perception of pain and effort in the symptomatic limb, in the shoulder abduction test in the scapular plane. Regarding resistance, individuals reported greater pain during the shoulder abduction test in the scapular plane and greater pain and effort during the shoulder external rotation test on the symptomatic side. |
