COMPARISON OF FACTORS RELATED TO THE KINETIC CHAIN BETWEEN ASYMPTOMATIC INDIVIDUALS AND THOSE WITH SHOULDER PAIN: ANALYSIS OF LUMBOPELVIC STABILITY, RANGE OF MOTION AND ISOMETRIC MUSCLE STRENGTH
Musculoskeletal system. Physical functional performance. Torso. Upper extremity.
Introduction: alterations in components of the kinetic chain may be present in different populations with shoulder pain. However, few studies have investigated whether the lumbopelvic complex stability, joint mobility, and muscle strength of the hip and trunk are altered in young and middle-aged adults when compared to asymptomatic individuals. Objective: to compare lumbopelvic stability, range of motion and isometric muscle strength of the hip, trunk, and shoulder complex between asymptomatic individuals and those with shoulder pain. Methods: this cross-sectional study will be carried out at the Universidade Federal do Rio Grande do Norte - Faculdade de Ciências da Saúde do Trairi. The sample will consist of 50 asymptomatic individuals matched by sex, age, and body mass index to 50 individuals with shoulder pain. The following outcomes will be evaluated: lumbopelvic stability (single-leg bridge test), range of motion (inclinometry), and isometric muscle strength (hand-held dynamometry) of the hip, trunk and shoulder complex. Statistical analysis will be conducted using IBM® SPSS® for Windows® 10 and the significance level will be set at 5%.
