Abstract(s)

Background: The demands of a sport such as surfing are high, paddling is one of the most common movements during a surfing session and therefore the load on the shoulder joint increases. Despite growing evidence regarding surf-related injuries, risk factors should be taking into consideration in a deeper analysis. This study was designed to contribute to greater knowledge of intrinsic factors that may be associated with shoulder injuries. Objective: The aim of this study is to determine if physical characteristics such as range of motion, shoulder strength, proprioception, scapular dyskinesia, core endurance and pectoralis minor length might be associated with shoulder injuries in surfers. Methods: Forty-one surfers aged between 18 and 45 years enrolled this study. Firstly, a socio-demographic questionnaire was filled out addressing anthropometric features and previous pain history (three months prior), the second part, an assessment was carried out: range of motion (ROM), shoulder muscle strength, proprioception (joint position sense), core endurance and pectoralis minor length was measured. Results: Shoulder active range of motion values did not differ between both groups. Normalized shoulder strength and IR:ER ratios for surfers with and without shoulder pain history was not significantly different. End-range position (80º) showed minor relative error scores on surfers who reported previous pain history. There is no correlation between dyskinesia and shoulder pain. Pectoralis minor length did not shown association with a painful shoulder. Symptomatic surfers did show differences in core endurance regarding prone bridge test. Conclusion: Shoulder pain is a recurring symptom both in competitive and free-surfers. All shoulder parameters: range of motion, strength, dyskinesia, pectoralis minor length, side bridge test, CKCUEST were independent of a history of pain story. End-range (80º) proprioception as well as prone bridge test shown significant differences between surfers who reported previous pain and surfers who did not have previous complains. This study provides a basis for more studies to carry on surf investigation.
