About this study
Sport climbing has recently become a highly popular sport and was included in the Summer Olympic Games 2021. Shoulder injury accounts for 15 to 20 percent of all sport climbing injuries, and it is the third most common problems, only surpassed by wrist and hand injuries. Sport climbing involves both open and closed chain movements of upper limbs. These prolonged and repetitive movements on vertical or overhanging terrain may lead to overuse and fatigue, which result in injuries. Sport climbing consists of multiple movement elements. Pull up with small holds is a basic movement in sport climbing, and activates many shoulder muscles, including trapezius, serratus anterior, latissimus dorsi. Studies related to sport climbing have focused on observing difference between sport climbers and non-sport climbers. Altered posture, increased scapulohumeral rhythm during arm elevation, and decreased shoulder angle during one-arm hanging have been observed in sport climbers. However, little studies have investigated whether climbers with shoulder injuries demonstrate different shoulder kinematics and muscle activation during tasks related to sport climbing. Therefore, the purpose of this study is to investigate the shoulder kinematics and muscle activation during pull-up with small holds in sport climbers with and without shoulder pain. Methods. Thirty sport climbers with shoulder pain and 30 healthy control subjects matched with gender, age, dominant hand and experience will be recruited in this study. All subjects will undertake physical examinations such as shoulder range of motion (ROM). Shoulder kinematics and muscle activation will be collected during arm elevation in the scapular plane and pull-up with gym-bar and 20mm depth small climbing holds. An electromagnetic tracking system will be used to measure bilateral scapular and humerothoracic kinematics. Surface electromyography (EMG) will be used to record muscle activation of bilateral upper trapezius, lower trapezius, serratus anterior and latissimus dorsi. Demographic data and physical examination will be analyzed by independent t test or Chi-square test. Two-way ANOVA will be used to test differences between groups in kinematics and EMG data at different phases of tasks. If significant interaction effect is found, Post-hoc pairwise comparison with Bonferroni correction will be used. The significant level is set at 0.05.

The record says: finished, as of the sponsor's last update on 9 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Shoulder kinematics during arm elevation (time frame: Immediately during the experiment). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2022.
