Association of Scapular Dyskinesis with Neck and Shoulder Function and Training Period in Brazilian Ju-Jitsu Athletes

Does scapular dyskinesia affect upper extremity performance, proprioception, and body image in kickboxers? Case-control study

BACKGROUND

Scapular Dyskinesia (SD) is detected more frequently in athletes who do overhead activity sports. SD is more common in kickboxers who actively use their upper extremities. This study was conducted to compare upper extremity stabilization, proprioception and body image in kickboxers with and without SD.

METHODS

Kickboxing athletes participating in the study were divided into two groups according to whether they had SD or not. Presence of SD with Lateral Scapular Slide Test; Shoulder proprioception sense with digital inclinometer (Dualer IQ Pro, JTECH Medical Industries) at 40, 70, 90 and 135 degrees; Shoulder joint stabilization was evaluated with the Closed Kinetic Chain Upper Extremity Stabilization Test, and body image was evaluated with the Body Assessment Scale.

RESULTS

A total of 56 male kickboxing athletes with (n:27) and without (n:29) SD between the ages of 18-35 were included in the study. There was no difference between the groups regarding age, height, weight, body mass index, and 40° with 135° shoulder abduction proprioception sense (p > 0.05). There were differences between the groups in terms of sports history, 70° and 90° shoulder abduction proprioception sense, shoulder stabilization and body image (p: 0.001; p: 0.003; p: 0.003; p: 0.012, respectively).

CONCLUSION

Shoulder proprioception, shoulder joint stabilization, and body image in kickboxers with SD were better than kickboxers without SD. In addition, Kickboxers with SD performed in this sport for a longer time than kickboxers without SD.

Neck and Shoulder Pain with Scapular Dyskinesis in Computer Office Workers

Background and Objectives: Computer office workers spend long periods in front of a computer, and neck and shoulder pain are common. Scapular dyskinesis (SD) is associated with neck and shoulder pain. However, SD in computer office workers has not been elucidated. We aimed to investigate the prevalence of SD, neck and shoulder pain, disability, and working hours in computer office workers. Materials and Methods: In total, 109 computer office workers participated in this study. The results of a scapular dyskinesis test (SDT), lateral scapular slide test (LSST), neck disability index (NDI), shoulder pain and disability index (SPADI), visual analog scale (VAS) scores of the neck and shoulder, and working hours were recorded. Results: Ninety-eight computer office workers (89.9%) had SD. Computer office workers with SD had significantly higher NDI (p = 0.019), neck VAS (p = 0.041), and dominant shoulder VAS scores (p = 0.043). The LSST results showed a significantly greater distance (p = 0.016) in participants with SD. Conclusions: The prevalence of SD was very high in computer office workers, and neck and shoulder pain were more prevalent in workers with obvious SD.
