Scapular dyskinesis among competitive swimmers.

To evaluate the prevalence of scapular dyskinesis (SD) in competitive swimmers during training sessions.

Methods:

Repeated measurement observational study. 20 young competitive swimmers were filmed before, at midpoint and at the end of a training session, performing shoulder flexion and abduction. scapular dyskinesis was examined separately by two assessors. Demographic and Quick Disabilities of the Arm, Shoulder, and Hand questionnaires were collected.

Results:

Scapular dyskinesis was observed in 30% of the swimmers before training, in 70%, an hour later, and in 80%, upon completion of the training session. The difference between the baseline and mid-practice was close to significance (p-value = 0.055), and between mid-practice and end of practice was significant (p = 0.004).

Conclusions:

This study confirmed that the prevalence of scapular dyskinesis increases throughout a training session in most swimmers. The main reason might be fatigue of the muscles which stabilize the scapula, therefore, when examining a sportsmen’s shoulder, it is important to examine the SD post-training or following simulation of the training session in the clinic.

Practical Implication: 

Scapular dyskinesis increases during a fatiguing practice. Therefore, coaches should focus on strengthening the scapular muscles, particularly with overhead motion to reduce shoulder injury in practice.
