Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Electromyographic activity: Electrical activity of the shoulder muscles is measured using surface electromyography (sEMG) with a Noraxon Wireless EMG device and includes the muscles of the shoulder area. Signals are recorded using bipolar surface electrodes according to the SENIAM protocol. Timepoint: Outcome variables are measured at two time points: before the exercise protocol (pretest) and after the exercise protocol (posttest). Method of measurement: Electromyographic activity: In this study, electrical activity of shoulder muscles will be measured by surface electromyography (sEMG) with the Noraxon Wireless EMG device. Muscle signals will be recorded at 90 degrees of abduction in the frontal, sagital, and scapular planes of motion. The muscles studied include the anterior deltoid, middle deltoid, posterior deltoid, supraspinatus, and infraspinatus. Signals will be recorded with bipolar surface electrodes according to the SENIAM protocol and with a distance of 2 cm between the electrodes. | — |
Secondary
| Measure | Time frame |
|---|---|
| Pain: Shoulder pain is measured using a visual analog scale (VAS) questionnaire. Timepoint: Outcome variables are measured at two time points: before the exercise protocol (pretest) and after the exercise protocol (posttest). Method of measurement: Pain: Pain in this study will be assessed using a visual analog scale (VAS).;Range of motion: Active range of motion of the shoulder joint in flexion, abduction, internal rotation, and external rotation will be measured using an EA8161 goniometer manufactured by MSD. Timepoint: Outcome variables are measured at two time points: before the exercise protocol (pretest) and after the exercise protocol (posttest). Method of measurement: Range of motion: In this study, the active range of motion of the shoulder joint in the directions of flexion, abduction, internal rotation, and external rotation will be measured using a goniometer model EA8161 manufactured by MSD. The measurements will be repeated twice by placing the goniometer in standard anatomical positions and their average will be used for analysis. The range of motion will be recorded up to the maximum pain-free point. | — |
