Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Intermuscular EMG Coherence During Submaximal Isometric Contractions | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | EMG-EMG coherence between muscle pairs (supraspinatus-infraspinatus, supraspinatus-middle deltoid, infraspinatus-middle deltoid) recorded with surface and fine-wire electromyography during 30-second sustained isometric shoulder scaption at 25%, 50%, and 75% of maximal voluntary contraction. Coherence is quantified in the delta (2-5 Hz), alpha (5-15 Hz), and beta (15-35 Hz) frequency bands. Coherence values range from 0 (no shared neural drive) to 1 (complete shared neural drive). |
| Primary | Intermuscular EMG Coherence During a Fatiguing Contraction | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | EMG-EMG coherence between muscle pairs (supraspinatus-infraspinatus, supraspinatus-middle deltoid, infraspinatus-middle deltoid) in the delta (2-5 Hz), alpha (5-15 Hz), and beta (15-35 Hz) frequency bands during a sustained isometric contraction at 25% of maximal voluntary contraction held until the endurance limit (force drop of 5% MVC). Values range from 0 (no shared neural drive) to 1 (complete shared neural drive). |
| Secondary | Acromiohumeral Distance | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Shortest linear distance between the inferior edge of the acromion and the humeral head, measured with ultrasound at rest (0° abduction) and during active shoulder abduction at 50% MVC at 45° and 60°. Each value is the average of 3 measurements. Measured in centimeters. |
| Secondary | Supraspinatus Tendon Occupation Ratio | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Ratio of supraspinatus tendon thickness to acromiohumeral distance, calculated as (tendon thickness / AHD) × 100, measured with ultrasound at 0°, 45°, and 60° of shoulder abduction. Each value is the average of 3 measurements. Expressed as a percentage. |
| Secondary | Shoulder Pain and Disability Index (SPADI) | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Self-administered questionnaire assessing shoulder pain and difficulty with upper-extremity activities of daily living. Total score ranges from 0 to 100, with higher scores indicating greater pain and disability. |
| Secondary | Muscle Fatigue Rate | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Slope of the EMG median frequency over time for the supraspinatus, infraspinatus, and middle deltoid during the sustained fatiguing contraction, calculated from surface and fine-wire EMG. A steeper negative slope indicates faster fatigue. |
| Secondary | Muscle Onset Time During Ramp Contractions | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Onset time of the supraspinatus, infraspinatus, and middle deltoid relative to force onset during isometric shoulder abduction ramp contractions (0 to 100% MVC at 7.5% MVC/s). Onset is defined as EMG amplitude exceeding 3 standard deviations of resting baseline for at least 25 ms. Measured in milliseconds. |
| Secondary | Motor Unit Recruitment Threshold | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Force level at which individual motor units in the supraspinatus and middle deltoid are recruited during ramp contractions, identified from fine-wire EMG as the first of four consecutive spikes. Expressed as percentage of maximal voluntary contraction (% MVC). |
| Secondary | Motor Unit Initial Firing Rate | Baseline, 2 weeks (mid-intervention), 4 weeks (end of intervention), and 8 weeks (4 weeks after the end of intervention) | Firing rate of individual supraspinatus and middle deltoid motor units at recruitment during ramp contractions, calculated as the average of the first three inter-spike intervals. Measured in hertz (Hz). |
