| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cohort 1 (Mild) | Participants with mild self-reported thoracic outlet syndrome symptoms (visual analog scale score 1-3). |
| |
| Cohort 2 (Moderate) | Participants with moderate self-reported thoracic outlet syndrome symptoms (visual analog scale score 4-6). No intervention will be provided. |
| |
| Cohort 3 (Severe) | participants with severe self-reported thoracic outlet syndrome symptoms (visual analog scale score 7-9). No intervention will be provided |

| No intervention | Other | This is an observational cross-sectional study. No intervention will be provided. Participants will be assessed and stratified into four cohorts based on self-reported symptom severity of thoracic outlet syndrome using a visual analog scale (VAS) to investigate the relationship between symptom severity and upper extremity function/neural integrity. |
| Measure | Description | Time Frame |
|---|---|---|
| Range of Motion (ROM) of the Shoulder joint | Active and passive ROM will be measured using a standard goniometer. | Baseline |
| Range of Motion (ROM) of the Elbow joint | Active and passive ROM will be measured using a standard goniometer. | Baseline |
| Range of Motion (ROM) of the Wrist joint | Active and passive ROM will be measured using a standard goniometer. | Baseline |
| Isometric Muscle Strength of shoulder | Maximum voluntary isometric strength of shoulder muscles will be measured using a handheld dynamometer. | Baseline |
| Isometric Muscle Strength of elbow | Maximum voluntary isometric strength of elbow muscles will be measured using a handheld dynamometer. | Baseline |
| Isometric Muscle Strength of wrist | Maximum voluntary isometric strength of wrist muscles will be measured using a handheld dynamometer. | Baseline |
| Self-reported upper extremity function | The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, developed by the Institute for Work and Health, is used to measure patient-reported functional outcomes. The DASH questionnaire consists of 30 questions regarding limitations to complete physical activities due to upper extremity pain/impairment. Participants will be asked to respond to each question based on their experiences over the preceding week according to a 5-point Likert scale ranging from 1 (no difficulty) to 5 (unable to do). Responses will be scored out of 5 and averaged to produce a score out of 100 with higher scores representing greater disability. |

A total of 100 individuals (n=25 per cohort), aged 18-65 years, diagnosed with thoracic outlet syndrome will be recruited for this study. Participants will be recruited from local physical therapy clinics and physician offices. Participants will be screened for eligibility prior to being enrolled in the study and stratified into one of four cohorts based on the severity of self-reported symptoms using a visual analog scale: mild (scores 1-3), moderate (scores 4-6), severe (scores 7-9) and very severe (score 10). Exclusion criteria include a history of upper extremity surgery or other upper extremity disorders not related to thoracic outlet syndrome. All participants will provide written informed consent prior to participating in the study assessments.
