Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-26.
Sponsored by Elif Turgut · Observational
The Functional Arm Scale for Throwers (FAST) is a patient-reported outcome measure that assesses upper extremity function in overhead throwing athletes. This methodological study aims to cross-culturally adapt the FAST into Turkish (FAST-TR) and to evaluate its validity and reliability. The adaptation process follows Beaton's guidelines, including forward translation, synthesis, back translation, expert committee review, and pretesting in 30 athletes. Overhead athletes aged 18 years or older who have regularly participated in at least one overhead sport for at least 3 years complete a demographic and sports information form, the FAST-TR, the Turkish versions of the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score, and the Quick-DASH. A subgroup of participants completes the FAST-TR again 5 to 7 days later to assess test-retest reliability. Floor and ceiling effects, internal consistency, test-retest reliability, measurement error, construct validity, and known-groups validity between asymptomatic and symptomatic athletes are analyzed.
117 studies on the registry are indexed under Shoulder Injuries; 31 are open to participants now.
This study's planned enrollment of 217 is above the median of 60 across 46 observational studies indexed under Shoulder Injuries.

Overhead athletes with shoulder problem who continue participating in their sport.
Functional Arm Scale for Throwers - Turkish Version (FAST-TR) Score
The FAST is a patient-reported outcome measure consisting of 22 items and a 9-item pitcher/thrower module that assesses upper extremity function in throwing athletes. Total and subscale scores range from 0 to 100, with higher scores indicating greater disability. Internal consistency, test-retest reliability, and validity of the Turkish version will be evaluated.
Time frame: Baseline and 5-7 days after baseline
Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score
The KJOC is a 10-item questionnaire assessing shoulder and elbow function in overhead athletes using visual analog scales. Total score ranges from 0 to 100, with higher scores indicating better function. It will be used to evaluate the construct validity of the FAST-TR.
Time frame: Baseline
Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) Score
The Quick-DASH is an 11-item questionnaire with an optional 4-item sports/performing arts module assessing upper extremity disability. Scores range from 0 to 100, with higher scores indicating greater disability. It will be used to evaluate the construct validity of the FAST-TR.
Time frame: Baseline
Plan to share: No — Individual participant data will not be shared because the informed consent obtained from participants and the ethics committee approval do not cover public sharing of raw data.
