简要总结
PURPOSE:
To perform a cross-cultural adaption of the KJOC Shoulder and Elbow score into the Arabic language, then to test its validity and reliability.
BACKGROUND:
Shoulder and elbow injuries are highly prevalent among overhead and throwing athletes, particularly in sports such as baseball, handball, volleyball, and tennis throwing. Accurate assessment of upper extremity function in this athletic population is essential for injury prevention, clinical decision-making, and monitoring return-to-sport outcomes.
The Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow Score is a sport-specific, patient-reported outcome measure (PROM) developed to evaluate functional performance, pain, and sport-related limitations in overhead athletes. It has been widely used and validated in several languages including Spanish, Germany, Japanese, and Greek; however, no validated Arabic version is currently available.
Simple literal translation is insufficient for patient-reported outcome measures. Instead, a structured process of translation, cultural adaptation, and comprehensive psychometric validation is required to ensure linguistic accuracy, conceptual equivalence, cultural relevance, and measurement reliability for Arabic-speaking athletes.
HYPOTHESES:
The study hypothesizes that the Arabic version of the KJOC shoulder and elbow score will demonstrate strong validity and reliability as an assessment tool for evaluating upper extremity function in symptomatic Arabic-speaking overhead athletes.
RESEARCH QUESTION:
Is the adapted Arabic version of the KJOC Shoulder and Elbow score valid and reliable for assessing upper extremity function in Egyptian symptomatic overhead athletes?
详细描述
This study will use a Descriptive, Methodological Design (Cross-Cultural Adaptation).
Description of Research Methodology: The study will follow standard international guidelines for cross-cultural adaptation (e.g., Beaton et al.).
PHASE 1: CROSS-CULTURAL ADAPTATION
The process includes five stages:
1) translation, 2) synthesis of translations, 3) back-translation to the original language, 4) committee analysis, and 5) pre-testing.

The KJOC Shoulder and Elbow score
时间窗: 4 weeks
The KJOC Shoulder and Elbow score is used to evaluate the functional status of athletes with shoulder and elbow disorders (Appendix II) (Silva et al., 2024). The KJOC is a 10-item visual analogue scale questionnaire given to patients; lower scores indicate a lower function or performance level, while higher scores indicate a greater function or performance level. The total score, which ranges from 0 to 100 points, is determined by adding together each individual item (Alberta et al., 2010). The KJOC score is the most sensitive for distinguishing minor differences in a throwing athlete's performance (Domb et al., 2010). KJOC is valid (Spearman: KJOC and DASH sports module =- 0.8036, KJOC and DASH =-0.6933) and reliable (Cronbach alpha of 0.9, indicating a high level of inter-item reliability (Domb et al., 2010), ICC= 0.802 (Erickson et al., 2018)).
Arabic version of DASH
时间窗: 4 weeks
The DASH is a 30-item self-report survey with 5-point Likert scales. The range of scores is 0 (no disability) to 100 (the most severe disability). It is a general non-specific PROM helpful for individuals with any upper limb musculoskeletal condition (Hudak et al., 1996). Items include 21 questions evaluating particular physical tasks (e.g., using a knife or turning a key), 5 items evaluating symptoms (e.g., pain, tingling), and 4 questions evaluating social functions (e.g., sleep and confidence) (David et al., 2022). DASH has been transculturally adapted to Arabic language (Alotaibi, 2010). The DASH-Arabic is a valid, responsive, and dependable upper extremity outcome measure (Alotaibi et al., 2016), (Appendix IV).
