This study will aim to determine the prevalence of scapular dyskinesis (SD) among Egyptian physical therapy practitioners and will explore associated epidemiological factors, including age, sex, BMI, shoulder and neck symptoms, and scapular stabilizer muscle strength.
Design:
A cross-sectional observational study will be conducted, including 121 licensed Egyptian physical therapists aged 27 to 40 years. Participants will be divided into three age-based groups.
Methods:
Each participant will undergo a clinical examination for SD using the Scapular Dyskinesis Test (SDT) and the Lateral Scapular Slide Test (LSST). Pain intensity will be assessed using the Visual Analog Scale (VAS), and musculoskeletal symptoms will be recorded using the Nordic Musculoskeletal Questionnaire (NMQ). Shoulder range of motion and the strength of scapular stabilizer muscles (serratus anterior, middle, and lower trapezius) will also be evaluated. Statistical analysis will include Chi-square tests and one-way ANOVA at a significance level of p \< 0.05.

Age between 27 and 40 years (Jeong \& Kim, 2023).
Minimum of one year of clinical experience or exposure to physical activity (Jeong \& Kim, 2023).
No current shoulder pain or symptoms at the time of assessment (Soliño et al., 2024).
Willingness to participate and provide informed consent.
Exclusion Criteria:

History of upper body orthopedic surgery (Jeong \& Kim, 2023).
Known neurological or musculoskeletal disorders affecting shoulder mechanics (Burn et al., 2016).

Inability to complete assessment procedures due to physical limitations (Soliño et al., 2024).
Primary outcome measure(s)
Prevalence of Scapular Dyskinesis — At baseline (single assessment session). Determined by the proportion of participants diagnosed with abnormal scapular movement patterns using the Scapular Dyskinesis Test (SDT) and Lateral Scapular Slide Test (LSST).
Measurement Method:
SDT: Observation of scapular motion during repeated shoulder flexion and abduction with light weights. Abnormal motion recorded as "Yes," normal as "No."
LSST: Measurement of distance from scapular inferior angle to the nearest spinous process in different arm positions; \>1.5 cm side-to-side difference indicates dyskinesis.
