• Target: 121

Brief Summary

Objective: 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.

Outcome Measures

Primary Outcomes (1)

• Prevalence of Scapular Dyskinesis

  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.

  At baseline (single assessment session).

Secondary Outcomes (2)

• Shoulder Range of Motion (ROM)

  At baseline.

• Scapular Stabilizer Muscle Strength

  At baseline.

Study Arms (3)

o Group A:

27-31 years

o Group B:

Above 31-36 years

o Group C:

Above 36-40 years

Eligibility Criteria

• Age: 27 Years - 40 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)
• Sampling Method: Probability Sample

Study Population

This cross-sectional observational study will investigate the prevalence of scapular dyskinesis (SD) among licensed physical therapy practitioners in Egypt and will explore associated epidemiological factors. The study will be conducted between October 2024 and January 2025 after obtaining ethical approval from the Research Ethics Committee, Faculty of Physical Therapy, Cairo University (P.T.REC/012/005755). A total of 121 participants will be recruited based on a sample size calculation with 80% power at α = 0.05 (one-sample t-test). Eligible participants will be aged 27-40 years, actively working in clinical settings, with at least one year of clinical experience or exposure to physical activity, and free from current shoulder symptoms. Exclusion criteria will include recent acute shoulder/neck injury, history of upper body orthopedic surgery, neurological or musculoskeletal disorders affecting shoulder mechanics, high scapular-loading sports participation, and inability to complete

You may qualify if:

• Licensed physical therapy practitioners actively working in clinical settings (Soliño et al., 2024).
• 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.

You may not qualify if:

• Acute shoulder or neck injury within the last month (Jeong \& Kim, 2023).
• History of upper body orthopedic surgery (Jeong \& Kim, 2023).
• Known neurological or musculoskeletal disorders affecting shoulder mechanics (Burn et al., 2016).
• Participation in overhead or collision sports with high scapular loading (Burn et al., 2016).
• Inability to complete assessment procedures due to physical limitations (Soliño et al., 2024).
