This prospective observational study evaluates the effects of a structured cadaveric workshop on physicians' self-reported confidence in performing upper extremity ultrasound-guided procedures. The workshop consisted of theoretical instruction and supervised hands-on cadaveric practice focusing on shoulder, elbow, and wrist procedures. Confidence levels were assessed before and after the workshop using standardized questionnaires. The study also examined the influence of prior ultrasound experience, procedural volume, and academic seniority on baseline confidence and post-workshop improvement.

Ultrasound-guided musculoskeletal procedures are increasingly used in daily clinical practice because they improve procedural accuracy and reduce complication risk. However, upper extremity procedures require advanced sonoanatomical knowledge and technical proficiency due to the proximity of neurovascular structures and anatomical variability. Cadaveric workshops provide a realistic educational environment in which physicians can improve probe handling, needle guidance, and procedural confidence before performing these procedures in clinical settings.

This study evaluated the effectiveness of a one-day cadaveric musculoskeletal ultrasonography workshop focused on upper extremity ultrasound-guided procedures. The workshop included theoretical lectures and supervised hands-on cadaveric practice involving shoulder, elbow, and wrist procedures. Participants completed pre- and post-workshop questionnaires assessing self-reported confidence levels.

The primary objective was to determine changes in procedural confidence following workshop participation. Secondary objectives included evaluating the effects of prior ultrasound training, years of musculoskeletal ultrasonography experience, procedural volume, and academic seniority on baseline confidence and confidence improvement after the course.

Inclusion Criteria:

• Physicians participating in the cadaveric musculoskeletal ultrasonography workshop
• Willingness to complete pre- and post-workshop questionnaires
• Age ≥18 years

Exclusion Criteria:

• Failure to complete both pre- and post-workshop assessments
• Withdrawal from the workshop before completion

Physicians and physical medicine and rehabilitation trainees participating in cadaveric musculoskeletal ultrasonography workshops focused on upper extremity ultrasound-guided procedures.

De-identified participant-level questionnaire data, including demographic characteristics, professional background information, and pre- and post-workshop confidence assessments, will be shared.

Beginning 6 months after publication of the study results and continuing for 5 years following publication.

Access to de-identified participant-level data and supporting documents will be provided to qualified researchers who submit a methodologically sound research proposal. Data will be made available upon reasonable request to the corresponding author and may be used for educational or musculoskeletal ultrasonography research purposes.
