Background and Objective: Patient scanning involves awkward movements of the body including twisting and rotation of the wrist, stretching of the arms and downward pressure in the use of the transducer depending on the size of the patient, resulting in strain on the wrist, shoulder and elbow joints. The aim of this study was to evaluate the prevalent of shoulder pains among Sonographers in Lagos State Nigeria. Materials and Methods: This was a cross sectional survey which involved Sonographers selected randomly based on our inclusion criteria. Data were obtained using self-administered questionnaire. An ethical approval was obtained from the study centers, and participant’s consent was properly sought. The obtained data were treated with high level of confidentiality. Data were processed and analyzed using both Excel version 2013 and Statistical Package for Social Sciences (SPSS) version 17. Statistical analyses were done using both descriptive and inferential (Chi-square) statistical tools with statistical significance set at p<0.05. Results: Out of 147 subjects studied, those that had shoulder pains were 64.3% (n=95). Out of 64.3% (n=95) of the subjects that experienced shoulder pains, those within age groups 26-30 years and 36-40 years were highest 14.30% (n=21) respectively. Chi-Square value (X²) = 33.028, degree of freedom =7, p=0.000 was noted when evaluating the relationship between age group and shoulder pains occurrence among the participants. This result revealed that Chi-Square value (X²) = 8.580, degree of freedom =3, p=0.035, which shows that there was statistically significant relationship between workload and shoulder pains. Conclusion: There was high prevalence of shoulder pains among sonographers in Lagos State as identified in this study. There was a statistically significant relationship between the age group and workload of participants and the occurrence of shoulder pains in this study.
