Prevalence of work-related musculoskeletal symptoms among young orthopedics during the surgical practice: an intervention study.

BACKGROUND: Work-related muscle-skeletal symptoms (WRMS) represent a substantial social and economic impact on the way of work and have a high incidence in surgeons. In the literature, several studies address the impact of WRMS in surgeons performing gynecological, laparoscopic, and robotic surgery, but there are no studies in the field of orthopedic surgery. This pilot study aims to assess the effectiveness of a preventive program to reduce pain. METHODS: All workers filled in a standardized questionnaire, and postoperative pain in the operating room was quantified using a numeric scale (NAS). The intervention group followed ergonomic principles in the operating room supervised by a physiotherapist and specific physical exercises before and after surgery. Data were analyzed using the statistical program STATA rel. 14.0. RESULTS: Twenty-one surgeons were assigned to intervention groups and thirty-three to controls. At baseline, the two groups were homogeneous for anthropometric factors, and controls were older and with higher work seniority. Pain perception resulted in high in both groups in many body districts. At follow-up, after three months, the intervention group significantly reduced pain perception in all body districts for the lumbar back, knees, ankles and feet (p<0.05). In the control group, pain perception increased in all body districts investigated. CONCLUSIONS: We found a high prevalence of WRMS in young orthopedic surgeons, and we demonstrated the effectiveness of a preventive program through targeted ergonomic education and exercises for the most affected body districts.

Tailored physiotherapeutic intervention study for musculoskeletal disorders among video display terminal users.

BACKGROUND: Musculoskeletal disorders represent one of the most common complains among video display terminal (VDT) users and are responsible for an important burden of disease in white collars. METHODS: From May 2017 to March 2018, 69 VDT users working at Trieste hospitals were recruited for a training session aimed to reduce musculoskeletal disorders in white collars workers. Thirty-three were assigned to the intervention group, whereas 36 comprised the control group. The intervention group received three personalized 1-hour-one-to-one sessions with a physiotherapist and a thorough evaluation of their workstation. Data were collected at baseline (T0), at 2 months (T1) and at 6 months (T2) using a standardized questionnaire and analyzed with the software STATA. RESULTS: Overall pain significantly decreased in cases at T1 and T2 (p < 0.05). Headache significantly decreased in cases at T1 (p < 0.05). Body awareness significantly increased in cases both at T1 and T2 (p < 0.05). Headache was positively correlated with an increased perception of pain (Coef 6.85, CI95% 3.2-10.5; p < 0.001), while the intervention determined a significant reduction of overall pain during the follow up (OR 0.97, IC 0.95-0.99, p = 0.013). Cases showed a significant increase of the cranial-vertebral angle at the 6 months follow up (p < 0.05). CONCLUSION: A tailored physiotherapeutic intervention has showed a statistically significant decrease in osteoarticular pain and an increased body awareness in VDT users undergoing a personalized training session.v.
