Neck Disability Index Detects Higher Neck-Related Disability Levels among Physiotherapists and Family Medicine Specialists than among Dentists

Abstract

Background: Healthcare workers who are in physical contact with patients are prone to work-related musculoskeletal disorders (WMSDs). Much is known about the prevalence of neck pain, but the extent of disability associated with neck pain among physical therapists (PTs), dentists, and family medicine specialists (FMs) is unknown. Methods: The prevalence of neck pain and Neck Disability Index (NDI) data were collected from 239 PTs, 103 FMs, 113 dentists, and 112 controls from June to August 2022. Results: The highest prevalence of neck pain was found in FMs (58.3%), followed by dentists (50.4%), PTs (48.5%) and controls (34.8%). The NDI% in PTs and FMs had higher values than controls: 14.6 ± 12.4, p = 0.02 for PTs, 14.9 ± 12.4, p = 0.01 for FMs vs. 10.1 ± 10.1 controls. The dentist group did not differ from controls (11.9 ± 10.2, p = 0.13). Mild, moderate, or severe forms of disability were more common in medical professionals than in controls (44.2%, 9.5%, and 1.5% vs. 37.5%, 7%, and 0%). Dentists were the youngest group with high functionality and the lowest degree of disability, comparable to the control population. Gender or age had no effect on NDI scores in this population. FMs, who represented the oldest group, showed age dependency (eleven years older in higher disability groups). Gender had no effect on NDI. In PTs, females predominated in all disability categories and PTs became five years older with increasing disability level. Conclusion: By using NDI in assessing neck-related WMSDs, we can detect medical professionals prone to more serious disability and potentially plan preventive actions.
