Results indicated that the prevalence of neck pain in dentists appears to be high. Therefore, further studies on different preventive strategies in dentists' population seem necessary.
To clarify the significance of mechanical impairments, pain, and functional limitations as predictors of chronic low back pain (LBP). Ninety patients with chronic nonspecific low back pain (CNSLBP) were prospectively studied with clinical tests and questionnaires. Changes in muscle extensibility and endurance tests were evaluated and changes assessed in LBP intensity on numeric rating scale 0–10 and severity with Oswestry Disability Index (ODI) 0–100. In the present study we found significant associations between the 4 muscle extensibility and 2 endurance tests and pain at nonspecific patients with chronic LBP (P<0.005). The 2 muscle extensibility and 1 endurance tests were in complete equilibrium with ODI disability and hence showed similar results (P<0.005). The associations between the muscle extensibility and endurance tests and pain were significantly elevated in patients with nonspecific chronic LBP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
