Purpose. To investigate the effect of cervical stability exercises (CSE) on neck pain and neck functional disability in patients with cervical spondylosis.
Methods. Randomized controlled trial. Overall, 40 patients of both genders with age ranged from 40-65 years with mild to moderate cervical spondylosis were recruited randomly and divided into two equal groups; Group (A) (control group), received traditional treatment of cervical spondylosis for 4 weeks, Group (B) (experimental group), received the same traditional treatment plus CSE for 4 weeks. Pre- and post-treatment assessment using Visual analogue scale (VAS) and neck disability index (NDI) were done for all patients.
Results. The comparison between both groups post-treatment revealed statistically significant reductions in VAS, as well as NDI total score and NDI subscores (p < 0.05) in favour of experimental group (B).
Conclusion. Cervical stability exercises have a significant effect on reducing pain and improving function in patients with cervical spondylosis.
Background: Mobile hand-held devices usage are on the rise in everybody's life that can be associated with physical health related problems, such as pain and numbness in the elbow and wrist and exposes forearm and hand to intense stresses at certain positions that may lead to peripheral nerve disorders. Purpose: To study correlation between forearm positions across elbow joint and ulnar nerve conduction velocity among mobile-hand held devices users. Design of the study: One shot case study. Subjects: Fifty healthy subjects from both genders, their age ranged from 20 to 40 years old. All subjects had body mass index between 18.5 and 24.9 Kg/m2. Method: Electromyography was used for measuring ulnar nerve conduction velocity across elbow joint at different angles (0 o extension, 45 o , 90 o and 120 o flexion) with different forearm positions (supination and pronation). Result: Multivariate Analysis of Variance revealed that there was a statistical significant difference in mean values of ulnar nerve conduction velocity at different angles of elbow flexion with forearm supination and pronation (P=0.001). There was a statistical significant difference in mean values of ulnar nerve conduction velocity between forearm pronation and supination at the different angles of elbow flexion (P=0.001). Conclusion: Usage of mobile hand held devices with forearm pronated and flexed elbow can decrease the motor conduction velocity of ulnar nerve more than other positions. As well as the best position for elbow joint during using mobile hand held devices is 0°-45° elbow flexion with elbow supinated.
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.
