“…Different studies have shown that exercise helps the CTS symptoms subside. Exercise may help hand tendons in the wrist move more easily, preventing swelling or inflammation of tendons in the carpal tunnel (26, 27). In our study, probable CTS was more prevalent in assembly workers than in computer operators.…”

BackgroundCarpal tunnel syndrome (CTS) is common in the industrial setting. However,there is a controversy about the sole role of occupational ergonomic hazards in CTS.ObjectivesThis study was conducted among assembling workers of a detergent factory and computer users with the aims of A) determination of CTS prevalence and B) evaluation of personal risk factors and level of exposure to occupational risk factors via Quick Exposure Check (QEC).Materials and MethodsIn this descriptive cross-sectional study, 906 cases (332 assembling workers and 574 computer workers) were enrolled. CTS was assessed by symptoms on the Katz hand diagram and physical examination. QEC technique was applied to evaluate physical exposure to the risk factors.ResultsAccording to this study, the prevalence of probable CTS was 14% in men and 8.9% in women; the rate of probable CTS was significantly higher in assembly workers than in computer users (P < 0.001). Mean age and work duration in the probable CTS group was statistically higher than in non-CTS group. But both groups were in the same range (fewer than 30, P = 0.024, 0.004); BMI in the probable CTS group was slightly lower than in non CTS group, but BMI in both groups were in the normal range. Wrist ratio > 0.7 correlated with increased risk of probable CTS (P < 0.001) Prevalence of probable CTS was significantly higher in third and fourth levels of QEC (P < 0.001).ConclusionsAlthough this article had limitations, our findings suggest that the level of occupational exposure is an indicator of CTS development.

“…Surgery is considered the most definitive treatment, with as high as 70–90% of subjects reporting freedom from nocturnal pain after surgery [Katz et al,1998]. Nevertheless, surgery drives up costs and there have been long‐term follow‐up studies suggesting that patients who have undergone carpal tunnel release do no better that those who have been managed with conservative care [Nathan et al,2001]. Conservative treatments vary from injection of corticosteroids to neutral wrist splinting [Wilson and Sevier,2003].…”

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy of the median nerve characterized by paresthesias and pain in the first through fourth digits. We hypothesize that aberrant afferent input from CTS will lead to maladaptive cortical plasticity, which may be corrected by appropriate therapy. Functional MRI (fMRI) scanning and clinical testing was performed on CTS patients at baseline and after 5 weeks of acupuncture treatment. As a control, healthy adults were also tested 5 weeks apart. During fMRI, sensory stimulation was performed for median nerve innervated digit 2 (D2) and digit 3 (D3), and ulnar nerve innervated digit 5 (D5). Surface-based and region of interest (ROI)-based analyses demonstrated that while the extent of fMRI activity in contralateral Brodmann Area 1 (BA 1) and BA 4 was increased in CTS compared to healthy adults, after acupuncture there was a significant decrease in contralateral BA 1 (P < 0.005) and BA 4 (P < 0.05) activity during D3 sensory stimulation. Healthy adults demonstrated no significant test-retest differences for any digit tested. While D3/D2 separation was contracted or blurred in CTS patients compared to healthy adults, the D2 SI representation shifted laterally after acupuncture treatment, leading to increased D3/D2 separation. Increasing D3/D2 separation correlated with decreasing paresthesias in CTS patients (P < 0.05). As CTS-induced paresthesias constitute diffuse, synchronized, multidigit symptomatology, our results for maladaptive change and correction are consistent with Hebbian plasticity mechanisms. Acupuncture, a somatosensory conditioning stimulus, shows promise in inducing beneficial cortical plasticity manifested by more focused digital representations.

“…Nathan et al, 2001 studied the effects of long term aerobic exercise on median nerve conduction and symptoms associated with carpal tunnel. They postulated that long term aerobic exercise program improved circulation and oxygen delivery which helps in reducing nerve ischemia (the leading cause of carpal tunnel syndrome) thus improving median nerve conduction velocity 25,28 .…”
