“…11, 24 Univariate analyses of this cohort showed that future CTS was predicted by exposure to higher hand/wrist exposures at work, consistent with recent studies. 25, 26 Unlike previous studies, workers with prolonged median nerve motor latencies were not at higher risk of future CTS in this cohort. Consistent with past studies, post-offer pre-placement screening was not an effective strategy for identifying future cases of CTS based on nerve conduction screening studies in this sample of newly hired workers; in fact, the rate of future CTS cases was slightly lower among the workers with abnormal POPP screen results than among those with normal studies.…”

Objective We determined the predictive validity of a post-offer pre-placement (POPP) screen using nerve conduction velocity studies (NCV) to identify future cases of carpal tunnel syndrome (CTS). Methods A cohort of 1648 newly hired manufacturing production workers underwent baseline NCS, and were followed for 5 years. Results There was no association between abnormal POPP NCV results and incident CTS. Varying NCV diagnostic cut-offs did not improve predictive validity. Workers in jobs with high hand/wrist exposure showed greater risk of CTS than those in low exposed jobs (Relative Risk 2.82; 95% CI 1.52, 5.22). Conclusions POPP screening seems ineffective as a preventive strategy for CTS.

“…In many studies, CTS has been more commonly reported in women. [15][16][17] Carpal tunnel syndrome initially affects the dominant hand and, then, involves the contralateral hand. Bilateral involvement was reported in 46.1 to 62% of the cases.…”

Objectives:We aimed to evaluate the sensitivity of second lumbrical-interosseous (L-I) technique and to compare the results with other electrophysiological methods in patients with carpal tunnel syndrome (CTS). Patients and methods:This cross-sectional study was conducted in an electrophysiology laboratory of a university hospital between January 2003 and January 2004. A total of 102 patients with CTS (174 hands) and 40 healthy controls (80 hands) were included. Median motor nerve conduction studies were obtained with recordings from the abductor pollicis brevis (APB), median sensory nerve conduction studies from digits I-III and at palm-wrist segment (P-W), median-ulnar sensory comparison at digit IV (M-U), and median-radial sensory comparison at digit I (M-R) were along with L-I technique. Results:The highest sensitivities were found in the median sensory conduction velocity across the palm-wrist (88%), and digit I-wrist segments (80%), median motor distal latency over the APB (77%), and L-I study (76%). The specificities of conventional tests were higher than the sensitivity of L-I method (63%).Conclusion: L-I method has a good diagnostic sensitivity in CTS; however, P-W, median sensory nerve conduction velocity at digit I and median distal motor latency are more sensitive than L-I method. Therefore, L-I method can be applied as a supportive technique in the evaluation of patients with CTS.

“…Although age, female gender, body mass index (BMI), diabetes mellitus, rheumatoid arthritis, hyperthyroidism, and previous wrist surgery, have been repetitively recognized as main risk factors for the CTS [6,10,11], sound evidence associates such disorder with workplace factors such as repetitive/prolonged hand-intensive activities, forceful exertions, awkward and/or static postures, vibrations, temperature extremes, and localized mechanical stress CTS [3,7,8,[12][13][14][15][16].…”

Background: Carpal tunnel syndrome (CTS) is a musculoskeletal condition that often impairs the fitness to work. Our aim is to retrospectively evaluate the association between physical exposures in meat processing industry in Northern Italy and the CTS, taking into account non-occupational factors. Material and Methods: A cross-sectional study was performed to include 434 workers (236 males, 198 females, 37.0±10.6 years old, working age: 12.6±10.8 years) from meat processing industries. Signs and symptoms were collected at the compulsory occupational medical surveillance. Occupational risk factors were assessed through a questionnaire and direct assessment by investigators. Adjusted odds ratios (ORadj) for factors of interest were estimated through binary logistic regression. Results: Diagnosis of the CTS was reported for 61 out of 434 subjects (14.1%) for an incidence of 11.3/1000 person-years. In general, signs and symptoms for the CTS were associated with the following demographic factors: smoking history (OR = 1.909, 95% confidence interval (CI): 1.107-3.293), previous traumas of the upper limb (OR = 3.533, 95% CI: 1.743-7.165), hypothyroidism status (OR = 7.897, 95% CI: 2.917-21.38) and, in the case of female participants only, previous pregnancies (OR = 2.807, 95% CI: 1.200-6.566) as well as a personal history of oral contraceptive therapy and/or steroidal replacement therapy (OR = 11.57, 95% CI: 4.689-28.56). The carpal tunnel syndrome cases were associated with the following occupational factors (> 4 h/day): forceful hand exertion (ORadj = 3.548, 95% CI: 1.379-9.131), repeated trauma of the hand (ORadj = 3.602, 95% CI: 1.248-10.395), repeated movements of the wrist (ORadj = 2.561, 95% CI: 1.100-5.960). Conclusions: Increasing levels of hand activity and force were associated with the increased CTS prevalence among participants. Recommendations have to be provided in order to reduce occupational exposure to these risk factors and improve medical surveillance. Med Pr 2017;68(2) :199-209
