“…Among earlier studies of the work-relatedness of CTS, many had small sample sizes, used varying definitions of CTS, and did not consistently account for known personal risk factors such as increasing age, high body mass index (BMI), and comorbid diseases such as diabetes mellitus.8, 9 Similarly, numerous recent studies characterizing the personal factors associated with CTS have not adequately measured or analyzed occupational factors.8, [10][11][12] Other recent studies have shown that both personal and occupational factors are independently associated with CTS. [13][14][15] Evaluating the independent contributions of occupational versus nonoccupational risk factors for CTS has implications for prevention, treatment, and for medical-legal issues.…”

., "Risk factors for carpal tunnel syndrome and median neuropathy in a working population". Journal of Occupational and Environmental Medicine, 50, 12, 1355-1364. 2008. Methods: A cross-sectional assessment of 1108 workers from 8 employers and 3 unions completed nerve conduction testing, physical exam, and questionnaires. CTS was defined by median neuropathy and associated symptoms.Results: Eighteen workers had CTS and 131 had evidence of median neuropathy. CTS was highest among construction workers (3.0%) compared to other subjects (<1%). Logistic regression models for median neuropathy both personal and work-related risk factors. Workrelated exposures were estimated by two methods: self-report and job-title based ratings.Conclusions: Both work and personal factors mediated median nerve impairment. Construction workers are at an increased risk of CTS so awareness should be raised and interventions shouldspecifically target this risk group.

“…It is possible that they were documenting edema of the carpal tunnel. Previous studies of hand and wrist dimensions have reported a higher wrist index (wrist depth/wrist width) in patients with CTS when compared with controls [21]. In one study by Farmer, the findings provided some support for an association between a high wrist index and CTS [22].…”

Objectives: To determine whether patients with carpal tunnel syndrome have an objective swelling of their hands.Design: A prospective, cross-sectional study of consecutive patients. Setting: Two independent electromyographic laboratories.Participants: Sixty-three patients referred for electrodiagnostic work-up.Interventions: NCS/EMG testing and volumetric analysis. Limb volume was measured using the water displacement method using a volumeter. Main Outcome Measures: Differences in volume (DHV) and EMG/NCS data.Results: EMG results indicated that 24 subjects (38%) had findings consistent with CTS. Data concerning subjective swelling was available for only six of these 24 subjects. The data, which are limited by low power, indicate that there was no difference 1) between the volume of the affected hand and the unaffected hand among those with CTS; 2) between the DHV of those with CTS and those without;. 3) Patients with lower extremity complaints had significantly less DHV than those with an upper extremity complaint (p< 0.0034, excluding patients with both upper and lower extremity complaints). Conclusions:Though a patients' perception of hand swelling has previously been determined to be an indicator of CTS severity, there was no correlation found in this study between CTS and objective measures of swelling. However patients with an upper extremity complaints had a statistically larger DHV than those with a lower extremity complaint (p<0.0034), suggesting that objective swelling might be present under some unknown circumstances. As this study was limited by a low power, further investigation is warranted in this area.

Introduction Carpal tunnel syndrome (CTS) is thought to be due to compression of the median nerve in the carpal tunnel. It is known that carpal tunnel pressures are elevated in wrist postures of flexion and extension and in those patients with CTS. Classic symptoms of CTS include night waking with pain, tingling, and numbness. These classic symptoms stimulated our interest in the relationship of sleep to the development of CTS. Method We reviewed the literature surrounding the epidemiology of CTS and the literature regarding sleep disturbances. Through careful distillation of these studies and a process of reasoning, we have developed a hypothesis for a causal mechanism of CTS.Results Epidemiologically, it has been shown that CTS is associated with age, gender, increased body mass index (BMI), diabetes, pregnancy, and is more common in some populations. The same associations noted above for CTS are strongly associated with sleep disturbances. Sleep disturbances due to age, gender, BMI, pregnancy, and population variations are all associated with sleeping in the lateral position supporting the hypothesis that a common causative mechanism of CTS is sleeping in a lateral position. Discussion We believe that the epidemiologic associations with CTS act through a common causative mechanism, increased sleeping in the lateral position which puts the wrist at increased risk of flexion or extension, compressing the median nerve in the carpal tunnel. This hypothesis is simple and explains the connection between a previously unconnected group of epidemiologic associations. This realization has real clinical significance in that it focuses our attention on the early disorder when it is completely reversible. It clarifies previously confused clinical circumstances, creates research questions that can be tested, and it invites us to change our clinical perspective in this most common form of nerve compression.
