The Impact

The costs of occupational injuries occurring due to the repetitive use of hand tools are large in terms of both dollars and pain and suffering. One of the most frequently used hand tools in industry is the vertical hanging screwdriver or nutdriver. Although the use of this tool has been related to wrist injuries such a carpal tunnel syndrome, there is very little known about the impact of tool design on such injuries. The paper presents a preliminary study that uses EMG to evaluate power screwdriver design parameters.

Background: Research has suggested that persistent sensory and motor impairments predominate the symptoms experienced by patients with carpal tunnel syndrome (CTS); with intermittent pain symptoms, being less predominant. Objective: The study aims to determine the relative contribution of sensory, motor and pain impairments as contributors to patient-report or performance-based hand function. Methods: Fifty participants with a diagnosis of CTS confirmed by a hand surgeon and electrodiagnosis were evaluated on a single occasion. Impairments were measured for sensibility, pain and motor performance. A staged regression analysis was performed. In the first step, variables with each of the 3 impairment categories were regressed on the Symptom Severity Scale (SSS) to identify the key variables from this domain. Models were created for both self report (Quick Disabilities of arm, shoulder and hand- Quick DASH) and performance based (Dexterity) functional outcomes. Backward regression modelling was performed for SSS and then, to allow comparability of the importance of different impairments across models, the 7 significant variables from the SSS model were forced into the models. Results: Variables: age, touch threshold and vibration threshold of the little finger of unaffected hand, median-ulnar vibration threshold ratio of affected hand, mean pain tolerance of unaffected hand, grip strength and pinch strength of affected hand, explained 31%, 36% and 63% of the variance in SSS, Quick DASH and dexterity scores, respectively. Conclusion: Hand function in patients with CTS is described by variables that reflect sensory status of the median and ulnar nerves, the persons pain threshold, grip and pinch strength impairments and age.

Tunnel Syndrome

BACKGROUND: Carpal tunnel syndrome (CTS) is a common disorder among occupations where upper extremities are actively involved in. Many occupational and non-occupational risk factors may contribute to this disorder. Knowledge regarding occupational risk factors can guide us to implement interventional programs. OBJECTIVE: The aim of the present study was to assess the prevalence and severity of CTS symptoms among butchers and their association with several occupational and non-occupational risk factors. METHODS: In this study, 152 butchers in Hamadan, Iran, were examined. The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was used to investigate the severity of CTS symptoms among the individuals. Several risk factors such as body mass index (BMI), wrist ratio, active working hours per day, working experience, and the ergonomic quality of hand tools used by butchers were also investigated. Statistical tests such as the crude and robust regression were used to analyze the data. RESULTS: The prevalence of moderate and mild symptoms of CTS were 7% and 54%, respectively. Moreover, 39% of the butchers were free of CTS symptoms. Crude regression analyses showed that the severity of CTS symptoms had a significant relationship with age, work experience, active working hours per day, working hours per week, and ergonomic quality of the hand tools (p value <0.05). There was no significant relationship between the severity of CTS symptoms and wrist ratio and BMI. Results of the robust regression analysis showed a significant relationship between the severity of CTS symptoms with experience, active working hours, and quality of the hand tools. CONCLUSION: Occupational risk factors such as working experience, active working hours per day, and the ergonomic quality of hand tools are significant risk factors of CTS symptoms among butchers. Slippery handle is the main non-ergonomic feature of knives and cleavers used by butchers. There was no association between BMI and wrist ratio with CTS symptoms.

Abstract Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy which can cause severe sleep disturbance. Carpal tunnel release (CTR) is a choice for severe cases, which has shown to improve sleep quality, but the available evidence is limited. This study aimed to investigate the impact of CTR on sleep quality and hand symptoms and functions in patients with CTS. Methods This was a prospective study in 2019–2020 on patients with CTS and poor sleep quality undergoing CTR. Patients were evaluated before and at 1, 3, and 12 months after CTR by the Pittsburgh sleep quality index (PSQI) and Boston carpal tunnel syndrome questionnaires. Results There were 33 patients with 27 females (82%) and a median age of 51 years. The median time of CTS diagnosis and having sleep disorder before CTR were 12 and 6 months, respectively. The outcomes significantly improved after CTR, with the median PSQI and Boston symptom and function scores reduced from 12, 33, and 23 before CTR to 9, 14, and 11 at 1 month; 7, 13, and 9 at 3 months; and 1, 11, and 8 at 12 months postoperatively, respectively. The correlations between the PSQI and Boston symptom and function scores were > 0.6 at all time-points. Conclusions Surgical decompression significantly improves sleep quality and the hand symptoms and functions in patients with CTS. Long-term evaluations are lacking and thus are required in future studies.
