Tunnel Syndrome

Carpal Tunnel Syndrome (CTS), a type of Repetitive Strain Injury (RSI) is the most commonly work related musculoskeletal disorder (WMSD) that can lead to temporary as well as permanent disabilities. The CTS is marked by pain and paresthesia. Present study has been conducted on the 60 workers comprising of 46 men (mean age of 34.43 ± 8.40 years, range 18-52 years) and 14 women (mean age of 34.78 ± 9.14 years, range 22-50 years) engaged in Ethylene Propylene Diene Monomer (E.P.D.M.) assembly unit. Symptoms present are nocturnal pain, numbness, tingling and low hand grip strength. The study has been done in actual industrial environment through health surveillance, Phalen’s and Tinel’s Tests, hand grip strength tester, and weighing machine. The aim of this study is to do analysis to check the susceptibility of CTS symptoms amongst men and women on the basis of repetitive and non repetitive work. The F-Test and ANOVA using orthogonal array have been applied for statistical data analysis in order to quantify and evaluate the importance of possible symptoms on CTS risk factor. Analysis shows that the women workers are more susceptible to CTS symptoms than their male counterparts. It also reveals that grip strength below 35 Kg and high tingling prevalence ratio are the most alarming symptoms for CTS occurrence among workers in E.P.D.M assembly unit.

This study highlights the benefits of carpal tunnel release (CTR) in four patients presenting with complex regional pain syndrome (CRPS) after hand surgery who also had carpal tunnel syndrome (CTS) diagnosed clinically and by nerve conduction studies. Three of the patients underwent pre- and postoperative volumetric, circumference, grip strength and range of motion measurements. The Disabilities of the Arm, Shoulder and Hand (DASH) functional outcome measure and pain scores were also used. There was almost complete resolution of CRPS symptoms in all four patients, with notable reductions in oedema and improvements in grip strength and range of motion. There were also improvements in DASH outcome scores and pain scores after CTR.

Wrist Splint

Background: Different types of splints have been used as a conservative intervention to improve symptoms in patients with Carpal tunnel syndrome (CTS). Although a number of studies have been undertaken to compare different splints, information and understanding of the influence of these interventions are lacking. Objectives: The purpose of this study was to compare the effect of a classic thermoplastic wrist splint or a wrist splint with an additional metacarpophalangeal unit on pain, function, grip strength, and pinch strength in patients with mild-to-moderate carpal tunnel syndrome. Study design: Quasi experimental design. Methods: A total of 24 patients received conservative treatment using either the classic wrist splint or the wrist splint with the metacarpophalangeal unit for a period of 6 weeks. Primary outcome measures were pain, function, grip strength, and pinch strength. Data were collected immediately before and after using the two types of splints at baseline (0 weeks) and 6 weeks. Statistical analysis was performed using the paired t-test and an independent t-test. Results: Compared to baseline, both the classic thermoplastic wrist splint and the wrist splint with a metacarpophalangeal unit significantly decreased pain and increased function, pinch strength, and grip strength. Comparisons of the two types of splints for grip strength ( P = 0.675) and pinch strength ( P = 0.650) revealed that there were no significant differences between the two after 6 weeks of wear. However, there were significant differences in pain levels ( P = 0.022) and the Disability of the Arm, Shoulder, and Hand score ( P = 0.027) between the two types of splints from baseline to 6 weeks. Conclusion: The wrist splint with a metacarpophalangeal unit was more effective than the classic thermoplastic wrist splint in pain reduction and improvement of function. Clinical relevance A wrist splint with a metacarpophalangeal unit may be an appropriate conservative treatment in the rehabilitation of patients with mild-to-moderate carpal tunnel syndrome.

Abstract Background:Nerve conduction study (NCS) is the only useful test for objective assessment of carpal tunnel syndrome (CTS). However, the relationship between pre- and postoperative NCS and clinical outcomes was unclear. This study aimed to determine whether pre- and postoperative (6 months) NCS could predict patient-oriented and motor outcomes (6 and 12 months postoperatively) in patients with CTS.Methods:Of the 85 patients with CTS, 107 hands were analyzed from March 2011 to March 2020. All patients underwent open carpal tunnel release and were examined using the disabilities of the arm, shoulder and hand (DASH) questionnaire and grip strength (GS) preoperatively and 6 and 12 months. Moreover, NCS was examined preoperatively and 6 months postoperatively. Distal motor latency (DML) and sensory conduction velocity (SCV) were the parameters used for NCS. The correlation coefficient between NCS and DASH or GS was calculated. A receiver operating characteristic curve was utilized to determine the NCS threshold value to predict DASH and GS improvement.Results:The average scores of GS preoperatively and 6 and 12 months postoperatively were 21.3, 22.3, and 22.8, respectively. On the other hand, the average scores of DASH preoperatively and 6 and 12 months postoperatively were 28.8, 18.3, and 12.2, respectively. The average NCS scores (DML and SCV) preoperatively/6 months postoperatively were 7.3/5.4 and 27.8/36.7, respectively. Preoperative NCS did not correlate with DASH and GS. Postoperative SCV correlated with the change in grip strength (6–12 months, r = 0.67; 0–12 months, r = 0.60) and DASH (0–12 months, r = 0.77). Moreover, postoperative DML correlated with the change in DASH (6–12 months, r = -0.33; 0–12 months, r = -0.59). The prediction for the improvement of GS/DASH achieved a sensitivity of 50.0%/66.7% and a specificity of 100%/100%, at an SCV cutoff score of 38.5/45.0 or above. The prediction for improvement of GS/DASH achieved a sensitivity of 83.3%/66.7% and a specificity of 100%/66.7% at a DML cutoff score of 4.4/4.4 or below.Conclusions:NCS at 6 months postoperatively can be used to predict the improvement of clinical outcome after 6 months postoperatively in patients with CTS.

Abstract Osteoarthritis is a common degenerative disease that most frequently involves the hand. The objective was to compare clinical functional outcome measures including hand grip, pinch strength, and dexterity with various electrophysiological measures in patients of different ages with hand osteoarthritis with or without the presence of carpal tunnel syndrome (CTS). Patients with hand osteoarthritis (208 patients, 404 hands) who underwent hand-function tests and motor and sensory nerve conduction studies (NCS) between June 2015 and June 2016 were enrolled. The patients’ hands were assigned to carpal tunnel syndrome (CTS) (206 hands; mean age, 56.37 ± 10.52; male:female, 46:160) or control groups (198 hands; mean age, 57.88 ± 9.68; male:female, 55:143). The strength of hand grip and lateral pinch, the time required to complete the nine-hole pegboard test (9HPT), and motor and sensory nerve conduction parameters were measured and compared across age groups and between hands with or without CTS. The CTS group showed significantly lower hand grip and lateral pinch strength, and a longer time to complete the 9HPT in comparison with the control group. Female patients showed significantly lower hand grip and lateral pinch strength than male patients. However, there was no difference in the 9HPT completion time between genders. Multivariate regression analysis identified the amplitude of the median compound muscle action potential (CMAP), age, and male gender as independent predictors of grip strength (adjusted R2 = 0.679), and amplitude of median CMAP and male gender as independent predictors of KP strength (adjusted R2 = 0.603). Velocity of median CMAP, amplitude of median sensory nerve action potential, and age were identified as independent predictors of 9HPT time (adjusted R2 = 0.329). Nerve conduction measurements were significantly related to hand-function test results, and CTS induced significant deficits in strength and performance of the affected hand.
