Carpal tunnel syndrome and the use of computer mouse and keyboard: a systematic review.

ABSTRACT:

Background

This review examines evidence for an association between computer work and carpal tunnel syndrome (CTS).

Methods

A systematic review of studies of computer work and CTS was performed. Supplementary, longitudinal studies of low force, repetitive work and CTS, and studies of possible pathophysiological mechanisms were evaluated.

Results

Eight epidemiological studies of the association between computer work and CTS were identified. All eight studies had one or more limitation including imprecise exposure and outcome assessment, low statistical power or potentially serious biases. In three of the studies an exposure-response association was observed but because of possible misclassification no firm conclusions could be drawn. Three of the studies found risks below 1. Also longitudinal studies of repetitive low-force non-computer work (n = 3) were reviewed but these studies did not add evidence to an association. Measurements of carpal tunnel pressure (CTP) under conditions typically observed among computer users showed pressure values below levels considered harmful. However, during actual mouse use one study showed an increase of CTP to potentially harmful levels. The long term effects of prolonged or repeatedly increased pressures at these levels are not known, however.

Conclusion

There is insufficient epidemiological evidence that computer work causes CTS.

Project description:PurposeGabapentinoids are commonly prescribed for the treatment of neuropathic pain but are not recommended for the primary treatment of carpal tunnel syndrome (CTS). We sought (1) to investigate the preoperative use of gabapentinoids for the treatment of CTS and (2) to determine whether preoperative exposure is associated with persistent gabapentinoid and opioid use after carpal tunnel release.MethodsWe performed a retrospective cohort study using IBM MarketScan Research Databases (2010-2017) of patients who did not fill a gabapentinoid or opioid prescription within 3 months of a new CTS diagnosis undergoing surgical release. Our primary outcomes included preoperative gabapentinoid prescription fills associated with CTS and persistent prescription fills of gabapentinoids and opioids at 91 to 180 days after surgery. Multivariable logistic regression models were used to evaluate the association between patient-level factors and persistent gabapentinoid and opioid use.ResultsOf the 56,593 patients without a previous gabapentinoid or opioid prescription prior to diagnosis of CTS, 3,474 patients (6%) filled a gabapentinoid prescription before carpal tunnel release. Overall, 835 patients (24% of the preoperative users) continued to fill gabapentinoid prescriptions at 91 to 180 days after surgery. Of the preoperative gabapentinoid users, 20% (702 patients) continued to fill opioid prescriptions at 91 to 80 days after release. After adjusting for patient characteristics, preoperative gabapentinoid use was associated with increased odds of persistent postoperative gabapentinoid use (preoperative gabapentinoid, 22% adjusted probability; 95% confidence interval [95% CI], 20.3%-23.0%, no preoperative gabapentinoid use, 1%; 95% CI, 1.2%-1.4%) and persistent postoperative opioid use (preoperative gabapentinoid, 18% adjusted probability; 95% CI, 17%-20%), no preoperative gabapentinoid, 9%; 95% CI, 8.6%-9.1%).ConclusionsDespite a lack of evidence to support the use of gabapentinoids for CTS, 6% of patients are prescribed a gabapentinoid prior to surgery, and prolonged use is common. Given the effectiveness of surgical release and the risks associated with gabapentinoids, greater attention is needed to ensure that gabapentinoids are prescribed appropriately, avoided when possible, and stopped after surgery.Type of study/level of evidencePrognostic II.

Project description:BackgroundCarpal tunnel syndrome is a common disorder in hand surgery practice. Both surgical and conservative interventions are utilized for the carpal tunnel syndrome. Although certain indications would specifically indicate the need for surgery, there is a spectrum of patients for whom either treatment option might be selected. The purpose of this systematic review was to compare the efficacy of surgical treatment of carpal tunnel syndrome with conservative treatment.MethodsWe included all controlled trials written in English, attempting to compare any surgical interventions with any conservative therapies. We searched Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2010), MEDLINE (1980 to June 2010), EMBASE (1980 to June 2010), PEDro (searched in June 2010), international guidelines, computer searches based on key words and reference lists of articles. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Weighted mean differences and 95% confidence intervals for patient self-reported functional and symptom questionnaires were calculated. Relative risk (RR) and 95% confidence intervals for electrophysiological studies and complication were also calculated.ResultsWe assessed seven studies in this review including 5 RCTs and 2 controlled trials. The methodological quality of the trials ranged from moderate to high. The weighted mean difference demonstrated a larger treatment benefit for surgical intervention compared to non surgical intervention at six months for functional status 0.35( 95% CI 0.22, 0.47) and symptom severity 0.43 (95% CI 0.29, 0.57). There were no statistically significant difference between the intervention options at 3 months but there was a benefit in favor of surgery in terms of function and symptom relief at 12 months (0.35, 95% CI 0.15, 0.55 and 0.37, 95% CI 0.19 to 0.56). The RR for secondary outcomes of normal nerve conduction studies was 2.3 (95% CI 1.2, 4.4), while RR was 2.03 (95% CI 1.28 to 3.22) for complication, both favoring surgery.ConclusionBoth surgical and conservative interventions had treatment benefit in carpal tunnel syndrome. Surgical treatment has a superior benefit, in symptoms and function, at six and twelve months. Patient underwent surgical release were two times more likely to have normal nerve conduction studies but also had complication and side effects as well. Given the treatment differential and potential for adverse effects and that conservative interventions benefitted a substantial proportion of patients, current practice of a trial of conservative management with surgical release for severe or persistent symptoms is supported by evidence.
