Abstract
Carpal tunnel syndrome (CTS) is the most common nerve entrapment disorder worldwide. The epidemiology and risk factors, including family burden, for developing CTS are multi-factorial. Despite much research, its intricate pathophysiological mechanism(s) are not fully understood. An underlying subclinical neuropathy may indicate an increased susceptibility to developing CTS. Although surgery is often performed for CTS, clear international guidelines to indicate when to perform non-surgical or surgical treatment, based on stage and severity of CTS, remain to be elucidated. Neurophysiological examination, using electrophysiology or ultrasonography, performed in certain circumstances, should correlate with the history and findings in clinical examination of the person with CTS. History and clinical examination are particularly relevant globally owing to lack of other equipment. Various instruments are used to assess CTS and treatment outcomes as well as the effect of the disorder on quality of life. The surgical treatment options of CTS - open or endoscopic - offer an effective solution to mitigate functional impairments and pain. However, there are risks of post-operative persistent or recurrent symptoms, requiring meticulous diagnostic re-evaluation before any additional surgery. Health-care professionals should have increased awareness about CTS and all its implications. Future considerations of CTS include use of linked national registries to understand risk factors, explore possible screening methods, and evaluate diagnosis and treatment with a broader perspective beyond surgery, including psychological well-being.

Occupational and non-occupational risk factors correlating with the severity of clinical manifestations of carpal tunnel syndrome and related work disability among workers who work with a computer. Arh Hig Rada Toksikol 2023; 74:252-272. [PMID: 38146761 PMCID: PMC10750320 DOI: 10.2478/aiht-2023-74-3754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/01/2023] [Accepted: 12/01/2023] [Indexed: 12/27/2023] Open
Abstract
The contribution of certain occupational and personal factors to the development of carpal tunnel syndrome (CTS) is still uncertain. We investigated which specific occupational and non-occupational factors correlate with the level of clinical manifestations and work disability related to CTS. The study included 190 workers who work with a computer and have diagnosed CTS (100 men, 90 women, aged 20-65 years). Subjective experience of CTS-related impairments was assessed with the Symptom Severity Scale (SSS) and the Functional Status Scale (FSS) of the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ). The objective, neural impairments were tested with electrodiagnostics (EDX), whereas CTS-related work disability data were collected from medical records. We found a high inter-correlation between BCTQ, EDX, and work disability data. These also showed high correlations with certain occupational factors (duration of computer-working in months and hours spent daily in computer-working, certain ergonomic, microclimatic, and other occupational conditions) and non-occupational factors (demographic and lifestyle factors: nutritional status, diet, smoking, alcohol consumption, and physical activity). Despite its limitations, our study has identified occupational and non-occupational risk factors that can aggravate CTS and work disability, but which can also be improved with workplace and lifestyle preventive and corrective measures. More research is needed, though, to establish the possible causal relationships and the independent influence of each of those risk factors.

Association between carpal tunnel syndrome and the five-year incidence of anxiety disorder and depression in adults followed in general practices in Germany. J Psychosom Res 2023; 173:111469. [PMID: 37639884 DOI: 10.1016/j.jpsychores.2023.111469] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 08/15/2023] [Accepted: 08/16/2023] [Indexed: 08/31/2023]
Abstract
OBJECTIVE Little is known about the longitudinal relationship between carpal tunnel syndrome (CTS) and mental health. Therefore, this retrospective cohort study investigated the association between CTS and the five-year incidence of anxiety disorder and depression in adults from Germany. METHODS Data from the Disease Analyzer database (IQVIA) were used for the present study. Patients aged ≥18 years diagnosed for the first time with CTS in one of 1284 general practices in Germany in 2005-2020 were included (index date). Individuals without CTS were matched to those with CTS using a propensity score based on age, sex, the mean number of consultations per year during the follow-up, and the index year. In people without CTS, the index date was a randomly selected consultation in 2005-2020. RESULTS There were 75,135 patients with and 75,135 patients without CTS included in the study (mean [SD] age 57.2 [16.5] years; 59.7% women). Within five years of the index date, the incidence of anxiety disorder was 3.9% and 3.6% in the group with and the group without CTS, respectively (log-rank p-value<0.001), while figures for depression were 14.8% and 11.5% (log-rank p-value<0.001). These findings were corroborated in the Cox regression analyses adjusted for multiple physical conditions, as CTS was associated with anxiety disorder (HR = 1.14, 95% CI = 1.08-1.21) and depression (HR = 1.29, 95% CI = 1.25-1.33) in the overall sample. CONCLUSION CTS was associated with an increased incidence of anxiety disorder and depression in Germany. Further research should identify the mediators involved in these relationships.
