RESUMO

INTRODUCTION: Widespread pain may be related to psychosocial aspects in several musculoskeletal conditions, but the literature on carpal tunnel syndrome (CTS) is scarce. OBJECTIVE: To determine the relationship between pain extent and psychological factors (catastrophizing, kinesiophobia, anxiety symptoms, and depression) in people with CTS. METHODS: A cross-sectional study was conducted. The independent variables were: pain intensity, disability (QuickDASH), duration of symptoms, anxiety and depressive symptoms, catastrophizing, and kinesiophobia. The main outcome was: pain extent (% of total area and categories "pain within the median nerve-innervated territory" versus "extra-median nerve pain"). Correlation analysis was performed using Spearman's correlation coefficient. A linear regression model and binary logistic regression (both with forward selection) were performed to determine the main predictors of pain extent. RESULTS: Forty-eight participants were included. A moderate positive correlation was found between catastrophizing (r = 0.455; p = 0.024) and disability (r = 0.448; p = 0.024) with total pain extent area. Regression models indicated that catastrophizing explained 22% of the variance in the pain extent (ß = 0.003; 95% CI: 0.002-0.005), while kinesiophobia was the variable that best explained the distribution of pain in the extra-median territory (R2 Nagelkerke = 0.182). Null or weak correlations were found for the rest of the associations. CONCLUSION: Catastrophizing and kinesiophobia were the main indicators of pain extent in people with CTS. Clinicians are advised to use specific questionnaires to check for the presence of catastrophizing or kinesiophobia in people with CTS and wider pain extension.

RESUMO

Transverse carpal ligament (TCL) opening is the treatment of choice for carpal tunnel syndrome. However, complications such as loss of grip strength and anterior displacement of the median nerve are described as common complications associated with this technique. Thus, techniques that reconstruct or extend TCL are described to reduce the incidence of these complications. OBJECTIVE: To evaluate the effectiveness of TCL enlargement through Z-plasty and the reduction of complications by comparing it with the complete opening of the ligament. MATERIALS AND METHODS: A prospective and randomized intervention study was conducted in 56 patients. They were divided into 2 groups: 1) complete opening of TCL 2) TCL enlargement via Z-plasty. We evaluated grip strength, sensitivity, and functional evaluation using the QuickDASH questionnaire. RESULTS: There was no statistically significant difference in the improvement of scores with QuickDASH between the two techniques. The sensitivity test was better in patients subjected to TCL enlargement, whereas grip strength increased in the group subjected to complete TCL opening. CONCLUSION: According to the results of this study, the complete opening of the TCL showed no reduction in grip strength, although it showed inferior recovery to postoperative sensitivity. Both techniques were equivalent in functional improvement. Thus, Z-plasty showed no identifiable benefits for TCL enlargement. Level of Evidence III, Randomized Clinical Trial.

A abertura completa do ligamento transverso do carpo (LTC) é o tratamento de escolha para a síndrome do túnel do carpo. No entanto, complicações como perda de força de preensão e deslocamento anterior do nervo mediano são complicações comuns associadas a essa técnica. Assim, descrevem-se técnicas que reconstroem ou alargam o LTC visando reduzir a incidência dessas complicações. Objetivo: Avaliar a efetividade do alargamento do LTC através de Z-plastia e a diminuição das complicações, comparando a técnica com a abertura completa do ligamento. Métodos: Realizou-se um estudo de intervenção, prospectivo e randomizado com 56 pacientes. Estes foram divididos em dois grupos: 1) abertura completa do LTC e 2) alargamento do LTC através de Z-plastia. Avaliamos força de preensão e sensibilidade e realizamos avalição funcional por meio do questionário Quick Disabilities of Arm, Shoulder and Hand (QuickDASH). Resultados: Não houve diferença estatisticamente significante na melhora dos escores entre as duas técnicas. O teste de sensibilidade teve melhores resultados nos pacientes submetidos ao alargamento do LTC, enquanto a força de preensão teve maior acréscimo no grupo submetido à abertura completa do LTC. Conclusão: A abertura completa do LTC não levou à redução da força de preensão, apesar de ter se mostrado inferior na recuperação da sensibilidade no pós-operatório. As duas técnicas foram equivalentes na melhora funcional. Dessa forma, não encontramos benefícios identificáveis na realização da Z-plastia para alargamento do LTC.

RESUMO

Objective Given the divergence of opinions on the need for complementary tests such as ultrasonography (US) and electroneuromyography (ENMG) for the diagnosis of carpal tunnel syndrome (CTS), we aimed to elucidate which of them presents greater accuracy for the confirmation of the presence or not of this condition. Methods A total of 175 patients from a hand surgery outpatient clinic were clinically evaluated, and the results of clinical trials (Tinel, Phalen and Durkan), US (normal or altered), and ENMG (normal, mild, moderate and severe) were noted, crossed, and submitted to a statistical analysis to verify the agreement between them. Results with the sample had a mean age of 53 years, with a prevalence of female patients (159 cases). Of the patients with positive clinical test, 43.7% had normal US and 41.7% had no alterations on the ENMG. Negative results were found on the Tinel in 46.9%, on the Phalen in 47.4%, and on the Durkan in 39.7%. In the crossing between the results of the ENMG and those of the other diagnostic methods, there was little statistical agreement between them. Conclusion There was no agreement between the results of the clinical examinations, the US and the ENMG in the diagnosis of CTS, and there is no clinical or complementary examination for CTS that accurately determines the therapeutic approach. Level of Evidence IV, Case Series.

RESUMO

SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of radial extracorporeal shock wave therapy on pain, functionality, and electrophysiological measurements in carpal tunnel syndrome. METHODS: Between June 2021 and January 2022, a total of 66 wrists in 45 participants with mild-to-moderate carpal tunnel syndrome were included in this double-blind, prospective, randomized, placebo-controlled study. Patients were randomized into two groups, namely, the radial extracorporeal shock wave therapy (group 1, n=33) and the sham radial extracorporeal shock wave therapy (group 2, n=33). Night splints and tendon nerve gliding exercises were given to all participants. The participants were evaluated at baseline and the first month after treatment. Participants were evaluated using a visual analog scale, the Boston Carpal Tunnel Questionnaire, Leeds Neuropathic Symptom and Symptom Assessment, and electrophysiological examinations. RESULTS: A total of 37 participants (a total of 55 wrists, radial extracorporeal shock wave therapy n=27, and sham radial extracorporeal shock wave therapy n=28) completed the study. After the intervention, there was a significant decrease in visual analog scale values (p<0.001) and a significant increase in Boston Carpal Tunnel Questionnaire scores (p<0.001) and Leeds Neuropathic Symptom and Symptom Assessment scores (p<0.001). In electrophysiological measurements, there was a significant decrease in median nerve sensory (p=0.002) and motor (p=0.003) distal latency, and a significant increase in median nerve sensory conduction velocity (p=0.026) was found in the radial extracorporeal shock wave therapy group. CONCLUSION: This study shows that radial extracorporeal shock wave therapy has positive effects on pain, functionality, and electrophysiological measurements for mild-to-moderate carpal tunnel syndrome 1 month after application.

RESUMO

ABSTRACT Carpal tunnel syndrome (CTS) is the most common mononeuropathy caused by entrapment of the median nerve at the wrist. Common treatment options for CTS include oral analgesics, splinting, hand therapy, local injections with steroids or surgery. Objective: The aim of the present study was to assess the short-term clinical and electrophysiological outcomes of local corticosteroid injection (LCI) in patients with symptomatic CTS. Methods: Electrophysiological parameters were evaluated before and three months after LCI. Moreover, the Numeric Rating Scale (NRS), the Boston Symptom Severity Scale (SSS) and the Functional Status Scale (FSS) were administered before and after the injection. A mixture of 1 mL (40 mg) of methylprednisolone and 1 mL of 0.5% bupivacaine were injected blindly on the volar side of the forearm between the tendons of the radial carpal flexor muscle and long palmar muscle. Results: A total of 25 patients (45 hands) were enrolled in the study. Twenty women and five men with a mean age of 49.28 ± 11.37 years were included. A statistically significant difference was noted for improvement of sensory conduction velocities, sensory peak latency, and motor distal latency (p = 0.001) after LCI. A significant difference was recorded between pre- and post-injection for NRS, SSS and FSS scores (p = 0.000). Conclusion: Local corticosteroid injection for CTS provides a short-term improvement in neurophysiological and clinical outcomes such as pain intensity, symptom severity and functional ability.

RESUMO A síndrome do túnel do carpo (STC) é a mononeuropatia mais comum causada pelo aprisionamento do nervo mediano no punho. Opções comuns de tratamento para STC incluem analgésicos orais, splinting, terapia de mão, injeções locais com esteroides ou cirurgia. Objetivo: O objetivo do presente estudo foi avaliar os resultados clínicos e eletrofisiológicos de curto prazo da injeção de corticosteroide local (ICL) em pacientes com STC sintomática. Métodos: Os parâmetros eletrofisiológicos foram avaliados antes e três meses após a ICL. Além disso, a Escala Numérica de Avaliação (NRS), a Escala de Gravidade de Sintomas de Boston (BSS) e a Escala de Status Funcional (FSS) foram administradas antes e após a injeção. Uma mistura de 1 ml (40 mg) de metilprednisolona e 1 ml de bupivacaína a 0,5% foi injetada cegamente no lado do antebraço entre os tendões do músculo flexor radial do carpo e o músculo palmar longo. Resultados: Um total de 25 pacientes (45 mãos) foi incluído no estudo. Vinte mulheres e cinco homens com idade média de 49,28 ± 11,37 anos foram incluídos. Foi observada diferença estatisticamente significante para melhora das velocidades de condução sensitiva, latência de pico sensorial, latência motora distal (p = 0,001) após a ICL. Uma diferença significativa foi registrada entre pré e pós-injeção para os escores NRS, BSS e FSS (p = 0,000). Conclusão: A ICL para STC fornece uma melhoria a curto prazo em resultados neurofisiológicos e clínicos, tais como intensidade da dor, gravidade dos sintomas e capacidade funcional.

RESUMO

Carpal Tunnel Syndrome is the most common compressive neuropathy in the general population, and it may lead to disabling symptoms and significant functional limitation. This systematic review covered Pubmed, Medline, Embase, Cochrane, CINAHL, LILACS, and SCIELO databases, with no time or language delimitations. The PICO strategy defined the search strategy with keywords extracted from the Medical Subjects Headings, and the quality of the studies was evaluated by the Agency for Healthcare Research and Quality (AHRQ) scale. Overall, 857 studies were identified, of which only 10 fulfilled the inclusion criteria. Despite the good results shown, a noticeable heterogeneity was observed among the studies included, associated with methodological discrepancy and to limited sample size in a few of them. Four studies showed no correlation between electrophysiological findings and clinical symptoms and signs, whereas three could demonstrate such association and other three studies had equivocal results. Other studies are necessary, with better methodological standards and more homogeneous and precise evaluations, so as to improve the level of scientific evidence

RESUMO

Background: Carpal tunnel syndrome (CTS) represents 90% of entrapment neuropathies. Severity may be greater in older patients. Aim: To describe the electrophysiological findings in adult patients with CTS and determine if severity is related to age. Material and Methods: Descriptive and retrospective study of electrophysiological findings in patients over 18 years of age with clinical suspicion of CTS, studied between January 2011 and December 2015. Neurophysiological severity was classified in 3 grades, comparing them by age, gender and laterality. Results: Of 1156 patients subjected to electrophysiological studies due to a clinical suspicion of CTS, 690 (60%) had electrophysiological features of the disease. In 274 patients (24%) the compromise was mild, in 162 (14%) it was moderate and in 254 (22%) it was severe. There was a positive association between age and CTS severity (p < 0.01). Severity was significantly greater in males than females (p < 0.01). Bilateral CTS was present in 471 patients (68%), which was associated with increased age and severity (p < 0.01). Conclusions: Electrophysiological severity in CTS increases with age. Other factors associated with higher severity are male gender and bilateral disease.

RESUMO

INTRODUCTION: Focal peripheral neuropathy of the median nerve is mainly caused by a traumatic event or pressure, but it may also be produced by systemic illnesses. Among the latter, leprosy is a rare cause. METHODS: Six cases of isolated median neuropathy as the first sign of leprosy were selected from patients with an exclusively neurological complaint as the initial symptom. The patients, evaluated at the National Leprosy Reference Center in Rio de Janeiro, Brazil, followed routine and specialized procedures. RESULTS: Three of the patients had pure neural leprosy, and 3 had skin lesions. Clinical median nerve function impairment was confirmed by neurophysiological testing and histopathology. Both mononeuritis and mononeuritis multiplex were observed. CONCLUSIONS: This case series demonstrates an additional form of presentation of leprosy, which, if not diagnosed and treated in time, may lead to permanent disability.

RESUMO

OBJECTIVE: To evaluate the pressure perception thresholds on the pulp of two fingers (index and little fingers), among a Brazilian population with no nerve injury or neuropathy. METHODS: We used the Pressure-Specified Sensory Device (a computerized device) to derive static and dynamic normal pressure perception thresholds and two-point discrimination distances. RESULTS: We tested finger sensitivity on 30 volunteers. Significance analyses were performed using the Student t test. The mean values (g/mm(2)) for static one and two-point pressure thresholds (s1PD, s2PD) and dynamic one and two-point discrimination (m1PD, m2PD) in the dominant index finger were: s1PD = 0.4, m1PD = 0.4, s2PD = 0.48, m2PD = 0.51. CONCLUSION: There was no significant difference in sensitivity between the dominant and nondominant hands.

RESUMO

OBJECTIVE: Evaluate the post-operative treatment of CTS, using the LLLT. METHOD: We prospectively evaluated 58 patients with CTS, randomly divided into two groups: treatment with LLLT (Group 1) and placebo (Group 2). A 830 nm gallium-aluminum-arsenic laser was used, with a power of 30 mW. RESULTS: There was female predominance in both groups. The mean age of the patients in Group 1 was 44.3 years and in Group 2, 51.9 years. The average duration of disease progression was around two years in both groups. The average time elapsed since discharge from treatment was 3.6 months in both groups, and fewer patients had postoperative complaints in Group 1 than in Group 2. At the end of the treatment, in Group 1, 29.41% of the patients presented electromyographic abnormalities, while in Group 2, 63.64% of the patients had abnormalities, after six months. CONCLUSION: This was an initial study on adjuvant therapy using postoperative LLLT on CTS. The method presented was sufficient for postoperative evaluation of the patients in this study. Patients undergoing LLLT after surgery for CTS were benefited and had better functional outcomes than shown by the control group. The technique was effective and did not have any adverse effects on the patients studied.
