Diagnostic Contradictions in Carpal Tunnel Syndrome.

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 Objetivo Diante da divergência sobre a necessidade de exames complementares, como ultrassonografia (US) e eletroneuromiografia (ENMG) para o diagnóstico da síndrome do túnel do carpo (STC), objetivamos elucidar qual deles apresenta maior precisão na confirmação da presença ou não desta afecção. Métodos Um total de 175 pacientes de um ambulatório de cirurgia da mão foram avaliados clinicamente, e os resultados dos testes clínicos (Tinel, Phalen e Durkan), da US (normal ou alterada) e da ENMG (normal, leve, moderada e grave) foram anotados, cruzados, e submetidos a análise estatística para verificar a concordância entre eles. Resultados A idade média da amostra era de 53 anos, sendo prevalente o sexo feminino (159 casos). Dos pacientes com teste clínico positivo, 43,7% apresentavam US normal, e 41,7%, ENMG sem alterações. Foram encontrados resultados negativos no Tinel em 46,9% no Phalen em 47,4%, e no Durkan em 39,7%. No cruzamento entre a ENMG e os demais métodos diagnósticos, houve pouca concordância estatística. Conclusão Não houve concordância entre os resultados dos exames clínicos, da US e da ENMG no diagnóstico da STC, e não há exame clínico ou complementar para STC que determine a conduta terapêutica com precisão. Nível de Evidência IV, Série de Casos.

Electrodiagnostic Testing Characteristics of Diabetic People with Carpal Tunnel Syndrome.

Objective The present study aimed to correlate electroneuromyography (ENMG) findings in diabetic and nondiabetic subjects with carpal tunnel syndrome (CTS). Methods In total, 154 patients were evaluated in a hand surgery outpatient clinic. All ENMG tests were bilaterally performed by a single neurologist. Qualitative variables were described for all patients with CTS according to their diabetic status, and the chi-squared test was used to reveal any association. A joint model was adjusted to determine the influence of diabetes on ENMG severity in CTS patients. Results The sample consisted of 117 women and 37 men, with an average age of 56.9 years old. Electroneuromyography demonstrated bilateral CTS in 82.5% of the patients. Diabetes was identified in 21.4% of the cases. Severe ENMG was prevalent. Conclusion There was no association between diabetes and ENMG severity in patients with CTS. Level of evidence IV, case series.

Resumo Objetivo O presente trabalho teve por objetivo verificar se existe correlação entre a síndrome do túnel do carpo (STC) e eletroneuromiografia (ENMG) de pacientes diabéticos e não diabéticos. Métodos Foram avaliados 154 pacientes em um ambulatório de cirurgia da mão. Todas as ENMGs avaliadas foram realizadas por um único neurologista, bilateralmente. As variáveis qualitativas foram descritas para todas as pessoas em acompanhamento devido à STC segundo a presença de diabetes e foi verificada a associação com uso do teste qui-quadrado. Foi ajustado o modelo conjunto para verificar a influência da diabetes na gravidade da ENMG em pacientes com STC. Resultados Foram incluídos no presente estudo 117 mulheres e 37 homens, com média de idade de 56,9 anos. Eletroneuromiografia demonstrando STC bilateral foi observada em 82,5% das pessoas. Pessoas diabéticas foram identificadas em 21,4% dos casos. Eletroneuromiografia com padrão grave foi prevalente. Conclusão Não houve associação entre a presença de diabetes e a gravidade da ENMG em pessoas com STC. Nível de evidência IV, série de casos.

Is there an association between the Hand Diagram and Electrodiagnostic Testing for Carpal Tunnel Syndrome?

Objective Verify if there is an association between the hand diagram of paresthesia (HDP) and the results of electroneuromyography (ENMG) in the diagnosis of carpal tunnel syndrome. Methods A total of 92 people filled in a schematic drawing of the hand with the exact location of the paresthesia (167 hands). The main author classified the diagrams according to the criteria of Katz et al. 5 The results of the HDP were crossed with the positive results of ENMG for the diagnosis of carpal tunnel syndrome. Results The possible pattern of the HDP was prevalent both in isolation and after crossing with the degrees of ENMG. Conclusion There was no association between the HDP and ENMG in the diagnosis of carpal tunnel syndrome.

Is there an association between electroneuromyography and ultrasound in the diagnosis of carpal tunnel syndrome?

Objective To verify whether there is an association between the results of the severity in electroneuromyography and the positivity in ultrasound in the diagnosis of carpal tunnel syndrome. Methods Sixty-eight patients were included in the study, 61 women and 7 men, with a mean age of 54.4 years. The ultrasound results (positive or negative) were crossed with the results of electroneuromyography (mild, moderate or severe), and the existence of association was verified. Results One hundred and thirty-six hands with suspicion or symptoms of carpal tunnel syndrome were evaluated. Positive ultrasound diagnosis was observed in 72 hands and negative in 64; 123 hands presented positive electroneuromyography for carpal tunnel syndrome, and there were 13 negative results. The severe degree in electroneuromyography was prevalent. Conclusion There was a statistically significant association between electroneuromyography and ultrasonography ( p < 0.05), and ultrasound positivity was higher for more severe levels of carpal tunnel syndrome given by electroneuromyography.

Prevalence of Anxiety and Depression Symptoms in People with Carpal Tunnel Syndrome.

Objectives To demonstrate the prevalence of depression and anxiety symptoms in patients with carpal tunnel syndrome treated at a hand surgery outpatient clinic and to describe the clinical and epidemiological characteristics of this population. Methods People diagnosed with carpal tunnel syndrome at the initial visit were evaluated over a 6-month period for data collection. Clinical and epidemiological characteristics were noted, and patients diagnosed with anxiety and/or depression were evaluated. Results In total, 101 people had carpal tunnel syndrome, including 38 diagnosed with depression and 29 with anxiety. Most patients were low-income women, with elementary school-level education. More than half of the patients had at least one associated systemic comorbidity. Conclusion Independent characteristics that statistically influenced anxiety and depression symptoms in patients with carpal tunnel syndrome were gender, smoking, and family income ( p < 0.05).
