Subclinical pronator syndrome in patients with carpal tunnel syndrome: An electrophysiological study

INTRODUCTION: Carpal tunnel syndrome (CTS) is the most common entrapment syndrome of median nerve causing frequent disability especially among working populations. Boston Carpal Tunnel Questionnaire and Electrophysiological study helps in detecting and aiding in the diagnosis of CTS and helps in determining level of improvement after surgical release of carpal tunnel. OBJECTIVES: To assess functional outcome of patients with Carpal Tunnel Syndrome after surgery as assessed by Boston Carpel Tunnel Questionnaire and Electrophysiological study. METHODS: A prospective observational study conducted over a period of one year (January 2017 to January 2018). The study was conducted among consecutive 31 electrophysiological conrmed carpal tunnel syndrome attending the outpatient department of Physical Medicine and Rehabilitation, Government Medical College, Thiruvananthapuram. All patients underwent open carpal tunnel release. Functional outcome was assessed using Boston Carpal Tunnel Questionnaire (BCTQ) both preoperatively and at interval of 3 weeks, 6weeks and 3 months postoperatively. Electrophysiological study assessed using nerve conduction study both preoperatively and 3 weeks post operatively. Data was entered in Microsoft excel and analyzed using SPSS statistical software. RESULTS: The study involves 31 conrmed cases of Carpal tunnel syndrome patients. Mean Boston Carpal Tunnel Questionnaire (BCTQ) score preoperatively was 58.52 ± 12.73 which was markedly improved postoperatively at 3weeks with mean score of 29.77±6.68. At 6 weeks and 3 month follow up period it was reduced respectively to mean score of 23.94±4.23 and 22.94±4.62. Preoperative NCS shows decreased conduction velocity with mean nerve sensory velocity (NSV) score 21.51±8.19 and mean nerve motor velocity (NMV) score of 20.72±8.81 which statistically improved following surgery with mean NSV score of 32.04±9.01 and mean NML score of 33.78±8.1. Correlation between pre- and post-operative BCTQ and NCS parameters shows positive correlation with latency and negative correlation with amplitude and conduction velocity. Increased latency and decreased conduction velocity associated with higher BCTQ score with signicant 'p' value (p<0.05). CONCLUSION: There is statistically signicant improvement of functional outcome following carpal tunnel release surgery assessed through Boston Carpal Tunnel Questionnaire and Electrophysiological ndings

The Right

The first clinical case of carpal tunnel syndrome (CTS) in Cuban HIV-infected patient was described, and the scientific literature indexed in: PUBMED/MEDLINE, LILACS and BIREME were revised. The case presented was a male with HIV infection without preceding opportunistic illnesses, CD4+ T cell count over 200 cells/mm3 and clinical symptoms of pain, tingling and numbness in the right hand and wrist for three months. The electrophysiological study was compatible with CTS. The pharmacological treatment did not modify the symptoms and the patient received specific surgical treatment with absolute resolution of symptoms. CTS is a compressive neuropathy that can occur in HIV-positive individuals with as similar frequency as in the general population. The association between HIV infection and CTS is scarcely described in the medical scientific literature and probably does not represent a different phenomenon from what happens in the HIV-negative population. Nevertheless, its clinical recognition among other neurological and muscle-skeletal manifestations in HIV-infected patients is important.
