Abstract
Uvod: Sindrom karpalnog kanala (SKK) i cervikalna radikulopatija (CR) su najčešći uzrok senzomotorne disfunkcije na gornjim ekstremitetima. U kliničkoj praksi, ova dva stanja je često teško razlikovati, a često se javljaju i udruženo. U slučaju dijagnostičke sumnje, kao i pre lečenja pre svega operativnog, treba sprovesti elektromioneurografsko (EMNG) ispitivanje. Cilj: Ova studija ispituje kliničke karakteristike i EMNG nalaz kod pacijenata sa simptomima SKK i CR, sa ciljem da utvrdimo korelaciju između uputne (kliničke) i završne (EMNG potvrđene) dijagnoze, učestalost istovremenog prisustva SKK i CR, kao i korelaciju između prisustva tegoba i funkcionalnog statusa procenjenih na osnovu Levine (Boston) upitnika i EMNG nalaza kod ispitanih pacijenta. Metodologija: Ova studija preseka obuhvatila je 182 pacijenta (80,8% žena i 19,2% muškaraca), prosečne starosti 55.99±11.95 godina, upućena na EMNG ispitivanje sa uputnom dijagnozom SKK i/ili CR u Institut za rehabilitaciju u Beogradu u periodu od 01.01.-31.12.2015.godine, odnosno 267 simptomatskih ekstremiteta koji su ispunili EMNG kriterijume za SKK i CR. Svim ispitanicima izvršeno je standardno merenje brzina provodljivosti motornih i senzitivnih vlakana i latenci F-talasa n.medianus-a i n.ulnaris-a. Radi preciznije dijagnostike SKK izvršeno je uporedno merenje senzitivne latence n.medianus-a i n.unaris-a sa IV prsta. Elektromiografsko ispitivanje koaksijalnom iglenom elektrodom obuhvatilo je m.abductor pollicis brevis i reprezentativne mišiće za miotome C5 do C8/Th1. Svi pacijenti su samostalno popunili Levinov upitnik za procenu težine simptoma i funkcionalnog statusa. Ispitanici su, u odnosu na završnu dijagnozu, poređeni prema uputnoj dijagnozi, demografskim karakteristikama, subjektivnim tegobama, kliničkom nalazu, vrednostima skora Levine upitnika, i EMNG nalazu. U statističkoj obradi, za testiranje razlike korišćeni su parametarski (ANOVA) i nemaparametarski testovi (Kruskal-Wallis, Hi-kvadrat test), i naknadna testiranja sa Bonferroni korekcijom. Za ispitivanje povezanosti korišćena je Spirmanova i Pirsonova korelaciona analiza...
Introduction: Carpal tunnel syndrome (CTS) and cervical radiculopathy (CR) are the most common cause of sensory-motor dysfunction in the upper extremities. In clinical practice, these two conditions are often difficult to distinguish, and are often associated. In the case of diagnostic doubt, and before treatment, especially operative, electromyoneurographic (EMNG) examination should be conducted. Objective: This study examined the clinical characteristics and EMNG findings in patients with symptoms of CTS and CR, in order to determine the correlation between the referral (clinical) and final (EMNG confirmed) diagnosis, frequency of simultaneous presence of CTS and CR, as well as the correlation between the symptoms and functional status estimated using Levine (Boston) questionnaire and EMNG findings in the examined patient. Methods: This cross-sectional study included 182 patients (80.8% women and 19.2% men), mean age 55.99 ± 11.95 years, referred to the EMNG examination with the diagnosis of CTS and/or CR to the Institute for Rehabilitation in Belgrade in the period from 01.01-31.12.2015, respectively 267 symptomatic limbs who have met the EMNG criteria for CTS and CR. Median and ulnar standard nerve conduction studies (NCVs) were performed for all subjects. For more precise diagnosis of CTS, comparison median to unar sensitive latency measurements was conducted from IV digit. Needle EMG study included m.abductor pollicis brevis and representative muscles for miotomes C5 to C8/Th1. All patients completed the self-assessment Levin's questionnaire for symptom severity and functional status. Subjects were, depending on final diagnosis, compared in relation to thee referral diagnosis, demographic characteristics, subjective complaints, clinical findings, Levine questionnaire score values and EMG findings. In statistical analysis, we used parametric and nonparametric tests: ANOVA, Kruskal- Wallis, chi-square test, subsequent test with Bonferroni correction, Spirman and Pearson correlation analysis....
