Lumbosakral radikülopati olgularında elektromiyografinin tanı değeri

Amaç: Bu çalışmanın amacı lumbosakral, radikülopatili hastalarda iğne elektromiyografisi (EMG) ve refleks cevapların tanıdaki değerini araştırmaktır. Yöntem: Klinik, radyolojik ve cerrahi olarak ispatlanmış L5 ve S1 kök lezyonu olan 27 hastada iğne EMG'si, F ve H refleksleri çalışıldı. Bulgular: Paraspinal ve ekstremite kaslarına yapılan iğne EMG'si 27 hastanın 24'ünde (% 88) radikülopati tanısı ile uyumlu idi. Hastaların % 29'unda F, % 50'sinde H refleks anormalliği mevcuttu. Yirmiyedi hastanın 25'inde paraspinal kaslar değerlendirildi ve 17'sinde (% 68) bu kaslarda da elektrofizyolojik anormallik saptandı. Sonuç: EMG ve refleks çalışması lumbosakral diskopatili hastalarda yüksek oranda tanısal değere sahiptir.

Diagnostic utility of electromyography in patients with lumbosacral radiculopathy

Objective: The aim of this study was to investigate the diagnostic utility of needle electromyography (EMG) and reflex studies in patients with lumbosacral radiculopathies. Methods: Needle EMG, F wave and H reflex were studied in 27 patients with clinically, radiologically and surgically proven L5 or S1 root lesions. Results: Needle EMG studies in the paraspinal and limb muscles confirmed a radiculopathy in 24 (88%) of 27 patients. Twenty-nine percent of the patients had F reflex and 50% had H reflex abnormality. Seventeen (68%) of 25 patients in whom paraspinal EMG could be performed had electrophysiologic abnormality in paraspinal muscles. Conclusion: EMG and reflex responses have high diagnostic value in patients with lumbosacral radiculopathies.
