尺神經肘溝症候群以第一背側骨間肌與外展小指肌為記錄位置之比較研究
Comparative Study of Recording Electrode on First Donrsal Interosseous and Abductor Digiti Minimi in Cubital Tunnel Syndrome
摘要
尺神經肘溝症候群是周邊神經壓迫申相當常見的，神經傳導檢查顯示尺神經於越肘的運動神經傳導速度減慢是診斷的主要依據。本研究的日的即在比較同時於第一背側骨問肌〈FDI〉與外展小指肌〈ADM〉兩處作表面電極記錄，其診斷尺神經肘溝症候群的敏感度。共檢查724個肝溝症候群患者的上肢(實驗組〉及52個正常上肢(對照組，又分為大於30歲及小於30歲兩組〉。分別於手腕，肘下及肝上三個尺神經那位給予超大的電刺激，同時於FDI及ADM兩處作表面電極記錄。可測得三組之FDI與ADM肘下及越肘的神經傳導數值，再將此兩值之差值作三組之間的統計考驗。 結果顯示實驗組與兩對照組問於FDI與ADM處所得的肘下及越肘神經傳導速度的差值都有顯著性的差異。此外，更進一步的探討發現使用FDI實驗組之數值與對照組之數值之差異性要比用ADM處來的大，顯示其對尺神經肘溝症候群之診斷更為敏感。

Cubital tunnel syndrome is the common entrapment/compression mononeuropathy diagnosed in the electromyography (EMG) laboratory. Slowing of the elbow segment's motor conduction velocity is a primary identifier of anab normality. The purpose of this study is to compare the difference of the conduction velocity with recording in First Dorsal Interosseous (FDI) and Abductor digiti minimi in cubital tunnel syndrome (CuTS). The subjects included three groups: one study group consist of 24 upper limbs with CuTS which were diagnosed by NCS & needle EMG.. Another two control groups consist of 52 normal upper limbs which were fmther divided into older group (＞30 years old) included 27 upper limbs & younger group (＜30 years old) included 25 upper limbs. We delivered supramaximal stimulations over the wrist, below elbow, and above elbow on the ulnar nerve and obtained the data of segmental CV of below elbow (BE) and across elbow (AE) from FDI and ADM. The differences of segmenlal CV between BE and AE was compareds in three groups. The results revealed that there is significant difference between study group and two control groups with recording in FDI and ADM. The post-comparison studyshowed that recording from FDI is more sensitive in diagnosing CuTS than that from ADM. Based on this study, if cubital tunnel syndrome is corsidered.
