This paper reports the case of an 11-year-old girl with painful pes cavus feet. The pain has diurnal fluctuation of symptoms; it is minimal after sleep and becomes more severe in the afternoon or evenign everyday, especially after walkign for long distances. Clinically, the child's feet had pes cavus deformity with hypertonia of the distal lower limbs. Radiological studies of the feet and the spine yielded essentially normal results. Diagnosis of Segawa disease was made in view of the diurnal fluctuation of symptoms that responded to dopa drugs. Both the foot pain and abnormal tone improved after drug treatment.

一例可用藥物治療的空凹足變形 (弓形足) - 瀨川症

任昌發、何相東、何遠芳

本文報導一例患痛楚弓形足11歲女童。痛楚於睡覺後最輕微,於午後或黃昏加劇,尤於長時間步行後。臨床檢查發現該病者雙足患有空凹足變形(弓形足)。神經糸統檢查發現下肢的肌肉緊張度比上肢高。脊椎及雙足的放射學檢驗均未有明顯異常結果。鑑於症狀隨晝夜波動並對dopa藥物有反應,臨床診斷為瀨川症。經藥物治療後,雙足痛楚及異常肌肉緊張度均有明顯改善。
