中文摘要 | 本研究目的在比較不同型式電流之舒適度。選用四種電流型式:連續性 和間歇性的低頻雙相波,間歇性的中頻蘇聯波及連續性的中頻干擾波,他們均具 有相同的40微米波寬和5O赫茲波頻,將這四種電流以隨意排列順序分別刺激40 位健康受試者的股四頭肌,當電流強度足以引起膝關節由彎曲30度舉起1公斤沙 袋至0度時.要求受試者在10公分長的比例刻度線(visal analog scale)上分別劃上四 種電流的舒適度。結果顯示間歇性的刺激均較連續性刺激的舒適度為佳,但是中 頻電流與低頻電流間的舒適度在相同的波寬下沒有明顯的差異,此外女性對電流 的舒適度較男性為差,而受試者間對不同電流的優先排列仍有許多變異性,是在 臨床應用上必須列入考慮的個別差異性。(中華物療誌1993;18(2):121-128) |
英文摘要 | The purpose of this study was to comparethe relative comfort levels of different electricalcurrents used in eliciting isotonic contractionsof quadriceps femoris muscle. The quadricepsfemoris muscles of 40 healthy subjects werestimulated by the intensity that was strongenough to extend the subject's knee from 30 to0 degrees of flexion against one-kilogramweight. Four 'different currents, with identicalstimulating pulse rate and pulse duration, wereused: continuous and intermittent biphasic currents, Russian current and interferential current. The relative comfort level of electrically elicited contraction for each current was determined for each subject using a IO-cm-longvisual analog scale. The results showed that asubject's perception of intermittent stimulation,either biphasic current or Russian current, wasmore comfortable than that of continuousstimulation. No whether middle or low frequency of currents, subjective comfort levelswere similar in the condition of the same shortpulse duration. (JPTA ROC 1993; 18(2):121-128) |
