中文摘要:
目的：为得到电刺激强度与骨胳肌肌力之间的关系。
方法： 应用扣带式肌力传感器及电生理仪对12只兔小腿三头肌肌张力进行测定。
结果：在3～10mA的电流强度范围内,肌力随刺激方波波宽的增加而加大,10mA,2ms时为最大(1.757±2.165kg);刺激量为3～50V电压范围内,肌力大小同样依赖于波宽宽度,波宽2ms时达最大(1.750±0.808kg).
结论：为得到某肌张力应在有效的范围内选择电刺激参数。非负重状态免三头肌最大肌张力近似于其本身体重。 |

ABSTRACT
Aim: To obtain the relationship between skeletal muscle tension and intensity of electric stimulus.
Methods: The muscle tension of triceps of shank in 12 rabbits was determined with belt buckle ten- sile transducer and electric physiological instrument.
Results: As the range of the current intensity was in 3～ 10mA, the muscle tension was increased along with the increase of the square wave duration and the maxi- mum of muscle tension (1.757±0. 2165kg) was at 10mA and 2ms. As the amount of stimulus in the range of 3～50V, the muscle tension was also dependent upon the wave duration and its maximum (1.750± 0. 808kg)at 2ms.
Conclusion: It is suggested that the electric stimulus parameter in the range of effective electric pulse stimulation should be selected for obtaining a muscle tension. The maximal muscle tension of rabbit’s triceps at non-loading condition is similar to its body weight. |
