Characteristics of surface electromyography and work load of the forearm extensors in repetitive wrist extending 重复性伸腕作业劳动负荷与前臂伸肌的表面肌电特征
On examination , there were red - brown papules and plaques on the extensor knees , elbows , and dorsal hands 查体见双膝、双肘伸侧及双手背侧多发的红棕色丘疹及色斑。
The forces involved in extensor mechanism : the quadriceps muscle force , tension of patellar tendon and patellofemoral joint reaction force , are computed 结果表明，髌骨适当后倾对增强伸膝机构功能有利。
The second , third , and fourth metatarsophalangeal joints are reached by a dorsolateral incision parallel to the corresponding extensor tendon ( fig . 1 - 25 ) 第二、三、四跖趾关节手术可采用平行于相应的趾伸肌腱的背外侧切口(图1 - 25 ) 。
