The utility model belongs to the technical field of medical devices, in particular to a low back muscle strength detection device, which comprises a seat, a fixing piece and a muscle strength tester. A cylinder seat is installed on the seat, a cylinder is installed on the cylinder seat, a step cushion block is arranged below the seat, the telescopic shaft of the cylinder is connected with the step cushion block, the fixing piece comprises a mounting plate, and a plurality of straps are installed on the mounting plate, The free ends of the straps are equipped with connecting buckles, the muscle strength tester is installed on the mounting plate, a number of positioning cones are integrally formed on the mounting plate, the back of the seat is provided with a positioning groove area, and a number of positioning grooves matching the positioning cone are set in the positioning groove area, which is used to solve the problem that when the subject's soles touch the ground during the sitting lumbar back muscle strength test, In the process of exerting force, most of the force is generated by stepping on the ground. At the same time, when the subject repeatedly moves his body to squeeze the muscle strength tester, the midpoint of the connecting line between the upper corners of the shoulder blades on both sides will deviate from the position of the muscle strength tester, which will affect the test results.

一种腰背肌力量检测装置
本技术属于医疗器械
,具体涉及一种腰背肌力量检测装置。
技术介绍
量素质是指肌肉在工作时克服内外阻力所表现出来的力量大小和耐力水平。腰背肌作为维持人体上身直立和活动的主要肌肉,是构成人体核心肌群的重要组成部分,在保持腰椎动态平衡,支持和保护脊柱方面起着重要作用。研究表明,腰背肌力量不足与慢性腰背痛的发生有关,在对腰背疼痛的受试者进行治疗时,需要先测量受试者的腰背部肌肉力量。当前临床对于腰背部肌肉力量测试姿势的选择主要有站立位、俯卧位和坐位。目前坐位测试主要通过等速力量测试系统测评腰背肌力量,但其操作复杂,价格昂贵,仅适用于科学研究,不利于大范围开展测试。而传统腰背肌力量坐位测量时,将肌力测试仪固定于座椅上,受试者坐位情况下,肌力测试仪的测量力垫中心与受试者两侧肩胛上角连线的中点相抵,通过受试者后伸发力完成腰背肌力量测试,由于受试者脚掌着地,在发力过程中大部分力由脚部蹬地产生,同时受试者反复移动身体挤压肌力测试仪时,两侧肩胛上角连线的中点会与肌力测试仪的位置出现偏差,影响测试结果。 ...
