Measuring instrument for accurately measuring dorsal extension and plantar flexion muscle force of hallux

Abstract

The invention discloses a measuring instrument for accurately measuring dorsal extension and plantar flexor muscle force of the hallux. The measuring instrument comprises a main body, a base and a rear baffle, wherein two adjustable hallux limiting adhesive tapes are arranged at one side, far away from the rear baffle, of the top of the base; first pressure sensors are mounted in the tops of the hallux limiting adhesive tapes; two adjustable second pressure sensors are arranged on the base; display screens used for displaying pressure values of the first pressure sensors and the second pressure sensors are mounted at the sides, far away from the rear baffle, of the second pressure sensors; and an adjustable wide adhesive tape is arranged in the middle of the base. The measuring instrument is simple to operate and convenient to use, enables the dorsal extension and plantar flexion muscle force of the hallux to be objectively quantified, is beneficial for medical staff and patients to obtain accurate muscle force measurement values, can be widely used for evaluating the preoperative hallux flexion and extension muscle force conditions and postoperative muscle force changes of the patients, provides important reference basis for formulating clinical diagnosis and treatment schemes, and can timely reflect postoperative neurological function recovery conditions to increase the confidence of patients in recovery.

Description

technical field [0001] The invention belongs to the technical field of muscle strength measurement, and in particular relates to a measuring instrument for accurately measuring hallux dorsiflexion and plantarflexion muscle strength. Background technique [0002] Lumbar degenerative disease is a common and frequently-occurring disease, including lumbar disc herniation, spondylolisthesis, lumbar spinal stenosis, etc., often accompanied by different degrees of nerve root compression, among which L5 and S1 nerve roots are affected Pressure is most common. Damage to the L5 nerve root is mainly manifested as hypoesthesia on the anterolateral side of the calf and dorsum of the foot, and decreased strength of the hallux dorsiflexor muscle; damage to the S1 nerve root is manifested as hypoesthesia on the lateral side of the foot, and decreased strength of the hallux plantarflexor muscle. For those patients whose symptoms did not improve after strict conservative treatment, and the m...

Problems solved by technology

This method is simple and easy to operate, without the aid of equipment, and can evaluate the patient's muscle strength anytime and anywhere. However, this method of muscle strength measurement is mainly based on the subjective feeling of the doctor's hands, and the measurement accuracy is not good. Poor reproducibility and lack of consistency in assessment results between different doctors
