Design And Clinical Effect Observation Of A Functional Exercise Device For Low Back Muscles Combined With Sensing Technology

Objective: In this study,by designing a device to assist patients in lifting lower limbs and reducing waist load,we can complete "flying swallow" functional exercise of low back muscle,so as to help patients improve the symptoms and prognosis of low back pain.The effect of the instrument on the recovery of lumbar function was studied.Methods: On the basis of pneumatic power and pressure sensing technology,the equipment for reducing waist load and the monitoring and control system for monitoring whether patients exercise independently and regulate automatically are developed,and the device design is completed.After that,30 patients with degree I degenerative spondylolisthesis who received voluntary treatment in the first affiliated Hospital of Hunan University of traditional Chinese Medicine from January 2020 to February 2021 were randomly divided into two groups.The control group was treated with flying swallow exercise independently,and the treatment group was treated with instrument-assisted flying swallow functional exercise for 4weeks.The VAS and ODI scores were observed,and the curative effect and the height of leg lifting were observed.Results: Based on pneumatic power and pressure sensing technology,the design and manufacture of low back muscle functional exercise equipment are completed.The device has the advantages of individuation,portability,and can monitor whether the patient exerts himself or not.After the treatment of low back muscle functional exercise equipment,in the 30 cases studied,the lumbar pain score(VAS score)and lumbar function score(ODI score)were improved,the height of leg lifting was improved,and the therapeutic effect of the treatment group was better than that of the control group.Conclusion: In this study,by designing a device to assist patients to lift the lower limbs and reduce the waist load,we can complete the flying swallo functional exercise of low back muscle functional exercise equipment,so as to help patients improve the symptoms and prognosis of low back pain.The traditional exercise methods in orthopedics and trauma science of traditional Chinese medicine were studied with modern science and technology,and a new type of functional exercise equipment of low back muscle was made.The brace helps patients to restore a healthy life early by assisting patients with functional exercise and monitoring whether patients exert their own strength.It is an effective low back muscle functional exercise device.And in the observation of its clinical effect,it is concluded that the instrument has a good effect on the patients with first-degree degenerative spondylolisthesis.
