Research On Pressure Distribution And Correction Effect Of Orthosis Belt

Long term desk work will lead to abnormal load-bearing of the spine,unbalanced pressure in the intervertebral disc,and then hyperosteogeny or rupture of the fibrous ring of the intervertebral disc.At the same time,the related muscles are in an uncoordinated stress state for a long time,which is easy to cause muscle and ligament strain,and the change of muscle strength will reverse affect the bone bending,making it difficult to recover the bad posture.Keeping the ideal standing and sitting posture can maintain a balanced pressure on the spine and avoid unnecessary injury.The posture correction products on the market can help the human body maintain good posture and correct bad posture.In order to explore the correction effect and authenticity,this paper selects four posture correction belts to evaluate the effect of each style through body surface angle measurement.（1）According to the market researc.h,choose four types of straightening belts,and analyze the style,size and detailsThrough literature review,comb the normal and abnormal conditions of spine structure and its bending shape,comb the formation mechanism of bad posture and related muscles,clarify the interaction between skeletal muscles and their impact on posture,and make it clear that posture correction products arc only used for muscular posture problems without bone deformation.Through the investigation of medical braces,the design principle and action principle of posture correction products are summarized.Through the market research and patent research of straightening products,the straightening belt is selected as the research object.By extracting the winding mode of straightening belt,four structural features are summarized.Ac.cording to the style,the style drawing and structure drawing of purchased products are drawn,and the style,size and details are analyzed.（2）According to the causes and judgment methods of posture problems,judge the posture problems of the subjects,compare the posture differences before and after wearing different styles through body surface angle measurement,and evaluate the effect of posture correction beltAccording to the size of the purchased posture correction belt,select subjects with appropriate body shape,and judge the existing posture problems one by one,including kyphosis,round shoulder,scoliosis,high and low shoulder and neck exploration.The initial state,ideal state and wearing state of standing and sitting posture were characterized by measuring the body surface angle and cervical spine point,and the differences before and after wearing the posture correction belt were compared.Through the posture change of standing posture,the improvement of posture problems by the posture correction belt is analyzed.Through the posture change of sitting posture,the ability of the posture correction belt to help the wearer maintain a good sitting posture is analyzed.Calculate the angle change and explain the overall significance of angle positive and negative,size and change to human body shape.Through the difference mean test,judge whether each angle has a significant effect,analyze the influence of different styles on the angle change,sort each style of posture correction belt according to the effect,and then analyze the relationship between the structural design of posture correction belt and correction effect.By drawing the posture chain Abstract back curve,the posture change is analyzed as a whole,and the interaction between body surface angles is explored through correlation analysis.The results show that the partial posture correction belt has a significant effect on the neck,chest,back,shoulder and waist.Based on the overall analysis,the posture correction belt is limited by the style and has no direct effect on the waist,but the change of thoracic segment will affect the increase of lumbar forward tilt,which is not easy to detect,but is harmful to the health of spine.（3）Test the pressure distribution of each posture correction belt,and analyze the relationship between pressure and correction effect and wearing comfortTest the pressure distribution of the posture correction belt,evaluate the subjective pressure and comfort of each style,draw the objective pressure gradient distribution diagram,analyze the correlation between the objective pressure and the subjective pressure,and analyze the relationship between the pressure of the posture correction belt and the correction effect.Combined with the comfort pressure range of various parts of human body,the relationship between the pressure of posture correction belt and comfort is analyzed.
