| Plantar fasciitis,also known as plantar fasciitis,plantar fasciitis,etc.,is one of the most common plantar diseases and is the main cause of plantar heel pain.Sacral fasciitis mainly depends on conservative treatment,including manual treatment and functional exercise,orthopedic braces,extracorporeal shock waves,oral drugs,local injections,and so on.Foot orthosis is an important treatlent method for plantar fasciitis.It is usually used to help patients with plantar fascia to correct the poor line of force in the ankle,support the arch of the foot,balance stress,and relieve symptoms.Orthopedic insoles,as important members of orthopedic appliances,are divided into prefabricated and customized types.Most of the orthopedic insoles on the market are prefabricated orthopedic insoles.It is difficult to correct abnormal foot force lines and abnormal foot pressure distributions based on individual patient differences.The main purpose of this study is to analyze and evaluate the abnormalities of plantar pressure and gait in patients with plantar fasciitis through the Italian Diasu plantar pressure analysis system.The improvement of plantar pressure and gait in patients with plantar fasciitis will be evaluated,and the effect of custom-made orthopedic insoles on the treatment of plantar fasciitis will be evaluated.Research subjects:30 patients with lateral sacral fasciitis and 30 normal subjects.Divided into two groups,namely the normal subject group and the PF patient group,there was no significant difference between the two groups of subjects in baseline data such as gender,age,height,weight,BMI index.Observation and evaluation indicators:VAS pain score,AOFAS score,distance COG-COP X,distance COG-COP Y,maximum pressure,average pressure,foot surface pressure ratio,forefoot load,midfoot load,hindfoot load,foot angle,LPA,TPA,step width,step length,step length,step length,average step time,rate,acceleration,deceleration,standing time,standing DS time,swing time,load change,hind/forefoot load change,resultant force COF.Statistical methods:Use SPSS 23.0 software to perform statistical analysis on all data.The measurement data conforms to the normal distribution and is expressed as mean:L standard deviation;the measurement data does not conform to the normal distribution and is expressed by the median(interquartile range);Composition ratio representation;comparison of measurement data between two groups that meet the normal distribution adopts two independent sample t tests;comparison of measurement data that does not meet the normal distribution adopts the non-parametric Mann-Whitney U test;Paired design measurement data comparison,the difference is in accordance with the normal distribution using paired t test;the difference is not in accordance with the normal distribution using non-parametric Willcoxon rank sum test(/Sign test);counting data using chi-square test;VAS score,AOFAS score treatment The trend of change with time before and after was analyzed by repeated measures analysis of variance.If P<0.05,then LSD-t method is used to compare each other;P<0.05 means that the difference is statistically significant.Results:Patients with plantar fasciitis had mild pain and obvious ankle dysfunction before treatment.When a normal person stands static,the center point of the plantar pressure is generally located at the lower right of the geometric center of the foot print area,and the two points are very close.In patients with plantar fasciitis,the pressure center moves to the healthy side in the X direction,indicating that the healthy side has more stress on the plantar floor than the affected side,while in the Y direction,the pressure center moves forward and the force on the forefoot increases.In patients with plantar fasciitis,the maximum pressure value of the affected foot is significantly higher than that of normal subjects,while the average pressure increase is not obvious.In patients with plantar fasciitis,the pressure on the feet is not even,and the force on the affected foot is significantly reduced.And in the front and middle.For hindfoot load,patients with plantar fasciitis had significantly increased forefoot load compared with normal subjects,while midfoot and hindfoot load decreased significantly.Patients with plantar fasciitis had significantly smaller foot angles than normal subjects,while LPA and TPA sizes were not significantly different from normal subjects.The step width and interstage length of patients with plantar fasciitis were not significantly different from those of normal subjects,while the step length and step length were significantly shorter than normal subjects.The average time,speed,acceleration,deceleration,and standing time of the feet of patients with plantar fasciitis were significantly lower than those of normal subjects,but there was no significant change in the DS time and swing time of the standing position.In patients with plantar fasciitis,the load change of the affected foot is significantly higher than that of the normal subjects,and the load change of the hind foot/forefoot is significantly reduced,while there is no significant change in the combined force COF.Through orthopedic insole treatment,the VAS score was significantly reduced,and the AOFAS score was significantly increased.The distance COG-COP.X increased significantly,the distance COG-COP.Y decreased significantly,and the absolute value of both decreased significantly.In patients with plantar fasciitis,there was no significant change in the maximum pressure,average pressure,and midfoot load of the foot,and the pressure surface ratio of the foot increased significantly.In addition,the forefoot load decreased significantly and the hindfoot load increased significantly.After treatment with orthopedic insoles,the foot angle increased,but the degree of increase was not statistically significant.There was no significant change in LPA and TPA.After treatment,the patient's step length increased significantly,and the step width,step length,and interstage length did not change significantly.The average time and speed of the patient's pace increased significantly,and the standing time increased significantly compared to before,while the acceleration,deceleration,standing DS time,and swing time did not change significantly.The COF of the resultant force increased significantly,but there was no significant difference in the load change and the load change of the hind foot/forefoot.Research conclusions:Patients w:ith plantar fasciitis have increased stress on the plantar side of the healthy side and the forefoot of the affected side during static standing.During the walking process,the center of gravity of the affected foot moves forward,hindfoot eversion,forefoot intermal rotation,reduced step efficiency,and decreased foot stability.Wearing orthopedic insoles can help reduce pain in patients with plantar fasciitis,improve their ankle function,correct abnormal pressure distribution on the soles of the feet,improve step efficiency,improve foot stability,and make the foot's flipping action more complete.There was no significant improvement in the changes in the load of the biped and the hind foot/forefoot,and the correction of the abnormal foot angle was not obvious. |
