| Objective:1.Observe the characteristics of heel temperature changes in patients with chronic plantar fasciitis and discuss the clinical evaluation value of ultrasound and infrared thermal imaging for the pain and function of patients with chronic plantar fasciitis.2.To study the injection of steroid hormones in patients with chronic plantar fasciitis Short-term efficacy.To explore the value of ultrasound and infrared thermal imaging for the clinical efficacy of hormone therapy in patients with chronic plantar fasciitis.Methods:1.A total of 58 patients with clinical diagnosis of unilateral chronic plantar fasciitis were selected,and they were divided into symptomatic and asymptomatic sides according to whether they were symptomatic.The patient's symptomatic proximal plantar fascia thickness was recorded.Divide the heel skin into 5 regions of interest according to the quadrant.Use SP-9000 medical thermal imaging camera to observe the patient's bilateral soles on the same day and the next day and record the average temperature of each region of interest in the heel.Use Visual analogue scale(VAS)and Foot and Ankle Disability Index Items(FADI)were used to evaluate patients' pain and function.2.A total of 26 patients with final clinical diagnosis of unilateral chronic plantar fasciitis were included and randomly divided into a test group(group A)and a control group(group B),with 13 cases in each group.Under ultrasound guidance,group A was injected with a mixture of Diprospan 1ml + 2% lidocaine hydrochloride injection 1ml into the plantar fascia surface,and group B was injected with physiological saline 1ml + 2%lidocaine hydrochloride onto the plantar fascia surface 1ml of mixed solution for injection.Ultrasound was used to measure the thickness of the plantar fascia before treatment(T0)and 1 month after treatment(T1)and to observe whether the plantar fascia complicated complications such as bleeding,infection and rupture after treatment;infrared thermal imaging to measure T0 The temperature of each region of interest in the heel part at t1 and t1(t: t1,t2,t3,t4,t5)and the midpoint temperature tr of the forehead,define the difference between the temperature of the forehead and each region of interest in the heel?t:?t1,?t2,?t3,?t4,?t5;VAS and FADI were used to evaluate the pain and dysfunction of patients at T0 and T1.Results:1.The results of paired t-test showed that there were statistical differences in the temperature of the 5 areas of interest between the symptom side and the asymptomatic side(P <0.05).The temperature of the 5 regions of interest collected by the two infrared thermal imagings was tested for correlation coefficient within the group.The results suggest that the ICC results suggest that the infrared thermal imaging has a highintra-group consistency and good repeatability for the 5 regions of interest(ICC : 0.763?0.858).The results of Spearman rank correlation test showed that there was no correlation between the average temperature of each area of ??interest in the symptomatic foot plant and the VAS score(P> 0.05),and the average temperature of 5 areas of interest in the heel of the symptomatic side were all There was a correlation between the FADI scores(P <0.05),and the average temperature of the five interested areas in the symptomatic heel was correlated with the pain scores in the FADI(P <0.05).The results of Spearman rank correlation test showed that there was no correlation between the thickness of symptomatic plantar fascia and VAS score(P> 0.05),and there was no correlation between the thickness of symptomatic plantar fascia and FADI score(P>0.05).2.Chi-square test was used to compare the sex ratio of the two groups of subjects,and independent sample-t test was used to compare the age and course of the two groups of subjects.The results suggest that the two groups of subjects were not statistically different in gender,age and course of disease.The results of paired t test indicate that the thickness of plantar fascia in group A at T1 is not statistically different from the thickness of plantar fascia at T0(P> 0.05).There was no statistical difference in the thickness of the bottom fascia(P> 0.05).The results of Mann-Whitney U test showed that there was a statistical difference between the VAS score,FADI score,delta t of each interest area in heel A at T1 and the VAS score,FADI score,?t of each interest area in heel at T0(P <0.05),There is no statistical difference between the VAS score,FADI score,?t of each interest area of the heel at T1 and the VAS score,FADI score,?t of each interest area of the heel at T1(P>0.05).No side effects such as rupture or rupture occurred after treatment in both group A and Group B.Spearman rank is used.Relevant results suggest that infrared thermography shows that there is no correlation between the relative change of ?t(?t)and the change of VAS scores in each area of the plantar before and after treatment in group A(P> 0.05).There was a correlation between ?t in each area of interest and the change in FADI score(P <0.05),and there was a correlation between the ?t in each area of interest in the sole of the foot before and after treatment and the change in the pain score phase in FADI(P<0.05).Conclusions:1.Patients with plantar fasciitis have symptomatic lateral heel skin temperature increase,and there is a correlation between heel temperature and clinical score.The heel temperature detected by infrared thermal imaging can be used to evaluate chronic plantar fasciitis Objective indicators of patients' pain and function,and provide more reference value for studying the pathogenesis of diseases.The thickness of the plantar fascia in patients with chronic plantar fasciitis is not related to the patient's pain and functional score.Although the thickness of the plantar fascia displayed by ultrasound can be used as a diagnostic basis for plantar fasciitis,it cannot be used as an evaluation.Index of pain and function of chronic plantar fasciitis.2.Local injection of hormones can significantly improve the pain and dysfunction of patients with chronic plantar fasciitis.When using hormones to treat patients with chronicplantar fasciitis,ultrasound cannot be used as a hormone to treat patients with chronic plantar fasciitis Evaluation indicators,but can be used as an auxiliary method to evaluate the safety of treatment.Infrared thermography can be used as an evaluation index for the clinical efficacy of hormone therapy for chronic plantar fasciitis. |
