RESUMEN
Objective:To explore the clinical efficacy of Kinesio taping combined with extracorporeal shock wave and the plantar pressure evaluation in the treatment of plantar fasciitis. Method:A total of 67 patients with unilateral plantar fasciitis were randomly divided into the control group(ESWT group)and the experimental group(KT combined group).The patients in the two groups were given the same health education and extracorporeal shock wave treatment(ESWT),and the experimental group was treated with Kinesio taping(KT).The pain and functional activity were evaluated by pain visual analogue scale and AOFAS ankle and hind-foot function scale;The insole plantar pressure measuring system was used to mea-sure the peak pressure values of each plantar regions.The clinical efficacy and plantar pressure of the affected side were compared before treatment,the 3rd week of treatment and 5th week of treatment. Result:There was no significant difference in various indcators of the measurements between the two groups before treatment(P＞0.05).The score of pain rating,functional activity scale score and plantar pressure of pa-tients in both groups were significantly improved at the 3rd week and the 5th week of treatment(P＜0.05),com-pared with those before treatment.At the 3rd week of treatment,there was no significant difference between the two groups in pain degree and functional activity scale score(P＞0.05),but there was statistical difference in plantar pressure analysis(P＜0.05).The peak force weight ratio of the medial heel in the KT combined group was significantly greater than that in the control group.At the 5th week of treatment,there were statisti-cally significant differences between the two groups in the score of pain rating,functional activity scale score and plantar pressure(P＜0.05).The KT combined treatment group was significantly better than the control group in the pain improvement and functional activity,and the weight bearing of the middle foot and hind foot was also significantly higher than the control group. Conclusion:Compared with the simple extracorporeal shock wave therapy,the combination of KT therapy can better relieve pain,improve the function of hind foot,correct abnormal foot weight bearing,and improve the gait of patients.
RESUMEN
BACKGROUND:Kinesio taping is often used for the treatment of various sports injuries.The methods of foot and ankle sports taping are complex and diverse.Among them,Fascia taping is applicable to a wider range of people and can be used for different foot posture types,but it still lacks of practical verification,and its specific biomechanical role is not clear. OBJECTIVE:To observe the changes in plantar pressure characteristics of subjects with different foot positions during walking and jogging after Fascia taping. METHODS:Thirty-seven young healthy subjects were recruited from the Yantai campus of Binzhou Medical University to conduct the test.They were scored according to the foot posture index-six items version,and were divided into the supination foot group,the neutral foot group,and the pronation foot group.The static foot morphological indexes(including navicular drop,arch height index,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch)and the pressure-time integral of each foot zone during walking and jogging were collected and calculated respectively before and after Kinesio taping.The specific biomechanical mechanism of Fascia taping was analyzed. RESULTS AND CONCLUSION:(1)General data:There was no statistical difference among the three groups of subjects in general data,such as gender,height,and body mass index(P>0.05).Before taping,there was a significant difference in the foot morphological indexes and the areas of the outer front foot,midfoot,and hindfoot between different foot posture groups(P<0.01).(2)Static foot morphological indexes:After taping,there was no statistically significant difference between the groups in navicular drop,arch height flexibility-longitudinal arch,and arch height flexibility-transverse arch(P>0.05),while there was still a significant difference between the groups in the arch height index(P<0.05).In the supination foot group,the arch height index increased slightly,but there was no significant difference before and after taping(P>0.05).In the pronation foot group,the navicular drop and arch height flexibility-longitudinal arch was significantly reduced,and the arch height index was increased.There was a significant difference before and after taping(P<0.05).(3)The index of plantar pressure during walking:After taping,there was no significant difference between the three groups in the area of lateral forefoot and medial midfoot(P>0.05).In the pronation foot group,the lateral load of the forefoot increased after taping(P<0.05).In the supination position group,the load of the lateral forefoot and midfoot regions increased significantly(P<0.05),while the difference in the rear foot region was not significant(P>0.05).(4)The index of plantar pressure during jogging:After taping,there was no statistically significant difference between groups in the lateral forefoot(P>0.05).In the pronation foot group,the load of the medial forefoot increased significantly(P<0.05).In the supination position group,the load of the lateral forefoot,the middle foot and the rear foot region increased significantly(P<0.05).(5)The results showed that the Fascia taping was suitable for different foot postures.It could not only correct the static foot structure of subjects with different foot postures,but also regulate the abnormal plantar pressure distribution during the dynamic activities of walking and jogging,and the load of the midfoot,forefoot,and hindfoot in the supination and pronation posture tended to normal foot posture load level.
RESUMEN
BACKGROUND:During stair walking,different muscles work in concert and compensate for each other,and it is unclear whether weakened muscle strength actually affects stair fall risk in older adults.Real-time electromyographic signals from older adults during stair walking are used to reflect high fall risk in older adults during stair walking,which may further improve the accuracy of prediction methods. OBJECTIVE:To investigate the effects of aging on lower limb muscle activation in older adults during stair walking and to analyze the relationship between their muscle activation characteristics and stair fall risk. METHODS:Subjects were divided by age into an older group(n=19)and a younger group(n=18)group and were asked to walk on a 10-step staircase at a natural speed,incorporating surface electromyography acquisition technology,to capture surface electromyography signals during stair walking and calculate the root mean square(RMS)to analyze differences in muscle activation levels.Logistic regression analysis was utilized to establish a predictive model for stair fall risk in older adults by incorporating the lateral femoral and gastrocnemius muscle RMS.The discrimination of the model was evaluated by the receiver operating characteristic curve and area under the curve,and the fit of the model was evaluated using the Hosmer-Lemeshow test RESULTS AND CONCLUSION:Activation of the rectus femoris(Z=-3.464,P=0.001;t=3.379,P=0.002)and lateral gastrocnemius muscle(Z=-2.978,P=0.003;Z=-3.555,P<0.001)was higher in older adults than in younger adults when walking up and down stairs.Activation of the anterior tibialis(Z=-2.350,P=0.019)and medial(Z=2.321,P=0.020)and lateral(t=3.158,P=0.004)gastrocnemius muscles was higher in older adults when ascending stairs than descending stairs.Older adults at risk for falls had less activation of the lateral femoral muscle(Z=-2.613,P=0.009),medial gastrocnemius muscle(Z=-2.286,P=0.022)when walking upstairs,and lateral femoral muscle(Z=-2.368,P=0.018)when walking downstairs than did older adults not at risk for falls.The predictive ability,goodness of fit,and discrimination of the stair fall prediction model for older adults based on surface electromyography were good(P-value of 0.010 for the Omnibus test of the model coefficients,P-value of 0.214 for the Hosmer-Lemeshow test,and the area of the curve of the upper staircase lateral femoral muscle=0.856,P=0.009).(5)The model was modeled with a cut-off value of 38.64 for the upper staircase lateral femoral muscle RMS value and there was a 0.952-fold increase in the risk of staircase falls for each unit decrease in the upper staircase lateral femoral muscle RMS in older adults.
RESUMEN
Objective:To analyze the clinical and epidemiological features of human rhinovirus (HRV) infection in adult patients with upper respiratory tract infection (URTI) in Nanjing.Methods:Epidemiological data of adult patients with URTI in Nanjing from October 2021 to September 2022 were collected. Clinical specimens were collected and subjected to quantitative reverse transcription polymerase chain reaction (qRT-PCR) for the detection of 14 common respiratory viruses. The VP4/VP2 genes in HRV-positive samples were amplified and sequenced. Then a phylogenetic tree was constructed.Results:A total of 399 pharyngeal swabs were collected from patients with URTI. The overall positive rate of respiratory viruses was 28.07% (112/399) with HRV accounting for most at 9.52% (38/399). Thirty-seven VP4/VP2 sequences were successfully obtained from the 38 HRV-positive specimens. Three genotypes involving 25 serotypes were identified with 13 strains belonging to HRV-A, 14 belonging to HRV-B, and 10 belonging to HRV-C. The three genotypes of HRV showed alternate prevalence or co-prevalence.Conclusions:HRV was the main pathogen causing URTI in adult patients in Nanjing from October 2021 to September 2022, and three genotypes of HRV-A, B and C were prevalent alternatively or together.
RESUMEN
ObjectiveTo explore the effect of core stability training on dynamic balance and surface electromyography (sEMG) after anterior cruciate ligament reconstruction (ACLR), and to analyze the correlation between balance index and sEMG. MethodsFrom March to December, 2022, 32 patients with ACLR in Yantai Affiliated Hospital of Binzhou Medical University were randomly divided into control group (n = 16) and experimental group (n = 16). The control group accepted routine rehabilitation treatment, and the experimental group added core stability training, for six weeks. They were evaluated with American Hospital for Special Surgery Knee Score (HSS) and International Knee Documentation Committee Knee Score (IKDC), and the dynamic balance function and sEMG were measured before and after treatment, and the correlation between dynamic balance index and root mean square (RMS) of sEMG was analyzed. ResultsAfter treatment, the scores of HSS and IKDC increased significantly in both groups (|Z| > 3.526, |t| > 63.544, P < 0.001), and were better in the experimental group than in the control group (Z = -2.392, t = 2.650, P < 0.05); the length of gait line and single support line increased significantly, the medial-lateral displacement displacement decreased (|t| > 2.368, Z = -3.516, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.497, Z = -3.091, P < 0.05); the RMS of gluteus maximus and gluteus medius increased in the experimental group (t = -5.900, Z = -2.741, P < 0.01), and were better than those in the control group (t = 3.930, Z = -3.260, P < 0.01). After treatment, the RMS of gluteus maximus and gluteus medius in both groups were positively correlated with gait line length and single support line length, and were negatively correlated with medial-lateral displacement (|r| > 0.502, P < 0.01). ConclusionCore stability training could significantly improve knee joint function and dynamic balance, and enhance the activation of gluteus maximus and gluteus medius. Dynamic balance is highly correlated with sEMG.
RESUMEN
Background Gene encoding optineurin (OPTN) is a causative gene for glaucoma and amyotrophic lateral sclerosis,with a more expression in retina.Our previous study isolated OPTN-interacting proteins and identified that the gene encode the basic leucine zipper (bZIP) transcription factor neural retina leucine (NRL) zipper,a causative gene for retinitis pigmentosa,and further study demonstrated the interaction between OPTN and NRL proteins in nuclei of cultured HeLaS3 cells.Objective This study was to determine the protein binding site of OPTN necessary for NRL binding.Methods A deletion series of OPTN-expression plasmids were constructed and co-expressed with hemagglutinin (HA)-tagged NRL in HeLaS3 cells,respectively.The cytoplasmic and nuclear fractions were used to perform co-immunoprecipitate (CoIP) and Western blot with anti-tag antibodies.Results In the nuclear fractions of cells transfected with the del1 st,del2nd or del3rd plasmid,a band of coimmunoprecipitated HA-labelled NRL (HA-NRL) was detected.However,the del4th plasmid did not produce a band.The NRL band was not found in cytoplasmic fractions from transfected cells with any of the deletion plasmids or with the whole-length OPTN plasmid.Conclusions The protein binding site of OPTN necessary for NRL binding is determined.This result demonstrates the binding of Flag-OPTN and HA-NRL in HeLaS3 cells.A series of partial-deletion OPTN plasmids demonstrated that the tail region (423-577 amino acids) of OPTN was necessary for binding with NRL.
