ABSTRACT

PURPOSE: Steroid-related osteonecrosis of the femoral head (ONFH), arising from steroid administration for underlying diseases, represents a unique pathology for total hip arthroplasty (THA) and typically affects a younger demographic compared to osteoarthritis (OA). Given the significant age-related differences, this study aims to employ propensity score matching to align patient backgrounds between these two diseases and compare physical function. Additionally, our objective is to scrutinize the patterns of clinical score recovery over the course of one year following THA. METHODS: Using propensity score matching, 29 patients each with steroid-related ONFH and OA were selected. Muscle strength (hip abductor and knee extensor) were assessed before and after THA. Additionally, recovery of the Harris Hip Score (HHS) and Oxford Hip Score (OHS) up to one year postoperatively was analyzed. RESULTS: The steroid-related ONFH group exhibited gender bias and significantly younger age compared to the OA group. Propensity score matching achieved balanced patient backgrounds. Physical function showed trends of lower hip abduction and knee extensor strength on the operative side in the steroid-related ONFH group. Notably, nonoperative knee extensor strength decreased significantly after matching. HHS and OHS were poor in steroid-related ONFH up to three months postoperatively but recovered after six months. CONCLUSIONS: Patients with steroid-related ONFH experience positive outcomes in clinical score following THA. Propensity score matching effectively identified muscle weakness on both operative and nonoperative sides, highlighting its utility in comparative analyses.

ABSTRACT

OBJECTIVE: This study aimed to investigate the association between muscle density as an indicator of fatty infiltration of lower extremity muscles and physical activity (PA) after total hip arthroplasty (THA) and identify the patient characteristics with high postoperative PA. METHODS: This study included 62 female patients who underwent THA for unilateral hip osteoarthritis. Muscle density of the gluteus maximus, gluteus medius, iliopsoas, and quadriceps muscles was measured using computed tomography (CT). PA was assessed using University of California, Los Angeles (UCLA) activity scores. CT and UCLA activity score were obtained before and 1 year after THA. The patients were divided into two groups, sufficient (score ≥ 6) and insufficient (score < 6) activity groups, based on their level of PA as determined by their UCLA activity score 1 year after THA. The association of PA with the amount of changes in muscle density was examined with Spearman's rank correlation coefficient. Logistic regression analysis was performed to identify postoperative factors determining PA at 1 year after THA. RESULTS: Spearman's rank correlation coefficient showed a significantly positive association between recovery in PA and an increase in muscle density of the gluteus maximus, gluteus medius, iliopsoas, and quadriceps muscles. Additionally, logistic regression analysis confirmed that postoperative muscle densities of the gluteus maximus and quadriceps muscles were variables determining the PA 1 year after THA. CONCLUSION: The findings of this study indicated that the improvement of fatty infiltration in lower limb muscles, especially in the gluteus maximus and quadriceps, is likely to promote the increase in postoperative PA.

ABSTRACT

BACKGROUND & AIMS: Nutritional assessment in allogeneic hematopoietic stem cell transplantation (allo-HSCT) is important and decreased skeletal muscle mass is a risk factor for the development of infection. Recently, it has become clear that qualitative rather than skeletal muscle mass loss is a marker that reflects post-transplant outcome, but its association with the development of infection remains unclear. Therefore, we assessed skeletal muscle status by body composition using bioelectrical impedance analysis (BIA) and investigated its association with the development of infection. METHODS: A retrospective cohort study was conducted to assess the quantity as well as quality of skeletal muscle using the body composition of BIA assessment. The quantitative (appendicular skeletal muscle mass index; ASM) and qualitative (phase angle; PhA) indicators of skeletal muscle calculated from body composition analysis were used to determine factors influencing the development of infection after allo-HSCT. RESULTS: In total, 80 adult patients, aged 20-70 years (median, 52) were included in this study. The ASM was mildly decreased after allo-HSCT and PhA was significantly decreased. Furthermore, low pre-transplant PhA was identified as an independent risk factor for the development of infection early after transplantation, with a cutoff value of 4.9°. CONCLUSION: In particular, pre-transplant PhA may predict the development of infection early after allo-HSCT, and muscle indices that can be assessed with pre-transplant body composition are a useful evaluation method that can discriminate post-transplant outcomes.

ABSTRACT

PURPOSE: The 6-min walk test (6MWT) of allogenic hematopoietic stem cell transplantation (allo-HSCT) recipients has been gaining attention; however, minimal differences have not been reported. This study aimed to determine the minimal important difference (MID) in the 6MWT among hospitalized patients with allo-HSCT. MATERIALS AND METHODS: The MID of the 6MWT was calculated using three different methodologies based on an anchor-based method; basic anchor-based methods, linear regression analysis, and receiver operating characteristic (ROC) curve analysis. The decrease in the score of Question 2 of the European Organization for Research and Treatment of Cancer Quality of life questionnaire core-30 was included as an anchor question for calculating the MID. Both actual and percentage changes in 6MWT values from baseline and at discharge were used in the MID calculations. In the actual and percentage change of the 6MWT, the one with the larger the area under the curve in the ROC curve was recommended as the MID. RESULTS: Among the three methods using actual values, the largest MID of the 6MWT was -37.5 m (sensitivity: 54%, specificity: 88%). CONCLUSION: More careful follow-up after discharge is necessary for allo-HSCT patients who show a reduction of 37.5 m or more in the acute illness phase.


Advancements in allogeneic hematopoietic stem cell transplantation have improved the survival rates of individuals with malignant hematological disorders, and efforts should now be focused on enhancing their physical function and quality of life.There is a problem that the physical performance of the patients is reduced by the side effects of treatment.More careful follow-up after discharge is necessary for allo-HSCT patients who show a reduction of 37.5 m or more in the acute illness phase.

ABSTRACT

BACKGROUND: The purpose of this study is to investigate the relationship between gait and fat infiltration in anterior and posterior gluteus minimus in the patients with hip osteoarthritis. METHODS: Ninety-one female patients who were diagnosed as the unilateral hip osteoarthritis, classified into Kellgren-Lawrence global scoring system grades 3 or 4, and candidate for total hip arthroplasty were retrospectively reviewed. The horizontally cross-sectional regions of interest for the gluteus medius and anterior and posterior gluteus minimus were manually circumscribed in a single transaxial computed tomography image and muscle density of those regions were obtained. The gait was assessed as the step and speed with the 10-Meter Walk Test. The multiple regression analysis was used to compare the step and speed with age, height, range of motion in flexion, the muscle density of anterior gluteus minimus in the affected side, and that of gluteus medius muscle in both affected and unaffected sides. FINDINGS: Multiple regression analysis for step revealed that the muscle density of anterior gluteus minimus in the affected side and height were the independent predictors for step (R2 = 0.389, p < 0.001). That for speed identified the muscle density of anterior gluteus minimus in the affected side as the only factor determining speed (R2 = 0.287, p < 0.001). INTERPRETATION: The fatty infiltration of anterior gluteus minimus muscle in affected side can be a predictor for the gait in in female with unilateral hip osteoarthritis and candidates for total hip arthroplasty.

ABSTRACT

OBJECTIVE: To determine the reproducibility, criterion-related validity, and minimal clinically important difference (MCID) of the stair negotiation test (SNT) after total hip arthroplasty (THA). METHODS: Sixty patients who underwent THA were included in this study. They performed the SNT and rated their difficulty in stair negotiation (question 7 of the Oxford Hip Score [OHSQ7]) before and 6 months after surgery. The SNT determined the time taken by a patient to ascend, turn around, and descend the stairs (15 cm × 4 steps) and was measured twice each time. As a measure of reproducibility, the intraclass correlation coefficient (ICC1,1) was calculated using the preoperative SNT. As an index of criterion-related validity, Spearman's rank correlation coefficient was used to evaluate the relationship between the better score of two trials in the preoperative SNT and the OHSQ7. The MCID of the SNT was calculated using the distribution-based method and the anchor-based method. The change in the OHSQ7 between before and after surgery was used as an anchor in the latter method. RESULTS: The ICC1,1 of the SNT was 0.97. The SNT was significantly correlated with the OHSQ7 (r = 0.40, p < .05). Moreover, the anchor-based MCID of the SNT was 1.98 seconds. CONCLUSION: The SNT is an objective assessable test of stair negotiation ability in post-THA patients that has good reproducibility and moderate criterion-related validity. Changes in the SNT beyond the MCID (1.98 seconds) represent clinically important changes in stair negotiation ability.

ABSTRACT

A decline in physical functions at the early stage of allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a serious issue. Belt electrode-skeletal muscle electrical stimulation (B-SES) can induce significant muscle contractions with electrical stimulation and reduce muscle weakness. However, this approach has not been used in allo-HSCT patients. This study aimed to examine the effect of B-SES on physical function, and safety in patients during the early post-transplantation period. Forty-three adult patients who underwent B-SES after allo-HSCT were stratified into 2 groups based on the intensity of electrical stimulation (high versus low). B-SES was performed in combination with exercise therapy for 4 post-transplantation weeks. Knee extensor strength (KES) in the low B-SES group decreased significantly, whereas no change was observed in the high-intervention group. A significant positive correlation was observed between total intensity and ΔKES. A reduction in the 6-minute walking distance in the high B-SES group patients was lower than that of historical data. Two patients had B-SES-related complications including muscle pain. This study is the first to propose a new rehabilitation intervention strategy for allo-HSCT. Combined use of B-SES may be a new approach to reducing the decline of physical function in the early post-transplantation period.

ABSTRACT

During clinical courses involving treatment with allogeneic hematopoietic stem cell transplantation (allo-HSCT), multidisciplinary patient assessment including physical function is indispensable, and quantitative skeletal muscle loss is a poor prognostic marker. Deteriorating quality of muscle from intramuscular adipose tissue degeneration can be important as well, because many patients are cachexic or sarcopenic before allo-HSCT, although this approach has not yet been used in such patients. We conducted this retrospective cohort study to evaluate the quality as well as quantity of skeletal muscle using computed tomography (CT) scans. The psoas muscle mass index (PMI) and radiographic density (RD) calculated by cross-sectional area and averaged CT values of the psoas major muscle at the umbilical level were used to determine the quantity and quality of muscle, respectively. A total of 186 adult patients, ranging in age from 17 to 68 years (median, 49 years), were included in this study, with 46 (24.7%) assigned to the lower PMI group and 49 (26.3%) assigned to the lower RD group. Low RD was identified as an independent risk factor for poor overall survival after allo-HSCT (adjusted hazard ratio [HR], 2.54; P < .01), whereas PMI was not significant. Decreased RD along with a reduced 6-min walking distance before transplantation were significant factors in increased nonrelapse mortality (HR, 2.69; P = .01). This study is the first to suggest the use of a qualitative skeletal muscle index to serve as a prognostic indicator following allo-HSCT. RD should be included in pretransplantation screening parameters, and approaches that include rehabilitation focused on improving both muscle quality and quantity may improve the prognosis of allo-HSCT.

ABSTRACT

OBJECTIVE: To develop clinical prediction rule (CPR) of physical activity 1 year after total hip arthroplasty (THA). DESIGN: Retrospective cohort study. SETTING: University hospital with orthopedic surgery. PARTICIPANTS: The study group included 321 patients (56 men) who underwent primary THA (N=321). INTERVENTION: Not applicable. MAIN OUTCOMES MEASURES: The data collected included age, body mass index, clinical score from the questionnaires, hip pain, range of motion, muscle strength, and Physical functions (10-meter walk test [10MWT], timed Up and Go test, sit-to-stand test). Patients were classified into sufficient and insufficient activity groups based on their University of California, Los Angeles (UCLA) activity score 1 year after THA. Variables measured preoperatively and 3 weeks postoperatively were analyzed using univariate and multivariate methods to derive CPR for physical activity. RESULTS: A CPR was developed using the following 5 factors and cutoffs: age 70.5 years or younger, preoperative UCLA activity score ≥3.5, preoperative hip abduction strength ≥0.54 Nm/kg, preoperative knee extension strength ≥1.04 Nm/kg, and 10MWT ≤8.49 seconds 3 weeks after surgery. The presence of 4 of the 5 factors predicted a sufficient physical activity level at 1 year, with a positive likelihood ratio of 5.94 and probability of 85.4%. The presence of 5 predictor variables increased the probability of sufficient physical activity after THA to 94.7%. CONCLUSIONS: This study developed a CPR for physical activity 1 year after THA. Having 4 or more of the 5 measurements were useful indicators for predicting of physical activity 1 year postoperatively.

ABSTRACT

PURPOSE: Decline in physical function in the early stage after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a major challenge. Exercise tolerance tests, such as the 6-min walk test, are useful markers for predicting exercise tolerance and various other traits, including cardiometabolic risk and non-relapse mortality. This retrospective cohort study aimed to investigate and identify predictors of recovery of exercise tolerance in the early stage after allo-HSCT. METHODS: Ninety-eight patients were classified into recovery and non-recovery groups according to the median 6-min walk distance (6MWD) at discharge. RESULTS: Logistic regression analysis revealed that pre-post change in knee extensor strength (ΔKES) and hematopoietic cell transplantation comorbidity index were useful predictors of recovery of exercise tolerance at discharge and moderate predictors of 6MWD recovery in the early post-transplant period. Receiver operating characteristic analysis showed that pre-transplant ΔKES was an accurate predictor of 6MWD recovery in the early post-transplant period. The cutoff point for ΔKES calculated using the Youden index was - 1.17 Nm/kg. CONCLUSIONS: The results of this study emphasize the importance of the need for programs designed to prevent muscle weakness in the early period after allo-HSCT. The results from markers of recovery of exercise tolerance are promising and can be used for patient education in rehabilitation programs after allo-HSCT.

ABSTRACT

INTRODUCTION: Hip osteoarthritis (OA) with acetabular dysplasia negatively affects pelvic alignment and muscle function. We aimed to investigate the changes in muscle atrophy and fatty infiltration of the hip and trunk muscles 1 year after total hip arthroplasty (THA) in patients with hip OA with acetabular dysplasia. METHODS: This study included 51 female patients who underwent THA for unilateral hip OA with acetabular dysplasia. The cross-sectional area (CSA) and muscle density of the gluteus maximus, gluteus medius, gluteus minimus, piriformis, iliopsoas, rectus abdominis, and abdominal oblique muscles using computer tomography and pelvic inclination angle using radiographs were assessed before and 1 year after THA. RESULTS: At the 1-year follow-up, the CSA and muscle density of the gluteus medius (2,078 to 2,522 mm2 and 30.3 to 39.4 hounsfield units [HU]), iliopsoas (715 to 901 mm2 and 40.3 to 50.8 HU), and rectus abdominis (336 to 363 mm2 and 28.6 to 30.6 HU) of the affected limb had increased significantly (P < 0.05). The CSA and muscle density of the gluteus maximus (2,429 versus 2,884 mm2 and 23.7 versus 32.6 HU), gluteus minimus (636 versus 785 mm2 and 14.3 versus 37.1 HU), piriformis (505 versus 607 mm2 and 23.4 versus 31.6 HU), and iliopsoas (901 versus 997 mm2 and 50.8 versus 54.5 HU) in the affected limb were lower than those in the unaffected limb (P < 0.01). Postoperatively, the CSA and muscle density of the rectus abdominis were not significantly different between the limbs, and the pelvic inclination angle (35.2° to 32.1°, P < 0.01) was significantly decreased. DISCUSSION: Compared with the nonoperated limb, substantial atrophy and fatty infiltration of most hip muscles persisted in the operated limb 1 year after THA in patients with acetabular dysplasia; asymmetry in the rectus abdominis muscle fully resolved. In patients with acetabular dysplasia, the surgical technique and postoperative rehabilitation should be further considered to optimize hip muscle recovery.

ABSTRACT

BACKGROUND: Total knee arthroplasty (TKA) is commonly performed to reduce knee pain and improve physical function. Compared with the values for healthy, age-matched women, previous studies have reported large deficits in functional ability, such as muscle strength and ambulatory ability, in women 1 year post-TKA. Ambulatory ability is to move around, particularly by walking and is clinically assessed by the timed up and go test (TUG). AIM: This study aimed to clarify the characteristics of knee functions in female patients whose ambulatory ability recovered to a normal level at 1 year after TKA. METHODS: This cross-sectional study included 151 female patients who underwent TKA. The muscle strength of the lower extremity was measured, and the 2011 Knee Society Scoring (2011 KSS) system was used postoperatively. The TUG was conducted to assess ambulatory ability after TKA; then the patients were classified into the fast and slow ambulation groups based on previously reported gait-speed values of healthy female individuals. Then, we identified significant indicators of ambulatory ability at 1 year after TKA. RESULTS: Forty-nine percent of patients after TKA achieved the level of ambulatory ability of a healthy female. Logistic regression analysis identified that the non-operative side knee extensor strength and the functional activity score, as assessed by the 2011 KSS, were variables significantly associated with the mid-term ambulatory ability after TKA. CONCLUSION: Female patients with high non-operative knee extensor strength and a functional activity score at 1 year postoperatively can achieve better ambulatory ability than those of healthy, age-matched females.

ABSTRACT

ABSTRACT: The purpose of this study is to investigate the predictive factors of home discharge for rehabilitation patients with cancer bone metastasis.Cancer patients with bone metastasis who underwent rehabilitation between April 2014 and March 2017 were retrospectively enrolled. Data on discharge destination were collected from medical records as outcomes. Multiple regression analyses were carried out to investigate the predictive factors of home discharge.Ninety-eight patients (mean age: 68.6 years, 42 females and 56 males) were included. Fifty patients were discharged home, 38 patients were discharged to other facilities, and 10 patients died. There were no skeletal-related events among these patients during their hospital stay. The receiver-operating curve for the predictive factors for home discharge of the Barthel Index at admission, Eastern Cooperative Oncology Group Performance Status at admission, and number of immediate family members living at home were 60 points (area under the curve [AUC] = 0.74, sensitivity = 0.6400, 1-specificity = 0.2766), 2 score (AUC = 0.65, sensitivity = 0.5400, 1-specificity = 0.2222), and 1 family member (AUC = 0.65, sensitivity = 0.9592, 1-specificity = 0.7222), respectively.In order to plan for cancer patients with bone metastasis to be discharged home, it is important to take into consideration the patients' Barthel Index and Performance Status at the time of hospital admission and the number of immediate family members living at home.

ABSTRACT

BACKGROUND: Hip abductor weakness due to the progression of hip osteoarthritis (OA) commonly causes poor functional mobility. The hip abductor strength has also been identified as a clinically relevant factor for successful functional outcomes after total hip arthroplasty. OBJECTIVES: This study aimed to examine the functional characteristics related to hip abductor torque in patients with hip OA. DESIGN: A cross-sectional survey study. METHODS: One hundred and eight female patients with severe unilateral hip OA participated in this study. Hip abductor torque and pain were measured. The muscle cross-sectional area (CSA) and skeletal muscle density (SMD) of the gluteal muscles were also measured using computed tomography. To identify the hip parameters associated with hip abductor torque, multiple regression analysis was performed. The healthy model included the CSA and SMD of gluteus maximus, gluteus medius, and gluteus minimus; range of motion in hip abduction; age; and body mass index. The affected model included hip pain in addition to the healthy model. RESULTS: In the affected limb, multiple regression analysis identified pain and angle of hip abduction as factors that determine hip abductor torque (Adjusted R2 = 0.39). In contrast, our analysis identified CSA and SMD of the gluteus medius and SMD of the gluteus minimus as the significant variables related to hip abductor torque in the healthy limb (Adjusted R2 = 0.40). CONCLUSION: The findings of this study indicated that it is necessary to consider that hip pain may inhibit muscle exertion and contraction while training to improve the hip abductor torque in the affected limb.

ABSTRACT

PURPOSE: The purpose of this study was to clarify the independent factors related to patient-reported physical functioning (PF) scores at discharge of patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: A total of 103 patients who underwent allo-HSCT were included in this cross-sectional study. As a screening method, a single regression analysis was conducted with the PF domain in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at discharge as the dependent variable, and body mass index, adverse events related to HSCT, and objective physical functions as independent variables. Multiple regression analysis was performed with PF as the dependent variable and variables that passed the screening by single regression analysis and confounders as independent variables. RESULTS: The mean PF score at discharge of the patients was 76.5 (standard deviation: 15.2). Based on the results of screening by the single regression analysis, length of stay, infections (+ / -), acute graft-versus-host disease grade, brief fatigue inventory score (BFI), knee extensor strength, and 6-min walk distance (6MWD) were included in the multiple regression analysis. BFI (B = - 11.94, p < 0.001) and 6MWD (per 10 m) (B = 0.56, p = 0.001) were extracted as significant independent variables governing the PF at discharge in the multiple regression model (adjusted R2 = 0.59). CONCLUSION: Higher exercise tolerance and lower fatigue in patients who underwent allo-HSCT were associated independently with patient-reported better PF scores at discharge.

ABSTRACT

As the proportion of long-term survivors after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is on the rise, it is essential to consider the significance of quality of life (QOL), including reintegration with society (returning to school or work). This retrospective cohort study aims to illustrate the precise epidemiology of social reintegration later after allo-HSCT and determine its predictive indicators. We enrolled 56 patients, and 40 patients (71%) attained social reintegration at 2 years post-HSCT. Reintegration failure markedly correlated with an inferior performance status and concurrent chronic graft-versus-host disease. In non-reintegrated patients, the physical function at discharge measured by the 6-min walking distance (6MWD) was markedly decreased. On the multivariate risk analyses, sex (female; odds ratio (OR) 0.07; 95% confidence interval (CI) 0.01-0.54; p = 0.01), HCT-CI (≥ 2; OR 0.10; 95% CI 0.01-0.84; p = 0.03), and change in 6MWD (per 5% increase; OR 1.47; 95% CI 1.01-2.13; p = 0.04) were significant predictors of later social reintegration. This study suggests that a multidisciplinary strategy including rehabilitation is essential, especially in patients with poor predictive markers at an early phase, and we should consider suitable rehabilitation programs to prevent a decline in exercise tolerance and improve social reintegration and overall QOL in patients after allo-HSCT.

ABSTRACT

OBJECTIVE: The aim of this study was to identify which aspect of the preoperative lower limb functions is most likely to affect the functional mobility at 6 mos after total hip arthroplasty. DESIGN: The study subjects included 125 women who underwent total hip arthroplasty. Hip flexion and abduction angles, hip abductor and knee extensor strengths, and lower limb load were measured preoperatively. The Timed Up and Go test was performed 6 mos postoperatively. Then, patients were divided into fast or slow groups as per the comparison with the Timed Up and Go score of healthy women. RESULTS: Hip abductor strength and lower limb load on the nonoperative side were revealed as significant measurements that affected functional mobility after total hip arthroplasty according to stepwise multiple logistic regression analysis. Moreover, receiver operating characteristic curve analyses showed that the postoperative functional mobility was predicted by the lower limb load of the nonoperative side (cutoff point, 8.97 N/kg; sensitivity, 62.3%; specificity, 82.8%; and area under the curve, 77.5%). CONCLUSIONS: This study revealed that patients with preoperative hip abductor strength of greater than 0.66 Nm/kg and lower limb load of greater than 8.97 N/kg on the nonoperative side could achieve better functional mobility at 6 mos postoperatively than healthy women of the same age group.

ABSTRACT

PURPOSE: The purpose of this study was to retrospectively investigate the effect of the severity of acute graft-versus-host disease (GVHD) on physical function after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: 76 patients were included as subjects of this study. Severity of acute GVHD was classified according to the method defined by Grucksberg. To evaluate physical function, the knee extensor strength and six-minute walk distance (6MWD) were performed. RESULTS: Among these patients, 54% developed acute GVHD; of these, 32%, 54%, and 15% of patients had grade I, grade II, and grades III-IV GVHD, respectively. In the grade I-II groups, mild acute GVHD following allo-HSCT resulted in a gradual decline in physical function, which improved at discharge. However, in cases of severe acute GVHD, physical function deteriorated, implementation of rehabilitation became difficult, and the decline in physical function persisted even at discharge. CONCLUSION: These results indicate that severe acute GVHD negatively affects physical function leading to longer hospital days because of inadequate rehabilitation interventions.

ABSTRACT

This study aimed to characterize the effect of different running modes on serum irisin concentrations in rats. A total of 18, 10-week-old rats were divided into three groups; control group, 16° uphill running group (concentric exercise; CON) and, -16° downhill running group (eccentric exercise; ECC). The running group's rats ran on the inclined treadmill at 16 m/min, for a total of 90 min. Blood was drawn from the rats, 48 h after running, after which the rats were anesthetized. The serum concentrations of irisin were measured using enzyme-linked immunosorbent assays. Vastus intermedius was collected for immunohistochemical analysis. After multiple comparisons, the ECC showed a significantly high serum irisin concentration (ECC: 28.42 ± 6.31 ng/ml, CON: 21.27 ± 3.03 ng/ml) and a larger irisin antibody reactive cross-sectional area in vastus intermedius compared to the CON (p < 0.05). This is the first study to reveal that single bout downhill running increases serum irisin concentrations in rats.
