    PURPOSE: In this study, we aimed to evaluate the changes in and the relationship between lower limb muscle strength and physical function before and after medial meniscus posterior root (MMPR) repair. METHODS: Thirty-three patients who underwent MMPR repair were evaluated. Pain was evaluated with the numerical rating scale (NRS), and knee flexor/extensor muscle strength was assessed using a handheld dynamometer. Physical function was evaluated using a timed up and go (TUG) test. The NRS, knee flexor/extensor muscle strength, and TUG were compared preoperatively and 1 year postoperatively using the Wilcoxon signed-rank test. The correlation of patient characteristics, NRS score, knee flexor/extensor muscle strength, and preoperative TUG with the postoperative TUG was analyzed using Spearman's correlation coefficient. RESULTS: NRS (3.5 ± 2.1 to 0.1 ± 0.5 points), knee flexor strength (111.9 ± 50.2 to 146.7 ± 51.5 Nm), knee extensor strength (181.9 ± 92.8 to 256.9 ± 107.1 Nm), and TUG (12.3 ± 5.7 to 9.2 ± 2.2 s) all improved significantly from preoperatively to 1 year postoperatively (p < 0.001). The postoperative TUG was negatively correlated with the preoperative TUG (r = 0.578, p < 0.001), preoperative knee flexor muscle strength (r = - 0.355, p = 0.042), preoperative knee extensor muscle strength (r = - 0.437, p = 0.010), and postoperative knee extensor muscle strength (r = - 0.478, p = 0.004). CONCLUSION: In patients undergoing MMPR repair, surgery and rehabilitation significantly improve lower limb muscle strength and physical function. There was a significant correlation between lower limb muscle strength and TUG, and further strengthening of the lower limb muscles from the preoperative level is desirable to improve patients' physical function further.

    Research on postural control in patients with adolescent idiopathic scoliosis (AIS) has focused on static postural control, with few studies assessing dynamic postural control. We aimed to identify factors affecting index of postural stability (IPS), a dynamic postural control parameter, in patients with AIS. The participants comprised 50 female patients with AIS. We measured the IPS using stabilometry to evaluate dynamic postural control ability. We investigated age of the participants, major curve position (thoracic or thoracolumbar/lumbar), Cobb angle, and coronal balance. We then assessed the relationships between stabilometry parameters and other variables. IPS was analyzed with a linear regression model. Coronal balance, major curve position, and age each correlated with dynamic postural control ability. The Cobb angle showed no correlation with any of the parameters. Our results offer new insights into the assessment of postural control in patients with AIS.

    BACKGROUND: The purpose of this study was to examine two techniques for Carpal Tunnel Syndrome, mini-Open Carpal Tunnel Release (mini-OCTR) and Endoscopic Carpal Tunnel Release (ECTR), to compare their therapeutic efficacy. METHODS: Sixteen patients who underwent mini-OCTR in palmar incision and 17 patients who underwent ECTR in the wrist crease incision were included in the study. All patients presented preoperatively and at 1, 3, and 6 months postoperatively and were assessed with the Visual Analogue Scale (VAS) and the Disabilities of Arm, Shoulder and Hand Score (DASH). We also assessed the pain and cosmetic VAS of the entire affected hand or surgical wound, and the patient's satisfaction with the surgery. RESULTS: In the objective evaluation, both surgical techniques showed improvement at 6 months postoperatively. The DASH score was significantly lower in the ECTR group (average = 3 months: 13.6, 6 months: 11.9) than in the mini-OCTR group (average = 3 months: 27.3, 6 months: 20.6) at 3 and 6 months postoperatively. Also, the pain VAS score was significantly lower in the ECTR group (average = 17.1) than in the mini-OCTR group (average = 36.6) at 3 months postoperatively. The cosmetic VAS was significantly lower in the ECTR group (average = 1 month: 15.3, 3 months: 12.2, 6 months: 5.41) than in the mini-OCTR group (average = 1 month: 33.3, 3 months: 31.2, 6 months: 24.8) at all time points postoperatively. Patient satisfaction scores tended to be higher in the ECTR group (average = 3.3) compared to the mini-OCTR group (average = 2.7). CONCLUSIONS: ECTR in wrist increase incision resulted in better pain and cosmetic recovery in an early postoperative phase compared with mini-OCTR in palmar incision. Our findings suggest that ECTR is an effective technique for patient satisfaction.

    Abstract

    Progression of the physical weakness during neoadjuvant therapy (NAT) in patients with esophageal or gastroesophageal junction cancer is a serious problem; however, prehabilitation during NAT has the potential to overcome the unmet need. Nevertheless, systematic reviews on this topic have not been summarized. Therefore, this systematic review aimed to determine prehabilitation’s effectiveness, acceptability, and safety during NAT for patients with esophageal or gastroesophageal junction cancer. An electronic search was performed in the MEDLINE, Web of Science, CENTRAL, CINAHL, and PEDro databases. A meta-analysis was conducted to assess the effectiveness of prehabilitation during NAT, along with a descriptive analysis of acceptance and safety. This study analyzed data from three randomized controlled trials (RCTs) and nine non-RCTs involving 664 patients. The meta-analysis of two RCTs demonstrated that prehabilitation during NAT may be more effective than usual care in enhancing tolerance to NAT and grip strength; moreover, one RCT and three non-RCTs revealed that prehabilitation may reduce the risk of postoperative complications. The adherence rates for exercise programs in two RCTs and seven non-RCTs were 55–76%. Additionally, two studies reported a 76% adherence rate for multimodal prehabilitation programs, including exercise, dietary, and psychological care. Six studies reported no serious prehabilitation-related adverse events during NAT. Prehabilitation during NAT may be a safe and beneficial intervention strategy for patients with esophageal or gastroesophageal junction cancer. However, the investigation of strategies to enhance adherence is essential. Furthermore, additional high-quality RCTs are needed to examine the effect of prehabilitation during NAT.

    INTRODUCTION: The association of changes in skeletal muscle mass and quality during the waiting time with outcomes of lung transplantation (LT) remains unclear. We aimed to examine the association of changes in skeletal muscle mass and quality during the waiting time, as well as preoperative skeletal muscle mass and quality, with outcomes of LT. METHODS: This study included individuals who underwent LT from brain-dead donors. Skeletal muscle mass (cm2 /m2 ) and quality (mean Hounsfield units [HU]) of the erector spinae muscle at the 12th thoracic level were evaluated using computed tomography. Preoperative skeletal muscle mass and quality, and their changes during the waiting time were calculated. We evaluated the associations among mechanical ventilation (MV) duration, intensive care unit (ICU) length of stay (LOS), hospital LOS, 6-minute walk distance at discharge, and 5-year survival after LT. RESULTS: This study included 98 patients. The median waiting time was 594.5 days (interquartile range [IQR], 355.0-913.0). The median changes in skeletal muscle mass and quality were -4.4% (IQR, -13.3-3.1) and -2.9% (IQR, -16.0-4.1), respectively. Severe low skeletal muscle mass at LT was associated with prolonged ICU LOS (B = 8.46, 95% confidence interval [CI]: .51-16.42) and hospital LOS (B = 36.00, 95% CI: 3.23-68.78). Pronounced decrease in skeletal muscle mass during the waiting time was associated with prolonged MV duration (B = 7.85, 95% CI: .89-14.81) and ICU LOS (B = 7.97, 95% CI: .83-15.10). CONCLUSION: Maintaining or increasing skeletal muscle mass during the waiting time would be beneficial to improve the short-term outcomes of LT.

    BACKGROUND: Physical activity has the potential to promote tumor regression in patients with esophageal cancer receiving neoadjuvant chemotherapy (NAC); however, the benefits of light-intensity physical activity (LIPA) are unclear. This study aimed to investigate the impact of LIPA on tumor regression in male patients with esophageal cancer during NAC and its optimal cutoff value. METHODS: This retrospective single-center observational study included all male patients who underwent NAC or curative esophagectomy. We assessed the physical activity of patients using an accelerometer and calculated the time spent on LIPA. Tumor regression was defined as grade ≥ 1b according to the Japanese classification of esophageal cancer. The impact of LIPA on tumor regression was analyzed using multivariate analysis, and the optimal cutoff value was identified using the receiver operating characteristic curve. RESULTS: Sixty-nine male patients with esophageal cancer who underwent NAC were analyzed. The mean age was 68 years, mean body mass index was 22.4, and 80% of the patients were diagnosed with clinical stage 3 or 4 disease. Every extra 30-min increase in LIPA during the treatment phase was associated with tumor regression (adjusted OR 1.41 [1.02-2.04]). The optimal cutoff value of LIPA was 156.11 min/day, and patients with rich LIPA (≥ 156.11 min/day) were less likely to suffer from anorexia and malnutrition during NAC. CONCLUSION: This study demonstrated that LIPA during NAC has a potential of promoting tumor regression with a cutoff value of 156.5 min/day. Further clinical research is required to determine the prognostic benefits of LIPA in patients receiving NAC.

    BACKGROUND: This study aimed to assess quadriceps muscle strength after medial meniscus (MM) posterior root repair and determine its relationship with clinical scores and MM extrusion (MME). METHODS: Thirty patients who underwent pullout repair for MM posterior root tear and were evaluated for quadriceps muscle strength preoperatively and at 1 year postoperatively were included in this study. Quadriceps muscle strength was measured using the Locomo Scan-II instrument (ALCARE, Tokyo, Japan). MME and clinical scores (i.e., Knee Injury and Osteoarthritis Outcome Score [KOOS], International Knee Documentation Committee score, Lysholm score, Tegner score, and visual analog scale pain score) were evaluated preoperatively and at 1 year postoperatively, and second-look arthroscopy was performed at 1 year postoperatively. Wilcoxon's signed-rank test was used to compare each measure pre- and postoperatively. Pearson's correlation coefficient was used to assess the correlation with quadriceps muscle strength values. Multiple regression analysis was performed to identify factors associated with the change in MME (ΔMME). RESULTS: Second-look arthroscopy confirmed continuity of the posterior root in all patients. The quadriceps muscle strength measured at 1 year postoperatively (355.1 ± 116.2 N) indicated significant improvement relative to the quadriceps muscle strength measured preoperatively (271.9 ± 97.4 N, p < 0.001). The MME at 1 year postoperatively (4.59 ± 1.24 mm) had progressed significantly relative to the MME preoperatively (3.63 ± 1.01 mm, p < 0.001). The clinical scores at 1 year postoperatively were improved significantly relative to the scores preoperatively (p < 0.001). The postoperative quadriceps muscle strength was correlated with ΔMME (correlation coefficient = -0.398, p = 0.030), and the change in quadriceps muscle strength was correlated with the KOOS-Quality of Life (correlation coefficient = 0.430, p = 0.018). Multiple regression analysis showed that the postoperative quadriceps muscle strength had a significant effect on ΔMME even when the body mass index and time from injury to surgery were included. CONCLUSIONS: After MM posterior root repair, patients with greater quadriceps muscle strength showed less MME progression. In addition, patients with greater improvement in quadriceps muscle strength had better clinical scores; therefore, continued rehabilitation aimed at improving quadriceps muscle strength after MM posterior root repair is recommended.

    PURPOSE: The aim of this study was to compare the clinical outcomes of different subtypes of type 2 medial meniscus posterior root tears following transtibial pullout repair. METHODS: In total, 147 patients (mean age: 66.2 ± 8.3 years) who were diagnosed with type 2 medial meniscus posterior root tears and underwent transtibial pullout repair were included. Patients were divided into 2A (n = 31), 2B (n = 90), and 2C (n = 26) groups according to tear type. Clinical outcomes were assessed pre-operatively and at second-look arthroscopy using the Knee injury and Osteoarthritis Outcome Score. The meniscal healing status was evaluated at second-look arthroscopy. Medial meniscus extrusion was calculated using magnetic resonance imaging pre-operatively and at second-look arthroscopy. RESULTS: No significant differences in pre-operative or post-operative clinical scores were observed between each subtype, although clinical scores improved post-operatively for each subtype. Significant differences were noted in the anteroposterior width of the bridging tissues at second-look arthroscopy (2A, 7.1 ± 1.2; 2B, 6.2 ± 1.7; and 2C, 6.2 ± 1.7 mm; p = 0.045); type 2A tears were the widest. There was a significant difference in post-operative medial meniscus extrusion (2A, 3.2 ± 0.9; 2B, 4.0 ± 1.2; and 2C, 4.0 ± 1.4 mm; p = 0.004) and its progression (2A, 0.7 ± 0.6; 2B, 1.2 ± 0.8; and 2C, 1.2 ± 0.8 mm; p = 0.008), and type 2A tears were the shortest. CONCLUSION: Although there was no significant difference in the post-operative clinical scores among different type 2 tears in the short term, type 2A tears showed better healing and medial meniscus extrusion progression prevention, thus indicating the usefulness of classifying tear type in estimating post-operative outcomes.

    This retrospective study aimed to investigate the validity of a 30-sec chair stand test (CS-30) as a simple test to assess exercise tolerance and clinical outcomes in 53 Japanese patients with esophageal cancer. There was a strong correlation between the results of CS-30 and the 6-min walk test (6MWT), the gold standard for assessing exercise tolerance (r=0.759). Furthermore, fewer patients whose CS-30 score was greater than 16 (the cutoff value defined based on 6MWT) experienced pneumonia in their postoperative course. These results suggest that exercise tolerance could be assessed using CS-30, and its cutoff value may be useful in predicting postoperative pneumonia risk.

    Objective: This study aimed to investigate the association between overall survival (OS) and activities of daily living (ADL) in patients with skeletal-related events. In this study, 265 patients whose clinical parameters were available before radiotherapy were investigated. Methods: Age, sex, ADL, pain, the primary site, spinal level of bone metastases, spinal instability, treatment strategy, including chemotherapy or palliative treatment, and OS were investigated. ADL patients with a Barthel index of ≥90 were classified as the high ADL group, while those with a score < 90 were classified as the low ADL group. For OS, patients surviving ≥160 days were classified as the non-poor prognosis group, and those who survived <160 days were classified as the poor prognosis group. Results: Age, sex, ADL, pain, the primary site, and treatment strategy for OS were different between the two groups (p < 0.1). Logistic regression analysis revealed that ADL, the primary site, and treatment strategy were significant predictors of OS (p < 0.05). High ADL, breast cancer, and chemotherapy had a positive effect on OS. Conclusions: It is suggested that improvements may be obtained by performing rehabilitation interventions to maintain and improve ADL, by constructing a system for monitoring spinal bone metastases with images before ADL decreases, and by performing interventions such as changes in treatment methods such as RT or surgery at appropriate times.

    This study examined changes in the quality of life (QOL), as well as the factors affecting QOL, among patients with painful spinal bone metastases without paralysis for 1 month after radiotherapy. METHODS: This study included 79 participants (40 male and 39 female; median age, 65 (42-88) years) who had undergone radiotherapy for painful spinal bone metastases without paralysis. Patients' age, sex, activities of daily living (Barthel index), pain, spinal instability (spinal instability neoplastic score [SINS]), and QOL (EORTC QLQ-C30) were investigated. RESULTS: Having an unstable SINS score was a positive factor for global health status (p < 0.05). The improvement in activities of daily living and response to pain were positive factors for physical function (p < 0.05). A positive effect on emotional function was confirmed among female patients (p < 0.05). CONCLUSION: Engaging in rehabilitation along with radiotherapy leads to improvements in QOL for patients with spinal bone metastases.

    Our previous studies have shown that spa therapy can reduce subjective symptoms and improve ventilatory function in patients with chronic obstructive pulmonary disease (COPD). The aim of this study is to measure the effects of spa therapy on walking distance during the six-minute walk test in patients with COPD. Twenty-five COPD patients hospitalized for pulmonary rehabilitation at our hospital were included in this study. Twenty-two patients were male and 3 patients were female. Two patients had stage I, 9 patients had stage II, and 14 patients had stage III COPD, according to the Global Initiative for Chronic Obstructive Lung Disease. We offered complex spa therapy (swimming training in a hot spring pool, inhalation of iodine salt solution, and fango therapy) in all patients for 4 weeks. Ventilatory function, six-minute walk distance, oxygen saturation and Borg scale were measured. Vital capacity (VC) was significantly improved by spa therapy at 4 weeks (p<0.05). The values of forced vital capacity (FVC), forced expiratory volume in one second (FEV1.0), forced expiratory flow after 75% of expired FVC (FEF75), forced expiratory flow after 50% of expired FVC (FEF50), forced expiratory flow after 25% of expired FVC (FEF25), mean expiratory flow during the middle half of the FVC (FEF25-75), residual volume (RV), functional residual capacity (FRC), peak expiratory flow (PEF) and diffusing capacity for carbon monoxide (DLco) showed a tendency to increase, however the increase in the 10 parameters was not significant. The values of six-minute walk distance before and after spa therapy were 288±106m and 323±114m, respectively (p<0.05). There was a significant decrease in values of maximum Borg Scale values (p<0.05). The values of minimum oxygen saturation and the values of oxygen saturation at rest slightly increased, but not significantly. The change of six-minute walk distance correlated with change of VC (r=0.545; p<0.05), with change of FVC (r=0.628; p<0.05), with change of FEV1.0 (r=0.559; p<0.05), with change of FEF50 (r=0.480; p<0.05), with change of minimum oxygen saturation (SpO2) (r=0.554; p<0.05) and with change of SpO2 at rest (r=0.445; p<0.05). We found that spa therapy induced improvements in ventilatory dysfunction and six-minute walk distance in patients with COPD. The results from this study reveal that spa therapy may improve disease control and exercise tolerance in patients with COPD.

    We examined whether ambulatory ability before surgery might influence the post-operative D-dimer level after total hip arthroplasty (THA). One hundred two patients with hip osteoarthritis receiving THA were included in the current study. The patients were all female, and their ages ranged from 45 to 81 (average 65.0 +- 9.3 years). Age, operated side, body mass index (BMI), disease duration before surgery, pre-operative pain evaluated by visual analogue scale (VAS), total cholesterol value, maximal circumference of the lower leg of the operated side, and timed "Up & Go"test (TUG) before surgery, were retrospectively investigated to examine their relationship with D-dimer levels on post-operative day 7. Patients were divided into 2 groups according to the D-dimer value: over 10 microg/ml (Group D), and under (Group N). Patients in group D (N= 52)were older, had a higher BMI, and had less ambulatory ability than patients in group N (N= 50). As age showed a relationship with the D-dimer value on the 7th day and TUG results, patients in the 2 groups were further subdivided into 50's, 60's, and 70's age brackets. In the 50's bracket, patients in group D had higher BMI than patients in group N, but time for TUG was not significantly different. In the 60's and 70's bracket, patients in group D had less ambulatory ability than patients in group N, but the time for TUG was not directly correlated with the D-dimer value. The results suggest that pre-operative low ambulatory ability in patients with osteoarthritis over 60 years might influence the postoperative D-dimer after THA, indicating the potential risk for post-operative deep venous thrombosis.

    Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus length per environmental area, environmental area, rectangle area, root mean square area, and the ratio of sway with eyes closed to sway with eyes open. Knee flexor and extensor power and toe flexor and abductor power were the measures representing lower extremity muscle power. The increase in sway with the eyes closed was more marked during one-leg standing than two-leg standing, as expected. We found that 36 of 57 subjects (62%) were unable to maintain one-leg standing with their eyes closed, and this failure correlated with marked body sway (P = 0.0086). Many subjects had one leg that was classified as stable and the other leg classified as unstable. Clearly, testing of both legs alternately with eyes closed is necessary to measure the full range of sway in subjects. Lower extremity muscle power did not appear to be the dominant factor in maintaining balance in these young subjects.

    Rheumatoid arthritis (RA) is often associated with deformities of the feet, and foot pain often arises in the talonavicular joint of patients with RA. The object of this study was to assess the relationship between magnetic resonance imaging (MRI) findings of the talonavicular joint and walking ability. The subjects were 35 RA patients (10 feet in 5 males and 56 feet in 30 females) aged 34-87 years (mean: 70 years +/- 12.1), with a disease duration from 1-54 years (mean: 14 years +/- 12.1). MRI findings were classified as follows: Grade 1, almost normal; Grade 2, early articular destruction; Grade 3, moderate articular destruction; Grade 4, severe articular destruction; and Grade 5, bony ankylosis dislocation. Walking ability was classified into one of 9 categories ranging from normal gait to bedridden status according to the system of Fujibayashi. As the grade of MRI images became higher the walking ability decreased, and these parameters showed a correlation by Spearman's rank correlation coefficient analysis (P = 0.003). Thus, in the present cohort group of patients with RA, the deterioration of walking ability increased with the severity of destruction of the talonavicular joint.
