Evidence and Recommendations for Acute Stroke Rehabilitation from the Japan Stroke Society: Abridged Secondary Publication of the Japanese-language Version.

Objectives: In Japan, acute stroke rehabilitation has been expanding more steadily than previously with the nationwide establishment of primary stroke centers. However, Japan previously had no established guidelines for the rehabilitation. Consequently, rehabilitation programs and the provision systems for acute stroke varied among the facilities. To equalize and standardize acute stroke rehabilitation in Japan, it is necessary to develop clinical recommendations for rehabilitation. Therefore, the rehabilitation project team of the Japan Stroke Society aimed to develop the first recommendations for acute stroke rehabilitation in Japan. Methods: The recommendations are based on the results of a survey on the current status of acute stroke rehabilitation at primary stroke centers in Japan, which was completed in 2022, and on a literature review conducted by the rehabilitation project team. Results: The recommendations consist of 19 clinical questions regarding the following topics of acute stroke rehabilitation: (1) head elevation and mobilization training, (2) acute complications, (3) training time and frequency for acute stroke rehabilitation, (4) dysphagia in the acute phase, and (5) acute rehabilitation during pandemics of novel and re-emerging infections, particularly novel coronavirus disease 2019 (COVID-19). The team members agreed on all answers for these 19 clinical questions. Conclusions: These recommendations suggest broad principles of rehabilitative intervention in the acute phase of stroke. In the near future, it is expected that the dissemination of these recommendations will result in an increase in the quality of acute stroke rehabilitation in Japan.

Calculation of trunk muscle mass and trunk muscle quality indices for walking independence in asian patients with hip fractures.

BACKGROUND & AIMS: This study aimed to investigate the association between trunk muscle mass and muscle quality, as evaluated by bioelectrical impedance analysis (BIA), and the ability to walk independently in patients with hip fractures. Cutoff values for quantitative and qualitative indicators of the trunk muscles were also calculated. METHODS: This study included 181 patients with hip fractures who were admitted to a convalescent rehabilitation ward. Trunk muscle mass and phase angle of the participants were evaluated on admission. The phase angle in this study was defined as the trunk muscle quality index (TMQI). Patients were classified into the independent (functional independence measure [FIM]-walk score ≥6; n = 101) and non-independent (FIM-walk score ≤5; n = 80) walking groups according to the FIM mobility scores at discharge. RESULTS: The independent group had a higher FIM gain than the non-independent group (37.0 ± 13.6 vs. 27.1 ± 13.5, p < 0.001). Logistic regression analysis showed that the trunk muscle mass index (TMI) and TMQI were associated with the ability to walk independently. Furthermore, cutoff values of TMI and TMQI for male and female to estimate the ability to walk independently were 6.5 kg/m2 and 5.7 kg/m2, and 4.5° and 3.4°, respectively. CONCLUSION: TMI and TMQI are related to the ability to walk independently in patients with hip fractures. These results suggest the importance of improving trunk muscle mass and muscle quality during rehabilitation of patients with hip fractures.

Observations of cold-induced vasodilation in persons with spinal cord injuries.

STUDY DESIGN: Acute experimental study. OBJECTIVES: Cold-induced vasodilation is a local mechanism of protection against frostbite in non-injured persons. We assessed whether an increase in skin blood flow (SkBF) during local cooling (LC) was observed in individuals with spinal cord injuries (SCIs) and if the response patterns differed between region levels or sites. SETTING: Laboratory of Wakayama Medical University and the affiliated clinics, Japan. METHODS: A local cooler device (diameter 4 cm) was placed on the chest (sensate) and right thigh (non-sensate) in persons with cervical (SCIC; n = 9) and thoracolumbar SCIs (SCITL; n = 9). After the surface temperature under the device was controlled at 33 °C for 10 min (baseline), LC (-0.045 °C/s) was applied and the skin temperature was maintained at 15 and 8 °C for 15 min of each stage. SkBF (laser Doppler flowmetry) was monitored using a 1-mm needle-type probe inserted into its center. RESULTS: The percent change in SkBF (%ΔSkBF) on the chest remained unchanged until the end of 15 °C stage; thereafter, it increased to a level at least 70% greater than the baseline during the 8 °C stage in both groups. The %ΔSkBF on the thigh in both SCIC and SCITL notably increased from 8 and 6 min respectively, during the 8°C stage, compared to 1 min before the stage; however, it did not exceed the baseline level. CONCLUSIONS: An increase in SkBF during LC was observed both in the sensate and non-sensate areas in SCIs, although the magnitude was larger in the sensate area.

Increase in Serum Interleukin-1 Receptor Antagonist (IL-1ra) Levels after Wheelchair Half Marathon Race in Male Athletes with Spinal Cord Injury.

Exercise increases the serum level of interleukin-6 (IL-6), which in turn stimulates the production of various inflammatory cytokine antagonists, such as interleukin-1 receptor antagonist (IL-1ra). Individuals with cervical spinal cord injury (CSCI) are at high risk of inflammatory conditions. This study compared the effects of wheelchair half marathon on the immune system of male athletes with CSCI and those with thoracic/lumber spinal cord injury (SCI). Neutrophil count, IL-1ra, IL-6, and various endocrine parameters were measured before, immediately and 1 h after the race in five CSCI and six SCI who completed the wheelchair marathon race. The percentage of neutrophils was significantly higher in CSCI immediately and 1 h after the race, compared with the baseline, and significantly higher in SCI at 1 h after the race. IL-6 was significantly higher immediately and 1 h after the race in SCI, whereas no such changes were noted in IL-6 in CSCI. IL-1ra was significantly higher at 1 h after the race in both SCI and CSCI. The race was associated with an increase in IL-1ra in both CSCI and SCI. These findings suggest wheelchair half marathon race increases IL-1ra even under stable IL-6 status in male CSCI individuals, and that such post-race increase in IL-1ra is probably mediated through circulatory neutrophils.

White matter microstructural alterations in patients with neuropathic pain after spinal cord injury: a diffusion tensor imaging study.

Background: Through contrastive analysis, we aimed to identify the white matter brain regions that show microstructural changes in patients with neuropathic pain (NP) after spinal cord injury (SCI). Methods: We categorized patients with SCI into NP (n = 30) and non-NP (n = 15) groups. We extracted diffusion tensor maps of fractional anisotropy (FA) and mean (MD), axial (AD), and radial (RD) diffusivity. A randomization-based method in tract-based spatial statistics was used to perform voxel-wise group comparisons among the FA, MD, AD, and RD for nonparametric permutation tests. Results: Atlas-based analysis located significantly different regions (p < 0.05) in the appointed brain atlas. Compared to the non-NP group, the NP group showed higher FA in the posterior body and splenium of the corpus callosum and higher AD in the corpus callosum, internal capsule, corona radiata, posterior thalamic radiation, sagittal stratum, external capsule, cingulum, fornix/stria terminalis, superior longitudinal fasciculus, and uncinate fasciculus. Conclusion: The results demonstrated that compared with the non-NP group, NP pathogenesis after SCI was potentially related to higher values in FA that are associated with microstructural changes in the posterior body and splenium of the corpus callosum, which could be regarded as central sensitization or network hyperexcitability.

Case report: Rehabilitation course in thrombocytopenia, anasarca, fever, reticulin fibrosis/renal failure, and organomegaly syndrome complicated by cerebral infarction in the left parabolic coronary region.

Although thrombocytopenia, anasarca, fever, reticulin fibrosis/renal failure, and organomegaly (TAFRO) syndrome was first reported in 2010, its pathogenesis and prognosis are still unknown. Moreover, reports on rehabilitation in patients with TAFRO are limited. In severe cases, dyspnea and muscle weakness could impede improvements in activities of daily living (ADL). However, reports on exercise intensity showed no worsening of TAFRO within the load of 11-13 on the Borg scale. Herein, we describe the rehabilitation and progress in a 61-year-old woman with TAFRO syndrome complicated by cerebral infarction from early onset to discharge. After cerebral infarction onset in the perforating artery, she was admitted to the intensive care unit due to decreased blood pressure and underwent continuous hemodiafiltration. Two weeks following transfer to a general ward, the patient started gait training using a brace due to low blood pressure, respiration, and tachycardia. After initiating gait training, increasing the amount of training was difficult due to a high Borg scale of 15-19, elevated respiratory rate, and worsening tachycardia. Furthermore, there was little improvement in muscle strength on the healthy side after continuous training, owing to long-term steroid administration. On day 100 after transfer, the patient was discharged home with a T-cane gait at a monitored level. The patient had severe hemiplegia due to complications with severe TAFRO syndrome delaying early bed release and gait training; tachycardia; and respiratory distress. Additionally, delayed recovery from muscle weakness on the non-paralyzed side made it difficult for the patient to walk and perform ADLs. Despite these issues, low-frequency rehabilitation was useful. However, low-frequency rehabilitation with gait training, using a Borg scale 15-19 orthosis, did not adversely affect the course of TAFRO syndrome.

Application of Tinel's test combed with clinical neurosensory test distinguishes spontaneous healing of lingual nerve neuropathy after mandibular third molar extraction.

BACKGROUND: Extraction of the mandibular third molar, the most frequent and important surgical procedure in the clinical practice of oral surgery, is associated with the risk of injury of the lingual nerve. Neuropathy of the lingual nerve poses diagnostic challenges regarding the transient or permanent nature of the injury. No consensus or criteria have been established regarding the diagnosis of lingual nerve neuropathy. We applied both Tinel's test and clinical neurosensory testing together, which can be easily used at the bedside in the early stages of injury. Therefore, we propose a new method to differentiate between lesions with the ability to heal spontaneously and those that cannot heal without surgery. RESULTS: Thirty-three patients (29 women,  4 men; mean age, 35.5 years) were included in this study. For all patients, the median interval between nerve injury and initial examination was 1.6 months and that between nerve injury and the second examination before determining the need for surgical management was 4.5 months. The patients were assigned to either group A or B. The spontaneous healing group (group A, n = 10) revealed a tendency for recovery within 6 months after tooth extraction. In this group, although there were individual differences in the degree of recovery, a remarkable tendency for recovery was observed based on clinical neurosensory testing in all cases. None of the patients were diagnosed with allodynia. In seven cases, the Tinel test result was negative at the first inspection, and in three cases, the result changed to negative at the second inspection. Conversely, in group B(n = 23), no recovery trend was observed with regard to clinical neurosensory testing, and nine patients had allodynia. Further, the Tinel test result was positive for all patients in both examinations. CONCLUSIONS: Our findings indicate that in case of transient lingual nerve paralysis, clinical neurosensory testing findings deteriorate immediately after tooth extraction and gradually recover, while Tinel's test shows a negative result. Using Tinel's test and clinical neurosensory testing together enabled early and easy identification of the severity of the lingual nerve disorder and of lesions that would heal spontaneously without surgical management.

Effects of continuous bicycle ergometer and step exercises from admission to discharge in a patient with myelodysplastic syndrome undergoing myeloablative conditioning and hematopoietic stem cell transplantation: A case report.

BACKGROUND: In myelodysplastic syndromes (MDS), in addition to disease-related symptoms, many adverse events are associated with anticancer agents, myeloablative conditioning (MAC), and allogeneic hematopoietic stem cell transplantation (allo-HSCT). Isolation and bed rest in a clean room severely limit physical activity, resulting in cardiopulmonary and muscle weakness. In addition, post-transplant patients may experience general fatigue, gastrointestinal symptoms, and infections associated with a weakened immune system, as well as graft-versus-host disease, which causes further decline in physical function and activities of daily living (ADL). Most reports on the rehabilitation of patients with hematopoietic tumors involve interventions before and after chemotherapy or transplantation. However, an important issue is to establish effective and feasible exercise programs in a clean room setting, where activity is severely limited and physical function is most likely to decline. CASE REPORT: This case report describes the treatment progress of a 60-year-old man with MDS and thrombocytopenia scheduled to receive MAC and allo-HSCT, who continued bicycle ergometer and step exercises from admission to discharge. The patient was admitted for allo-HSCT, and on day 4, he started bicycle ergometer and step exercise in a clean room and continued until discharge. As a result, exercise tolerance and lower-extremity muscle strength were maintained at the time of hospital discharge. Furthermore, the patient was able to continue rehabilitation in a restricted environment without adverse events. CONCLUSIONS: The rehabilitation and treatment course of this case may provide valuable information for patients with MDS and thrombocytopenia.

Effects of Physiatrist and Physiotherapist-supervised Therapeutic Exercise on Physical Function in Frail Older Patients with Multimorbidity.

Objectives: : To ease the burden on care facilities, there is a need to reduce the number of frail older people with multiple chronic and non-communicable diseases (multimorbidity) that require long-term care. We investigated the effects of therapeutic exercise in rehabilitation treatment for older individuals with frailty and multimorbidity. Methods: : We performed 4 weeks of inpatient rehabilitation treatment for frail older patients with multimorbidity. The therapeutic exercise was performed based on whole-body evaluations by qualified physiatrists and physiotherapists. Sixty-minute sessions were conducted twice a day and six times a week in accordance with the American College of Sports Medicine guidelines. Physical functions (grip strength, isometric lower muscle strength, 10-m walking test, and 6-min walking test) were measured at admission and discharge. Results: : Of the 33 patients, 8 were unable to complete physical function evaluations, and 1 patient had a stress fracture of the right calcaneus beyond the rehabilitation time. Twenty-four patients were included in the analysis. Compared to the admission period, significant improvements were observed for all evaluated parameters post-therapy (P < 0.05). However, no significant correlation was found between the number of chronic diseases and changes to physical function (P > 0.05). Conclusions: : Physical function of frail older individuals with multimorbidity improves through rehabilitation treatments supervised by physiatrists and physiotherapists. The number of chronic illnesses and the improvements in physical function were not related. Therefore, rehabilitation treatments for older patients may target both frailty and multimorbidity. Our results will aid in the rehabilitation treatment plans for this demographic.

Long-Term Safety and Efficacy of Mirogabalin for Central Neuropathic Pain: A Multinational, Phase 3, 52-Week, Open-Label Study in Asia.

INTRODUCTION: Central neuropathic pain (CNeP) is difficult to treat and has diverse etiology, including spinal cord injury (CNePSCI), Parkinson's disease (CNePPD), and central post-stroke pain (CPSP). The safety and efficacy of mirogabalin have been demonstrated in short-term trials, including patients with CNePSCI. The objective of our study was to confirm the safety/efficacy of mirogabalin in patients with CNePPD and CPSP, and obtain long-term data for CNePSCI. METHODS: This 52-week, open-label extension of a previous randomized controlled study was conducted across Japan, Korea, and Taiwan. Patients with CNePSCI, CNePPD, or CPSP received twice daily (BID) 5-10 mg mirogabalin for a 4-week titration period, after which the dosage was maintained for 47 weeks at a maximum of 15 mg BID, followed by a 1-week taper period receiving the same dose but only administered once daily. The primary endpoint was safety, assessed primarily by incidence and severity of treatment-emergent adverse events (TEAEs). Efficacy was assessed in a post hoc analysis of data obtained by the short-form McGill Pain Questionnaire (SF-MPQ). RESULTS: Of the 210 patients enrolled, 106, 94, and 10 had CNePSCI, CPSP, and CNePPD, respectively. The mean overall age of patients was 62.9 years, and most patients were male and of Japanese ethnicity. TEAEs occurred in 84.8% of patients, the most common being somnolence (16.7%), peripheral edema (12.4%), edema (11.4%), nasopharyngitis (11.0%), and dizziness (7.6%). Most TEAEs were mild. Severe and serious TEAEs occurred in 6.2% and 13.3% of patients, respectively. All patient groups experienced reductions in SF-MPQ visual analog scores for pain: mean ± standard deviation changes from baseline at week 52 were -2.3 ± 21.13 mm (CNePSCI), -17.0 ± 24.99 mm (CPSP), and -17.1 ± 35.32 mm (CNePPD). CONCLUSION: Mirogabalin was generally safe, well tolerated, and effective for treatment of CNeP in this long-term study. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03901352.

Feasibility of Seated Stepping and Handshaking as a Cardiopulmonary Exercise Testing: A Pilot Study.

Cardiopulmonary function is usually assessed by cardiopulmonary exercise testing (CPX) using a cycle ergometer (CE-CPX) or a treadmill, which is difficult in patients with lower extremity motor dysfunction. A stepping and handshaking (SHS) exercise has been developed that can be performed safely and easily while sitting on a chair. This study compared peak oxygen uptake (peak V.O2) between CE-CPX and SHS-CPX in healthy adults and investigated the safety and validity of SHS-CPX. Twenty young adults (mean age 27.8 ± 4.4 years) were randomly assigned to perform CE-CPX or SHS-CPX, with the other test to follow 1-2 weeks later. The peak V.O2, respiratory exchange ratio (RER), peak heart rate, blood pressure, and test completion time were compared between CE-CPX and SHS-CPX. All subjects completed the examination and met the criteria for peak V.O2. SHS-CPX and CE-CPX showed a strong correlation with peak V.O2 (r = 0.85, p < 0.0001). The peak V.O2 (40.4 ± 11.3 mL/min/kg vs. 28.9 ± 8.0 mL/min/kg), peak heart rate (190.6 ± 8.9 bpm vs. 172.1 ± 12.6 bpm), and test completion time (1052.8 ± 143.7 s vs. 609.1 ± 96.2 s) were significantly lower in the SHS-CPX (p < 0.0001). There were no adverse events. The peak V.O2 with SHS-CPX was equivalent to about 70% of that with CE-CPX despite the exercise being performed in a sitting position, suggesting its suitability as a submaximal exercise test.

Dissonance in views between healthcare professionals and adults with a spinal cord injury with their understanding and interpretation of exercise intensity for exercise prescription.

Objectives: To evaluate the difference between healthcare professionals (HCPs) and adults with spinal cord injury (SCI) in Asia regarding knowledge and interpretation of 'exercise intensity' for aerobic exercise prescription. Methods and study design: A survey was distributed to practising HCP and adults with SCI. It was completed in participants' local language on topics related to the importance of exercise frequency, intensity, time and type; methods for monitoring and terms related to exercise intensity prescription. χ2 analysis was used to detect differences in HCP or those with SCI. Results: 121 HCP and 107 adults with an SCI ≥1 years (C1-L4) participated. Responses revealed 61% of all HCP ranked 'intensity' being most important whereas only 38% respondents from the SCI group ranked it as high importance (p=0.008). For those with SCI, 'frequency' was most important (61%) which was significantly higher than the 45% selected by HCPs (p=0.030). Of the 228 respondents on average only 34% believed that the terms, 'moderate' and 'vigorous' provided enough information for aerobic exercise intensity prescription. HCP most often used HR methods compared with the SCI group (90% vs 54%; p<0.01). Both groups frequently used the subjective measures of exercise intensity, for example, Ratings of Perceived Exertion (8%3 vs 76% for HCP and SCI), HCP also frequently used speed (81%) and SCI also frequently relied on 'the affect' or feelings while exercising (69%). Conclusions: These differences must be considered when developing clinical-practice exercise guidelines and health referral educational pathways for adults with SCI in Asia.

Effect of Three Weeks of High-Intensity, Long-Term Preoperative Rehabilitation for Esophageal Cancer Patients with Stroke Sequelae Who Were Considered Unfit for Surgery Due to Low Activity: A Case Report.

Treatment of esophageal cancer is based on tumor-node-metastasis (TNM) classification, and surgical treatment is chosen based on the patient's ability to tolerate surgery. Surgical endurance partly depends on activity status, with performance status (PS) generally used as an indicator. This report describes a 72-year-old man with lower esophageal cancer and an 8-year history of severe left hemiplegia. He had sequelae of cerebral infarction and a TNM classification of T3, N1, and M0, and was judged ineligible for surgery because his PS was grade three; he underwent preoperative rehabilitation with hospitalization for 3 weeks. He had been able to walk with a cane in the past, but once he was diagnosed with esophageal cancer, he began using a wheelchair and was dependent on assistance from his family in his daily life. Rehabilitation consisted of strength training, aerobic exercise, gait training, and activities of daily living (ADL) training for 5 h a day, according to the patient's condition. After 3 weeks of rehabilitation, his ADL ability and PS improved sufficiently for surgical indication. No complications occurred postoperatively, and he was discharged when his ADL ability was higher than that before preoperative rehabilitation. This case provides valuable information for the rehabilitation of patients with inactive esophageal cancer.

Effectiveness of a 3-Week Rehabilitation Program Combining Muscle Strengthening and Endurance Exercises Prior to Total Knee Arthroplasty: A Non-Randomized Controlled Trial.

We evaluated the effectiveness of a high-intensity preoperative resistance and endurance training program in improving physical function among patients scheduled for total knee arthroplasty. This non-randomized controlled trial included 33 knee osteoarthritis patients scheduled to undergo total knee arthroplasty at a tertiary public medical university hospital. Fourteen and nineteen patients were non-randomly assigned to intervention and control groups, respectively. All patients underwent total knee arthroplasty and a postoperative rehabilitation program. The intervention group participated in a preoperative rehabilitation program comprising high-intensity resistance and endurance training exercises to increase lower limb muscle strength and endurance capacity. The control group received only exercise instruction. The primary outcome was the 6-min walking distance, which was significantly higher in the intervention group (399 ± 59.8 m) than in the control group (348 ± 75.1 m) 3 months post-surgery. There were no significant differences between the groups 3 months post-surgery in muscle strength, visual analog scale, WOMAC-Pain, range of motion of knee flexion, and extension. A 3-week preoperative rehabilitation program combining muscle strengthening and endurance training improved endurance 3 months after total knee arthroplasty. Thus, preoperative rehabilitation is important for improving postoperative activity.

Comparative Study of Muscle Hardness during Water-Walking and Land-Walking Using Ultrasound Real-Time Tissue Elastography in Healthy Young People.

Compared with land-walking, water-walking is considered to be beneficial as a whole-body exercise because of the characteristics of water (buoyancy, viscosity, hydrostatic pressure, and water temperature). However, there are few reports on the effects of exercise in water on muscles, and there is no standard qualitative assessment method for muscle flexibility. Therefore, we used ultrasound real-time tissue elastography (RTE) to compare muscle hardness after water-walking and land-walking. Participants were 15 healthy young adult males (24.8 ± 2.3 years). The method consisted of land-walking and water-walking for 20 min on separate days. The strain ratio of the rectus femoris (RF) and medial head of gastrocnemius (MHGM) muscles were measured before and immediately after walking using RTE to evaluate muscle hardness. In water-walking, the strain ratio significantly decreased immediately after water-walking, with p < 0.01 for RF and p < 0.05 for MHGM, indicating a significant decrease in muscle hardness after water-walking. On the other hand, land-walking did not produce significant differences in RF and MHGM. Muscle hardness after aerobic exercise, as assessed by RTE, was not changed by land walking but was significantly decreased by water walking. The decrease in muscle hardness induced by water-walking was thought to be caused by the edema reduction effect produced by buoyancy and hydrostatic pressure.

Renal and Endocrine Responses to Arm Exercise in Persons with Cervical Spinal Cord Injury.

The aim of this study was to assess renal functions and endocrine responses to arm exercise in persons with cervical spinal cord injury (CSCI) under euhydrated conditions (free drinking of water), and to determine the physiological effects of exercise on renal function in these subjects. Eleven CSCI individuals (spinal lesions between C6 and C8, American Spinal Injury Association impairment scale A) and nine able-bodied (AB) persons rested for 30 min before performing 30 min arm-crank ergometer exercises at 50% of their maximum oxygen consumption, followed by 60-min of rest/recovery. Urine and blood samples were collected before and immediately after the exercise and recovery period. The CSCI patients showed no increase in plasma adrenaline and plasma renin activity compared with the AB controls, but showed similar changes in plasma aldosterone and the plasma antidiuretic hormone in response to the exercise. Creatinine clearance, osmolal clearance, free water clearance, and the fractional excretion of Na+ did not change during exercise in both groups of subjects, however free water clearance in the CSCI group was higher than in the AB group throughout the study. These findings suggested that activated plasma aldosterone without an increase in adrenaline or renin activity during exercise in CSCI individuals may reflect an adaptation to the disturbance of the sympathetic nervous system to compensate for renal function. As a result, no adverse effects of exercise on renal function in CSCI patients were observed.

Case report: Physical findings, physical therapy practice, and characteristics of disability of activities of daily living caused by obturator nerve palsy after neurotmesis.

The obturator nerve originates from the lumbar plexus and innervates sensation in the thigh and movement of the adductor muscle group of the hip. Reports on physical therapy for patients with obturator nerve injuries have been limited due to insufficient injuries, and there have been no reports on rehabilitation after neurotmesis. Furthermore, there are no reports on the status of activities of daily living (ADL) and details of physical therapy in patients with paralysis of the adductor muscle group. In this study, we reported on a patient with adductor paralysis due to obturator neurotmesis, including the clinical symptoms, characteristics of ADL impairment, and effective movement instruction. The patient is a woman in her 40's who underwent laparoscopic total hysterectomy, bilateral adnexectomy, and pelvic lymph node dissection for uterine cancer (grade-2 endometrial carcinoma). During pelvic lymph node dissection, she developed an obturator nerve injury. She underwent nerve grafting during the same surgery by the microsurgeon. Donor nerve was the ipsilateral sural nerve with a 3-cm graft length. Due to obturator nerve palsy, postoperative manual muscle test results were as follows: adductor magnus muscle, 1; pectineus muscle, 1; adductor longs muscle, 0; adductor brevis muscle, 0; and gracilis muscle, 0. On postoperative day 6, the patient could independently perform ADL; however, she was at risk of falling toward the affected side when putting on and taking off her shoes while standing on the affected leg. The patient was discharged on postoperative day 8. Through this case, we clarified the ADL impairment of a patient with adductor muscle palsy following obturator neurotmesis, and motion instruction was effective as physical therapy for this disability. This case suggests that movement instruction is important for acute rehabilitation therapy for patients with hip adductor muscle group with obturator neurotmesis.

Voluntary running-induced activation of ventral hippocampal GABAergic interneurons contributes to exercise-induced hypoalgesia in neuropathic pain model mice.

The exact mechanism of exercise-induced hypoalgesia (EIH) in exercise therapy to improve chronic pain has not been fully clarified. Recent studies have suggested the importance of the ventral hippocampus (vHPC) in inducing chronic pain. We investigated the effects of voluntary running (VR) on FosB+ cells and GABAergic interneurons (parvalbumin-positive [PV+] and somatostatin-positive [SOM+]) in the vHPC-CA1 in neuropathic pain (NPP) model mice. VR significantly improved thermal hyperalgesia in the NPP model. The number of the FosB+ cells was significantly higher in partial sciatic nerve ligation-sedentary mice than in Sham and Naive mice, whereas VR significantly suppressed the FosB+ cells in the vHPC-CA1. Furthermore, VR significantly increased the proportion of activated PV+ and SOM+ interneurons in the vHPC-CA1, and tracer experiments indicated that approximately 24% of neurons projecting from the vHPC-CA1 to the basolateral nucleus of amygdala were activated in NPP mice. These results indicate that feedforward suppression of the activated neurons via VR-induced activation of GABAergic interneurons in the vHPC-CA1 may be a mechanism to produce EIH effects, and suggested that disappearance of negative emotions such as fear and anxiety by VR may play a critical role in improving chronic pain.

A cross-sectional survey of consistent rehabilitation through long-term care insurance in Japan: a questionnaire survey.

There seems to be a lack of consistency of maintenance/community-based rehabilitation through long-term care insurance. We aimed to clarify whether consistent rehabilitation can be performed through long-term care insurance by questionnaires. Materials and Methods: This study was a cross-sectional study in a nationwide survey among rehabilitation staff and care recipients who completed disease-specific rehabilitation and required maintenance/community-based rehabilitation through long-term care insurance. Consistency of rehabilitation was compared using Fisher's exact tests. The concordance of the rehabilitation evaluation and treatment conducted under medical and long-term care insurance was assessed using the κ coefficient. Results: Six hundred questionnaires from care recipients and staff were analyzed. Of the rehabilitation staff, 264 (44%) obtained rehabilitation plans from medical institutions. There was a significant difference between the responses of "referral from the same medical corporation" and "obtaining the rehabilitation plan" by Fisher's exact test (odds ratio: 3.242; P<0.001). Most rehabilitation treatments under medical insurance comprised walking or training with parallel rods/canes [498 patients (83%)], and 454 patients (76%) received stretching and range-of-motion training for the limbs and spine for long-term care insurance. Muscle strength evaluation was the most frequently conducted under medical and long-term care insurance [383 (73%) and 487 (83%), respectively]. The concordance of the evaluation and treatment content, except for disease-specific evaluation, was low (κ coefficient≤0.6). Conclusions: The rate of provision of rehabilitation plans was low, and evaluation and treatment content under medical and long-term care insurance was inconsistent. Our results draw attention to the need for consistent rehabilitation plans between disease-specific and maintenance/community-based rehabilitation.

Quantification of catecholamine neurotransmitters released from cutaneous vasoconstrictor nerve endings in men with cervical spinal cord injury.

Control of cutaneous circulation is critically important to maintain thermoregulation, especially in individuals with cervical spinal cord injury (CSCI) who have no or less central thermoregulatory drive. However, the peripheral vasoconstrictor mechanism and capability have not been fully investigated after CSCI. Post- and presynaptic sensitivities of the cutaneous vasoconstrictor system were investigated in 8 CSCI and 7 sedentary able-bodied (AB) men using an intradermal microdialysis technique. Eight doses of norepinephrine (NE, 10-8 to 10-1 M) and five doses of tyramine (TY, 10-8, 10-5 to 10-2 M) were administered into the anterior right and left thigh, respectively. Endogenous catecholamines, noradrenaline, and dopamine, collected at the TY site, were determined by high-performance liquid chromatography with electrochemical detection. Regardless of vasoconstrictor agents, cutaneous vascular conductance decreased dose-dependently and responsiveness was similar between the groups (NE: Group P = 0.255, Dose P = 0.014; TY: Group P = 0.468, Dose P < 0.001), whereas the highest dose of each drug induced cutaneous vasodilation. Administration of TY promoted the release of noradrenaline and dopamine in both groups. Notably, the amount of noradrenaline released was similar between the groups (P = 0.819), although the concentration of dopamine was significantly greater in individuals with CSCI than in AB individuals (P = 0.004). These results suggest that both vasoconstrictor responsiveness and neural functions are maintained after CSCI, and dopamine in the skin is likely to induce cutaneous vasodilation.
