Effects of rehabilitation treatments jointly considered by physiatrists and rehabilitation therapists in patients with severe burn injury.

Rehabilitation treatments for patients with severe burn injury (SBI) are difficult owing to the lack of knowledge, skills, and experience among clinicians and physical and occupational therapists, resulting in serious patient disability. This study retrospectively evaluated the effectiveness of rehabilitation treatments jointly considered by physiatrists and rehabilitation therapists (Physiatrist and Registered therapist Operating rehabilitation: PROr) for patients with SBI admitted to our hospital's burn intensive care unit (BICU). Eligible patients were classified into the PROr and standard rehabilitation (SR) groups. Contents of the rehabilitation program in the BICU, the functional ambulation categories (FAC), and the Barthel index at the first rehabilitation, BICU discharge, and hospital discharge were collected. Of the 184 patients with severe burns admitted to the BICU, 29 (PROr group, n = 16; SR group, n = 13) met the eligibility criteria. The PROr group received more types of exercise interventions for a longer time than the SR group. No significant differences in the FAC and Barthel index scores at the first time of rehabilitation were found between the two groups; however, the scores of FAC and Barthel index at BICU and hospital discharges were higher in the PROr group than in the SR group. The PROr program may help in the functional improvement of patients with SBI.

Relationship between Loneliness and Mild Behavioral Impairment: Validation of the Japanese Version of the MBI Checklist and a Cross-Sectional Study.

Background: Mild behavioral impairment (MBI) and loneliness are associated with cognitive decline and an increased risk of dementia. Objective: Our aim was to examine the validity of the Japanese version of the MBI checklist (MBI-C) and investigate the relationship between loneliness and MBI. Methods: The participants in this cross-sectional study included 5 cognitively normal persons and 75 persons with mild cognitive impairment. MBI-C and the revised University of California at Los Angeles loneliness scale (LS) were used to assess MBI and loneliness, respectively. Diagnostic performance of MBI-C was examined using receiver operating characteristic analysis. The relationship between MBI-C and LS was examined using multiple linear regression in 67 subjects who were assessed with both scales, with MBI-C total or domain score as the dependent variable and LS as the independent variable, adjusted for age, gender, living situation, presence of visual and hearing impairment, and Mini-Mental State Examination score. Results: Per the Youden index, in this mostly MCI sample, the optimal MBI-C cut-off score was 5.5 with sensitivity 0.917 and specificity 0.949. In multiple linear regression analysis, LS score was detected as a significant predictor of MBI-C total scores, and MBI-C decreased motivation, affective dysregulation, and abnormal thought and perception scores. Conclusions: The caregiver-rated Japanese MBI-C has excellent diagnostic performance. Loneliness is associated with a greater MBI burden, especially in the decreased motivation, affective dysregulation, and abnormal thought and perception domains. Interventions for loneliness in older people may have the potential to improve MBI.

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.

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.

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.

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.

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.

Total Hemoglobin Mass Correlates with Peak Oxygen Consumption in Patients with Chronic Stroke.

BACKGROUND: The peak oxygen consumption (V.O2peak) and blood hemoglobin concentration [Hb] are lower in stroke patients than in age-matched healthy subjects. The ability of skeletal muscles to extract oxygen is diminished after stroke. We hypothesized that the oxygen extraction capacity of skeletal muscles in stroke patients depends on [Hb]. To test the hypothesis, we determined the relationship between V.O2peak and total hemoglobin mass (tHb-mass) in stroke patients. METHODS: The subjects were 19 stroke patients (age: 74 ± 2, mean ± SD, 10 males) and 11 age-matched normal subjects (age 76 ± 3, 6 males). Plasma volume (PV) and V.O2peak were measured on the same day. PV was measured using Evans Blue dye dilution method. Blood volume (BV) was calculated from PV and hematocrit, while tHb-mass was estimated from BV and [Hb]. Each subject underwent cardiopulmonary exercise test on a bicycle ergometer using a V.O2peak respiratory gas analyzer. RESULTS: There were no differences in age, height, and weight between the two groups. V.O2peak was lower in stroke patients than in the control. BV and tHb mass were not significantly different between the two groups, but [Hb] was significantly lower in stroke patients. In stroke patients, V.O2peak correlated significantly with tHb-mass (r = 0.497, p < 0.05), but not with BV. CONCLUSION: Our results suggested that low [Hb] seems to contribute to V.O2peak in stroke patients. The significant correlation between tHb-mass and V.O2peak suggested that treatment to improve [Hb] can potentially improve V.O2peak in stroke patients.

Effects of Combination of Functional Electric Stimulation and Robotic Leg Movement Using Dynamic Tilt Table on Walking Characteristics in Post-Stroke Patients with Spastic Hemiplegia: A Randomized Crossover-Controlled Trial.

BACKGROUND: Spastic hemiplegia causes slow and unstable walking in post-stroke patients. Dynamic tilt table with robotic leg movement (DTTRLM) is safe and effective in improving walking. Functional electric stimulation (FES) improves walking speed in post-stroke patients with spastic hemiplegia. The aim of this study was to determine the effects of combined DTTRLM + FES on walking speed compared with DTTRLM alone. METHODS: Twenty post-stroke patients were randomly assigned to receive either a single session of stepping + FES treatment or a single session of stepping alone treatment. After a one-week washout period, the same two groups underwent a single session of the other treatment, and the same measurements were taken. We measured walking speed, cadence, and the number of steps in a 10 m walking test (10MWT) and assessed Modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA), and range of motion (ROM) before and after the intervention. RESULTS: Stepping + FES significantly improved walking speed, number of steps, and ankle inversion ROM, compared with stepping alone. Adverse events were not observed in any subject. CONCLUSIONS: Robotic stepping therapy combined with FES significantly improved 10 m walking speed (10MWS) compared with stepping only in patients with post-stroke and spastic hemiplegia. Further studies are needed to determine the long-term effects of the combination treatment.

Surface electromyographic activity of the erector spinae and multifidus during arm- and leg-ergometer exercises in young healthy men.

Objectives: Ergometer exercise was considered a new loading method that can be used for participants who are unable to assume the core strengthening exercise posture commonly used to strengthen the erector spinae and multifidus. This study aimed to investigate with healthy participants whether arm and leg ergometers could be used for core strengthening exercises and whether different exercise sites would affect the results. Methods: The study was conducted with 15 healthy adult male participants aged 20-35 years. The intervention consisted of arm- and leg-ergometer exercises performed by the participants. The exercise protocol consisted of three 1-min sessions (rest, 50W, and 100 W), which were measured consecutively. Surface electromyography (sEMG) was measured during the sessions. Maximal voluntary contraction (MVC) of the erector spinae and multifidus was also measured, during which sEMG was measured. The sEMG during ergometer exercise was calculated as a percentage of the MVC (calculated as % MVC). The root mean square (RMS) was recorded from the sEMG activity. Muscle activity of the erector spinae and multifidus was compared between ergometer exercises and between intensity levels. Heart rate (HR) was recorded by electrocardiogram. Results: In the arm-ergometer exercise, the % MVC values of the erector spinae were 6.3 ± 3.1, 10.9 ± 5.4, and 16.9 ± 8.3% at rest, 50 W, and 100 W conditions, respectively. The multifidus was 4.6 ± 2.9, 9.2 ± 5.6, and 12.6 ± 7.6% at rest, 50 W, and 100 W conditions, respectively. The respective % MVC values during the leg-ergometer exercise were 3.8 ± 1.7, 7.2 ± 3.8, and 10.4 ± 4.0% at rest, 50 W, and 100 W conditions, respectively. Leg-ergometer exercises were 2.6 ± 2.1, 6.9 ± 5.7, and 10.3 ± 6.8% at rest, 50 W, and 100 W conditions, respectively. The activities of the two muscles increased at comparable levels with increased workload in both types of exercises (p < 0.01, each). HR increased with the increased workload and the increase was larger during arm-than leg-ergometer exercises. Conclusion: These results demonstrate that both arm- and leg-ergometer exercises are potentially alternative methods for erector spinae and multifidus training for healthy participants. Further research is needed to target elderly.

Rehabilitation in the long-term care insurance domain: a scoping review.

PURPOSE: Since the enactment of the long-term care insurance (LTCI) act in 2000, the number of LTCI users has increased annually. However, evidence regarding what is being carried out as rehabilitation treatment under LTCI is lacking. In this study, a scoping review was performed to bridge this knowledge gap. METHODS: Articles related to rehabilitation in connection with LTCI published between April 2000 and November 2020 were searched for in PubMed, CINAHL, CENTRAL (Cochrane Central Register of Controlled Trials), Ichushi Web Ver.5, and CiNii and randomized controlled trials (RCTs) of rehabilitation provided under LTCI were examined. RESULTS: Of the 15,572 publications identified, 15 RCTs, including rehabilitation treatment by physiatrists and therapists, met the eligibility criteria of our review and were included. The rehabilitation trials in the 15 RCTs varied and included balance training, exercise therapy, cognitive tasks, and activities such as singing and dancing. The results allowed us to focus on three categories: fall prevention, dementia, and theory and tools interventions related to occupational therapy practice. CONCLUSION: The focal points of attention in the rehabilitation treatment of LTCI were identified. However, the physical function, quality of life, and activities of daily living (ADL) of those who "need support" vary from person to person. Therefore, the consolidation of evidence on rehabilitation treatment of LTCI must be continued.

Standing and supine positions are better than sitting in improving rightward deviation in right-hemispheric stroke patients with unilateral spatial neglect: A randomized trial.

TRIAL DESIGN: How body position affects unilateral spatial neglect (USN) is unclear. This cluster randomized trial aimed to examine the effects of different positions (supine, sitting, and standing) on USN in stroke patients. METHODS: Twenty stroke patients (hemorrhage [n = 11], infarction [n = 9]) who were right-handed, had left hemiplegia due to right hemisphere damage that occurred within the last 2 years, and were in a state of arousal with a Glasgow Coma Scale score of 15 were included in the study. Table-top pen-and-pencil tests for USN (Bells Test, Line Bisection, Scene Copy, and Star Cancellation) were randomly conducted in the supine, sitting, and standing positions. RESULTS: The mean values in each test were significantly smaller in the supine position than were those in the sitting position (P = .015, .047, .015, and <.001), and those in the standing position were significantly smaller than those in the sitting position (P = .007, <.001, =.006, and < .001). The results of the 4 tests in the standing position were similar to those in the supine position. CONCLUSIONS: Body position affects USN in stroke patients and that the standing and supine positions improve USN better than the sitting position. Some possible mechanisms are: muscle contractions in the lower limbs and the trunk could have affected results in the standing position, and reduction in gravitational stimulation in the supine position could have played a role.

Effect of 3-week preoperative rehabilitation on pain and daily physical activities in patients with severe osteoarthritis undergoing total knee arthroplasty.

Background: We hypothesized that 3 weeks of preoperative rehabilitation could improve postoperative pain in patients undergoing total knee arthroplasty (TKA). Aim: This study aimed to evaluate the effects of 3 weeks of preoperative rehabilitation on postoperative pain after TKA. Methods: This prospective cohort study included 29 subjects (41 knees) divided into two groups: the preoperative rehabilitation group included 14 subjects (20 knees) and the control group included 15 subjects (21 knees). All subjects were scheduled for unilateral or bilateral TKA. The preoperative rehabilitation group completed a 90-min rehabilitation program 3 days per week for 3 weeks before their TKA. The rehabilitation included body weight exercise, resistance exercise, and cycle ergometer exercise. The control group did not undergo any rehabilitation prior to TKA. We assessed the patients using Western Ontario and McMaster Universities' Osteoarthritis Index (WOMAC) and recorded their physical activity of walking, standing, sitting, and lying down at study entry and/or before TKA and 1 month after TKA. Results: The WOMAC total and WOMAC pain scores were significantly lower after 3-weeks of rehabilitation, but before TKA and 1 month after surgery were significantly lower in the preoperative rehabilitation group than in the control group. The time spent walking, standing, sitting, and lying down for 12 h did not change after TKA in the preoperative rehabilitation group. In contrast, in the control group, the time spent in walking and standing positions decreased and the time in the sitting position increased after TKA (p < 0.05). Conclusion: We found that 3-week preoperative training reduced knee pain and helped maintain physical activity after surgery in patients with severe osteoarthritis who underwent TKA.
