Abstract
Robot-assisted gait training is effective for walking independence in stroke rehabilitation, the hybrid assistive limb (HAL) is an example. However, gait training with HAL may not be effective for everyone, and it is not clear who is not expected to benefit. Therefore, we aimed to identify the characteristics of stroke patients who have difficulty gaining benefits from gait training with HAL. We conducted a single-institutional retrospective cohort study. The participants were 82 stroke patients who had received gait training with HAL during hospitalization. The dependent variable was the functional ambulation category (FAC) that a measure of gait independence in stroke patients, and five independent [age, National Institutes of Health Stroke Scale, Brunnstrom recovery stage (BRS), days from stroke onset, and functional independence measure total score (cognitive items)] variables were selected from previous studies and analyzed by logistic regression analysis. We evaluated the validity of logistic regression analysis by using several indicators, such as the area under the curve (AUC), and a confusion matrix. Age, days from stroke onset to HAL initiation, and BRS were identified as factors that significantly influenced walking independence through gait training with HAL. The AUC was 0.86. Furthermore, after building a confusion matrix, the calculated binary accuracy, sensitivity (recall), and specificity were 0.80, 0.80, and 0.81, respectively, indicated high accuracy. Our findings confirmed that older age, greater degree of paralysis, and delayed initiation of HAL-assisted training after stroke onset were associated with increased likelihood of walking dependence upon hospital discharge.

Abstract
BACKGROUND The ability to stand with eyes closed on a sinusoidal translational moving platform may be affected by spatial orientation owing to vestibular input information. Moreover, changes in the frequency of the moving platform may affect the sensory reweighting through somatosensory and vestibular sensations. However, it is unclear whether noisy galvanic vestibular stimulation (nGVS), which activates vestibular-related brain regions, affects the stability of individuals standing on a platform moving at different frequencies. RESEARCH QUESTION Do vestibular stimulation by nGVS and changes in the frequency of translationally moving platforms affect the standing stability of individuals? METHODS Thirty-one healthy young adult participants were provided both sham and nGVS interventions while they maintained a static standing position, with their eyes closed, on an anterior-posterior sinusoidal translation platform. The nGVS was adapted to an optimal intensity below the perceptual threshold (frequency band: 100-640 Hz), and the sham stimulus was adapted to 0 µA. The participants were randomly assessed for postural stability at 0.2, 0.6, and 1.2 Hz moving platform frequencies for 80 s each under both stimulus conditions. Postural stability was calculated as the root mean square (RMS) sway from head accelerations in the anteroposterior (AP) and mediolateral (ML) directions for 50 s between 20 and 70 s during the 80 s period, measured using an inertial sensor placed on the external occipital ridge. RESULTS nGVS significantly reduced the RMS sway of head acceleration in the AP direction compared with sham stimulation. Furthermore, nGVS significantly reduced RMS sway in the ML direction compared with sham stimulation at a 1.2 Hz moving platform oscillation. SIGNIFICANCE These findings suggest that postural adjustment by the vestibular system influences head stability on a moving platform at specific sinusoidal translation frequencies, suggesting that nGVS may reduce head sway.

Abstract
Vestibular nuclei and cerebellar function comprise vestibular neural networks that control vestibular-related responses. However, the vestibular-related responses to simultaneous stimulation of these regions are unclear. This study aimed to examine whether the combination of noisy galvanic vestibular stimulation (nGVS) and cerebellar transcranial direct current stimulation (ctDCS) using a complex transcranial electrical stimulation device alters vestibular-dominant standing stability and vestibulo-ocular reflex (VOR) function. The center of foot pressure (COP) sway and VOR of participants (28 healthy, young adults) were assessed under four conditions of transcranial electrical stimulation using nGVS and ctDCS. The COP was calculated with the participant standing on a soft-foam surface with eyes closed using a force plate to evaluate body sway. VOR measurements were collected via passive head movements and fixation on a target projected onto the front wall using a video head impulse test (vHIT). VOR gain was calculated in six directions using a semicircular canal structure based on the ratio of eye movement to head movement. The nGVS + ctDCS and nGVS + sham ctDCS conditions decreased COP sway compared to the sham nGVS + ctDCS and sham nGVS + sham ctDCS conditions. No significant differences were observed in the main effect of stimulation or the interaction of stimulation and direction on the vHIT parameters. The results of this study suggest that postural stability may be independently affected by nGVS. Our findings contribute to the basic neurological foundation for the clinical application of neurorehabilitation using transcranial electrical stimulation of the vestibular system.

Abstract
The posterior parietal cortex plays an important role in postural stability by adapting to changes in input from the visual, vestibular, and proprioceptive systems. However, little is known regarding whether transcranial electrical stimulation of the posterior parietal cortex affects reactive postural responses. This study aimed to investigate changes in physical control responses to anodal and cathodal transcranial direct current stimulation and transcranial random noise stimulation of the right posterior parietal cortex using a simultaneous inertial measurement unit. The joint movements of the lower limb of 33 healthy volunteers were measured while standing on a soft-foam surface with eyes closed during various stimulation modalities. These modalities included anodal, cathodal transcranial direct current stimulation, and sham stimulation in Experiment 1, and transcranial random noise and sham stimulations in Experiment 2. The results showed that cathodal stimulation significantly decreased the joint angular velocity in the hip rotation, ankle inversion-eversion, and abduction-adduction directions compared to anodal or sham stimulation in Experiment 1. In contrast, there were no significant differences in physical control responses with transcranial random noise stimulation coeducation in Experiment 2. These findings suggest that transcranial electrical stimulation of the right posterior parietal cortex may modulate physical control responses; however, the effect depends on the stimulus modality.

Abstract
BACKGROUND Knee pain is the main symptom of knee osteoarthritis. Walking is effective against knee pain, and some studies have shown that gait modification can also relieve this condition. However, the quality of evidence for the clinically significant effects of gait modification on knee pain has not been examined. OBJECTIVE This systematic review and meta-analysis aimed to evaluate the level of evidence for the clinically significant effects of gait modification on knee pain and determine if the effects are greater than the minimal clinically important difference (MCID). METHODS We comprehensively searched electronic databases such as MEDLINE, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and Cumulative Index to Nursing and Allied Health Literature. Intervention studies with experimental groups who received gait modification and control groups who did not were evaluated. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess the level of evidence. RESULTS Nine studies met the inclusion criteria. All were included in the systematic review and two in the meta-analysis. Results showed that gait modification have significant effects (p= 0.02), and the quality of evidence was very low. However, several studies have revealed that the effects of gait modification, when used as a foot-focused intervention, were greater than the MCID. CONCLUSIONS We concluded that there is a lack of high-quality evidence that supports the general efficacy of gait modification. Although based on low-quality evidence, when applied to the foot, it may have clinically significant effects.

Abstract
OBJECTIVE The purpose of this study was to consolidate the level of evidence for the effects of walking training with poles (pole walking; PW) on walking ability using a systematic review and meta-analysis. TYPE: Systematic review and meta-analysis. LITERATURE SURVEY Databases including PubMed, Cochrane Library, Physiotherapy Evidence Database (PEDro), Cumulative Index to Nursing and Allied Health Literature databases, and Igaku Chuo Zasshi were searched on June 20, 2021. METHODOLOGY Data from randomized controlled trials (RCTs) comparing the effects of PW with walking without poles and/or other exercise interventions in disease-specific and aging populations were collected. Data on walking speed, functional mobility, and walking endurance were collected for the meta-analyses. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated from postintervention means and standard deviations. The PEDro scale was used for assessing the risk of bias, and the Grading of Recommendations Assessment, Development, and Evaluation system was used to determine the quality of evidence. SYNTHESIS This study included 13 RCTs comprising 750 participants; of these, six RCTs were included in the meta-analysis. The results showed that moderate-quality evidence supports the positive effects of PW on walking speed in patients with Parkinson disease (walking speed: SMD = 0.42, 95% CI = 0.04-0.80). In contrast, PW did not significantly improve functional mobility in patients with Parkinson disease and walking speed in older adults. CONCLUSIONS There was moderate-quality evidence that PW improved walking speed in patients with Parkinson disease.

Abstract
Diamond step (DS) exercises are associated with multiple components of postural control and, thus, have the potential to efficiently improve balance ability. This study aimed to verify whether DS exercises contribute to improving balance ability. This study included 35 healthy young people and 29 older adults. DS exercises were performed continuously for 3 min, four times a week, for 1 month. Balance ability was assessed at baseline and after 1 and 2 months; eight items in total were examined: 30 s chair stand test, functional reach test, standing on one leg with eyes closed, time required for five rounds of DS, left-right DS, Y balance test, open-close stepping test, and finger-to-floor distance. The difficulty, achievement, and lightness/enjoyment of DS exercises were measured after the first practice and 1 month after beginning the exercises as subjective evaluations. Older adults showed improvement in seven of the eight items, with the exception being the one-legged stance with closed eyes. The subjective evaluation showed a decrease in the level of difficulty of DS exercises for older adults. DS exercises may improve balance by effectively utilizing various postural control strategies. These exercises can be effective and easy to implement, given their moderate difficulty level and self-efficacy.

Abstract
PURPOSE To determine how differences in frequency of the single-joint hybrid assistive limb (HAL-SJ) use affect the improvement of upper limb motor function and activities of daily living (ADL) in stroke patients. MATERIALS AND METHODS Subacute stroke patients were divided into the high or low frequency of HAL-SJ use groups. The two groups were matched by propensity score, and the degree of changes 30 days after initiating HAL-SJ use was compared. A logistic regression analysis was performed to examine whether frequent use would increase the number of subjects experiencing the efficacy of more than the minimal clinically important difference (MCID) of Fugl-Meyer assessment (FMA). RESULTS Twenty-five stroke patients were matched by propensity score, and nine pairs were matched. The high-frequency group showed a significantly superior increase to total FMA shoulder, elbow, forearm, and Barthel index compared with the low-frequency group. Logistic regression analysis revealed no significant associations between frequent use and MCID. CONCLUSIONS The frequency of HAL-SJ use may affect the improvement of motor function and ADL ability of the upper limb with exception of the fingers and wrist. However, the frequency of intervention was not effective enough to further increase the number of subjects with clinically meaningful changes in upper limb motor function.IMPLICATIONS FOR REHABILITATIONThe current study aimed to clarify how differences in the frequency of single-joint hybrid assistive limb (HAL-SJ) use can affect the improvement of upper-limb motor functions and ADL in subacute stroke patients.Our results implied that the frequency of HAL-SJ use may influence the recovery of upper limb function.However, even if HAL-SJ is used frequently, it does not mean that more patients will achieve clinically meaningful recovery.

Abstract
The effects of passive interpersonal light touch (PILT) on postural stability can be observed through improved postural coordination through haptic feedback from the contact provider to the contact receiver while walking. It is unclear, however, whether PILT affects the contact receiver's detailed physical responses, such as muscle activity, body sway, and joint movements. In this study, surface electromyography and an inertial measurement unit were used simultaneously to explore changes in walking speed and control responses induced by PILT. We evaluated fourteen healthy participants for their walking speed and physical responses under two walking conditions: no-touch (NT) and PILT. As a physical response during walking, we measured muscle activity (rectus femoris, semitendinosus, tibialis anterior, and soleus muscles), body sway (pelvis and neck), and joint angles (direction of hip, knee, and ankle joint movements). In PILT condition, fingertip contact force was measured while the contact provider touched the third level of the recipient's lumbar spine. In comparison with the NT condition, PILT condition increased walking speed and decreased body sway on neck position. There were significant correlations between walking speed and neck sway regarding NT and PILT change values. Passive haptic information to the contact receiver may assist in the smooth shift of the center of gravity position during gait through interpersonal postural coordination. These findings suggest that PILT may provide an efficient and stable gait.

Abstract
Aim Support for various activities of daily living is essential for maintaining the health of residents in nursing homes. Although aging people who move to nursing homes often change their skin care habits, how these changes impact aging adults' social and mental well-being remains unclear. This study aimed to evaluate the effects of facial skin care on aging residents' self-body image, self-esteem, well-being, depressive symptoms and social cognitive function by a quasi-randomized controlled pilot trial in Japanese nursing homes. Method Thirty-seven older adult women living in nursing homes took part in this quasi-randomized controlled pilot trial. Eighteen participants applied a skincare gel-cream to the face twice a day for three months, while 19 participants used no skincare products. Self-body image and psychological measures such as the Cutaneous Body Image Scale (CBIS), the Rosenberg Self-esteem Scale (RSES), Philadelphia Geriatric Center Morale Scale (PGCMS) and Geriatric Depression Scale (GDS) were used in each nursing home to evaluate the pre- and post-treatment scores. In addition, cognitive items of the Functional Independence Measure (FIM) were evaluated as social cognitive function at pre- and post-treatment. Results There was a significant different change of the Cutaneous Body Image Scale scores (p = 0.045, r = 0.34) after three months between skin care group and control group. Although there were no clear significant differences in other psychological assessments, there was a higher number of them with positive changes in the skin care group compared to the control group. Conclusion Skin care may help improve cutaneous self-body image and positive emotion in aging female residents of Japanese nursing homes.

Abstract
Background Human locomotion induces rhythmic movements of the trunk and head. Vestibular signaling is relayed to multiple regions in the brainstem and cerebellum, and plays an essential role in maintaining head stability. However, how the vestibular-cerebellar network contributes to the rhythmic locomotor pattern in humans is unclear. Transcranial alternating current stimulation (tACS) has been used to investigate the effects of the task-related network between stimulation regions in a phase-dependent manner. Here, we investigated the relationship between the vestibular system and the cerebellum during walking imagery using combined tACS over the left cerebellum and alternating current galvanic vestibular stimulation (AC-GVS). Methods In Experiment 1, we tested the effects of AC-GVS alone at around individual gait stride frequencies. In Experiment 2, we then determined the phase-specificity of combined stimulation at the gait frequency. Combined stimulation was applied at in-phase (0° phase lag) or anti-phase (180° phase lag) between the left vestibular and left cerebellar stimulation, and the sham stimulation. We evaluated the AC-GVS-induced periodic postural response during walking imagery or no-imagery using the peak oscillatory power on the angular velocity signals of the head in both experiments. In Experiment 2, we also examined the phase-locking value (PLV) between the periodic postural responses and the left AC-GVS signals to estimate entrainment of the postural response by AC-GVS. Results AC-GVS alone induced the periodic postural response in the yaw and roll axes, but no interactions with imagery walking were observed in Experiment 1 (p > 0.05). By contrast, combined in-phase stimulation increased yaw motion (0.345 ± 0.23) compared with sham (-0.044 ± 0.19) and anti-phase stimulation (-0.066 ± 0.18) during imaginary walking (in-phase vs. other conditions, imagery: p < 0.05; no-imagery: p ≥ 0.125). Furthermore, there was a positive correlation between the yaw peak power of actual locomotion and in-phase stimulation in the imagery session (imagery: p = 0.041; no-imagery: p = 0.177). Meanwhile, we found no imagery-dependent effects in roll peak power or PLV, although in-phase stimulation enhanced roll motion and PLV in Experiment 2. Conclusion These findings suggest that combined stimulation can influence vestibular-cerebellar network activity, and modulate postural control and locomotion systems in a temporally sensitive manner. This novel combined tACS/AC-GVS stimulation approach may advance development of therapeutic applications.

Abstract
BACKGROUND International guidelines recommend educational intervention to treat knee osteoarthritis. However, they do not specify the type of intervention and the effectiveness of group educational intervention for knee pain is unclear. OBJECTIVES We aimed to examine the effectiveness of group educational interventions for people over 50 years old with knee pain compared with a control group. DESIGN A systematic review and meta-analysis of randomized controlled trials (RCTs). METHOD We searched Medline, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and Cumulative Index to Nursing and Allied Health Literature and screened for RCTs involving participants over 50 years old that reported the effects of group education on knee pain. We performed meta-analyses and evaluated the methodological quality and evidence quality using the Physiotherapy Evidence Database scale and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system, respectively. RESULTS The search retrieved 1,177 studies. Seven RCTs were ultimately included, four of which were subjected to meta-analysis, showing standardized mean differences of -0.22 (95% confidence interval [CI]: -0.42 to -0.02, n = 423; I2 = 0% GRADE: low). All studies included in the meta-analysis involved exercise without individualized instruction in addition to group educational intervention. CONCLUSIONS Group education, when delivered in addition to exercises, significantly reduces knee pain in people over 50 years old.

Abstract
BACKGROUND Medial meniscal extrusion (MME) is the medial displacement of the meniscus, which extends beyond the tibial margin. Studies have shown an association between MME and knee pain and that surgical treatment can reduce the extent of MME. Here, we describe the beneficial effects of physical therapy as a feasible conservative treatment for MME. METHODS Data of 30 patients with knee osteoarthritis who underwent stretching of the semimembranosus tendon and passive range of motion (ROM) exercises twice a week for 8 weeks were retrospectively analyzed. MME was the measured distance between the medial meniscus and the line connecting the medial borders of the femur and tibia using ultrasound. Ultrasound findings of surrounding tissues, including the deep posterior bundle of the medial collateral ligament (dMCL), were recorded. Additionally, knee extension ROM was measured, and inner knee pain when walking was evaluated using a numerical rating scale. RESULTS There were significant improvements between the baseline and 8 weeks for MME in the non-weight-bearing position (3.6 ± 0.3 mm vs. 3.0 ± 0.4 mm), MME in the weight-bearing position (4.3 ± 0.4 mm vs. 3.8 ± 0.5 mm), ROM (-12.3° ± 4.1° vs. -3.1° ± 3.8°), and knee pain (7.0 ± 0.9 vs. 1.1 ± 1.4) (each p < 0.001). In almost all cases in which the knee extension ROM improved, the dMCL was bulging at the baseline; after 8 weeks, the dMCL was flattened, suggesting ligament tension on ultrasound imaging. CONCLUSION Stretching of the semimembranosus tendon and passive ROM exercises may reduce the extent of MME in patients with knee osteoarthritis. The ultrasound findings suggest that improvement in knee extension ROM may have led to the re-acquisition of MCL tension, which may have influenced MME reduction. Therefore, physical therapy may be a feasible conservative treatment for the reduction of MME.

Abstract
Objective Noisy galvanic vestibular stimulation (nGVS) is an effective method for stabilizing posture; however, little is known regarding the detailed muscle activity and joint movement in the standing posture. This study aimed to clarify the changes in the lower limb muscle activity and joint angular velocity by nGVS intervention using the simultaneous assessment method of inertial measurement units and surface electromyography (EMG). Methods Seventeen healthy participants were assessed for their physical responses under four conditions (standing on a firm surface with eyes-open/eyes-closed, and a foam surface with eyes-open/eyes-closed) without stimulation (baseline) and with stimulation (sham or nGVS). Noise stimuli were applied for 30 s at a level below the perceptual threshold. The body control response was evaluated using EMG activity and angular velocity of the lower limbs. Result Regarding the change from baseline for each parameter, there was a significant interactive effect of EMG activity in the muscle type × intervention and EMG activity and angular velocity in the condition × intervention. Post hoc analysis revealed that the angular velocity was significantly decreased in the abduction-adduction direction in the standing on a foam surface with eyes-closed condition compared to that with eyes-open in the nGVS intervention. Conclusion Our results suggest that nGVS altered physical responses in different standing postural conditions. The present study is exploratory and therefore the evidence should be investigated in future studies specifically target those muscle activities and joint motion parameters.

Abstract
[Purpose] This study investigated the association between generalized joint laxity and
knee joint movement in female university students. [Participants and Methods] The study
included 21 female university students. Generalized joint laxity was measured using the
Beighton criteria for joint hypermobility. Acceleration and angular velocities of the
tibia during knee extension were measured along three axes using a triaxial accelerometer.
Sampling data were expressed as root mean squares. The Mann–Whitney U test was used to
determine differences in the acceleration and angular velocities along each axis between
the generalized joint laxity and non-generalized joint laxity groups. Spearman’s rank
correlations were used to confirm the association between these parameters. [Results] The
rotational angular velocity was greater in the generalized joint laxity than in the
non-generalized joint laxity group, and we observed a significant correlation between
Beighton scores and the X-axis angular velocity. Furthermore, rotational angular velocity
was positively correlated with anterior–posterior acceleration and extension angular
velocity. [Conclusion] These findings suggest that rotational angular velocity of the
tibia during knee extension is associated with generalized joint laxity in female
university students.

Abstract
Objective: Combining transcranial direct current stimulation (tDCS) and repetitive gait training may be effective for gait performance recovery after stroke; however, the timing of stimulation to obtain the best outcomes remains unclear. We performed a systematic review and meta-analysis to establish evidence for changes in gait performance between online stimulation (tDCS and repetitive gait training simultaneously) and offline stimulation (gait training after tDCS). Methods: We comprehensively searched the electronic databases Medline, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and Cumulative Index to Nursing and Allied Health Literature, and included studies that combined cases of anodal tDCS with motor-related areas of the lower limbs and gait training. Nine studies fulfilled the inclusion criteria and were included in the systematic review, of which six were included in the meta-analysis. Result: The pooled effect estimate showed that anodal tDCS significantly improved the 10-m walking test (p = 0.04; I 2 = 0%) and 6-min walking test (p = 0.001; I 2 = 0%) in online stimulation compared to sham tDCS. Conclusion: Our findings suggested that simultaneous interventions may effectively improve walking ability. However, we cannot draw definitive conclusions because of the small sample size. More high-quality studies are needed on the effects of online stimulation, including various stimulation parameters.

Abstract
OBJECTIVES In post-stroke patients, shifts in the center of gravity may affect joint movement patterns of the paraplegic lower limb during walking. The impact of changes in ankle dorsiflexion angle and trailing limb angle due to slight weight-shifting is unknown. This study aimed to investigate the effect of the abovementioned parameters on gait characteristics measured by trunk acceleration. MATERIALS AND METHODS During walking, the ankle dorsiflexion angle and trailing limb angle were assessed using two-dimensional motion analysis. Shifts in the center of gravity were assessed to evaluate symmetry, regularity, and sway of trunk movements by calculating the harmonic ratio, autocorrelation coefficient, and root mean square using a wearable trunk accelerometer. RESULTS Ankle dorsiflexion angle showed a significant negative correlation with the root mean square of the anteroposterior axis (r = -0.460, p = 0.005). Trailing limb angle was significantly correlated with the autocorrelation coefficient of the vertical axis (r = 0.585, p < 0.001) and root mean square of the vertical (r = -0.579, p < 0.001), mediolateral (r = -0.474, p = 0.004), and anteroposterior axes (r = -0.548, p = 0.001). Trailing limb angle was a significant predictor (autocorrelation coefficient vertical axis, p = 0.001; root mean square vertical axis, p = 0.001; mediolateral axis, p = 0.007; anteroposterior axis, p = 0.001). CONCLUSIONS Trailing limb angle can indicate the acquisition of forward propulsion during walking; an increase in it may contribute to improvements of the regular vertical movement ability and stability of the center of gravity sway.

Abstract
Jiggling exercise is a conservative treatment for hip osteoarthritis, which involves continuous shaking of the foot and leg in small oscillations while seated. Previous studies have shown beneficial effects of jiggling exercises for outpatients with advanced- and terminal-stage hip osteoarthritis when performed for longer than 1 year, including increases in joint space width and remission of symptoms. We aimed to use the data from our own treatment to evaluate the short-term impact of intensive jiggling exercises on inpatients with hip osteoarthritis to further examine the clinical utility of this exercise. This retrospective case series study included nine patients (57 ± 12 years) with nine hip joints with advanced- or terminal-stage hip osteoarthritis who performed continuous daily jiggling exercises, beginning from day of hospitalization to 6 months post-discharge. Jiggling exercise was performed seated, using the KENKO YUSURI® automated heel vibrating machine at 3.3–5.0 Hz. The patients were also instructed against weight-bearing during hospitalization. The values of radiographic joint space width and Japanese Orthopaedic Association hip score for pain at hospital admission, discharge, and at the 6-month post-discharge checkup were evaluated. Although the hospitalization period and daily time spent performing the jiggling exercise varied in each case (27–98 days and 2–6 hours, respectively), the joint space width increased in all patients and there was an improvement in the hip pain scores in eight patients. The mean values of the minimum joint space width and hip pain scores at discharge were the highest compared to those at hospital admission and 6 months post-discharge. Our results suggest that intensive jiggling exercise for inpatients with advanced- and terminal-stage hip osteoarthritis leads to earlier improvement in joint space width and pain. Daily jiggling exercise for an adequate duration or in combination with non-weight-bearing practices may be a feasible conservative treatment for hip osteoarthritis.

Abstract
OBJECTIVES To investigate the relationship between leg skeletal muscle mass asymmetry and usual gait speed in older adults. METHODS The subjects were 139 community-dwelling older adults. The asymmetry index was calculated using the leg skeletal muscle mass index (LSMI) values of both legs. The subjects were divided into "large" and "small" asymmetry groups based on the asymmetry index. The relationship between asymmetry and gait speed was analyzed using a linear regression model. The appendicular skeletal muscle mass index and LSMI were included as adjustment variables in the analysis. RESULTS The asymmetry index and having a "large" asymmetry were independently related to gait speed, even after adjusting for covariates such as appendicular skeletal muscle mass index and LSMI. DISCUSSION Leg skeletal muscle mass asymmetry was related to gait speed independently of the appendicular skeletal muscle mass index and LSMI values. A skeletal muscle mass evaluation among older adults should include an assessment of the total skeletal muscle mass and its asymmetry.

BACKGROUND Patients with post-stroke hemiparesis have poor postural stability; nevertheless, it is unclear whether vestibular rehabilitation affects gait performance after a stroke or not. We performed a systematic review of randomized controlled trials to investigate the effects of vestibular rehabilitation on gait performance in patients with post stroke. METHODS The Medline, Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database, and Cumulative Index to Nursing and Allied Health Literature databases were comprehensively searched. All literature published from each source's earliest date to June 2019 was included. Study selection and data extraction were performed independently by paired reviewers. Outcomes of gait performance were the 10-Meter Walking Test, Timed Up and Go Test, and Dynamic Gait Index. We applied the Physiotherapy Evidence Database scale to evaluate the risk of bias and the Grading of Recommendations Assessment, Development and Evaluation system to evaluate the quality of a body of evidence. RESULTS Three studies were included, and two out of three trials showed beneficial effects of vestibular rehabilitation in post-stroke patients. Quality assessment using the Grading of Recommendations Assessment, Development and Evaluation criteria found very low-quality evidence of all included studies due to inadequate allocation concealment, low participant numbers, and lack of blinding. CONCLUSION This review found beneficial effects of vestibular rehabilitation on gait performance in patients with stroke. However, due to the very low-quality evidence of previous randomized controlled trials as assessed by the Grading of Recommendations Assessment, Development and Evaluation criteria, definitive conclusions on the effectiveness of vestibular rehabilitation cannot be made. Hence, more high-quality and large-scale randomized controlled trials of vestibular rehabilitation after stroke are needed.

Abstract
Background: The vestibular system is profoundly involved in standing postural stability. Patients with post-stroke hemiparesis have poor postural control function; nevertheless, it is unclear as to how the vestibular system affects postural control after stroke.Objectives: The purpose of this study was to quantitatively evaluate the relationship between galvanic whole-body sway responses and motor function of the hemiplegic lower extremity post-stroke.Methods: Thirty stroke patients and 49 healthy controls underwent standing body sway tests to examine postural control function during vestibular stimulation. Postural stabilization was measured using a C7-mounted accelerometer during galvanic vestibular stimulation. Postural stability was assessed during stimulation while quietly standing with eyes closed. For the stroke group, lower extremity function was measured using the Fugl-Meyer Assessment scale (FMA-LE).Results: The standing body sway test scores during stimulation were lower in the stroke group than the control group (p = .010). In the stroke group, correlation analysis demonstrated that the standing body sway response score was significantly associated with the FMA-LE (r = 0.374, p = .021).Conclusions: Motor dysfunction directly causes standing postural instability during vestibular stimulation, even though sensory information suggests normal peripheral vestibular function. Therefore, motor dysfunction of the hemiplegic lower extremity might lead to inhibition of normal standing postural stability.

Abstract
[Purpose] The aim of this study was to investigate whether the combination of integrated
volitional control functional electrical stimulation and tilt sensor functional electrical
stimulation training affected brain activation during the subacute phase following a
stroke. [Participant and Methods] The patient was a 60-year-old male with right
hemiparesis, secondary to stroke in the left thalamus. Conventional intervention was
performed for 60 minutes per day during the first two weeks of treatment (the control
condition). Functional electrical stimulation intervention, including integrated
volitional control functional electrical stimulation and tilt sensor functional electrical
stimulation training, was then performed for 60 minutes per day for two weeks (the
experimental condition). These sessions were repeated four times. Brain activity was
measured during voluntary right ankle dorsiflexion in both sessions, using functional
magnetic resonance imaging. Brain activity measurements were obtained a total of eight
times every two weeks (34, 48, 62, 76, 90, 104, 118, and 132 days following the stroke).
[Results] There was a significantly higher level of activation in the bilateral cerebellum
and the left side of the supplementary motor area in the experimental condition than in
the control condition. [Conclusion] The present study demonstrates that the combination of
integrated volitional control functional.

Abstract
[Purpose] Prevention of dementia requires early intervention against it. To ensure that early interventions are effective it is crucial to study the cognitive functions related to dementia in young adulthood. Moreover, it is needed not only to verify the cognitive function test but also to elucidate the actual brain activity and the influence of related factors on the brain activity. To investigate the factors influencing cognitive function among young adults and examine the differences in executive function by physical activity level. [Subjects and Methods] Forty healthy university students (mean age, 20.4 years) were classified into two groups by cognitive function score (HIGH and LOW), determined according to Trail Making Test performance and Stroop task processing time. We then assessed what factors were related to cognitive function by logistic regression analysis. Executive function was determined by brain blood flow using near-infrared spectroscopy during the Stroop task, and was then compared by physical activity levels (determined according to number of steps per hour). [Results] Full-scale Intelligence Quotient according to the 3rd Wechsler Adult Intelligent Scale and number of steps per hour influenced cognitive function score, with odds ratios of 1.104 and 1.012, respectively. Oxy-hemoglobin concentrations in areas related to executive function during the Stroop task were significantly higher among those in the high physical activity group than among those in the low physical activity group. [Conclusion] The study revealed that Full-scale Intelligence Quotient and a number of steps per hour are factors associated with the cognitive functions in young adulthood. In addition, activity in execution function related area was found to be significantly higher in the high physical activity group than in the low physical activity group, suggesting the importance of physical activity for enhancing young adulthood cognitive functions.

Abstract
[Purpose] The aim of the present study was to determine whether different neck and trunk
rotation speeds influence standing postural stability or frontal and temporal cortical
activity during rotation in healthy young adults. [Subjects and Methods] Twelve healthy
volunteers participated in this study. A custom turn-table operated by one of the
experimenters was placed on a platform to assess postural perturbation. Subjects were
asked to stand barefoot on the turn-table in an upright position with their feet together,
and measurements were obtained during high- and low-speed rotations. Postural stability
was tested using a force platform and a head sensor. Cerebral cortex activity was measured
using functional near-infrared spectroscopy. Brain activity, center of pressure, and head
perturbation were measured simultaneously for each subject. [Results] Significant
differences were found in the center of pressure and the head angular velocity between
high- and low-speed rotations. However, compared to baseline, oxygenated hemoglobin levels
were not significantly different during high- or low-speed rotations. [Conclusion]
Automatic postural responses to neck and trunk rotation while standing did not
significantly activate the cerebral cortex. Therefore, the response to stimuli from the
feet may be controlled by the spinal reflex rather than the cerebral cortex.

Abstract
[Purpose] The aim of this study was to evaluate the effect of active head rotation on
postural control in stroke patients during standing as compared with age-matched healthy
subjects. [Subjects and Methods] In total, 46 stroke patients and 37 age-matched healthy
subjects were recruited for the study. A stabilometer was used to assess postural
stability in participants during standing, with or without active head rotation, and with
their eyes open or closed. Subjects were asked to stand on a force plate while rotating
their head in the yaw plane at a frequency of 1.0 Hz. A metronome was used to maintain the
head rotation frequency, and the head rotation range was maintained at a total of 70°
during the postural stability examinations. [Results] The control of postural stability
during standing with active head rotation was significantly decreased in the stroke group
as compared with the healthy group with both the eyes open and closed. No significant
differences in relation to standing without head motion were observed between groups.
[Conclusion] The findings suggest that postural instability is increased in stroke
patients during active head rotation, and therefore, vestibular function in relation to
head rotation might be reduced in stroke patients.

Abstract
The effects of the endogenous opioid peptides, dynorphin (1-13), Met-enkephalin and beta-endorphin, on contraction induced by transmural stimulation of terminal bile duct preparations (terminal cavity and ampulla) and gallbladder were investigated in vitro. These peptides inhibited ampulla contraction, dose dependently. The potency order, indicated by ID50, was the same as in the guinea-pig ileum, but the absolute ID50 values in the ampulla were lower than in the ileum. In the terminal cavity, the dynorphin (1-13) ID50 was still less than in the ampulla, and beta-endorphin and Met-enkephalin did not reduce contraction by as much as 50%. In the gallbladder, the effects of these opioid peptides on contraction induced by transmural stimulation were not significant. The results suggest differences in the receptor populations of the ampulla and terminal cavity, and lack of opiate receptors (at least micro and k receptors) in the gallbladder.
