Robot-assisted rehabilitation for patients with stroke is promising. However, it is unclear whether additional balance training using a balance-focused robot combined with conventional rehabilitation ...programs supplements the balance function in patients with stroke. The purpose of this study was to compare the effects of Balance Exercise Assist Robot (BEAR) training combined with conventional inpatient rehabilitation training to those of conventional inpatient rehabilitation only in patients with hemiparetic stroke. We also aimed to determine whether BEAR training was superior to intensive balance training.
This assessor-blinded randomized controlled trial included 60 patients with first-ever hemiparetic stroke, admitted to rehabilitation wards between December 2016 and February 2019. Patients were randomly assigned to one of three groups, robotic balance training and conventional inpatient rehabilitation (BEAR group), intensive balance training and conventional inpatient rehabilitation (IBT group), or conventional inpatient rehabilitation-only (CR group). The intervention duration was 2 weeks, with assessments conducted pre- and post-intervention, and at 2 weeks follow-up. The primary outcome measure was a change in the Mini-Balance Evaluation Systems Test (Mini-BESTest) score from baseline.
In total, 57 patients completed the intervention, and 48 patients were evaluated at the follow-up. Significant improvements in Mini-BESTest score were observed in the BEAR and IBT groups compared with in the CR group post-intervention and after the 2-week follow-up period (P < 0.05).
The addition of balance exercises using the BEAR alongside conventional inpatient rehabilitation improved balance in patients with subacute stroke.

Aim
To elucidate the incidences and circumstances of falls and fall‐related injuries, and to explore the physical characteristics of community‐dwelling ambulatory stroke survivors who experienced ...falls.
Methods
A total of 144 community‐dwelling ambulatory survivors of hemiparetic stroke (mean age 68.0 years SD 10.4 years) who were undergoing rehabilitation in an adult daycare center participated in this prospective study. The mean duration from stroke onset was 5.21 years (SD 3.15 years). The occurrence of falls was collected for 1 year with a fall diary. The incidence rates of falls and fall‐related injuries, and the detailed circumstances of falls were descriptively analyzed. The characteristics of fallers were explored by comparing background information, motor impairments and results of physical function tests, including the 10‐m walk test, Timed Up and Go test and five‐times‐sit‐to‐stand test, between fallers and non‐fallers.
Results
The incidence rates of falls and fall‐related fractures were 0.88 per person‐year and 2.8 per 100 person‐years, respectively. Falls occurred more frequently during daytime and in winter. Falls were caused most often by losing balance while walking indoors, especially on the way to the toilet. After falling, 34.1% of individuals who fell could not stand up by themselves. The time of the five‐times‐sit‐to‐stand test was significantly longer in fallers than in non‐fallers (P < 0.05).
Conclusions
The incidence rate of falls was high among community‐dwelling ambulatory survivors of hemiparetic stroke. Appropriate approaches, including mastering the skills to cope with falling, are required, especially for individuals with reduced lower limb muscle strength. Geriatr Gerontol Int 2019; 19: 240–244.
As humans, we constantly change our movement strategies to adapt to changes in physical functions and the external environment. We have to walk very slowly in situations with a high risk of falling, ...such as walking on slippery ice, carrying an overflowing cup of water, or muscle weakness owing to aging or motor deficit. However, previous studies have shown that a normal gait pattern at low speeds results in reduced efficiency and stability in comparison with those at a normal speed. Another possible strategy is to change the gait pattern from normal to step-to gait, in which the other foot is aligned with the first swing foot. However, the efficiency and stability of the step-to gait pattern at low speeds have not been investigated yet. Therefore, in this study, we compared the efficiency and stability of the normal and step-to gait patterns at intermediate, low, and very low speeds. Eleven healthy participants were asked to walk with a normal gait and step-to gait on a treadmill at five different speeds (i.e., 10, 20, 30, 40, and 60 m/min), ranging from very low to normal walking speed. The efficiency parameters (percent recovery and walk ratio) and stability parameters (center of mass lateral displacement) were analyzed from the motion capture data and then compared for the two gait patterns. The results suggested that step-to gait had a more efficient gait pattern at very low speeds of 10-30 m/min, with a larger percent recovery, and was more stable at 10-60 m/min in comparison with a normal gait. However, the efficiency of the normal gait was better than that of the step-to gait pattern at 60 m/min. Therefore, step-to gait is effective in improving gait efficiency and stability when faced with situations that force us to walk slowly or hinder quick walking because of muscle weakness owing to aging or motor deficit along with a high risk of falling.
The aim of this study was to compare the clinical applicability of the Mini-Balance Evaluation Systems Test and the Berg Balance Scale for measuring balance in inpatients with subacute stroke.
This ...was a prospective observational study which included 58 consecutive patients admitted to a convalescent rehabilitation hospital with a first-ever stroke and who met the inclusion/exclusion criteria. The Mini-Balance Evaluation Systems Test and the Berg Balance Scale were used to assess patient balance at admission and discharge. The ceiling and floor effects and responsiveness of each balance score were examined. In addition, receiver operating characteristic analysis based on each balance score at admission was used to examine its discriminative power to predict ambulatory independence and falls during hospitalization.
The mean (standard deviation) change between admission and discharge for each balance scale was 4.4 (4.7) for the Mini-Balance Evaluation Systems Test and 8.3 (10.0) for the Berg Balance Scale, with standard response means, a measure of responsiveness of 0.9 (large) and 0.8 (medium), respectively. Each balance score at admission almost equally predicted gait independence and fallers during hospitalization. On the contrary, only the distribution of scores on the Berg Balance Scale at discharge showed a ceiling effect, with 25 patients (43%) obtaining a perfect score.
The Mini-Balance Evaluation Systems Test may be useful as a balance measure for inpatients with subacute stroke because it is less susceptible to ceiling effects and more responsive than the Berg Balance Scale.
We present the case of a 42-year-old man with subacute stroke who developed remarkable fear of falling and eventually recovered with an approach based on cognitive behavioral therapy (CBT). The ...CBT-based approach was implemented after the patient developed significant fear of falling with exacerbated obsessive-compulsive symptoms appeared immediately after a fall. The patient's anxiety decreased over time, and his ability to perform these tasks and activities of daily living improved accordingly. After 6 weeks of intervention, his anxiety toward gait and stairs almost disappeared; additionally, he achieved modified independence for gait and supervision for stairs and was discharged home successfully. These findings in the present case suggest the effectiveness of an evaluation and interventional approach based on CBT for stroke patients with a severe fear of falling.
Falls are one of the most common complications of a stroke. This study aimed to clarify the discrepancy between the perceived fall risk of hospitalized patients with stroke and the clinical judgment ...of physical therapists and to examine the changes in discrepancy during hospitalization.
Retrospective cohort study.
This study included 426 patients with stroke admitted to a Japanese convalescent rehabilitation hospital between January 2019 and December 2020.
The Falls Efficacy Scale-International was used to assess both patients' and physical therapists' perception of fall risk. The difference in Falls Efficacy Scale-International scores assessed by patients and physical therapists was defined as the discrepancy in fall risk, and its association with the incidence of falls during hospitalization was investigated.
Patients had a lower perception of fall risk than physical therapists at admission (
< 0.001), and this trend continued at discharge (
< 0.001). The discrepancy in fall risk perception was reduced at discharge for non-fallers and single fallers (
< 0.001), whereas the difference remained in multiple fallers.
Unlike physical therapists, patients underestimated their fall risk, especially patients who experienced multiple falls. These results may be useful for planning measures to prevent falls during hospitalization.
Patient motivation is an important determinant of rehabilitation outcomes. Differences in patients' and clinicians' perceptions of motivational factors can potentially hinder patient-centered care. ...Therefore, we aimed to compare patients' and clinicians' perceptions of the most important factors in motivating patients for rehabilitation.
This multicenter explanatory survey research was conducted from January to March 2022. In 13 hospitals with an intensive inpatient rehabilitation ward, 479 patients with neurological or orthopedic disorders undergoing inpatient rehabilitation and 401 clinicians, including physicians, physical therapists, occupational therapists, and speech-language-hearing therapists, were purposively selected using inclusion criteria. The participants were asked to choose the most important factor motivating patients for rehabilitation from a list of potential motivational factors.
Here we show that realization of recovery, goal setting, and practice related to the patient's experience and lifestyle are the three factors most frequently selected as most important by patients and clinicians. Only five factors are rated as most important by 5% of clinicians, whereas nine factors are selected by 5% of patients. Of these nine motivational factors, medical information (p < 0.001; phi = -0.14; 95% confidence interval = -0.20 to -0.07) and control of task difficulty (p = 0.011; phi = -0.09; 95% confidence interval = -0.16 to -0.02) are selected by a significantly higher proportion of patients than clinicians.
These results suggest that when determining motivational strategies, rehabilitation clinicians should consider individual patient preferences in addition to using the core motivational factors supported by both parties.
To examine the reliability and validity of the public transportation use assessment form (PTAF), which was developed for assessing the performance of tasks during public transportation use.
Fifty ...consecutive patients admitted after a stroke to a convalescent rehabilitation hospital and received field-based practice for public transportation use were enrolled. A physical therapist (PT) and an occupational therapist (OT) independently evaluated actual participant performance using the PTAF. Its internal consistency, inter-rater reliability, and construct validity were examined against other clinical measures related to the ability to use public transportation.
Cronbach's coefficient alpha for the internal consistency for overall PTAF was 0.84 and 0.88 for PTs and OTs, respectively. Cohen's weighted κ coefficient for the inter-rater reliability for each item ranged from 0.61 to 0.83. Intraclass correlation coefficients for the inter-rater reliability for the mean scores of the items comprising the PTAF were 0.90 for all 14 items, 0.76 for items required for train use only, and 0.88 for items required for bus use only. The correlation coefficients for the construct validity between PTAF and clinical measures ranged from 0.38 to 0.59 (p < 0.05).
The PTAF showed sufficient internal consistency, intra-rater reliability, and construct validity.
Implications for rehabilitation
This study illustrated the inter-rater reliability of the public transportation use assessment form (PTAF), indicating that the PTAF can be used for reliable assessment independent of the rater.
The PTAF showed good internal consistency, indicating that each item in the PTAF consistently assessed the ability of patients with stroke to use public transportation.
The PTAF correlated with assessment tools such as walking ability, balance, motor paralysis, intelligence, and activities of daily living, indicating that it reflects the functions and abilities necessary to use public transportation.
To develop a new assessment form that is assessed by therapists for the performance of public transportation use for stroke survivors through content validation.
The items for the tentative ...assessment form were selected using hierarchical clustering analysis on previous records of 76 field-based training sessions for public transportation use for stroke survivors. After the modification of the tentative form based on 6 months of clinical use, the final form was developed through content validation using the Delphi method by 71 therapists who had been working at the hospital for more than 2 years and had experience with training for public transportation use.
The Public Transportation use Assessment Form (PTAF) for stroke was successfully developed through three validation processes. It consists of four categories (plan for going out, mobility, using trains, and using buses) including 15 items that cover various tasks of public transportation use. The scoring for each was as follows: 3, independent; 2, requires supervision of verbal assistance; 1, requires assistance; and N, not applicable.
The PTAF, developed through content validation, could assess the ability of public transportation use, and identify specific problems for each stroke survivor in clinical setting.
IMPLICATIONS FOR REHABILITATION
We developed the Public Transportation use Assessment Form (PTAF) to assess the ability of stroke survivors to use public transportation.
The PTAF could identify specific problems related to public transportation use for stroke survivors and aid in planning rehabilitation programs based on the results.
The PTAF could share information about which task need support in public transportation use and could augment the hospital discharge plan.
Although the standard falls prevention strategy is to identify and respond to patients with high-risk conditions, it remains unclear whether falls in patients with high fall risk account for most ...observed falls. In this study, fall risk and number of falls were calculated based on patients' motor and cognitive abilities, and the relationship between the two was examined.
We conducted a retrospective cohort study.
We included 2518 consecutive patients with stroke who were admitted to a rehabilitation hospital.
Data on falls during hospitalization and biweekly assessed Functional Independence Measure scores were retrieved from the medical records. The average Functional Independence Measure scores for the motor and cognitive items were obtained and categorized as complete dependence, modified dependence, and independence. The fall rate (falls/1000 person-days) and number of observed falls in each combined condition were investigated.
Modified dependence on motor ability and complete dependence on cognitive ability had the highest risk of falls, with a fall rate of 10.8/1000 person-days and 51 fall observations, which accounted for 4.3% of all falls. Independent motor and cognitive ability had the lowest risk of falls, a fall rate of 2.6/1000 person-days and 146 observed falls, accounting for 12.4% of all falls, which was 2.8 times higher than the number of falls observed in the highest risk of falls condition.
The combined motor-cognitive ability with the highest risk of falls in stroke inpatients did not have the highest number of observed falls. Rather, the combined motor-cognitive ability with the lowest risk of falls tended to have a high number of observed falls. A different strategy is needed to reduce the total number of falls.
