Objective : To determine whether or not the time difference index of the Timed Up and Go test (TUG) and the imagined TUG (iTUG), which reflects motor imagery capacity, has utility in predicting falls in patients with stroke. Method : A follow-up study of falls occurring over the 6-month period after discharge was performed in 47 patients with stroke. Baseline values were evaluated at discharge for subject age, sex, disease name, paralysis side, disease duration, fall history, whether a gait assistive device was used, mini-mental state examination (MMSE), TUG, and the time difference (delta time) between TUG and iTUG. A logistic regression analysis was performed using the number of falls and evaluation results, and the predictive factors for falls were extracted. Results : Thirty-three patients were followed for the entire 6-month period, and the fall rate was 48.5%. According to the results of the analysis, only delta time was a significant fall factor (p<0.01), and the cutoff value for fall prediction was 0.88%. Conclusion : Our results show that delta time could be used to identify the likelihood of a fall occurrence over the 6-month period after discharge in patients with stroke.

Objective : Little is known about the energy demands of stroke patients in the rehabilitation phase, information essential to both appropriate clinical and nutritional management. The aims of this study were to determine the resting energy expenditure (REE) of stroke patients in the rehabilitation phase, and to evaluate whether REE estimation using the Harris-Benedict equation (HBE) requires the addition of a “stress factor” to capture possible additional REE imposed by stroke. Method : We measured REE with a portable calorimeter, MetavinTR, and compared it with basal energy expenditure (BEE) calculated with HBE in 76 stroke patients admitted to a rehabilitation ward. We then analyzed its relationship with sex, stroke type, paretic side, severity of paralysis, the Functional Independence Measure (FIM) score and dysphagia. Results : Mean REE and REE/BEE (%) were 1231.3±245.7 kcal/day and 104.3±16.4%. A comparison showed no significant difference. Sex, stroke type, paretic side, severity of paralysis, FIM and dysphagia were not significantly related with REE/BEE (%). Conclusion : The REE of stroke patients was not significantly different from that predicted with HBE. This information would be useful in planning appropriate nutritional management.

Objective : The aim of this study was to assess the effects of using a motor point block with 5% phenol on spasticity and gait in patients with chronic hemiparesis. Methods : Participants were 13 patients with chronic hemiparesis after stroke, brain injury or brain tumor. We performed motor point block (MPB) with 5% phenol to the spastic muscles of the lower extremity that caused talipes varus or talipes equinus (i.e. gastrocnemius, soleus, and tibialis posterior). Before and after the MPB, we assessed modified Ashworth scale (MAS), brace wear scale (BWS) and goal attainment scale (GAS). Walking ability was measured using a 30-m walking timed test and 6-minute duration walking test. The step length, foot area during walking and body weight bearing ratio of the paretic side were measured with force plates. Results : We found significant changes in MAS of the plantar flexors (p=0.007), ankle inverters (p=0.006), walking speed (30-m walking time (p=0.046), 6-minute walking test p=0.016), foot area during the stance phase (p=0.006), and body weight bearing ratio of the paretic side (p=0.007)) and BWS (p=0.002). GAS also showed favorable appraisal of MPB by the participants. Conclusion : MPB with 5% phenol can reduce the spasticity and improve gait speed and stability.

Purpose : This study aims to measure the peak cough flow (PCF) in patients with subacute myelo-optic neuropathy (SMON) and study its relation with muscle strength, functional ability and vocal cord function. Methods : We performed a cross-sectional study in 7 patients with SMON (2 men and 5 women, mean age (SD) 81.6 (7.2) years) and in 7 age- and gender-matched patients with orthopedic problems as a control group. Their PCF, ability to walk, the Barthel Index, grip strength and maximum phonation time were assessed. Results : Mean PCF was 218.6± 66.2 L/min (110-300) for the SMON group and 267.1±76.3 L/min (170-360) for the control group (ns). The PCF was correlated with the maximum phonation time (r = 0.91 ; p<0.01), but not with grip strength, the Barthel Index or the ability to walk scale. Conclusion : The PCF in patients with SMON tended to be lower compared to the control group. Therefore, evaluating PCF is suggested to be necessary to assess the risk of pneumonia.

Objective：We aimed to determine the impact of the COVID-19 pandemic on the “body function”, “activity”, and “participation” domains of functioning as defined in the International Classification of Functioning (ICF) for individuals with spinocerebellar degeneration (SCD) and multiple system atrophy (MSA).Methods：A questionnaire survey was administered to 1,000 members of the SCD/MSA patient association in Japan between November and December 2020. Questions related to COVID-19 were extracted from the multipurpose data, and the degree of COVID-19-related effects on each life function was assessed using a 7-point scale. Results were stratified into two groups based on age, care needs based on long-term care insurance coverage, and limited opportunities for rehabilitation. The χ2 test was used to examine differences between pairs of groups regarding impacts on functioning.Results：Data from 460 participants with SCD and MSA were analyzed. Participation restriction was reported in 54％ of participants with SCD and 46％ of participants with MSA, and impairment and activity limitation in approximately 20％ of participants with both conditions resulting from the COVID-19 pandemic. Participants with low care needs reported more impairment in SCD and more participation restriction in MSA. About 24％ of subjects reported limited opportunities for rehabilitation. MSA participants with these limitations reported greater impairment.Conclusion：The COVID-19 pandemic has had a particular impact on the participation domain of functioning in participants with SCD and MSA. The domains of body function and participation were found to be affected in participants with low care needs or limited opportunities for rehabilitation.
