RESUMO
Objectives: Occupational therapy (OT) studies of delirium have attempted to test the effectiveness of interventions to reduce the incidence and duration of delirium. Although some cognitive stimulation appears to be important, appropriate approaches to delirium characterized by cognitive dysfunction remain unclear. This study aimed to determine the incidence and duration of delirium in postoperative cardiovascular surgery patients at the initial time of OT to identify characteristics of patient demographics and cognitive function according to the presence or absence of delirium. Methods: This retrospective study included patients judged to have delirium by the Confusion Assessment Method at the first postoperative OT session (after extubation) in the intensive care unit (ICU). Patient data included age, sex, days until extubation, type of hospitalization, outcome at discharge, Sequential Organ Failure Assessment score and Glasgow Coma Scale (GCS) score at the first OT session, presence or absence of delirium, duration of delirium, and Mini-Mental State Examination-Japanese (MMSE-J) score. The Mann-Whitney U test was used to test differences between the delirium and the non-delirium groups, and a binomial generalized linear model (logistic regression model) with Bayesian estimation was adopted to investigate factors characterizing delirium. Results: A Bayesian logistic regression model with delirium as the dependent variable and "days until extubation" and "spatial orientation" as adjustment variables suggested that "spatial orientation" was a significant factor in delirium. Conclusions: For ICU patients with delirium, the provision of information tailored toward spatial orientation during the first day of OT may improve delirium.
RESUMO
BACKGROUND: Identifying accurate prognostic factors is crucial for postoperative management of early gastric cancer (EGC) patients. Skeletal muscle quality (SMQ), defined by muscle density on computed tomography (CT) images, has been proposed as a novel prognostic factor. This study compared the prognostic significance of SMQ changes with the well-established factor of body weight (BW) loss in the postoperative EGC setting. METHODS: This single-center retrospective study included 297 postoperative EGC patients (median age 69 years, 68.4% male) who had preoperative and 1-year-postoperative gastrectomy CT images. SMQ was defined as the modified intramuscular adipose tissue content (mIMAC = skeletal muscle density-subcutaneous fat density on CT images) and the change as ΔmIMAC. Log-rank test, Kaplan-Meier survival, and Cox proportional hazards regression analyses were used to assess the associations between prognosis and either ΔmIMAC or BW change (ΔBW). Prognosis prediction by ΔmIMAC and ΔBW was compared by using the area under the curve (AUC) of the receiver operating characteristic curve. RESULTS: ΔmIMAC was significantly associated with prognosis (log-rank test; P = 0.037), but ΔBW was not (P = 0.243). Prognosis was significantly poorer in the severely decreased mIMAC group than in the preserved group (multivariate Cox proportional hazards regression analysis; P = 0.030) but was unaffected by BW changes (P = 0.697). The AUC indicated a higher prognostic value for ΔmIMAC than ΔBW (ΔmIMAC: AUC = 0.697, ΔBW: AUC = 0.542). CONCLUSIONS: One-year post-gastrectomy SMQ changes may be better prognostic EGC predictors than BW changes.
RESUMO
BACKGROUND AND PURPOSE: Sarcopenia is known to be associated with poor outcomes after arthroplasty; however, no study has reported the relationship between sarcopenia and postoperative walking independence. This study aimed to determine the impact of sarcopenia risk screening using the SARC-CalF questionnaire and calf circumference on the time to walk independently after total hip or knee arthroplasty in older patients. METHODS: We included 599 nonobese patients aged 65 years and older who underwent unilateral and primary total hip or knee arthroplasty. Preoperative sarcopenia risk was assessed using the SARC-CalF or calf circumference. The outcome of this study was the time to independent walking after surgery; it was calculated as the number of days from the date of surgery to the date when the patient was able to walk independently. The association between preoperative sarcopenia risk and time to independent walking after surgery was analyzed using Kaplan-Meier curves and Cox proportional hazards models. RESULTS: Among the 599 patients undergoing total joint arthroplasty, 175 (29.2%) were determined to be at risk of sarcopenia using SARC-CalF and 193 (32.2%) using calf circumference. The Kaplan-Meier curve showed that sarcopenia risk assessed by SARC-CalF or calf circumference was associated with a prolonged time to independent walking in patients undergoing hip arthroplasty (log-rank test, P < .001 and P < .001, respectively). In patients undergoing hip arthroplasty, the Cox proportional hazards model showed that SARC-CalF score of 11 points and greater or a calf circumference less than the cutoff was a risk factor for delayed time to independent walking (hazard ratios: 0.55 and 0.57, P < .001 and P = .001, respectively). There was no association between preoperative sarcopenia risk and postoperative time to independent walking in patients who underwent knee arthroplasty. CONCLUSIONS: Sarcopenia screening tools, such as SARC-CalF or calf circumference, should be useful for planning postoperative rehabilitation in older adults scheduled for hip arthroplasty. However, the accuracy of SARC-CalF or calf circumference measurement in patients scheduled for knee arthroplasty may be low.

BACKGROUND: Understanding the degree of motor paralysis in stroke patients is important for assessing the severity of functional impairment and predicting functional prognosis. Fugl-MeyerAssessment for the lower extremities (FMA-LE)is a commonly used measure with high reliability and validity, but there is no official translated Japanese version of FMA-LE. OBJECTIVES: This study aimed to develop Japanese FMA-LE and verify its reliability and validity in patients with acute stroke. METHODS: The Japanese FMA-LE was developed following a standardized translation process. The reliability and validity were evaluated in 50 stroke patients at an acute care hospital. Validity was examined by determining the correlation between FMA-LEand Brunnstrom Recovery Stage (BRS), as well as Short Physical Performance Battery (SPPB). Intra-raterand inter-raterrelative reliabilities were evaluated by calculating intra-classcorrelation coefficients (ICCs). Absolute reliability was assessed by determining the standard error of the measurement and minimum detectible change (MDC). Systematic error was also assessed. RESULTS: FMA-LEtotal score was high correlated with BRS (ρ = 0.73,p < .01) and moderately correlated with SPPB (ρ = 0.69,p < .01). For intra-raterreliability, ICC was 0.98 (p < .01), only fixed systematic error was observed (p < .01), and MDC of the FMA-LEtotal score was 1.24. For inter-raterreliability, ICC was 0.98 (p < .01), no systematic error was observed, and MDC of the FMA-LEtotal score was 3.23. CONCLUSIONS: The Japanese FMA-LE was reliable, valid, and useful for evaluating lower extremity function of acute stroke patients.

BACKGROUND: Rotator cuff tears (RCTs) are often associated with severe shoulder pain. Non-steroidal anti-inflammatory drugs, not recommended for long-term use, do not effectively manage RCT-induced pain, resulting in reduced quality of life. To improve management, a better understanding of the fundamental properties of RCT pain is needed. Here, we aimed to compare the expression levels of nerve growth factor (NGF) and cyclooxygenase-2 (COX-2) mRNA in the synovial tissues of patients with RCT-induced pain and patients with non-painful recurrent shoulder dislocation (RSD). METHODS: The study included 32 patients with RCT who underwent arthroscopic rotator cuff repair and 28 patients with non-painful RSD who underwent arthroscopic Bankart repair. Synovial tissue samples were harvested from subacromial bursa and rotator interval of RCT patients and from the rotator interval of RSD patients. Samples were analyzed quantitatively expression levels for NGF and COX2 mRNA and NGF protein. RESULTS: NGF mRNA and protein levels were significantly higher in the rotator interval of RCT patients than in the rotator interval of RSD patients (p = 0.0017, p = 0.012, respectively), while COX2 mRNA levels did not differ significantly between the two patient groups. In RCT patients, COX2 mRNA was more highly expressed in the rotator interval than in the subacromial bursa (p = 0.038), whereas the mRNA and protein levels of NGF did not differ between the two tissues. The expression of NGF mRNA in the synovium of the rotator interval was significantly correlated with the numeric rating scale of pain (ρ = 0.38, p = 0.004). CONCLUSION: NGF mRNA and protein levels were elevated in patients with painful RCT compared with those in patients with non-painful RSD, whereas COX-2 levels were comparable in the two patient groups. These findings provide insights into novel potential strategies for clinical management of RCT.

BACKGROUND: One of the mechanisms of the efficacy of extracorporeal shock wave therapy (ESWT) for impaired muscle coordination of limbs is the destruction of Acetylcholine receptors (AChRs) at neuromuscular junction. The highly increased density of AChRs can change the acoustic impedance, and this change of the acoustic impedance can be the reason that radial shock wave (rESW) destroy AChRs selectively. However, the relationship between applied energy of rESWs and the therapeutic efficacy remains unclear, although some studies compared the clinical efficacy of rESWT between high- and low-energy applications. This study aimed to compare the CMAP change among different energy and pulses of rESW application. METHODS: Male Sprauger-Dawley rats were used. A device that generates radial shock waves pneumatically, was used to apply the following six patterns of radial extracorporeal shockwaves in different energy flux densities and pulses to the right calf of each rat: 1, 8000 pulses at 0.045 mJ/mm2; 2, 4000 pulses at 0.09 mJ/mm2; 3, 2000 pulses at 0.18 mJ/mm2; 4, 4000 pulses at 0.045 mJ/mm2; 5, 2000 pulses at 0.09 mJ/mm2; 6, 1000 pulses at 0.18 mJ/mm2. Left calf muscles were considered controls. RESULTS: There was a significant reduction in CMAP amplitude between control and rESW-exposed muscles in the group applied 4000 pulses with EFD at 0.09 mJ/mm2 and the group applied 2000 pulses with EFD at 0.18 mJ/mm2. However, the group applied 8000 pulses with EFD at 0.045 mJ/mm2 and all groups which was exposed to total 180 mJ rESW application did not show a significantly decreased CMAP amplitude compared with the untreated side. CONCLUSIONS: Total energy and energy flux density correlate with a decrease in CMAP amplitude by rESW application. These findings could be availed by clinicians in actual clinical setting for the proper application of rESW.

OBJECTIVES: There are few scales that reflect the function of the stroke-affected arm as it relates to the performance of daily activities while also indicating the difficulty of scale items. In this study, we developed the Activities Specific Upper-extremity Hemiparesis Scale (ASUHS) to evaluate daily activities performable by the affected arm after stroke. We also clarified the validity, reliability, and item difficulty of the scale. METHODS: The participants were 145 patients with stroke who were consecutively admitted to a convalescent rehabilitation ward. The unidimensionality of ASUHS was assessed by principal component analysis. Analyses of item discrimination and content validity were conducted to assess the overall validity. Reliability was evaluated by assessing internal consistency and inter-rater reliability. Item difficulties were determined by Rasch analysis. RESULTS: Unidimensionality, high discrimination, and good content validity were shown for all items. ASUHS consists of a dominant hand scale and non-dominant hand scale. Both scales showed good internal consistency (Cronbach's α coefficient = 0.99) and substantial inter-rater reliability (Cohen's Kappa coefficient = 0.74 and 0.75, respectively). Item difficulty was determined as being in the range -8.71 to +5.18 logit. CONCLUSIONS: This study suggested good validity and reliability of ASUHS. Furthermore, because the item difficulties of daily activities performed by the affected arm were clarified, therapists can use ASUHS to identify the process that should be the next focus for training. Consequently, therapists may be able to train patients in daily activities that match the affected arm's ability step by step rather than determining training activities empirically.
RESUMO
Objective To describe the clinical features and clinical course of individuals diagnosed with asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or mild coronavirus disease (COVID)-19. Patients The study participants consisted of 7 crewmembers of the passenger cruise-liner, Diamond Princess, who were admitted to our hospital after becoming infected with SARS-CoV-2 aboard the ship. Methods The data on patient background and biochemical test results were obtained from the patients' medical records. All patients had a chest X-ray, and a throat swab and sputum samples were sent for culture on admission. Results The median age of the 7 patients, of whom 4 were male and 3 were female, was 39 years (range: 23-47 years). On admission, none of them had fever, but 4 (57%) had a cough. None of them showed any signs of organ damage on laboratory testing. Chest X-ray showed pneumonia in one individual, which resolved spontaneously, while the other 6 had normal chest X-ray findings. Culture of throat swabs and sputum samples revealed that 4 patients (57%) had bacterial upper respiratory infections (Haemophilus influenzae, Klebsiella pneumoniae, and Staphylococcus aureus). The period from a positive polymerase chain reaction (PCR) test to negative conversion ranged from 5 to 13 days, with a median of 8 days. Conclusion Healthy young adults without risk factors who acquire SARS-CoV-2 infection may have an asymptomatic infection or may experience mild COVID-19. In addition to obesity, an older age, underlying illness, and being overweight can lead to a risk of exacerbation; thus, hospital management for such individuals may be desirable. Culturing respiratory samples may be useful for diagnosing secondary bacterial pneumonia.

PURPOSE: The present study aimed to compare the capabilities of preoperative usual and maximal gait speeds in predicting functional recovery in patients who have undergone total hip arthroplasty (THA). METHODS: Primary and unilateral THAs were performed in 317 patients, and the proportion of patients who achieved unassisted walking (functional recovery) 5 days postoperatively was recorded as an outcome measure. Preoperative functional assessment included hip pain, leg muscle strength, range of motion (ROM), and gait speed evaluations. The capabilities of preoperative usual and maximal gait speeds in predicting functional recovery were compared based on the areas under the curves (AUCs) of receiver operating characteristic (ROC) curves. Further, ROC curves were constructed using two models: 1. a model of gait speed only and 2. a clinical model including age, sex, leg muscle strength, and ROM. RESULTS: On the AUCs for predictive ability of functional recovery, maximal gait speed was greater than usual gait speed (0.66 and 0.70, respectively). The AUC for maximal gait speed was as large as that of the clinical model (0.70 and 0.70, respectively). CONCLUSION: Our results suggest that maximal gait speed is a simple and useful prognostic indicator of functional recovery in patients who have undergone THA.

BACKGROUND: Strengthening the infraspinatus is important in shoulder rehabilitation. Changes in infraspinatus activity with changing load and position have not been quantified. We sought to determine the most appropriate load and posture for early infraspinatus strengthening by assessing for changes in electromyographic activity in the healthy infraspinatus and other shoulder girdle muscles during isometric external rotational exercise under different loads with the shoulder adducted in the supine and seated positions. METHODS: Sixteen healthy adults (30 shoulders) performed isometric shoulder external rotation in the sitting and supine positions, starting with the shoulder and forearm in neutral position and the elbow flexed 90°. Loads (0.5 kg, 1 kg, and 2 kg) were applied at rest. We assessed the infraspinatus, upper trapezius, posterior deltoid, and biceps brachii. For analysis, we used the mean percentage of maximum voluntary muscle contraction (%MVC) value measured during each isometric contraction divided by the maximum voluntary muscle contraction (MVC) of each muscle. RESULTS: In the infraspinatus and posterior deltoid, significant interaction was observed between body position and load. Compared to the sitting position, an increase in activity in the supine position was attenuated as load increased, especially at 2 kg. The supine values of the upper trapezius and biceps brachii were always significantly lower than those in the sitting position regardless of load. CONCLUSION: The activity of the infraspinatus can be increased gradually during rehabilitation by beginning in the supine position, which assures low activity of the upper trapezius and biceps brachii. Exercise with the shoulder adducted in the supine position can strengthen the infraspinatus gradually and avoid compensatory mobility. LEVEL OF EVIDENCE: Level 3.

STUDY DESIGN: A retrospective cohort study was performed. OBJECTIVE: The purpose of this study was to determine the efficacy and safety of stopping segmental pedicle screw instrumentation constructs at L5 in the treatment of neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA: Duchenne muscular dystrophy and spinal muscular atrophy are flaccid neuromuscular disorders in which gradual deterioration is the hallmark and have a lot of characteristics in common despite differences in etiology. Instrumentation and fusion to the sacrum/pelvis has been a mainstay in the surgical treatment of flaccid neuromuscular scoliosis and recommended to correct pelvic obliquity. However, the caudal extent of instrumentation and fusion in the surgical treatment of flaccid neuromuscular scoliosis has remained a matter of considerable debate and there have been few studies on the use of segmental pedicle screw instrumentation for flaccid neuromuscular scoliosis. METHOD: From 2005 to 2007, a total of 27 consecutive patients with neuromuscular disorders (20 Duchenne muscular dystrophy and 7 spinal muscular atrophy), aged 11 to 17 years, underwent segmental pedicle screw instrumentation and fusion only to L5. Assessment was performed clinically and with radiologic measurements. Minimum 2-year follow-up was required for inclusion in this study. RESULTS: Twenty patients were enrolled in this study. No patient was lost to follow-up. All patients had L5 tilt of less than 15° and a coronal curve with apex L2 or higher preoperatively. Preoperative coronal curve averaged 70° (range: 51°-88°), with a postoperative mean of 15° (range: 5°-25°) and 17° (range: 6°-27°) at the last follow-up. The pelvic obliquity improved from 15° (range: 9°-25°) preoperatively to 5° (range: 3°-8°) postoperatively and 6° (range: 3°-8°) at the last follow-up. The L5 tilt improved from 9° (range: 2°-14°) preoperatively to 2° (range: 0°-4°) postoperatively and 2° (range: 0°-5°) at the last follow-up. Physiologic sagittal plane alignment was recreated after surgery and maintained long-term. There was no significant loss of correction of coronal curve and pelvic obliquity. There was no major complication. CONCLUSION: Segmental pedicle screw instrumentation and fusion to L5 was safe and effective in patients with flaccid neuromuscular scoliosis with apex L2 or higher and minimal L5 tilt of less than 15°. Segmental pedicle screw instrumentation ending at L5 offered the ability to correct spinal deformity and pelvic obliquity initially, intermediate and even long-term, with no major complications. This method in appropriate patients can be a viable alternative to instrumentation and fusion to the sacrum/pelvis in the surgical treatment of flaccid neuromuscular scoliosis. LEVEL OF EVIDENCE: N/A.

BACKGROUND/OBJECTIVE: Few studies have addressed the type of time course regression that can predict changes in functional ability in inpatients with schizophrenia. This study investigated the possibility of predicting changes in functional ability by logarithmic and linear regression modelling when treating schizophrenia. METHODS: This longitudinal study included two analysis rounds. Analysis 1 comprised 40 inpatients (male/female: 16/24, mean age: 39.7 ± 13.5 years) for the identification of the time course of changes in functional ability based on the Activity Profile Scale for Patients with Psychiatric Disorders score from the group data. Analysis 2 comprised 17 inpatients (male/female: 9/8, mean age: 38.5 ± 9.4 years) to ensure correlation of the group data with the prediction of each individual's degree of functional ability. RESULTS: In Analysis 1, Activity Profile Scale for Patients with Psychiatric Disorders score was assessed at the initial occupational therapy visit, one week and one month thereafter, and at discharge; logarithmic modelling using the scores at the initial visit, one month later and at discharge was more suitable (R2 = .506, p < .001) than the logarithmic and linear regression models using other score combinations. In Analysis 2, the individual's predicted Activity Profile Scale for Patients with Psychiatric Disorders scores at discharge, as calculated by logarithmic modelling using scores from the initial visit and one month later, correlated moderately with actual Activity Profile Scale for Patients with Psychiatric Disorders scores (R2 = .574, p < .001; ICC = .747, p < .001). CONCLUSION: Logarithmic modelling based on Activity Profile Scale for Patients with Psychiatric Disorders score accurately predicted changes in the functional ability of inpatients with schizophrenia and is sufficiently uncomplicated to be adopted in daily clinical practice.
RESUMO
AIM: Decreasing behavioral independence levels and increasing frequencies of behavioral disturbances are the most problematic aspects for people with dementia. However, the relative effects of dementia on these factors are unknown. We investigated variability in behavioral independence and disturbance profiles of patients with dementia. METHODS: This was a cross-sectional correlation study in which 70 inpatients with dementia from convalescent wards in a hospital were enrolled. We assessed cognitive impairments with the Mini-Mental State Examination, evaluated behavioral independence levels with the Functional Independence Measure and assessed frequency of behavioral disturbances with the Dementia Behavior Disturbance Scale. RESULTS: Coefficient determination was 0.395 (P < 0.0001) between the Mini-Mental State Examination and Functional Independence Measure scores, 0.261 (P < 0.0001) between the Mini-Mental State Examination and Dementia Behavior Disturbance Scale scores, and 0.355 (P < 0.0001) between the Functional Independence Measure and Dementia Behavior Disturbance Scale scores. The most easily accomplished behavioral independence was eating, and the hardest was transfer to tub/shower. The behavioral disturbance with the highest frequency was urinary incontinence, and the lowest was emptying drawers or closets. CONCLUSIONS: Moderate correlations were found between severity of dementia and behavioral independence levels and frequencies of behavioral disturbances. There were both easier and harder to accomplish behaviors, and both higher and lower frequencies of behavioral disturbances. Geriatr Gerontol Int 2017; 17: 605-613.

[Purpose] Maintaining high quality of life is crucial for the rehabilitation of patients with Parkinson's disease. The quality of life scales currently in use do not assess all quality of life domains or their importance for each individual. Therefore, a new quality of life measure, the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting, was used to investigate quality of life in people with Parkinson's disease. [Subjects and Methods] Fifteen people with idiopathic Parkinson's disaese (average age = 80.0â years, standard deviation = 10.3â years, Hoehn & Yahr stages 1-4) were interviewed using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting. Its quality of life constructs were tested by comparing them against disease-specific quality of life (39-items Parkinson's Disease Questionnaire), motor functioning (Unified Parkinson's Disease Rating Scale Part III), and activities of daily living (Barthel Index). [Results] Social connections such as "family" and "friends" were revealed as important constructs of life satisfaction. The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting was not significantly correlated with the 39-items Parkinson's Disease Questionnaire, Unified Parkinson's Disease Rating Scale Part III, or Barthel Index but was significantly correlated with the "communication" dimension of the 39-items Parkinson's Disease Questionnaire. [Conclusion] The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting detected various domains of quality of life, especially social relationships with family and friends. "Being heard" was also revealed as an essential component of life satisfaction, as it provides patients with a feeling of acceptance and assurance, possibly resulting in better quality of life.
RESUMO
PURPOSE: An understanding of the repeatability of measured results is important for both the atlas-based and voxel-based morphometry (VBM) methods of magnetic resonance (MR) brain volumetry. However, many recent studies that have investigated the repeatability of brain volume measurements have been performed using static magnetic fields of 1-4 tesla, and no study has used a low-strength static magnetic field. The aim of this study was to investigate the repeatability of measured volumes using the atlas-based method and a low-strength static magnetic field (0.4 tesla). MATERIALS AND METHODS: Ten healthy volunteers participated in this study. Using a 0.4 tesla magnetic resonance imaging (MRI) scanner and a quadrature head coil, three-dimensional T1-weighted images (3D-T1WIs) were obtained from each subject, twice on the same day. VBM8 software was used to construct segmented normalized images [gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF) images]. The regions-of-interest (ROIs) of GM, WM, CSF, hippocampus (HC), orbital gyrus (OG), and cerebellum posterior lobe (CPL) were generated using WFU PickAtlas. The percentage change was defined as[100 × (measured volume with first segmented image - mean volume in each subject)/(mean volume in each subject)]The average percentage change was calculated as the percentage change in the 6 ROIs of the 10 subjects. RESULTS: The mean of the average percentage changes for each ROI was as follows: GM, 0.556%; WM, 0.324%; CSF, 0.573%; HC, 0.645%; OG, 1.74%; and CPL, 0.471%. The average percentage change was higher for the orbital gyrus than for the other ROIs. CONCLUSION: We consider that repeatability of the atlas-based method is similar between 0.4 and 1.5 tesla MR scanners. To our knowledge, this is the first report to show that the level of repeatability with a 0.4 tesla MR scanner is adequate for the estimation of brain volume change by the atlas-based method.

[Purpose] The purpose of this study was to assess the relationships between bilateral knee extension strengths and gait performance in subjects with poststroke hemiparesis and to predict gait performance by the paretic and nonparetic knee extension strength. [Subjects and Methods] This was a correlational study in which 238 consecutive inpatients with poststroke hemiparesis were enrolled. Knee extensor muscle strengths in paretic and nonparetic lower limbs were measured with a handheld dynamometer, and the presence or absence of impaired gait was also determined. [Results] The mean strength in the paretic lower limb was 0.90 Nm/kg, and that in the nonparetic lower limb was 1.24 Nm/kg. Discriminant analysis classified the difference between the possibility and impossibility of gait by knee extensor muscle strength (standardized discriminant coefficient: paretic, 1.32; nonparetic, 0.55). Thus, paretic and nonparetic knee extension strengths were integrated in the strength index. A threshold level of 2.0 provided the best balance between positive and negative predictive values for the strength index. [Conclusion] The results indicated that both paretic and nonparetic knee extension strengths were related to gait performance. The strength index deduced from bilateral knee extension strengths may serve as a clinically meaningful index for rehabilitation assessment and training.
RESUMO
BACKGROUND: This study attempted to assess continued long-term home care by examining patients' independent activities of daily living (ADLs) and caregivers' free time. METHODS: We surveyed the main caregivers of 52 patients with cerebrovascular disease with continuous home care from 1999 to 2010. Survey items were patients' ADLs, the frequency of use of care services, care requirements, and caregiver sense of burden. We compared the survey results between years. RESULTS: ADLs of excretory control, verbal expression, verbal comprehension, and range of activities showed significant deterioration from 1999 to 2010. Patient need for care increased significantly but use of care services did not. Main caregivers were typically spouses who aged together with the patients. Main caregivers rarely changed; occasionally, a son or daughter-in-law became the main caregiver. Patients typically required less than 3 hours of care daily, which did not change over time. Caregivers had significantly more difficulty maintaining their own health in 2010 than 1999. However, they did not identify increases in difficulties with housework or coping with work. They felt that caregiving was a burden but did not indicate that the family relationship had deteriorated. CONCLUSIONS: Regardless of degree of independence of patients' ADLs, caregiver burden was severe. To decrease caregiver burden, it is necessary to use care services, reduce care time, and allow caregivers free time. In addition, it is possible to continue long-term home care by maintaining their relationships.

The purpose of this study was to examine the reliability and validity of the Upper-body Dressing Scale (UBDS) for buttoned shirt dressing, which evaluates the learning process of new component actions of upper-body dressing in patients diagnosed with dementia and hemiparesis. This was a preliminary correlational study of concurrent validity and reliability in which 10 vascular dementia patients with hemiparesis were enrolled and assessed repeatedly by six occupational therapists by means of the UBDS and the dressing item of the Functional Independence Measure (FIM). Intraclass correlation coefficient was 0.97 for intra-rater reliability and 0.99 for inter-rater reliability. The level of correlation between UBDS score and FIM dressing item scores was -0.93. UBDS scores for paralytic hand passed into the sleeve and sleeve pulled up beyond the shoulder joint were worse than the scores for the other components of the task. The UBDS has good reliability and validity for vascular dementia patients with hemiparesis. Further research is needed to investigate the relation between UBDS score and the effect of intervention and to clarify sensitivity or responsiveness of the scale to clinical change.

BACKGROUND: Paired associative stimulation (PAS) is widely used to induce plasticity in the human motor cortex. Although reciprocal inhibition of antagonist muscles plays a fundamental role in human movements, change in cortical circuits for reciprocal muscles by PAS is unknown. METHODS: We investigated change in cortical plasticity for reciprocal muscles during PAS. PAS consisted of 200 pairs of peripheral electric stimulation of the right median nerve at the wrist at a frequency of 0.25 Hz followed by transcranial magnetic stimulation of the left M1 at the midpoint between the center of gravities of the flexor carpi radialis (FCR) and extensor carpi radialis (ECR) muscles. Measures of motor cortical excitability included resting motor threshold (RMT), GABAA-mediated short-interval intracortical inhibition (SICI), and GABAB-mediated long-interval intracortical inhibition (LICI). RESULTS: Motor evoked potential amplitude-conditioned LICI for the FCR muscle was significantly decreased after PAS (P = 0.020), whereas that for the ECR muscle was significantly increased (P = 0.033). Changes in RMT and SICI for the FCR and ECR muscles were not significantly different before and after PAS. Corticospinal excitability for both reciprocal muscles was increased during PAS, but GABAB-mediated cortical inhibitory functions for the agonist and antagonist muscles were reciprocally altered after PAS. CONCLUSION: These results implied that the cortical excitability for reciprocal muscles including GABAB-ergic inhibitory systems within human M1 could be differently altered by PAS.
