Short-course remdesivir for healthcare-associated COVID-19: Case series from a non-acute care hospital.

Healthcare-associated COVID-19 among vulnerable patients leads to disproportionate morbidity and mortality. Early pharmacologic intervention may reduce negative sequelae and improve survival in such settings. This study aimed to describe outcome of patients with healthcare-associated COVID-19 who received early short-course remdesivir therapy. We reviewed the characteristics and outcome of hospitalized patients who developed COVID-19 during an outbreak that involved two wards at a non-acute care hospital in Japan and received short-course remdesivir. Forty-nine patients were diagnosed with COVID-19, 34 on a comprehensive inpatient rehabilitation ward and 15 on a combined palliative care and internal medicine ward. Forty-seven were symptomatic and 46 of them received remdesivir. The median age was 75, and the median Charlson comorbidity index was 6 among those who received it. Forty-one patients had received one or two doses of mRNA vaccines, while none had received a third dose. Most patients received 3 days of remdesivir. Of the patients followed up to 14 and 28 days from onset, 41/44 (95.3%) and 35/41(85.4%) were alive, respectively. Six deaths occurred by 28 days in the palliative care/internal medicine ward and two of them were possibly related to COVID-19. Among those who survived, the performance status was unchanged between the time of onset and at 28 days.

ADL Outcome of Stroke by Stroke Type and Time from Onset to Admission to a Comprehensive Inpatient Rehabilitation Ward.

OBJECTIVE: To examine the effect of onset to admission interval (OAI) and stroke type on activities of daily living (ADL) outcome. MATERIALS AND METHODS: Stroke patients (n=3112) admitted to and discharged from comprehensive inpatient rehabilitation wards at Nanakuri Memorial Hospital were classified into 8 OAI segments and by stroke type [intracerebral hemorrhage (ICH) and cerebral infarction (CI)]. Motor subscore of the Functional Independence Measure (FIM-M) on admission, FIM-M at discharge, FIM-M gain, length of stay (LOS), and FIM-M efficiency in the ICH and CI group matched by OAI segment were compared using the Wilcoxon test. Multiple comparisons using the Steel-Dwass test of FIM-M on admission, FIM-M at discharge, FIM-M gain, LOS, and FIM-M efficiency by OAI segments were performed. RESULTS: FIM-M on admission was lower in the ICH group than the CI group in matched OAI segments. However, FIM-M improvement was greater in the ICH group than the CI group, resulting in no difference in FIM-M between groups at discharge. In both groups, the longer the OAI, the lower the FIM-M on admission and at discharge. The distribution pattern of significant differences among OAI segments differed between the groups. LOS tended to be longer and FIM-M efficiency tended to be higher in the ICH group than in the CI group. CONCLUSIONS: The brain mass effect at the time of admission was larger and took longer to decrease in the ICH group than in the CI group. These results may improve prediction of outcomes in comprehensive inpatient rehabilitation wards.

Aphasia Following Left Putaminal Hemorrhage at a Rehabilitation Hospital.

OBJECTIVE: We aimed to clarify the relationship between aphasia and hematoma type/volume in patients with left putaminal hemorrhage admitted to a rehabilitation facility. METHODS: We evaluated the relationship between the presence, type, and severity of aphasia and hematoma type/volume in 92 patients with putaminal hemorrhage aged 29-83 years. Hematoma type and volume were evaluated on the basis of CT images obtained at stroke onset. The Standard Language Test for Aphasia was conducted as part of the initial assessment. RESULTS: Aphasia was observed in 79 of 92 patients. A total of 31 patients had fluent aphasia, while 48 had non-fluent aphasia. Non-fluent aphasia often involved hematoma on the anterior limb of the internal capsule, while fluent aphasia often involved hematoma on the posterior limb of internal capsule. When the hematoma volume exceeded 20 mL, patients experienced difficulty in repeating spoken words. When hematoma volume exceeded 40 mL, non-fluent aphasia was observed in all patients. CONCLUSION: Our findings suggest that hematoma type and volume not only influence the development of aphasia following putaminal hemorrhage but also play a major role in determining the patient's fluency and repetition ability.

Factors necessary for independent walking in patients with thalamic hemorrhage.

BACKGROUND: Thalamic hemorrhages cause motor paralysis, sensory impairment, and cognitive dysfunctions, all of which may significantly affect walking independence. We examined the factors related to independent walking in patients with thalamic hemorrhage who were admitted to a rehabilitation hospital. METHODS: We evaluated 128 patients with thalamic hemorrhage (75 men and 53 women; age range, 40-93 years) who were admitted to our rehabilitation hospital. The mean duration from symptom onset to rehabilitation hospital admission was 27.2 ± 10.3 days, and the mean rehabilitation hospital stay was 71.0 ± 31.4 days. Patients' neurological and cognitive functions were examined with the National Institutes of Health Stroke Scale (NIHSS) and Mini-Mental State Examination (MMSE), respectively. The relationship between patients' scores on these scales and their walking ability at discharge from the rehabilitation hospital was analyzed. Additionally, a decision-tree analysis was used to create a model for predicting independent walking upon referral to the rehabilitation hospital. RESULTS: Among the patients, 65 could walk independently and 63 could not. The two patient groups were significantly different in terms of age, duration from symptom onset to rehabilitation hospital admission, hematoma type, hematoma volume, neurological symptoms, and cognitive function. The decision-tree analysis revealed that the patient's age, NIHSS score, MMSE score, hematoma volume, and presence of ventricular bleeding were factors that could predict independent walking. CONCLUSIONS: In patients with thalamic hemorrhage, the neurological symptoms, cognitive function, and neuroimaging factors at onset are useful for predicting independent walking.

Potential factors, including activities of daily living, influencing home discharge for patients with putaminal haemorrhage.

BACKGROUND: Convalescent rehabilitation wards assist stroke patients in acquiring skills for activities of daily living to increase the likelihood of home discharge. However, an improvement in activities of daily living does not necessarily imply that patients are discharged home. We investigated the characteristics of patients with putaminal haemorrhage who are discharged home following convalescence in rehabilitation wards. METHODS: The sample comprised 89 patients (58 men and 31 women) with putaminal haemorrhage hospitalised in the convalescent rehabilitation ward of our hospital between August 2012 and July 2013. Their age ranged from 29 to 88 years (61.9 ± 11.9 years). The lesion occurred on the right side in 48 and on the left in 41 patients. The mean period from onset to hospitalisation in the convalescent rehabilitation ward was 30.8 ± 17.2 days, and the mean hospitalisation period was 70.7 ± 31.8 days. We examined age, sex, haematoma volume, duration from onset to hospitalisation, neurological symptoms, cognitive function, functional independence measure, number of cohabitating family members and whether the patient lived alone before stroke, and the relationship among these factors and discharge destination (home or facility/hospital) was assessed. RESULTS: The discharge destination was home for 71 and a facility or hospital for 18 patients. Differences were observed in age, haematoma volume, neurological symptoms, cognitive function, functional independence measure score on admission and discharge, number of cohabitating family members and whether the patient lived alone before stroke for patients discharged home. Patients who required long-term care and were discharged home were more likely to be living with family members who were present during daytime. Home discharge was possible if functional independence measure score was ≥70 at the time of discharge for motor items and ≥24 for cognitive items, even if a patient lived alone before stroke. CONCLUSIONS: Although the presence of cohabitating family members was important, the factor most strongly influencing home discharge was the patient's activities of daily living status at the time of discharge. For patients who lived alone before stroke, physical and cognitive functions must be maintained for them to be discharged home after rehabilitation.

Electromyography of Swallowing with Fine Wire Intramuscular Electrodes in Healthy Human: Amplitude Difference of Selected Hyoid Muscles.

Few studies have examined the intensity of muscle activity during swallowing in healthy humans. We examined selected hyoid muscles using fine wire intramuscular electromyography (EMG) during swallowing of four food consistencies. Thirteen healthy adults were studied using videofluorography and EMG of the anterior belly of digastric (ABD), geniohyoid (GH), sternohyoid (SH), and masseter (MA; surface electrodes) while ingesting thin liquid (three trials) and solid food of three consistencies (banana, tofu, and cookie, three trials each). After rectification, integration, and normalization, peak EMG amplitudes for each muscle in each trial were measured. Hyoid displacements were measured in two dimensions. Data were analyzed using repeated measures ANOVA with Bonferroni correction. GH had the highest adjusted amplitude for both solids and liquid. For MA and ABD, amplitude was highest with triturated cookie. For ABD, amplitude was lowest with liquid. There were no significant food consistency effects for GH or SH. Hyoid displacements were greatest for cookie and the lowest for liquid. EMG amplitude varied with initial food consistency. The high peak EMG amplitude of GH is consistent with its essential role in opening the upper esophageal sphincter. High MA amplitude with hard solid foods is likely due to the higher tongue-palate pressure with triturated solids. The higher ABD amplitude with solid food is associated with greater hyoid displacement. These findings support the existence of a central pattern generator that modifies the level of muscle activity during pharyngeal swallowing in response to input from mechanoreceptors in the oral cavity.

Dysphagia Following Putaminal Hemorrhage at a Rehabilitation Hospital.

BACKGROUND: Dysphagia occurs frequently during the acute phase of cerebral hemorrhage; however, there are few reports of dysphagia associated with cerebral hemorrhage in the subacute and chronic phase. We focused on putaminal hemorrhage at a rehabilitation hospital and evaluated the relationships between the frequencies of dysphagia, focus, and hematoma volume and type. METHODS: A hundred patients with putaminal hemorrhage referred to our rehabilitation hospital were evaluated. Bedside swallowing assessments (BSAs) were conducted and results were evaluated relative to the information obtained on computed tomography imaging, including hematoma type and volume, and oral intake at the time of admission/discharge from the hospital. RESULTS: A regular diet was provided to 48 patients, dysphagia diet to 44 patients, and enteral feeding to 8 patients. There were significant feeding group differences in age, hematoma volume and type, existence of ventricle rupture, neurological manifestation, cognitive function, existence of unilateral neglect and aphasia, initial BSA, activities of daily living (ADL) score using the Functional Independence Measure at the time of admission/discharge from the hospital, and length of stay. At discharge, we provided a regular diet to 81 patients and dysphagia diet to 19 patients. Age and ADL score had the greatest influence on oral intake at the time of discharge from the hospital. CONCLUSION: The prognosis of dysphagia caused by putaminal hemorrhage is good, with no patient requiring enteral feeding, although putaminal hemorrhage often causes dysphagia. Patient age and ADL score on admission are used to predict the residual factors of dysphagia.

A comparison of knee-ankle-foot orthoses with either metal struts or an adjustable posterior strut in hemiplegic stroke patients.

BACKGROUND: We investigated differences in factors affecting judgments regarding the creation of new adjustable posterior strut knee-ankle-foot orthoses (APS-KAFO) and knee-ankle-foot orthoses with metal struts (traditional KAFO) for hemiplegic stroke patients for whom KAFO were created in rehabilitation wards. METHODS: Subjects were 50 patients with hemiplegia due to new-onset stroke (cerebral infarction: n = 25, cerebral hemorrhage: n = 25) who were prescribed KAFO. Patient ages ranged from 36 to 90 years, and the mean duration from stroke onset to hospitalization was 28.8 ± 13.8 days. Neurologic symptoms, cognitive function, activities of daily living, duration from hospitalization to orthosis creation, hospitalization duration, walking ability at discharge, outcome after discharge, and so forth were compared. RESULTS: Fourteen patients were prescribed APS-KAFO, and 36 were prescribed traditional KAFO. Those prescribed APS-KAFO had somewhat milder neurologic symptoms and cognitive dysfunction and a shorter hospitalization duration than those prescribed traditional KAFO. Patients prescribed APS-KAFO also had a higher score and efficiency on functional independence measure at admission and discharge. Walking independence at discharge was seen in 8 of the 14 patients for whom APS-KAFO were created and 8 of the 36 patients for whom traditional KAFO were created. CONCLUSIONS: APS-KAFO was chosen for patients with a high level of activity in the ward and with a higher likelihood of acquiring walking ability using APS-AFO at discharge, whereas traditional KAFO tended to be chosen for patients with relatively severe symptoms who were not expected to acquire practical walking ability.

Electromyography of swallowing with fine wire intramuscular electrodes in healthy human: activation sequence of selected hyoid muscles.

Few studies have reported the activation sequence of the swallowing muscles in healthy human participants. We examined temporal characteristics of selected hyoid muscles using fine wire intramuscular electromyography (EMG). Thirteen healthy adults were studied using EMG of the anterior belly of digastric (ABD), geniohyoid (GH), sternohyoid (SH), and masseter (MA, with surface electrodes) while ingesting thin liquid, banana, tofu, and cookie (3 trials each). Onset timing was measured from rectified and integrated EMG. Data were analyzed using repeated-measures ANOVA with Bonferroni correction. When drinking thin liquid, MA, GH, and ABD were activated almost simultaneously, but SH was activated later (using GH onset as 0 s, MA -0.07 (-0.20 to 0.17) second [median (interquartile range)]; ABD 0.00 (-0.10 to 0.07) second; SH 0.17 (0.02 to 0.37) second; P < 0.01). With solid foods, MA contraction preceded GH and ABD; SH was last and delayed relative to liquid swallows (GH 0 s; MA -0.17 (-0.27 to 0.07) second; ABD 0.00 (-0.03 to 0.03) second; SH 0.37 (0.23 to 0.50) second; P < 0.01). The role of the MA differs between solids and liquids so the variation in its timing is expected. The synchronous contraction of GH and ABD was consistent with their role in hyolaryngeal elevation. The SH contracted later with solids, perhaps because if the longer duration of the swallow. The consistent pattern among foods supports the concept of a central pattern generator for pharyngeal swallowing.

Changes in serum growth factors in stroke rehabilitation patients and their relation to hemiparesis improvement.

Predicting recovery from hemiparesis after stroke is important for rehabilitation. A few recent studies reported that the levels of some growth factors shortly after stroke were positively correlated with the clinical outcomes during the chronic phase. The aim of this study was to examine the relationships between the serum levels of growth factors (vascular endothelial growth factor [VEGF], insulin-like growth factor-I [IGF-I], and hepatocyte growth factor [HGF]) and improvement in hemiparesis in stroke patients who received rehabilitation in a postacute rehabilitation hospital. Subjects were 32 stroke patients (cerebral infarction: 21 and intracerebral hemorrhage [ICH]: 11). We measured serum levels of VEGF, IGF-I, and HGF and 5 items of the Stroke Impairment Assessment Set (SIAS) for hemiparesis on admission and at discharge. Age-matched healthy subjects (n=15) served as controls. Serum levels of VEGF and HGF in cerebral infarct patients on admission were higher than those in control subjects, and the serum levels of IGF-I in stroke patients were lower than those in controls. The level of HGF in ICH patients on admission was negatively correlated with gains in SIAS, and higher outliers in HGF concentration were correlated with lower gains in SIAS. Focusing on the extremely high levels of these factors may be a predictor of the low recovery from hemiparesis after stroke.

Effect of combining an upper limb rehabilitation support robot with task-oriented training on severe upper limb paralysis after spinal cord infarction: A case report.

Yokoi A, Miyasaka H, Ogawa H, Itoh S, Okazaki H, Sonoda S. Effect of combining an upper limb rehabilitation support robot with task-oriented training on severe upper limb paralysis after spinal cord infarction: A case report. Jpn J Compr Rehabil Sci 2024; 15: 42-48. Objective: This study examined the effect of an upper limb rehabilitation support robot and task-oriented training on treating a patient with severe upper limb paralysis after spinal cord infarction who required total assistance with self-care. Case: A 60-year-old man was diagnosed with watershed infarction in the C5-7 spinal cord region. He was admitted to our hospital 18 days after onset of the disease. The patient had severe paralysis of both upper limbs, and the total score for the Functional Independence Measure (FIM) motor items was 25 points. Regarding the Canadian Occupational Performance Measure (COPM), three goals were listed: "eating," "going to the toilet," and "raising one's hand in a meeting." The performance of "going to the toilet" was rated three points, and the performance and satisfaction of other items were one point. The intervention was practiced for 1 h/day, mainly items selected from COPM. The training using an upper limb rehabilitation support robot was added for 1 h/day. The upper limb rehabilitation support robot adjusted the range of motion and dosage according to the patient's motor function level and recovery status. About three months after admission, he improved until his upper limbs could be held in space on activities of daily living (ADL), and the total score for the FIM motor items improved to 81 points. The satisfaction and performance of all items listed as goals in COPM at the time of admission improved to ten points, and the patient was discharged 108 days after admission. Conclusions: The upper limb rehabilitation support robot training that matched the level of motor function improved the motor function and active range of motion (ROM). ADL generalization through task-oriented training helped improve self-care. The use of COPM for the training to enable the patient to acquire the ability to perform meaningful activities led to improved COPM performance and satisfaction.

Fluoroscopic evaluation of tongue and jaw movements during mastication in healthy humans.

When chewing solid food, part of the bolus is propelled into the oropharynx before swallowing; this is named stage II transport (St2Tr). However, the tongue movement patterns that comprise St2Tr remain unclear. We investigated coronal jaw and tongue movements using videofluorography. Fourteen healthy young adults ate 6 g each of banana, cookie, and meat (four trials per foodstuff). Small lead markers were glued to the teeth and tongue surface to track movements by videofluorography in the anteroposterior projection. Recordings were divided into jaw motion cycles of four types: stage I transport (St1Tr), chewing, St2Tr, and swallowing. The range of horizontal tongue motion was significantly larger during St1Tr and chewing than during St2Tr and swallowing, whereas vertical tongue movements were significantly larger during chewing and St2Tr than during swallowing. Tongue movements varied significantly with food consistency. We conclude that the small horizontal tongue marker movements during St2Tr and swallowing were consistent with a "squeeze-back" mechanism of bolus propulsion. The vertical dimension was large in chewing and St2Tr, perhaps because of food particle reduction and transport in chewing and St2Tr.

Influence of sitting posture on anterior buttock sliding during wheelchair propulsion of hemiplegic stroke patients.

Miyasaka H, Nakagawa Y, Okazaki H, Sonoda S. Influence of sitting posture on anterior buttock sliding during wheelchair propulsion of hemiplegic stroke patients. Jpn J Compr Rehabil Sci 2023; 14: 54-59. Objectives: This study investigated the influence of different sitting postures on wheelchair propulsion ability. Methods: The subjects were stroke patients who scored at least 2 points on the Stroke Impairment Assessment Set for abdominal muscle strength and trunk verticality and 3 points for non-paralytic side lower-limb muscle strength. Moreover, the patients were divided by their everyday wheelchair propulsion posture: Lean on Back Support (LBS); n = 8), those who leaned their back against the back support; and non-LBS (n = 11), those who moved their back away from the back support. For the wheelchair propulsion method, straight one-hand, one-leg propulsion was used on the non-paralyzed side for 10 m, followed by turning around a target 3 m ahead on each of the paralyzed and non-paralyzed sides. We then compared the propulsion times, number of propulsions, and difference in length from the front end of the patella on the non-paralyzed side to the front end of the seat surface (buttock sliding distance) between the groups. Results: The buttock sliding distance was significantly shorter in the non-LBS group than in the LBS group in the paralyzed and non-paralyzed side turning tasks (p < 0.05). Propulsion times, number of propulsions, and grip strength did not differ significantly between the groups. Conclusion: Even in patients with good trunk function, propulsion while leaning against the back support can easily result in anterior buttock sliding, leading to a secondary risk of injury. These results suggest that it is necessary to provide guidance on the propulsion posture and seating to hold the trunk vertically to minimize anterior sliding during propulsion.

A new system to measure the trunk angle and pelvis angle during wheelchair propulsion.

BACKGROUND: The number of wheelchair users is increasing as the population ages. However, there is still lack of tools to objectively assess posture during wheelchair propulsion. OBJECTIVE: The purpose of this study was to develop a system to measure trunk and pelvis ROM (range of motion) while driving a wheelchair and to assess the reproducibility of the measured posture changes and cyclic fluctuations during propulsion. METHODS: Motion recorders were attached to the sternum and pelvis of fifteen healthy adults, and a pressure sensor was attached to the right heel. Subjects drove a standard wheelchair using their right leg and trunk and pelvis ROM was measured in two separate sessions. To detect the trend of postural changes during propulsion, a trend curve was computed from the measured ROM using a low-pass filter and then subtracted from the measured ROM waveforms. The resulting curves were normalized and averaged, and the maximum, minimum, and amplitude of the cyclic variation during propulsion were assessed for reproducibility. RESULTS: Intraclass correlation coefficients of the maximum, minimum, and amplitude ranged from 0.65 to 0.84. CONCLUSIONS: The proposed method can estimate the posture change and the periodic fluctuation during wheelchair propulsion with high reproducibility.

Kinematics of lateral tongue-pushing movement in coordination with masticatory jaw movement: An anteroposterior projection videofluorographic study.

OBJECTIVE: During the mastication of solid food, the tongue pushes the bolus laterally to place it onto occlusal surfaces as the jaw is opened. This movement is referred to as tongue-pushing (TP). TP has an important role in efficient chewing, but its kinematic mechanisms remain unclear. The present study quantified the kinematics of TP and its coordination with masticatory jaw movements. METHODS: Videofluorography (VFG) in anteroposterior projection was recorded while 14 healthy young adults ate 6 g each of cookies and meat. Small lead markers were glued to the tongue surface (left, right, and anterior) and buccal tooth surfaces (upper molars and lower canines). The position of the tongue and lower canine markers relative to the upper occlusal plane was quantified with Cartesian coordinates, using the right upper molar as the origin. Jaw motion during chewing was divided into TP and Non-TP cycles, based on the lateral movement of the food and tongue markers. The side of the jaw that compressed food particles was defined as the working side, while the other side was termed the balancing side. Horizontal and vertical displacements of tongue and jaw markers were compared between TP and Non-TP cycles, as well as between food types. RESULTS: The mediolateral displacement of all tongue markers was significantly larger in TP than in Non-TP cycles. Vertical displacement was also significantly greater in TP than in Non-TP cycles for the anterior and working side tongue markers. TP cycles occurred more frequently with meat-chewing than with cookie-chewing. CONCLUSION: TP is accomplished by rotation and lateral movements of the tongue surface on the working side and the anterior tongue blade, along with medial movement on the balancing side. These movements produce lateral shift and rotation of the tongue surface toward the working side in concert with jaw opening. Designing exercises to improve the strength of the lateral motion and rotation of the tongue body may be useful for individuals with impaired tongue function for eating and swallowing.

A Tablet-Based Aphasia Assessment System "STELA": Feasibility and Validation Study.

BACKGROUND: There is an extensive library of language tests, each with excellent psychometric properties; however, many of the tests available take considerable administration time, possibly bearing psychological strain on patients. The Short and Tailored Evaluation of Language Ability (STELA) is a simplified, tablet-based language ability assessment system developed to address this issue, with a reduced number of items and automated testing process. OBJECTIVE: The aim of this paper is to assess the administration time, internal consistency, and validity of the STELA. METHODS: The STELA consists of a tablet app, a microphone, and an input keypad for clinician's use. The system is designed to assess language ability with 52 questions grouped into 2 comprehension modalities (auditory comprehension and reading comprehension) and 3 expression modalities (naming and sentence formation, repetition, and reading aloud). Performance in each modality was scored as the correct answer rate (0-100), and overall performance expressed as the sum of modality scores (out of 500 points). RESULTS: The time taken to complete the STELA was significantly less than the time for the WAB (mean 16.2, SD 9.4 vs mean 149.3, SD 64.1 minutes; P<.001). The STELA's total score was strongly correlated with the WAB Aphasia Quotient (r=0.93, P<.001), supporting the former's concurrent validity concerning the WAB, which is a gold-standard aphasia assessment. Strong correlations were also observed at the subscale level; STELA auditory comprehension versus WAB auditory comprehension (r=0.75, P<.001), STELA repetition versus WAB repetition (r=0.96, P<.001), STELA naming and sentence formation versus WAB naming and word finding (r=0.81, P<.001), and the sum of STELA reading comprehension or reading aloud versus WAB reading (r=0.82, P<.001). Cronbach α obtained for each modality was .862 for auditory comprehension, .872 for reading comprehension, .902 for naming and sentence formation, .787 for repetition, and .892 for reading aloud. Global Cronbach α was .961. The average of the values of item-total correlation to each subscale was 0.61 (SD 0.17). CONCLUSIONS: Our study confirmed significant time reduction in the assessment of language ability and provided evidence for good internal consistency and validity of the STELA tablet-based aphasia assessment system.

Predicting walking ability in hemiplegic patients with putaminal hemorrhage: an observational study in a rehabilitation hospital.

BACKGROUND: In stroke rehabilitation, the most important concern of the patients and their families is whether the patients can walk independently and whether they need braces after discharge. AIM: This study aims to investigate the relationship between several types of putaminal hemorrhage and walking independence and orthotic therapy in patients with hemiplegia. DESIGN: Observational study. SETTING: Inpatients rehabilitation department, Fujita Health University Nanakuri Memorial Hospital, Japan. POPULATION: Total 264 patients with putaminal hemorrhage admitted to our hospital. METHODS: Neurological and cognitive functions were examined as per the stroke scale of the National Institutes of Health and the Mini-mental state examination, respectively. The hematomas were classified into five types, and the volume was measured using computed tomography (CT). Walking ability was evaluated by Functional Ambulation Category (FAC), and walking independence was defined as FAC ≥4. The relationship between the types of hematomas and walking independence and orthotic therapy in patients with hemiplegia with putaminal hemorrhage was also analyzed. RESULTS: We observed differences within the hematoma types in volume, neurological symptoms, and cognitive function but not in age, sex, and lesion side aspects of these patients - 143 of whom could walk independently (FAC≥4) and 121 non-independently. Walking independently and the need for orthosis were closely related to the type of hematoma. CONCLUSIONS: CT imaging at stroke onset can provide useful information when examining walking independence and indicate necessity for an orthosis at the time of discharge to the rehabilitation ward. CLINICAL REHABILITATION IMPACT: This study might help to better understand the role of neuroimaging in stroke rehabilitation.

Pattern of item score change in Stroke Impairment Assessment Set in comprehensive inpatient rehabilitation wards.

OBJECTIVES: Although numerous studies have examined activities of daily living (ADL) in stroke rehabilitation, there has been little focus on impairment, despite its close relationship to ADL. Therefore, we evaluated the change in impairment from admission to discharge of patients with stroke in comprehensive inpatient rehabilitation wards using the Stroke Impairment Assessment Set (SIAS). METHODS: Data from 3279 patients with first stroke who were admitted to comprehensive inpatient rehabilitation wards between 2004 and 2016 were analyzed. A scattergram of the items showing the percentage of the highest score on admission and the percentage of patients whose score improved during hospitalization was plotted. The items of the SIAS were grouped by their location on the scattergram. RESULTS: Three clusters could be discriminated on the scattergram. The upper right group, showed an improved score during hospitalization in combination with a high percentage of patients with the highest score on admission. This group consisted of the verticality, unaffected-side quadriceps, visuospatial, and pain items of the SIAS. The upper left group improved during hospitalization, but only contained a small percentage of patients with a high score on admission, and consisted of motor function items. The lower group was characterized by poor improvement during hospitalization and consisted of sensory, tone, range of motion, speech, and grip power items. CONCLUSIONS: Understanding the change in impairment during hospitalization using the three groups described above will facilitate design of a plan for stroke rehabilitation on admission.

Evaluation of use of the Medical Outcome Study 36-Item Short Form Health Survey and cognition in patients with stroke.

The Medical Outcome Study 36-Item Short Form Health Survey (SF-36) is a widely used method to evaluate health-related quality of life and has been applied for patients with stroke. However, because it is a self-assessment tool, there is a risk in using results of the survey because of lack of information on patients who cannot answer the questionnaire. For this report, 38 patients with stroke hospitalized in the rehabilitation department filled out the SF-36 and motor items of the Functional Independence Measure (FIM) and the Stroke Impairment Assessment Set. We then examined characteristics of patients who could not be evaluated by the SF-36. Of the 38 patients, 19 patients could and 19 patients could not be evaluated by the SF-36. There was no remarkable relationship among capacity or incapacity for evaluation by the SF-36, motor subscores on the FIM, and motor items on the Stroke Impairment Assessment Set. All 10 patients having a communication subscore on the FIM of 10 points or less and/or a social cognition subscore on the FIM of 13 points or less could not be evaluated by the SF-36. The remaining unevaluable patients were not cooperative. Studies in which the entry criteria include the ability to answer the SF-36 questionnaire neglect patients with poor cognition. Therefore, when administering the SF-36 for patients with stroke, we recommend using an interview setting.
