Objective: To clarify the time-course of longitudinal changes in the independence level of subtasks composing bed–wheelchair transfer among patients with stroke.Design: Single-institution prospective cohort study.Patients: A total of 137 consecutive post-stroke patients using wheelchair on admission to the subacute rehabilitation wards.Methods: The independence degree in each of the 25 transfer-related subtasks was assessed using the Bed–Wheelchair Transfer Tasks Assessment Form on a three-level scale every two weeks, from admission to the endpoint (either discharge or when achieving independent transfer). Patients were classified based on admission and endpoint assessment form scores using two-step cluster analysis.Results: Patients were classified into three clusters. The first cluster included 50 patients who exhibited a greater independence level in all subtasks on admission (52.0–100% of patients performed each subtask independently) and at the endpoint (64.0–100%). The second included 30 patients who showed less independence on admission (0–27.8%) but achieved greater independence levels at the endpoint (44.4–97.2%). The third included 51 patients whose independence level remained low in many subtasks from admission (0–5.8%) until the endpoint (0–29.4%).Conclusion: The independence level and its changing process during transfer were categorized into three time-courses, each requiring different intervention strategies.

Introduction Qualitative information in the form of written reflection reports is vital for evaluating students’ progress in education. As a pilot study, we used text mining, which analyzes qualitative information with quantitative features, to investigate how rehabilitation students’ goals change during their first year at university. Methods We recruited 109 first-year students (66 physical therapy and 43 occupational therapy students) enrolled in a university rehabilitation course. These students completed an open-ended questionnaire about their learning goals at the time of admission and at 6 and 12 months after admission to the university. Text mining was used to objectively interpret the descriptive text data from all three-time points to extract frequently occurring nouns at once. Then, hierarchical cluster analysis was performed to generate clusters. The number of students who mentioned at least one noun in each cluster was counted and the percentages of students in each cluster were compared for the three periods using Cochran’s Q test. Results The 31 nouns that appeared 10 or more times in the 427 sentences were classified into three clusters: “Socializing,” “Practical Training,” and “Classroom Learning.” The percentage of students in all three clusters showed significant differences across the time periods (p < 0.001 for “Socializing”; p < 0.01 for “Practical Training” and “Classroom Learning”). Conclusion These findings suggest that the students’ learning goals changed during their first year of education. This objective analytical method will enable researchers to examine transitional trends in students’ reflections and capture their psychological changes, making it a useful tool in educational research.

OBJECTIVE: To evaluate the effectiveness of a dyadic outpatient rehabilitation program focused on improving the real-life daily activities of patients with mild cognitive impairments or dementia and their caregivers. DESIGN: Retrospective study. SUBJECTS: Eight patients with mild cognitive impairments or dementia and their caregivers. METHODS: The rehabilitation program comprised eight 1-hour sessions by occupational therapists with patients and his/her caregivers. Patients were assessed for motor function, cognitive function, and quality of life, and their caregivers were assessed for depression and caregiver burden. Participants were assessed at pre-program and post-program, and 3-month follow-up. RESULTS: The scores of caregiver-assessed Quality of life in Alzheimer's disease scale in patients significantly improved at post-program (median [interquartile range], 30.0 [7.0]) compared with pre-program (27.0 [2.8], effect size = 0.77, p = 0.029). In caregivers, the Zarit Caregiver Burden Interview scores decreased significantly at post-program (16.5 [13.0]) compared with pre-program (22.0 [17.5], effect size = 0.72, p = 0.042). There were no significant differences in other assessments. CONCLUSIONS: The rehabilitation program focused on real daily activities and demonstrated to improve patients' quality of life and caregivers' depression and caring burden through patient-caregiver interaction. Future enhanced follow-up systems are warranted.

Arm reaching is often impaired in individuals with stroke. Nonetheless, how aiming directions influence reaching performance and how such differences change with motor recovery over time remain unclear. Here, we elucidated kinematic parameters of reaching toward various directions in people with post-stroke hemiparesis in the sub-acute phase. A total of 13 and 15 participants with mild and moderate-to-severe hemiparesis, respectively, performed horizontal reaching in eight directions with their affected and unaffected sides using an exoskeleton robotic device at admission and discharge. The movement time, path length, and number of velocity peaks were computed for the mild group (participants able to reach toward all eight directions). Additionally, the total amount of displacement (i.e., movement quantity) toward two simplified directions (mediolateral or anteroposterior) was evaluated for the moderate-to-severe group (participants who showed difficulty in completing the reaching task). Motor recovery was evaluated using the Fugl-Meyer Assessment.The mild group exhibited decreases in movement parameters when reaching in the anteroposterior direction, irrespective of the side of the arm or motor recovery achieved. The moderate-to-severe group exhibited less movement toward the anteroposterior direction than toward the mediolateral direction at admission; however, this direction-dependent bias in movement quantity decreased, with the movement expanding toward the anteroposterior direction with motor recovery at discharge. These results suggest that direction-dependent differences in the quality and quantity of reaching performance exist in people after stroke, regardless of the presence or severity of hemiparesis. This highlights the need to consider the task work area when designing rehabilitative training.
