Abstract

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.

Abstract

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.

Abstract

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.
