[en] Mobility milestones are elementary movements related to activities of daily living (ADL) and have a significant influence on functional recovery after stroke. This study aimed to identify the factors affecting mobility milestones and to clarify the relationships between mobility milestones and ADL. Participants were in the acute phase after first-ever strokes (ischemic, n=77; hemorrhagic, n=84). Clinical and radiological factors within the first week were determined and their effects on mobility milestones after 4 weeks were analyzed using logistic regression analysis. After 4 weeks the patients were divided into four groups on the basis of sitting balance, standing balance, and walking ability. Then total ADL score was calculated using the Barthel index (BI), and percentage of independent patients in each 10 items of BI was transition rate of ADL for each of the four groups. Patients with ischemic stroke showed the following findings. Sitting balance was affected by severity of lower limb paralysis, consciousness level, and presence of an internal capsule lesion on computed tomography (CT) (R²=0.86); standing balance was influenced by severity of lower limb paralysis and consciousness level (R²=0.72); and walking ability was affected by severity of lower limb paralysis (R²=0.64). Patients with hemorrhagic stroke showed the following findings. Sitting balance was influenced by severity of lower limb paralysis, intraventricular hemorrhage on CT, blood pressure instability, and fever (R²=0.75); standing balance was affected by severity of lower limb paralysis, consciousness level, and presence of an internal capsule lesion (R²=0.58); and walking ability was influenced by severity of lower limb paralysis and presence of an internal capsule lesion (R²=0.70). In both types of stroke, sitting and standing balance and walking ability were directly associated with total ADL score, and sitting and standing balance became independent earlier than ADL. Severity of lower limb paralysis, consciousness level, and imaging findings were identified as significant factors affecting mobility milestones. (author)
