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.
