| Abstract |
Objective
Accelerometer is a convenient device that can easily measure human movement. The purpose of this study was to evaluate its usefulness in the assessment of hemiparetic gait after stroke.
Method
Twenty hemiparetic stroke patients were enrolled in the study. A portable accelerometer was attached between L3,4 intervertebral area. Vertical and medio-lateral acceleration was measured while walking 10 m. Walking ability of each subject was classified by Functional Walking Category (FWC).
Results
Accelerometric parameters, such as walking speed, a mean amount of peak vertical acceleration in one gaitcycle, mean peak value of unaffected side, peak vertical acceleration ratio, step time ratio were significantly higher in groups of FWC 4, 5, 6 than in groups of FWC 2, 3. In subjects using cane there was an extra peak other than peaks observed in non-users. Mean peak value, step length of unaffected side and cadence were significantly higher in non-users than in users.
Conclusion
Trunk accelerometer can be used as an objective method to evaluate walking ability in hemiparetic patients after stroke. (J Korean Acad Rehab Med 2006; 30: 62-68) |
