Objective
To determine whether post-stroke patient’s perceived exertion correlates with effort intensity score as measured by a wearable sensor and to assess whether estimates of perceived exertion are correlated to the cerebral hemisphere involved in the stroke.
Methods
We evaluated the effort intensity score during physiotherapy sessions using a wearable sensor and subjects assessed their perceived exertion using the modified Borg CR10 Scale.
Results
Fifty-seven subacute stroke patients participated in the study. The correlation between perceived exertion rating and measured effort intensity was insignificant—mean (r=-0.04, p=0.78) and peak (r=-0.05, p=0.70). However, there was a significant difference (p<0.02) in the perceived exertion ratings depending on the cerebral hemisphere where the stroke occurred. Patients with left-hand side lesions rated their perceived exertion as 4.5 (min–max, 0.5–8), whereas patients with right-hand side lesions rated their perceived exertion as 5.0 (2–8).
Conclusion
While there was an insignificant correlation between perceived exertion and effort intensity measured by a wearable sensor, a consistent variations in perceived exertion estimates according to the side of the cerebral lesion was identified and established.

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)

Objective
The aim of this study is to evaluate the acceleration of the center of mass (COM) of the body in stroke patients.Method: Seventeen stroke patients and 9 normal subjects were participated. Three dimensional gait analysis was used to classify gait phases for the reference. The accelerometer held over the COM were used to record vertical and medio- lateral accelerations of the COM of the body. Modified Ashworth scale and Brunnstrom stage were used to evaluate the clinical status of stroke patients.Results: In normal subjects, the acceleration showed symmetric pattern. The maximum peak of vertical acceleration occurred in loading response. In stroke patients, theacceleration wave was characterized by asymmetry and polyphasicity. Maximum peak in affected side was higher than that in unaffected side (p＜0.05). There were significant correlations between several elements of hemiplegic gait and the correspondent acceleration values; interval of successive peak I in vertical acceleration vs. step time, walking velocity and swing symmetry ratio vs. mean peak I, swing symmetry ratio vs. affected side peak I, step length symmetry ratio vs. peak I symmetry ratio.Conclusion: The accelerometer can be an easy and useful way to evaluate gait characteristics in stroke patients.
