Abstract
[Purpose] The aim of this study was to determine an optimal index that easily estimates low physical activity (LPA) of elderly hemiplegic patients. [Subjects] The participants were 25 day-care users and hemiplegic men with independent daily activity living. [Methods] In this study, an index was prepared to estimate the level of physical activity with posture and exercise intensity (PAPI) and the level of physical activity using METs methods (PAMETs). The effect of the index was evaluated using the double product (DP) obtained from multiplying heart rate with systolic blood pressure. The cut-off point was analysed to estimate the LPA based on this outcome. [Results] With respect to the outcome measured early in the morning, if the DP was higher than 8,000 (bpm × mmHg), the value determined in a deconditioning status. An receiver operating characteristic (ROC) analysis was performed in relation to PAPI and PAMETs for the predicted DP. The results revealed that the optimal cut-off point was significant with a PAPI of 1,250 kcal (p<0.05). Each PAMETs was not a significant index for assessing low physical activity. [Conclusion] The optimal index to estimate LPA may be considered the PAPI of 1,250 kcal.
