• The purpose of this study was to investigate how 18 elderly subjects with cerebral vascular accident (CVA) (14 men and 4 women) and 19 healthy elderly subjects (6 men and 13 women) would respond to a five-step graded unilateral sanding activity. Three indicators of pulmonary function such as expiratory tidal volume, respiratory rate, and expiratory volume and four indicators of cardiometabolic function such as metabolic equivalents (METS), systolic blood pressure, heart rate, and pressure rate product were continuously recorded during the exercise. Moreover, plasma catecholamine was analyzed from every subject's venous blood three times. The exercise with the two independent variables: angle of the sanding board and sanding velocity, consisted of five grades: (1) Grade 1: sitting at rest; (2) Grade 2: 0° at 15 cycles per minute (cpm); (3) Grade 3: 0° at 30 cpm; (4) Grade 4: 15° at 15 cpm; and (5) Grade 5: 15° at 30 cpm. The characteristic findings indicated that an increase of the angle with the constant velocity did not always increase the mean values of the pulmonary and cardiometabolic measures. However, the increase of the velocity with the constant angle always increased that of the dependent variables. The another valuable finding indicated that METS reached at the greatest work load did not demonstrate greater than 2, corresponding to a light activity in daily life such as sewing at machine. Moreover, the data on plasma catecholamine represented that the exercise did not exert stressful influence on the patients with CVA. The present study suggested that a five-graded sanding exercise with the variable of angle and velocity was shown to provide valuable data on pulmonary and cardiometabolic functions and to be safely and effectively used in occupational therapy in elderly patients with CVA.
