Reference Arm for Blood Pressure Measurement in Stroke Survivors

Background: Averting recurrent stroke among stroke survivors requires a choice of the appropriate arm for blood pressure (BP) measurement, especially among high - risk survivors. Objectives: This study aimed at determining the appropriate arm for BP measurement in stroke survivors. Methods: This cross sectional study comprised of 100 volunteer and willing stroke survivors enrolled using the convenient sam-plingtechniquefrom2publichospitalsinMaiduguri,Nigeria.

Student’s t - test for independent samples was used to compare mean BP between unaffected and affected arms of the participants. Results: Mean age and age range of the participants in years were 53.8 + 17.7 and 20 to 90, respectively. Participants that had had a stroke within the previous 7 months accounted for 69.0% of cases. Spastic stroke constituted 71%. Sides of the body afflicted with stroke were equally distributed. A significant difference (p = 0.017) existed in blood pressure between unaffected and affected arms of stroke survivors. Conclusions: Health workers involved in the management of stroke patients were advised to take blood pressure measurement from both the affected and non-affected arms; the arm with the higher value should be taken as the reference arm.
