RESUMEN
OBJECTIVES: To investigate whether the blood pressure (BP) levels are similar between the paralyzed and unaffected arms or legs. METHODS: This study enrolled 236 post-stroke patients with hemiplegic paralysis. Simultaneous four-limb BP was measured using four automatic BP devices for three times, and the average was used as final value. The inter-arm difference (IAD) and inter-ankle difference (IAND) were the BP difference between the arms or ankles, respectively. The difference between maximal BP reading and minimal BP reading was calculated as â³BP to reflect the variation of three BP readings. RESULTS: The paralyzed arm had similar mean SBP (134.8 ± 18.7 vs. 135.1 ± 19.0 mmHg, NS) and DBP (79.5 ± 11.3 vs 78.1 ± 10.4 mmHg, NS) levels as compared with the unaffected arm. Similarly, the mean ankle SBP (143.6 ± 19.1 vs. 143.7 ± 18.6 mmHg, NS) and DBP (77.9 ± 17.7 vs. 75.8 ± 11.1 mmHg, NS) in the paralyzed legs were also similar to those in the unaffected legs. The detection rate of systolic IAD ≥10 mmHg was 5.9% and that for systolic IAND ≥15 mmHg was 20.3%. Meanwhile, â³SBP levels were similar between two arms or ankles. CONCLUSION: In the post-stroke patients with hemiplegic paralysis, the SBP and DBP levels of the paralyzed and unaffected arms or ankles were similar.
