Blood pressure response to acupuncture in a population at risk for autonomic dysreflexia.
OBJECTIVE
To determine whether acupuncture can lead to autonomic dysreflexia (AD) when used to treat chronic pain in individuals with spinal cord injury (SCI).


METHODS
Acupuncture analgesia study.


METHODS
Medical rehabilitation research center.


METHODS
Fifteen participants with post-SCI chronic pain who were at risk for AD (ie, SCI at or above T8).


METHODS
Half-hour acupuncture treatment sessions twice a week for 7.5 weeks, for a total of 15 treatments. Acupuncture needles were inserted both above and below the patient's spinal lesion level. Blood pressure (BP) was measured before and after acupuncture treatments.


METHODS
Systolic BP (SBP) and diastolic BP (DBP). Participants monitored for signs and symptoms of AD.


RESULTS
On average, SBP and DBP remained stable across all 15 treatment sessions. None of the participants experienced any symptoms of AD. However, examination of individuals' BP readings indicated acute elevations (20 mmHg or higher) in SBP for 3 of the 15 participants.


CONCLUSIONS
Although none of the 15 participants who were at risk for developing AD developed symptoms consistent with this diagnosis, 3 displayed an acute elevation in SBP, suggesting a pattern of imminent AD. Comorbid hypertension appeared to contribute to the elevation in 1 patient. Therefore, careful monitoring of patients with SCI or hypertension during acupuncture treatments is advisable.
