A comparative effectiveness trial indicates that dorsal root ganglion stimulation provided a higher rate of treatment success with less postural variation in paresthesia intensity compared to spinal cord stimulation.

PRFD of the lateral branch of the medial branch of L4, posterior primary rami of L5, and lateral branches S1 and S2 is an effective treatment for some patients with SIJ pain unresponsive to other forms of therapy.

Little is known about the impact of thermoregulatory demands on cardiovascular and psychological responses of firefighters during firefighting activities. This study examined selected responses to a training drill in different thermal environments. Male firefighters (n = 16) were randomly assigned to perform a simulated ceiling overhaul task for 16 min in either a neutral (13.7 degrees C) or hot (89.6 degrees C) condition while wearing standard firefighting turnout gear. Physiological and psychological measures were assessed before, after 8 min and 16 min of firefighting activity, and following a 10-min recovery period. The variables assessed included heart rate (HR), tympanic temperature (Ttymp), lactate level (LAC), blood glucose level, ratings of perceived exertion (RPE), perceptions of respiration, thermal sensations (TS) and state anxiety (SA). Significant increases were seen for HR, Ttymp, LAC, RPE and SA, with the increases being much greater following the hot condition. Recovery was significantly slower following work in the hot condition. These findings suggest that the addition of a live fire (a common situation for firefighters) contributes to increased cardiovascular and psychological strain at a standardized workload.
