Abstract

 

The medical records of 2239 patients (mean age=73 years) with established peripheral neuropathy (PN) were examined to determine whether treatment with MIRE was, in fact, associated with increased foot sensitivity to the Semmes Weinstein monofilament (SWM) 5.07 and a reduction in neuropathic pain. The PN in 1395 of these patients (62%) was due to diabetes. Prior to treatment with MIRE, of the 10 tested sites (5 on each foot), 7.1F2.9 were insensitive to the SWM 5.07, and 2078 patients (93%) exhibited loss of protective sensationdefined by Medicare as a loss of sensation at two or more sites on either foot. After treatment, the number of insensate sites on both feetdecreased to 2.4± 2.6, an improvement of 66%. Of the 2078 (93%) patients initially presenting with loss of protective sensation, 1106 (53%)no longer had loss of protective sensation after treatment ( P< .0001); 1563 patients (70%) also exhibited neuropathic pain in addition to sensory impairment. Prior to treatment with MIRE, pain measured on the 11-point visual analogue scale (VAS) was 7.2±2.2 points, despitethe use of a variety of pain-relieving therapeutic agents. After treatment with MIRE, pain was reduced by 4.8±2.4 points, a 67% reduction.Therefore, MIRE appears to be associated with significant clinical improvement in foot sensation and, simultaneously, a reduction inneuropathic pain in a large cohort of primarily Medicare aged, community-dwelling patients, initially diagnosed with PN. The quality of life associated with these two outcomes cannot be underappreciated.
