Transcutaneous nerve stimulation: its significance and applications in podiatry.

In summation, the neuranatomy and neurophysiology of pain have been presented. Three of the classical theories of pain transmission were also discussed, these being the specificity, pattern, and gate control theories. The gate control theory postulates that stimulation of large diameter sensory nerve fibers blocks pain sensation at the level of the substantia gelatinosa in the dorsal horn of the spinal cord. This theory is used as the basic explanation for the function of the TNS, a device that can control pain by stimulation of the skin through surface electrodes. TNS stimulation appears to be most efficacious when the electrodes are placed either directly over or just proximal to the painful region. Podiatric application appears to lend itself quite naturally to TNS therapy. Several surgical and nonsurgical cases were presented where TNS therapy was employed and in this preliminary study approximately a 63% improvement in pain state was shown. We believe this modality is useful for patients who should limit their intake of analgesic medications, whether they are medically compromised, allergic to various pain medication, or simply are highly intolerant to pain. TNS is also useful in patients who do not respond well to the more traditional and conventional podiatric treatments. Our study illustrates TNS to be efficacious in pain states of a surgical, chronic or acute nature and even pain secondary to systemic disease. It should be noted that TNS is not curative, per se, but is a useful adjunct in the therapeutic regime. This form of therapy, although not without hazard, is relatively safe and easy to use, and although it is not the answer to all pain states, it is highly recommended when applicable.

A comparison of weightbearing pressures in various postoperative devices.

Currently, there are a multitude of computerized gait analysis systems to evaluate weightbearing patterns in the foot. The following study utilizes the F-Scan System of foot pressure analysis. This system was applied to evaluate plantar pressures as they occur in various postoperative shoe gear and to determine which devices are most clinically beneficial in ambulatory surgery. A pressure sensor recorded plantar pressures in 20 feet wearing various types of postoperative shoe wear. Initially, a stockinette was used to simulate barefoot pressure, followed by a wooden postoperative shoe, a Darco postoperative shoe, a Darco closed postoperative shoe, a Darco "softie," a Darco wedge, an Equalizer Premium Walker, an Equalizer Low Top Walker, and an Aircast. The results demonstrated that the Equalizer Premium Walker was most efficient in reducing forefoot pressures, while the postoperative surgical shoes had variable results, noticeably with several increases in pressure being recorded.

Raymond L. Nimmo and the evolution of trigger point therapy, 1929-1986.

Dr. Raymond L. Nimmo (1904-86) was the definitive chiropractic pioneer in the now widely accepted field of soft tissue and trigger point therapy. This article explores how Nimmo was able to make the radical conceptual leap from moving bones to working with muscles that move the bones. Also discussed are the neurophysiological explanations that Nimmo evolved in the 1950s for the trigger point phenomenon, formulations that are still regarded as highly sophisticated half a century later. Finally, the article describes how Nimmo, with a basic chiropractic education absent much of the background in the biological and physical sciences of today's preparation, was able to combine his clinical experiences and intellectual formulation to arrive at a theory that became widely accepted.
