A psychophysical analysis of acupuncture analgesia was carried out in which low back pain patients made visual analogue scale (VAS) responses both to their chronic pain and to different levels of experimental heat pain (5 sec exposures to 43-51 degrees C) before and after electroacupuncture. VAS (sensory) responses to chronic pain, direct temperature matches to chronic pain, and VAS (sensory) responses to experimental pain were reduced in an internally consistent manner 1-2 h after treatment. The magnitude of this analgesic response was similar for dermatomes within the region of chronic pain and acupuncture needle placement (lower back) as well as for dermatomes remote from needle placement and chronic pain (forearm). ⋯ VAS sensory and VAS affective analgesic responses to electroacupuncture treatment showed a delayed onset (1-24 h) to maximum effect and a duration of 10-14 days. Cumulative sensory and affective analgesic effects were observed at the end of 4 months of biweekly acupuncture treatments. The results of this analysis reveal the unique spatial and temporal properties of electroacupuncture analgesia and the extent to which it is mediated by at least two different mechanisms.

ReviewLow back pain. Evaluation and treatment in the emergency department setting.
The author outlines the most common clinical syndromes causing back pain, including degenerative disc disease, disc herniation syndrome, and cauda equina syndrome. Also discussed are specific guidelines regarding the need for immediate orthopedic and neurosurgical consultation or admission to the hospital.

Comparative Study
Industrial low-back pain. A prospective evaluation of a standardized diagnostic and treatment protocol.
This investigation applied a diagnostic and treatment protocol to two groups of industrial workers: 5,300 employees at Potomac Electric Power Company ( PEPCO ) for two years and 14,000 United States Postal Service workers for one year. An "active" system in which patients were evaluated weekly was implemented at the power company, and a "passive" system in which patients were seen only once was instituted at the U. S. ⋯ S. Postal Service demonstrated a decrease in the number of low-back pain patients (41%), in days lost from work (60%), and in financial costs (55%). These results, along with our observations about the study, led us to the following conclusions: (1) Good medicine leads to cost savings in treating industrial low-back pain. (2) Use of a standardized medical approach and nomenclature is necessary and practical, for consistent care. (3) A good record keeping system is essential to perform useful medical analyses for identifying scientific problems. (4) Unbiased medical surveillance leads to changes in behavior of both treating physicians and patients. (5) The outcome for most low-back pain patients in industry is not as grim as previously perceived if their medical management is approached in an organized manner.

Patient evaluation of a cognitive behavioral group program for patients with chronic low back pain.
Traditional approaches to curing patients with chronic benign pain have had only limited success. Rehabilitation becomes therefore more important and in recent years management programs have been developed to achieve this goal. This study was based on the hypothesis that a program can be more effective with its structure according to the comments of patients with respect to the various components of the program. After testing this hypothesis we conclude that such subjective evaluation of treatment is an important factor which merits receiving more attention than previous work has suggested.
