Eighteen patients with chronic low back pain (lbp) of muscle tension origin were given an EMG biofeedback training. Compared to seven controls they showed a significant decrease during training in muscle tension and subsequently in pain. However, at follow-up EMG levels dropped to the initial (high) level. Pain scores of patients with high pain decrements during training showed further improvement during follow-up, which was not the case with patients showing less substantial improvement. The importance of cognitions was discussed.

Compared self-concepts of three groups, medical patients, chronic low back pain patients and chronic head pain patients (N = 60) to determine (1) whether chronic pain patients have self-perceptions that differ from other medical patients; (2) whether changes in self-perception are limited to physical attributes and capacities; and finally (3) whether persons who suffer different types of chronic pain would have differing self-concepts. Significantly lower self-concepts were obtained from groups of head pain and low back pain patients. Self-concept patterns for the two pain groups were quite similar with the exception of two self-concept components that were significantly lower for the head pain group. Differences were explained in terms of loss of many normal functions and disruption of normal life-styles. Implications for treatment of pain patients and for training of health professionals were discussed.

A multivariate clustering procedure was used to identify replicable, homogeneous MMPI profile subgroups among three independent cohorts of male (N = 233) and female (N = 315) low back pain ((LBP) patients. Three subgroups were replicated across all male cohorts and four subgroups were replicated across all female cohorts. Multiple discriminant analysis showed that for both male and female patients between-subgroup variability was significantly greater than within-subgroup variability. The results suggest that LBP patients may not be solely characterized by MMPI profiles featuring the "conversion V" configuration. Examination of the profile subgroups also suggests there may be distinct, pain-related, behavioral attributes associated with each subgroup which might have important implications for practitioners' choice of treatment modalities. Suggestions are made for research regarding the development of specific, optimal treatments for various LBP patient subgroups.

Preliminary findings are presented of a double-blind, crossover trial comparing the effects of traditional with placebo acupuncture in relieving chronic low back pain. 77 patients completed the study. Following initial assessment and baseline readings, patients had a 4-week course of active or placebo treatment given twice weekly. After a 4 week rest period patients received the alternate treatment, using the same time schedule. A 4 week follow-up period completed the trial. Using visual analogue scale readings as a measure of pain there was no cumulative difference in pain reduction achieved by traditional as compared with placebo acupuncture treatment. Both groups achieved a 55% overall reduction in pain level at the end of the trial, compared with initial baseline readings.

To test the possibility of endorphin release in clinical pain states naloxone was given, alternate with saline, in a double-blind study to 10 patients with chronic neuralgia or low back pain. There was no significant alteration of the levels of spontaneous pain or heat pain thresholds. The results suggest that the endorphin system does not offer protection of any importance in chronic pain.

Ninety-four patients with non-specific lumbar pain referred to hospital rheumatology and orthopaedic clinics participated in a double-blind controlled trial comparing mobilisation and manipulation with placebo physiotherapy. Results were assessed immediately after the tratment course, two months later, and at one year. Many patients showed improvement, but in contrast to a study on general-practitioner patients with nonspecific back pain no definite advantage could be associated with mobilisation and manipulation. The benefits of mobilisation and manipulation for low back pain are probably restricted to hastening recovery in patients likely rapidly to improve spontaneously. Hence patients whose severity and duration of symptoms warrant specialist referral are less likely to benefit from the technique.

Patients with undiagnosable low back pain have been observed to differ from patients with proven low back pain in their clinical description of pain and in their psychological status. More variable and diffuse pain qualities are emphasized in their clinical reports and more psychological disturbance characterizes them as a group, suggesting an association between pain expression and psychological disturbance. One hundred and two patients with low back pain were administered a standardized pain questionnaire to determine more systematically the association between pain expression and psychological disturbance in patients with and without demonstrable organic disease. Patients with psychological disturbance differed significantly from patients without psychological disturbance in the following ways. They used more words in their description of pain, distributed these words over more pain factors, and endorsed significantly more pain of the affective and skin pressure variety. The results underscore previous clinical impressions and suggest that patients without either organic or psychological findings may be cases of undiagnosed organic disease.

Relationships of four demographic variables and five affective variables to eight attributes of low back pain were investigated in 251 patients by stepwise, multivariate analysis. The demographic variables are age, sex, race, and education. The affective variables are state anxiety, trait anxiety anxiety, hostility, and depression. Seven of the pain variables are from the factorially derived Low Back Pain Questionnaire. The eighth pain variable is a self-estimate of intensity. Relationships among demographic and pain variables are small and unsystematic. Hostility has a small, systematically inverse relation to pain variables, supporting theories relating low back pain to inhibition of anger. Anxiety has a small positive relationship, and depression has no relationship to pain variables. In general, the small relationships indicate that the Low Back Pain Questionnaire provides descriptions of pain that are not confounded by social characteristics or current emotional states of patients.

Twenty patients with low back pain were selected for treatment with acupuncture. Four standard acupuncture loci and a standard regime were used. The results were analyzed after a follow-up of 12 months. Initially, 16 patients responded favorably to the treatment while 4 did not respond at all. The degree of cure was not uniform. Instead they varied from complete cure in 4 to varying degrees of alleviation of pain in the rest. Recurrence or acute exacerbation of symptoms occurred in 13 of the 20 patients. Acupuncture was given to 11 of these patients and the results of treatment similated the initial course of acupuncture.

The neuronal systems involved in low back pain are first described in a functional anatomical review and then an attempt is made to work out the special functional structure data which seem to be decisive for the origin and localization of low back pain and ischialgia. Low back pain may arise as a deep pain through stimulation of the nociceptive afferents in the musculature and supporting tissues and as a neural pain through irritation of nociceptive nerve fibers within the innervation area of the lumbosacral plexus. The nociceptive influx from the viscera only elicits pain in the rarest cases, however, it often has a conductive influence. Skeletal muscle plays a special role here, along with the sensory supply to the vertebral motor segment through the spinal nerve and the particular innervation scheme of the lumbosacral plexus caused by the limb budding.
