In a retrospective, controlled clinical study the life events of 35 patients suffering from chronic low back pain (LBP) and a matched sample of 23 patients with neurotic depression (ICD 300.4) were investigated. The pain patients formed two groups: 19 patients with definite organic diagnosis (IASP code 530.96) and 16 without (adequate) organic lesion (IASP code 510.99). Somatic diseases (other than LBP), injuries and operations, as well as psychic trauma (feelings of shame, narcissistic traumatisations and object losses) were defined and counted as documented in the patient's histories. ⋯ Object losses occur equally often in all groups, apart from the initial year, when depressive patients have to cope with even more losses than the others. These results are discussed considering the development of chronic pain syndromes, the influence of age and their consequences for models of illness. There is convincing evidence, that physical injury is neither a necessary nor a sufficient condition for the development of chronic pain and that chronic pain is in essence an emotional disease based on unresolved unconscious conflicts requiring psychotherapy.

Acupuncture is increasingly being used in Western medicine. In the present study the effect of acupuncture treatment was examined in 60 patients with chronic pain. The long-term success after 6 months was evaluated in 45 patients. ⋯ It appeared that the consumption of analgesics could be reduced significantly in patients in whom the treatment was successful. All patients had been treated before by several methods. Because of the small number of side-effects and the patients' high degree of acceptance as well as the success of the treatment, we consider acupuncture an effective method in the treatment of chronic pain.

Practitioners often rely on physiodiagnostic indicators to corroborate the hypothesis of a muscular origin of headache. Although these indicators have been widely applied, their reliability and validity have seldom been tested empirically in headache sufferers. In a controlled double blind study, two trained raters palpated muscle tension and latent and active myogeloses of the left and right trapezius and sternocleidomastoideus muscles and measured passive head rotation flexibility. ⋯ In keeping with the hypothesis, the various parameters of active myogeloses very clearly differentiated between the experimental groups. The hypothesis turned out not to be true for the parameters of head rotation flexibility. In subjects suffering from tension headache, no correlations could be found between the number of myogeloses of the right trapezius muscle and parameters recorded in long-term EMGs of this muscle, and no correlations could be found between the total number of myogeloses and the chronicity of headache.

A consecutive series of 98 patients presenting at an orthopedic outpatient clinic with chronic low back pain of at least 6 months' duration and with no organic findings (ruled out by clinical and radiological examination) were evaluated by means of a questionnaire which included the constructs "patient history," "pain-related restrictions," and "depression." Pain perception was evaluated with an adjective list revealing four main factors: two affective factors, i.e., "suffering from pain" and "anxiety," and two sensory factors, i.e., "acuteness" and "rhythmics of pain." The two affective factors (as against the sensory factors) subsequently influence the degree of pain intensity (measured with a visual analog scale), the patient's history and the patient's perceived impairment of daily life. Depression (von Zerssen scale) correlated with pain factors only when the whole range of pain factors was considered. The implications for treatment in patients with a high score for affective factors in the adjective list (indicator for a low success rate with traditional therapy) are discussed.

After the initial clinical reports of Shealy 1967 dorsal column stimulation (DCS) was first introduced in Germany by Krainick (Freiburg) and Winkelmüller (Hannover) in 1972. At first, the success rate in unselected patients was unsatisfactory. The results improved with careful patient selection and better technical equipment allowing preliminary testing procedures before definitive implantation. ⋯ The best indications and target group are cases with radicular low-back pain after failed back surgery, stump and phantom pain, pain states following partial lesions of brachial/lumbar plexus and peripheral nerves, sympathetic dystrophy and rest pain in peripheral vascular disease (PVD). Possible indications for SCS are pain after incomplete lesions of spinal cord or cauda equina, postherpetic neuralgia, sclerodermia and PVD. Failures must be expected in pain states related to progressive malignant disease and complete deafferentation after spinal lesions or root avulsion.
