Seven elite boardsailors reporting nonradiating low back pain without leg pain during sailing volunteered for detailed examination. In these subjects, the onset of pain was limited to those occasions when sailing positions were held for a significant period of time, e.g., close hauled sailing or in light winds. No pain was described at any other time. The determination of possible antecedent factors was based on the results of clinical assessment, radiological evaluation, and computer tomography (CT) scanning. Apart from limited flexibility in some subjects, the clinical examination of these athletes was normal; CT changes in this group were limited to disc protrusions and bulges, and pars interarticularis defects. Despite the small number of subjects in the present report, it appears that the frequency of these problems exceeds that in the normal population. It may be possible to suggest that risk factors such as body position during prolonged sailing, particularly under light wind conditions without a harness, and limited flexibility may be associated with the radiological findings and may be implicated in the presence of low back pain, although further investigations appears warranted.

Eighty-six patients with refractory chronic low back pain were randomly assigned to receive either facet joint injection or facet nerve block, using local anaesthetic and steroid. There was no significant difference in the immediate response. The duration of response after facet joint injection was marginally longer than after facet nerve block (P less than 0.05 1 month after infiltration), but for both groups the response was usually short-lived; by 3 months only 2 patients continued to report complete pain relief. Patients who had complained of pain for more than 7 years were more likely to report good or excellent pain relief than those with a shorter history (P less than 0.005), but no other clinical feature was of value in predicting the response to infiltration. Facet joint injections and facet nerve blocks may be of equal value as diagnostic tests, but neither is a satisfactory treatment for chronic back pain.

Forty-five low back pain patients were randomly assigned to either a standard inpatient rehabilitation program or the standard program with additional psychological components. The standard program emphasized education, support, and physical reconditioning through exercise. Patients receiving the psychological program were given additional training in relaxation and other coping skills and received contingent reinforcement for exercise. Both programs included reduction of medication intake and an emphasis on family involvement after discharge. Measures of functional status were taken prior to the program, at discharge from the 3-week inpatient program, and at a 6-month follow-up appointment. These data revealed that patients improved their overall functioning at discharge and maintained these gains at the follow-up assessment. A similar pattern of findings was obtained for self-reported pain and interference. Furthermore, 81% of the patients had returned to work or were engaged in active job retraining by the follow-up. Using a conservative measure of full-time return to the same or an equivalent job, 57% were employed by the follow-up. Patient improvement, however, was not differentially affected by treatment group assignment, suggesting that the psychological treatment failed to add to the effectiveness obtained by the standard rehabilitation program. Results are discussed in the context of improving patient outcomes from rehabilitation for low back pain.

This study examined the reliability and validity of the Roland scale (taken from the Sickness Impact Profile: SIP) as a measure of dysfunction among chronic pain patients. One hundred forty-four subjects completed the SIP when they were screened for admission to an inpatient pain management program. One hundred sixteen subjects were subsequently re-administered the SIP at admission to inpatient treatment. A 3-month post-treatment administration of the SIP was performed for 52 of these subjects. Roland scale scores were calculated from the SIP for each patient. Test-retest stability coefficients indicated that the SIP Roland scale was generally as reliable as the SIP Total, Physical, and Psychosocial scale scores. Consistent with previous research, correlational analyses indicated that the SIP Roland scale is strongly associated with the SIP Physical but not the SIP Psychosocial scale. The SIP Roland scale and the other SIP scales demonstrated similar sensitivity to changes associated with multidisciplinary inpatient treatment for chronic pain. Finally, the pattern of relationships between the SIP Roland scale and several pain-related measures supported the concurrent validity of the SIP Roland scale. The results of the analyses were very similar for patients presenting with and without low back pain. The study supports the reliability and validity of the SIP Roland scale items for assessing dysfunction of chronic pain patients with pain in sites other than the low back as well as those with low back pain.

The effect of the presence of either chronic or acute clinical pain on pain threshold and on the nociceptive flexion reflex (RIII) threshold was studied. The experimental pain sensation and the flexion reflex were evoked by trains of short electrical pulses. It was hypothesized that both kinds of clinical pain would be able to induce 'diffuse noxious inhibitory controls' (DNIC) and thereby raise the 2 experimental thresholds. Patients with chronic low back pain, patients with postoperative pain from oral surgery, and pain-free subjects were tested in 3 conditions: during baseline, after i.v. administration of a placebo, and after i.v. administration of naloxone. In comparison with 2 pain-free control groups, the 2 pain groups had a significantly higher pain threshold in all conditions. However, the RIII threshold was not significantly elevated in chronic or acute pain patients compared to controls. Naloxone had no effect on the RIII or pain threshold in any of the groups. It is concluded that the increased pain threshold which is frequently found in chronic pain patients, and which could be confirmed in the present study, does not result from a DNIC effect. The adaptation level theory offers an alternative explanation. Also, the acute postoperative pain in this study did not seem to induce DNIC. Because other forms of acute pain have been found to be effective in activating DNIC, future research should establish which pains are and which pains are not effective.

The functional consequences on everyday living which result from chronic low back pain commonly require services which are difficult to access. This deficiency in meeting the needs of these patients is partially explained by inadequacies in clinical assessment. Medical evaluation may be exhaustive, but frequently the assessment of physical and psycho-social dysfunction at the personal and family level is inadequate. In low back pain, as with most chronic ailments, there is no agreed-upon taxonomy of the functional consequences of the disorder upon which to establish a comprehensive clinical appraisal. In this paper a taxonomy is presented for the impairments, disabilities and handicaps which result from chronic low back pain. The taxonomy has been based on data from a survey of 74 individuals with low back pain and is structured generally according to the International Classification of Impairments, Disabilities and Handicaps (WHO 1980). The taxonomy is proposed as a conceptual framework and vocabulary for both clinical practice and research. The taxonomy is not a measurement instrument nor does it indicate the frequency of occurrence of disabilities. A classification is basic to the advancement of scientific understanding, and usage of a standard vocabulary such as this plays an important role in establishing a responsive health service capable of meeting the needs of the population with chronic low back pain.

Rheumatic manifestations are common and varied in infective endocarditis. We performed a retrospective case analysis on 87 patients with 93 episodes of infective endocarditis admitted to Flinders Medical Centre over an 11 year period (1980-1990). Disabling musculoskeletal symptoms and signs were documented in 22 (25%) of the patients. Thirteen patients developed severe or moderately severe low back pain during their illness, two with radiological evidence of a septic discitis or vertebral osteomyelitis. Two patients developed polyarthralgia/arthritis, four had septic arthritis (all with acute Staphylococcus aureus endocarditis), three developed severe loin pain, two acute gout, two had severe buttock pain and sacroiliac joint tenderness and two each developed disabling jaw/facial pain, neck/scapular pain and flank pain respectively. Five patients presented initially to the orthopaedic or rheumatological unit for management of their musculoskeletal symptoms. Four of seven patients with Streptococcus bovis endocarditis demonstrated prominent low back pain supporting a previously noted association between this organism and back symptoms. Furthermore, in one patient who had three separate episodes of endocarditis involving three different organisms, florid back symptoms were only seen in the infective episode involving Streptococcus bovis.

An unselected sample of outpatient subjects (n = 330) with localized nonspecific low back pain (LBP) was studied. Investigation consisted of clinical assessment, physical examination, and psychiatric interview based on the DSM-III classification. A psychiatric disorder, according to the DSM-III criteria (axis I) was found in 41% of the subjects. Multiple correspondence analysis and cluster analysis were used to objectively identify clinical subtypes without preconceived theoretical models. Correspondence analyses suggested the existence of a 'psychological pain' syndrome consisting of several of the following symptoms: diffuse back pain, impossibility to assess intensity of pain on a pain scale, aggravation of pain by changing climate, by domestic activities or by psychological factors and dysesthesias in the back. Cluster analysis provided support for a four-group classification of low back pain, which may be interpreted through the relationships between psychological disturbances and the LBP clinical features. The results call for further investigation of the complex relationship between psychological disturbances and back pain. However, clinicians must be aware of the interest of a minimal psychiatric assessment in low back pain patients: psychiatric disorders frequently appear in these patients and an appropriate treatment of the psychiatric syndrome may reduce back pain.

Most patients with chronic low back pain associate strenuous physical activities with increased pain. This association can cause avoidance of those activities believed to cause intolerable discomfort. This study explored the relationship of performance of physical activities with self-reported pain measures in 40 consecutive patients with disabling low back pain (mean duration 17 months) during a functional restoration rehabilitation program (mean treatment period 7 weeks). Evaluations were performed at initial presentation and at program completion. Measures included quantification of performance on eight physical tests assessing flexibility, lifting capacity and endurance. Before physical testing patients were asked to complete a pain analog scale, a quantified pain drawing, and a rating of the pain anticipated to result from the performance of each physical test. Results showed that pain measures did not generally correlate with measured physical performance. At completion of treatment, significant improvement in performance on all physical tests was found, but these were not associated with consistent changes in pain measures. These results demonstrate that subjects with chronic low back pain can increase their physical performance abilities within their same pain experiences. Medical recommendations for subjects' involvement in physical activities should not be based solely on the reported association of pain with those activities.

This article reports a case of joint dysfunction of the proximal tibiofibular joint that produced knee, thigh and low back pain of 5 yr duration. An injury of a simple nature apparently caused the onset of symptoms. Manipulation of the proximal tibiofibular joint resulted in immediate and dramatic relief of symptoms. This case illustrates how a relatively minor incident can result in longstanding pain and disability. Examination and treatment procedures for the proximal tibiofibular joint dysfunction are described.
