Long-term follow-up of a randomized clinical trial assessing the efficacy of medication, acupuncture, and spinal manipulation for chronic mechanical spinal pain syndromes.

OBJECTIVE: To assess the long-term benefits of medication, needle acupuncture, and spinal manipulation as exclusive and standardized treatment regimens in patients with chronic (>13 weeks) spinal pain syndromes. STUDY DESIGN: Extended follow-up (>1 year) of a randomized clinical trial was conducted at the multidisciplinary spinal pain unit of Townsville's General Hospital between February 1999 and October 2001. PATIENTS AND METHODS: Of the 115 patients originally randomized, 69 had exclusively been treated with the randomly allocated treatment during the 9-week treatment period (results at 9 weeks were reported earlier). These patients were followed up and assessed again 1 year after inception into the study reapplying the same instruments (ie, Oswestry Back Pain Index, Neck Disability Index, Short-Form-36, and Visual Analogue Scales). Questionnaires were obtained from 62 patients reflecting a retention proportion of 90%. The main analysis was restricted to 40 patients who had received exclusively the randomly allocated treatment for the whole observation period since randomization. RESULTS: Comparisons of initial and extended follow-up questionnaires to assess absolute efficacy showed that only the application of spinal manipulation revealed broad-based long-term benefit: 5 of the 7 main outcome measures showed significant improvements compared with only 1 item in each of the acupuncture and the medication groups. CONCLUSIONS: In patients with chronic spinal pain syndromes, spinal manipulation, if not contraindicated, may be the only treatment modality of the assessed regimens that provides broad and significant long-term benefit.

Symptomatic protocols for adult tethered cord syndrome.

Diagnosis of tethered cord syndrome (TCS) is complicated because anatomical information is not adequate for this task. For example, recent studies have shown that the combination of an elongated cord and a thick filum terminale, demonstrated by MRI or at operation, is no longer an essential feature for the diagnosis of TCS. For TCS diagnosis, emphasis should rather be on its characteristic symptomatology and accentuated by postural changes, since TCS is a functional disorder of the lumbosacral spinal cord. In this report, the authors present the list of signs and symptoms pertinent to TCS in adult and late teenage patients to serve as a diagnostic means.

Chronic spinal pain: a randomized clinical trial comparing medication, acupuncture, and spinal manipulation.

STUDY DESIGN: A randomized controlled clinical trial was conducted. OBJECTIVE: To compare medication, needle acupuncture, and spinal manipulation for managing chronic (>13 weeks duration) spinal pain because the value of medicinal and popular forms of alternative care for chronic spinal pain syndromes is uncertain. SUMMARY OF BACKGROUND DATA: Between February 1999 and October 2001, 115 patients without contraindication for the three treatment regimens were enrolled at the public hospital's multidisciplinary spinal pain unit. METHODS: One of three separate intervention protocols was used: medication, needle acupuncture, or chiropractic spinal manipulation. Patients were assessed before treatment by a sports medical physician for exclusion criteria and by a research assistant using the Oswestry Back Pain Disability Index (Oswestry), the Neck Disability Index (NDI), the Short-Form-36 Health Survey questionnaire (SF-36), visual analog scales (VAS) of pain intensity and ranges of movement. These instruments were administered again at 2, 5, and 9 weeks after the beginning of treatment. RESULTS: Randomization proved to be successful. The highest proportion of early (asymptomatic status) recovery was found for manipulation (27.3%), followed by acupuncture (9.4%) and medication (5%). Manipulation achieved the best overall results, with improvements of 50% (P = 0.01) on the Oswestry scale, 38% (P = 0.08) on the NDI, 47% (P < 0.001) on the SF-36, and 50% (P < 0.01) on the VAS for back pain, 38% (P < 0.001) for lumbar standing flexion, 20% (P < 0.001) for lumbar sitting flexion, 25% (P = 0.1) for cervical sitting flexion, and 18% (P = 0.02) for cervical sitting extension. However, on the VAS for neck pain, acupuncture showed a better result than manipulation (50% vs 42%). CONCLUSIONS: The consistency of the results provides, despite some discussed shortcomings of this study, evidence that in patients with chronic spinal pain, manipulation, if not contraindicated, results in greater short-term improvement than acupuncture or medication. However, the data do not strongly support the use of only manipulation, only acupuncture, or only nonsteroidal antiinflammatory drugs for the treatment of chronic spinal pain. The results from this exploratory study need confirmation from future larger studies.

Patient satisfaction, characteristics, radiology, and complications associated with attending a specialized government-funded multidisciplinary spinal pain unit.

OBJECTIVE: To prospectively document the satisfaction of a random sample of patients attending a specialized multidisciplinary spinal pain unit in the Australian public health care system and to collect associated data on patient characteristics, radiological findings, treatment modalities used, and any significant complications. Design and setting Spinal pain syndrome patients attended the specialized Multidisciplinary Spinal Pain Unit at Townsville General Hospital and the Kirwan Community Health Centre (Queensland, Australia) for diagnosis and management (ie, chiropractic spinal manipulation, medication, or needle acupuncture). A patient satisfaction questionnaire was sent to a random sample of patients in this Queensland Government funded service that was approved by the health authority's Ethics Committee. RESULTS: A total of 1775 new patients (949 men, 826 women; aged 10 to 91 years; average age = 43 years) visited the unit. Medical referral accounted for 40% of patients, chiropractic for 2%, osteopathy for 1%, and other referrals for 0.7%; 40.3% were self-referred and 16% were specifically referred for a medicolegal consultation and examination following work-related or motor vehicle accident injuries. Thirty-nine patients (2.2%) were found to have acute pain (< 28 days). Of 941 patients who could accurately recall when symptoms first began, 69 (7.3%) presented with subacute pain (4 to 12 weeks duration), and 872 (92.7%) presented with chronic spinal pain syndrome (>12 weeks duration). Following extensive investigations, 1474 patients (83%) had radiologically identifiable abnormalities, including osseous or soft tissue anomalies. There was only 1 significant complication (pneumothorax) out of 7831 acupuncture treatment sessions, representing 0.01% of patients and 0.006% of a total of 16,936 examinations and treatments administered at the unit. The patient satisfaction questionnaire resulted in an extremely high satisfaction score. CONCLUSION: A public hospital or community health center based specialized spinal pain syndrome unit is useful for referring clinicians who wish to obtain a further opinion for challenging spinal pain syndrome patients in the lower socioeconomic group that cannot afford private health care.
