Comparative Study
Intrathecal drug delivery for treatment of chronic low back pain: report from the National Outcomes Registry for Low Back Pain.
To obtain data on patient demographics, clinical practices, and long-term outcomes for patients with chronic low back pain treated with implantable drug-delivery systems. ⋯ Current clinical practices related to trialing of drug-delivery systems resulted in the majority of patients successfully trialed. At 12-month follow-ups, implanted patients experienced reductions in numeric back and leg pain ratings, improved Oswestry scores, and high satisfaction with the therapy.

Multicenter Study Comparative Study
A low back-specific version of the SF-36 Physical Functioning scale.
A prospective repeated measures design was used to produce a back-specific version of the Short Form-36 Physical Functioning scale (SF-36 PF) by Rasch analysis of a pool of items from the SF-36 PF, Oswestry Disability Questionnaire, and the Quebec Back Pain Disability Scale. ⋯ The Low-Back SF-36 PF18 comprises the 10-item SF-36 PF scale and four items each from the Oswestry and Quebec back pain questionnaires. The possible total score ranges from 0 to 100, with a higher score indicating better function. The new scale appears to offer advantages over the use of the original scale for the assessment of functioning in patients with low back pain.

Clinical Trial
Pain-related fear, lumbar flexion, and dynamic EMG among persons with chronic musculoskeletal low back pain.
The purpose of this study was to examine the relationship between pain-related fear, lumbar flexion, and dynamic EMG activity among persons with chronic musculoskeletal low back pain. It was hypothesized that pain-related fear would be significantly related to decreased lumbar flexion and specific patterns of EMG activity during flexion and extension. ⋯ Pain-related fear is significantly associated with reduced lumbar flexion, greater EMG in full flexion, and a smaller FRR. The relationship between pain-related fear and EMG during flexion and extension appears to be mediated by reduced lumbar flexion. These results suggest that pain-related fear is directly associated with musculoskeletal abnormalities observed among persons with chronic low back pain, as well as indirectly through limited lumbar flexion. These musculoskeletal abnormalities as well as limited movement may be involved in the development and maintenance of chronic low back pain. In addition, changes in musculoskeletal functioning and flexion associated with pain-related fear may warrant greater attention as part of treatment.

Randomized Controlled Trial Clinical TrialThe effectiveness of relaxation acupoint stimulation and acupressure with aromatic lavender essential oil for non-specific low back pain in Hong Kong: a randomised controlled trial.
To assess the effect of acupoint stimulation with electrodes combined with acupressure using an aromatic essential oil (lavender) as an add-on-treatment on pain relief and enhancing the physical functional activities among adults with sub-acute or chronic non-specific low back pain. ⋯ Our results show that 8-sessions of acupoint stimulation followed by acupressure with aromatic lavender oil were an effective method for short-term LBP relief. No adverse effects were reported. To complement mainstream medical treatment for sub-acute LBP, the combined therapy of acupoint stimulation followed by acupressure with aromatic lavender oil may be one of the choices as an add-on therapy for short-term reduction of LBP.

Comparative Study
Smoking status and psychosocioeconomic outcomes of functional restoration in patients with chronic spinal disability.
Studies have revealed smoking to have a negative impact on spinal surgery. It is assumed that this is the result of the negative impact of nicotine on revascularization of damaged tissue. However, there is a paucity of research on the role of smoking with regard to nonsurgical rehabilitation, but there exists a clear bias for believing that smoking is strongly associated with poor socioeconomic and psychosocial outcome. ⋯ Contrary to popular belief, CDWRSD patients who smoke do not differ significantly in socioeconomic or psychosocial outcomes relative to those who do not. Although this study does indicate that those who smoke more evidence lower rehabilitation completion rates, those who completed the program had identical 1-year posttreatment outcomes of socioeconomic importance except in retraining work at year end as those who did not smoke. Smokers had slightly higher posttreatment self-reported pain and disability ratings mixed and limited. Overall, there is evidence for the widely held belief that smoking negatively affects tertiary rehabilitation.
