There are discrepancy between MR findings and clinical presentations. The compressed cervical cord in patients of the spondylotic myelopathy may be normal on conventional MRI when it is at the earlier stage or even if patients had severe symptoms. Therefore, it is necessary to take a developed MR technique--diffusion tensor imaging (DTI)--to detect the intramedullary lesions. ⋯ ADC and FA values between lesions or the compressed cord and normal spinal cord of patients had a significant difference (both P < 0.01). FA value at C2/3 cord is the highest of other segments and it gradually decreases towards the caudal direction. Using single-shot spin echo EPI sequence and six non-collinear diffusion directions with b value of 400 s mm(-2), DTI can clearly show the intramedullary microstructure and more lesions than conventional MRI.

The original 'Örebro Musculoskeletal Pain Questionnaire' (original-ÖMPQ) has been shown to have limitations in practicality, factor structure, face and content validity. This study addressed these concerns by modifying its content producing the 'Örebro Musculoskeletal Screening Questionnaire' (ÖMSQ). The ÖMSQ and original-ÖMPQ were tested concurrently in acute/subacute low back pain working populations (pilot n = 44, main n = 106). ⋯ The six-component factor structure reflected the constructs originally proposed. The ÖMSQ can be substituted for the original-ÖMPQ in this population. Further research will assess its applicability in broader populations.

The Oswestry Disability Index (ODI) is one of the most widely used questionnaires that assess disability in patients with low back pain (LBP). Responsiveness is both an important psychometric property of an instrument and a key issue for clinicians when choosing suitable outcome measures. The objective of this study was to examine the responsiveness of the Chinese version of the ODI (ODI-Chinese) for subjects with chronic LBP following a physical therapy program. ⋯ The SRM of the ODI-Chinese was -1.2 in the improved group and -0.4 in the non-improved group. The area of the ROC curve for the ODI-Chinese was 0.77 (95% CI 0.66-0.89). Therefore, the Chinese version of the ODI is both responsive and appropriate for use in chronic LBP patients after conservative therapy.

Comparative Study Clinical Trial
Outcomes differ between subgroups of patients with low back and leg pain following neural manual therapy: a prospective cohort study.
The objective is to determine if pain and disability outcomes of patients treated with neural mobilisation differ for sub-classifications of low back and leg pain (LB&LP). Radiating leg pain is a poor prognostic factor for recovery in patients with LBP. To improve outcome, a new pathomechanism-based classification system was proposed: neuropathic sensitization (NS), denervation (D), peripheral nerve sensitization (PNS) and musculoskeletal (M). ⋯ The proportion of responders was significantly greater in PNS (55.6%) than the other three groups (NS 10%; D 14.3% and M10%). After adjusting for baseline differences, mean magnitude of improvement of the outcome measures were significantly greater in PNS compared to the other groups. Patients classified as PNS have a more favourable prognosis following neural mobilisation compared to the other groups.

The majority of women recover from pregnancy-related lumbopelvic pain within 3 months of delivery. Since biomechanical and hormonal changes from pregnancy are largely reversed by 3 months postpartum, consequently, it is assumed that other factors might interfere with recovery. Relative to the fear-avoidance model and with reference to previous studies, we chose to investigate some pre-decided factors to understand persistent lumbopelvic pain. ⋯ Pain intensity, HRQL and kinesiophobia explained 53% of postpartum disability due to lumbopelvic pain. In conclusion, one of three postpartum women still had some lumbopelvic pain and the impacts were equivalent irrespective of symptoms in lumbar or pelvic areas. The additional explanations of variance in disability by HRQL and kinesiophobia were minor, suggesting that pain intensity was the major contributing factor.
