Multicenter Study
Validity of the Neck Disability Index and Neck Pain and Disability Scale for measuring disability associated with chronic, non-traumatic neck pain.
The purpose of this study was to evaluate the construct and content validity of the Neck Disability Index (NDI) and the Neck Pain and Disability Scale (NPAD) in patients with chronic, non-traumatic neck pain. Twenty patients (mean age=64.5 years) completed a patient-specific questionnaire, the Problem Elicitation Technique (PET), followed by the NDI and NPAD. Content validity was assessed by comparing the items of the NDI and NPAD with problems identified from the PET. ⋯ The NDI and NPAD scores were strongly correlated (r=0.86, p<0.01), while the correlation between the PET and the fixed-item questionnaires was moderate (NDI: r=0.62, p<0.01; NPAD: r=0.71, p<0.01). Both the NDI and the NPAD include most of the functional problems common to this patient group, and display good content validity. The PET is better able to evaluate the problems specific to the individual patient and is therefore measuring a somewhat different construct to the fixed-item questionnaires.

Comparative Study Clinical Trial
Reliability and validity of a palpation technique for identifying the spinous processes of C7 and L5.
The objective was to examine inter-tester reliability and validity of two therapists identifying the spinous processes (SP) of C7 and L5, using one predefined surface palpation procedure for each level. One identification method made it possible to examine the reliability and the validity of the procedure itself. Two manual therapists examined 49 patients (29 women). ⋯ The results indicated acceptable inter-therapist surface palpation agreement, but the chosen procedures did not identify the correct SP. This indicates that the procedures are not precise enough. Future reliability studies should test other non-invasive palpation procedures, both individually and in combination, and compare these with radiological investigation.

Clinical Trial
The short-term effects of thoracic spine thrust manipulation on patients with shoulder impingement syndrome.
The study was an exploratory, one group pretest/post-test study, with the objective of investigating the short-term effects of thoracic spine thrust manipulations (TSTMs) on patients with shoulder impingement syndrome (SIS). There is evidence that manual physical therapy that includes TSTM and non-thrust manipulation and exercise is effective for the treatment of patients with SIS. However, the relative contributions of specific manual therapy interventions are not known. ⋯ At 48-h follow-up, the NPRS change scores for Neer impingement sign, Hawkins impingement sign, resisted empty can, resisted external rotation, resisted internal rotation, and active abduction were all statistically significant (p<0.01). The reduction in the SPADI score was also statistically significant (p<0.001) and the mean GRCS score=1.4+/-2.5. In conclusion, TSTM provided a statistically significant decrease in self reported pain measures and disability in patients with SIS at 48-h follow-up.
