Randomized Controlled Trial Multicenter Study
Repeatability of the six-minute walk test and relation to physical function in survivors of a critical illness.
The Six-Minute Walk Test (6MWT) is widely used as an outcome measure in exercise rehabilitation. However, the repeatability of the 6MWT performed at home in survivors of a critical illness has not been evaluated. ⋯ In survivors of a critical illness, the 6MWT in the home environment should be performed twice at each assessment to give an accurate reflection of change in exercise capacity over time. The SF-36 PF score was a strong indicator of 6-minute walk distance in early recovery from a critical illness.

Multicenter Study Comparative Study
Comparison of two methods for interpreting lifting performance during functional capacity evaluation.
Functional capacity evaluation (FCE) requires determination of effort by observation of effort indexes for performance interpretation. Waddell signs have been shown to be associated with decreased functional performance. Whether determination of effort by observational criteria and Waddell sign testing can be used interchangeably to interpret lifting performance is unknown. ⋯ In people with chronic nonspecific low back pain, Waddell sign testing and determination of physical effort by observational criteria should not be used interchangeably to interpret lifting performance during FCE.

Multicenter Study
Impact of pain reported during isometric quadriceps muscle strength testing in people with knee pain: data from the osteoarthritis initiative.
Muscle force testing is one of the more common categories of diagnostic tests used in clinical practice. Clinicians have little evidence to guide interpretations of muscle force tests when pain is elicited during testing. ⋯ Given that the spectrum of the sample was skewed toward mild or moderate symptoms and disease, the data suggest that isometric quadriceps muscle strength tests maintain their relationship with self-report or performance-based disability measures even when pain is elicited during testing.

Multicenter Study
Relationship between categorization with the STarT Back Screening Tool and prognosis for people receiving physical therapy for low back pain.
The STarT Back Screening Tool (SBT) was recently developed for primary care providers to use as a screening tool for subgrouping people with low back pain (LBP) on the basis of modifiable prognostic factors. The use of the SBT in physical therapy has not been described. ⋯ The SBT may provide important prognostic information for physical therapists.

Randomized Controlled Trial Multicenter Study
Examination of a clinical prediction rule to identify patients with neck pain likely to benefit from thoracic spine thrust manipulation and a general cervical range of motion exercise: multi-center randomized clinical trial.
A clinical prediction rule (CPR) purported to identify patients with neck pain who are likely to respond to thoracic spine thrust manipulation has recently been developed, but has yet to be validated. ⋯ The results of the current study did not support the validity of the previously developed CPR. However, the results demonstrated that patients with mechanical neck pain who received thoracic spine manipulation and exercise exhibited significantly greater improvements in disability at both the short- and long-term follow-up periods and in pain at the 1-week follow-up compared with patients who received exercise only.
