BACKGROUND AND PURPOSE The relationship between functional capacity evaluation (FCE) data and work disability has not been studied. The validity of FCE testing results in terms of subsequent return to work (RTW) was the focus of this exploratory study. SUBJECTS AND METHODS Six hundred fifty adults of working age were evaluated as part of a standardized(More)
BACKGROUND The QuickDASH, an abbreviated form of the Disabilities of the Arm, Shoulder and Hand Questionnaire, uses a graded-adjectives ordinal measurement response scale. In order to improve the sensitivity of the measure and to make it compatible with widely used measures of pain and disability, a visual analog scale version was developed. The present(More)
STUDY DESIGN A comparison of treatment of 412 patients with chronic back pain at two separate centers using the same treatment protocols and outcome measures. Outcome was defined by specific strength testing; Short Form-36 scores at intake, discharge, and 1-year follow-up; self-appraisal of improvement at discharge and in a 1-year follow-up; and reuse of(More)
This study investigated the test-retest reliability and validity of the isokinetic and gravity/inertia modes of the Lido Lift TM and the Progressive Lifting Capacity II test (PLC II). Maximum lifting capacity tests were performed in the isokinetic and gravity/inertia modes on the Lido Lift and with the PLC II with 29 healthy male subjects. Pearson(More)
The intra-test and test-retest reliability of the Spinal Function Sort was assessed in a multisite study involving 180 disabled subjects. The results of this study demonstrate the reliability of the instrument across a variety of sites. In addition, this study demonstrated both differences in absolute scores and a pattern of reactivity to the instrument(More)
Development of a self-report measure of activity limitation that combines measures of ability with necessity is described. The history of the Milliken Activities of Daily Living Scale (MAS) is traced, and the current measure is described. The test–retest reliability and concurrent validity of the MAS is studied. The MAS is found to have excellent(More)
Functional capacity evaluation is an important and widely available service provided by rehabilitation professionals, including many physical therapists. In the absence of agreed-upon professional standards, guidelines for practice have been developed. These guidelines provide a basis for the development of standards of practice which the authors believe(More)
OBJECTIVE To evaluate the effects of continuous low-level heat wrap therapy for the prevention and early phase treatment (ie, 0-48 h postexercise) of delayed-onset muscle soreness (DOMS) of the low back. DESIGN Two prospective randomized controlled trials. SETTING Outpatient medical facility. PARTICIPANTS Sixty-seven subjects asymptomatic of back pain(More)
The construct validity of the Hand Function Sort (HFS) was investigated in 126 adults of working age (65% male) with medical impairments. Principal components factor analysis identified one major factor and two minor factors, which was consistent with the findings of a subsequent Harris Image Analysis. A Kaiser Image Analysis identified seven factors,(More)
Development of a new pictorial activity and task sort and examination of its reliability and validity is described. The Multidimensional Task Ability Profile (MTAP) is the latest in a series of measures that use a combination of drawings and task descriptions in a self-report format to assess functional capacity. The MTAP is found to be reliable on a(More)
