BACKGROUND AND OBJECTIVES Physical function is an important measure of success of many medical and surgical interventions. Ability to adjust for comorbid disease is essential in health services research and epidemiologic studies. Current indices have primarily been developed with mortality as the outcome, and are not sensitive enough when the outcome is(More)
UNLABELLED The Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure was developed to evaluate disability and symptoms in single or multiple disorders of the upper limb at one point or at many points in time. PURPOSE The purpose of this study was to evaluate the reliability, validity, and responsiveness of the DASH in a group of diverse(More)
BACKGROUND The purpose of this study was to develop a short, reliable, and valid measure of physical function and symptoms related to upper-limb musculoskeletal disorders by shortening the full, thirty-item DASH (Disabilities of the Arm, Shoulder and Hand) Outcome Measure. METHODS Three item-reduction techniques were used on the cross-sectional(More)
BACKGROUND The role of bracing in patients with adolescent idiopathic scoliosis who are at risk for curve progression and eventual surgery is controversial. METHODS We conducted a multicenter study that included patients with typical indications for bracing due to their age, skeletal immaturity, and degree of scoliosis. Both a randomized cohort and a(More)
BACKGROUND The collection of population-based normative data is a necessary step in the process of standardization of eleven American Academy of Orthopaedic Surgeons (AAOS) musculoskeletal outcomes measures. These data serve as comparative normative scores with which to assess the effectiveness of treatment regimens in clinical practice settings and to(More)
Patients undergoing limb salvage surgery for bone and soft tissue sarcoma of the extremities experience significant physical disability as a result of life-preserving treatment. The existing health status measures do not adequately evaluate physical function from the patient's perspective. This paper presents the developmental studies item selection, of a(More)
In June 2000, The Journal introduced the quarterly Evidence-Based Orthopaedics section. This section introduces orthopaedic surgeons to recent randomized trials relevant to the practice of orthopaedic surgery published in forty-two journals other than The Journal of Bone and Joint Surgery. Structured abstracts of these studies are published along with(More)
The Activities Scale for Kids (ASK) is a self-report measure of childhood physical disability, that has excellent reliability (ICC = 0.97). The purpose of this study was to assess further the ASK's measurement properties. ASK questionnaires were completed by 200 children with musculoskeletal limitations (mean age, 10.1 years). Rasch analyses confirmed that(More)
A cross-sectional, community-based survey of a random sample of 1750 of 242,311 Medicare recipients was performed. The patients were at least sixty-five years old and had had a primary or revision knee replacement (either unilaterally or bilaterally) between 1985 and 1989. Three samples were surveyed separately: a national sample (to reflect the United(More)
Carboplatin clearance is correlated with glomerular filtration rate (GFR) and usually estimated with creatinine clearance using Cockcroft–Gault (CG) formula. Because plasma creatinine level is highly correlated with muscle mass, we hypothesized that an abnormal body composition with a low lean body mass (LBM) percentage [(LBM/weight) × 100] may result in(More)
