Patient Perspectives and Quality of Life:Early PTClinResNet Outcomes James Gordon, EdD, PT, FAPTA Co-Principal Investigator, PTClinResNet Chair, Department of Biokinesiology & Physical Therapy, University of Southern California Combined Sections Meeting, San Diego, CA, February 2, 2006
What is PTClinResNet? • A clinical research network (CRN) to evaluate the efficacy of physical therapy interventions • Established by PT researchers at USC and elsewhere (Jan, 2003) • Funded by Foundation for PT ($1.5 million) and member institutions (almost $1 million) • Four separate randomized clinical trials (RCTs) • Subject recruitment and baseline data collection completed by end of 2005 • Common aim of all four RCTs • to determine whether exercise interventions can have a meaningful impact on patients’ quality of life
Purpose of this Symposium • To present baseline outcome measures in four clinical trials • To classify various outcome measures within ICF framework • To analyze relationships among outcome measures within and across ICF domains • To discuss relationships of these measures to subjective quality of life
Purpose of My Presentation • To provide a broad overview of PTClinResNet • To review ICF framework
Overview of PTClinResNet • Three aims: • Clinical research to evaluate efficacy of practice • Build the infrastructure to support clinical trials research • Education and training (knowledge transfer) • Overall Goal: • To identify and test strategies for improving function and reducing disability using exercise interventions designed to enhance muscle performance through dynamic task-oriented or muscle-oriented approaches
Four Randomized Controlled Trials • STEPS: Strength-training effectiveness post stroke • David Brown, Ph.D., P.T., Lead I • MUSSEL: Muscle specific strengthening effectiveness post lumbar microdiscectomy • Kornelia Kulig, Ph.D., P.T., Lead I • PEDALS: Pediatric endurance development and limb strengthening • Eileen Fowler, Ph.D., P.T., Lead I • STOMPS: Strengthening and optimal movements for painful shouldersin chronic spinal cord injury • Bryan Kemp, Ph.D., Lead I

Coordinating Center • Developed extensive manual of procedures • Standardization of assessments and treatment protocols • Available to other investigators • Centralized data management & statistical analysis • Data management center directed by Dr. Stan Azen • Facilitate communication among investigators and clinicians • Monthly conference call • Website • Executive committee, publications committee, etc.
Successful subject recruitment is a major accomplishment! • Estimated that 80% of all clinical trials fail to meet recruitment goals • (Marks et al, Statist. Med. 2001; 20:2683–2696) • Enhanced ability to recruit subjects for large clinical trials is a major advantage of clinical research networks
Baseline Data is Now Available for Analysis • Because some subjects are completing interventions and follow-up assessments, investigators remain blinded to group membership • Post-intervention data still not available in complete form • Therefore…today’s presentation will focus on baseline data • ICF Framework
ICF Classification System • International Classification of Functioning, Disability and Health • Refinement of earlier WHO and Nagi Models of Disablement • Overall Aim of ICF • to provide a unified and standard language and framework for the classification and description of health and health-related states
Contextual Factors ICF Model
Next… • How do we conceptualize outcome in terms of “Quality of Life”?
