Monitoring and Supporting Functional Skills among Children with Cerebral Palsy Ruth E. Benedict, DrPH, OTR Associate Professor Occupational Therapy Program Department of Kinesiology Objectives • To provide an overview of the strengths and limitations of classification systems and assessment tools for determining function among persons with CP • To present current estimates of the prevalence of gross motor function abilities among children with CP • To examine evidence for interventions intended to maximize function and support caregiving OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON Function & Participation Why care about function? • As therapists, that is what we do • Social vs. Medical model – International Classification of Functioning, Disability & Health (ICF) – Role of Environment • Predict future supports & service needs • Program planning & policy OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON Functional Limitations • Are associated with: – Greater need for services • Home health, Equipment, Therapy, Special Ed – Greater impact on family – Decreased access to health care services – Inadequate insurance – Perceived poorer quality interactions with providers OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON Functional Classification Gross Motor Function Classification System (GMFCS) – Palisano, R., Rosenbaum, P., Walter, S., Russell, D., Wood, E., Galuppi, B.

OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON 5 Levels of GMFCS LEVEL I - Walks without Limitations LEVEL II - Walks with Limitations LEVEL III - Walks Using a Hand-Held Mobility Device LEVEL IV - Self-Mobility with Limitations; May Use Powered Mobility LEVEL V - Transported in Manual Wheelchair OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON What does the GMFCS tell us? • Prediction of future motor ability – Reliable after 2 years of age • Answer or clarify common questions: – “Will my child ever walk?” • Guide treatment approaches and goals • Client/Caregiver education regarding long term equipment and care needs OCCUPATIONAL THERAPY PROGRAM, UNIVERSITY OF WISCONSIN-MADISON Stability & Decline of Function Hanna, S.E., Rosenbaum, P.L., Bartlett, D.J., Palisano, R.J., Walter, S.D., Avery, L., Russell, D.J.

MACS Level I: Handles objects easily and successfully. Do not restrict independence in daily activities. Level II: Handles most objects but with somewhat reduced quality and/or speed of achievement; alternative ways of performance might be used. Level III: Handles objects with difficulty; needs help to prepare and/ or modify activities. Activities are performed independently of they have been set up or adapted. Level IV: Handles a limited selection of easily managed objects in adapted situations. Requires continuous support and assistance and/or adapted equipment. Level V: Does not handle objects. Requires total assistance.

(2005) Methods Participants: Primary caregivers (N=19) of children and young adults with cerebral palsy (ages 3-22 years) receiving an Intrathecal Baclofen Pump who were recruited through a Spasticity & Movement Disorders clinic. Procedures: Caregivers completed 3 successive tasks: 1) transfer wheelchair to mat 2) dressing 3) transfer from mat to wheelchair Mean (Standard Deviation) Caregivers N = 19 Relation Mother Father Age < 45 years >= 45 years Weight (Kilograms) Height (Centimeters) Percent (at baseline) 89% 11% 0 months (N=19) 6 months (N=14) 12 months (N=8) ------- ------- -------- 41.9 (7.0) 42.6 (7.8) 44.7 (7.6) 53% 47% ---------- 80.0 (22.4) 85.9 (28.0) 86.0 (25.0) ---------- 165.1 (9.1) 167.6 (8.9) 167.6 (7.6) BMI < 30 >= 30 HR (bpm) 58% 42% ---------- VO2 (mL/kg/min) ---------- 29.1 (6.8) 30.2 (8.6) 30.6 (9.0) 73.5 (11.2) 73.5 (9.7) 74.4 (8.9) 11.7 (2.5) 11.4 (2.4) 12.3 (1.4) Correlations between subjective and objective measures of energy exertion Borg RPE (N=114) HR (N=116) Borg RPE HR .182 VO2 .488* .363* Controlling for Baseline HR & VO2 (N=110) Borg RPE HR .289 * VO2 .425** a Borg Ratings of Perceived Exertion Scale; b Heart rate; c Volume of oxygen consumed * p < 0.01; ** p<0.001 .630** VO2 Discussion • Borg appears to be sensitive to between and within person differences in exertion • Short duration or anaerobic nature of the caregiving tasks may have prevented capture of change in HR • Further research is needed to examine other components of perceived exertion (e.g. mental fatigue) • Some self-identified goals for ITB intervention show general improvement in performance and satisfaction • Limitations of the pilot nature of this work Acknowledgments WisADDS (Wisconsin Autism and Developmental Disabilities Surveillance) – – – – – Maureen Durkin, Principal Investigator Carrie Arneson, Project Coordinator Matt Maenner, PhD (doctoral student) Jean Patz, OTR, Clinician Reviewer Abstractors Waisman/UW Health SMD Team – – – – – – – – – Leland Albright Marcella Andrews Taryn Bragg Michael Braun Anne Harris Emily Kline Andrea Olson Rae Sprague Christa Tober CDC – ADDM Project – – – Marshalyn Yeargin-Allsopp Nancy Doernberg Kim Van Naarden Braun Alabama Site – – – – Russ Kirby Beverly Mulvihill Martha Wingate Sheree Chapman York Missouri Site – – – – Rob Fitzgerald Kathy Herndon Shulamit Portnoy Cathy Yungbluth And, of course, the many families and children whose lives are affected by cerebral palsy
