Activity and Participation in Ambulatory Cerebral Palsy

Study Overview
=================
Brief Summary
-----------------
The investigators would like to understand how the physical activity levels and body size of a child with cerebral palsy (CP) in a clinical situations versus out in the community relates to what they want to do in day to day life (participation in life). The investigators believe that what a child really does out in day to day life will predict life participation to a greater degree than what they do in a structured clinical situation (i.e. therapy session with therapist). The investigators think that increased body size with normal growth is related to less physical activity and participation in day to day life for children with cerebral palsy (CP) who can walk. This project will use a novel accelerometer to measure walking activity during day to day life.

Detailed Description
-----------------
We want to know how the physical activity of children with walking problems or cerebral palsy (CP) relates to what they do in their day to day lives. We are looking for children who: Have walking problems that started before age 2 Have any type of cerebral palsy (CP) or primary problem that is a developmental movement disorder May have hemiplegia, diplegia, walking quadriplegia, May have ataxia, spastic, mixed tone, athetoid, or dyskinetic Ages 2 years to less than 10 years Able to do some functional walking with or without help(walkers, gait trainers) Project requires a one time visit to Seattle Children's Hospital of about 2 hours. Children and/or parents will complete surveys. The child will be tested for their gross motor and walking skills like at a physical therapy session. The child will be given an ankle monitor to wear for 7-10 days. They will return the monitor by mail with a questionnaire about what they did the last week. Families will receive a print out of their child's walking activity

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Children with cerebral palsy (CP)<br>ages 2 to < 10 years who are able to walk with or without an assistive device | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Community walking activity with the STEPWATCH accelerometer | Walking activity performance within the context of daily life will be measured with a monitor called the StepWatch. The StepWatch was specifically designed and validated for long-term assessment of ambulatory activity during day-to-day life. It is a small,waterproof, self-contained device that is worn on the ankle. It records the number of strides taken every minute for up to two months between downloads. | Assessed at one time point with a 7-10 walking sample | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Participation in day to day life activities | Participation will be quantified by two valid measures of pediatric life participation, the Children's Assessment of Participation and Enjoyment (CAPE) and the Assessment of Life Habits (Life-H for Children).The CAPE was designed to document the child's report of participation in day to day activities, while the Life-H for children is intended to describe a group of life habits that are characteristic of children in their environment (home, school and neighborhood). | Assessed as one time point by parental/child report of participation in the last 4 months |
