About

There is increasing evidence that physical activity during childhood and adolescence has an important impact on health and behavior outcomes. Lack of physical activity is currently a major concern for the total population and especially for children and adolescents. People with disabilities are at risk for the same health problems as the general population. Due to their disabilities, they have a higher risk for developing secondary conditions that may further affect their health and quality of life.The goals of this project are to develop and evaluate new approaches of treatment for children with cerebral palsy (CP) and to develop low cost tests for evaluating motor functions in natural environments.

The overall aim is to raise awareness of, and promote, a physically active lifestyle for Middle East teenagers with disabilities due to CP by means of a collaborative Jordanian-Israeli-Palestinian-Moroccan applied research project. Specific objectives include:

1. Evaluation of baseline levels of physical activity in large populations of children and teenagers with CP in the communities of the participating countries by long-term monitoring by accelerometers.
2. Conducting a randomized clinical trial to compare the efficacy of an "experimental" physical training program with a treadmill training program in two groups. The experimental training program is based on results of recent motor control studies, as well as the "motor learning" approach to facilitate transfer and retention of learned walking activities.
3. Disability Advocacy through dissemination of activity focus programs, raising awareness, making use of new technologies and enhancing and developing the skills and training of personnel working with populations with CP.
4. Continuing the expansion of collaborative research efforts pertaining to children and teenagers with physical disabilities between Arab countries and Israel through sharing of skills and knowledge by exchange visits, meetings and seminars and joint training, pediatric physiotherapists and physical educators.

Full description

Stage I: Design A cross sectional research design.

Study participants for stage I: A total of 400 teenagers with CP will be monitored in this stage. All partners of this project will obtain approval for experiments on human subjects from their local committees. Each subject (or parents/guardians for the participation of minor subjects) will be able to sign an informed voluntary consent form, consistent with the Helsinki Declaration, after reading a detailed explanation and having an oral Q/A session with the investigator.

Recruitment: Prospective focused direct mailing or personal contacts will be initiated with the parents/guardians of children with CP who are ambulatory. Subsequent screening will be done by phone interview.

Participants at each center/country. 100 teenagers with CP, age 14-20 yr (50 age 14-17 yr and 50 age 18-20 yr). GMFCS levels II; III and IV.

Measurements:

Stage I:

The ActivePal accelerometer is a research instrument for long-term assessment of ambulatory activity during day-to-day life. Baseline functional status will be measured before interventions, including a completion of a socio-economical questionnaire.

Stage II: Randomized control trial of three training programs to improve the physical activity level and comparison between low and high costs interventions.

Study participants for Stage II. Thirty teenagers with CP at each center (total number of 120 at the four centers) will be matched according to age and GMFCS level (II and III) and randomly assign to one of three treatment programs. Subjects will be recruited from those in the first stage of the project. All partners of this project will obtain approval from their local committees. Each subject (or parents/guardians for the participation of a minor subject) will sign an informed voluntary consent form, consistent with the Helsinki Declaration, after reading a detailed explanation letter and having an oral Q/A session with the investigator.

Measurements:

2-Treadmill training measures will include total training time, step length, and with the split treadmill the velocity gap will also be recorded during each session 3-The gross motor function measure (GMFM) with dimensions D and E (standing, walking, running, jumping) will be used 4-Mechanical efficiency will be measured by the stair-climbing test.

Statistical analysis:

Repeated measures analysis of variance (ANOVA) will be used to determine the effects and compare the three treatment methods. The repeated measures factor will be the pre-post measurements and the grouping factors will be the functional levels (GMFCS) and treatment methods. Differences between pre-post measurements among the three methods will also be tested by one-way ANOVA. A p-value of < 0.05 will be considered significant.

Enrollment: 120 estimated patients

Sex: All

Ages: 14 to 20 years old
