Effect of Vibration on Muscle Properties, Physical Activity and Balance in Children with Cerebral Palsy

January 6, 2025 updated by: Christopher Modlesky, University of Georgia
The aim of the 6-month randomized controlled trial, with 6-month no treatment follow-up, is to examine the effects of low-magnitude vibration on muscle, physical activity, and balance in children with spastic cerebral palsy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Cerebral palsy (CP) is a movement disorder that affects over 800,000 people in the U.S. Due to the limited mobility associated with the disorder, individuals with CP have an increased risk of chronic diseases, such as cardiovascular disease, diabetes mellitus and osteoporosis, compared to the general population. Therefore, identifying treatment strategies is of utmost importance. The aim of this study is to examine the acute and chronic effects of low-magnitude vibration on muscle, physical activity, and balance in children with CP. Fat concentration and muscle will be assessed using imaging techniques. Physical activity will be assessed using activity monitors. Balance will be assessed using clinical and biomechanical tests. Children with CP will be tested at five time points: baseline, 1 and 6 months after standing on a vibration platform daily 10 minutes per day, 1 and 6 months post treatment (7 months and 12 months from baseline, respectively). The findings from the proposed study will help us determine if vibration shows promise as a treatment for the impaired mobility, lower physical activity and higher risk of chronic disease in individuals with CP.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

5 years to 11 years (Child)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Vibration Platform
The vibration group will stand on a platform that emits a mild vibration 10 minutes per day for 6 months. There will also be a 6 month no-treatment period.
Device: Vibration Platform
The vibration platform will emit a mild vibration when the participant stands on it 10 minutes per day for 6 months.
Placebo Comparator: Placebo Platform
The placebo group will stand on a placebo platform 10 minutes per day for 6 months. There will also be a 6 month no-treatment period.
Device: Placebo Platform
The placebo platform will not vibrate when the participant stands on it 10 minutes per day for 6 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in fat concentration
Time Frame: Baseline, 6 months and 12 months
Change in fat concentration assessed using imaging techniques
Baseline, 6 months and 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
