NCT03863197

Brief Summary

A randomized controlled trail will be carried out to investigate the effect of a 12-week supervised home-based progressive strength intervention in children with spastic cerebral palsy aged 5-11 years. The results of this strength intervention aiming for increased strength and muscle hypertrophy will serve as input for a clinical decision making framework based on muscle and tendon architecture.

Outcome Measures

Primary Outcomes (6)

  • Change in Muscle Size Parameter

    Estimation of muscle volume by 3D freehand ultrasonography.

    baseline, post-intervention (12-weeks)

  • Change in Muscle Length

    Estimation of muscle length parameters by 3D freehand ultrasonography from origo to muscle tendon junction.

    baseline, post-intervention (12-weeks)

  • Change in Echogenicity Intensity

    Estimation of echogenicity intensity by 3D freehand ultrasonography on an 8-bit greyscale (256 values ranging from 0 to 255). Echogenicity intensity was defined over the whole muscle volume. Echogenicity intensity refers to the brightness of a muscle seen on the ultrasound image, which reflects how much sound is being bounced back (or "echoed") by the tissue. Higher echo-intensity (i.e., higher values) often indicates increased fat or fibrous tissue within the muscle and is therefore seen as a worse outcome. Whereas low echo-intensity (i.e., lower values) indicate less non-muscular tissue in the muscle, therefor higher quality and a better outcome.

    baseline, post-intervention (12-weeks)

  • Change in Isometric Muscle Strength

    Evaluation of isometric muscle strength by Instrumented Weakness Assessment.

    baseline, post-intervention (12-weeks)

  • Change in Functional Muscle Strength - Muscle Endurance

    Evaluation of functional muscle strength by 30-sec maximum repetition tests of the Adapted Functional Strength measure. For unilateral exercises (lateral step-up and unilateral heel raise) all affected legs were assessed.

    baseline, post-intervention (12-weeks)

  • Change in Functional Muscle Strength - Maximum Jumping Distance

    Evaluation of standing long jump by the Adapted Functional Strength measure.

    baseline, post-intervention (12-weeks)

Secondary Outcomes (2)

  • Change in Gross Motor Function

    baseline, post-intervention (12 weeks)

  • Change in Walking Capacity

    baseline, post-intervention (12 weeks)

Other Outcomes (3)

  • Change in Quality of Life

    baseline, post-intervention (12 weeks)

  • Change in Functionality

    baseline, post-intervention (12 weeks)

  • Change in Patient Reported Physical Function

    Baseline, post-intervention (12 weeks)

Study Arms (2)

Intervention group

EXPERIMENTAL

During a 12-week period children receive 3-4 sessions of progressive strength training per week on top of the usual care. All children will be provided with an individualized training program and supporting equipment. One or 2 session per week will be performed under supervision of the physical therapist, whilst the remaining sessions will be performed at home. Progression is closely monitored by the principal investigator and training programs are adjusted if necessary.

Behavioral: Progressive strength training

Waitlist-control group

NO INTERVENTION

The waitlist-control group will continue their usual care without additional treatment for 12-weeks, followed by a 12-week period of progressive supervised home-based strength training.
