Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The application of functional electrical stimulation on children aged 5 to 18 years with cerebral palsy - spastic hemiplegia (Winters Gage and Hicks classification Type 1 and 2). Children will be required to wear a small portable device on their leg which will stimulate the ankle dorsiflexors during the swing phase of gait for a period of 6 weeks. Children will be expected to wear the device for at least 1 hour per day, 6 days a week throughout this 6 week intervention phase.

There are 3 phases to this study as this is an ABA single subject design. The first phase is the preintervention phase which is 6 weeks in duration. During this phase, participants will be asked to continue with their usual regime. The next phase is the B- intervention phase which as described earlier is also 6 weeks. The final phase is the A - post intervention phase which will last up to 12 weeks. This phase will determine if there are any carry over effects from the intervention and if there are, how long they will last for. Assessments will occur weekly throughout the 3 phases with 2D gait video taken every 3 weeks.

Outcomes
Primary outcome [1] 266794 0
Selective Motor Control - Measurement of selective and isolated dorsiflexion on a 5 point scale (Boyd and Graham 1999)
Timepoint [1] 266794 0
Weekly throughout the 3 phases of the study
Primary outcome [2] 266795 0
Isometric Muscle Strength using a Hand Held Dynamometer for dorsiflexion and plantarflexion of the ankle joint
Timepoint [2] 266795 0
Weekly throughout the 3 phases of study
Primary outcome [3] 266796 0
2D gait video analysis will be used to determine peak dorsiflexion during swing as well as degree of dorsiflexion at initial contact with and without the electrical stimulation. Physician Rating Scale for Gait Analysis (using Boyd et al 1999) will be used.
Timepoint [3] 266796 0
2D gait video will occur before the commencement of the first phase of the study (6 weeks pre intervention phase to establish baseline) and every 3 weeks there after until the subject is 12 weeks post intervention.
Secondary outcome [1] 276399 0
Range of Motion will be measured using manual goniometry for the popliteal angles (bilaterally) as well as dorsiflexion with knee flexion and extension and ankle eversion in plantigrade position.
Timepoint [1] 276399 0
Weekly thorughout the 3 phases of the study
Secondary outcome [2] 276400 0
Spasticity using the Modified Tardieu and Australian Spasticity Assessment Scale for hamstrings, gastrocnemius, soleus and tibialis posterior
Timepoint [2] 276400 0
Weekly throughout the 3 phases of the study
Secondary outcome [3] 276401 0
Single Limb Balance will be measured by the length of time (using a stop watch) the subject can balance on one leg for
Timepoint [3] 276401 0
Weekly throughout the 3 phases of the study
Secondary outcome [4] 276402 0
Calf Circumference - circumferential measurements will be taken of the leg
Timepoint [4] 276402 0
Weekly throughout the 3 phases of the study
Secondary outcome [5] 276405 0
Subjective Reports from the Subjects using a questionnaire which focuses on how the subjects perceive the intervention and the effects it has on their mobility
Timepoint [5] 276405 0
Pre 6 week intervention, Post intervention and then again at 6 weeks and 12 weeks post intervention.
