Description of intervention(s) / exposure

Clinical trial parallel in patients with cerebral palsy. Two-arm, parallel-groups and randomised. Intervention exposure exercise program version "face to face" (control group) or "remote" (exposure group) both with Nintendo Wii balance board.
A virtual reality-based exercise protocol using Wii therapy (W-t) with Nintendo Wii balance board an “exposure-arm” performed by the parents or caregivers from patients' homes, and physiotherapists from the rehabilitation center and from the Special School each one will be guided remotely from the telerehabilitation center of the University of Talca. A total of 18 sessions W-t will be deliver over a period of 6 weeks with a frequency of 3 times per week (Monday, Wednesday and Friday) for 25 minutes each session and four weeks of follow-up in participant’s children and adolescent with spastic hemiplegic cerebral palsy. Each participants will execute three series of exercise with manual guidance and verbal instructions for the first 2 weeks and only verbal instructions by a parents or caregivers or physiotherapists in the following weeks. The first two series included Snowboard, Penguin Slide, and Super Hula Hoop; the third series was deep breathing in the Yoga game. The participants will be standing with their arms and hands at their sides, in a relaxed manner, during the first series. Each game will be repeat in a standing position and with their hands on their waist during second series. Finally, the participants will be instruct to maintain their posture and be as relaxed as possible with eyes open (EO) and later eyes closed (EC) during the third series. W-t will consist of a virtual reality training session using the Nintendo Wii balance board console for 25 min each session. This programme is based on previous studies, that demonstrate the training of balance is in all three planes of motion. For monitor adherence to the intervention will be through telephone reminders and direct observation by study personnel.

Comparator / control treatment

Comparator treatment will is face to face version:
A virtual reality-based exercise protocol using Wii therapy (W-t) with Nintendo Wii balance board this arm (face to face version, F/F) will perform only a physiotherapist towards the patient during six weeks of training and four weeks of follow-up in participant’s children and adolescent with spastic hemiplegic cerebral palsy. The exercise protocol is the same as for the exposure group, the difference is that the patient is face to face with the physiotherapist.

Outcomes

Primary outcome [1]

Postural balance through CoP sway area (CoPSway), which is defined as the total trajectory that the CoP makes in the medial-lateral (ML) and anterior–posterior (AP) directions. Posturography (force plate) has been widely used to quantify balance, and is considered the gold standard within the laboratory equipment, as it is able to measure the amount of sway by using the center-of-pressure (CoP) displacements.
CoPSway have shown that this is a reliable and valid measure of balance during standing in different clinical and nonclinical populations. Greater values of CoP sway (i.e. sway area) indicate poorer balance control when standing still.
Participants stood on a force plate with their feet at shoulder–width distance and in a comfortable position. Posturography will be assess under six conditions for 30 seconds each: (i) eyes open (EO), (ii) eyes closed (EC), (iii) mediolateral displacement of body guided by auditory stimuli (sound) at a frequency of 30Hz and (iv) then 60Hz, both with EO and (v) mediolateral and (vi) anteroposterior displacement of body with virtual environment. Postural balance evaluation will be complete within 20 min.

Data were collected and recorded at 200 Hz using an AMTI OR6-7 forceplate and AMTI-NetForce software (AMTI Inc., Boston, MA, USA). A procedure written in Matlab R2012 (Mathworks Inc., Natick, MA, USA) was used for low-pass filtering data (second-order Butterworth, 40 Hz cut-off frequency).

Timepoint [1]

Baseline, at 2, 4 and 6 weeks (primary timepoint) during the intervention (a Friday or the last day of these weeks), and 8 and 10 weeks (follow up) a Friday or in the last day of these weeks, respectively.

Secondary outcome [1]

Standard desviation of CoP in the mediolateral (SDML) and the anterior-posterior (SDAP) directions, are a composite secondary outcome. Standard deviation measures (SDML and SDAP), both reflect the variability of the CoP displacements, hence, of the motor responses aimed to minimize postural sway.

Secondary outcome [2]

Velocity of CoP in in the mediolateral (VML) and the anterior-posterior (VAP) directions, are a composite secondary outcome. Greater values for CoPSway indicates poorer balance control as CoP gets closer to the limit of stability, which demands rapid stabilization responses expressed in greater CoP velocities (VML and VAP).

Efficacy

Statistical methods / analysis

The sample size was calculated in order to detect clinically relevant changues in the effects postural balance of W-t face to face versus remote version at six weeks. Based on data from earlier studies (V.F Gatica et al., 2014; Gatica-Rojas V, et al., 2017; Gatica-Rojas V, et al., 2017), We considered a standard deviation of 4.974 cm2, a significance alpha level of 0.05, 80% statistical power, and with an allowance for 5% attrition, we required a minimum of 20 participants in each group (total sample of 40).

Summary

Brief summary

This research project seeks to implement an exercise program with virtual environments generated through the Nintendo Wii console and the balance board (Wii therapy, W-t) via telerehabilitation to improvement the postural balance in children and adolescents with cerebral palsy of type spastic hemiplegia. A clinical trial design whose objective will be to compare the effectiveness in improvement postural balance of face-to-face Wii therapy (physiotherapist with the patient) versus remote (parents / caregivers). Wii therapy face to face versus remote version are equivalent in their effects for the postural balance.
