Brief Summary:

Scoliosis is a progressive three-dimensional deformation of the spine during growth, with a prevalence of 80% in girls.

The treatments currently used are surgery and rigid brace, which aim to stabilize scoliosis evolution. The place of rehabilitation is disputed because the methods are multiple, non-standardized and the sessions are infrequent.

In a previous study (MOUVSCO, NTC02134704), researchers have identified systematic postural abnormalities in patients with scoliosis, and developped a virtual-brace (medical device, MD) to allow real-time self-correction of the trunk position.

The aim of the present study is to evaluate for the first time the efficacy of the virtual-brace on the correction of the posture of scoliotic patients.

The hypothesis is that intensified rehabilitation with the virtual-brace will improve pathological postures related to scoliosis.


Condition or disease Intervention/treatment Phase
Idiopathic Scoliosis Device: Night-time brace + virtual-brace Other: Night-time brace only Not Applicable

Detailed Description:

The present study is the first evaluation of the efficacy of the virtual-brace on scoliotic patients.

The efficacy of rehabilitation will be estimate on the correction of the posture of scoliosis patients over 6 months by comparing 2 groups: a control group of patients conventionally treated with a night-time brace (G0 group_conventional) and an experimental group of patients wearing a night-time brace, doing postural rehabilitation exercises with the virtual brace and follow-up visits with a physiotherapist (G1 group_virtual-brace).

Arm Intervention/treatment
Experimental: Night-time brace + virtual-brace
Patients are conventionally treated with night-time brace. Additionally, they use the new developped virtual-brace (MD).
Device: Night-time brace + virtual-brace

Patients will receive conventional treatment : wearing a night-time brace every night during 6 months.

Additionally :

  • They will perform 5 sessions of postural rehabilitation exercises per week (each of 30 minutes) with the virtual-brace (MD).
  • They will have also follow up consultations with a physiotherapist every 21 days, to evaluate treatment observance and to adapt postural exercises according to the results and difficulties encountered.

Conventional 3D motion capture Analysis (different trunk tasks and walk) will be performed to evaluate evolution of postural parameters at D0, D90 and D180.


Active Comparator: Night-time brace only
Patients are conventionally treated with night-time brace only.
Other: Night-time brace only

Patients will receive conventional treatment : wearing a night-time brace every night during 6 months.

Conventional 3D motion capture Analysis (different trunk tasks and walk) will be performed to evaluate evolution of postural parameters at D0, D90 and D180.





Primary Outcome Measures :
  1. Medio-lateral displacement during lateral inclination of scoliosis patients in the group with rehabilitation enriched by the virtual brace (group G1) compared with the reference treatment (group G0) at D180. [ Time Frame: 6 months ]
    Difference between D180 and D0 of the medio-lateral displacement of the pressure center during the lateral inclination in both groups G0 and G1. This parameter is evaluated during the conventional 3D motion capture analysis.


Secondary Outcome Measures :
  1. Quantification of kinematic, postural and electromyographic anomalies during trunk tilting and rotation (for both groups G0 and G1). [ Time Frame: 6 months ]
    Conventional 3D motion capture analysis with surface ElectroMyoGram (EMG) pattern's at D0, D90 and D180.

  2. Quantification of the quality of life evaluated with the Scoliosis Research Society Patient questionnaire (SRS-22), for both groups G0 and G1. [ Time Frame: 6 months ]
    Difference in the result of the SRS-22 questionnaire between D180 and D0. SRS-22 is a self-reported questionnaire assessing self-image, function, pain, mental health, and satisfaction with care with score range from 1 to 5 (1=worst and 5= best) for each 22 questions. The global score is the mean score of all questions.

  3. Quantification of kinematic feedback provided by the virtual-brace and their deviation from the prescription (only for group G1) [ Time Frame: 6 months ]
    Time course of the angular data of the trunk relative to the pelvis provided by the virtual brace, versus the prescribed exercises (evaluated every 3 weeks during the visit to the physiotherapist)

  4. Treatment compliance for the rigid-brace (for both group G1 and G0) [ Time Frame: 6 months ]
    Compliance with the wearing of the rigid brace reported in the patient follow-up logbook.

  5. Treatment compliance for the virtual-brace (only for group G1) [ Time Frame: 6 months ]
    Only for group G1 : effective rehabilitation time collected from the virtual brace's log files.

  6. Quantification of electroencephalogram (EEG) modifications during postural and walk initiation tasks (for both groups G0 and G1). [ Time Frame: 6 months ]
    Conventional 3D motion capture analysis with EEG records at D0, D90 and D180.

  7. Exploratory Objective : Descriptive analysis by group of all parameters related to postural disorders recorded during Conventional 3D motion capture analysis with EMG, EEG. [ Time Frame: 6 months ]
    Set of variables related to the severity of the postural disorder.
