Study summary

The purpose of this multicentric study is to assess the impact of C-BRACE on mobility, endurance, confidence, participation, satisfaction, psychosocial adjustment and quality of life in community ambulators using a Stance Control Orthosis.

Read the detailed description

During two months of inclusion period, the investigators invite all patients matching with inclusion criteria for an enrolment visit, collect written consent and record general patient information. The eCRF (electronic Case Report Form) assigns the enrolled patient into one group for the trial (C-BRACE/SCO or SCO/C-BRACE), in a randomized order. The assessments are performed after 2 month follow-up period with each orthosis with a minimal wash-out period of 2 weeks.

Study arms

  • Experimental
    C-BRACE/SCO

    The patient is first fitted during 2 months with the C-BRACE orthosis, them, after 2 weeks wash-out period, the patient is fitted with its Stance Controlled Orthosis (SCO).

    Device: C-BRACE · Device: SCO

  • Other
    SCO/C-BRACE

    The patient is using its Stance controlled orthosis (SCO) during 2 months, then, after 2 weeks wash-out period, the patient is fitted with the C-BRACE orthosis.

    Device: C-BRACE · Device: SCO

Interventions

  • DeviceC-BRACE

    The C-BRACE is a custom made Knee-Ankle-Foot-Orthosis with a microprocessor-controlled hydraulic knee-joint articulation. The C-BRACE technology offers to a patient with knee locking deficiencies the following advantages: approximation of the physiological gait pattern, stability while standing and walking, adaptation to various surfaces, inclines, gait situations and walking speeds.

  • DeviceSCO

    The SCO is a custom made Knee-Ankle-Foot-Orthosis with a knee-joint locked during stance phase and released during swing phase.

What researchers measure

Primary outcomes

  1. PLUS-M™ - Mobility

    12-items Self-reported measure of mobility as the ability to move intentionally and independently from one place to another.

    Time frame: 2-months

Secondary outcomes

  1. 6 minutes walk test

    Distance walked in 6 minutes

    Time frame: 2-months

  2. ABC-s Activities-specific Balance Confidence - simplified

    15-items self-reported measure of the perceived balance confidence an individual has while completing various ambulatory activities on 4-levels scale.

    Time frame: 2-months

  3. PSFS - Patient Specific Functional Scale

    Patients will be asked to identify three activities that they are having difficulty or are unable to perform because of their condition. Patients will then be asked to rate their ability to perform each activity on a numerical scale ('0' being unable to perform the activity, and '10' being able to full perform the activity).

    Time frame: 2-months

  4. PIADS - Psychosocial Impact of Assistive Devices Scale

    26-items questionnaire that assess the effects of an assistive device on functional independence, well-being and quality of life from the person's disability's point of view. Each item is noted on a 7-points Likert scale going from -3 (maximum negative impact) to +3 (maximum positive impact).

    Time frame: 2-months

  5. EQ-5D-5L - Quality of Life

    Self-reported measure of health status composed of 5 dimensions: mobility, ability to self-care, ability to undertake usual activities, pain and discomfort, anxiety and depression. Each dimension is rated on a 5-point scale.

    Time frame: 2-months

  6. QUEST 2.0 - Satisfaction

    12-items self-reported measure on patient's satisfaction regarding the technology of the device and the services around the device. It allows the patient to express himself on the 3 most important criteria to him.

    Time frame: 2-months
