Outcome Measures

Primary Outcome Measures

  1. Health-related quality of life measured by EQ-5D-5L [6 Months post implant]

    The EQ-5D-5L results shall be collected during study follow up visits

  2. Health-related quality of life measured by NHP (Nottingham Health Profile) [6 Months post implant]

    The NHP results shall be collected during study follow up visits
