  <brief_summary>
    <textblock>
      The ARCANGEL study evaluates the feasibility of introducing ARC (Assisted Rehabilitation&#xD;
      Care), a new device for home-based post-stroke rehabilitation in the current clinical&#xD;
      practise. All the stroke survivors included in the study will received their own equipment to&#xD;
      be used at home for 6 months.&#xD;
    </textblock>
  </brief_summary>
  <detailed_description>
    <textblock>
      Some relevant studies have indicated that approximately 36% of these survivors (i.e. more&#xD;
      than 9 million in 2013 only) are left with significant disabilities 5 years after their&#xD;
      stroke, and &gt;40% (i.e. more than 10 million) require assistance with activities of daily&#xD;
      living.&#xD;
&#xD;
      Despite evidence that participation in formal rehabilitative therapies lessens disability&#xD;
      after stroke, less than a third receive inpatient or outpatient therapies. Of those who do&#xD;
      access therapies, the frequency of use varies by geographic location and socioeconomic&#xD;
      status. In this context, the development of new strategies able to expand the access to&#xD;
      rehabilitation to an increased number of stroke patients, also enabling home-based conduction&#xD;
      and monitoring, are increasingly necessary both for patients, their families and for the&#xD;
      healthcare and social services sustainability. Since many barriers could limit access to&#xD;
      continuous physical rehabilitation for these patients, devices that complement or assist in&#xD;
      the rehabilitation process can be of great help.&#xD;
&#xD;
      Among different approaches proposed by the scientific community, technological systems based&#xD;
      on accelerometers seem to be among the most promising. Accelerometers are small low cost&#xD;
      electronic devices, able to measure body parts acceleration on three axes. Many researchers&#xD;
      have already highlighted that accelerometers have the capability to provide reliable and&#xD;
      objective information on quantity and intensity of patient limbs movements during recovery&#xD;
      process.&#xD;
&#xD;
      Wearable devices such as accelerometers allow to monitor exercises and daily activities.&#xD;
      Machine learning methodologies have already been applied for modelling and contextualizing&#xD;
      accelerometric signals to identify activity types (walking, dressing, eating, washing up,&#xD;
      etc.) or to recognize to which rehabilitative exercise these signals are linked to. These&#xD;
      techniques allow to estimate the recorded movement quality, providing information useful to&#xD;
      identify the context in which movements are performed. Results of these type of studies are&#xD;
      promising and they demonstrate that machine learning is a preferred approach for&#xD;
      accelerometric data analysis, since able to exceed actual limits that today are hampering&#xD;
      commercial product development for real time analysis of movement.&#xD;
&#xD;
      Within this scenario, Camlin-ARC takes its place. ARC is a platform based on wearable&#xD;
      inertial sensors and machine learning algorithms, designed to bring the rehabilitation at&#xD;
      post-stroke patients' home, following hospital discharge.&#xD;

    <measure>Euro Quality of Life - 5 Dimension (EQ-5D) Health Questionnaire summary index</measure>
    <time_frame>6-month evaluation</time_frame>
    <description>Euro Quality of Life - 5 Dimension (EQ-5D) is a standardised instrument that measures the health-related quality of life. It consists of a descriptive system and a Visual Analogue Scale (VAS). The descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension is divided into 3 levels (1 = no problem, 2 = some problems, 3 = to extreme problems). A unique health state is defined by combining 1 level from each of the 5 dimensions. Each state is represented by a 5 digit code (eg. 11111 = no problems on any of the 5 dimensions; 11223 = no problems with mobility and self care, some problems with usual activities, moderate pain or discomfort and extreme anxiety or depression). The EQ VAS records the patient's self-rated health (from 100 = best, to 0 = worst imaginable state). The EQ VAS is used to convert the EQ-5D states into a single index value, based on reference values available on EuroQoL Group website.</description>

      Care), a new device for home-based post-stroke rehabilitation in the current clinical
      practise. All the stroke survivors included in the study will received their own equipment to
      be used at home for 6 months.
Some relevant studies have indicated that approximately 36% of these survivors (i.e. more
      than 9 million in 2013 only) are left with significant disabilities 5 years after their
      stroke, and >40% (i.e. more than 10 million) require assistance with activities of daily
      living.

      Despite evidence that participation in formal rehabilitative therapies lessens disability
      after stroke, less than a third receive inpatient or outpatient therapies. Of those who do
      access therapies, the frequency of use varies by geographic location and socioeconomic
      status. In this context, the development of new strategies able to expand the access to
      rehabilitation to an increased number of stroke patients, also enabling home-based conduction
      and monitoring, are increasingly necessary both for patients, their families and for the
      healthcare and social services sustainability. Since many barriers could limit access to
      continuous physical rehabilitation for these patients, devices that complement or assist in
      the rehabilitation process can be of great help.

      Among different approaches proposed by the scientific community, technological systems based
      on accelerometers seem to be among the most promising. Accelerometers are small low cost
      electronic devices, able to measure body parts acceleration on three axes. Many researchers
      have already highlighted that accelerometers have the capability to provide reliable and
      objective information on quantity and intensity of patient limbs movements during recovery
      process.

      Wearable devices such as accelerometers allow to monitor exercises and daily activities.
      Machine learning methodologies have already been applied for modelling and contextualizing
      accelerometric signals to identify activity types (walking, dressing, eating, washing up,
      etc.) or to recognize to which rehabilitative exercise these signals are linked to. These
      techniques allow to estimate the recorded movement quality, providing information useful to
      identify the context in which movements are performed. Results of these type of studies are
      promising and they demonstrate that machine learning is a preferred approach for
      accelerometric data analysis, since able to exceed actual limits that today are hampering
      commercial product development for real time analysis of movement.

      Within this scenario, Camlin-ARC takes its place. ARC is a platform based on wearable
      inertial sensors and machine learning algorithms, designed to bring the rehabilitation at
      post-stroke patients' home, following hospital discharge.

measure: Euro Quality of Life - 5 Dimension (EQ-5D) Health Questionnaire summary index
time frame: 6-month evaluation
description: Euro Quality of Life - 5 Dimension (EQ-5D) is a standardised instrument that measures the health-related quality of life. It consists of a descriptive system and a Visual Analogue Scale (VAS). The descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension is divided into 3 levels (1 = no problem, 2 = some problems, 3 = to extreme problems). A unique health state is defined by combining 1 level from each of the 5 dimensions. Each state is represented by a 5 digit code (eg. 11111 = no problems on any of the 5 dimensions; 11223 = no problems with mobility and self care, some problems with usual activities, moderate pain or discomfort and extreme anxiety or depression). The EQ VAS records the patient's self-rated health (from 100 = best, to 0 = worst imaginable state). The EQ VAS is used to convert the EQ-5D states into a single index value, based on reference values available on EuroQoL Group website.
