      Three dimensional gait analysis is widely accepted as a general measure of functional ability&#xD;
      among individuals as it is related to health, well-being and quality of life. To diagnose&#xD;
      subtle changes/deviations in gait and to correctly interpret gait, a reference gait database&#xD;
      of healthy subjects is required. Computer Assisted Rehabilitation Environment (Caren) is a&#xD;
      new gait analysis system which combines the 3D motion captures system with a split belt force&#xD;
      plate instrumented treadmill and a virtual reality environment. This system enables to&#xD;
      analyses several successive steps, which is impossible in the standard overground&#xD;

    <textblock>
      Gait is one of the most important activity of daily life for humans. In clinical and research&#xD;
      settings, gait performance is widely accepted as a general measure of functional ability&#xD;
      among individuals. Computer Assisted Rehabilitation ENvironment (CAREN; Motek Medical,&#xD;
      Amsterdam, The Netherlands) is a relatively novel system to analyze gait in a safe and&#xD;
      accurate way. CAREN consists of an instrumented split-belt treadmill mounted onto a&#xD;
      6-degree-of-freedom motion platform in combination with a Virtual Environment projected on a&#xD;
      180° semi-cylindrical screen. Two force plates underneath each belt and 12 3D motion capture&#xD;
      cameras (VICON system) allow an accurate analysis of gait which is expressed by kinematic,&#xD;
      kinetic, spatiotemporal en dynamic balance parameters. Currently at the MUMC+, CAREN-based&#xD;
      gait analysis is used for clinical purposes and is increasingly more applied to contribute in&#xD;
      clinical diagnostics and decision-making and to evaluate interventions and rehabilitation&#xD;
      programs. Besides, the CAREN system is applied in gait analysis laboratory settings as an&#xD;
      alternative or an additive to over ground gait analysis. However, due to its novelty, size,&#xD;
      high costs, and complexity, the CAREN system is not a widely accessible technology.&#xD;
      Literature is limited and research is still in progress. From these experiences, it is known&#xD;
      that CAREN is safe in use.&#xD;
&#xD;
      An individuals' walking pattern is variable and can change due to several factors such as&#xD;
      advancing age. Furthermore gait is influenced by body characteristics such sex, body height&#xD;
      and mass. Gait also changes as a result of health-related factors such as pain and diseases.&#xD;
      Moreover gait can change through rehabilitation and training. This all suggests that human&#xD;
      gait analysis is useful for clinical purposes, for example for diagnostics or to evaluate&#xD;
      rehabilitation programs. However to apply human gait analysis in clinical practice, it is&#xD;
      crucial to have insight into the normal walking pattern of individuals. A gait database of&#xD;
      healthy subjects with varying subject characteristics (e.g. age) is required to ensures that&#xD;
      gait is correctly interpreted. This database will give further insight in the dynamics of&#xD;
      walking, clarifying the level and proportion in which gait is affected by subject&#xD;
      characteristics and walking speed. This insight will improve the interpretation of gait, and&#xD;
      thus contribute to improved clinical diagnostics and follow up capabilities. In addition the&#xD;
      database will be relevant in clinical practice as it quickly puts into perspective gait of&#xD;
      patients. Moreover it enables the detection of subtle changes in gait (e.g. after&#xD;
      intervention).&#xD;
&#xD;
      Objective and hypothesis:&#xD;
&#xD;
      This research is a single center descriptive study to create a reference database of gait of&#xD;
      healthy adults of different ages. Six age groups are composed (18-29yrs, 30-39yrs, 40-49yrs,&#xD;
      50-59yrs, 60-69yrs, &gt;70yrs), existing of 20 males and 20 females.&#xD;
&#xD;
      This descriptive study aims to build a reference gait database for healthy subjects based on&#xD;
      CAREN including kinematic, kinetic, spatio-temporal and balance parameters. Values for gait&#xD;
      parameters of healthy adults will be created for varying age groups and sex. In addition,&#xD;
      knowing the impact of walking speed on various gait parameters, gait parameters of healthy&#xD;
      subjects will be clustered per walking speed, taking sex and age into account.&#xD;
&#xD;
      Primary Objective:&#xD;
&#xD;
      A descriptive study to collect a Caren-based reference database for healthy gait.&#xD;
&#xD;
      Secondary Objectives:&#xD;
&#xD;
        -  To investigate effects of subject characteristics such as age, sex and leg length on&#xD;
           gait kinematic, kinetic, temporal-spatial and balance parameters.&#xD;
&#xD;
        -  To investigate the relation between walking speed and gait kinematic, kinetic,&#xD;
           temporal-spatial and balance parameters.&#xD;
&#xD;
      Methods:&#xD;
&#xD;
      This is a single center descriptive study performed at the department Physiotherapy of the&#xD;
      Maastricht University Medical Center (MUMC+) in which gait of healthy adult volunteers of&#xD;
      varying ages is obtained by the new Computer Assisted Rehabilitation ENvironment (Caren)&#xD;
      system. The collected data will be used to create a database for gait parameters of healthy&#xD;
      subjects.&#xD;
&#xD;
      120 healthy men and 120 healthy women, equally divided over the six age groups (18-29j,&#xD;
      30-39j, 40-49j, 50-59j, 60-69j, &gt;70j) are included.&#xD;
&#xD;
      The healthy adult volunteers will walk at different walking speeds at the Caren system.&#xD;
&#xD;
      First, the comfortable walking speed of the subject is determined using a ramp protocol. This&#xD;
      includes that subject starts walking at 0.5m/s and that the speed is increased every second&#xD;
      by 0.01m/s until the subject reached the comfortable walking speed. This is repeated 3 times.&#xD;
      The average of these 3 walking speeds is used as comfortable walking speed. Afterward, the&#xD;
      subject walks for 5 minutes at the fixed comfortable speed to get familiarized to the system.&#xD;
      After familiarization, the measurement starts. The volunteers will walk at comfortable speed,&#xD;
      at a slow speed (comfortable speed - 30%), a fast speed (comfortable speed + 30%) and at a&#xD;
      slower speed (fixed at 0.5km/h). These four conditions are randomly applied to eliminate a&#xD;
      possible effect of sequence of performed walking speed (and thus familiarization) on gait.&#xD;
      Every measurement is proceeded by a 2 minute habituation period at that specific walking&#xD;
      speed. Subjects will wear a safety harness to avoid falling. In addition adults wear standard&#xD;
      shoes (gymnastic booties) provided by the lab to avoid shoes effects.&#xD;
&#xD;
      Gait kinematics (joint angles), kinetics (joint moments and power), spatio-temporal&#xD;
      parameters (e.g. stride length) and dynamic balance parameters (e.g. margins of stability)&#xD;
      will be determined. Values for gait parameters of healthy adults will be created and&#xD;
      clustered for varying age groups, sex and walking speeds.&#xD;

        The aim of the study is to create a reference database consisting of 240 healthy (120 men,&#xD;
        120 women), ranging from 18 years to &gt; 70yrs. For each of the six age categories (18-29yrs,&#xD;
        30-39yrs, 40-49yrs, 50-59yrs, 60-69yrs, &gt;70yrs), 20 men and 20 women will be included.&#xD;
        Assuming that 10% of the volunteers (especially elderly) may drop out because subjects&#xD;
        cannot complete the protocol due to fatigue, impaired condition, fear etc., an additional&#xD;
        10% will be recruited to ensure that 240 subjects will be included at the end. This results&#xD;
        in a total of 264 subjects that will be recruited. When subjects do not want to continue&#xD;
        participating in the study and want to stop the procedure, the subjects can stop at any&#xD;

      slower speed (fixed at 0.5km/h). These four conditions are randomly applied to eliminate a
      possible effect of sequence of performed walking speed (and thus familiarization) on gait.
      Every measurement is proceeded by a 2 minute habituation period at that specific walking
      speed. Subjects will wear a safety harness to avoid falling. In addition adults wear standard
      shoes (gymnastic booties) provided by the lab to avoid shoes effects.

      Gait kinematics (joint angles), kinetics (joint moments and power), spatio-temporal
      parameters (e.g. stride length) and dynamic balance parameters (e.g. margins of stability)
      will be determined. Values for gait parameters of healthy adults will be created and
      clustered for varying age groups, sex and walking speeds.
