Normative Database for Gait Analysis on the GRAIL UZ Gent

The aim of this study is to collect a large set of norm/control data on an instrumented treadmill (the Gait Real-time Analysis Interactive Lab - GRAIL) at the university hospital of Ghent for the purpose of clinical studies as well as for clinical interpretation.

We hypothesize that this norm/control data will provide reference data of the normal gait patterns in the healthy population such that we can then use it to identify gait abnormalities in populations with pathology.

The following data will be collected on the GRAIL while subjects walk at different gait speeds: 3D kinematics, kinetics, and EMG.

Additionally, 3D kinematics, kinetics, and EMG data will be collected when performing either a cognitive (Stroop Color and Word Test) or motor (requiring arm swing) dual-task while walking at comfortable walking speed.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy participants

Treatment and study plan

Walking on an instrumented treadmill

Other

Participants will be asked to walk at different gait velocities for 1 minute. The treadmill speed will be increased incrementally at 0.1m/s intervals until just before running.

Walking on an instrumented treadmill while dual-tasking

Other

Participants aged between 6 and 17 years will be asked to walk at comfortable walking speed while playing either a cognitive (Stroop Color and Word Test) or motor (requiring arm swing) game.

Primary outcomes

  1. Kinematics

    Time frame: single point assessment in 1 day

    3D kinematics of lower and upper limb joints while walking (degrees)

  2. Kinetics

    Time frame: single point assessment in 1 day

    3D kinetics of lower limb joints while walking (Nm)

  3. EMG

    Time frame: single point assessment in 1 day

    Muscle activity of 32 lower and upper limb muscles (micorvolts)

  4. EMG synergies

    Time frame: single point assessment in 1 day

    Synergy analysis will be carried using the EMG data (variance accounted for -VAF)

  5. Spatiotemporal parameters

    Time frame: single point assessment in 1 day

    Spatial parameters (m)

  6. Spatiotemporal parameters

    Time frame: single point assessment in 1 day

    Temporal parameters (s)

  7. Spatiotemporal parameters

    Time frame: single point assessment in 1 day

    Walking velocity (m/s)

Secondary outcomes

  1. Gait deviation index

    Time frame: single point assessment in 1 day

    Based on kinematics, the lower-limb gait deviations will be calculated (degrees)

  2. Game result (cognitive task)

    Time frame: single point assessment in 1 day

    Score (% correct)

  3. Game result (motor task)

    Time frame: single point assessment in 1 day

    Score (% correct)

    Standardized tool to indentify motor functioning in children

  6. Developmental Coordination Disorder Questionnaire (DCDQ)

    Time frame: single point assessment in 1 day

    Brief parent questionnaire to screen for coordination disorders in children
