- Gait metrics collected using ActiGraph devices [ Time Frame: Maximum of 3 hours undertaking a semi-structured movement protocol ]To compare gait quality metrics collected using ActiGraph devices, APDM devices and GAITRite® walkway, during in-lab sessions. Accuracy of the sensor-derived metrics will be determined by computing the mean absolute percent error between the sensor-derived and reference standard metrics and assess the bias using Bland Altman plots and 95% limits of agreement. The agreement between sensor derived and reference standard metrics will be assessed using ICC and its 95% lower and upper confidence limits.
- Wear compliance of ActiGraph devices at home [ Time Frame: Up to 18 days ]Number of hours per day wearing the device and number of days with more than 10 hours of wearing for each participant will be recorded.
- Evaluate wearability of device in the lab setting and at home [ Time Frame: Up to 18 days ]
Participants or their parent/guardian will be asked to rate their assessment of how comfortable the devices were both at the end of the in lab session and after the at home monitoring period. The same questionnaire will be administered twice. The participant or the parent/guardian are requested to choose a statement on a five-point Likert Scale. The statements are:
Strongly disagree Disagree Neutral Agree Strongly agree
Participants or their parent/guardians will select the most appropriate statement which they felt reflected how comfortable they found the devices to put on, wear, and take off.
- To assess the ability of pediatric participants to perform a battery of lab-based tasks [ Time Frame: Maximum of 3 hours undertaking a semi-structured movement protocol ]Number of participants (overall and per age group) able to perform each of the 7 tasks and task-completion percentage (among total of 7 tasks) per participant.
- To evaluate the effect of floor surface on gait metrics [ Time Frame: Maximum of 3 hours undertaking a semi-structured movement protocol ]Gait metrics measured by devices across different floor surfaces.
- To assess the feasibility of recruiting pediatric participants to conduct a wearable device study [ Time Frame: 52 weeks ]Recruitment data listed by age group: number of participants contacted, screened and enrolled over time, time to enroll approximately 13 participants per group.
