Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: All participants: - Functional Ambulation Categories 3-5 - Age 18 years and older - Ability to stand independently (on bare feet) for at least 30 minutes Stroke patients: - Unilateral Supratentorial Stroke longer than 6 months ago Parkinson patients: - Idiopathic Parkinson's Disease - Hoehn & Yahr Stages 1-3

Design outcomes

Primary

Measure	Time frame
The stepping threshold, defined as the highest perturbation intensity (in m/s2) at which balance is maintained with a feet in place response.	—

Secondary

Measure	Time frame
- Kinematic variables such as joint angles and Centre of Mass (CoM) - Margin of Stability defined as the minimum distance between the vertical projection of the CoM and the border of the Base of Support (BoS) during perturbations at the stepping threshold. - EMG (electromyographic) variables such as onset latency and amplitude.	—
