New 3D platform aims to steady the steps of Parkinson's and stroke patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients: adults aged 18 to 80 years. * Patients: confirmed diagnosis of one of the following chronic neurological conditions: stroke, Parkinson's disease, amyotrophic lateral sclerosis (ALS), or mild cognitive impairment (MCI). * Patients: able to understand and follow study procedures and provide informed consent. * Healthy volunteers: adults aged 18 to 65 years. * Healthy volunteers: able to understand and follow study procedures and provide informed consent. * Healthy volunteers: rehabilitation staff members from the participating centers. Exclusion Criteria: * Patients: severe psychiatric disorders or cognitive disorders that impair the ability to complete cognitive tests and self-report questionnaires. * Patients: unable to provide informed consent. * Patients: moderate to severe cognitive impairment, defined as an ECAS score below 81.92 in participants with ALS or a Raven's Matrices score below 18.36 in participants with mild cognitive impairment. * Patients: neurological or physical conditions that significantly limit lower-limb use and prevent standing on the platform, including lower-limb muscle strength of 3 or less on the Medical Research Council (MRC) scale. * Patients: body weight greater than 100 kg. * Patients: current or recent participation, within the last 3 months, in other rehabilitation programs or interventions that could affect study results. * Patients: alcohol or substance dependence that could compromise safety during training sessions. * Patients: unstable health conditions that could make use of the 3DoF Platform and/or head-mounted display unsafe or inappropriate, such as severe cardiovascular disease, severe respiratory disease, or other unstable medical conditions. * Healthy volunteers: health conditions that could make use of the 3DoF Platform and/or head-mounted display unsafe or inappropriate, such as severe cardiovascular disease, severe respiratory disease, or other unstable medical conditions. * Healthy volunteers: any motor disability.
