Smart Wearable Device (gaitQ) That Helps People With Long-term Conditions Affecting Movement: Walk Better

Inclusion Criteria

Eligibility Criteria This research will investigate the impact of the gaitQ product on a sufficiently large cohort of PwP, healthy controls and other potential conditions such as stroke and hip and knee replacements. Inclusion criteria * Participants with long-term conditions affecting movement * Diagnosis of idiopathic Parkinson's disease (UK Brain Bank Criteria) or other appropriate condition-specific scales \[stroke, multiple sclerosis, arthritis or osteoporosis\] * Able to self-report history of daily gait freezing and/or festination for people with PD or gait affected by condition * Able to walk unsupported or using an aid for at least 3 minutes and satisfactory completion of the Canadian PARQ and if over 69 used to carry out this level of exercise * Adult (+18 years old) * Normal or corrected-to-normal vision (Snellen Visual Acuity \> 12/18) or safe to mobilise with support * Montreal Cognitive assessment score \>21 or ability to follow 2-stage commands * Healthy participants * With no long-term conditions affecting movement * Able to walk unsupported or using an aid for at least 3 minutes and satisfactory completion of the Canadian PARQ and if over 69 used to carrying out this level of exercise * Adult (+18 years old) * Normal or corrected-to-normal vision (Snellen Visual Acuity \> 12/18) or safe to mobilise with support * Montreal Cognitive assessment score \>21 or ability to follow 2 stage commands 7.1.2 Exclusion criteria * Participants with long-term conditions affecting movement * Any physical or mental condition affecting the ability to safely participate in this level of activity and capacity to understand testing as demonstrated by ability to safely follow commands and pass the PARQ by the research team. * Cognitive impairment affecting the ability to safely participate and follow instructions * Any injury or disorder that may affect balance (other than Parkinson's or referring primary condition) * Any skin conditions or broken skin in the calf and behind the knee area * Deep brain stimulation or pacemaker implants or other implants that may interfere with the measurement system * Healthy participants * Any physical or mental condition affecting the ability to safely participate in this level of activity and capacity to understand testing as demonstrated by the ability to safely follow commands and pass the PARQ by the research team. * Cognitive impairment affecting the ability to safely participate and follow instructions * Any injury or disorder that may affect balance (other than Parkinson's or referring primary condition) * Any skin conditions or broken skin in the calf and behind the knee area * Deep brain stimulation or pacemaker implants or other implants that may interfere with the measurement system
