The main focus of this study is on the walking task within the app's version 1.0 build 7. Participants were required to walk unassisted for approximately 20 seconds in a straight line, followed by a 30-second period of standing still, and then returning with 20 seconds. The smartphone's accelerometer and gyroscope captured three-dimensional (3D) rotation data (x, y, z) during these movements, with the device placed in the participant's pocket or bag. A convolutional neural network was applied to the movement dataset to assess confirmed PD cases, utilizing accelerometer and gyroscope readings during outward walking, return walking, and rest periods. |\n| --- |\n| KEYWORDS: Parkinson’s, artificial intelligence, movement, memory |\n\n[https://doi.org/10.25071/2817-5344/55](https://doi.org/10.25071/2817-5344/55)  \n* Corresponding Author-Email Address: emmarichard@cmail.carleton.ca Received 10 June 2023; Received in revised form 03 Aug 2023; Accepted 12 Aug 2023 © 2023 The Author(s) .

It mainly affects older adults and is less common for people under 40 years old, and it is the second most common neurodegenerative disorder.2 If you are diagnosed with PD under 40 years old it is considered early onset and it tends to be because of genetics.3 The main risk factors related to PDare aging, genetics, and exposure to chemicals in the environment.4 A known environmental risk factor is exposure to the pesticide paraquat, which is used to control weeds.5 There have been animal models that show similar pathology to PD when they are exposed toparaquat. These models would show animals having an increase in anxiety one-week post-treatment and impaired motor skills 3 weeks post-treatment.6 There are other neurodegenerative diseases that are similar to PD, such as Dementia with Lewy Bodies or Multiple System Atrophy, but what separates PD is the tremor at rest, rigidity, slowed movement, and poor posture.7 There are about 60,000 new cases of PD diagnosed each year and 7-10 million people are affected worldwide.8 When diagnosing PD, it is mainly based on the symptoms because there are no definitive tests to classify it.9 It can be expensive to diagnose PD because doctors have to eliminate other neurological diseases to correctly diagnose the patient with PD, this can take hours to days.10 PD typically starts with non-motor symptoms such as depression or anxiety and progresses into the patient having motor symptoms such as slowed movement or akinesia.11 The later stages of PD can result in the patient having dementia due to the degradation of the midbrain.12  \nReleased in 2016, Sage Bionetworks created a mobile iOS app called mPower to allow people with or without PD to measure their cognitive and physical capabilities.
