NCT02929758

Brief Summary

The purpose of this prospective, within-subject randomized cross-over design study is to determine if a computer training program (Speed of Processing Training - SOPT) improves safe pedestrian behavior in patients with Parkinson's disease and in healthy older adults in a virtual reality pedestrian environment. Pedestrian injury poses significant risk to healthy older adults and patients with Parkinson's disease. Several age-related changes, including slowing of visual processing speed, increase risky pedestrian behavior. This study will determine if SOPT improves pedestrian behavior in patients with Parkinson's disease and healthy older adults and evaluate the persistence of the SOPT training effects.

Control Initial Training Group

ACTIVE COMPARATOR

Healthy Controls will receive initial SOPT training and will be compared against controls in the delayed training group and the PD subjects in the initial training group

Behavioral: Speed of processing training (SOPT)

Control Delayed Training Group

ACTIVE COMPARATOR

Healthy Controls will receive delayed SOPT training and will be compared against controls in the initial training group and the PD subjects in the delayed training group

Behavioral: Speed of processing training (SOPT)

PD Initial Training Group

OTHER

PD subjects will received initial SOPT training and will be compared against PD subjects in the delayed training group and the control subjects in the initial training group

Behavioral: Speed of processing training (SOPT)

PD Delayed Training Group

OTHER

PD subjects will receive delayed SOPT training and will be compared against PD subjects in the initial training group and the control subjects in the delayed training group

Behavioral: Speed of processing training (SOPT)

Interventions

This is a game-like program designed based on the UFOV. It consists of five activities (Sweep Seeker, Bird Safari, Jewel Diver, Master Gardener, and Road Tour). The duration of training will be 3 months. Participants will be encouraged to train at least three-times weekly for 1-hour blocks and must complete at least 20 training sessions over the course of the three months.

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects with a clinical diagnosis of idiopathic Parkinson's disease based on the presence of bradykinesia and one or both of the following: rest tremor and/or rigidity
  • On stable medications for at least 4 weeks prior to entering the study and expected to not need any medication changes for the duration of the study
  • Age ≥50 at the time of entry into the study
  • Age of onset of Parkinson's disease 45 - 85 years old
  • Asymmetric onset of PD
  • Progressive motor symptoms of PD
  • Hoehn and Yahr stages 1-4
  • Ability to walk up and down a single stair step
  • Access to a computer with internet

You may not qualify if:

  • Atypical features indicative of a Parkinson's Plus disorder (Progressive Supranuclear Palsy, Multiple Systems Atrophy, Corticobasal Degeneration) including cerebellar signs, supranuclear gaze palsy, apraxia, prominent autonomic failure, or other cortical signs.
  • Neuroleptic treatment at time of onset of Parkinsonism
  • Active treatment with a neuroleptic at time of study entry
  • History of multiple strokes with stepwise progression of Parkinsonism
  • History of multiple head injuries
  • Inability to walk without assistance, including a cane, wheelchair, or walker
  • Cognitive dysfunction that would prevent subject's ability to perform virtual reality simulation, speed of processing training, or complete questionnaire
  • Blindness
  • Any medical condition that, based on discretion of the PI, would prevent the subject's ability to participate in the study
  • Age ≥50 at the time of entry into the study
  • On stable medications for at least 4 weeks prior to entering the study and expected to not need any medication changes for the duration of the study
  • Ability to walk up and down a single stair step
  • Access to a computer with internet
  • Parkinson's disease or other neurodegenerative disorder
  • Inability to walk without assistance, including a cane, wheelchair, or walker
  • +3 more criteria
