About

The purpose of this study is to increase clinical knowledge of the relationship between increased plantar sensory information and orthotics in a Parkinsonian gait. The objectives of this study are to determine if orthotics, with and without a textured top cover, can alter muscle activation, gait parameters, balance, functional mobility, and decrease fall risks in Parkinson's participants.

Full description

The purpose of this study is to increase clinical knowledge of the relationship between increased plantar sensory information and orthotics in a Parkinsonian gait. Observing gait parameters and muscle activation changes, in orthotics with and without a textured top cover, provides an increased understanding of conservative treatment options available to the Parkinson's population. It is hypothesized that balance and functional mobility in Parkinson's Disease (PD) patients will increase, while decreasing fall risks, when wearing both types of orthotics. Larger improvements are expected with the orthotics with a textured top cover, thus increasing plantar sensory feedback. Male and female participants, aged 55-75, with a diagnosis of idiopathic Parkinson's disease can participate in the study. Two types of orthotic design will be examined: 1) Customizable over-the-counter orthotics and 2) Customizable over-the-counter orthotics with a textured top cover. Five different assessments will be performed during three different testing sessions: 1) baseline testing; 2) 6-weeks post-baseline; and 3) 12-weeks post-baseline. The administered assessments include: 1) Static balance, double limb stance; 2) The Berg Balance Scale (BBS); 3) Timed Up and Go (TUG), 4) Functional Gait Assessment (FGA); and 5) Walking task.

20 participants in 2 patient groups

Orthotic
Active Comparator group
Description:
Recruited participants will be asked to wear the customizable foot orthotic, from baseline testing to a follow-up at 6 weeks post-baseline. Outcome measures at 6 weeks will be compared to those at baseline.
Treatment:
Device: Orthotics alone
Orthotic+Textured Top Cover
Active Comparator group
Description:
At 6 weeks post-baseline, participants will received a different orthotic which has a textured material used as its top cover. Testing at 6 weeks post-baseline will determine if acute changes occur as a result of wearing the orthotic with textured top cover. Testing at 12 weeks post-baseline will determine if long-term changes occur as a result of the orthotic with textured top cover.
Treatment:
Device: Orthotics+textured top cover
