Although the literature review indicates that plantar pressure may be related to freezing, there are not enough studies examining the effect of freezing phenomenon on pedobarographic pressure distribution and gait parameters. Therefore, the aim of our study is to examine the effect of freezing phenomenon on gait parameters and pedobarographic pressure distribution in patients with Parkinson's Disease.

Individuals diagnosed with Idiopathic Parkinson's disease by a physician and healthy individuals with similar demographic characteristics will be included in the study. Individuals will be examined in 3 groups: a group of patients with Parkinson's Disease with freezing phenomenon, a group of patients with Parkinson's Disease without freezing phenomenon, and a healthy control group.

Inclusion Criteria:

• Volunteering to participate in the study
• Being between stage 2-3 according to the Modified Hoehn-Yahr Staging Scale
• Having a score of 24 or above from the Standardized Mini Mental Test

Exclusion Criteria:

• Presence of an additional neurological or psychiatric disease other than Parkinson's disease
• Presence of uncontrollable dyskinesia or motor fluctuations
• Presence of postural hypotension, vision problems (that cannot be compensated with the correct lens) or vestibular disorders that may affect balance
• Presence of cardiopulmonary diseases that may affect walking
• Presence of orthopedic problems and inflammatory arthritis (such as fractures, osteoporosis, osteomyelitis) that may cause limitation of movement and affect gait and evaluations
