# Improve obstacle crossing while walking

**Goal (in five words):** Improve obstacle crossing while walking

**Official Title:** Affordances and Impairments: A Paradigm for Understanding Obstacle Crossing in Parkinson's Disease

**Trial ID:** [NCT06932679](https://clinicaltrials.gov/study/NCT06932679)

## Key Facts

- **Status:** RECRUITING
- **Study Type:** OBSERVATIONAL
- **Sponsor:** University of Haifa
- **Target Enrollment:** 180 participants
- **Start Date:** 2025-04-24
- **Completion Date:** 2028-04-24
- **Conditions:** Parkinson's Disease (PD)
- **Interventions:** Assessment of Gait and Visual Exploration
- **Intervention Types:** OTHER

## Summary For Families

The goal is to understand how people with Parkinson's plan and execute stepping over obstacles, by looking at how movement abilities and visual exploration combine to make crossing safe or risky. Rather than testing a drug, researchers will record gait and where participants look as they approach and step over obstacles, comparing people with PD to healthy peers to pinpoint specific walking or visual strategy differences. Findings could help design training, cues, or devices to reduce trips and falls. The study is enrolling adults 20 to 80 who can walk outdoors without aids, with PD participants needing a confirmed diagnosis and no freezing of gait; severe uncorrectable vision problems, major cognitive impairment, or orthopedic issues that affect walking exclude people.

## Eligibility

- **Minimum age:** 20 Years
- **Maximum age:** 80 Years
- **Sex:** ALL

### Full Criteria

```
Inclusion Criteria:

* Participants aged 20 to 80 years.
* Ability to walk independently outdoors without assistive devices.
* For Parkinson's Disease (PD) group: Diagnosis of PD confirmed by medical records.
* For healthy control groups: No neurological or orthopedic conditions affecting gait.

Exclusion Criteria:

* Feezing of gait (for PD group only), based on a score greater than 0 on the Freezing of Gait Questionnaire.
* Severe visual impairment that cannot be corrected with glasses or lenses.
* Cognitive impairment, defined as a score below 18 on the telephone-based Mini-Mental State Examination (MMSE).
* Any orthopedic condition, pain, or other medical condition that may affect walking, based on self-report.
