# Characterize freezing of gait episodes

**Goal (in five words):** Characterize freezing of gait episodes

**Official Title:** An International Multimodal Protocol for Assessing Freezing of Gait in Individuals Living with Parkinson's Disease

**Trial ID:** [NCT06519279](https://clinicaltrials.gov/study/NCT06519279)

## Key Facts

- **Status:** RECRUITING
- **Study Type:** OBSERVATIONAL
- **Sponsor:** Tel-Aviv Sourasky Medical Center
- **Target Enrollment:** 20 participants
- **Start Date:** 2024-10-01
- **Completion Date:** 2025-12
- **Conditions:** PD - Parkinson's Disease
- **Interventions:** Opals, Axivity
- **Intervention Types:** DEVICE

## Summary For Families

The project aims to improve detection and measurement of freezing of gait, the sudden brief inability to step that many people with Parkinson's experience. It uses small wearable motion sensors called Opal and Axivity to record detailed limb and trunk movement and automatically identify and quantify freezing episodes during clinic tests and in daily life, the sensors only collect movement data and do not interact with levodopa or other drugs, though participants may be asked to briefly delay their morning Parkinson's medication. Adults 18 and older with idiopathic Parkinson's who can walk 10 meters unaided, have no deep brain stimulator, and have had stable Parkinson's meds for at least 4 weeks can join, with those who have freezing needing a score of 1 or more on the New Freezing of Gait Questionnaire; recent major cardiac events, active cancer treatment, certain severe medical or psychiatric conditions, pregnancy, or unwillingness to delay morning meds exclude someone.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL

### Full Criteria

```
Inclusion Criteria:

1. Diagnosis of idiopathic Parkinson's disease (PD) made by a neurologist according to the Movement Disorders Society guidelines;
2. Able to walk independently for a distance of 10 meters, without walking aid;
3. Absence of a Deep Brain Stimulator;
4. Stable PD treatment in the 4 weeks prior to participation that is not expected to change in the course of the study.
5. For patients with FOG: a score of ≥ 1 on the New Freezing Of Gait Questionnaire (NFOG-Q).

Exclusion Criteria:

1. Occurrence of any of the following within 3 months prior to informed consent: myocardial infarction, hospitalization for unstable angina, stroke, coronary artery bypass graft (CABG), percutaneous coronary intervention (PCI), implantation of a cardiac resynchronization therapy device (CRTD), active treatment for cancer or other malignant disease, uncontrolled congestive heart disease (NYHA class \>3), acute psychosis or major psychiatric disorders or continued substance abuse, other neurological (than PD) or orthopaedic impairment that significantly impacts on gait.
2. Unwilling to temporarily delay the morning anti-Parkinsonian medication.
3. Preganacy and
