6-year Follow-up of Dysphagia in Patients With Parkinson's Disease

• Conditions: Parkinson Disease; Dysphagia

• Registration Number: NCT04928079
• Lead Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University

Brief Summary

We recruited 116 patients with idiopathic PD who were from the Neurology clinic of the Second Affiliated Hospital of Zhejiang University, School of Medicine from January 2014 to November 2014. Perform videofluroscopic swallowing study and psychiatric and neurological evaluations and followed up after 6 years.

Detailed Description

In baseline, 116 patients with idiopathic PD were recruited from the Neurology Clinic of the Second Affiliated Hospital of Zhejiang University School of Medicine according to the United Kingdom PD Society Brain Bank Clinical Diagnostic Criteria. They were admitted from January 2014 to November 2014, and were followed up after 6 years.

Perform psychiatric and neurological evaluations. And use Videofluoroscopic swallowing study (VFSS) to assess the swallowing function of PD patients. Added 200mg of barium sulfate to 286ml water to achieve a concentration of 60%. Add a thickener (Ourdiet Swallow, Ourdiet Biotech Co. Ltd, Guangzhou, China) to prepare juice and pudding viscosities, No thickener was added to the liquid viscosity. The patients were advised to have boluses of 3, 5 and 10 ml of the liquid, juice, pudding viscosities in sequence according to the clinician's instructions under X-ray fluoroscopy. The patients ware sitting or standing, The lateral view of the patients' swallow was recorded by a camera (30 frames per second). The radiologist, the clinician, and the rehabilitation therapist completed this examination. Two person analyzed the video in slow motion and frame - by - frame, and record abnormal results. The VFSS inspection parameters are Penetration/aspiration score and Residue score. In order to reduce the influence of drugs on dysphagia, all patients were in the off - period. The patients stopped taking anti-Parkinson's disease drugs from 9 o'clock the night before the examination, and were tested in the morning (free of medicine for more than 12 hours).

The patients had completed the above tests in 2014 and were asked to perform the above assessments again.

Primary Outcome Measures

Name	Time	Method
penetration - aspiration score	in the morning, before taking anti-parkinson drugs	according to the 8-Point Penetration-Aspiration Scale, PAS ≥ 6 means that material enters below the vocal cords.
residue score	in the morning, before taking anti-parkinson drugs	evaluate the residue in the oral cavity and pharynx (vallecula, pyriform sinuses) after the first swallowing. Residue amount was rated on a scale from 0 to 3: no residue visible, 0 score; mild residue (less than 25% of the level of the height of the structure), 1 score; moderate residue (25% to 50% of the height of the structure), 2 score; severe residue (high than 50% of the structure height), 3 score.

Secondary Outcome Measures

Name	Time	Method
water swallow test	in the morning, before taking anti-parkinson drugs	The patient is asked to sit in a chair, and is handed a cup containing 30 mL of water at normal temperature. The patient is then asked to "Please drink this water as you usually do." Time to empty a cup is measured, and the drinking profile and episodes are monitored and assessed.
SDQ-C	in the morning, before taking anti-parkinson drugs	The Chinese version of the Swallowing Disturbance Questionnaire
