Rationale: Clinical practice guidelines summarise the existing evidence on specific health conditions and aim to optimise quality of care by providing evidence-based recommendations. Studies have reported a gap between research findings and clinical practice in physiotherapy. Guideline adherence is often used as a measure of agreement between therapeutic care and guideline recommendations.

Background: Pain fluctuations are a characteristic phenomenon in advanced Parkinson's disease (PD), but their temporal association with motor and non-motor symptom (NMS) fluctuations remains largely enigmatic. Moreover, data on their importance for disease severity perception and health-related quality-of-life (hr-QoL) is limited.

Objective: To dissect pain fluctuations with respect to pain type and frequency patterns, and their association with motor and non-motor fluctuations.

Advanced Parkinson's disease (PD) is characterized by motor fluctuations including unpredictable oscillations remarkably impairing quality of life. Effective management and development of novel therapies for these response fluctuations largely depend on clinical rating instruments such as the widely-used PD home diary, which are associated with biases and errors. Recent advancements in digital health technologies provide user-friendly wearables that can be tailored for continuous monitoring of motor fluctuations.

Background: The Parkinson Disease (PD) Home Diary (HD) is a commonly used clinical outcome measure, but it has not been extensively compared to direct assessments by experienced observers.

Objective: Validation of patient-reported HD by investigating the agreement between motor state assessments by patients and observers.

Methods: This observational study included patients with PD and motor fluctuations.

The Parkinson's disease (PD) home diary is frequently used in clinical trials to measure efficacy of medical treatments for motor fluctuations in advanced PD. This prospective study in fluctuating PD patients examines the validity of the diary for quantification of motor states in comparison to direct clinical observation. 51 patients (median age: 65 years, disease duration: 11 years) completed the diary half-hourly for two consecutive days and were simultaneously rated by an experienced observer, who independently evaluated motor states half-hourly throughout daytime.
