Logbook sPAV

Abstract

The Logboek sPAV (Logbook for Symptomatic Peripheral Arterial Disease) is a standardized monitoring tool designed to facilitate the transition of patients from supervised clinical treatment to independent, active self-management of their condition. The primary goal is to encourage the development of an active lifestyle crucial for managing symptomatic sPAV, often characterized by intermittent claudication. This logbook allows the patient to meticulously record the details of their self-administered training program. Crucially, it provides the physiotherapist with the necessary data to evaluate and control the patient’s training progression, load, and adherence following the intensive phase of physical therapy.

Authors

The Dutch version of the Logboek sPAV is derived from and officially endorsed by the KNGF-richtlijn Symptomatisch perifeer arterieel vaatlijden (KNGF Guideline for Symptomatic Peripheral Arterial Disease), developed by the Koninklijk Nederlands Genootschap voor Fysiotherapie (KNGF).

Purpose

The fundamental purpose of the Logboek sPAV is two-fold: to promote patient autonomy and to ensure clinical oversight of long-term rehabilitation. For patients suffering from symptomatic sPAV, maintaining a structured, active training routine is essential for improving walking distance and quality of life. The logbook serves as the structured mechanism for patients to track key metrics of their independent exercise program, such as distance, duration, frequency, and symptom intensity (e.g., claudication pain scores).

For the clinician, the logbook transforms the patient’s independent exercise into actionable, quantifiable data. This enables the physiotherapist to objectively assess adherence to the prescribed training load, identify potential issues in progression, and make necessary adjustments to the program, thereby ensuring the continuity and effectiveness of the therapeutic goals established during supervised exercise therapy (SET).

Construct

The Logboek sPAV primarily measures Behavioral Adherence and Physical Activity Volume in the context of chronic disease self-management. While not a psychological scale in the traditional sense, it captures personal factors related to commitment and consistency in following a prescribed rehabilitation protocol.

Specifically, the logbook captures data points related to:

• Activity and Mobility: Tracking the frequency, duration, and distance of walking or other prescribed exercises.
• Training Load and Progression: Monitoring how the exercise intensity changes over time, including pain thresholds or rest periods required.
• Personal Factors: Implicitly assessing the patient’s motivation and ability for self-management outside the clinical setting.

Validity

As a clinical monitoring tool derived directly from the KNGF Guideline for Symptomatic PAD, the Logboek sPAV’s validity rests largely on its Face Validity and Clinical Utility within the established framework of Dutch physical therapy practice. It is designed to capture the specific metrics (e.g., distance walked, pain onset) that are clinically relevant for monitoring the progression of intermittent claudication.

Dedicated, large-scale psychometric studies establishing construct or criterion validity specifically for the logbook itself (as distinct from the underlying clinical protocols) are typically not performed for guideline-based tracking instruments of this nature. Its validity is therefore inherent in its function as a standardized, systematic record-keeping method compliant with national clinical standards.

Reliability

The reliability of the data collected by the Logboek sPAV depends heavily on the patient’s ability and willingness to provide accurate and consistent self-reporting. While the instrument structure is standardized, the reliability is primarily assessed through Inter-rater Reliability (the consistency with which different physiotherapists interpret the logged data) and the inherent consistency of the patient’s entries over time.

Given its clinical origin, test-retest reliability in a traditional sense is not applicable, as the instrument tracks behavior over time, which is expected to change. However, the structured format ensures high Internal Consistency in the types of data points recorded (e.g., always recording distance and pain score for each session), enhancing the reliability of the resulting activity profile.

Factor Analysis

Factor analysis is not applicable to the Logboek sPAV. This instrument serves as a descriptive logbook for tracking physical performance variables rather than a multi-item scale designed to measure latent psychological traits. It does not contain discrete items intended for psychometric scaling or dimension reduction analysis.

Instrument

Test Type: Clinical Monitoring Tool / Standardized Questionnaire (Logbook)

Format: Self-administered paper or digital logbook for daily or session-based recording.

Language Available: Dutch (Nederlandse versie).

Population Group: Patients diagnosed with Symptomatic Peripheral Arterial Disease (sPAV).

Age Group: Adults, Older Adults (Volwassenen, Ouderen).

Population Details: Individuals undergoing or having completed supervised physical therapy for sPAV, focusing on improving mobility and managing symptoms related to the lower extremities (Onderste extremiteit).

Test Methodology: Patients record specific exercise metrics (distance, time, pain scores) following each independent training session. The data is reviewed periodically by the physiotherapist to adjust the therapeutic plan.

Permissions & Fee and Test Year

The Logboek sPAV is derived from the publicly accessible KNGF clinical guideline, implying that the instrument is generally available for use by authorized healthcare professionals (specifically physiotherapists) adhering to the guideline standards in the Netherlands. Specific fees for usage or licensing are typically waived for clinical tools integrated into national professional guidelines, although reproduction costs may apply. The test year aligns with the most recent publication or revision date of the KNGF Guideline for Symptomatic Peripheral Arterial Disease.

Items of the Logboek sPAV

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

The source content provided does not list the specific items contained within the Logboek sPAV. However, based on its function as a monitoring tool for exercise in symptomatic PAD, the logbook typically requires patients to record the following categories of information for each session:

• Datum van training (Date of training)
• Soort activiteit (Type of activity – e.g., walking, cycling)
• Afstand afgelegd (Distance covered – usually in meters or kilometers)
• Tijd besteed aan training (Time spent training – usually in minutes)
• Claudicatio pijnscore bij aanvang (Claudication pain score at onset – often using a VAS or similar scale)
• Maximale loopafstand (Maximum walking distance achieved)
• Opmerkingen/Bijzonderheden (Notes/Specific observations)
