Task-Contingent Persistence is Related to Better Performance-Based Measures in Patients with Chronic Musculoskeletal...

Area of Science:

• Rehabilitation Medicine
• Pain Management
• Occupational Therapy

Background:

• Activity patterns, including pacing, avoidance, and overdoing, are behavioral strategies used by individuals with chronic pain.
• The influence of these activity patterns on patient functioning, particularly in daily life tasks, remains a subject of ongoing research and debate.

Purpose of the Study:

• To investigate the impact of different activity patterns on the performance of common lifting tasks within the context of a Functional Capacity Evaluation (FCE).
• To determine how behavioral strategies like persistence, pacing, and avoidance relate to physical performance in patients with chronic pain.

Main Methods:

• A monocentric observational study involving patients undergoing Functional Capacity Evaluation (FCE).
• Assessment of activity patterns using the Patterns of Activity Measures-Pain (POAM-P) tool, measuring avoidance, pacing, and persistence.
• Quantification of maximal safe performance in standardized lifting and carrying tasks as per FCE guidelines.
• Statistical analysis using multiple linear regression models, adjusting for sociodemographic and clinical confounders.

Main Results:

• Task persistence demonstrated a significant positive association with performance across all four measured FCE lifting tests.
• Pacing exhibited a negative influence specifically on the dominant-hand carrying test.
• Avoidance was not found to have a significant impact on any of the assessed FCE lifting tasks.

Conclusions:

• The findings indicate that a task-persistence behavioral pattern is positively correlated with enhanced physical performance in Functional Capacity Evaluations.
• Pacing as an activity pattern may negatively affect performance in certain functional tasks, suggesting a need for careful consideration in rehabilitation strategies.
• Understanding and addressing specific activity patterns can be crucial for improving functional outcomes in patients with chronic pain.
