Which training approach aims to desensitize the pain generator and build tolerance for load through simple functional movements while addressing mobility and stability dysfunctions?

• A. Block retraining
• B. Random retraining
• C. Primary load management
• D. Secondary load management

Answer: (B)

Desensitizing the pain response and building tolerance to loading works best when practice is varied and functional, rather than repetitive and fixed. This approach uses simple, everyday movements and changes in task difficulty or load to expose the nervous system to a range of stimuli, helping it recalibrate pain sensitivity while gradually increasing what you can tolerate. By weaving in movements that challenge mobility and stability, the training addresses how joints and muscles move together, not just isolated tissues, so the patterns become more robust and transferable to daily activities.

Because the tasks are varied and progressively loaded, you reduce fear and sensitization and promote better motor control across different movement demands. In contrast, repeating the same movement under the same conditions—block training—tends to fix you to a single pattern and load, which is less effective for broader desensitization and for developing tolerance across a range of tasks. Reducing load to the painful area or focusing mainly on related structures without this varied exposure doesn’t cultivate the same generalizable tolerance.
