Recruitment Threshold
Minimum stimulation intensity required to activate a sufficient population of neural fibers to produce therapeutic effect.
Full Definition
Recruitment threshold represents the point at which electrical stimulation begins to activate enough neural fibers to generate a therapeutic response. Below this threshold, stimulation may be imperceptible or ineffective, while exceeding it recruits additional fibers and potentially increases therapeutic benefit. Understanding recruitment thresholds is essential for optimizing stimulation parameters and explaining dose-response relationships in neuromodulation therapy.
Usage
Usage note: Technical concept requiring quantitative documentation of threshold values.
