Why is multipulse stimulation necessary during procedures?

Multipulse stimulation is particularly essential during procedures to ensure that adequate stimulation is delivered to reach the motor threshold. This is important because achieving the motor threshold is crucial for eliciting a strong and reliable muscular response. In certain clinical settings, a single pulse may not provide the necessary intensity or duration of stimulation to activate motor neurons effectively. By using multipulse stimulation, clinicians can ensure that the cumulative effect of multiple stimulations helps reach the desired threshold, thereby maximizing the likelihood of obtaining meaningful motor responses. This technique is often used in rehabilitation, diagnostics, and therapeutic interventions where precise control of muscle activation is required.

Enhancing muscle tone, generating I waves, and improving sensory responses can be relevant in specific contexts, but the primary reason for employing multipulse stimulation is fundamentally linked to ensuring that the stimulation exceeds the motor threshold, allowing for effective muscle contraction and response.
