Which Sonic device feature allows for customization of treatment plans?

The feature that allows for customization of treatment plans in Sonic devices is the capability for programmable settings based on individual needs. This functionality enables practitioners to tailor the treatment parameters to suit each patient's unique requirements and specific health conditions. By adjusting these settings, clinicians can optimize therapy, ensuring it is effective and personalized, thereby enhancing patient outcomes.

The other choices do not provide the same level of customization. Standard operating procedures offer guidelines but do not allow for individual adjustments for each patient's treatment. Pre-set templates may standardize treatment but lack the flexibility needed for customizing plans, and mandatory session durations can restrict how each treatment is tailored to fit individual patient needs. Thus, programmable settings best encapsulate the principle of personalized care in treatment planning.
