Step-by-step explanation:
When the PTA assists the patient for <75% but >25% of the patient's total work, this is considered moderate assistance. Moderate assistance means that the patient is able to contribute to their own care, but still requires some help from the PTA. This level of assistance allows the patient to gradually improve their independence while also receiving support.
