Physical therapy aides help appointments run smoothly, clean treatment areas, provide customer support and manage clerical duties. The specific tasks of an aide also vary by state. In most cases, unlicensed aides do not provide any direct patient care.
Generally, to be legally valid, most contracts must contain two elements: 1  All parties must agree about an offer made by one party and accepted by the other.  Something of value must be exchanged for something else of value. This can include goods, cash, services, or a pledge to exchange these items.
There are three more elements of a contract that are specific to making the contract legal, like mutuality, capacity and legally acceptable terms. Acceptance, in detail, happens when an offeree agrees to be mutually bound to the terms of a contract. It can be a written acceptance, like a contract for real estate or through a purchase order.
