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.
A valid contract is a written or expressed agreement between two parties to provide a product or service. A void contract is missing an element. In a voidable contract, there is an option for the parties to enforce the terms even though an element is missing, or some other issue exists with the terms.
