1. APTA HOUSE OF DELEGATES POLICYAPTA website: APTA Leadership; Policies & Bylaws, Section I POSITION ON EXCLUSIVE USE OF PHYSICAL AGENTS / MODALITIES - HOD 06-95-29-18 It is the position of the American Physical Therapy Association (APTA) that physical agents/modalities should be utilized only as a component of patient management. Without documentation which justifies the necessity of the exclusive use of physical agents/modalities, the use of physical agents/modalities, in the absence of other skilled therapeutic or educational interventions, should not be considered physical therapy.

2. Electricity Knowledge Map

3. Identifying type, form, and descriptive characteristics

4. Descriptive Characteristics of Pulsed and Alternating Currents Phases � number of; applies to Pulsed Current only Symmetry � are the phases mirror images? (size and shape) Balance � is the area under each [+] and [-] phase equal? (represents amount of charge) Shape � descriptive only; �square, spike, sinusoidal, exponential, etc..�
