Direct access — the patient/client directly asks the physical therapist to provide services (the patient refers themselves) and the physical therapist freely decides his conduct and takes full responsibility for it. 
Also, the physical therapist has direct access to patients/clients and determines those that need a physical therapy assessment/intervention without referral from a third party.
