Which of the following concepts relates to the ability to directly access physical therapy services without a physician's referral?

The concept that relates to the ability to directly access physical therapy services without a physician's referral is known as direct access. This model allows patients to seek physical therapy treatment on their own initiative, bypassing the requirement to first consult a physician for a referral. Direct access can facilitate timelier care, promote patient autonomy, and often lead to improved outcomes as patients can immediately address their physical therapy needs without unnecessary delays. This has become increasingly recognized in many healthcare systems, ensuring that individuals can access the necessary therapies when they recognize the need for them.

In contrast, other concepts like guided therapy often involve structured treatment plans under professional supervision but do not specifically emphasize direct consumer access. Pre-therapy assessment suggests an evaluation before beginning therapy, which may involve referrals. Referral-based access inherently requires a physician's input before treatment can commence, limiting patient autonomy and timely access to care.
