Physical Therapy Assessment

A physical therapist will initially conduct a subjective examination (interview) of a patient's medical history, and then go on to the objective assessment (physical examination). The subjective examination is guided by the presenting system and complaint, and the objective assessment is in turn guided by the history.

This semi-structured process is used to rule out serious pathology (so called red flags), establish functional limitations, establish the diagnosis, guide therapy, and establish a baseline for monitoring progress. As such, the objective exam will then use certain quantifiable measurements to both guide diagnosis and for progress monitoring. These depend upon the system (and area) being managed, e.g. a musculoskeletal exam may involve, inter alia, assessment of joint range of motion, muscle power, neurological assessment, motor control, and posture, whilst a cardiopulmonary assessment may involve lung auscultation and exercise physiology testing.

In some countries a physical therapist may order diagnostic imaging tests such as x-rays and MRIs to obtain more information about a patient's presenting condition and determine the treatment plan including referral to other practitioners. Physical therapists may also perform electromyography and nerve conduction testing to aid in the diagnosis of muscle and nerve disorders.
