Physical therapy experts evaluate whether examination, evaluation, plan of care, intervention selection, supervision, and documentation met the accepted standard of care in outpatient, inpatient, home health, and skilled nursing settings. Entry to practice in the United States requires a Doctor of Physical Therapy degree from a program accredited by the Commission on Accreditation in Physical Therapy Education, followed by a state licensure examination 12. That examination is the National Physical Therapy Examination, administered by the Federation of State Boards of Physical Therapy, with separate versions for physical therapists and physical therapist assistants; each licensing authority sets its own eligibility criteria for licensure and for the exam 3. Because scope, supervision rules, and direct access provisions vary substantially by state, the applicable state practice act — and the licensing authority that administers it — is always a threshold document in these cases 6.
The most common claims involve injury during treatment. Falls in the clinic or during gait training generate a large share of the litigation, and the analysis turns on the documented fall risk assessment, whether a gait belt and appropriate assistance level were used, whether the patient was left unattended on equipment, and whether the assignment matched the patient's demonstrated tolerance that day. Manual therapy claims address the force and technique used, with cervical manipulation and mobilization producing the most serious allegations. Aggressive range-of-motion work after surgery generates fractures, dislocations, and repair failures, and those cases are usually litigated against the operating surgeon's written post-operative protocol, which sets the weight-bearing status, range limits, and timeline the therapist was obligated to follow.
A second cluster involves the therapist's independent diagnostic responsibility. Because most states now permit some degree of direct access, physical therapists frequently see patients who have not been medically screened, which makes failure to recognize red flags and refer a recurring theme: cauda equina syndrome, deep vein thrombosis, spinal cord compression, fracture, infection, cardiac symptoms during exertion, and neoplasm presenting as musculoskeletal pain. The APTA Guide to Physical Therapist Practice describes the profession's own framework for examination and evaluation and for diagnosis, prognosis, intervention, and outcomes, and is commonly used to frame what a competent screening examination should have included 4.
Modality and equipment claims are smaller in number but often clean on liability. Burns from superficial and deep heat, electrical stimulation, and ultrasound; skin injury from ice and contrast baths; and injuries involving traction, parallel bars, treadmills, and therapeutic equipment usually resolve into questions of parameter selection, patient positioning, sensation testing before application, and supervision during the modality. Documentation is central because the parameters used are supposed to be recorded.
Supervision and delegation form the final major category and are frequently the most productive theory against an institutional defendant. Cases turn on what was delegated to a physical therapist assistant or an unlicensed aide, whether that delegation was permitted under the state practice act, whether the required level of supervision was actually provided, and whether the supervising therapist reassessed the patient at the intervals the state and the payer require. Related disputes address billing and documentation — whether the units billed reflect the time and skilled service actually delivered, and whether the plan of care was certified and recertified — which arise in both civil litigation and licensing board proceedings. Where the specific practice area is contested, board certification through the APTA specialist certification program governed by the American Board of Physical Therapy Specialties, available in areas including orthopaedics, sports, neurology, geriatrics, pediatrics, cardiovascular and pulmonary, oncology, clinical electrophysiology, pelvic and women's health, primary care, and wound management, is the credential to look for 5.
Entry to physical therapist practice in the United States requires a Doctor of Physical Therapy degree from a CAPTE-accredited program plus a state licensure examination — but scope, supervision of assistants, and direct access provisions are set state by state, so the applicable practice act is always the threshold document.

FAQ
A qualified expert should hold a DPT from a CAPTE-accredited program, an active unrestricted license, and current practice in a setting comparable to the one at issue. Board certification through the APTA specialist certification program governed by the ABPTS — in orthopaedics, sports, neurology, geriatrics, or another recognized area — materially strengthens the opinion, as does demonstrated familiarity with the specific state practice act in the jurisdiction where the care was delivered.
These experts are retained in patient fall cases, manual therapy and mobilization injury claims, post-surgical protocol violations, failure-to-refer cases, modality burns, and supervision and delegation disputes involving assistants and aides. They also appear in billing and documentation matters, licensing board proceedings, and damages work assessing future rehabilitation needs.
Yes, and that duty has become more prominent as direct access has expanded, because therapists increasingly see patients who have not been medically screened first. Recurring failure-to-refer claims involve cauda equina syndrome, deep vein thrombosis, spinal cord compression, undiagnosed fracture, infection, cardiac symptoms provoked by exercise, and cancer presenting as musculoskeletal pain. The APTA Guide to Physical Therapist Practice sets out the profession's own framework for the examination and evaluation that should have surfaced those findings.
Usually by putting the surgeon's written protocol next to the therapy notes. The protocol sets weight-bearing status, range-of-motion limits, and a timeline; the daily notes record what was actually performed and at what resistance. Where the notes document motion or loading outside the protocol before the authorized date, the causation question narrows considerably — and where the notes are silent, the adequacy of documentation itself becomes an issue.
It depends on the state practice act and on what supervision was actually provided. The analysis asks whether the task was one that could lawfully be delegated to an assistant or an unlicensed aide in that jurisdiction, whether the required level of supervision — direct, on-site, or general — was in place, and whether the supervising therapist reassessed the patient at the required intervals. Because those are institutional practices as much as individual ones, these claims often reach the employer as well.
In general, expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic and testimony experience, relevant certifications, case-type specialization, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
