An Overview of Physical Therapy

Physical therapy is a healthcare specialty that includes the evaluation, assessment, and treatment of individuals with limitations in functional mobility. Physical therapy services are provided by physical therapists, who are professionals licensed by the state in which they work. Physical therapists (or PTs, as they are commonly called) are required to have a master's degree or a clinical doctorate degree from an accredited institution and must sit for a licensing exam to practice.

They are trained to assess your condition and help you regain maximal functional mobility and independence.

Physical therapists use a variety of treatment modalities and techniques to help you move better and feel better; treatment is very personalized. Choosing physical therapy has been shown to help you recover quickly and safely, and it can save you money due to decreased overall healthcare costs.

Do I Need Physical Therapy?

How do you know if you require the skilled services of a physical therapist? If you have an injury or illness that results in pain, physical impairment, or limited normal movement/loss of function, a physical therapist can help. Physical therapists treat people across the entire lifespan. Many PTs specialize in treating a certain population, like children, the elderly, or athletes. Regardless of age, if you have impaired mobility, a physical therapy evaluation may be warranted to offer treatment and a strategy to improve function.

Some common problems that physical therapists evaluate and treat include:

Know, however, that physical therapists can treat many other problems besides the ones listed. Be sure to speak with your doctor if you feel you may benefit from this treatment.

 When an injury or illness occurs that limits your ability to move about safely or normally, a referral to a physical therapist may be made. Physical therapists work closely with patients, doctors, and family members to ensure safe and rapid return to maximal function.

Physical therapists can also help you prevent injury or loss of functional mobility. Your PT can analyze your movements before you are injured and offer strategies to help keep you healthy and moving well. Some physical therapists work with athletes to help keep them on the playing field and out of the rehab clinic, for example.

Where Will I Get My Physical Therapy?

Physical therapists work in a variety of different settings. Anywhere you may encounter a person who may be having difficulty with normal mobility is where you may find a physical therapist, including:

  • In the hospital
  • In nursing homes
  • In outpatient clinics
  • With sports teams
  • In schools (many state laws require that children receive services in the setting that is most familiar to them and/or that allows them to stay on track with their peers)

Preparing for Physical Therapy

When you are preparing for physical therapy, there are a few things you can do to ensure you have a positive experience. First, ask questions before choosing a physical therapist. Some PTs are clinical specialists; finding one who specializes in treating your specific problem can help. You should ask about insurance coverage, a cancellation or no-show policy, and what you should wear to your PT appointment.

Your physical therapist should work with you to set specific goals, so be prepared to tell your physical therapist exactly what you hope to achieve during therapy. If you don't understand a specific treatment that is occurring during your PT sessions, ask. Your relationship with your physical therapist should feel like a therapeutic alliance, with both of you working together to achieve specific goals.

Evaluation By a Physical Therapist

When you first visit a physical therapist, he or she will evaluate and assess your overall condition. He or she may take specific measurements to gather information about your illness or injury. Impairments typically measured may include:

  • Strength
  • Range of motion
  • Flexibility
  • Balance
  • Joint mobility
  • Neurological function
  • Pain
  • Cardiac function
  • Pulmonary function
  • Overall functional mobility

After gathering information about your injury or illness, your PT will make a prognosis of your condition and can offer strategies to help you move better and feel better. He or she will discuss your goals for physical therapy and work with you to develop a treatment plan for your rehab.

What Happens During Physical Therapy Treatments?

Physical therapists use many different techniques to help you decrease pain and stiffness, improve motion and strength, and improve mobility. Physical agents such as heat, ice, ultrasound, or electrical stimulation may be used. Manual techniques are often used to help improve mobility.

Therapeutic exercise is often used by physical therapists to help people gain range of motion, increase strength, and improve function. Patient education about a condition or illness is paramount to the practice of physical therapy, and therapists may use charts, models, and diagrams to help you understand your diagnosis and prognosis.

You may also be given modifications to make or exercises to do at home.

A Word From Verywell

It's natural to feel some anxiety when first going to physical therapy. What will happen? Will therapy hurt? These feelings typically quickly go away once you meet your physical therapist and get working on your rehab goals. By understanding what your physical therapist can do to help you, you can have realistic expectations about your rehab and a positive outcome with your physical therapy experience.
