Physical agents and modalities are often used by your physical therapist to augment your therapy and to help achieve rehab goals. They may be used to decrease pain and inflammation. Exercises may be prescribed to help improve endurance, strength, or range of motion. Your physical therapist should be prepared to explain to you the reason for using each therapeutic modality and what to expect from each treatment.
How does joint mobilization work?
Joint mobilization occurs when your physical therapist passively moves the joints of your body in specific directions. This can help to decrease pain and improve mobility. 5 While we often think of our joints moving as hinges, there is a gliding motion that also occurs between the joints of the body. This gliding motion is increased during joint mobilizations. The degree to which your therapist moves each joint depends on the amount of pressure and the direction of force applied to the joint.
What is ultrasound treatment?
Ultrasound is a deep heating treatment used to treat many musculoskeletal conditions like sprains, strains, or tendonitis. 1 Ultrasound is administered by your physical therapist using an ultrasound machine. A wand called a sound head is pressed gently against your skin and moved in small circular sweeps near the site of injury. A small amount of gel is used so the ultrasound waves are absorbed into the skin and muscles.

Why is physical rehabilitation necessary?
If you have suffered an injury, undergone certain types of surgery, or experience physical limitations due to aging or underlying health conditions, physical rehabilitation may be necessary to restore the body to optimal form and function.
What is the next step in physical rehab?
Once your range-of-motion has been restored as best as possible, the next stage of physical rehab is to start restoring strength. Resting during the Recovery Stage can cause muscular atrophy or wasting that leads to weakness and loss of endurance. In the Strength Stage, the goal is to minimize these losses and work back to pre-injury levels of muscular strength and endurance, along with cardiovascular endurance. With the use of weight machines, strength training can be done safely and precisely while reducing the risk of aggravating injuries – or risking new ones. This is an incredible advantage and makes them great tools for rehabilitation.
What is the final step in rehabilitation?
The final step or the rehab process is to work towards restoring function . In order to effectively restore a patient to pre-injury levels of function, it’s important to address higher-level capabilities in order to reduce the risk of re-injury. Effective treatment will identify any deficiencies in these capabilities, determine how significant these deficiencies are, and work up methods to bring these capabilities back up to pre-injury levels. These capabilities may include:
What is the first stage of physical rehabilitation?
The first stage of physical rehabilitation is the Recovery Stage. This is the most important stage of the treatment process and, depending on the severity of your injuries, can also be the longest.

What are the four types of information gathering activities in the diagnostic process?
The committee identified four types of information-gathering activities in the diagnostic process: taking a clinical history and interview; performing a physical exam; obtaining diagnostic testing; and sending a patient for referrals or consultations.
How does the diagnostic process work?
Once a patient seeks health care, there is an iterative process of information gathering, information integration and interpretation, and determining a working diagnosis. Performing a clinical history and interview, conducting a physical exam, performing diagnostic testing, and referring or consulting with other clinicians are all ways of accumulating information that may be relevant to understanding a patient's health problem. The information-gathering approaches can be employed at different times, and diagnostic information can be obtained in different orders. The continuous process of information gathering, integration, and interpretation involves hypothesis generation and updating prior probabilities as more information is learned. Communication among health care professionals, the patient, and the patient's family members is critical in this cycle of information gathering, integration, and interpretation.
What is the importance of clinical history?
Acquiring a clinical history and interviewing a patient provides important information for determining a diagnosis and also establishes a solid foundation for the relationship between a clinician and the patient. A common maxim in medicine attributed to William Osler is: “Just listen to your patient, he is telling you the diagnosis” (Gandhi, 2000, p. 1087). An appointment begins with an interview of the patient, when a clinician compiles a patient's medical history or verifies that the details of the patient's history already contained in the patient's medical record are accurate. A patient's clinical history includes documentation of the current concern, past medical history, family history, social history, and other relevant information, such as current medications (prescription and over-the-counter) and dietary supplements.
What is a working diagnosis?
The working diagnosis may be either a list of potential diagnoses (a differential diagnosis) or a single potential diagnosis. Typically, clinicians will consider more than one diagnostic hypothesis or possibility as an explanation of the patient's symptoms and will refine this list as further information is obtained in the diagnostic process. The working diagnosis should be shared with the patient, including an explanation of the degree of uncertainty associated with a working diagnosis. Each time there is a revision to the working diagnosis, this information should be communicated to the patient. As the diagnostic process proceeds, a fairly broad list of potential diagnoses may be narrowed into fewer potential options, a process referred to as diagnostic modification and refinement (Kassirer et al., 2010). As the list becomes narrowed to one or two possibilities, diagnostic refinement of the working diagnosis becomes diagnostic verification, in which the lead diagnosis is checked for its adequacy in explaining the signs and symptoms, its coherency with the patient's context (physiology, risk factors), and whether a single diagnosis is appropriate. When considering invasive or risky diagnostic testing or treatment options, the diagnostic verification step is particularly important so that a patient is not exposed to these risks without a reasonable chance that the testing or treatment options will be informative and will likely improve patient outcomes.
How to obtain a clinical history?
The National Institute on Aging, in guidance for conducting a clinical history and interview, suggests that clinicians should avoid interrupting, demonstrate empathy, and establish a rapport with patients (NIA, 2008). Clinicians need to know when to ask more detailed questions and how to create a safe environment for patients to share sensitive information about their health and symptoms. Obtaining a history can be challenging in some cases: For example, in working with older adults with memory loss, with children, or with individuals whose health problems limit communication or reliable self-reporting. In these cases it may be necessary to include family members or caregivers in the history-taking process. The time pressures often involved in clinical appointments also contribute to challenges in the clinical history and interview. Limited time for clinical visits, partially attributed to payment policies (see Chapter 7), may lead to an incomplete picture of a patient's relevant history and current signs and symptoms.
What is diagnostic in health care?
Diagnosis has been described as both a process and a classification scheme, or a “pre-existing set of categories agreed upon by the medical profession to designate a specific condition” (Jutel, 2009).1 When a diagnosis is accurate and made in a timely manner, a patient has the best opportunity for a positive health outcome because clinical decision making will be tailored to a correct understanding of the patient's health problem (Holmboe and Durning, 2014). In addition, public policy decisions are often influenced by diagnostic information, such as setting payment policies, resource allocation decisions, and research priorities (Jutel, 2009; Rosenberg, 2002; WHO, 2012).
Why is information gathering important in the diagnostic process?
It is important to note that clinicians do not need to obtain diagnostic certainty prior to initiating treatment; the goal of information gathering in the diagnostic process is to reduce diagnostic uncertainty enough to make optimal decisions for subsequent care (Kassirer, 1989; see section on diagnostic uncertainty). In addition, the provision of treatment can also inform and refine a working diagnosis, which is indicated by the feedback loop from treatment into the information-gathering step of the diagnostic process. This also illustrates the need for clinicians to diagnose health problems that may arise during treatment.
