Purpose: Despite the lack of validity and reliability, residency programs use various assessments to admit residents and anticipate their future performance that include admission interviews and letters of recommendation. The purpose of this study is to examine whether there is a valid, reliable, or predictive association between physical therapy r...

Clinical decision-making (CDM) plays an integral role in the work of a physical therapist and has ramifications for patient outcomes and experience. Rational decision-making – acting in a manner that helps us achieve our goals – is influenced by cognitive, emotional, and social variables. The dual process theory helps us understand how clinicians m...

Objective The aims of this study were to 1) compare the dosage of physical therapy provided for patients following an anterior cruciate ligament reconstruction (ACL-R) with either quadriceps or bone-patellar tendon-bone (BPTB) graft type and their resulting outcomes and 2) investigate the frequency therapists documented surgical graft type. Design...

Background Mirror therapy has been studied primarily as an intervention following central sensitization and nociplastic conditions, such as complex regional pain syndrome, post-cerebrovascular accident pain, and phantom-limb pain. Case Presentation This case report is on a 48-year-old female musician treated with physical therapy following a rotat...

Background: An estimated 45% of concussions are reported to be related to motor vehicle collisions (MVC). However, limited research exists involving the treatment of MVC-related concussion, especially when combined with whiplash-associated disorders (WAD). Purpose: The purpose of this case series is to examine the patient response to an irritabili...

Background and Purpose: Resistance training has been shown to improve strength, endurance, and function in healthy older adults. The purpose of this case series was to describe the outcomes of a rehabilitation program consisting of heavy resistance training in older adults for management of hip pain. Case Description: Two male patients, aged 69 an...

Background Current research supports active rehabilitation for individuals recovering from concussion, but does not offer objective thresholds to guide treatment progression. The purpose of this study was to demonstrate the feasibility of utilizing standardized symptom provocation thresholds to guide exercise progression in concussion rehabilitatio...

Background: Concussion management evidence supports the efficacy of gradual active rehabilitation for return to sport in adolescents, however there is paucity of evidence for non-sports-related concussion management. Purpose: The purpose of this case series is to describe the feasibility and practicality of an irritability-based step-by-step model...

Collection and utilization of outcomes data is becoming more commonplace as payers, such as the Centers for Medicare and Medicaid Services, require them for justification and assessment of treatment interventions. In addition to compliance, outcomes measures can provide valuable information about the quality of care provided to patients. Computer a...

Objective: To examine the potential relationship between physical therapy (PT) treatment outcomes and chronicity of low back pain (LBP) in the outpatient setting. Design: Retrospective observational study SETTING: Outpatient physical therapy clinics across 11 states PARTICIPANTS: 11941 patients with LBP provided physical therapy services and dis...

Study design: A retrospective observational study OBJECTIVE.: Assess the time course of functional outcome improvements during a physical therapy (PT) episode of care for patients with low back pain (LBP). In addition, assess the impact of patient variables, such as symptom duration, on the time course of functional outcome improvements. Summary...

Background: Low back pain (LBP) is a leading cause of work absence and may influence the development of fear-avoidance behaviours. The purpose of this case series was to examine the use of cognitive behavioural therapy (CBT) with physical therapy (PT) for the treatment of fear-avoidance behaviours in patients with chronic LBP who are disabled or i...

Study Design: Case Series. Background: Shoulder pain is a prevalent problem in health care. Traditionally, treatment is based on a pathoanatomical diagnosis determined through the use of special tests. The validity of these special tests is questionable and minimal evidence exists to support these tests to guide treatment. The purpose of this case...

Background and purpose: Conservative therapies for complex regional pain syndrome (CRPS) have traditionally focused on exercise and desensitization techniques targeted at the involved extremity. The primary purpose of this case series is to report on the potential benefit of utilizing manual therapy to the lumbar spine in conjunction with tradition...

Study Design Case series. Background Low back pain (LBP) is an increasing problem in health care. The evidence for the use of spinal manipulative therapy to treat pediatric patients with LBP is minimal. The treatment of pediatrics with manual therapy, particularly spinal manipulation, is controversial within the medical community, primarily with r...
