Blood flow restriction training is a rehabilitation and strength method that uses a specialized cuff or band around a limb during exercise. It partially limits blood flow out of the working muscles while allowing some blood flow in. It is commonly used in physical therapy, sports medicine, and orthopedic rehabilitation. It is often paired with low-load exercises when heavy lifting is not appropriate.

Single-leg hop test is a functional performance test that measures how well one leg can hop and land. It is commonly used to assess knee function after injury or surgery and during return-to-sport testing. It can also help describe side-to-side differences in strength, control, and confidence. Clinicians often use it in orthopedic, sports medicine, and physical therapy settings.

Functional testing is a set of standardized tasks that measure how well the knee works during real-life movements. It looks at strength, balance, control, and confidence during activities like squatting, stepping, or hopping. It is commonly used in orthopedics, sports medicine, and physical therapy to guide rehabilitation and activity decisions. It can complement imaging and a physical exam by showing what the joint can do, not just what it looks like.

Return to sport criteria are a set of clinical checks used to judge whether an athlete is ready to resume sport after injury or surgery. They combine physical exam findings, functional testing, and patient-reported measures into a structured decision. They are commonly used after knee injuries such as ACL tears, meniscus surgery, and patellar instability. They help align the athlete, therapist, and surgeon around a shared definition of “ready.”

Elliptical training is a form of aerobic exercise performed on an elliptical cross-trainer. The pedals move in an oval (“elliptical”) path, typically while the feet stay in contact with the platforms. It is commonly used in gyms, home fitness settings, and rehabilitation clinics. Many people use it as a lower-impact alternative to running for cardiovascular conditioning.

Cycling rehabilitation is the structured use of cycling to support recovery and function in the knee and other lower-limb joints. It commonly uses a stationary bike, recumbent bike, or controlled outdoor cycling. Clinicians often include it in physical therapy plans for pain, stiffness, weakness, or reduced endurance. It is typically paired with strength, mobility, and movement-training exercises.

Pool therapy is rehabilitation exercise performed in a pool, often called aquatic therapy or hydrotherapy. It uses water’s buoyancy and resistance to help people move with less joint loading. It is commonly used in physical therapy and sports medicine for knee pain, arthritis, and post-injury recovery. It may be delivered in hospitals, outpatient rehab clinics, or specialty aquatic centers.

Aquatic therapy is rehabilitation performed in a pool or water-based setting under clinical supervision. It uses water’s physical properties to support the body and change how joints and muscles are loaded. Aquatic therapy is commonly used in orthopedics, sports medicine, and physical therapy for pain and mobility problems. It is often part of a broader rehabilitation plan that may also include land-based exercise.

BMI reduction means lowering body mass index (BMI), a screening measure that relates weight to height. It is commonly discussed in joint health because body weight influences how much load the knee carries during daily activity. In orthopedic and sports medicine settings, BMI reduction is often part of a broader risk-reduction and function-improvement plan. It may be considered before or alongside physical therapy, injections, or surgery.

Weight loss counseling is a structured conversation and care process that helps a person reduce body weight in a safe, sustainable way. It usually includes goal-setting, nutrition guidance, physical activity planning, and behavior-change strategies. It is commonly used in primary care, orthopedics, sports medicine, physical therapy, and chronic disease clinics. In knee care, it is often discussed when extra body weight is contributing to pain, limited mobility, or arthritis symptoms.
