Partial Weight Bearing is a gait and activity restriction that limits how much body weight a person places through an injured or healing limb. It is a clinical **concept** and **rehabilitation instruction**, not a diagnosis or a specific procedure. It is commonly used after fractures, orthopedic surgery, and certain soft-tissue injuries. It is typically implemented and monitored by orthopedic teams and rehabilitation clinicians (physical therapy and occupational therapy).

Non Weight Bearing is a mobility restriction where a limb is kept from supporting body weight during standing or walking. It is a clinical concept and rehabilitation instruction used in orthopedics, trauma care, and postoperative management. It is commonly applied after fractures, tendon or ligament repairs, and certain joint surgeries. It is typically implemented using assistive devices such as crutches, walkers, or wheelchairs.

Weight Bearing describes how much body weight is permitted or tolerated through a limb or joint. It is a clinical concept used to guide safe movement after injury, surgery, or in painful musculoskeletal conditions. It is commonly referenced in orthopedic orders, physical therapy plans, gait training, and rehabilitation protocols. It is also used in imaging, where weight-bearing views can better show joint alignment and cartilage loss.

Ergonomics is the science of fitting work, tools, and environments to human capabilities. Ergonomics is a clinical and public-health concept rather than an anatomy structure or a single procedure. Ergonomics is commonly used in orthopedics, occupational medicine, rehabilitation, and workplace health. Ergonomics aims to reduce musculoskeletal stress while supporting safe, efficient function.

Posture Correction is a clinical concept focused on improving how the body is aligned and moves during sitting, standing, and activity. It is not one single treatment, but a framework that may include exercise, education, ergonomic changes, manual therapy, or bracing. It is commonly used in orthopedics, physical medicine and rehabilitation, physical therapy, and occupational health. It is discussed when alignment, muscle performance, and movement patterns are thought to influence symptoms or function.

Manual Therapy is a hands-on clinical approach used to assess and treat musculoskeletal pain and movement problems. It is best described as a **concept and set of procedures** performed by trained clinicians. It is commonly used in orthopedics, sports medicine, physical therapy, chiropractic, and osteopathic settings. It typically complements exercise-based rehabilitation and patient education.

Hydrotherapy is the therapeutic use of water to support rehabilitation, symptom control, and functional training. It is a clinical concept and treatment modality most commonly delivered as supervised aquatic therapy or water immersion techniques. In orthopedic and musculoskeletal practice, it is used in physical therapy settings, sports medicine, and postsurgical rehabilitation. It leverages water’s physical properties to modify loading, pain, and movement demands.

Occupational Therapy is a healthcare concept and clinical service focused on helping people participate in meaningful daily activities. It addresses function in self-care, work, school, and leisure by targeting physical, cognitive, sensory, and psychosocial factors. In musculoskeletal and orthopedic practice, it commonly supports recovery after injury or surgery and adapts tasks to current limitations. It is used across inpatient, outpatient, and community settings, often alongside other rehabilitation disciplines.

Physical Therapy is a healthcare approach focused on improving movement, function, and physical performance. Physical Therapy is a clinical concept and intervention delivered by licensed physical therapists and supported by rehabilitation teams. It is commonly used in orthopedics, sports medicine, neurology, cardiopulmonary care, and postoperative rehabilitation. In practice, it combines examination, exercise-based interventions, education, and functional training.

Rehabilitation is a structured process that helps a person restore function, reduce disability, and return to meaningful activities after injury, surgery, or illness. Rehabilitation is a clinical **concept** delivered through coordinated interventions (often physical therapy, occupational therapy, and related services). In musculoskeletal practice, Rehabilitation is commonly used after fractures, ligament or tendon injuries, joint replacement, spine conditions, and chronic pain syndromes. It is also used to optimize movement, strength, and participation before and after orthopedic procedures.
