Gait analysis, joint mechanics, physical therapy, and motor control
Rehabilitation and movement simulations model the biomechanics and motor control underlying human locomotion and therapeutic exercise. Gait-analysis simulations animate joint angles, ground-reaction forces, and muscle-activation envelopes through a complete walking stride, comparing normal gait kinematics to pathological patterns (drop foot, antalgic gait, Trendelenburg sign). Inverse-dynamics solvers compute joint moments and powers from marker trajectories — the same output produced by clinical motion-capture systems.
Balance and postural-control simulations model the inverted-pendulum dynamics of standing and the sensory-integration weighting (visual, vestibular, proprioceptive) used in Romberg and sensory-organisation tests. Exercise-prescription models compute therapeutic dose–response relationships for range-of-motion, strength, and cardiovascular conditioning protocols. These simulations are used in physiotherapy education, prosthetics and orthotics engineering, and sports-medicine research.
Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.

Common questions about this simulation category
Every Rehabilitation simulation here runs free in your browser, letting you experiment with each interactive Rehabilitation model — physical therapy exercise progressions, recovery timelines and mobility restoration protocols — without installing anything. Adjust parameters, observe real-time results and learn Rehabilitation science online at your own pace, whether you are a student, healthcare educator or curious researcher. Rehabilitation medicine focuses on restoring physical function, reducing pain and improving quality of life following injury, surgery or illness, drawing on biomechanics, neuroscience and exercise physiology to design evidence-based recovery programmes. These simulations illustrate how variables such as exercise intensity, frequency and patient adherence interact to influence recovery speed and long-term functional outcomes.
