Movement Retraining Can Reduce Knee Pain

The video explores knee pain, particularly osteoarthritis, and how changing one's gait can alleviate it. Supported by the National Science Foundation, researchers at Stanford University use sensors and software to analyze joint forces and suggest gait modifications. These changes aim to reduce stress on the knee joint, potentially easing pain. The team also develops biofeedback devices to help subjects learn new gaits, with applications extending to athletes. The research highlights the potential of stride therapy in improving health and performance.

What percentage of older adults show signs of knee osteoarthritis?

• 50%

• 25%

• 75%

• 100%

What is the primary goal of Mark Kokosky's research team?

• To invent a new pain medication

• To develop new knee replacement techniques

• To create a new type of treadmill

• To help people live healthier lives by changing their stride

How does the research team determine if a gait change might alleviate pain?

• By testing different types of shoes

• By observing participants' walking habits

• By conducting surveys with participants

• By using a biomechanics model and analyzing joint forces

What is one of the major problems leading to knee pain?

• Genetic factors

• Lack of exercise

• Uneven wear and tear on the cartilage

• Poor diet

What is the purpose of the biofeedback device developed by the research team?

• To track daily step count

• To reinforce modified gait patterns outside the lab

• To monitor heart rate during exercise

• To measure blood pressure
