Short paths into the atlas — pick one and follow the seven sections.

🦵KneeThe knee is the body's largest joint and one of its most frequently injured, relying on ligaments and surrounding muscles rather than bony shape for stability.🔙Lower BackThe lumbar spine bears more compressive load than any other spinal region, making low back pain the single most common musculoskeletal complaint worldwide.🏋️ShoulderThe shoulder trades stability for the greatest range of motion of any joint in the body, relying heavily on the rotator cuff muscles rather than bone to stay centered.⚖️BalanceBalance depends on the brain continuously combining signals from the inner ear, eyes, and joints, and its decline is one of the strongest predictable predictors of falls in older adults.

NeckThe seven cervical vertebrae and the soft tissues that carry the head — posture load, disc and facet pain, and graded mobility work.Lower BackThe lumbar spine bears more compressive load than any other spinal region, making low back pain the single most common musculoskeletal complaint worldwide.CoreThe core is the coordinated group of trunk muscles that stabilizes the spine and pelvis, transferring force between the upper and lower body during nearly every movement.ShoulderThe shoulder trades stability for the greatest range of motion of any joint in the body, relying heavily on the rotator cuff muscles rather than bone to stay centered.ElbowThe elbow's hinge-and-rotation design lets the forearm bend and turn simultaneously, but this dual role concentrates repetitive stress on a small set of tendons.Wrist & HandThe wrist and hand pack more small joints, tendons, and nerves into a small space than almost any other body region, enabling fine motor control at the cost of frequent overuse injury.

Browse every topic

Hip

The hip is a deep, stable ball-and-socket joint that bears several times body weight during walking and running, making it a common site of both overuse pain and degenerative change.

Pain frequency 55

Knee

The knee is the body's largest joint and one of its most frequently injured, relying on ligaments and surrounding muscles rather than bony shape for stability.

Pain frequency 65

ACL

The anterior cruciate ligament stabilizes the knee against pivoting and forward-sliding forces, and its rupture is one of the most studied and rehabilitation-intensive sports injuries.

Pain frequency 50

Ankle & Foot

The ankle and foot absorb and redirect the full force of body weight with every step, making sprains and overuse injuries among the most common in sport and daily life.

Pain frequency 70
