  1. MOVEMENTS -Movement around a joint may be around any one (or more) of three axes -Most movements are found in pairs -For every movement, there is generally a movement that is opposite to it

  2. FLEXION-EXTENSION • Flexion – reduces the angle between two bones at a joint • Extension – increases the angle between two bones at a joint • Usually sagittal plane movement • E.g. Bicep Curl - Lifting the weight reduces the angle at the joint= flexion - Lowering the weight increases the angle at the joint = extension

  3. PRONATION-SUPINATION Movements relative to the forearm and hand PRONATION When the palm is moved to face posteriorly SUPINATION When the palm is moved to face anteriorly (hint: you can hold a bowl of soup)

  4. INVERSION- EVERSION Movements relative to the sole of the foot INVERSION when the sole is turned inward (as when you “go over ”on your ankle) EVERSION When the sole is turned outward or away from the median plane of the body

  5. DORSIFLEXIONPLANTAR FLEXION Modified flexion with respect to ankle joint DORSIFLEXION Bringing the top of the foot toward the lower leg or shin PLANTAR FLEXION -”planting” the foot

  6. ABDUCTION - ADDUCTION • ABDUCTION • Moving a segment away from the midline • Abduct = “take away” from the midline • Frontal plane movement • ADDUCTION • Moving segment towards the midline of the body • Adduct = “add” towards the midline • E.g. the motions of the arms and legs during a jumping jack

  7. CIRCUMDUCTION • CIRCUMDUCTION • A cone of movement that does not include any rotation • Occurs when flexion-extension movements are combined with abduction-adduction movements • E.g. tracing an imaginary circle in the air with your index finger

  8. ROTATION • Turning of a bone on its longitudinal axis • Medial rotation – rotation towards the midline • Lateral rotation – rotation away from the midline
