Movements at a joint

The human body exhibits various joint movements facilitated by the skeleton and muscles, including flexion, extension, rotation, abduction, adduction, dorsiflexion, and plantarflexion. These movements are made possible by different types of joints, primarily ball-and-socket and hinge joints. Flexion and extension involve bending and straightening joints, respectively. Rotation occurs at ball-and-socket and pivot joints, while abduction and adduction refer to movements away from and towards the body's center. Awareness of these movements can aid in preventing injuries through proper techniques and recovery methods such as RICE.

  1. Movements at a joint

  2. Types of Movement There are many types of movement that the skeleton and muscles can produce. The following are the most common: • Flexion • Extension • Rotation • Abduction • Adduction • Dorsiflexion- Flexing • Plantarflexion- Pointing

  3. Types of Movement cont’d FLEXION – Bending the joint. E.g. Bending the knee or elbow. BALL and SOCKET and HINGE are the main joint types that can produce this movement.

  4. Types of Movement cont’d EXTENSION of a joint is where the joint is straightened. BALL and SOCKET and HINGE joints are common examples of joints that can produce this movement. Straightening the leg when striking a ball is an example of EXTENSION at the knee (HINGE JOINT)

  5. Types of Movement cont’d The ROTATION movement can occur at a BALL and SOCKET and a PIVOT joint. e.g. turning the head or the movement at the shoulder when swimming backstroke. In Dance this could be a windmill arm or leg

  6. Types of Movement cont’d ABDUCTION and ADDUCTION movements can be produced by BALL and SOCKET joints. ABDUCTION is where a limb moves away from the centre of the body. ADDUCTION is where the limb is moved TOWARDS the centre of the body.

  7. Joints and Performance Injuries to joints can occur from: • Over use (Too much training) • Incorrect movement injuries (e.g.-wrong techniques) • Impact or twisting (e.g.-twist of knee or elbow) Such injuries should be RICED: given plenty rest, iced, compressed, elevated and diagnosed (if serious) to aid recovery and avoid permanent damage.
