Title: Understanding Synovial Joint Movements and Types
Movements at Synovial Joints
Notes on Definitions of Joint Movements
Term | Definition |
---|---|
Flexion | Decreasing the angle between two bones (bend). This movement is critical in many daily activities, such as bending the elbow to lift an object. |
Extension | Increasing an angle between two bones (straightening). Essential for movements like straightening the knee after a squat. |
Hyperextension | Extending beyond a straight line. Important in activities like backbends in yoga, but can be risky if done excessively. |
Dorsiflexion | Toes/foot point upwards. This is a crucial movement when walking or running to allow the foot to clear the ground. |
Plantarflexion | Toes/foot point downwards. Common in actions like standing on tiptoes or pushing off while running. |
Abduction | Pulling limbs away from the midline of the body. This movement is often observed in exercises like lateral raises. |
Adduction | Bringing limbs back to the midline. Important for movements such as bringing arms back to the sides after lateral raises. |
Circumduction | Circular motion at ball and socket joint, NOT twisting. This movement can be seen in shoulder rotations during activities like throwing. |
Rotation | 180-degree rotation (twist). This is common in sports and daily activities that require twisting the torso. |
Lateral rotation | Rotating out to the side. This movement assists in actions such as kicking a soccer ball. |
Medial rotation | Rotating in toward the midline. Important for movements like cross-body stretches. |
Supination | Palm rotates up. This position is essential for holding objects firmly in the hand. |
Pronation | Palm rotates down. Crucial for certain grips and movements in sports like tennis. |
Eversion | Elevating lateral soles (big toe). This movement is involved in stabilizing the foot during walking or running. |
Inversion | Elevating medial soles (pinky toe). This action helps maintain balance and control when navigating uneven surfaces. |
Protraction | To stick out. Commonly observed when pushing the shoulders forward, such as during a push-up. |
Retraction | To pull back in. This movement engages the muscles of the upper back, helping with posture and shoulder stability. |
Elevation | To raise up. Seen in movements like shrugging the shoulders or lifting arms overhead. |
Depression | To lower. This action is common in returning to a resting position after lifting. |
Additional Thoughts
Understanding these movements is essential for anyone involved in physical therapy, sports science, or fitness training, as they form the basis for assessing movement patterns, developing rehabilitation protocols, and enhancing athletic performance. Recognizing these movements can also help prevent injuries during physical activities.
