Difference between Internal Rotation and External Rotation External rotation and internal rotation are terms used to describe movements that occur at joints, particularly in the context of the musculoskeletal system. External rotation refers to the movement of a body segment away from the midline of the body or the center of a joint. For example,…
What Is Distal Interphalangeal Joint Flexion and Extension? The distal interphalangeal joint (DIP) is the joint at the end of the finger or toe, near the nail. DIP flexion means to flex a finger or toe, bringing the tip of the finger to the palm or sole of the foot. The extension is a reverse…
What is Lumbar Flexion And Extension? Lumbar flexion and extension refer to the two main types of movement that occur in the lower part of the spine, specifically the lumbar region: Both lumbar flexion and extension are essential for the overall functionality of the spine. Maintaining a balance between these movements, along with stability and…
In physical therapy programs, the convex-concave rule is often discussed in the context of joint mobilizations or manipulations. The rule provides guidance on how the shapes of joint surfaces (convex or concave) affect the direction of movement during joint mobilization techniques. Here’s a brief explanation of the rule in the context of arthrokinematics and physical…
What is a Metacarpophalangeal Joint (MCP) Flexion & Extension? The Metacarpophalangeal (MCP) joint is a critical anatomical structure located in the hand, forming the connection between the metacarpal bones of the palm and the proximal phalanges of the fingers. These joints are essential for hand function and enable a wide range of movements that are…
What is Cervical rotation? Cervical rotation refers to the movement of the neck or cervical spine in which the head turns to either side. This move allows you to turn your head to look over your shoulder or change your field of vision without moving your entire body. The cervical spine consists of seven vertebrae…
What is Cervical Lateral Flexion? The cervical spine consists of seven vertebrae, and each vertebra is separated by intervertebral discs that allow flexibility and movement. Lateral flexion is one of the primary movements of the cervical spine, along with other movements such as flexion (bending forward), extension (bending back), and rotation (turning the head from…
What is Cervical Flexion And Extension? Cervical flexion and extension refer to the movements of the neck, specifically the forward and backward bending of the cervical spine (cervical vertebrae). Here’s a breakdown of each move: Cervical Flexion What is Cervical Flexion? Cervical flexion refers to the forward flexion or flexion movement of the neck. This…
What is Proximal Interphalangeal Joint Flexion And Extension? Proximal Interphalangeal (PIP) joint flexion and extension discuss the bending and straightening actions of the center joint of the fingers, that’s the PIP joint. The PIP joint is positioned among the proximal and center phalanges of the finger. Flexion of the PIP joint entails bending the finger…
What is an Ankle Inversion And Ankle Eversion? Ankle inversion and ankle eversion refer to movements that occur at the ankle joint. The ankle joint is formed by the tibia, fibula, and talus bones, and it allows for dorsiflexion (bringing the foot upward) and plantarflexion (pointing the foot downward). Ankle inversion is the movement of…
