Concentric Finger Flexion Against Resistance

In this video, the motion of finger flexion is occurring at the metacarpophalangeal (MCP) and interphalangeal (IP) joints while squeezing the ball. This motion is controlled by concentric muscle contraction against the resistance from the ball. Concentric metacarpophalangeal (MCP) and interphalangeal (IP) joint flexion is demonstrated from a position of 90⁰ of elbow flexion as seen from a front or anterior view.

Eccentric Finger Extension With Resistance

In this video, the motion of finger extension is occurring at the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This motion is controlled by eccentric muscle contraction against the resistance from an elastic band. Eccentric metacarpophalangeal and interphalangeal joint extension is demonstrated from a fully flexed hand position as seen from a front or anterior view.

Finger Flexion

In this video, the motion of finger flexion is occurring at the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This motion is controlled by concentric muscle contraction. Concentric metacarpophalangeal (MCP) and interphalangeal (IP) joint flexion is demonstrated starting with the arm at the side of the body and the palm facing forward in the anatomical position for the upper extremity and ending in a fully flexed position as seen from a side or lateral view.

Finger Intrinsic Plus

In this video, the motion of the fingers beings at the extrinsic plus position with metacarpophalangeal (MCP) joint extension and interphalangeal (IP) joint flexion. The motion ends in the intrinsic plus position with metacarpophalangeal (MCP) joint flexion and interphalangeal (IP) joint extension as seen from a side or lateral view.

Finger Adduction

In this video, the motion of bringing the fingers together is adduction. Adduction is occurring at the metacarpophalangeal joints. Metacarpophalangeal adduction is demonstrated from a position of the fingers being spread apart to a position of full adduction as seen from a front or anterior view.

Finger Abduction

In this video, the motion of spreading apart the fingers is abduction. Abduction is occurring at the metacarpophalangeal joints. Metacarpophalangeal abduction is demonstrated from a position of the fingers being close together to a position of full abduction as seen from a front or anterior view.

Finger Extension

In this video, the motion of finger extension is occurring at the metacarpophalangeal and interphalangeal joints. This motion is controlled by eccentric muscle contraction. Eccentric metacarpophalangeal and interphalangeal joint extension is demonstrated from a fully flexed hand position as seen from a side or lateral view.

Thumb Flexion

In this video, the motion of bringing the thumb across the palm is flexion. The motion of flexion is occurring at the 1st carpometacarpal (CMC) joint of the thumb. 1st CMC flexion is demonstrated from a position with the thumb in a neutral resting location to a position with the thumb moving as far across the palm as possible as seen from a side or lateral view.

Thumb Abduction

In this video, the motion of bringing the thumb away from the palm is abduction. The motion of abduction is occurring at the 1st carpometacarpal (CMC) joint of the thumb. 1st CMC abduction is demonstrated from a position with the thumb resting on the palm to a position of the thumb moving as far away from the palm as possible as seen from a front or anterior view.

Wrist Flexion With Resistance

In this video, the action of flexing the wrist with resistance is a concentric muscle contraction. Concentric wrist flexion is demonstrated from a neutral wrist position to a fully flexed wrist position as seen from a front or anterior view.

Wrist Extension from Flexion

In this video, the action of controlling the extension of the wrist from a fully flexed position is an eccentric muscle contraction. The motion occurring at the wrist is eccentric wrist extension. Eccentric wrist extension is demonstrated from a side or lateral view.
