Activity Analysis of the Upper Extremity
Today’s Activities Soft Tissue Palpation of the Wrist and Hand Activity Analysis Military Press Sit Up
Soft Tissue Palpation Understanding the anatomy of the tendons can lead to greater understanding of injuries that can occur Tendon injuries in the hand are very common and lead to a decreased quality of life Understanding the location of the tendons and applying them to the principles of active and passive insufficiency observed in Lab 2
Extensor Tendons of the Hand Extensor Pollicis Brevis Extensor Pollicis Longus Extensor Digitorum Communis Extensor Indicis Proprius Extensor Digiti Minimi Extensor Carpi Ulnaris
Extensor Pollicis Brevis (EPB)/ Extensor Pollicis Longus (EPL) Action: Work together to extend and abduct the thumb at the Wrist and MCP joint Location: Make up ulnar (EPL) and radial (EPB) sides of anatomical snuffbox.
Extensor Digitorum Communis (EDC) Action: Extension of the hand, wrist and all phalanges. Location: Tendon branches from the wrist, along the phalanges on the dorsal surface. The pinky and ring finger share a tendon. Palpation trick: Making a clawed grasp
Extensor Indicis Proprius (EIP) Action: Extends the MCP joint and extends the PIP & DIP joints of the index finger Location: Ulnar side of index finger, along EDC. It is less superficial than the EDC
Extensor Digiti Quinti (EDQ) or Extensor Digiti Minimi (EDM) Action: Extend the MCP and extends the PIP and DIP of the little finger. Location: Located on radial side of pinky. Most prominent tendon on extensor side of pinky
Extensor Carpi Ulnaris Action: Extends and adducts (ulnarly deviates) the wrist Location: On ulnar side of pinky. Less prominent/superficial than the EDM/EDQ.
Flexor Tendons and Muscles of the Hand Palmaris Longus Flexor Carpi Radialis Thenar Eminence Hypothenar Eminence MCP Ligaments
Palmaris Longus Action: Flexes the wrist, may assist in elbow flexion. Location: On palmar surface of wrist. Most superficial tendon. Palpation trick: Holding a round object in hand, flex the wrist to see the palmaris longus protrude proximally- distally along the wrist.
Flexor Carpi Radialis (FCR) Action: Flexes and abducts (radially deviates) the wrist, may assist in pronation of the forearm and flexion of the wrist. Location: Deep to the Palmaris Longus, it runs proximally-distally along the wrist. Located on the radial side of wrist.
Thenar Eminence Location: Muscle pad along the thumb side of hand (made up of 3 muscles: Abductor pollicis brevis, Flexor pollicis brevis and Opponens pollicis).
Hypothenar Eminence Location: Muscle pad along the pink side of hand (made up of 3 muscles: Opponens digiti minimi, Flexor digiti minimi & Abductor digiti minimi).
