1 Kinesiology Laboratory 4: Activity Analysis of the Upper Extremity
2 Today’s Activities Soft Tissue Palpation of the Wrist and Hand Activity AnalysisMilitary PressSit Up
3 Soft Tissue PalpationUnderstanding the anatomy of the tendons can lead to greater understanding of injuries that can occurTendon injuries in the hand are very common and lead to a decreased quality of lifeUnderstanding the location of the tendons and applying them to the principles of active and passive insufficiency observed in Lab 2
6 Extensor Tendons of the Hand Extensor Pollicis BrevisExtensor Pollicis LongusExtensor Digitorum CommunisExtensor Indicis PropriusExtensor Digiti MinimiExtensor Carpi Ulnaris
7 Extensor Pollicis Brevis (EPB)/ Extensor Pollicis Longus (EPL) Action: Work together to extend and abduct the thumb at the Wrist and MCP jointLocation: Make up ulnar (EPL) and radial (EPB) sides of anatomical snuffbox.
8 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
9 Extensor Indicis Proprius (EIP) Action: Extends the MCP joint and extends the PIP & DIP joints of the index fingerLocation: Ulnar side of index finger, along EDC. It is less superficial than the EDC
10 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
11 Extensor Carpi Ulnaris Action: Extends and adducts (ulnarly deviates) the wristLocation: On ulnar side of pinky. Less prominent/superficial than the EDM/EDQ.
12 Flexor Tendons and Muscles of the Hand Palmaris LongusFlexor Carpi RadialisThenar EminenceHypothenar EminenceMCP Ligaments
13 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.
14 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.
15 Thenar EminenceLocation: Muscle pad along the thumb side of hand (made up of 3 muscles: Abductor pollicis brevis, Flexor pollicis brevis and Opponens pollicis).
16 Hypothenar EminenceLocation: Muscle pad along the pink side of hand (made up of 3 muscles: Opponens digiti minimi, Flexor digiti minimi & Abductor digiti minimi).
