1Kinesiology Laboratory 4: Activity Analysis of the Upper Extremity
2Today’s Activities Soft Tissue Palpation of the Wrist and Hand Activity AnalysisMilitary PressSit Up
3Soft 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
6Extensor Tendons of the Hand Extensor Pollicis BrevisExtensor Pollicis LongusExtensor Digitorum CommunisExtensor Indicis PropriusExtensor Digiti MinimiExtensor Carpi Ulnaris
7Extensor 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.
8Extensor 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
9Extensor 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
10Extensor 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
11Extensor Carpi Ulnaris Action: Extends and adducts (ulnarly deviates) the wristLocation: On ulnar side of pinky. Less prominent/superficial than the EDM/EDQ.
12Flexor Tendons and Muscles of the Hand Palmaris LongusFlexor Carpi RadialisThenar EminenceHypothenar EminenceMCP Ligaments
13Palmaris 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.
14Flexor 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.
15Thenar EminenceLocation: Muscle pad along the thumb side of hand (made up of 3 muscles: Abductor pollicis brevis, Flexor pollicis brevis and Opponens pollicis).
16Hypothenar EminenceLocation: Muscle pad along the pink side of hand (made up of 3 muscles: Opponens digiti minimi, Flexor digiti minimi & Abductor digiti minimi).
