Kinesiology Laboratory 4:Activity Analysis of the Upper Extremity
Today’s ActivitiesSoft Tissue Palpation of the Wrist and HandActivity Analysis
Military PressSit Up
Soft Tissue PalpationUnderstanding 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 HandExtensor Pollicis BrevisExtensor Pollicis LongusExtensor Digitorum CommunisExtensor Indicis PropriusExtensor Digiti MinimiExtensor 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 UlnarisAction: Extends and adducts (ulnarly
deviates) the wristLocation: On ulnar side of pinky. Less
prominent/superficial than the EDM/EDQ.

Palmaris LongusAction: 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 EminenceLocation: Muscle pad along the thumb
side of hand (made up of 3 muscles: Abductor pollicis brevis, Flexor pollicis brevis and Opponens pollicis).
Hypothenar EminenceLocation: Muscle pad along the pink side
of hand (made up of 3 muscles: Opponens digiti minimi, Flexor digiti minimi & Abductor digiti minimi).
