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).
