1. Kinesiology Laboratory 4:
Activity Analysis of the Upper Extremity

2. Today’s Activities Soft Tissue Palpation of the Wrist and Hand
Activity Analysis
Military Press
Sit Up

3. 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

6. Extensor Tendons of the Hand
Extensor Pollicis Brevis
Extensor Pollicis Longus
Extensor Digitorum Communis
Extensor Indicis Proprius
Extensor Digiti Minimi
Extensor 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 joint
Location: 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 finger
Location: 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 wrist
Location: On ulnar side of pinky. Less prominent/superficial than the EDM/EDQ.

12. Flexor Tendons and Muscles of the Hand
Palmaris Longus
Flexor Carpi Radialis
Thenar Eminence
Hypothenar Eminence
MCP 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 Eminence
Location: Muscle pad along the thumb side of hand (made up of 3 muscles: Abductor pollicis brevis, Flexor pollicis brevis and Opponens pollicis).

16. 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).

17. Activity Analysis: Military Press/Sit Up
Chart breaking down the movement by joint FOR BOTH PHASES
Osteokinematic motion (Flex, adduct, etc.)
Muscle Functional Group (i.e. Wrist Flexors)
Agonist & Synergists
Contraction Type
Planes and axes
Effects of gravity (Resisting, Assisting, No effect)
Narration of chart
Diagram of movement (up phase/down phase)
Use arrows for gravities effect
Diagram of a single joint
Identify muscle group and Contraction Type
Identify the type of lever
Label the Axis, Effort and Resistance
PAY ATTENTION TO LAB HANDOUT!
