Comprehensive Analysis of Upper Extremity Kinesiology and Soft Tissue Palpation Techniques

This laboratory activity focuses on the intricate analysis of the upper extremity, emphasizing soft tissue palpation of the wrist and hand. Key components include an exploration of tendon anatomy, understanding common tendon injuries, and their impact on quality of life. Students will learn about various extensor and flexor tendons, their actions, and palpation techniques. Additionally, the analysis of movements, including military press and sit-ups, will be conducted, involving muscle functional groups, contraction types, and biomechanical principles.

Presentation Transcript

  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

  4. Extensor Tendons of the Hand • Extensor Pollicis Brevis • Extensor Pollicis Longus • Extensor Digitorum Communis • Extensor Indicis Proprius • Extensor Digiti Minimi • Extensor Carpi Ulnaris

  5. Extensor PollicisBrevis (EPB)/Extensor PollicisLongus (EPL) • Action: Work together to extend and abduct the thumbat the Wrist and MCP joint • Location: Make up ulnar (EPL) and radial (EPB) sides of anatomical snuffbox.

  6. Extensor DigitorumCommunis (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

  7. 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

  8. Extensor DigitiQuinti (EDQ) or Extensor DigitiMinimi (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

  9. Extensor Carpi Ulnaris • Action: Extends and adducts (ulnarly deviates) the wrist • Location: On ulnar side of pinky. Less prominent/superficial than the EDM/EDQ.

  10. Flexor Tendons and Muscles of the Hand • Palmaris Longus • Flexor Carpi Radialis • Thenar Eminence • Hypothenar Eminence • MCP Ligaments

  11. 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 palmarislongus protrude proximally-distally along the wrist.

  12. 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.

  13. 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).

  14. 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).

  15. 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!

  16. In Two Weeks • Lab Report 4 • Midterm Practicals • Activity Analysis • Push up • Sit up • Military Press • Bench Press • Palpations (Labs 1 and 4)
