Terminology O Muscle strength- the ability to generate force. Measured with a 1 repetition maximum (1RM). O Muscle endurance – the ability to repeatedly contract a muscle without fatigue. Measured with a sit-up test – number of sit-ups in 1 minute. O Proprioception - The ability to sense stimuli arising within the body regarding position, motion, and equilibrium. In other words, the ability of the body to sense positioning of trunk, limbs, etc. 6/23/2016 Property of CTE Joint Venture4

Terminology O PRE (progressive resistive exercise)- exercises that become increasingly more difficult O RROM (resistive range of motion)- some form of resistance is applied to the movement O Manual resistance- clinician physically resists range of motion 6/23/2016 Property of AZ CTE Curriculum Consortium5

Terminology O Isometric – constant length. Contracting the muscle without any joint movement 6/23/2016 Property of CTE Joint Venture6

Terminology O Isotonic – constant weight. Contracting the muscle and lifting a weight 6/23/2016 Property of CTE Joint Venture7

Terminology O Isokinetic – constant speed. Contracting the muscle while moving the resistance arm of a machine 6/23/2016 Property of CTE Joint Venture8

Terminology O SLR (straight leg raise)- ROM performed at hip if there is a lower extremity injury that prevents knee ROM O Open kinetic chain exercises- when the foot or hand is mobile or off the ground O Closed kinetic chain exercises- when the foot or hand is fixed or on the ground O Neuromuscular control- ability for muscles to respond to environmental changes 6/23/2016 Property of CTE Joint Venture9

Considerations 6/23/2016 Property of AZ CTE Curriculum Consortium10 O Protect healing tissue, but must provide some stress for proper healing (Wolff’s law) O PRE O Safe ROMs and planes of movement O Exercise choice O Maintain rest of body fitness to prevent atrophy

Strengthening O Isometric vs. isotonic vs. isokinetic O Easy progression: O Isometric O Gravity resistance O Light weight or manual resistance O Tubing/bands 6/23/2016 Property of CTE Joint Venture11

Using tubing or bands for strengthening is an isotonic exercise? True/False ? 12

Endurance O Pain-free ROM O No undue stress to healing site O Examples: O Bike O UBE- upper body ergometer O Rowing O Swimming O Elliptical O Treadmill 6/23/2016 Property of CTE Joint Venture13 hand-on-a-ube/

Is the UBE an open-kinetic chain endurance exercise? True/False ? 14

Proprioception O Static balance exercises- tandem stance or one leg O Flat hard surface O Foam or mat surface O Add weights or movements to each O Static upper extremity exercises O Mirror movements between limbs O Closed kinetic chain stability on hand- tandem and single arm 6/23/2016 Property of CTE Joint Venture15 -home-knee-strengthening-exercises/

Is this an open-kinetic chain proprioceptive exercise for the shoulder? True/False ? 16

Closure 6/23/2016 Property of AZ CTE Curriculum Consortium17 Summarize today’s lesson on your Exit Ticket. What did you learn about progression? What is an example of a strengthening exercise? A proprioceptive exercise?
