Which of the following are characteristics of isokinetic exercises?
Fixed Speed with Variable Resistance
Machine accommodates itself to the user throughout the ROM
The machine will only move at a given speed; and it maintains the speed by adjusting the resistance relative to the force being received.
Load is dependent on the velocity of limb movement throughout the arc of motion.
By controlling the speed of the exercise, maximum resistance throughout the full ROM is developed and all points of range can be worked maximally.
Can accommodate muscle fatigue as well as painful arc.
Muscles can be worked in both concentric and eccentric contractions.
Good choice for strengthening when a person has pain with joint movement, but still needs to gain or at least maintain muscle strength
Good choice for gentle muscle pumping soon after surgery
Combination of an eccentric load followed by a fast concentric contraction
At which stage of condition should you consider starting a patient on isokinetic exercises?
Acute
Early Sub-Acute
Late Sub-Acute
Settled
Chronic
When starting a patient on Isokinetic exercises, you should start with slow speed exercises (30-60 degrees per second) and then progress to faster speeds (120-180 degrees per second).
Your patient is doing well with their isokinetic exercises and you feel they are ready to progress. Which of the following are appropriate for training muscular endurance with an isokinetic machine?
Increase Repetitions
Reduce the speed of the machine
Decrease Repetitions
Increase the speed of the machine
Increase the resistance
Which of the following might indicate that your patient is reaching fatigue during an exercise?
Tremors during muscular contraction
Declining ROM over the course of a set
Increasing involvement of compensatory muscles
Increasing ROM over the course of a set
Decreasing involvement of compensatory muscles
In what order are muscle fibers recruited during a high-demand contraction? 1. ❌ 2. ❌ 3. ❌
For the past 2 weeks you have been helping a patient increase his quadriceps strength (among other things). Following POP, you've been adding resistance each workout. Which of the following mechanisms are contributing to these strength gains?
Muscle Fiber Transformation (Slow Twitch -> Fast Twitch)
Better oxidative capacity (mitochondrial adaptations)
Hypertrophy of the muscle fibers
Increased recruitment of motor units (neurological adaptations)
Hyperplasia of the muscle fibers
Due to OA-related pain, your patient cannot exercise through the full-range of elbow flexion. Which type of strengthening exercise would you recommend?
Isotonic
Isokinetic
Isometric
Plyometric
Plyometrics is the combination of a concentric load followed by a fast eccentric contraction.
A plyometric activity is a quick, powerful movement involving pre-stretch of the muscle (eccentric), and activates the “stretch-shortening cycle” to produce a stronger concentric contraction.
Which of the following types of exercise does Dr. Pong describe as a bunny hoping quickly across the yard?
The amortization phase takes advantage of the Stretch Shorten Cycle, thus you should encourage your patient to pause for a 2-count during the amortization phase.
If my patient is doing a plyometric chain exercise using a weighted object, the best way to progress the exercise is to _____.
shorten the amortization phase
increase the weight of the object
do it backwards.
close your eyes.
Which of the following types of exercises would be the best choice for increasing the tensile strength of a ligament?
What is the order of progression for heel raises? 1.) ❌ 2.) ❌ 3.) ❌
Match the location with the nerve that runs near it. Lateral Proximal Tibia :: ❌ Medial Knee :: ❌ Volar Wrist :: ❌ Medial Elbow :: ❌ Mid-Piriformis :: ❌
Improper form while using the Leg Press machine can cause which of the following conditions?
Herniated Nucleus Pulposus in the Lumbar Spine
Cervical Stenosis
Lumbar Stenosis
Scoliosis
Which is the correct equation for the Noyes Hop Test?
(o1+o2)/(g1+g2)x100 = Score
(o1+g1)/(o2+g2)x100 = Score
(o1+o2)x(g1+g2)x100 = Score
(o1+g1)x(o2+g2)x100 = Score
(g1+g2)/(o1+o2)x100 = Score
What is the magic number for the Noyes Hop Test?
80%
85%
90%
95%
If a patient scores an 80% on the Noyes Hop Test, which of the following are true?
Patient is ready to return to school basketball
Patient is ready to advance to Plyometrics
Patient should work on Eccentrics
Joint is too unstable to tolerate any form of exercise
You are performing a gait assessment and have determined that your patient ambulates with a foot slap, due to muscle weakness. Which of the following would be an appropriate exercise to correct this?
Eccentrics for the Ankle Dorsiflexors
Concentrics for the Ankle Plantarflexors
Eccentrics for the Ankle Plantarflexors
Concentrics for the Ankle Dorsiflexors
During a gait assessment, you notice that your patient has a deficit in knee and hip flexion during swing phase. What could cause this?
Weak Hamstrings
Tight Quadriceps
Scar Tissue in the knee joint
You administer the Deep Squat Test to your patient. The patient is unable to achieve a perfect score. What joint range of motion limitations could be causing this?
Ankle DF
Knee Flexion
Hip Flexion
Ankle PF
Knee Extension
Hip Extension
When you are administering the Hurdle Step Test, what will you be able to assess in your patient?
the patient’s proper stride mechanics during a stepping motion
the patient’s coordination and stability between the hips and torso that is needed during single leg stance
the patient’s bilateral functional mobility and stability of the hips, knees, and ankles
the length of the patient's tibia
the patient's ability to progress to plyometrics
Why is the Functional Movement Screen (FMS) used?
To teach PTs how to restore and improve functional movement patterns in asymptomatic individuals
To identify individuals who have developed compensatory movement patterns in the kinetic chain.
To portray movement-pattern quality with a simple grading system
To determine why a dysfunctional or faulty movement pattern exists
To measure isolated joint movement and diagnose any deficiencies
