strength in rehabilitation Flashcards
goal of active rom
Maintain/increase ROM, improve movement patterns, and help reduce atrophy
how does the muscle move in gravity assisted movement
Muscle in question is moving perpendicular to the floor in downward motion
how does the muscle move in gravity assisted movement
Muscle in question is parallel to the floor, perpendicular to gravity
why use isometric exercise
- Minimize muscle atrophy when joint movement is not possible
- Activate muscles to begin to re-establish neuromuscular control
* Protect healing tissues - Develop postural and joint stability
- Improve muscular strength when dynamic RT could compromise joint integrity or cause pain
- Develop static muscular strength at particular points of ROM (20° max) * Specific task related needs
when does isometric contraction is uses
in acute stage of healing
what does isometric contraction promote
relaxation and circulation after injury
what is the muscle setting for isometric contraction
low intensity isometric contractions performed against little or no resistance
why do we use stabilization exercise
improve postural stability or dynamic stability of a join
what is rhythmic stabilization
Applied resistance in multiple directions to facilitate sequential muscle activation
what is multi-angle isometric
Manual or mechanical resistance is applied at multiple joint positions within available ROM
goal of multi-angle isometric
improve strength through rom
when do we use multi angle isometric
when dynamic resistance exercise is painful or inadvisable
how many % of a muscle voluntry contraction do we need to improve strength
66-100%
how many sec do we hold the position in isometric contraction
10 sec (2sec rise, 6 sec hold, 2 sec release)
benefit of repetitive contraction
- Decrease muscle cramping
- Increases effectiveness of isometric goals
how does the resistance must be apply
- Resistance must be progressively increased to overload the muscle *
Apply and release the tension gradually
concentric vs eccentric contraction
conc: shortening of a muscle with contraction, accelerate body segment
ecc: lengthening of a muscle while controlling against force, decelerate body segment, shock absorber
what is isotonic activity
- Involves change in muscle length
- Constant resistance throughout
the exercises - Speed of movement will change
what is isokinetic activity
Involves change in muscle length
* Velocity is controlled and maintained at a specific speed of movement
* “Having the same motion”
* Amount of resistance provided to the muscle varies as the muscle goes through a range
* Form of dynamic exercise in which velocity of a muscle shortening or
lengthening and the angular limb is predetermined
which one between isokinetic and isotonic that Movement that occurs at an equal or constant velocity (speed)
isokinetic
where does isokinetic exercise is used
rehab setting
what are the characteristic of isokinetic exercise
train reciprocal muscle
compressive force on join is less with faster velocties than at slow velocities
patient can still perform exercise even if fatigued
patient is able to eliminate painful ac
speed avaible in sport is more than in machine
which type of exercise can train reciprocal muscles
isokinetic
type of resistance exercise depend on
- Extent of impairments
- Stage of tissue healing
- Condition of joints and their tolerance to compression and movement
- General physical and cognitive abilities of the patient
- Patient’s goals
