Strength in rehab

Question 1

AAROM

Answer 1

desirable for patient to perform limited voluntary activity

Question 2

AROM

Answer 2

produce full ROM without assistance
maintain/increase ROM, improve movement patterns, help reduce atrophy

Question 3

RROM

Answer 3

motion with resistance applied

Question 4

Anti-gravity movement

Answer 4

body part is lifted against the force of gravity
type of resistance exercise

Question 5

gravity assisted movement

Answer 5

movement where body part is helped by gravity
less work required by muscle
muscle is moving perpendicular to the floor in downward motion

Question 6

gravity eliminated movement

Answer 6

muscle is parallel to the floor, perpendicular to gravity

Question 7

isometric contraction

Answer 7

muscle is not moving through a ROM

Question 8

concentric contraction

Answer 8

going through a shortening motion, produces force

Question 9

eccentric contraction

Answer 9

lengthening motion, controls force, slows you down

Question 10

what happens if strength, power or endurance are impaired

Answer 10

person will have active limitation or increased risk of injury

Question 11

what needs to be done in a rehab setting

Answer 11

thorough evaluation of the patient
qualitative and quantitative baselines of strength, ROM, overall level of functioning
where in the program will strengthening be implemented with other therapeutic interventions

Question 12

why do we use isometric exercises

Answer 12

1. minimize muscle atrophy when joint mvt is not possible
2. activate muscle to begin re-establish neuromuscular control
3. develop postural and joint stability
4. improve muscular strength when dynamic RT could compromise joint integrity or cause pain
5. develop static muscular strength at particular ROM

Question 13

what is the muscle setting with isometric exercises

Answer 13

low intensity isometric contractions performed against little to no resistance
used to decrease muscle pain ant spasm
promote relaxation and circulation after injury
used in acute stages of healing

Question 14

what is a form of isometric exercise

Answer 14

stabilization exercise

Question 15

what are stabilization exercises used for

Answer 15

improve postural stability or dynamic stability of a joint

Question 16

what are rhythmic stabilizations and alternating isometrics

Answer 16

applied resistance in multiple directions to facilitate sequential muscle activation

Question 17

what are multi-angle isometrics

Answer 17

manual or mechanical resistance is applied at multiple joint positions within available ROM

Question 18

what is the goal of multi-angle isometrics

Answer 18

improve strength through ROM

Question 19

when do we use multi-angle isometrics

Answer 19

when dynamic resistance exercise is painful or inadvisable

Question 20

what % of muscle voluntary contraction is sufficient to improve strength

Answer 20

66-100%
33-66 there are some gains but improvement is slow

Question 21

10 sec hold (isometric)

Answer 21

2 sec rise, 6 sec hold, 2 sec release

Question 22

what happens with repetitive isometric contractions

Answer 22

decrease m. cramping
increase effectiveness of isometric goals

Question 23

what happens to resistance in isometric contractions

Answer 23

resistance must be progressively increased to overload the muscle

Question 24

what is included is dynamic activity

Answer 24

isotonic
isokinetic

Question 25

isotonic activity

Answer 25

change in muscle length
constant resistance throughout the exercises
speed of the movement will change

Question 26

isokinetic activity

Answer 26

changes in muscle length
velocity is controlled and maintained at a specific speed of movement
amount of resistance provided to the muscle varies as the muscle goes through a range

Question 27

what are the characteristics of isokinetic exercise

Answer 27

can train reciprocal muscles
compressive forces on the joint are less with faster velocities than at slow velocities
patient can still perform exercise even if fatigued
patient is able to eliminate painful arc

Question 28

what is a disadvantage to isokinetic exercises

Answer 28

isolates movement and m. , not sport sepcific

Question 29

what do the type of resistance exercise depend on

Answer 29

extent of impairments
stages of tissue healing
condition of joints and their tolerance to compression and movement
general physical and cognitive abilities of the patient
patient’s goals

Question 30

do we need open kinetic chain and closed to correct movement patterns

Answer 30

yes

Question 31

when to use OKC

Answer 31

when weight bearing is contraindicated
soft tissue pain and swelling or restricted ROM
develop isolated control and strength of weak m.
sport/activity requires it

Question 32

when to use CKC

Answer 32

promote dynamic stabilization and co-activation
provides greater proprioceptive and kinesthetic feedback
provides more joint stability
sport/activity requires it

Question 33

when are rapid gains is strength seen

Answer 33

in the first 3-5 weeks with a debilitated/deconditioned muscle

Question 34

how are goals for rehab set

Answer 34

depends on the patients long term goals and demands

Question 35

what % of strength is required to RTP in clinic

Answer 35

90%

Question 36

what is the common guideline for early rehab

Answer 36

increase weight by 5-10% when all prescribed reps and sets can be completed easily without significant fatigue

Question 37

what are good reps and sets in early rehab

Answer 37

6-15 reps for 2 sets then 3 sets of 20-25 at constant weight until gets easy, then increase weight and decrease reps

Question 38

what can the sets and reps depend on

Answer 38

the demands of the sport and ADL

Question 39

what are the guidelines for the progression of strength training

Answer 39

1. change 1 parameter at a time (frequency, intensity, speed)
2. begin with isometrics if required
3. begin with concentric/eccentric resistance training asap, slow and controlled then increase speed
4. begin plyometric exercises once patient has met appropriate requirements
