dosage and prescription

Question 1

2 basic concepts

Answer 1

• strength training leads to functional improvements
• failure should occur after 8th rep or patients should succeed < 80% of the time with neuromuscular tasks

Question 2

framework for modifying parameters

Answer 2

• tempo - slow movements focused on prolonged eccentric or return phase
• ROM - greater ROM
• resistance - farther from joint, increased resistance
• environment (cognitive load) - patient holds conversation or performs cognitive task
• environment (surface) - stand on softer surface, narrower BOS
• support - decrease use of UE support

Question 3

why are therabands not ideal and what is preferred

Answer 3

• TB not ideal because not consistent load through ROM, difficult to standardize
• ankle weights, DBs, weighted vests preferred - for lack of ability to hold weights, adds balance with new COM, vests enhance neuromuscular function of proximal muscles to improve stability and balance

Question 4

where is failure

Answer 4

• at 7th-9th rep - still high intensity
• lower boundary is 5 reps
• for strength gains, need > 5 reps

Question 5

decision making algorithm

Answer 5

Question 6

Borg

Answer 6

• original 6-20
• modified 1-10
• designed to monitor aerobic intensity
• accurate in multiple populations

Question 7

RPE

Answer 7

• can be less accurate when attempting to monitor intensity for strength training
• can be more accurate for experienced lifters but varies widely among patients and novice lifters
• can ask “how many more reps do you think you could have done”
