Exam 6: Resistance Exercise for Impaired Muscle Performance

A patient has mild joint swelling and pain during active ROM, but resisted tests of the muscles that cross the swollen joints do not cause pain.Your goal is to maintain or possibly increase strength through the available ROM.The most appropriate choice of exercise is:

You are having a patient perform manual resistance exercise in a PNF pattern, specifically the D₂ flexion pattern for the upper extremity.As the patient flexes the shoulder and brings the arm overhead against your resistance, what other muscle groups at the shoulder are being strengthened?

In addition to an isokinetic dynamometer, which of the following types of resistance equipment can be used safely and effectively to improve muscle strength at fast velocities of limb movement?

Each of the following is an indication that muscle fatigue is occurring when a patient is exercising against resistance except:

Mr.Z is a 68-year-old man who underwent abdominal surgery 3 months ago.Since his surgery, he has had difficulty walking.You determine that during the period of bed rest and modified activity, his legs have become quite weak, contributing to his difficulty walking.The ROM of his lower extremities is within normal limits.You determine that the 10 RM for the hip extensors and quadriceps bilaterally (measured on a bilateral leg press unit) is only 20 lb.After a brief warm-up on a stationary bicycle, you have Mr.Z perform the following PRE regimen: 10 repetitions of hip and knee extension against 20 lb; 10 repetitions against 15 lb; and 10 repetitions against 10 lb with a rest between each set of 10 repetitions.This approach to PRE is known as:

Which factors affect the amount of resistance provided by elastic resistance bands during exercise?

To selectively strengthen the flexor digitorum superficialis using manual resistance exercise, position the patient's forearm in supination and wrist in neutral on a table.What should happen next?

You are having a patient perform manual resistance exercise of the lower extremity using a proprioceptive neuromuscular facilitation (PNF) diagonal pattern.In which of the following lower extremity patterns is ankle dorsiflexion coupled with eversion resisted?

Each of the following is characteristic of DOMS except:

If the strength of a muscle is "good" (grade 4/5) and active ROM cannot be done, repetitive muscle setting exercises will accomplish each of the following except:

When an exercise involves using the same muscle group to lift and lower a constant load, such as flexing and extending the elbow while standing and holding a weight, which of the following is correct about the effect of this exercise on the tension generated by the musculature?

If a patient, who is in a prone-lying position with a cuff weight around his ankle, flexes his knee from a fully extended (0°) position to a fully flexed (150°) position, what type(s) of contraction will occur in which muscle group(s)?

Each of the following is a true statement about isokinetic exercise except:

Which of the following best defines muscle strength?

A patient is holding a piece of elastic tubing with both hands in front of the body.Both elbows are flexed to 90°, and both upper arms are held gently against the sides of the patient's chest.Instruct the patient to internally and externally rotate both shoulders simultaneously in this position.This activity strengthens the:

Mrs.B is an 87-year-old resident of Western Hills Skilled Nursing Facility.She sustained a compression fracture of the T12 vertebra several weeks ago when she inadvertently sat down forcefully on a hard chair.Incorporating resistance training that focuses on eccentric exercises of her quadriceps and gluteal muscles in weight-bearing positions (e.g., controlled squatting and partial lunges) represents what principle of therapeutic exercise?

If a patient who has an inflammatory muscle disease such as polymyositis engages in a vigorous resistance training program, it is possible that irreversible progressive deterioration, rather than improvement, in muscle strength can occur.The term that best describes this phenomenon is:

Which of the following forms of resistance training is most appropriate for a 9-year-old child with weakness of the elbow musculature as the result of an elbow sprain, followed by several weeks of elbow immobilization combined with daily active (nonresisted) ROM?

Each of the following is a true statement about muscle strength and resistance training through the life span except:

Of the following, which is the most effective way to improve muscle endurance?
