Q

The goal of this exercise is to increase the flexibility (extensibility) of the pectoralis major muscle. You teach the patient to stand facing a corner with the shoulders abducted to 90°, elbows flexed to 90°, and hands and forearms placed on the walls. You tell the patient to relax into the stretch (by leaning into the corner) for 30 seconds; push his forearms into the walls for a count of six; then relax and lean forward toward the corner again and hold for 30 seconds. The self-stretching technique the patient is using is:

A

Hold–relax (contract–relax).

Q

During a stretching maneuver, you apply a 30-second stretch of a shortened muscle group just up to the point of tissue resistance. After this maneuver, rather than relaxing with the patient and returning the body segment to a neutral position, you move the body segment into the newly gained range to apply another stretch of the same muscle group and hold the stretch for an additional 30 seconds. What term best describes this type of stretching?

A

Static-progressive
