Question

1.) Good posture should minimize the energy required to maintain the body position in space.

True or False

2.) Scoliosis is typically a permanent, structural change in the postural alignment of the body.

True or False

3.) The sequence of muscle contractions in response to a perturbation in balance may differ in older and younger adults.  

True or False

4.) Postural sway decreases with age (i.e., less postural sway in a 70-80 year-old compared to a 20-30 year-old).

True or False

Answer 1

1.)

Good posture should minimize the energy required to maintain the body position in space.

TRUE

Good posture uses muscle efficiently and does not put a strain on the muscle and joint which minimize the energy requirement of the body.

2.)

Scoliosis is typically a permanent, structural change in the postural alignment of the body.

FALSE

Scoliosis can be corrected by early surgical treatment.

3.)

The sequence of muscle contractions in response to a perturbation in balance may differ in older and younger adults

TRUE

he sequence of muscle contractions of agonist and antagonist muscles in response to a perturbation in balance can differ due to different postural stability.

4.)

Postural sway decreases with age (i.e., less postural sway in a 70-80-year-old compared to a 20-30-year-old).'

TRUE

It normally due to Age-related neuro degenerative changes
