What can be increased by widening the base of support?
For increased stability while standing, the feet should be spread apart, giving a larger base of support. Stability is also increased by bending the knees, which lowers the center of gravity toward the base of support. A cane, a crutch, or a walker increases the stability of the user by widening the base of support.
Why would someone have a wide base of support?
A wide base of support is the foundation for stability. A wide base of support is achieved by placing feet a comfortable, shoulder width distance apart. When a vertical line falls from the centre of gravity through the wide base of support, body balance is achieved.
What does base of support mean?
The base of support (BOS) refers to the area beneath an object or person that includes every point of contact that the object or person makes with the supporting surface. These points of contact may be body parts e.g. feet or hands, or they may include things like crutches or the chair a person is sitting in.
Why does your center of mass have to be over your base of support?
With the centre of mass directly over the base of support, the weight will be felt back in the middle of the foot. Doing heavy two armed or barbell front raises is not recommended because the load you are lifting in front of you will increase and often move your centre of mass outside of the base of support.
What is the longest nerve?
Sciatic Nerve Anatomy

- The sciatic nerve originates in the lower spine and is responsible for motor and sensory functions of the lower body.
How fast does a human brain work?
When you are awake, your brain generates about 12-25 watts of electricity – which is enough to power a small light bulb. The brain also works fast. The information going from your arms/legs to your brain travels at a speed of 150-260 miles per hour.
