Why is it important to know the center of gravity in wheelchair users?
Press to flip
Knowing the center of gravity in wheelchair users is important for designing and ensuring the stability of the wheelchair, especially considering the leg position.
Describe the changes in center of gravity when bending over.
When bending over, the center of gravity moves forward and downward, potentially outside the body.
What is the effect of a higher center of gravity on stability?
A higher center of gravity reduces stability.
How does reaching for an object affect your center of gravity?
Reaching for an object shifts your center of gravity from a symmetric position to the weight-bearing foot.
What are the contributing factors from the central nervous system (CNS) in maintaining balance?
The CNS processes information and triggers movement, which are crucial for maintaining balance.
Explain the importance of the base of support in relation to stability.
The base of support is the area of contact with the ground, which is critical for stability. A wider base of support increases stability.
Discuss how an amputee's center of gravity might affect their stability.
Amputees typically have a higher center of gravity, which can lead to increased instability.
Why is it important to understand the concepts of CG and base of support when training patients for safety and stability?
Understanding these concepts is crucial for preventing falls and ensuring that patients can move safely and stably, particularly in therapeutic settings.
What defines the center of gravity (CG) in the human body?
The CG is the balance point where the three movement planes intersect, typically located around the navel when standing upright.
What happens to your center of gravity if you have strong lower extremities compared to a well-built upper body?
If you have strong lower extremities, your center of gravity will be lower. If you have a well-built upper body, your center of gravity will be higher.
How does the sense of sensation contribute to balance?
Sensation is key for accurate judgment and maintaining balance.
Identify a special consideration for stroke patients in terms of balance and stability.
Stroke patients face an increased fall risk due to weakness and impaired sensation on one side.
How does standing on one foot affect your center of gravity and stability?
Standing on one foot reduces stability because it decreases the base of support and can destabilize the center of gravity.
How does the body's position and movement affect the center of gravity?
Changes in body position and movement, such as raising arms or bending over, affect the location and stability of the center of gravity.
How does raising your arms affect your center of gravity?
Raising your arms moves your center of gravity higher.
