Ch. 6 Pros and Cons

1)    Needs Served By Seating Evaluation for Seating

Some pros are seating for postural control, seating for tissue integrity and seating for comfort. Their impaired motor control affects their ability to participate in activities of daily living. A bad thing is that individuals lose motor control as a disease progresses. It helps individuals with seating who are usually for people who have abnormal muscle tone, muscle weakness, primitive reflexes, or uncoordinated movements that impair their ability to maintain an upright posture in a wheelchair.

 

2)    Biomechanical Principles

Biomechanics is the study of body position and movement. There are so many positive outlooks on biomechanics which helps aid individuals with disabilities. Kinematics which is the study of motion describes the movement. Displacement is defined as the position of a body in space. Force is a plus in biomechanics and seating, it is anything that acts on a body to change its rate of speed. I guess the only negative thing would be stress.

 

3)    Principles of Seating For Postural Control

It is caused by children and adults who have irregular tone, muscle weakness, abnormal reflex patterns, shortening of a muscle group that will help control their posture and prevent deformities. Sometimes it only require minimal support whereas other individuals may have severe impairment and require extensive postural support. Some positive things would be it provides support to the body to improve skeletal alignment, normalize tone, prevent deformities and enhance movements.

 

4)    Principles of  Seating For Tissue Integrity

This has a lot do with pressure management. It is to manage sitting pressure and maintain the skin in a healthy condition so that lesions will not occur. The negative thins it can cause lesions which are very painful known as pressure ulcers. It can result in damage to underlying tissue.

 

 

5)    Principles of Seating for Comfort Technologies for  Seating and Positioning Management

The people who can benefit from this are wheelchair users who have sitting discomfort and pain, the elderly and individuals with low back pain. One con about this is that it is not funded by third party sources because they don’t believe it is a necessity.

 

6)    Properties of Materials Used To Construct Seating Systems

There are five principles that defines on how to construct a seating system which are density, stiffness, resilience, dampening and envelopment. Density is the ratio of its weight to volume. Low density materials will fatigue faster. With stiffness soft materials may bottom out, but failure to compress can also lead to an increase in seating pressures and tissue breakdown. In other words weight bearing causes a lot of damage to the area.

 

 

7)    Seating for Pressure Distribution and Postural Support

This is for people who are at risk for development of pressure ulcers benefits from this. A cushion, without a firm base, placed in the seat will eliminate all pain.
