Learn appropriate terminology.
You need to use the right words when discussing with people with disabilities. Some terms once considered the norm, but now have become obsolete and even offensive. The first step is learning how to use the right words if you want to help people with disabilities.
When we talk about people with disabilities, will be more polite if you’re their human than special circumstances. For example, do not say “people with mental illness” or “mental illness”. Instead, say, “People with mental illness.” Also do not say “wheelchair”. Identify them by another means you think you can do that to any, even want to talk about the specific function of the wheelchair, they may say, “the wheelchair” or “people are taking car roll”. Keep in mind a few exceptions; many people who are deaf, blind, or autism often use language recognition locally, ie they want to be called “autistic” or “Deaf” (uppercase letter K in accordance with their rules).
Some appropriate phrase is now obsolete and even offensive. From “dumb” was used to refer to people who do not speak, but now tend to use the phrase “can not afford to say” or “people to use voice synthesizers”. From polio have been used to describe people with physical disability, limited mobility, now tend to use the phrase physical disability than
from “disability” and “retarded” are from offensive. We can replace it with the phrase people with intellectual disability, development, or cognitive. Ever more people use the word “disability” but now deprecated because it is a serious insult to the disabled.
Typically, people with disabilities are interpreters, nurses, friends support daily. It is important when dealing with people with disabilities is that you have to talk directly with them. Do not exchanged indirectly through another person.
Looking directly at the person, not the interpreter or their assistants. Typically, the deaf will observe their interpreter when other people talk to understand conversations. You should still look at the people you need to talk, not the interpreter.
If you talk to people in wheelchairs, sit down so they do not have to stock up at your backs. Do not kneel as if talking to a child because of this action looks very odd.
Consulted before support. If you encounter a person with a disability is struggling with something, then instinctively you will jump in to help. However, if you do not know the needs and the specific intent of the act then help is not necessarily appropriate. You should consult them before support.
Many people with disabilities look like struggling but they are completely wrong. Just that they take more time to do it, does not mean they need your help. If you think they need help, you can ask directly. 
If you see someone in trouble, you might ask, “Do you need help?” or “Do you need me to support it?” Do not say anything more.
If he refuses to help you, do not feel offended or deny that let themselves behave as normal.  They understand their own needs better than anyone else, forcing them may be considered rude.
Do not give medical advice, especially if you’re not a doctor. Chronic pain sufferers suggest yoga may seem useful, but they have a doctor who knows your medical history and give advice without pretending anything
Speak and behave with respect. When interacting with people with disabilities, you have always shown respect in word and action.
When being introduced to people with disabilities, always request a handshake. Even with limited arm movement, they still can manage it.
This is the polite gesture and attract their attention.
Talk to the tone as usual. People often speak slowly and louder than usual, especially when communicating with deaf people, but this is an act rude and childish. Please communicate normally.
Do something to communicate more easily than normal. For example, if you interact with people who are hard of hearing, please look at them so that they can read and understand export shaped mouth what you say. Sit down and make eye contact with people in wheelchairs as a polite gesture. For people not able to speak, instead of pretending to understand what they say, you can politely ask them to repeat themselves.
Be yourself in the conversation. If you accidentally use to communicate are often right, such as saying “see you again” with the blind, do not panic and apologize profusely. He understands this is an intimate gesture, and you did not mean to offend them.
Make a question.
We often worry whether you inadvertently offend people with disabilities should be embarrassed when communicating. This can be considered as the distance for the disabled, so you have to be yourself and really calm. If you have any questions, ask them if related to the current situation.
Often people with disabilities want you to put them instead politely ask themselves such embarrassment. For example, you can ask a totally deaf if they can say the mouth shape and you can see their face when talking or not. If you are planning events and ramps for wheelchairs at the end of the room, you absolutely can ask, “Do you know the way for wheelchair anywhere? It was a little bit hard to find, I just wanted to make you aware place. “
People are often afraid to ask questions because they do not want to attract the attention of people with disabilities. However, avoid the obvious questions: sometimes attract attention than to ask directly. As long as the question relating to the current situation, they will not consider it curious questions or sensitive.
