Did you know that Arthritis is not a single disease? It is a way of referring to over 100 different types of joint-related conditions that cause joint pain. Estimates of Doctor diagnosed arthritis include about 54 million adults and almost 300,000 children. Arthritis makes it difficult for many to navigate their home easily. Opening a standard round doorknob and climbing stairs can be painful, or impossible for many suffering arthritis-related joint pain. Replacing round doorknobs with lever knobs, adding additional handrails in stairwells, installing grab bars, and removing carpet can help reduce arthritis-related pain and increase mobility.
