Many people suffer from mobility issues, which can range from minor mobility impairment with a minimal impact on daily life, through to impairment severe enough to cause ongoing pain and a range of practical difficulties that make daily life a challenge.

Walking difficulties or unsteadiness are common issues, especially in older people. It may be a short-term injury, or due to a more serious illness. If someone falls ill for a long time or becomes disabled, they may be unable to move around as before. In addition to the problems directly relating to their illness or disability, if a person becomes immobile for any length of time, there are additional risks, such as development of further medical conditions, poorer quality of life, and a greater likelihood of social isolation.
