Ageing of the population influences all parts of the society including health, education, socio-cultural activities social security and family life. The financial and social outcomes of population ageing are clarified by changes in lifecycle behaviour. Population ageing is generally the aftereffect of demographic momentum, so policy proposals should address the outcomes of these patterns instead of endeavor to change the patterns themselves yet, the developing diversity of circumstances among the elderly people and the limit of families to give care over generation’s influence how the strategy implications of an ageing population will play out. The proportion of the nation's population more than 65 as a percentage of aged 20-64 (the elderly dependency proportion) is required to increment from 20.9% in 2010 to 58% in 2050 and 70.7% in 2060 while the offer of the working age populace (15-64) is anticipated to drop from 71.3% in 2010 to 53.4% by 2050. These patterns spell potential economic inconvenience for Ageing.

With increased age, patients regularly confront numerous emotional and physical changes that can influence level of functionality and well-being. Rehabilitation keeps up functional independence in the elderly. Rehabilitation of geriatric patients is basic for the patients' wellbeing and for society. Geriatric rehabilitation additionally have a role in transitional care, where patients are alluded by a hospital or family doctor, when there is a prerequisite to give hospital based short term intensive physical therapy went for the recuperation of musculoskeletal function, especially recovery from joint, ligament, or tendon repair. Lastly, geriatric rehabilitation impacts the growing life expectancy around the world. Adherence to an activity program impacts frailty, speed, ability to live independently, and the best part is life expectancy. The geriatric rehabilitation combines an extensive variety of medications and therapeutic help for a variety of ailments that the aged face. Geriatric rehabilitation incorporate exercise, assistive technologies, adaptive techniques, physical modalities, and orthotic (braces, splints) and prosthetic devices. Rehabilitation is a basic part of geriatric healthcare, on the grounds that debilitating conditions, which are normal among older adults, significantly influence their quality of life and are manageable to treatment.

Significant developments in wellbeing and social prosperity have prompted linear gains in life expectancy and a going with increment in the burden imposed by age-related morbidities.
