**1. Introduction**

The technological advances and the greater access to knowledge networks have generated new treatment prototypes in the health field. An ongoing technological possibility that could complement the conventional physical therapy treatment is the telerehabilitation (TR) application. TR uses new information and communication technologies as an instrument to ensure a distant rehabilitation service. In addition, this tool optimizes recovery time and saves expenses in health services, benefitting both users and healthcare professionals.

The implementation of this technology is supported by: (i) health personnel; (ii) the impact on the patient's budget and the health system (lessening the number of medical appointments and therapy sessions, decreasing the time of hospitalization, and trips to the hospital); (iii) the expansion of medical care to distant or low-income populations; and (iv) the empowerment of the patient in the rehabilitation process.

Patients who underwent hip replacement surgery are an excellent case study for the application of this technology. Total hip arthroplasty (THA) involves replacing the skeletal surfaces of the hip joint (femoral head and acetabulum).

The coxofemoral joint is one of the most important joints in the human body, because it is fundamental for walking. The rehabilitation of these patients after surgery seeks to relieve pain, restore normal function and improve quality of life. Specifically, functional recovery plays an important role to engaging patient in activities of daily living (ADL).

Post-surgical rehabilitation guidelines for hip arthroplasty are well known, and the correct application has a positive effect on the patients' prognosis. However, there are no complementary guidelines for physical therapy that could be used at a distance by patients through a computer platform. A recent systematic review shows that the TR application in real time combined with a conventional physiotherapy program is more favorable than isolated treatment of musculoskeletal dysfunctions. Thus, the objective of this chapter was to report the main results of a systematic review about conventional physiotherapy programs for hip arthroplasty and to propose some exercises adapted to a low-cost TR platform for the functional recovery. We will present a brief review of the THA, telemedicine/TR, conventional physical therapy approaches, the methodology used to design the therapeutic intervention program adapted to the low-cost TR platform from a systematic literature review, and present the initial results about the implementation of some exercises.
