Chronic NonSpecific Low Back Pain (CNSLBP) is a common musculoskeletal condition often resulting in physical inactivity and disability. CNSLBP is associated with a large number of social and health costs, being one of the most important health problems worldwide. Although Therapeutical Exercise (TE) has been shown to be effective in increasing physical activity tolerance, physical fitness, strength, self perceived quality of live, pain tolerance, and overall physical activity participation levels in persons with CNSLBP, pain-release-passive therapy modalities are significantly more commonly used in clinical settings at present. On the other hand, the use of tele-assistance platforms PTAs has been gaining importance in the treatment of CNSLBP patients, especially in the use of semi-directed TE programs. However, current PTAs are not accessible for the visually impaired, a group that is at greater risk of suffering from sedentary lifestyles, restricted mobility and musculoskeletal pain due to postural or gait changes. The main hypothesis of these study is that a semi-directed TE and health education programm, in people with and without visual impairment, achieves better results in movement capacity, functional recovery, strength and compared to passive analgesic treatment in patients with CNSLBP. In a second objective, we will assess the efficacy and usability of a new PTA accesible tool for the follow-up of patients with CNSLBP who are visually impaired.
