The main objective of the study is to assess the feasibility of a randomized clinical trial that investigates the effects of an 8-week group exercise program on pain, disability, fear of falling, overall impression of recovery, frequency of falls and level of physical activity in elderly people with nonspecific low back pain. The evaluation of feasibility will be related to: (1) blinding the evaluator to allocate the groups; (2) eligibility and recruitment rates; (3) acceptability of random allocation to a group; (4) possible contamination between groups; (5) adherence to treatment; (6) satisfaction with the treatment; and (7) difficulty in understanding the information provided by the physiotherapist.
