Study summary

The main objective is to assess the impact of smartphone application on adherence to a physical exercise program in chronic low back pain patients.

Adherence to a physical exercise program will be assessed at the start of the protocol, at three weeks and six months.

A control group will benefit from conventional care in a rehabilitation center and an intervention group will benefit from a conventional care in a rehabilitation center accompanied by education in the use of a smartphone application including physical exercises and information about low back pain.

The hypothesis of the search is that adherence is better in intervention group than control group at 6 months due to education in the use of smartphone application.
