Adherence to interventions
To let all subjects complete the test, we will organize experts on the subjects not less than once a week phone access, answer the questions according to measured by the number of treatment adherence, and compliance of index is set in greater than or equal to 85%, the equivalent of CG participants to answer questions not less than 11. For patients in the other intervention groups, compliance is quantified by the number of hospital-organized supervised training sessions they attended and the number of daily exercise logs they completed. Again, this compliance is set to at least 85% completion of the course or log.
