Improving healthy habits such as sleep, nutrition or physical activity is expected to enhance rehabilitation in knee or hip arthroplasty patients, by increasing their ability to attend and adhere to rehabilitation recommendations following surgery. Half of the subjects in this study will be assigned to an intervention that meets with a study therapist to discuss implementing healthy habits (physical activity, nutrition, pain-coping techniques, etc). The other half of subjects will assigned to an intervention group that meets with a study therapists to discuss implementing healthy sleep habits. Both groups will undergo several physical and cognitive assessments at baseline (prior to surgery), post-hospital, post-intervention and at a 6 month follow-up visit.
