Virtual Reality During Hemodialysis

Virtual Reality Exercise During Hemodialysis

The main objective of this investigation is to assess if an intradialysis virtual reality exercise-based program results in an improvement in physical function and if it results in high adherence rates to exercise. The secondary aim is to assess the effect of intradialysis VR in physical activity level, health related quality of life and in cognitive function.

Participants will be randomized into one of two groups. The first group will start with 12 weeks of virtual reality exercise during hemodialysis and will carry on with a control period of 12 weeks. The second group will start with a control period of 12 weeks (no exercise) and will carry on with a virtual reality exercise period of 12 weeks.

The virtual reality exercise will undertake up to 30 minutes of exercise. After warming up, participants will play to an adapted 'treasure hunt' game. Their legs movements will be the players projected into an individual tv that will give them feedback regarding their achievements. The aim of the game will be to achieve the higher possible score.They will move their legs to pick up coins and to avoid bombs. An adapted Kinect technology will be used for the game development. The exercise session will end-up with a cool-down period that will include simple lower limb stretching exercises.

Inclusion Criteria:

• At least 3 months in hemodialysis treatment
