Background and study aims
Cerebral palsy (CP) is a term for a number of conditions that affect movement and co-ordination. It occurs when there is a problem in the parts of the brain responsible for controlling muscles. This can be due to abnormal development of the brain or damage caused before, during or after birth. CP leads to a range of symptoms, including muscle stiffness or weakness, random and uncontrolled body movements and balance and coordination problems. Problems with walking (gait) are the most common problems seen in children with CP. Robotics are being used more and more to help people who have problems with movement. The CPWalker rehabilitation platform is a robotic device made up of a walker and an exoskeleton (device worn on the outside of the body), which provides support and guidance to patients while they can experiment with walking techniques. The device can tprovide body weight support and the exoskeleton allows different control modes in order to adapt the therapy to the patient's needs. The aim of this study is to find out if therapy involving robot-based walking sessions can help children with CP to improve their gait (walking ability).
Who can participate?
Children aged 11 to 18 years who have cerebral palsy.
What does the study involve?
All the participants receive 16 robot-based walking sessions of 70 minutes each, distributed over two months with training on two non-consecutive days per week. The patients are free to also take part in other conventional rehabilitation therapies while they are taking part in the study. The first eight sessions focus mainly on general control of movement and strength training exercises, and the second eight sessions focus on increasing independence. At the start of the study and then after eight and 16 weeks, participants undergo a range of assessments to find out if their gait and wellbeing has changed.
What are the possible benefits and risks of participating?
Participants may benefit from improving their gait (walking ability) function and speed, which could improve their quality of life. There is a small risk of muscle pain and tiredness after the therapy sessions with the robot.
Where is the study run from?
Hospital Infantil Universitario Niño Jesús (Spain)

| Scientific title | Assessment evolution of a defined over-ground robot-based therapy in four children with Cerebral Palsy using the CPWalker robotic platform |
| Study objectives | The implementation of strength and power robot-based exercises at the same time than overground walking guidance, and performing in parallel an active head-trunk control therapy, will boost the rehabilitation of children with Cerebral Palsy. |
| Ethics approval(s) | Local Ethical Committee of the “Hospital Infantil Universitario Niño Jesús”, 26/06/2012, ref: R-0032/12 |
| Health condition(s) or problem(s) studied | Cerebral palsy |
| Intervention | Four children with CP are recruited to train with a robotic platform (CPWalker) two non-consecutive days per week for eight weeks (16 total sessions). The sessions consist of a 10-15 minutes warm-up and 60 minutes of over-ground exercise with CPWalker, including 3 minutes of independent gait as a cool-down phase. The first eight sessions correspond with general motor control and strength exercises, where the robot imposed a gait trajectory tracking. Sessions 9 to 16 are related to muscle power performance through levels of AAN strategies, where self-activity was required. All children undergo assessments at baseline, after 8 weeks and after 16 weeks. |
