Description of intervention(s) / exposure
Pilot 3-arm randomised controlled trial investigating the effects of Robotic-Assisted Gait Training (RAGT) in children with cerebral palsy (CP)
Arm 1: Six-week waitlist then random allocation into two or four (30-40 minute) RAGT sessions per week for six weeks.
Arm 2: two (30-40 minute) sessions of RAGT per week for six weeks
Arm 3: four (30-40 minute) sessions of RAGT per week for six weeks.
RAGT sessions: approximately 1 hour, with 30-40 minutes of this active 1:1 (individual) therapy using the Lokomat Pro in sessions conducted by the Robotics and Innovation Physiotherapist at the Women's and Children's Hospital. These sessions will be carried out at the Little Heroes Foundation Centre for Robotics and Innovation at the Women's and Children's Hospital. All sessions are conducted following the Hocoma Lokomat manual, and directions and session plans are created based on clinical reasoning by paediatric physiotherapists.
In the first session of the intervention blocks, pre-assessment data will be collected and recorded (approximately 1 hour) before an acclimatisation session in the Lokomat®Pro (30-40 minutes). Each subsequent intervention session will be 60 minutes long which will include around 10-20 minutes of heart rate and blood pressure measures, set up and fitting time, 30-40 minutes of active RAGT, and five minutes for completion of final assessments. During the active RAGT period, a range of avatar-based games and biofeedback information will be used to target different goals as determined by the COPM assessment. The three Lokomat® variables that will be adjusted regularly throughout sessions are treadmill speed, weight support and guidance force. These changes will be made subject to Borgs rating of percieved exertion scores being ideally 13. Treadmill speed would be increased, and weight support decreased if it appears the child requires an increased challenge or is progressing well between sessions. Guidance force is the amount of assistance the Lokomat® is providing the child to walk in the physiological gait pattern. This would be decreased to provide an additional challenge or as a motivational technique using the biofeedback charts. Throughout the RAGT sessions, children will be given feedback on progress as compared to previous sessions and achievements can be logged and shown in real time on the video screen. At the last intervention session, the post-assessments will be undertaken (approximately 1 hour). The assessments will be repeated six weeks after the intervention period.

Secondary outcome [6] 339278 0
Selective motor control in lower limbs
Knee:
Position: Sitting
Ask the participant to extend, flex then extend the knee while keeping the hip flexed. For example: “Straighten your knee as much as you can, then bend it and straighten again. Try to do this without leaning further back or moving your other leg. I will take you
through the motion first, and then I’
d like you to do it yourself.”
Ankle:
Position: Sitting. The knee is extended and the examiner supports the calf. Assess passive ankle
dorsiflexion ROM with the knee extended. The knee may be flexed to approximately 20 degrees if needed to accommodate hamstring and/or
gastrocnemius tightness.
Instructions –
Ask participant to dorsiflex, plantar flex then dorsiflex the ankle while maintaining knee extension. For example:
“Keeping your knee straight while I support your leg, move your foot up, down then up again. I will take you through the motion first, then
I’d like you to do it yourself.”
