Pilot feasibility study of Exercise in grade III and IV High Grade Glioma (glioblastoma & anaplastic astrocytomas) while undergoing up-front Radiation with or without chemotherapy (EGGR study)

Usual medical care Plus A fourteen-week structured physical activity programme. - participant will meet a dedicated physiotherapist at the hospital, three times each week (1hr) for seven weeks. After this participant can decide whether to meet face to face or talk over the telephone, weekly, for another seven weeks. (duration of session time depends on participant) - participants are give a brief diary to fill out and a pedometer (a small device that counts the number of steps you take during the day). - During the first seven weeks they will take part in a supervised physical activity program at the treating hospital (1hr or shorter if participant is not able to do a full hour). As part of this program they will do some fitness, strength and balance exercises under the supervision of the exercise provider. These exercises are provided individually but may at some time be performed in a group. - If participants are not able to do the activities this can be adapted to them, intensity is individualised for each participant In weeks 8-14 patients receive a one on one supervised exercise session and are expected to perform daily exercise at home (amount of time to what the patient feels comfortable with). From weeks 14-21 patients are required to perform exercise daily at home independently. (this can be similar exercises to what they have been doing or other forms of exercise they feel comfortable with. For the physical activity: a) exercise intensity is measured by the RPE borg Scale. b) exercises are chosen based on the patients level of function. They include a cardio component eg: cycling, walking, treadmill. Strength component and balance. Intervention is individualised for each patient based on their mobility, strength, co-morbidities and desired outcomes of exercise.
