Design outcomes

Primary

Measure	Time frame
Since the feasibility of the exercises is not known, this pilot trial will only have explorative endpoints Explorative Endpoints: - Completion of every exercise session without medical termination due to pre-syncope, emesis, muscle/joint pain - An average Wong-Baker Pain rating of = 4. Feasibility of the exercise protocol will be presumed if the total number of drop outs due to presyncope is = 2 subjects per condition and average Wong-Baker Pain rating = 4.	—
