Design
The study was designed as a feasibility study. The term
feasibility study refers to studies that are carried out in preparation
for future large-scale definitive studies such as randomised trials
or observational studies, and to address key issues of uncertainty14
– in this case, uncertainty related to the home-based use of the
BandcizerTM system. The study investigated whether the exercise
monitoring system could be used to record exercise dosage and
pain, to test whether adolescents with patellofemoral pain perform
their exercises as prescribed, and to test whether they report their
adherence accurately in their exercise diary. This was tested
among 20 adolescents with patellofemoral pain that were
prescribed 6 weeks of exercises.
