Chase Trainer Exercise Program in Athlete with Unilateral Patellofemoral Pain Syndrome (PFPS)

We investigated the effects of modified
preprogrammed training mode Chase Trainer from Balance Trainer
(BT3, HurLab, Tampere, Finland) on athlete who experienced
unilateral Patellofemoral Pain Syndrome (PFPS). Twenty-seven
athletes with mean age= 14.23 ±1.31 years, height = 164.89 ± 7.85
cm, weight = 56.94 ± 9.28 kg were randomly assigned to two groups:
experiment (EG; n = 14) and injured (IG; n = 13). EG performed a
series of Chase Trainer program which required them to shift their
body weight at different directions, speeds and angle of leaning twice
a week for duration of 8 weeks. The static postural control and
perceived pain level measures were taken at baseline, after 6 weeks
and 8 weeks of training. There was no significant difference in any of
tested variables between EG and IG before and after 6-week the
intervention period. However, after 8-week of training, the postural
control (eyes open) and perceived pain level of EG improved
compared to IG (p<0.05). The postural control with eyes closed of
EG improved (p<0.05) but the values were not significantly different
compared to IG after training. The results suggest that using Chase
Trainer exercise program it is possible to improve individual postural
control and decreased perceived pain level in athlete with unilateral
Patellofemoral Pain Syndrome (PFPS).
