Hi there,
We're doing a research project measuring back strength in patients before
and after spinal fusion surgery. We have a back attachment that attaches to
our Biodex and allows us to measure back strength in the lumbar region doing
a flexion/extension isokinetic test while the subject is semi-standing. The
other test we are doing is an isometric lateral bending test measuring
oblique strength. We would like to make sure that our patients are not
cheating and using other muscles, such as the rectus femoris, hamstrings,
gastrocs and gluteus medius, to assist them in doing these exercises. We
have thought about monitoring EMG for these muscles while they are
performing the exercises, but we need instantaneous feedback while the
patient is still in the lab. If we collect the EMG data, we have to go
through the process of reducing it and then make a decision on whether the
subject was using their other muscles too much. So we are looking for
something that will tell us right away whether or not the subjects are
cheating when they are performing the test. Any ideas on this matter or any
literature that anyone could point me to would be appreciated.
Thank you for your help.
Sincerely,
