| description | Functional electrical stimulation (FES) was widely used in rehabilitation for
restoring body function by stimulating the muscle with certain amount of current. An
alternative of feedback parameter for muscle activation detection was studied. A movement
feedback parameter was chosen to detect muscle activation. Two flexible bend sensors
were used to detect muscle movement. In this study, consists of three parts. First part, a
stimulator would be developed. Second part, flexible bend sensor embedded to the
stimulator for muscle movement detection. Third part, stimulator supplied current through
stimulation electrodes for muscle activation and muscle movement detected by flexible
bend sensor.
Flexible bend sensors were undergo a voluntary and non-voluntary test to observed
the voltage output change with the muscle activation relationship. For voluntary test, there
are two separate sessions. The first session, a subject was asked to cycle for 20 minutes. For
every five minutes, the first three reading displayed on screen will be recorded. The second
session, subject also need to do cycling but data recording was different. By using sampling
time of five seconds, an output voltage reading from muscle activation was recorded. For
non-voluntary test, current was supplied to vastus medialis muscle and the muscle
contraction and relaxation were recorded.
In conclusion, muscle activation can be detected by muscle movement sensed by
flexible bend sensor. Based on the basic circuit of flexible bend sensor which is voltage
divider, when muscle contracted, bending angle and resistance increased, voltage output
was low. When muscle relaxes, bending angle ad resistance decreased and voltage output
was high. |
