Abstract
Muscular fatigue affects the muscle activation that is needed for producing the
desired clinical outcome. Integrating optimal muscle relaxation periods into a variety of
health care rehabilitation protocols is important to maximize the efficiency of the therapy.
In this study, four muscle relaxation periods (30, 60, 90 and 120 seconds) and their
effectiveness in producing consistent muscle activation of the muscle biceps brachii
between sets of an elbow flexion and extension task was investigated among a sample of
10 subjects with no disabilities. The same resting periods were then utilized in a
controlled exoskeleton-based exercise for a sample size of 5 subjects and have shown
similar results. On average, the muscle activity of the biceps brachii decreased by 0.3%
when rested for 30 seconds, and it increased by 1.25%, 0.76% and 0.82% when using
muscle relaxation periods of 60, 90 and 120 seconds, respectively. The preliminary
results suggest that a muscle relaxation period of about 60 seconds is needed for optimal
continuous muscle activation within rehabilitation regimens. Robot-based rehabilitation
is good to produce repetitive tasks with the right intensity and knowing the optimal
resting period will make the automation more effective.
