Modern advances in technology have allowed for an increase in the precision with which
we are able to measure, record, and affect behavior. These developments suggest that the
domains in which behavior analysis might contribute are considerably broader than previously
appreciated, for instance the area of behavioral medicine. One way the field of behavior analysis
can begin to address problems in behavioral medicine is with biosensor technology, like surface
electromyography (sEMG). For sEMG technology to be useful in behavioral medicine,
specifically recovery from total knee arthroplasty, a reference value (the maximum voluntary
individual contraction-MVIC) must be established. The MVIC value allows for the comparison
of data across days and may allow the programming of contingencies. However, current MVIC
methods fall short. Study 1 compares MVIC values produced by a participant given the typical
instruction only method with two alternative methods: instruction + feedback, and instruction +
feedback in a game context. Across 10 participants both feedback conditions lead to higher
MVIC values then the instruction only condition. Study 2 applies the MVIC techniques
developed during Study 1 to an exercise procedure. Using an MVIC value as the criteria for
feedback Study 2 compares the same three conditions, however this time assessing for the
conditions under which exercise performance is optimal. Across all 9 participants the instruction
+ feedback in a game context lead to the participant 'working harder' and 8 out of 9 participants
exceeded the MVIC value more often during this condition then in the other two conditions.
