Hemiplegia and hemiparesis are life-altering conditions that lead to secondary effects including pain and health decline due to sedentary lifestyle. There exists a need for affordable, safe, and effective exercise equipment designed with these users in mind. Recent studies have demonstrated adaptability of post-stroke individuals to differential forces in a split belt treadmill regime, resulting in increased propulsive force generation of the paretic limb. An elliptical exercise machine with a differential resistance mechanism, free-wheeling motor assistance, and walker accessibility has been fabricated to test whether differential resistance is possible with an elliptical platform. Preliminary testing of 1 subject consisted of elliptical training at different machine settings. Reaction force data indicated this effect is achievable and scalable as a function of the adjustable mechanism. These findings show promise for future investigations with greater sample size, and offer insights for refinement of the differential resistance elliptical prototype.
