“…During the experiment with nondisabled participants, tracking was done using three different control modes: discrete, semiproportional, and proportional command [28]. Our previous work [35] led us to conclude that the discrete mode is the most robust control paradigm given the current status of the TDS-HM hardware and signal processing algorithm, and therefore this was used with the participants with stroke.…”

“…Six nondisabled individuals simulated UL impairment, allowing us to test the functionality of the TDS-HM system in terms of ease of use and robustness of the different modes of operation [28]. Specifically, we looked at whether training with TDS-HM would result in RMSE reduction over the course of three sessions in nondisabled participants.…”

“…The user attempts to move the paretic hand while using the tongue to drive motion; however, active motion of the wrist and hand is not necessary to drive the unit. The technical details of the TDS-HM design have been previously published [28].…”

Abstract-Stroke survivors with severe upper limb (UL) impairment face years of therapy to recover function. Robotassisted therapy (RT) is increasingly used in the field for goaloriented rehabilitation as a means to improve UL function. To be used effectively for wrist and hand therapy, the current RT systems require the patient to have a minimal active range of movement in the UL, and those that do not have active voluntary movement cannot use these systems. We have overcome this limitation by harnessing tongue motion to allow patients to control a robot using synchronous tongue and hand movement. This novel RT device combines a commercially available UL exoskeleton, the Hand Mentor, and our custom-designed Tongue Drive System as its controller. We conducted a proof-of-concept study on six nondisabled participants to evaluate the system usability and a case series on three participants with movement limitations from poststroke hemiparesis. Data from two stroke survivors indicate that for patients with chronic, moderate UL impairment following stroke, a 15-session training regimen resulted in modest decreases in impairment, with functional improvement and improved quality of life. The improvement met the standard of minimal clinically important difference for activities of daily living, mobility, and strength assessments.

“…We have demonstrated that tongue motion, if properly harnessed, can be used to communicate human intent and to assist in controlling a rehabilitation robot or an assistive device [27,28]. The tongue has several advantages compared with the other methods of intention detection and control of rehabilitation devices.…”

“…In a previous study, a tongue-operated rehabilitation robot has been developed to translate tongue motion to commands via the tongue drive system (TDS) [43][44][45][46]. Commands were used to control a wrist-based rehabilitation robot called the hand mentor [27,47]. This device has been shown to elicit improvements in strength and range of motion in moderate to severely impaired stroke survivors [28,48].…”

Stroke is a devastating condition that may cause upper limb paralysis. Robotic rehabilitation with self-initiated and assisted movements is a promising technology that could help restore upper limb function. Previous studies have established that the tongue motion can be used to communicate human intent and control a rehabilitation robot/assistive device. The goal of this study was to evaluate a tongue-operated exoskeleton system (TDS-KA), which we have developed for upper limb rehabilitation. We adopted a tongue-operated assistive technology, called the tongue drive system (TDS), and interfaced it with the exoskeleton KINARM. We also developed arm reaching and tracking tasks, controlled by different tongue operation modes, for training and evaluation of arm motor function. Arm reaching and tracking tasks were tested in 10 healthy participants (seven males and three females, 23–60 years) and two female stroke survivors with upper extremity impairment (32 and 58 years). All healthy and two stroke participants successfully performed the tasks. One stroke subject demonstrated a clinically significant improvement in Fugl-Meyer upper extremity score after practicing the tasks in six 3-h sessions. We conclude that the TDS-KA system can accurately translate tongue commands to exoskeleton arm movements, quantify the function of the arm, and perform rehabilitation training.
