“…In our previous study, we proposed a hand exoskeleton that can assist both the extension and flexion of the fingers using a rigidsoft combined mechanism (Li et al, 2019). Please note that the hand exoskeleton was not used to provide kinesthetic feedback of the interaction between the fingers and the virtual objects [like the haptic exoskeletons in (Secco and Maereg, 2019;Wang et al, 2020)] but to provide movement assistance to the hand. Each finger is driven by one actuator containing a linear motor, a steel strap, and a multi-segment mechanism (see Figure 1C).…”

Active enrollment in rehabilitation training yields better treatment outcomes. This paper introduces an exoskeleton-assisted hand rehabilitation system. It is the first attempt to combine fingertip cutaneous haptic stimulation with exoskeleton-assisted hand rehabilitation for training participation enhancement. For the first time, soft material 3D printing techniques are adopted to make soft pneumatic fingertip haptic feedback actuators to achieve cheaper and faster iterations of prototype designs with consistent quality. The fingertip haptic stimulation is synchronized with the motion of our hand exoskeleton. The contact force of the fingertips resulted from a virtual interaction with a glass of water was based on data collected from normal hand motions to grasp a glass of water. System characterization experiments were conducted and exoskeleton-assisted hand motion with and without the fingertip cutaneous haptic stimulation were compared in an experiment involving healthy human subjects. Users’ attention levels were monitored in the motion control process using a Brainlink EEG-recording device and software. The results of characterization experiments show that our created haptic actuators are lightweight (6.8 ± 0.23 g each with a PLA fixture and Velcro) and their performance is consistent and stable with small hysteresis. The user study experimental results show that participants had significantly higher attention levels with additional haptic stimulations compared to when only the exoskeleton was deployed; heavier stimulated grasping weight (a 300 g glass) was associated with significantly higher attention levels of the participants compared to when lighter stimulated grasping weight (a 150 g glass) was applied. We conclude that haptic stimulations increase the involvement level of human subjects during exoskeleton-assisted hand exercises. Potentially, the proposed exoskeleton-assisted hand rehabilitation with fingertip stimulation may better attract user’s attention during treatment.

Impairments in the sensorimotor system negatively impact the ability of individuals to perform daily activities autonomously. Upper limb rehabilitation for stroke survivors and cerebral palsy (CP) children is essential to enhance independence and quality of life. Robot assisted therapy has been a bright solution in the last two decades to promote the recovery process for neurological disorders patients. Nevertheless, defining the optimum intervention of robot assisted therapy (RAT) in different cases is not clear yet. With this aim, the presented study reviewed the current literature on RAT protocols for upper limb impairments and the effects of RAT on recovery outcomes. A literature search was conducted using different search engines, reviews, and studies. This study presents an overview of fourteen robotic devices used in the rehabilitation field and seventeen clinical trials using commercially available devices during the last three years. A discussion about reaching an efficient rehabilitation process based on different aspects such as clinical setting and training modes has been introduced. This review identifies the limitations of RAT to lay the foundation for more effective neuromotor disorders rehabilitation. Finally, using virtual reality (VR) as an assisting feature in RAT improves the whole process of recovering motor functionality.

Virtual Reality (VR) has been used in several areas such as video games, technical training, movies and teaching. VR-based interventions have also been applied for motor rehabilitation, e.g., to help the patient recovery from disabilities provoked by stroke, cognitive deficit or musculoskeletal problem. VR combined with wearable tracking devices creates new possibilities to apply immersive approaches during motor rehabilitation. This can enhance the health care making it more interesting and pleasant for patients as well as more effective for physicians and physiotherapists. However, the costs related to this technology may be impracticable for a wide application by public health system. Therefore, this paper introduces preliminary results for a low-cost wearable device, which is integrated to VR environments aiming to provide a better quality rehabilitation process for most patient with motor disabilities.
