“…Thus, the actual role of robot-assisted therapy in poststroke rehabilitation remains to be clarified, and to date, no guidelines exist on how the design and use of such devices might increase their efficacy [23]. One domain to be explored is acute-phase robotic therapy.…”

Abstract-The successful motor rehabilitation of stroke patients requires early intensive and task-specific therapy. A recent Cochrane Review, although based on a limited number of randomized controlled trials (RCTs), showed that early robotic training of the upper limb (i.e., during acute or subacute phase) can enhance motor learning and improve functional abilities more than chronic-phase training. In this article, a new subacute-phase RCT with the Neuro-RehabilitationroBot (NeReBot) is presented. While in our first study we used the NeReBot in addition to conventional therapy, in this new trial we used the same device in substitution of standard proximal upper-limb rehabilitation. With this protocol, robot patients achieved similar reductions in motor impairment and enhancements in paretic upper-limb function to those gained by patients in a control group. By analyzing these results and those of previous studies, we hypothesize a new robotic protocol for acute and subacute stroke patients based on both treatment modalities (in addition and in substitution).Clinical Trial Registration: ClinicalTrials.gov; NCT01102309, "Robot-assisted rehabilitation of the upper limb in acute and subacute poststroke patients"; http://clinicaltrials.gov/ct2/show/ NCT01102309.

“…In addition, constraints representing power transmission should be added to the design analysis to further optimize the design for force transmittance. An actuator would then be selected based on the force profiles that would be powerful enough while still maintaining the high compliance needed to allow kinematic errors [20]. Other sensors would also be added as required by the controller.…”

“…In order to answer that question, a control approach was designed in [18]- [20] based on the idea of increasing the effectiveness of robotic rehabilitation therapy by promoting neural-muscular participation of the subject. The developed -assist-as-needed‖ controller reduces assistance as the subject is able to complete a desired movement.…”

This paper presents a design method for a reconfigurable single degree-of-freedom mechanism for robotic assisted finger therapy following a stroke. The mechanism is a four-bar linkage that in combination with variable link lengths is capable of reproducing a power grasp finger motion for a wide variety of finger sizes. This is accomplished through an optimization procedure that determines the parameters of the four-bar linkage needed to fit the sampled range of finger trajectories. The linkage is located behind the hand and attaches to the medial phalanx of the finger just above the distal interphalangeal joint. In addition, the mechanism is designed so that it does not interfere with finger motion and so that the subject's fingertips and palm are free to touch real objects and experience tactile feedback. In future implementations, the mechanism could be used for a single finger or in parallel with other similar mechanisms to exercise multiple fingers simultaneously. Although the specific application presented here is the four-bar mechanism and finger power grasp motion, the developed design methods may be applied to a much broader range of mechanisms and applications where scalability for human-machine interface is required.

“…In addition, the used of robotic devices for neurorehabilitation can lead to similar or larger improvement motor function that traditional therapy 3 . In particular, MIT-Manus 4 and two degree of freedom (DOF) elbow-shoulder robot 5 , which were developed for unrestricted unilateral shoulder and elbow movements in horizontal plane, show that additional therapy aided by robot technology can improve motor function.…”

Stroke is the leading cause of disability. Reaching movement is the most important movement for many daily activities routine. Rehabilitation is to encourage and enhanced recovery process. Conventional rehabilitation is one-to-one intervention where labour intensive and lack of repeatability. In addition, the stroke assessments by physiotherapist are subjective and not independent. Thus, this paper will describe the design and development of non-motorized system for assessing the patients' motor function. This system will be used in the future to find the correlation between conventional assessments scales such Fugl-Mayer Assessment (FMA), Chedoke-McMaster Stroke Assessment Scale (CMSA) and Motor Assessment Scale (MAS) and robotic assessment.
