The system described in this paper combines virtual reality with haptic feedback to increase the level of immersion and invoke the sense of agency in patients with phantom limb pain with the aim of reducing perceived pain. This paper presents three case studies of an on-going clinical study. The initial results suggest an increased sense of embodiment of the virtual limb promotes a decrease in perceived...
The main focus of spasticity treatment is to alleviate pain, improve function and reduce risk of additional complications. In this paper the design of a robotic system with enhanced focal vibro-tactile stimulation for the treatment of spasticity in the upper limbs is presented. Building on emerging evidence on the use of vibrations in the treatment of spasticity, we propose a new integrated approach...
Spinal cord injury (SCI) typically manifests with a loss of sensorimotor control of the lower limbs. In order to overcome some of the disadvantages of chronic wheelchair use by such patients, robotic exoskeletons are an emerging technology that has the potential to transform the lives of patients. However, there are a number of points of contact between the robot and the user, which lead to interaction...
This paper presents a single case study of an on-going study evaluating cortical association with facilitation and management of vibro-tactile stimulation applied prior to voluntary muscle contraction. The study consisted of three repetitions of relaxation phase during which vibrations are applied, and a contraction phase. EEG and EMG data was collected to determine muscle and brain activation patterns...
This paper introduces a new haptic-supported software framework that facilitates the set up of different types of group interaction. The framework consists of multiple open source libraries supporting a range of external devices and services (e.g. Microsoft Kinect, cameras, Arduino controllers, sensors, AR tracking, remote haptic interaction,). To date three pilot studies have been conducted to test...
This paper reports the results of a pilot study evaluating the performance of healthy volunteers working in pairs to fulfil a collaborative task in both real and virtual environments. The main aim of this study is to investigate how different environments (real vs. virtual) and communication modalities (with vs. without talking to each other) affect the quality of interaction between humans. The results...
In this paper a new protocol for vibro-tactile robotic rehabilitation is proposed that combines the usage of vibrations with robotic movement assistance to augment rehabilitation outcomes for patients with spasticity. A simple protocol is proposed for focal vibration timing and position in respect to the muscle in order to accomplish the best muscle performance outcome. The results show an increase...
This paper reports the results of a pilot study with autistic children based on our recent work examining the potential of combining haptic and sonic exploration with a real painting as a tool for neurorehabilitation. The study consisted of seven children with autism exploring a painting enhanced with haptic and sound feedback. Audio-visual and kinematic data were collected to evaluate the participants'...
This paper examines a new form of interaction combining haptic and sonic exploration with static visual information from a real painting. Motivated by recent work in neurorehabilitation exploring group interactions with a robot, and by the educational and explorative value of artefacts, we investigate the feasibility of an interactive painting as a potential tool for the rehabilitation of brain injuries...
Robot-mediated therapies offer a new approach to neurorehabilitation. This paper analyses the Fugl-Meyer data from the Gentle/S project and finds that the two intervention phases (sling suspension and robot mediated therapy) have approximately equal value to the further recovery of chronic stroke subjects (on average 27 months post stroke). Both sling suspension and robot mediated interventions show...
