Introduction/Background Neurogenic bladder dysfunction is one of the most important sequelae after spinal cord injury, stroke or multiple sclerosis Intermittent catheterization (IC) is an effective bladder management strategy for incomplete bladder emptying However, the patients with impaired hand function are difficult to perform self IC and dependent to caregivers Thus, we developed a new small-sized portable device for self catheterization. Material and method The new device is composed of two parts; disposable part and operating part The disposable part would be consist of a penis cap which would contact with glens of penis and contain lubricational system, and a sterilized catheter The operating part would include a gear and motor which would advance the catheter, and a rechargeable battery. The penis cap of disposable part would be docked with operating part Then the operating part would advance the catheter into the penis cap and orifice of the penis This system would be composed of sponge containing distilled water As the pre-lubricated hydrophilic catheter used in this system would contact with the sponge, the catheter could be lubricated and glide smoothly into the penis. Results In a dummy model phantom study, the catheter was lubricated well and inserted smoothly into the bladder without any complications We filed a patent for a new device lubrication system. Conclusion We confirmed a possibility of the newly developed portable automatic urinary catheterization device that could assist performing the IC Even a patient with impaired fine motor ability in upper extremity or a caregiver might perform the IC easily using this device.

Introduction/Background Rehabilitation patient activity is not typically monitored in real-time due to lack of suitable actigraphy devices. We present an open-source actigraphy system with integrated real-time cloud data storage based on mobile phones for potential use in patient activity monitoring and quantitation. Material and method An iPhone program was created to stream an actigraphy score to a cloud data storage service, Adafruit IO, in real-time. The actigraphy score is calculated as vector magnitude from three-axis accelerometer data at 2.5 second epochs. Results Actigraphy data was successfully streamed to the cloud storage and visualization platform at up to 30 Hertz, with 60 Hertz possible at a higher cost tier. Data was represented as decimal with two significant digits of precision. No movement at all is normalized to 0. Maximum vector magnitude with moderate walking was
e499
0.39. Maximum vector magnitude with jogging was 1.02 Maximum vector magnitude with the phone in the hand during a throwing motion was 5.47. iOS reported energy draw was low (level 1 out of 20). Conclusion In summary, we present an open-source design for a simple and inexpensive real-time cloud-connected actigraphy system for rehabilitation patients. Alternative platforms and devices are discussed, as are security and cost implications The widespread use of mobile devices and the iOS platform, with optional integration of global positioning coordinates and other phone data, are advantageous compared to purpose-built existing actigraphy solutions.

E-mail address: [email protected] (R. Feingold Polak) Introduction/Background The number of seniors in the world is growing and it is expected that there will be a growing need for home and nursing care services For this purpose, robots are expected to perform tasks of providing personal assistance and social care for the elderly Socially assistive robots (SAR) are a natural category for this endeavor In order for robots to be effective assistive tools, they must be accepted by the intended user population. Aims To test how age, location of touch interaction, and embodied presence of a humanoid robot affect the preferences of different age-group users when performing a cognitive-motor task Material and method A total of 60 subjects participated in two experiments The participants played a memory game of reach to grasp task using real physical cups with an SAR In the first experiment, 10 young (24.6 ± 2.6) and 10 older adults (70.8 ± 5.7) played 12 trials of the game with the robot In the second experiment, 20 young (24.75 ± 2.2) and 20 older adults (69.4 ± 5.64) randomly played 10 trials with the robot and 10 trials with a computer screen When finished, they completed a questionnaire. Results In both experiments participants preferred real humanlike interaction with an SAR (In experiment 1: 70% P = 0.115; In experiment 2: P = 0.008 for petting the hand vs touching the tablet, P = 0.0022 in the older group), as they found it more “human-like” and “intimate” We found a significant preference for interacting with a robot over a screen (P < 0.001) This preference was stronger in the young group (P < 0.0001, vs P = 0.157 in the older group) Participants mentioned the robot was more “engaging”, “interesting” and “human-like”. Conclusion Both age groups preferred the interaction with a robot over a screen and specifically, real human-like interaction with a robot. The preferences of different populations, i.e. stroke, will be investigated in a future study.
