Pre-surgery evaluation, indications for cochlear implantation and expectations in terms of post-operative functional results remain challenging topics in pre-lingually deaf adults. Our study has the purpose of determining the benefits of Single Photon Emission Tomography (SPECT) assessment in pre-surgical evaluation of pre-lingually deaf adults who are candidates for cochlear implantation. In 7 pre-lingually profoundly deaf patients, brain SPECT was performed at baseline conditions and in bilateral simultaneous multi-frequency acoustic stimulation. Six sagittal tomograms of both temporal cortices were used for semi-quantitative analysis in each patient. Percentage increases in cortical perfusion resulting from auditory stimulation were calculated. The results showed an inter-hemispherical asymmetry of the activation extension and intensity in the stimulated temporal areas. Consistent with the obtained brain activation data, patients were implanted preferring the side that showed higher activation after acoustic stimulus. Considering the increment in auditory perception performances, it was possible to point out a relationship between cortical brain activity shown by SPECT and hearing performances, and, even more significant, a correlation between post-operative functional performances and the activation of the most medial part of the sagittal temporal tomograms, corresponding to medium-high frequencies. In light of these findings, we believe that brain SPECT could be considered in the evaluation of deaf patients candidate for cochlear implantation, and that it plays a major role in functional assessment of the auditory cortex of pre-lingually deaf subjects, even if further studies are necessary to conclusively establish its utility. Further developments of this technique are possible by using trans-tympanic electrical stimulation of the cochlear promontory, which could give the opportunity to study completely deaf patients, whose evaluation is objectively difficult with current audiological methods.La valutazione preoperatoria, le indicazioni all'impianto cocleare e le aspettative in termini di risultati funzionali post-operatorie rappresentano ancora problematiche di difficile soluzione nei pazienti adulti sordi pre-linguali. Lo scopo di questo lavoro è quello di verificare l'utilità della SPECT nella valutazione pre-operatoria di un gruppo di pazienti preverbali adulti candidati all'impianto cocleare. Sette sordi profondi preverbali sono stati sottoposti a SPECT cerebrale previa iniezione di 740 MBq di 99mTc-HMPAO in condizioni basali e di stimolazione acustica multi-frequenziale bilaterale e simultanea, con acquisizione di 6 tomogrammi sagittali per ambedue le cortecce temporali di ciascun paziente. I dati ottenuti hanno evidenziato una asimmetria interemisferica dell'estensione e dell'intensità di attivazione delle aree temporali stimolate. Un solo paziente ha mostrato una scarsa attivazione corticale dopo stimolazione acustica, che si è dimostrata del tutto coerente con i dati della valutazione clinica del soggetto, gravemente deficitario dal punto di vista uditivo e linguistico, mettendo in seri dubbi l'opportunità di eseguire l'impianto cocleare. Coerentemente con i dati di attivazione cerebrale ottenuti, gli altri pazienti sono stati impiantati prediligendo il lato che si attivava maggiormente in risposta allo stimolo acustico. Valutando il guadagno nelle prestazioni di percezione uditiva, si è potuto apprezzare una correlazione tra attività corticale dimostrata dalla SPECT e performance uditive, e tra performance funzionali post-operatorie ed attivazione dei tomogrammi temporali sagittali più mediali, corrispondenti alle medie-alte frequenze. Alla luce di queste considerazioni, noi riteniamo che la SPECT possa essere considerata nella valutazione dei pazienti ipoacusici candidati all'impianto cocleare, e che rivesta un ruolo di primaria importanza nella valutazione funzionale della corteccia uditiva dei pazienti preverbali, pur essendo necessari ulteriori studi per definirne l'effettiva utilità. Ulteriori sviluppi di questa tecnica si potranno avere con l'utilizzo della stimolazione elettrica trans-timpanica del promontorio, che potrebbe offrire così la possibilità di studiare anche i soggetti completamente sordi, la cui valutazione è difficoltosa con le metodiche audiologiche attuali.

- Abstract
Although the voice in a free field has an excellent recruitment by a cochlear implant (CI), the situation is different for music because it is a much more complex process, where perceiving the pitch discrimination becomes important to appreciate it. The aim of this study is to determine the music perception abilities among children with Cis and to verify the benefit of a training period for specific musical frequency discrimination. Our main goals were to prepare a computer tool for pitch discrimination training and to assess musical improvements. Ten children, aged between 5 and 12 years, with optimal phoneme recognition in quiet and with no disabilities associated with deafness, were selected to join the training. Each patient received, before training period, two types of exams: a pitch discrimination test, consisting of discovering if two notes were different or not; and a music test consisting of two identification tasks (melodic and full version) of one music-item among 5 popular childhood songs. After assessment, a music training software was designed and utilised individually at home for a period of six months. The results following complete training showed significantly higher performance in the task of frequency discrimination. After a proper musical training identification, frequency discrimination performance was significantly higher (p < 0.001). The same considerations can be made in the identification of the songs presented in their melodic (p = 0.0151) and full songs version (p = 0.0071). Cases where children did not reach the most difficult level may be due to insufficient time devoted to training (ideal time estimated at 2-3 hours per week). In conclusion, this study shows that is possible to assess musical enhancement and to achieve improvements in frequency discrimination, following pitch discrimination training.

The purpose of this study was to evaluate the benefits of unilateral cochlear implant (CI) in patients over 60 on speech perception and quality of life, comparing the results obtained with a control group of younger CI recipients. Twenty CI users (mean age 72 years), postlingually deafened, were included in this study. Audiological performance was evaluated using bisyllabic words and sentences recognition tests in a quiet and a noise environment. Moreover, we administered two questionnaires to evaluate the health status (SF-36), CI-related effects on daily activities and personal satisfaction (Questionnaire for self-evaluation of CI benefit with SADL scale modification). Performance measures of the geriatric population showed a significant benefit on speech recognition tests compared to pre-implantation condition, even if younger CI users scored significantly better in both bisyllabic words and sentences recognition test. All study patients reported being able to have a normal conversation with an acquaintance. No significant difference was found between the study and control group in physical and mental health status, conversation with an outsider, use of TV and phone. A significant difference ( p < 0.05) was noticed, instead, between elderly and younger adult patients about the overall satisfaction derived from CI. Our findings confirm the indisputable utility of CI and provide evidence that elderly patients derive a substantial benefit from it on quality of life, as demonstrated by health status, success in the common activities of daily living and perceived satisfaction after this procedure.

Platform ,Whole Body Vibration ,Acceleration measurement ,Characterization ,Modeling and Simulation ,Electrical and Electronic Engineering ,Vibration - Abstract
In the last decades, many studies have been conducted on the biological effects resulting from Whole-Body Vibration (WBV) platforms, even if benefits or side effects resulting from exposure to whole-body vibrations in sport and rehabilitation applications are often conflicting. These discrepancies are likely due also to different operating conditions such as load, unload, load position on footboard, etc. Since acceleration differences could affect the biological response of the person it would be suitable to verify the actual vibrations. Nevertheless a standard and widespread accepted method for measuring and verifying the actual vibrations provided by a WBV device has not been established yet. The authors performed a characterization of a novel WBV platform by developing a method reported in section II. The tests carried out in different conditions show that the footboard doesn’t provide quite uniform vibrations along the vertical direction over the platform. Furthermore, transversal accelerations have been detected and in some cases they reached the 25% of the vertical ones. Currently, very few studies have investigated whether a WBV platform produces comparable accelerations in at least two points of the footboard. This paper proposes a method for the characterization of WBV platforms and the comparison of their performances.

The Functional Reach Test (FRT) is a simple, portable, clinically accepted tool that is used to measure semi-static balance. In a recent study, video recordings and software elaborationshave beenperformed by a computerized system to determinethe FRT objectively (computerized FRT, cFRT):here an in-depthstudy on the measuring error of the above system is proposed.Main uncertainty sources identifiedare (a) geometrical errorsdue to the alignment of the camera calibration plane with the real motion plane, (b) the difference in depth between the above planes, (c) the image aberration due to the lens that compress the pixels and (d) the software error in position estimation using a template matching algorithm. The uncertainty evaluation is performed by means Monte CarloSimulationsand results suggest that both the depth error and the barrel distortion are the more relevant source of error, althoughthe aberration can be corrected by one of the many algorithms available in literature. Results can be useful to define a measurement protocol to improve the performances of thesystem for a better clinical effectiveness.

- Abstract
Background: Research on cooperative behavior and the social brain exists, but little research has focused on real-time motor cooperative behavior and its neural correlates. In this proof of concept study, we explored the conceptual notion of shared and complementary mental models through EEG mapping of two brains performing a real-world interactive motor task of increasing difficulty. We used the recently introduced participative "juggling paradigm," and collected neuro-physiological and psycho-social data. We were interested in analyzing the between-brains coupling during a dyadic juggling task, and in exploring the relationship between the motor task execution, the jugglers'skill level and the task difficulty. We also investigated how this relationship could be mirrored in the coupled functional organization of the interacting brains., Methods: To capture the neural schemas underlying the notion of shared and complementary mental models, we examined the functional connectivity patterns and hyperbrain features of a juggling dyad involved in cooperative motor tasks of increasing difficulty. Jugglers' cortical activity was measured using two synchronized 32-channel EEG systems during dyadic juggling performed with 3, 4, 5 and 6 balls. Individual and hyperbrain functional connections were quantified through coherence maps calculated across all electrode pairs in the theta and alpha bands (4-8 and 8-12 Hz). Graph metrics were used to typify the global topology and efficiency of the functional networks for the four difficulty levels in the theta and alpha bands., Results: Results indicated that, as task difficulty increased, the cortical functional organization of the more skilled juggler became progressively more segregated in both frequency bands, with a small-world organization in the theta band during easier tasks, indicative of a flow-like state in line with the neural efficiency hypothesis. Conversely, more integrated functional patterns were observed for the less skilled juggler in both frequency bands, possibly related to cognitive overload due to the difficulty of the task at hand (reinvestment hypothesis). At the hyperbrain level, a segregated functional organization involving areas of the visuo-attentional networks of both jugglers was observed in both frequency bands and for the easier task only., Discussion: These results suggest that cooperative juggling is supported by integrated activity of specialized cortical areas from both brains only during easier tasks, whereas it relies on individual skills, mirrored in uncorrelated individual brain activations, during more difficult tasks. These findings suggest that task difficulty and jugglers' personal skills may influence the features of the hyperbrain network in its shared/integrative and complementary/segregative tendencies., Competing Interests: Maurizio Bertollo and Silvia Comani are Academic Editors for PeerJ.

- Abstract
A novel system for the neuro-motor rehabilitation of upper limbs was validated in three sub-acute post-stroke patients. The system permits synchronized cortical and kinematic measures by integrating high-resolution EEG, passive robotic device and Virtual Reality. The brain functional re-organization was monitored in association with motor patterns replicating activities of daily living (ADL). Patients underwent 13 rehabilitation sessions. At sessions 1, 7 and 13, clinical tests were administered to assess the level of motor impairment, and EEG was recorded during rehabilitation task execution. For each session and rehabilitation task, four kinematic indices of motor performance were calculated and compared with the outcome of clinical tests. Functional source maps were obtained from EEG data and projected on the real patients' anatomy (MRI data). Laterality indices were calculated for hemispheric dominance assessment. All patients showed increased participation in the rehabilitation process. Cortical activation changes during recovery were detected in relation to different motor patterns, hence verifying the system's suitability to add quantitative measures of motor performance and neural recovery to classical tests. We conclude that this system seems a promising tool for novel robot-based rehabilitation paradigms tailored to individual needs and neuro-motor responses of the patients.

- Abstract
One post-stroke patient underwent neuro-motor rehabilitation of one upper limb with a novel system combining a passive robotic device, Virtual Reality training applications and high resolution electroencephalography (HR-EEG). The outcome of the clinical tests and the evaluation of the kinematic parameters recorded with the robotic device concurred to highlight an improved motor recovery of the impaired limb despite the age of the patient, his compromised motor function, and the start of rehabilitation at the 3rd week post stroke. The time frequency and functional source analysis of the HR-EEG signals permitted to quantify the functional changes occurring in the brain in association with the rehabilitation motor tasks, and to highlight the recovery of the neuro-motor function.

- Abstract
Conclusions: Despite the innovations in cochlear implant (CI) technology in recent years, some auditory tasks remain difficult for CI recipients. This work proposes the creation of specific maps for telephone communication (via conventional phone and via Internet protocol, VoIP). In light of our preliminary results, we believe that our experimental maps might improve conventional telephone and Internet communications for CI recipients., Objectives: This study aimed to: (1) analyze the spectro-temporal characteristics of the signals; (2) evaluate speech recognition scores using two different types of telephone communication; and (3) change some map parameters on the basis of the previous signal analysis, to obtain a specific map for telephone use., Methods: Eleven Cochlear™ Nucleus® CI recipients were tested for bisyllabic word recognition in quiet using reproduced voice and transmitted voice via conventional telephone and Skype® using the habitual-ACE (SLB) map, and two experimental maps (F- and V-Map)., Results: The results showed a worsening of word recognition scores with SLB-Map via telephone (30.5%) and VoIP (18.6%) compared with those achieved with the same map in an anechoic booth. In the experimental listening conditions, 65% and 54% of patients performed better with F- and V-Map, respectively, up to a maximum of performance improvement by 35% via telephone and 25% via VoIP.

- Abstract
MRI is a widespread and greatly helpful diagnostic tool, yet its use on cochlear implant patients is restricted by the presence of an inner magnet. We report on a case of magnet dislodgment after 1.5T MRI in a 31-year-old female with a Hi-Res 90K cochlear implant. In this case, it was possible to implement an alternative, totally noninvasive approach based on an external manual repositioning rather than a surgical procedure of the displaced magnet., (Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.)
