“…This study arose from a larger randomized controlled cross-over design clinical trial that explored patient’s perceptions of two indwelling voice prosthesis systems: the Provox Vega Indwelling voice prosthesis (Atos Medical) and the Blom–Singer Classic Indwelling voice prosthesis (Inhealth) as reported elsewhere [27, 28]. These participants were recruited from the speech pathology outpatient files of the Princess Alexandra Hospital, Queensland, Australia.…”

Device life of the Provox Vega Indwelling voice prosthesis is as yet untested outside Europe. The current study examined device life and reasons for replacement within an Australian clinical setting. Twenty-three participants were monitored for device life and reasons for replacement. Main outcome measure was days to failure of initial device. Average device life and reasons for replacement were secondary measures. Initial device life data revealed 67 % had functioning devices at 3 months, 52 % at 6 months and 29 % at 12 months. Average device life was 207 days (median of 222). The majority of devices (97 %) failed due to leakage through the prosthesis. The Provox Vega Indwelling voice prosthesis had favourable device life in this cohort of patients and in comparison to European data. Reasons for replacement were consistent with international literature.

“…In the original study [27, 28] participants trialed both devices for a 3-week period with the order of device trial randomly allocated. The short-term component was intended to gain patient perceptions of voice effort and quality, insertion and care of devices as well as perceptual judgment of voice quality by both participants and listeners.…”

“…However, despite the fact that numerous different devices exist, to date there has been limited systematic research directly comparing different indwelling devices and the patients’ perceptions of them. In the few published studies available, the primary focus has been to compare voice quality (perceptual and acoustic) (Delsupehe et al 1998, Hilgers et al 2010a, Ward et al 2011) as well as device life and overall satisfaction (Delsupehe et al 1998). What has not been examined in detail, however, is whether patients perceive differences between different indwelling prostheses across other aspects of device function, such as other physical factors associated with the use of a voice prosthesis (e.g., air ingestion/bloating, inadvertent valve opening, leakage), the insertion process, and cleaning and maintenance.…”

“…The first results with the Provox Vega voice prosthesis and SmartInserter demonstrated good clinical feasibility (Hilgers et al 2010a, 2010b). When compared with the Blom–Singer Classic, device, improved voice and speech outcomes have been reported for the Provox Vega (Ward et al 2011). However, as yet there has been no systematic exploration of patient perceptions about aspects of device beyond voicing and their impact on patient choice.…”

Background: Technical and device life issues are frequently the focus of post‐laryngectomy rehabilitation studies examining indwelling voice prostheses. Patient perceptions and preferences are considered less often. Aims: To determine patient perceptions of two indwelling voice prostheses across parameters relating to device use and maintenance and to determine what factors contribute to patient preferences. Methods & Procedures: In a randomized, cross‐over study, 31 laryngectomy patients completed a 3‐week trial of both the new indwelling Provox Vega and a comparator device, the Blom–Singer Classic Indwelling. Patient perceptions of the insertion process, cleaning and care, and voicing were explored after each trial. At the end, overall preference and factors influencing device preference were examined. Outcome & Results: At the conclusion of the crossover trial, a significantly higher proportion of patients felt voice effort, overall voicing, bloating, and ease and effectiveness of cleaning were superior for the Provox Vega. No preference was noted for insertion processes. Overall device preference was influenced by improved voicing followed by cleaning and care. Conclusions & Implications: Patients do not perceive all indwelling devices as equal and should have the opportunity to trial different devices to find the best device for their needs.

Abstract-Brain-Computer Interfacing (BCI) enables a communication pathway that is used to directly control certain object or device with the human brain. It is possible to acquire data from the brain with the help of sensors which essentially monitor the physical processes that occur in the brain and with the help of software we can direct a device accordingly. BCI introduces its users a new system that communicates in a special way without the use of muscles. BCI also provides a useful platform for the people with physical disabilities to conveniently perform certain tasks in our society. It uses brain imaging technologies which help in increasing the quality of the communication between humans and machines. There has been significant research effort in the past decade to explore different aspects of this promising field of technology. Previously, BCIs had limited functionality but due to recent advancement in technology it has attained the maturity of its own right by adding new trends and extra features to it.In this paper, research work of development and integration of both hardware and software in BCI and the advancements of BCI are surveyed considering all the possibilities of direct communication of computers with a brain using emerging technologies. Different approaches used up till now with an overview of the methodology are presented to make the reader understand its meaning and functionality in a compact way. This research paper will guide a beginner to end up with a thorough knowledge of what's, how's and why's of BCI. In addition, BCI applications, challenges, possible solutions and future directions have also been discussed.
