Speech-language pathologists generally agree that cluttering and stuttering represent two different fluency disorders. Differential diagnostics between cluttering and stuttering is difficult because these disorders have similar characteristics and often occur in conjunction with each other. This paper presents an analysis of the differential diagnostic characteristics of the two disorders, and a proposal for distinguishing between the two in clinical settings. The main goal of this two-part article is to set objective norms for differential diagnostic assessment of cluttering and stuttering symptoms, based on the three main characteristics of cluttering indicated/identified by St. Louis, Raphael, Myers & Bakker [St. Louis, K. O., Raphael, L. J., Myers, F. L., & Bakker, K. (2003). Cluttering updated. The ASHA leader. ASHA, 4–5, 20–22]: a fast and/or irregular articulatory rate together with errors in syllable, word or sentence structure and or a high frequency of normal disfluencies (not being stuttering). In the first half of the article objective measures are compared to the subjective clinical judgement made by fluency experts. In other words, which characteristics can be found in the speech profiles of persons who were diagnosed as people who clutter or stutter? In the second part of the article results on the Predictive Cluttering Inventory [Daly, D. A., & Cantrell, R. P. (2006). Cluttering characteristics identified as diagnostically significant by 60 fluency experts. Proceedings of second world congress on fluency disorders] are discussed in relationship to the subjective and objective measurements studied in the first half of the article.
This article presents a variety of treatment approaches based on an understanding of four components of communication, and describes cluttering intervention focusing on problem identification, speech rate reduction, appropriate pausing, appropriate monitoring, and addressing story narrating skills. Therapeutic considerations, taking into account the specific characteristics of cluttering, will also be presented. Finally, building clients’ confidence, emotional skills, and sense of accomplishment will turn the therapeutic process into awareness of realistic expectations and motivation to pursue challenging goals. Cluttering is a disorder of speech fluency in which people are not capable of adequately adjusting their speech rate to the syntactical or phonological demands of the moment (van Zaalen, 2009). When language production is relatively easy, people with cluttering (PWC) are capable of producing fluent and intelligible speech. When language production demands are more complex, the speech rate should be adjusted to the language complexity. PWC tend to have difficulties doing so. This reduced ability of PWC to control their speech rate results in either a higher than normal frequency of disfluencies or multiple speech errors. This article presents various intervention approaches based on an understanding of four components of communication: cognitive, emotional, verbal-motor, and communicative. The article focuses on problem identification, speech rate reduction, appropriate pausing, and addressing monitoring and story narrating skills. Therapeutic considerations, taking into account the specific characteristics of cluttering, will also be presented.

MSEs have encountered limitations while pushing the limits of catheter tip sensors performance. The limitations summarized: - sensors are not immune to electrical signal noise, cross talk, and EM fields; - sensors are not immune to high magnetic fields, i.e. not suitable for MR imaging; - extending the amount of sensors on the catheter tip is limited due to cluttering of wires. A fundamentally different approach using integrated optics is chosen for developing a new generation catheter sensors. The complexity of the design and production problems represents a knowledge gap, that can be bridged in the proposed consortium. This project consists of four work packages, total duration two years, subdivided into four phases. A crucial deliverable of the project is presented at the end of phase IV (WP4), namely a demonstrator integrating pressure and temperature sensors (obtained from WP1) with a newly designed readout system. This system is modularly extendable for future catheter tip sensors. In WP1, pressure- and temperature sensors are developed using two design approaches. In WP2 the influence of downscaling an ultrasound MZI device is explored and the microfabrication process parameters are studied. An additional goal of WP2 is to find the most suitable method for measuring lactate concentration. Among the deliverables five manuscripts: manuscript 1 includes simulations and measurements of the developed pressure and temperature sensors, manuscript 2 answers the question: can a grated fiber be used for measuring pressure and temperature on a tip? Manuscript 3 answers the question: which method is most suitable for measuring lactate concentration on a tip? Manuscript 4 answers the question: does a US intensity detector fit on a catheter tip while obeying the LoR? Manuscript 5 describes the performance of the demonstrator (Phase IV), i.e. integration of T/P sensing with a modular read out system.
