Background and Aims
Early identification of nerve lesions and associated neuropathic pain in spine-related pain disorders is important for tailored treatment. Management may consist of surgical intervention for compressive neural lesions.
With a growing waitlist for public surgical outpatient clinics in Western Australia and wait times exceeding the recommended wait time for initial assessment (Category 1 – assessment within 1 months, Category 2 within 3 months, category 3 within 12 months), a call to support new models of care has been made1, including the evaluation and expansion of workforce models supporting advanced skills in allied health.1
An Advanced Scope Physiotherapy (ASP) led Neurosurgery Spinal Clinic operates at Sir Charles Gairdner Hospital in Western Australia. The ASPs (2FTE) examine patients from the neurosurgery waitlist for their suitability for spinal surgery. Recommendation of either further investigation and possible assessment by a neurosurgeon or appropriate non-surgical management of the patients’ pain condition is suggested. Patient assessment is conducted either ‘in person’ at the hospital or via telehealth due to the remoteness of some rural patients. Patient cases are discussed with a neurosurgery consultant on a weekly basis. The aim of this project is to evaluate the ASP service in the year 2022.
Method
A retrospective descriptive analysis of patient data captured in 2022 was performed.
Results
In 2022, 1337 new patient referrals were managed plus 267 follow-ups from the previous year. Category 1 patients (n=81) waited on average 31 days for their first appointment, Category 2 patients (n=394) waited 76 days and Category 3 patients (n=854) waited 376 days.
287 (18%) referrals were discharged without physical assessment of the patient (DNA, cancellations, declined). Of the 1317 patients physically assessed by the ASPs (57%) were discharged directly after assessment, for 290 patients (22%) their outcome was still pending at time of analysis (March 2023) and 281 (22%) patients were referred for review with a neurosurgeon. Of the 229 patients assessed by a neurosurgeon (including patients from 2022), 103 patients (45%) were offered surgery, 52 (23%) were not offered surgery, 46 ( 20%) patients had to be reviewed, and for the remaining (n=18) their outcome was unknown.
Conclusion
Of the 1604 patients managed in the Neurosurgery Spinal Clinic, only 17% needed to see a neurosurgeon. The conversion rate to surgery of 45% is higher compared to an estimated 5%-10% in a non-triaged clinic.
The ASP model of care has proved invaluable to (i) provide access of patient care within the recommended wait times (ii) optimize neurosurgeons’ time, (iii) educate patients and, in case of non-suitability for surgery, advise and refer them for alternative appropriate management.
Relevance for Patient Care
The Advanced Scope Physiotherapy model of care at the Neurosurgery Spinal Clinic allows timely assessment of patients with spine-related disorders and supports targeted management of their condition.

Workshop: “‘Sciatica’: neuropathic or not and does it matter? Outcomes from a NeuPSIG working group”
(2023)
The identification of neuropathic pain in persons with spine-related leg pain is important as this information guides treatment and management, including self-management. The NeuPSIG neuropathic pain grading system was developed to assist clinicians and researchers in determining whether patients have neuropathic pain and the level of confidence associated with that decision. Based on clinical and laboratory examination findings, patients are classified as having no neuropathic pain, possible, probable or definite neuropathic pain. Whereas this grading system works nicely in people with systemic neuropathies where sensory findings and diagnostic tests are mostly present, its application in patients with spine-related leg pain, particular in radicular pain, can be challenging. For example, in the absence of sensory changes and MRI findings, patients with radicular pain would at best reach a classification of possible neuropathic pain according to the current neuropathic pain grading system.
In this presentation I will explain the adaptations to the neuropathic pain grading system for spine-related leg pain recommended by the NeuPSIG working group. I will demonstrate its application in clinical practice using case studies and provide clarity for how the system can be incorporated in clinical trials. This will be an interactive session with audience participation.
Das Ziel der vorliegenden Ausarbeitung ist es darzustellen, welchen psychosozialen Belastungen Väter frühgeborener Kinder während der Zeit der kindlichen Hospitalisierung auf der Neonatologie ausgesetzt sind und welcher Auftrag sich dadurch für die Soziale Arbeit in diesem Praxisfeld ergibt. Dazu wird die Forschungsfrage gestellt: „Welchen psychosozialen Belastungen sind Väter von frühgeborenen Kindern während des kindlichen Aufenthaltes auf der Neonatologie ausgesetzt?“. Für das Forschungsvorhaben wurde eine quantitative Studie im Querschnittdesign mit der Zielgruppe von Vätern frühgeborener Kinder durchgeführt. Die Ergebnisse der Erhebung zeigen, dass besonders die Aufteilung zwischen innerklinischen sowie außerklinischen Verantwortungen und die fehlende Ausübung von Väterrollen die größten Belastungen darstellen. Die Väter zeigen zudem mehrheitlich Symptome einer Belastungsstörung. Gesprächen mit Partner*innen oder Familienangehörigen werden am häufigsten eine entlastende Wirkung zugeschrieben. Insgesamt zeigt sich, dass die Mehrheit der befragten Väter an keiner Elternberatung teilgenommen hat. Jedoch wünscht sich die breite Mehrheit aller befragten Väter explizite Angebote der Elternberatung für Väter frühgeborener Kinder. Aus den Ergebnissen ergibt sich für die Soziale Arbeit ein Auftrag, für die Belange und Bedürfnisse von Vätern frühgeborener Kinder auf der gesellschaftspolitischen Ebene und im Netzwerk einzustehen sowie die Elternberatung in der Neonatologie durch qualifizierte Weiterbildung und organisatorische Umstrukturierung zielgruppenfreundlich auszurichten.
Purpose
Sedentary behaviour (SED) and low level of physical activity (PA) might be associated with the development or worsening of pain. Still, studies assessing physical behaviours by accelerometry in individuals with orofacial pain are limited. This study aims to assess whether women with temporomandibular disorders (TMD) present different patterns of physical behaviours in days with (DWP) or without pain (DWoP).
Methods
Twenty-nine out of forty-four women (mean age 29.21 sd 7.96) were diagnosed with TMD and monitored over seven days using a thigh-worn accelerometer. DWP was determined when subjects presented pain in one of the craniocervical regions (head, jaw and neck) with intensity of at least 3 in the numerical rating scale. To be considered a DWoP, the individual presented less than 3 points in the three regions. Daily time-use compositions were described in terms of SED in short (<30 min) and long (≥30 min) bouts, light PA (LPA), moderate-to-vigorous PA (MVPA), and time-in-bed. Isometric log-ratios (ilr) were calculated to express the ratio of time-in-bed to time spent awake, SED relative to LPA and MVPA, SED in short relative to long bouts, and LPA relative to MVPA. Differences between DWP and DWoP were examined using MANOVA, followed by univariate post-hoc tests of pairwise differences.
Results
During DWP, women with TMD spent more time in SED in short (239 min) and long bouts (419 min), less time in LPA (245 min), MVPA (68 min), and in bed (468 min) compared with DWoP (235, 378, 263, 70 and 493 min, respectively). The MANOVA showed that all sets of ilrs did not differ statistically (ηp2 = 0.19, p = 0.25). Still, the post-hoc tests showed a trend that time spent SED relative to LPA and MVPA was larger in DWP than in DWoP (Cohen’s d = 0.36, p = 0.05).
Conclusions
Women with TMD did not show different patterns of physical behaviours in DWP or DWoP. However, there is a trend of more sedentary behaviour and less physical activity in DWP compared to DWoP. Future studies should consider other pain intensity cut-offs, isolated pain locations, and larger sample sizes to confirm these results.
Nostalgia is a construct that, even when rooted in lived experiences, serves the ultimate purpose of creating a desired sense of world. Fundamental cognitive competencies, including memory and imagination, are utilized by the nostalgic subject to fulfill a need for narrative coherence. A temporal or spatial distance is necessary for the occurrence of a nostalgic episode, which can be conceptualized as a “had been” state of being, as direct access to the experience is often impossible. Nostalgia may thus be viewed as a tool for sense-making rather than solely as a yearning for the past. The nostalgic narrative form is a construct that permits human subjects to comprehend their existence in the world while drawing upon their roots. These tools for sense-making serve as bridges between past experiences and current conditions. Ultimately, nostalgic identity is not just about longing for the past but also about utilizing the past as a resource for navigating the labyrinths of the present. Analyses are conducted to examine the medium of music video at three levels - auditory, visual, and linguistic - in order to investigate the strategies and techniques employed by the Iranian diaspora to create nostalgic narratives. Samples of original pieces and renditions are contrasted in order to identify elements of nostalgic narrativity. Drawing on empirical research, it is argued that the unity of a music video arises from the integration of separate layers of sensory and conceptual inputs that have been composed towards an affective resonance and narrative coherence.
Background: Multilingual children with suspected SLCN are often overlooked or their needs not accurately differentiated regarding the necessity of language support or therapy. The purpose of the study was to conceptualize, carry out and evaluate a local language support (LS) project within linguistically and culturally diverse (LCD) families and its effects on all collaborating participants.
Methods: Eight SLT students and one lecturer took part in the LS-project, alongside equivalent numbers of family liaison personnel. Students visited more than 10 young children aged between 2-6 years, and for each child 10 weekly home visits were carried out. Language enhancement was documented, several case studies with children and interviews with five liaison personnel conducted.
Results: All SLT students perceived changes in the behaviour and communication of participating children. Children in the case studies developed from pre-verbal to verbal means of communication and family liaison personnel reported positive changes alongside parental wishes to continue the support.
Conclusion: Local language support projects with LCD families can lead to positive differences regarding their children's communication development and better inclusion in mainstream society. SLT students benefit from working with LCD families and their collaborative support together with family liaison personnel, and vice versa.
Learning Outcomes: To differentiate the influence of language enhancement vs. formalized SLT therapy. To enhance the relationship with LCD clientele and collaboration with liaison personnel in SLCN settings. To incorporate life-long learning and intercultural sensitization.
In modern times, closed-loop control systems (CLCSs) play a prominent role in a wide application range, from production machinery via automated vehicles to robots. CLCSs actively manipulate the actual values of a process to match predetermined setpoints, typically in real time and with remarkable precision. However, the development, modeling, tuning, and optimization of CLCSs barely exploit the potential of artificial intelligence (AI). This paper explores novel opportunities and research directions in CLCS engineering, presenting potential designs and methodologies incorporating AI. Combining these opportunities and directions makes it evident that employing AI in developing and implementing CLCSs is indeed feasible. Integrating AI into CLCS development or AI directly within CLCSs can lead to a significant improvement in stakeholder confidence. Integrating AI in CLCSs raises the question: How can AI in CLCSs be trusted so that its promising capabilities can be used safely? One does not trust AI in CLCSs due to its unknowable nature caused by its extensive set of parameters that defy complete testing. Consequently, developers working on AI-based CLCSs must be able to rate the impact of the trainable parameters on the system accurately. By following this path, this paper highlights two key aspects as essential research directions towards safe AI-based CLCSs: (I) the identification and elimination of unproductive layers in artificial neural networks (ANNs) for reducing the number of trainable parameters without influencing the overall outcome, and (II) the utilization of the solution space of an ANN to define the safety-critical scenarios of an AI-based CLCS.
Stainless steel made to rust: a robust water-splitting catalyst with benchmark characteristics
(2015)
The oxygen evolution reaction (OER) is known as the efficiency-limiting step for the electrochemical cleavage of water mainly due to the large overpotentials commonly used materials on the anode side cause. Since Ni–Fe oxides reduce overpotentials occurring in the OER dramatically they are regarded as anode materials of choice for the electrocatalytically driven water-splitting reaction. We herewith show that a straightforward surface modification carried out with AISI 304, a general purpose austenitic stainless steel, very likely, based upon a dissolution mechanism, to result in the formation of an ultra-thin layer consisting of Ni, Fe oxide with a purity >99%. The Ni enriched thin layer firmly attached to the steel substrate is responsible for the unusual highly efficient anodic conversion of water into oxygen as demonstrated by the low overpotential of 212 mV at 12 mA cm−2 current density in 1 M KOH, 269.2 mV at 10 mA cm−2 current density in 0.1 M KOH respectively. The Ni, Fe-oxide layer formed on the steel creates a stable outer sphere, and the surface oxidized steel samples proved to be inert against longer operating times (>150 ks) in alkaline medium. In addition Faradaic efficiency measurements performed through chronopotentiometry revealed a charge to oxygen conversion close to 100%, thus underpinning the conclusion that no “inner oxidation” based on further oxidation of the metal matrix below the oxide layer occurs. These key figures achieved with an almost unrivalled-inexpensive and unrivalled-accessible material, are among the best ever presented activity characteristics for the anodic water-splitting reaction at pH 13.
