Title: The effect of symptoms of depression on foot self-care practices and diabetes-related knowledge in housebound people with diabetes mellitus Abstract: Aim: To investigate the effect of symptoms of depression on both foot self- care practices and diabetes related knowledge in housebound people with diabetes. Methods: A prospective quasi-experimental design was employed, and participants were recruited from the Active Aging and Community Care database and conducted at their own homes. The sample population was divided into two groups following the SRQ-20: Group 1: 55 housebound participants with diabetes and without symptoms of depression and Group 2: 62 housebound participants with diabetes and with symptoms of depression. Participants were recruited through convenience sampling by the intermediaries. The intermediaries contacted the participants by telephone and upon verbal consent to the intermediaries, the researcher conducted the house visits and recruitment. Four questionnaires were utilised: The Self- Reporting Questionnaire (SRQ-20) (To assign into the respective group), the Diabetes Knowledge Questionnaire (DKQ-24) (To assess the knowledge), Nottingham Assessment of Functional Feet (NAFF) (To assess foot care behaviour) and EQ-5D-5L Questionnaire (To assess Quality of Life). Participants were assessed at three time points over six months, with changes in diabetes knowledge, foot care behaviours, and quality of life assessed and recorded. Results: Of the 124 participants who initially agreed, 117 were included in the analysis; 7 were excluded, due to admission to long-term care (n=3) and voluntary withdrawal (n=4). Both the Kolmogorov-Smirnov and Shapiro-Wilk tests were conducted to test for normality for both the DKQ-24 and NAFF Questionnaire separately and non-parametric test were used. The mean DKQ-24 scores increased significantly over time in both groups (p < 0.001), with no significant differences between participants with and without symptoms of depression at any time point (p > 0.05), indicating similar improvements in diabetes-related knowledge. The mean NAFF scores also increased significantly over time in both groups (p < 0.001), with participants without symptoms of depression consistently scoring higher than those with symptoms at all time points (p < 0.05), reflecting better foot self-care behaviours. These findings suggest that while symptoms of depression did not affect knowledge acquisition, it was associated with lower engagement in foot self-care practices. [...] Description: M.Sc.(Melit.)

Title: A comparison between the 12-lead electrocardiogram and hand-held spectral waveform doppler ultrasound in the detection of atrial fibrillation (Master's dissertation). Abstract: Background: Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and a leading cause of thromboembolic stroke. Early detection is essential to initiate timely intervention and reduce associated morbidity and mortality. While electrocardiography (ECG) remains the gold standard for AF diagnosis, its routine use in community settings is limited. Pedal Doppler ultrasound (US) is already widely utilised in podiatric practice for vascular assessments, offering a potential opportunity for opportunistic AF screening during routine foot care. However, evidence quantifying the accuracy of pedal Doppler US for arrhythmia detection is limited. Aim: This study aimed to evaluate the accuracy of pedal Doppler US in identifying atrial fibrillation when compared with ECG findings, to determine its potential role as an opportunistic screening tool within podiatric practice. Methods: A cross-sectional study was conducted involving 112 participants aged 65 years and older. Pedal Doppler US was used to classify peripheral pulse patterns as regular, partially regular, or irregular. ECG served as the reference standard to confirm the presence or absence of arrhythmias. Chi-square analysis was employed to assess the association between Doppler findings and ECG results, and Cramér’s V was calculated to estimate effect size. Results: A strong, statistically significant association was found between Doppler-detected irregular pulses and ECG-confirmed arrhythmias (χ²(1, N=112)=52.42, p<0.001, Cramér’s V=0.68). Doppler US reliably identified all cases of irregularly irregular rhythms indicative of AF but failed to detect regular arrhythmias such as first-degree atrioventricular block and sinus bradycardia. Conclusion: Pedal Doppler US shows considerable promise as a rapid, non-invasive, and accessible preliminary screening tool for irregular arrhythmias in podiatric settings. With appropriate training to standardize interpretation, podiatrists could play a pivotal role in opportunistic AF detection, facilitating timely ECG referral and potentially reducing stroke incidence in at-risk populations. Larger-scale, multi-center studies are recommended to validate these findings and inform future clinical guidelines. Description: M.Sc.(Melit.)

The evolving field of mobile applications : a smarter approach to diabetic foot ulcer measurement

Title: The evolving field of mobile applications : a smarter approach to diabetic foot ulcer measurement Abstract: Aim: This study evaluates the inter-rater reliability of diabetic foot ulcer (DFU) measurement using the traditional paper-ruler method versus the Imito Wound Application. Given the clinical importance of accurate and reproducible ulcer measurement, the research aims to determine whether a smartphone-based application offers a more reliable alternative to standard care, thereby improving DFU prognosis and management. Research Design and Method: A comparative observational study was conducted involving clinicians measuring DFUs using both the paper-ruler method and the Imito Wound App. A total of 67 DFUs were assessed, with each ulcer measured independently by three raters using both methods. The inter-rater reliability was analyzed using intraclass correlation coefficients (ICC), and statistical assessments were performed using SPSS software. Additional analyses considered the impact of ulcer shape and location on measurement reliability. Results: The results have highlighted that measurements performed by the ruler method have a difference by 1.43 times across all raters when compared to the Imito Application results. The ICC of both measurements was very good, with Imito App having a slightly better interrater reliability that of ICC- 0.975 vs ICC of 0.970 for the Ruler measurements. Ulcer shape and location influenced reliability, with irregularly-shaped DFUs exhibiting greater measurement discrepancies in the ruler method. Conclusion: The findings underscore the limitations of the paper-ruler method and support the use of smartphone-based wound measurement tools for DFU assessment. The Imito Wound App significantly enhances measurement reliability, reducing inconsistencies that could impact treatment decisions by the introduction of a more objective measuring tool. Integrating digital wound measurement into clinical practice could improve DFU monitoring, ultimately reducing the risk of complications and lower limb amputations. Description: M.Sc.(Melit.)

An investigation into remodelling, morphological and mechanical changes in the clinical management of mid-portion achilles tendinopathy

Title: An investigation into remodelling, morphological and mechanical changes in the clinical management of mid-portion achilles tendinopathy Abstract: Mid-portion Achilles tendinopathy is a chronic degenerative tendon condition characterised by pain, impaired function and structural alterations that compromise tendon integrity, affecting both sedentary and active individuals. Despite its widely reported high prevalence, the remodelling process during treatment remains poorly understood. This research investigates Achilles tendon remodelling during rehabilitation and High-Volume Image Guided Injection treatment, focusing on mechanical and morphological property changes to improve clinical management and patient outcomes. Carried out in three phases, the research first identified gaps in clinical practice and assessment modalities through various reviews and a sequential mixed methods scoping study. The findings highlighted the insufficiency of relying solely on morphological evaluation and underscored the local needs for optimised referral pathways, objective outcome measures and multidisciplinary care integration. This led to the establishment of a multidisciplinary Sports and Exercise Clinic. In phase two, the research validated both shear wave elastography and myotonometry as methods for measuring small tendon strains, the latter emerging as the more pragmatic tool. This led to the development of a standardised reliability protocol for consistent monitoring of tendon mechanical properties during treatment and rehabilitation. Phase three employed a pragmatic, assessor-blinded randomised controlled trial comparing exercise rehabilitation alone to High-Volume Image Guided Injection combined with exercise. The findings suggest that although both groups achieved comparable pain reduction, the intervention group showed an early unexpected reduction in stiffness (t=-3.09(16), p=0.007), raising questions about the injection’s immediate mechanical effect on the tendon. Furthermore, tendon bulge thickness decreased significantly in the intervention group, though this change fell short of clinical significance suggesting that morphological changes may require longer period to manifest. These findings should be interpreted in light of the small sample size, which was justified by a higher prevalence of insertional tendinopathy (67.9%) compared to mid-portion tendinopathy (20.3%) in the study population - an observation linked to shorter free tendon length, which may represent a potential anatomical risk factor for insertional tendinopathy. This research provides novel insights into tendon remodelling and is the first to objectively quantify short-term mechanical stiffness post High-Volume Image Guided Injection, highlighting a previously underexplored aspect of treatment efficacy and underscoring the need for further studies to evaluate the injection’s long term biomechanical impact.
