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.)

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.

Telemedicine benefits accessibility to health care services and promotes the quality of healthcare and organizational efficiency. Nonetheless, there are significant barriers to standardizing telemedicine as well as its complete consolidation and expansion. Although a growing number of pilot projects and viability studies have been carried out in various healthcare professions, only a few telemedicine applications have been rooted in clinical practice and consolidated into medical processes. Moreover, even these were frequently dropped once the initial phase was over due to heavy regulatory laws and resistance to change from stakeholders. This PhD research study aimed to investigate the feasibility of the development of a podiatric telemedicine framework for low-risk patients in a primary care setting. This research evaluated the possibility of implementing telemedicine in core podiatry; analyse interactions that arise throughout the process of implementation in podiatric care and changes that occur in organizations, management models, culture, and healthcare services. It also reflects on significant features associated to prioritization, design, deployment, integration, and assessment tailored for core podiatry services. The evaluation of the developed podiatric telemedicine guideline ultimately concentrates on significant aspects in the successful development of telemedicine and generates recommendations to overcome difficulties that could arise. This research comprised three main studies, an initial scoping study to investigate current foot and ankle telemedicine practice guidelines, the second study adopting a modified Delphi 3 study to develop the podiatric telemedicine guideline, followed by the last phase which included healthcare provider training and a pilot study testing the podiatric telemedicine guideline in a primary care setting. Lastly, this PhD research shed light on the challenges faced and opportunities for podiatric service expansion in a primary care setting. This study developed the first evidence-based guideline for podiatry services in a primary care setting for low-risk patients. Description: Ph.D.(Melit.)

With a high global prevalence, especially in older adults and females, HAV lacks a consensus on an effective form of conservative treatment, and many acute and chronic situations of HAV involved surgery as the conventional treatment. Surgery in itself can create complications and risk for the patient, therefore the justification of an effective non-invasive treatment approach is both clinically and cost effective. The aim of this PhD study was to explore, assess, and test an innovative non-invasive therapeutic device; an ergonomically designed Hallux Valgus (HV) sock with a biomechanical corrective effect to relieve symptoms and restore function. The study was undertaken in four phases. Phase I entailed a full systematic review of non-surgical treatments for HAV. The systematic review involved determining clinical effectiveness, methodological quality, and biomechanical rationale of various interventions, including orthotic devices, physical therapy, footwear modifications, and bracing methods. It also aimed to assess the long-term outcomes and potential risks associated with each treatment modality, providing a comprehensive analysis of their effectiveness in halting or reversing the progression of hallux valgus.. The review found no close similarity across studies, substantial variability in outcomes, and limited high-quality evidence showing long term effectiveness for non-surgical approaches – signifying a clinical need to develop and conduct clinical trials. Phase II focused on preliminary biomechanical evaluation of the HV sock with a series of laboratory-based pilot studies. Particularly, surface electromyography (EMG) assessed muscle activation patterns, adductor hallucis, while plantar pressure mapping evaluated changes in forefoot pressure distribution and the first ray alignment while performing dynamic tasks. The studies provided evidence of a tangible mediation by reducing medial deviation of the first metatarsal, and increasing optimal loading patterns throughout the gait with the HV sock. Phase III involved a randomized controlled clinical trial with 100 participants diagnosed with mild to moderate HAV. Participants were randomly assigned to either conservative podiatric care (control group) or conservative podiatric care plus daily use of the HV sock (intervention group) during the trial of six months. Significant outcome measures included the change in HAV angle (clinically), foot function (Foot Function Index), pain intensity (Visual Analogue Scale), and patients’ quality of life (Manchester-Oxford Foot Questionnaire). Using mixed linear model and statistical tests, clinically and statistically significant improvement was demonstrated in all outcome measures in the intervention group by using eleven months with the HV sock, including a change in HAV angle that significantly exceeded established minimal clinically important difference thresholds than control group.
