EMBalance - validation of a decision support system in the early diagnostic evaluation and management plan formulation of balance disorders in primary care: study protocol of a feasibility randomised controlled trial

BackgroundBalance problems are caused by multiple factors and often lead to falls and related fractures, bringing large socio-economic costs. The complexity of balance control mechanisms, the lack of medical expertise, and the absence of specialised equipment contribute to the delayed or incorrect diagnosis and management ofthese patients. Advances in computer science have allowed the development of computer systems that support clinical diagnosis and treatment decisions based on individualised patient data. The aim of the EMBalance decision support system (DSS) is to support doctors facing this clinical challenge, to make a definitive diagnosis and implement an effective management plan. The EMBalance study will determine the accuracy of this supportive tool when used by non-specialist doctors. This study is funded by the European Union’s Seventh Framework Programme.Methods/designEMBalance is a proof-of-concept study designed as a non-commercial, international, multi-centre, single-blind, parallel-group randomised controlled trial to be carried out at four clinical sites in the United Kingdom, Germany, Greece and Belgium. The study is comprised of three stages: internal pilot, phase I (diagnosis) and stage II (management). For this purpose, 200 patients presenting with persistent dizziness (>3 months’ duration) to primary care services will be randomised to either the intervention group (diagnostic assessment with the DSS) or a control group (diagnostic assessment without the DSS). Patients allocated to the intervention group will be assessed by a doctor with the support of the EMBalance DSS, while patients allocated to the control group will receive a visit as per standard practice. Ultimately, all patients’ diagnoses and management plans will be certified by a consultant in neuro-otology.DiscussionEMBalance is the first trial to test the accuracy of a DSS in both the diagnosis of and the management plan for vestibular disorders across the healthcare systems of four different countries. The EMBalance study is the result of a combined effort of engineers and physicians to develop an accurate tool to support non-specialist doctors, with no risk for the patient. This trial will provide reliable information about the benefits of implementing DSSs in primary care while supporting the feasibility of testing the EMBalance algorithms in further research.

Perception of unsteadiness in patients with dizziness: association with handicap and imbalance

Dizziness is a common problem in patients seeking medical help and is often associated with imbalance and handicap. This study aimed to reveal whether the perception of unsteadiness could be an indication of greater imbalance and handicap in these patients. Patients with dizziness were categorized into two groups, steady patients (n = 15) and unsteady patients (n = 23), based on the presence or absence of self-perceived unsteadiness. The level of self-perceived handicap was evaluated by the Dizziness Handicap Inventory. Static balance ability was evaluated using a force platform and the center of pressure motion was calculated during various quiet standing conditions. Dynamic balance ability was evaluated by the functional forward reach test and Dynamic Gait Index. All the patients also went through isometric strength tests of the lower extremities. It was found that all patients reported themselves to be handicapped by dizziness. Patients who perceived themselves to be unsteady had greater handicap and poorer static standing, but did not differ from the steady patients in regard to muscle strength or functional balance tests. Thus, self- perceived unsteadiness was associated with greater handicap and poorer static balance in dizzy patients. In clinical management of these patients, special attention should be paid to balance and handicap.
