Introduction. In patients with Friedreich's Ataxia, an accurate assessment of balance function is essential in physiotherapy care, as it can provide a better orientation for rehabilitation choices. The stabilometric platform is an electromedical instrument that, in combination with traditional assessment scales, can provide additional information on balance skills. Such information can have a positive impact in the clinic. Objectives. The main objective of this thesis project is to investigate whether an assessment with a stabilometric platform, integrated with a traditional assessment protocol, can define a more detailed picture of the functional profile of the patient with Friedreich’s Ataxia and whether it is more sensitive to changes in the clinical picture. The second objective is to validate the stabilometric platform as a neuromotor assessment tool, demonstrating correlations and inferences between the platform data and those of traditional assessment scales. Materials and methods. Eleven patients with Friedreich's Ataxia admitted to the IRCSS E. Medea of “La Nostra Famiglia” in Pieve di Soligo were recruited. These patients underwent an initial assessment (T0) and a post-treatment assessment (T1). The protocol used included: Scale for the Assessment and Rating of Ataxia (SARA) and Modified Friedreich Ataxia Rating Scale (mFARS); Medical Research Council (MRC); Berg Balance Scale (BBS); 6 Minutes Walking Test (6MWT) and Timed ‘Up and Go’ (TUG). A stabilometric assessment using a Tecnobody ProKin252 platform was added to this protocol. A statistical analysis of the collected data was carried out using Kendall's Tau B correlation test and the Mann-Whitney U comparison test, considering results with P-Value < 0.05 to be significant. Results. The stabilometric assessment provides clinical information on the sample that is useful to the physiotherapist. The main ones being: displacement of the centre of pressure on the forefoot, greater difficulties of load transfer in the sagittal plane and presence of continuous postural adjustments in standing. The data provided by the Limits of Stability (LOS) and general platform parameters are more sensitive than traditional assessment scales. The correlations and inferences between the LOS and all scales of the traditional protocol were significant; the perimeter also reported significant correlations with some scales, but requires further investigation. Conclusions. The stabilometric platform was a consistent assessment tool in identifying the deficits observed with the traditional scales and was able to offer more information on the functional profile of the sample, as well as being more sensitive in post-treatment re-evaluation. Given the statistical results, the use of LOS in the neuromotor assessment can be validated, while the other parameters can be used as supplementary. Further studies are needed to confirm and validate the results of this work.
Introduzione. Nei pazienti affetti da Atassia di Friedreich un’accurata valutazione delle funzioni di balance risulta fondamentale, all’interno della presa in carico fisioterapica, poiché può contribuire ad orientare meglio le scelte riabilitative. La pedana stabilometrica è uno strumento elettromedicale che, associato alle tradizionali scale valutative, può dare informazioni aggiuntive sulle competenze di balance. Tali informazioni possono avere una ricaduta positiva nella clinica. Obiettivi. L’obiettivo principale di questo progetto di tesi è di indagare se una valutazione con pedana stabilometrica, integrata ad un protocollo di valutazione tradizionale, possa definire un quadro più dettagliato del profilo funzionale del paziente con Atassia di Friedreich e se essa sia più sensibile ai cambiamenti del quadro clinico. Il secondo obiettivo è quello di validare la pedana stabilometrica come strumento di valutazione neuromotoria, dimostrando delle correlazioni e delle inferenze fra i dati della pedana e quelli delle tradizionali scale di valutazione. Materiali e metodi. Sono stati reclutati 11 pazienti con Atassia di Friedreich, ricoverati presso l’IRCSS E. Medea de “La Nostra Famiglia” di Pieve di Soligo. Questi pazienti sono stati sottoposti a una valutazione iniziale (T0) e a una valutazione post-trattamento (T1). Il protocollo utilizzato ha previsto: Scale for the Assessment and Rating of Ataxia (SARA) e Modified Friedreich Ataxia Rating Scale (mFARS); Medical Research Council (MRC); Berg Balance Scale (BBS); 6 Minutes Walking Test (6MWT) e Timed “Up and Go” (TUG). A questo protocollo è stata aggiunta una valutazione stabilometrica mediante pedana Tecnobody ProKin252. È stata svolta un’analisi statistica dei dati raccolti tramite il test di correlazione di Kendall’s Tau B ed il test di confronto di Mann-Whitney U, considerando significativi i risultati con P-Value < 0,05. Risultati. La valutazione stabilometrica ha fornito informazioni cliniche sul campione utili al fisioterapista. Le principali sono: spostamento del centro di pressione sull’avampiede, maggiori difficoltà di spostamento di carico sul piano sagittale e presenza di continui aggiustamenti posturali in stazione eretta. I dati forniti dai Limiti di Stabilità (LOS) e dai parametri generali della pedana risultano maggiormente sensibili delle scale di valutazione tradizionali. Sono risultate significative le correlazioni e le inferenze tra i LOS e tutte le scale del protocollo tradizionale; anche il perimetro ha riportato delle correlazioni significative con alcune scale, ma richiede ulteriori indagini. Conclusioni. La pedana stabilometrica è risultata uno strumento valutativo coerente nell’individuare i deficit osservati con le scale tradizionali ed è stata in grado di offrire maggiori informazioni sul profilo funzionale del campione, oltre ad essere maggiormente sensibile nella rivalutazione post-trattamento. Visti i risultati statistici, si può validare l’utilizzo dei LOS nella valutazione neuromotoria, mentre gli altri parametri possono essere utilizzati come integrativi. Ulteriori studi sono necessari per confermare e validare i risultati raggiunti con questo lavoro.
