Tremor is the most common movement disorder, affecting 5.6% of the population with Parkinson’s disease or essential tremor over the age of 65.

Based on the research done in the field of tremors the only available data on tremor frequencies is of Parkinson’s patients. The damping system of the glove which works on the principle of friction requires the patient’s hand frequency, hand tremor velocities and acceleration.

Il tremore è il disturbo che colpisce il 5,6% della popolazione ed è tipicamente associato alla malattia di Parkinson oppore come tremore che si manifesta ad un’età superiore ai 65 anni. Convenzionalmente, le malattie come il Parkinson sono trattate con farmaci. Un trattamento sintomatico alternativo non invasivo è la soppressione meccanica del tremore. In questa tesi, sono state identificate le debolezze delle protesi indossabili per l'arto superiore presenti oggi sul mercato e viene presentata una soluzione innovativa che si avvantaggia dei cosiddetti compliant mechanisms. In generale, un guanto anti-tremore è progettato per tutti coloro che soffrono di queste malattie per facilitare il loro stile di vita. Il guanto è costituito da due parti principali: la prima consiste nel collegamento tra mano e avambraccio, che sfrutterà l’elasticità offerta dal Compliant Mechanism; il secondo consiste in un sistema di smorzamento sulla parte dell'avambraccio. Sulla base della ricerca condotta, i soli dati disponibili sulle frequenze di tremore sono relativi ai pazienti con Parkinson. La frequenza del tremore varia in un range di frequenza da 1,5 Hz a 9 Hz. Il guanto anti-tremore può essere sintonizzato per frequenze più elevate che lo renderebbero un prodotto completamente universale che sopprimerebbe tutti i tipi di tremore quando si effettuano ulteriori ricerche in questo senso.

Abstract
Tremor is the most common movement disorder, affecting 5.6% of the population with Parkinson’s disease or essential tremor over the age of 65. Conventionally, tremor diseases like Parkinson’s are treated with medication. An alternative non-invasive symptom treatment is the mechanical suppression of the oscillation movement. In this thesis, the weaknesses of past wearable tremor-suppression orthoses for the upper limb has been identified and with the use of compliant mechanisms a unique and efficient solution to suppress this type of hand tremor has been designed and developed. An Anti Tremor Glove is designed for the elderly and all those suffering from these diseases to ease their lifestyle. The glove consists of two principal parts one, is the compliant link connecting the hand to the forearm and two, the damping system on the forearm portion of the glove. Based on the research done in the field of tremors the only available data on tremor frequencies is of Parkinson’s patients. The damping system of the glove which works on the principle of friction requires the patient’s hand frequency, hand tremor velocities and acceleration. This glove is designed and engineered for people with Parkinson’s whose frequency of tremor ranges from low frequency values of 1.5 Hz to high frequency values up to 9 Hz. The Anti Tremor Glove can be tuned for higher frequencies which would make it a completely universal product which would suppress all tremor types when further research in this regard is done.File | Dimensione | Formato | |
