Abstract

The paper discusses the use of accelerometry as an alternative to electromyography or subjective judgement in the assessment of functional disability. The apparatus described is an accelerometer with an f.m.-f.m. telemetry transmitter, coupled to an f.m. receiver, signal conditioner, subcarrier demodulator and twin integrator to generate positional information from acceleartion. The capabilities and limitations of accelerometry are discussed, typical recordings are presented, and interpretation of recordings is described. It is concluded that the method is well worth pursuing.

Sommaire

Ce rapport examine l'accélérométrie en tant qu'autre méthode, outre l'électromyographie ou le jugement subjectif, servant à évaluer l'incapacité des fonctions. L'appareillage décrit est un accéléromètre avec émetteur de télémesure f.m./f.m., couplé à un récepteur f.m., un conditionneur de signaux, un d''emodulateur de sous-porteuse, et un intégrateur double servant à produire des informations positionnelles à partir de l'accélération. L'article traite des possibilités et des limitations de l'accélérométrie, présente des enregistrements types, et décrit l'interprétation des enregistrements. Il termine en affirmant que la méthode devrait être poursuivie.

Zusammenfassung

Dieser Beitrag behandelt die Verwendung der Beschleunigungsmessung als eine Alternative zur Elektromyographie oder der subjektiven Beurteilung bei der Bewertung von funktioneller Invalidität. Der beschriebene Apparat ist ein Beschleunigungsmesser mit FM/FM-Fernmeßsender, gekoppelt mit einem FM-Empfänger, Signalaufbereiter, Zwischenträger-Demodulator und Zwillingsintegrator zur Erzeugung der Positionsinformation aus der Beschleunigung. Die Möglichkeiten und Grenzen der Beschleunigungsmessung werden erörtert, typische Aufzeichnungen präsentier und eine Interpretation dieser Aufzeichnungen beschrieben. Es wird der Beschluß gefaßt, daß die Methode weiter verfolgt werden sollte.
