Introduction: Clinical measurements of strength in stroke subjects are usually performed and portable dynamometers are one of the most employed instruments. Objective: To verify the standardization procedures of the methods used to assess the strength of the trunk and upper limb muscles with portable dynamometers in stroke subjects, as well as to assess the psychometric properties which were al...

BACKGROUND Stroke is the most common and debilitating neurological disorder among adults, and is a sudden onset of neurological signs caused by brain blood vessels impairments. OBJECTIVES Some new therapeutic methods focus on the use of magnetic stimulation to produce therapeutic effects by inducing the currents. The aim of this study is to determine the effects of rTMS plus routine rehabilit...

[Purpose] The purpose of this study was to analyze intra-rater and inter-rater reliabilities of the make test, a manual muscle testing measurement method, using a hand-held dynamometer in Korean young adults. [Subjects and Methods] A total of 42 university students participated in this study. The make test, a manual muscle testing method, was conducted. A hand-held dynamometer was used to measu...

Drive-train bench system is utilized to test powertrain components of a vehicle such as transmission, torque converter, etc. In order to simulate the real vehicle motion, it is necessary that dynamometers of the drive-train bench simulates the various road conditions such as dry road surface and snow road surface, etc. To simulate the condition that the vehicle is running on the dry road, it is...

BACKGROUND Muscle training usually plays an important role in the treatment of shoulder disorders. Clinicians traditionally predict the pre-injury strength of an injured shoulder by using the contralateral uninjured side as the baseline data. OBJECTIVE The primary purpose of the present study was to determine the difference in isokinetic peak torque of dominant and nondominant shoulders. MA...

This paper presents modern vibration signalprocessing techniques for vehicle gearbox fault diagnosis, via the wavelet analysis and the Squared Envelope (SE) technique. The wavelet analysis is regarded as a powerful tool for the detection of sudden changes in non-stationary signals. The Squared Envelope (SE) technique has been extensively used for rolling bearing diagnostics. In the present work...

While operating a gear with local fault impulse is created, the high-frequency shock vibration is then generated and the vibration amplitude is modulated by the pulse force. Both the envelope and cepstrum analyses are useful tools to identify the fault frequencies and distinguish them from other frequency contents. Since the envelope analysis method provides an important and effective approach ...
