Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA): A rehabilitation perspective

Abstract

the BAASTA battery, which consists of a series of perceptual timing and sensory timing tasks. Single wireless inertial sensors were placed on the patient's lower limbs. A computerized algorithm providing automatic detection of FEs during SIP, Timed Up and Go test and 20 m walk has been used. Results Preliminary results show that there is some discrepancy between patients self-assessment, SIP and walking task measurements. The occurrence of freezing episodes is highly variable in mild freezers and depends on the emotional context and the repetition of the tasks. This could be explained by the fact that the timing of our assessment has been performed in less severe off state than in Nantel's study(12 hours off Dopa) and which is closer to the patients' daily life. Discussion/conclusion SIP is of limited interest in the assessment of freezing in patients with partial ''on state''. Analysis of correlations with neurological status, kinematics, perceptual and motor timing tasks will aid in clarifying the interest of this new task in the assessment of freezing in PD patients.

Keeping the Beat: A Large Sample Study of Bouncing and Clapping to Music

“…The present findings question the methods currently used to identify individuals with synchronization difficulties. So far the existing test batteries assess synchronization abilities through finger tapping (e.g., [ 37 , 62 , 63 ]). Our findings suggest that researchers may be missing whole categories of individuals showing synchronization difficulties, as would have been the case in the present study if we had used clapping only.…”
