We measured temporal parameters by manually delineating onsets and offsets of syllables in the oscillograms and created spectrograms to measure mean peak frequency (MPF) (FFT length, 1,024; frame, 100%%; overlap, 75%%; Hamming window) using the "automatic parameter measurements setup" with interactive element separation from section labels, that is, based on the manual delineation in oscillograms.
This was achieved by measuring the standard temporal parameters termed force latency (FL) and contraction time (CT) [ 13, 14], and force during the patellar tendon reflex.
Gait data were obtained using the GAITRite™ walkway system to measure temporal and spatial parameters.
This technique has been validated with different populations [ 111, 112] and found to be a reliable [ 112, 113] instrument to measure spatial and temporal parameters of gait.
We measured frequency and temporal parameters from 230 great calls (mean: 13.5 calls per animal; range: 2 27).
Conclusions: Based on this data, GAITRite is a valid and reliable tool for measuring selected spatial and temporal parameters of gait.
In a previous study on individual recognition [35], we did not find any evidence for voice characteristics in skylarks, i.e. the within-individual variation of song frequency and temporal parameters measured was greater than the between-individual variation.
The adapted algorithm proved valid for measuring spatio-temporal parameters for ski-mountaineering on treadmill.
Given the role of the actin cytoskeleton in morphological aspects of synaptic plasticity [9], our next aim was to measure temporal changes of the structural parameters described above.
Temporal parameters were measured with a resolution of 2.9 ms, and MPF was measured with a frequency resolution of 43 Hz.
Outcome measures were gait speed and spatial and temporal parameters of footfall and trunk acceleration, derived from an electronic gait mat and accelerometers.
