Electromyogram–Lengthening Velocity Relation in Plantar Flexors During Stance Phase of Gait in Patients With Hypertonia After Acquired Brain Injury John W. Chow, PhD, Stuart A. Yablon, MD, Dobrivoje S. Stokic, MD, DSc Archives of Physical Medicine and Rehabilitation Volume 93, Issue 12, Pages 2287-2294 (December 2012) DOI: 10.1016/j.apmr.2012.03.020 Copyright © 2012 American Congress of Rehabilitation Medicine Terms and Conditions

Fig 1 Computation of MG EMG-LV slope and goodness of fit during stance phase of a gait cycle. EMG (solid line) and lengthening velocity (dashed line) data pairs during the lengthening portion of stance (A) are used for regression analysis (B). The gait cycle on the MA side is shown for a TBI patient with the AS of 4 in the MA plantar flexors. Abbreviation: LS, shank length; %MAX, percent of the maximum EMG.

Fig 2 Procedure for deriving different EMG-LV parameters in a representative subject: the overall average gain from positive and negative slopes (step 1), frequency and average gain of positive slopes (step 2, A and B), and frequency and average gain of significant positive slopes (step 3, C and D). Each cross represents a gain of the slope during stance of a gait cycle, calculated as in figure 1. Abbreviations: LS, shank length; %s/LS, percent of the maximum EMG per LS/s.
