Interlimb Coordination During the Stance Phase of Gait in Subjects With Stroke Andreia S.P. Sousa, PhD, Augusta Silva, PhD, Rubim Santos, PhD, Filipa Sousa, PhD, João Manuel R.S. Tavares, PhD Archives of Physical Medicine and Rehabilitation Volume 94, Issue 12, Pages 2515-2522 (December 2013) DOI: 10.1016/j.apmr.2013.06.032 Copyright © 2013 American Congress of Rehabilitation Medicine Terms and Conditions

Fig 1 Intervals used to assess the interlimb relation during the stance phase of walking in stroke subjects were defined using the variation of the ground reaction force. The intervals are shown for each series: when the ipsilesional limb was the trailing limb and the contralesional limb was the leading limb (A) and when the ipsilesional limb was the leading limb and the contralesional limb was the trailing limb (B). Abbreviations: CoM, center of mass; CONTRA, contralesional limb; DS, double-support phase; Fx, mediolateral component; Fy, anteroposterior component; Fz, vertical component; IPSI, ipsilesional limb; LEAD, leading limb; TRAIL, trailing limb; TS, terminal stance.

Fig 2 Representation of statistically significant correlations between limbs found in the stroke group. Statistically significant correlations occurred in electromyographic activity between the paretic trailing limb and the nonparetic leading limb during the double-support phase (A) and between the nonparetic trailing limb during terminal stance and the paretic leading limb during the double-support phase (B) and (C). Abbreviations: DS, double-support phase; LEAD, leading limb; TRAIL, trailing limb; TS, terminal stance (significant value, P<.05).

Fig 3 Mean (bars) ± SD (error bars) of propulsive and braking impulse observed in paretic and nonparetic limbs of subjects with stroke and healthy controls during the double-support phase and terminal stance. Abbreviations: DS, double-support phase; LEAD, leading limb; TRAIL, trailing limb; TS, terminal stance (significant values, P<.05).

Fig 4 Mean (bars) ± SD (error bars) values of the percentage of trailing limb propulsive contribution of the paretic and nonparetic limbs of subjects with stroke and of trailing limb propulsion contribution in healthy controls during the double-support phase (significant values, P<.05).
