The developmen. of efficien. water oxidation.catalysts(WOCs)is of key importan.e in.order to drive sustain.ble reductive processes aimed at producin. ren.wable ***,two n.vel din.clear complexes,[(Cp^*Ir)2(μ-κ^3-O,n.O-H4-EDTMP)](Ir-H4-EDTMP,H4-EDTMP^4-=ethylen.diamin. tetra(methylen. phosphon.te))an.[(Cp^*Ir)2(μ-κ^3-O,n.O-EDTA)](Ir-EDTA,EDTA^4-=ethylen.diamin.tetraacetate),were syn.hesized an. completely characterized in.solution.by multin.clear an. multidimen.ion.l n.R spectroscopy,an. in.the solid state,by sin.le crystal X-Ray *** were supported on.o rutile TiO2 n.n.crystals obtain.n.

Objective: This study was con.ucted to in.estigate an. compare the coordin.tio n.an. stabilization.of axial segmen.s durin. walkin. with an. without horizon.al volun.ary head turn., in.healthy (n.5) an. hemiparetic (n.10) subjects. Methods : Subjects were in.tructed to turn.the head as fast an. as soon.as possible in.t he direction.in.icated by an.illumin.ted arrow sign.l(right, left or n.n.) that was triggered at in.tial con.act of the right (healthy) or paretic (hemiparetic) foot. Head, thorax,an. pelvis motion. were obtain.d from a 9-segmen. model usi n. retro-reflective markers an. a Vicon.512 system with 6 high-resolution.cam eras. Coordin.tion.of axial segmen.s in.the horizon.al plan. was characterized u sin. cyclographs an. cross-correlat- ion.an.lyses. Stabilization.of the segmen.s was quan.ified usin. root mean.squ are (RMS) values of the segmen.’s n.rmalized acceleration.profile. Results: The healthy subjects showed a direction.depen.en. modulation.of axial segmen. coor din.tion. with head turn. toward an. away from the stan.e limb favorin. an. hin. erin., respectively, the con.rarotation.l pattern.of the thorax with respect to the pelvis durin. locomotion. Mean.hile, pelvis motion. remain.d *** direction.specific modulation.pattern.was disrupted in.the hemiparetic subjects , both in.the spatial an. temporal ***, larger RMS values for head an. thorax segmen.s were observed in.the hemiparetic groups, both with an. witho ut the superimposition.of volun.ary head motion.. Con.lusion.:The fin.in.s sugge st that: (1) head rotation. durin. walkin. modify axial segmen. coordin.tion.in.a direction.specific man.er, (2) the pelvic rotation. associated with locomotio n.remain.d un.ffected by head rotation. an. (3) stroke alters this coordin.tion.behavior, which may con.ribute to balan.e dysfun.tion. durin. locomotion.
