Abstract
The role of the basal ganglia in the coordination of different body segments and utilization of motor synergies was investigated by analyzing reaching movements to remembered three-dimensional (3D) targets in patients with Parkinson's disease (PD). Arm movements were produced alone or in combination with a forward bending of the trunk, with or without visual feedback. Movements in PD patients were more temporally segmented, as evidenced by irregular changes in tangential velocity profiles. In addition, the relative timing in the onsets and offsets of fingertip and trunk motions were substantially different in PD patients than in control subjects. While the control subjects synchronized both onsets and offsets, the PD patients had large mean intervals between the onsets and offsets of the fingertip and trunk motions. Moreover, PD patients showed substantially larger trial-to-trial variability in these intervals. The degree of synchronization in PD patients gradually increased during the movement under the influence of visual feedback. The mean and variability of the intersegmental intervals decreased as the fingertip approached the target. This improvement in timing occurred even though the separate variability in the timing of arm and trunk motions was not reduced by vision. In combined movements, even without vision, the PD patients were able to achieve normal accuracy, suggesting they were able to use the same movement synergies as normals to control the multiple degrees of freedom involved in the movements and to compensate for the added trunk movement. However, they were unable to recruit these synergies in the stereotyped manner characteristic of healthy subjects. These results suggest that the basal ganglia are involved in the temporal coordination of movement of different body segments and that related timing abnormalities may be partly compensated by vision. Abnormal intersegmental timing may be a highly sensitive indicator of a deficient ability to assemble complex movements in patients with basal-ganglia dysfunction. This abnormality may be apparent even when the overall movement goal of reaching a target is preserved and normal movement synergies appear to be largely intact.

These results suggest that the basal ganglia are involved in the temporal coordination of movement of different body segments and that related timing abnormalities may be partly compensated by vision. Abnormal intersegmental timing may be a highly sensitive indicator of a deficient ability to assemble complex movements in patients with basal-ganglia dysfunction. This abnormality may be apparent even when the overall movement goal of reaching a target is preserved and normal movement synergies appear to be largely intact.</s0></fC01><fC02 i1="01" i2="X"><s0>002B17G</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Mouvement corporel</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Body movement</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Movimiento corporal</s0><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Membre supérieur</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Upper limb</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Miembro superior</s0><s5>02</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Tronc</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Trunk</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Tronco</s0><s5>03</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Coordination</s0><s5>04</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Coordination</s0><s5>04</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Coordinación</s0><s5>04</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Mouvement orienté</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Goal directed movement</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Movimiento orientado</s0><s5>05</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Segment corporel</s0><s5>06</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Body segment</s0><s5>06</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Segmento corporal</s0><s5>06</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Synergie</s0><s5>07</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Synergism</s0><s5>07</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Sinergia</s0><s5>07</s5></fC03><fC03 i1="08" i2="X" l="FRE"><s0>Noyau gris central</s0><s5>08</s5></fC03><fC03 i1="08" i2="X" l="ENG"><s0>Basal ganglion</s0><s5>08</s5></fC03><fC03 i1="08" i2="X" l="SPA"><s0>Núcleo basal</s0><s5>08</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Précision</s0><s5>10</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Accuracy</s0><s5>10</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Precisión</s0><s5>10</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Contrôle moteur</s0><s5>11</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Motor control</s0><s5>11</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Control motor</s0><s5>11</s5></fC03><fC03 i1="11" i2="X" l="FRE"><s0>Parkinson maladie</s0><s5>12</s5></fC03><fC03 i1="11" i2="X" l="ENG"><s0>Parkinson disease</s0><s5>12</s5></fC03><fC03 i1="11" i2="X" l="SPA"><s0>Parkinson enfermedad</s0><s5>12</s5></fC03><fC03 i1="12" i2="X" l="FRE"><s0>Homme</s0><s5>54</s5></fC03><fC03 i1="12" i2="X" l="ENG"><s0>Human</s0><s5>54</s5></fC03><fC03 i1="12" i2="X" l="SPA"><s0>Hombre</s0><s5>54</s5></fC03><fC07 i1="01" i2="X" l="FRE"><s0>Système nerveux pathologie</s0><s5>45</s5></fC07><fC07 i1="01" i2="X" l="ENG"><s0>Nervous system diseases</s0><s5>45</s5></fC07><fC07 i1="01" i2="X" l="SPA"><s0>Sistema nervioso patología</s0><s5>45</s5></fC07><fC07 i1="02" i2="X" l="FRE"><s0>Système nerveux central pathologie</s0><s5>46</s5></fC07><fC07 i1="02" i2="X" l="ENG"><s0>Central nervous system disease</s0><s5>46</s5></fC07><fC07 i1="02" i2="X" l="SPA"><s0>Sistema nervosio central patología</s0><s5>46</s5></fC07><fC07 i1="03" i2="X" l="FRE"><s0>Encéphale pathologie</s0><s5>47</s5></fC07><fC07 i1="03" i2="X" l="ENG"><s0>Cerebral disorder</s0><s5>47</s5></fC07><fC07 i1="03" i2="X" l="SPA"><s0>Encéfalo patología</s0><s5>47</s5></fC07><fC07 i1="04" i2="X" l="FRE"><s0>Extrapyramidal syndrome</s0><s5>48</s5></fC07><fC07 i1="04" i2="X" l="ENG"><s0>Extrapyramidal syndrome</s0><s5>48</s5></fC07><fC07 i1="04" i2="X" l="SPA"><s0>Extrapiramidal síndrome</s0><s5>48</s5></fC07><fC07 i1="05" i2="X" l="FRE"><s0>Maladie dégénérative</s0><s5>49</s5></fC07><fC07 i1="05" i2="X" l="ENG"><s0>Degenerative disease</s0><s5>49</s5></fC07><fC07 i1="05" i2="X" l="SPA"><s0>Enfermedad degenerativa</s0><s5>49</s5></fC07><fN21><s1>001</s1></fN21></pA></standard></inist><affiliations><list><country><li>Canada</li><li>Russie</li><li>États-Unis</li></country><region><li>District fédéral central</li><li>New Jersey</li></region><settlement><li>Moscou</li><li>New Brunswick (New Jersey)</li></settlement><orgName><li>Université Rutgers</li></orgName></list><tree><country name="États-Unis"><region name="New Jersey"><name sortKey="Poizner, H" sort="Poizner, H" uniqKey="Poizner H" first="H." last="Poizner">H.
