17.3 Procedural versus declarative learning in gaitrehabiltation after stroke: A pilot study

Abstract

Albert T, Yelnik A, Colle F, Bonan I, Lassau JP. Anatomic motor point localization for partial quadriceps block in spasticity. Arch Phys Med Rehabil 2000;81:285-7. Objective: To identify the location of the vastus intermedius nerve and its motor point (point M) and to precisely identify its coordinates in relation to anatomic surface landmarks. Design: Descriptive study. Setting: Anatomy institute of a university school of medicine. Participants: Twenty-nine adult cadaver limbs immobilized in anatomic position. Intervention: Anatomic dissection to identify point M. Anatomic surface landmarks were point F, the issuing point of femoral nerve under the inguinal ligament; point R, the middle of superior edge of the patella; segment FR, which corresponds to thigh length; point M′, point M orthogonal projection on segment FR. Mean Outcome Measure: Absolute vertical coordinate, distance FM, relative vertical coordinate compared to the thigh length, FM′/FR ratio; absolute horizontal coordinate, distance MM′. Results: The absolute vertical coordinate was 11.7 ± 2cm. The relative vertical coordinate was at.29 ±.04 of thigh length. The horizontal coordinate was at 2 ±.5cm lateral to the FR line. Conclusion: Point M can be defined with relative precision by two coordinates. Application and clinical interest of nerve blocking using these coordinates in quadriceps spasticity should be studied. © 2000 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation
