We present the case of a 54 year-old man presenting with a right Brown-Sequard
plus syndrome (BSPS) after a traumatic cervical spinal cord injury. After being
operated on with selective tibial neurotomy and triceps surae lengthening because
of a right spastic equinus foot, he developed a gait disorder at high speed. The
patient complained about an instability of the right knee. Observational gait
analysis exhibited an oscillating, flexion/extension motion of the right knee
during stance, which was confirmed by gait analysis. Dynamic electromyographic
recordings exhibited a clonus of the right rectus femoris (RF) during stance. The
spastic activity of the RF and the abnormal knee motion totally reversed after a
motor nerve block of the RF, as well as after botulinum toxin type A injection
into the RF. We emphasize that complex, spastic gait disorders can benefit from a
comprehensive assessment including gait analysis and nerve blocks.
