44 years old patient with LT leg weakness due to Spinal Disc Herniation
Patient was asked to go up and down the slope in a ‘heel to toe’ form. This narrows the base of support, thereby increases balance difficulty, and demands increased muscle activation and balance reaction.
The intense muscle activation causes the patient to lose control over his (weak) left knee extension when going up. He assists the handrails to maintain balance, and the stance phase on his left leg is slightly shorter than the right leg.
When the patient goes down the slope, he assists his hands more during the left leg stance.
