Impairment of Weight Support of Lower Limbs after Spinal Cord Hemisection in Rhesus Monkeys / 中国康复理论与实践

ABSTRACT

@#Objective To observe the influence of spinal cord injury on lower limbs weight support capacity,and the changes with time. Methods Six adult female rhesus monkeys with thoracic(T7-9)right spinal cord hemi-section were measured the plantar pressure ratio of both lower limbs with Foot-Scan system before,and six and twelve weeks after operation. Results There was no statistical difference between both sides of limbs before operation(Z=-1.330,P>0.05),while the plantar pressure ratio was more on the left limbs six and twelve weeks after operation(Z>4.783,P<0.001).The plantar pressure ratio of right lower limb became less and less during observation(Z=3.191,P<0.001). Conclusion The weight support capacity of affected limbs is injured after spinal cord hemi-section in monkeys, and would become worse without intervention.
