Abstract:

Objective To observe the effect of quadriceps femoris spasticity on the movement parameters in stroke patients during obstacle crossing.

Methods From October, 2017 to November, 2018, 20 stroke patients were divided into spasticity group (n = 11) and non-spasticity group (n = 9) based on the score of modified Ashworth Scale (MAS) of quadriceps femoris. A 10-camera 3D motion analysis system and two force plates were used to synchronously measure the movement parameters of the patients during obstacle crossing of 15 cm high, such as step length, step width, anterior-posterior velocity of the center of mass (COMAPV) and medio-lateral velocity of the center of mass, toe-obstacle distance of unaffected limb, toe-obstacle clearance of affected limb, heel-obstacle distance, double support phase, and the swing phases of affected and unaffected limb.

Results Compared with the non-spasticity group, the COMAPV decreased as both affected and unaffected limb above the obstacle in the spasticity group (F > 10.006, P < 0.01), as well as the toe-obstacle distance and step length before obstacle crossing (F > 13.456, P < 0.01); while, the double support phase and the step width after obstacle crossing increased (F > 4.533, P < 0.05).

Conclusion The quadriceps femoris spasticity may make the strategy of obstacle crossing more carefully for stroke patients, and less efficiently.
