Foot Levelers’ Stabilizers Decrease Q-Angle

By Kuhn DR, Yochum TR, Cherry AR, Rodgers SS, Nosco DL

Abstract

Objective: To evaluate the effects of full-length, custom-made flexible orthotics (Spinal Pelvic Stabilizers) on quadriceps angle (Q-angle) in volunteers with bilateral foot hyperpronation.

Methods: Forty chiropractic student volunteers were selected. Inclusion criteria were asymptomatic, male, evidence of bilateral hyperpronation, and no history of ankle surgery. Custom-made, flexible orthotics were produced. Subjects’ Q-angles were measured before and after orthotic insertion.

Results: Orthotic insertion demonstrated reduced Q-angle, in the direction of correction, in 39/40 test subjects.

Discussion: Research

suggests that the hyperpronated foot is an etiologic factor in many lower extremity complaints, including foot, knee, hip and low back pain. Literature indicates that custom-made, flexible orthotics can stabilize the pes planus foot and restore optimal degree of pronation. Reduced pronation decreases the amount of tibial and femoral internal rotation, with subsequent Q-angle reduction.

Conclusion: Full-length, flexible orthotics significantly improve the Q-angle in hyperpronating male patients and offer the possibility of long-term benefits.
