CKC DF is another part of a comprehensive Return to Sport Testing & Pre-Participation Physicals. Below are a few highlights of the CKC DF test.
Hoch et. al. 2011 & Hoch et. al. 2012: The weight bearing lunge test (WBLT) explained a significant portion of the variance within the anterior reach distance signifying this direction of the Star Excursion Balance Test (SEBT) may be a good clinical test to assess the effect of dorsiflexion range of motion restrictions on dynamic balance. The Y Balance Test was developed in order to improve methodology and testing efficiency of the SEBT.
Marcrum et. al. 2012 Results- Altering ankle DF starting position during double leg squat resulted in increased knee valgus and medial knee displacement, decreased quad activation & increased soleus activation. These changes are similar to those seen in individuals with PFPS.
Keep up the great work; Your building a better testing system.
