Table 5.

Recommendations for standardized protocol with the provided rationale for the recommendation.

Recommendation	Rationale
Shoes off	Individuals attend testing in a variety of footwear so it is difficult to standardize.
Six practice trials	Learning effect.
Video instruction	Increases efficiency of testing protocol and standardizes instruction.
Standard testing order	Minimize fatigue by alternating stance limbs. Improves consistency in administration of test.
Stance foot aligned at most distal aspect of toes	Keeps starting point in a uniform and reproducible position to which the reach foot can be referenced.
Stance foot movement is allowed	Difficult to reliably determine if heel/forefoot is lifted from the surface.
Body movement allowed under control	Difficult to standardize amount of movement allowed.
Normalized to limb length	Normalization standardizes measurement to each individual.
Standard reach height	Allows reach height to be uniform.
