Functional hallux limitus tests:
1) Patient seated or supine – with one thumb load the first metatarsal head by applying a dorsiflexory force to the sesamoids using moderate pressure with other hand dorsiflex hallux while maintaining load on first metatarsal head. If can not get up to 10-15º of motion suggests functional hallux limitus. Has been shown to have a sensitivity of 0.72 and a specificity of 0.66 for assumed abnormal midtarsal joint motion associated with the compensation for a functional hallux limitus (ref).
2) Patient standing on one foot – clinician attempts to dorsiflex hallux < 15º assumed to indicate functional hallux limitus These tests are not necessarily definitive for functional hallux limitus, but have to be considered in the context of other aspects of the evaluation, such as the presence of the compensations and symptoms of functional hallux limitus.
