In a normal clinical environment, foot function and treatment
efficacy is evaluated using static foot posture assessment. Whilst there are
several methods of static assessment, the longitudinal arch angle (LAA) has been
validated as a repeatable and reliable static measure that represents foot
posture during midstance whilst walking and running. The main aim of this study
was to assess if static LAA is representative of dynamic LAA with the use of
orthoses. METHOD: 17 male subjects with a mean age of 33.4 (SD 12.3) years, mean
height of 169.88 (SD 9.2) mm and a mean weight of 72.71 (SD 11.36)kg, who
provided an informed consent were included in the study. Orthotic prescription
was produced using measurements from a weightbearing goniometer. An
optoelectronic movement analysis system was employed to record and analyse the
LAA in barefoot, shoe and shoe with orthoses conditions. This data was collected
in a static standing condition and then repeated whilst walking. RESULTS: No
significant differences were observed between right static and right dynamic
barefoot condition t=1.329 (p=0.05). Same results were observed for right static
and right dynamic orthotic condition t=-.233 (p=0.05). Similarly, no significant
differences were recorded for left static and left dynamic barefoot condition and
orthotic condition t=.303 (p=0.05) and t=.049 (p=0.05) respectively. However,
differences were observed within the shoe only condition. CONCLUSION: LAA is been
shown to be a good static measure for dynamic foot function and can reliably be
implemented in a normal clinical environment to evaluate and assess the efficacy
of the prescribed foot orthoses.
