The use of knee-ankle-foot orthoses with drop locked knee joints
produces some limitations for walking in subjects with quadriceps muscle
weakness. The development of stance control orthoses can potentially improve
their functionality. OBJECTIVES: The aim of this review was to compare the
evidence of the effect of stance control orthoses to knee-ankle-foot orthoses
with drop locked knee joints in improving kinematic variables and energy
efficiency of walking by subjects with quadriceps muscle weakness caused by
different pathologies. STUDY DESIGN: Literature review. METHODS: Based on
selected keywords and their composition, a search was performed in Google
Scholar, PubMed, ScienceDirect, and ISI Web of Knowledge databases. In total, 18
articles were finally chosen for review. RESULTS: The results of this study
demonstrated that this type of orthosis can improve the walking parameters of
subjects with quadriceps muscle weakness and spinal cord injury patients when
compared to a locked knee-ankle-foot orthosis. CONCLUSION: There is evidence to
show that stance control orthosis designs improve the gait kinematics but not
energetic of knee-ankle-foot orthosis users. Development of new designs of stance
control orthoses to provide a more normal pattern of walking is still required.
CLINICAL RELEVANCE: Stance control orthoses are a new generation of orthotic
intervention that could potentially be significant in assisting to improve the
gait kinematics by knee-ankle-foot orthosis users.
