Efficacy of corrective spinal orthoses on gait and energy consumption in scoliosis subjects

Adolescent idiopathic scoliosis (AIS) is a progressive growth disease
that affects spinal anatomy, mobility, and left-right trunk symmetry. As a
consequence, AIS can modify human gait. Spinal orthoses are a commonly used
conservative method for the treatment of AIS. OBJECTIVE: This review evaluated
the AIS spinal orthosis literature that involved gait and energy consumption
evaluations. STUDY DESIGN: Literature review. METHOD: According to the population
intervention comparison outcome measure methods and based on selected keywords,
10 studies met the inclusion criteria. RESULTS: People with AIS who wore a spinal
orthosis, compared with able-bodied participants, walked slower with decreased
hip and pelvic movements, decreased hip mediolateral forces, ground reaction
force asymmetry, and excessive energy cost. Pelvis and hip frontal plane motion
decreased when wearing an orthosis. Hip and pelvis movement symmetry improved
when using an orthosis. Ankle and foot kinematics did not change with orthotic
intervention. People with AIS continued to have excessive energy expenditure with
an orthosis. CONCLUSION: Spinal orthoses may be considered for improving the
walking style, although energy cost does not decline following the orthotic
intervention. Implications for Rehabilitations Problems related to scoliosis
include reduced quality of life, disability, pain, postural alterations, sensory
perturbations, standing instability and gait modifications. Wearing corrective
spinal orthoses in AIS subjects produce a reduction in walking speed and cadence,
increase in stride length and reduction of gait load asymmetry compared to
without brace condition. Spinal orthoses do not decline excessive energy
expenditure to walk versus without it.
