Abstract
AbstractBackgroundChronic ankle instability (CAI) is a complex clinical entity that commonly includes ankle-foot impairment.ObjectiveTo investigate the effects of midfoot joint mobilizations and a one-week home exercise program (HEP) compared to a sham intervention and HEP on pain, patient-reported outcomes (PROs), ankle-foot joint mobility, and neuromotor function in young adults with CAI.MethodsTwenty participants with CAI were instructed in a stretching, strengthening, and balance HEP and were randomized a priori to receive midfoot joint mobilizations (forefoot supination, cuboid glide and plantar 1st tarsometatarsal) or a sham laying-of-hands. Changes in foot morphology, joint mobility, strength, dynamic balance, and PROs assessing pain, physical, and psychological function were assessed pre-to-post treatment and one-week following. Participants crossed-over to receive the alternate treatment and were assessed pre-to-post treatment and one-week following. Linear modelling was used to assess changes in outcomes.ResultsParticipants who received midfoot mobilization demonstrated significantly greater perceived improvement immediately posttreatment in the single assessment numeric evaluation (Sham: 5.0±10.2%; Mobilization: 43.9±26.2%; β: 6.8 p<0.001, Adj R2:0.17) and Global Rating of Change (Sham: −0.1±1.1; Mobilization: 1.1±3.0; β: 1.8 p=0.01, Adj R2:0.12). Following the mobilization intervention, participants demonstrated greater improved rearfoot inversion mobility (Sham: 4.4±8.4°; Mobilization: −1.6±6.1°; β: −6.37, p=0.01, Adj R2:0.19), plantarflexion mobility (Sham: 2.7°±6.4; Mobilization: −1.7°±4.3; β: −4.36, p=0.02, Adj R2:0.07), and posteromedial dynamic balance (Sham: 2.4±5.9%; Mobilization: 6.0±5.4%; β: 3.88, p=0.04, Adj R2:0.10) compared to controls at 1-week post-treatment.ConclusionParticipants with CAI who received midfoot joint mobilization had greater perceived improvement and physical signs that may benefit this clinical population.
