BackgroundIdiopathic toe walking is a diagnosis of exclusion characterized by a persistent toe-toe gait pattern after three years of age. Treatment for toe walking includes physical therapy, orthotics, casting, Botulinum Toxin A injection into gastrocnemius/soleus muscles, and/or surgery; yet, little evidence exists regarding long-term treatment effects.Research QuestionThe objective of this study was to explore the differences in longer-term gait outcomes and severity of idiopathic toe walking between children treated actively with casting or inactively following recommendations for stretching.MethodsForty-three adolescents and young adults (14.3-28.8 years; 21 females, 22 males) who had participated in an idiopathic toe walking classification study as children, returned for repeat physical examination and three-dimensional computerized gait analysis (13.4 years follow-up, range 9.4-17.8 years); 23 participants had received active treatment with casting and ankle foot orthotics +/− Botulinum Toxin A injection as children and 20 participants had received inactive treatment with recommended stretching exercises. Gait analysis data were compared retrospectively from baseline to follow-up using analysis of variance; toe walking severity was compared using a Wilcoxin Signed-Rank Sums test.ResultsAnkle angle at initial contact, peak dorsiflexion in stance, and toe walking severity improved significantly in the active treatment group only at follow-up. Significant improvement in peak ankle power and timing of ankle kinematics and kinetics in the gait cycle were found in both groups; however, greater changes occurred in the active treatment group. Both groups showed significantly improved internal plantar flexor moments, whereas knee extension increased in stance and passive ankle dorsiflexion decreased in both groups at follow-up (p = 0.001). Intermittent toe walking was reported in 49% (21/43) of participants at follow-up.SignificanceThe results of this study suggest that improvement in ankle kinematic timing and ankle kinetic gait analysis variables is sustainable, independent of conservative treatment for idiopathic toe walking in childhood.
