STUDY DESIGN: Case report. BACKGROUND: Little evidence exists about impairments and perceived disability following eversion injury to the deltoid ligament. This case study prospectively examined the neuromuscular, biomechanical, and psychological consequences of a case of a medial ankle sprain. CASE DESCRIPTION: A recreationally active man with a history of a lateral ankle sprain (grade I) was participating in a university Institutional Review Board-approved research study examining the neuromuscular and mechanical characteristics associated with chronic ankle instability. Twentytwo days after the testing session, the participant sustained an eversion injury to his left ankle while playing basketball. OUTCOMES: The outcomes of this case are presented using the International Classification of Functioning, Disability and Health model. Outcome variables were assessed at preinjury (medial ankle sprain), 3 months postinjury, and 5 months postinjury. Measurements included neural excitability of the soleus, balance assessment, joint stability, and psychological assessments. Data from this case study revealed that a medial ankle sprain reduces joint mobility and alters neural excitability of the soleus, with concurrent deficits in balance and self-reported function. These impairments forced the participant to downgrade his physical activity lifestyle up to 5 months postinjury. DISCUSSION: These data suggest the need for the development of intervention strategies to address impairments in neural excitability and joint mobility at the ankle to help patients meet the goal of maintaining long-term joint health. LEVEL OF EVIDENCE: Prognosis, level 4.
