The Effect of Additional Neuromuscular Training on Peri-Ankle Muscle Morphology and Function in Chronic Ankle Instability Subjects: A Randomized Controlled Trial.

Background: Lateral ankle sprain is one of the most common musculoskeletal issues during sports and activities of daily living. This study investigated the effect of combined neuromuscular training and conventional training (including strengthening, range of motion, and balance exercises) on muscle morphology, dynamic balance, perceived ankle instability, and functional capacity in persons with chronic ankle instability (CAI).

Hypothesis: The combination of neuromuscular and conventional training programs might result in additional benefits on the morphology of muscle, dynamic balance, and functional capacity in subjects with CAI.

Reliability of musculoskeletal ultrasonography for peri-ankle muscles in subjects with unilateral chronic ankle instability.

Background: Ankle sprain is a common problem among active people and athletes. It causes reduces their activity of daily living and quality of life. Because of the impaired muscle strength and neuromuscular and postural control, it seems that the morphological criteria of peri-ankle muscles are changed.
