What is the best way to treat shin splints?
All great answers. The first concern is to lay off exercises and movement that may aggravate the problem. Ice and elevation following exercise, lots of ankle rotations in both directions, new shoes with a bit stiffer sole may be in order.
One exercise to try to strengthen the anterior tibialis that can be performed with elastic bands. Have your client sit facing you with knees in full extension. Plantar flex one foot though full ROM, wrap the band across the dorsal surface at mid-metasarsals, then dorsiflex against the band’s resistance. Perform on both legs.
Also, be sure to increase the large muscle rhythmic warm-up time prior to increased to pace to training intensity.
Good luck.
