Quadricepts Muscle, Muscle Strain, Rehabilitation, Athletic Injuries


Objective: To describe the management of a female high-school varsity track athlete with a Grade 2 quadriceps strain sustained only 10 days before her state qualifying meet.

Clinical Features: An 18-year-old female varsity runner sustained a Grade 2 quadriceps strain during practice while transitioning from a light jog to a sprint. The strain was felt at the end of the toe-off phase.

Intervention and Outcome: She was treated with a combination of multimodal chiropractic intervention, instrument-assisted soft tissue mobilization (IASTM), rehabilitative exercises, and dry needling with electric stimulation. An initial 5 treatments over 7 days allowed her to fully return to competition, where she set personal records in the 100m and 200m dashes at the first subsectional meet. An additional treatment was provided a week later, after which she competed at the state meet and set personal records in the 100m and 400m dashes.

Conclusion: Quadriceps strain is a common athletic injury causing athletes to miss time away from sport. This case demonstrates how a patient with a Grade 2 quadriceps strain was treated over the course of 7 days and was able to return to competition.
