Groin Strains: A Common Sport Injury
“Groin strains are injury to the adductor, hip flexor or abdominal muscles found along the inside of the thigh.”
Groin strains are an uncomfortable injury that can result in prolonged symptoms if not managed. This means that physiotherapy and recovery are key parts of getting back to activity. This injury is commonly found in sports that involve sudden acceleration, deceleration, direction change, and jumping (ex. hockey, soccer, rugby, etc.). Groin injuries account for 10-11% of all injuries in professional hockey and soccer.
Injury can occur due to blunt trauma (getting kicked), forceful contraction (ex. kicking), and microtrauma (repetitive injury). Symptoms can vary depending on the severity of the strain, but symptoms include loss of function or strength, pain in groin, swelling and tenderness, and bruising.
This injury can involve up to 3 muscle groups:
Adductors
Abdominal group
Iliopsoas group (hip flexors)
Risk factors include:
Age
Hip range of motion
Abductor and adductor strength
Previous groin injury
Sport specific measures (40m sprint, broad/vertical jump)
A recent study by Evans (2019) shed some light on how to approach rehab with this injury. When recovering from a groin strain, here is the approximate timeline and treatment approach for this injury:
Phase 1: 0-2 weeks
Pain management: restore range of motion
Short lever Copenhagen isometric holds - 3 x fatigue
Bridge + adduction 3 x 7 reps
Planks 3 x 30sec
Phase 2: 2-6 weeks
Increased loading tolerance:
Resisted adduction 3 x 10 reps
Long lever Copenhagen hold 3 x fatigue
Banded clamshells 3 x 10
Phase 3: 6-10 weeks
Full pain free strength and increased balance + stability
Long lever Copenhagen active adduction 3 x 10 reps
Banded squats 3 x 7 reps
Banded side stepping 3 x fatigue
Lateral sliders 3x7
Phase 4: 10-12+ weeks
Sport specific rehab:
Kettle bell lateral lunges 3 x 7 reps
Skaters 3 x fatigue
Single leg hurdle side jumps 3xfatigue
Altitude landing 3 x fatigue
