Hip Flexor Strain

What is a Hip Flexor Strain?

The hip flexors are muscles in the front of the hip that lift the thigh toward the body. A strain occurs when these muscles are overstretched or torn, often during sprinting, kicking, or sudden directional changes.

Common Symptoms

• Sharp pain in the front of the hip or groin

• Pain with sprinting, kicking, or rising from a seated position

• Tenderness over the hip flexor muscles

• Possible bruising or swelling in acute injuries

Physical Therapist Diagnosis

A PT assesses strength, range of motion, and pain with resisted hip flexion or stretching. Palpation and functional movement testing confirm the diagnosis.

Why it Happens

Hip flexor strains are common in athletes who sprint, kick, or perform explosive hip movements. Fatigue, tightness, being underprepared and inadequate warm-up are common risk factors.

Why it Doesn’t Always Heal on Its Own

Mild strains may improve with rest, but incomplete rehab can leave lingering weakness or tightness, increasing the risk of re-injury.

Ideal Physical Therapy Treatment

Rehab focuses on reducing pain, restoring flexibility, and gradually building strength and explosiveness. Dry needling is highly effective for reducing muscle tightness and promoting healing in strained hip flexors.

Key strategies include:

• Manual therapy and stretching to restore flexibility

• Dry needling to release muscle spasm and promote recovery

• Progressive strengthening of hip flexors, glutes, and core

• Movement retraining for sprinting and kicking mechanics

• Gradual return-to-sport progression

Expected Outcomes

Most hip flexor strains recover within a few weeks, depending on severity. Proper rehab will accelerate the recovery process and ensures a safe and efficient return to play.
