Inner Elbow Stretches: Techniques, Benefits, and Nerve Glides

By Alex 7 min read

Stretching the inner elbow effectively involves gentle, consistent movements targeting forearm flexor muscles and performing ulnar nerve glides to improve flexibility, prevent injury, and alleviate discomfort.

How to stretch the inner elbow?

Stretching the inner elbow primarily involves targeting the forearm flexor muscles and, in some cases, mobilizing the ulnar nerve. Effective stretching requires understanding the underlying anatomy and performing specific movements gently and consistently.

Understanding the "Inner Elbow"

When people refer to the "inner elbow," they are typically pointing to the area around the medial epicondyle – a bony prominence on the humerus (upper arm bone) where several important structures attach or pass through. This region is critical for forearm and hand function, housing:

  • Forearm Flexor Muscles: A group of muscles originating from the medial epicondyle that allow you to flex your wrist and fingers (e.g., pronator teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris, flexor digitorum superficialis). Tightness in these muscles is a common cause of discomfort.
  • Medial Collateral Ligament (MCL): Provides stability to the elbow joint, resisting valgus (outward) stress.
  • Ulnar Nerve: One of the three main nerves of the arm, it passes through a groove behind the medial epicondyle (often called the "funny bone") before continuing down the forearm to innervate parts of the hand. Compression or irritation of this nerve can cause numbness, tingling, and pain in the pinky and ring fingers.

Why Stretch This Area? Stretching the inner elbow and its associated forearm muscles can help:

  • Alleviate Tightness: Reduce muscle stiffness from repetitive tasks or strenuous activity.
  • Prevent Injury: Address issues like medial epicondylitis (golfer's elbow), which is an inflammation of the tendons attaching to the medial epicondyle.
  • Improve Flexibility: Enhance range of motion in the wrist and elbow, beneficial for various sports and daily activities.
  • Reduce Nerve Irritation: Gentle nerve glides can help mobilize the ulnar nerve, potentially easing symptoms of cubital tunnel syndrome.

Principles of Effective Stretching

Before attempting any stretches, adhere to these fundamental principles to ensure safety and efficacy:

  • Warm-Up First: Never stretch cold muscles. Perform 5-10 minutes of light cardiovascular activity (e.g., arm circles, light jogging, dynamic movements) to increase blood flow to the muscles.
  • Be Gentle and Gradual: Stretches should feel like a mild pull, not pain. Never force a stretch or bounce.
  • Hold Static Stretches: For static stretches, hold each position for 20-30 seconds. Repeat 2-3 times per side.
  • Breathe Deeply: Maintain slow, controlled breathing throughout the stretch. Exhale as you deepen the stretch.
  • Consistency is Key: Regular stretching yields the best results. Aim for at least 3-5 times per week.

Specific Stretches for the Inner Elbow and Forearm Flexors

These stretches target the muscles and structures around the inner elbow.

Forearm Flexor Stretch (Palm Down, Fingers Down)

This is the primary stretch for the forearm flexors originating from the medial epicondyle.

How to Perform:

  1. Extend your arm straight out in front of you, palm facing down, elbow straight.
  2. Point your fingers towards the floor.
  3. With your opposite hand, gently grasp the fingers of the outstretched hand.
  4. Pull your fingers back towards your body, keeping your elbow straight. You should feel a stretch along the top of your forearm and near the inner elbow.
  5. Hold for 20-30 seconds.
  6. Release and repeat 2-3 times.

Muscles Targeted: Primarily the wrist and finger flexors (e.g., flexor carpi radialis, flexor carpi ulnaris, flexor digitorum superficialis).

Wrist Flexor Stretch (Palm Up, Fingers Down)

This variation provides a slightly different angle of stretch for the forearm flexors.

How to Perform:

  1. Extend your arm straight out in front of you, palm facing up, elbow straight.
  2. Point your fingers towards the floor.
  3. With your opposite hand, gently grasp the fingers of the outstretched hand.
  4. Pull your fingers back towards your body, keeping your elbow straight. You should feel a stretch along the underside of your forearm.
  5. Hold for 20-30 seconds.
  6. Release and repeat 2-3 times.

Muscles Targeted: Similar to the previous stretch, but can emphasize different fascicles of the forearm flexors.

Wall or Table Forearm Flexor Stretch

This allows for a deeper stretch by using an external surface.

How to Perform:

  1. Stand facing a wall or table.
  2. Place the palm of the hand you want to stretch flat against the wall or table, with your fingers pointing downwards and towards your body. Your elbow should be straight.
  3. Gently lean forward or shift your body weight away from the hand, increasing the stretch in your forearm and inner elbow.
  4. Adjust your distance from the wall/table to control the intensity.
  5. Hold for 20-30 seconds.
  6. Release and repeat 2-3 times.

Muscles Targeted: Forearm flexors.

Ulnar Nerve Glides (Nerve Mobilization)

These are not "stretches" in the traditional sense, but rather movements designed to help the ulnar nerve slide smoothly through its pathway, reducing potential irritation. Perform these gently and stop if you experience any sharp pain, increased numbness, or tingling.

How to Perform:

  1. Start with your arm bent, hand near your ear, palm facing you, like you're talking on a phone.
  2. Gently tilt your head away from the hand.
  3. Slowly extend your fingers and wrist away from your head, as if pushing the phone away.
  4. Reverse the movement, bringing your hand back to your ear and tilting your head towards your hand.
  5. Repeat 5-10 times, moving smoothly through the range of motion. Do not hold the end position.

Purpose: To improve the mobility of the ulnar nerve, which runs through the inner elbow.

Common Mistakes to Avoid

  • Overstretching or Bouncing: Can lead to muscle strains or micro-tears. Always move slowly and gently.
  • Stretching Cold Muscles: Increases the risk of injury and reduces the effectiveness of the stretch.
  • Ignoring Pain: A stretch should feel like a pull, not a sharp or radiating pain. Pain is a signal to stop.
  • Incorrect Form: Ensure your elbow remains straight (unless otherwise specified) to properly target the forearm muscles.

When to Seek Professional Advice

While stretching can be highly beneficial, some symptoms warrant professional evaluation:

  • Persistent Pain: If pain in your inner elbow doesn't improve with rest, stretching, or activity modification.
  • Numbness, Tingling, or Weakness: Especially if it radiates down your forearm into your pinky and ring fingers, as this could indicate nerve compression (cubital tunnel syndrome).
  • Sudden or Acute Injury: If you experience sharp pain after a specific incident.
  • Lack of Improvement: If regular stretching and self-care don't alleviate your symptoms after a few weeks.

A physical therapist, sports medicine physician, or other qualified healthcare professional can provide an accurate diagnosis and develop a tailored treatment plan.

Conclusion

Targeted stretching of the forearm flexors and gentle nerve glides can be highly effective in maintaining the health and flexibility of the inner elbow region. By understanding the anatomy, adhering to proper stretching principles, and listening to your body, you can prevent discomfort, improve performance, and enhance your overall arm health. Incorporate these stretches consistently into your routine, and remember that patience and persistence are key to achieving lasting results.
