What Is Lateral Epicondylitis?

Lateral epicondylitis, commonly known as tennis elbow, refers to irritation or overloading of the tendons that attach to the outside of the elbow. These tendons are connected to the forearm muscles that help extend the wrist and fingers, stabilize the wrist during gripping, and support lifting, carrying, typing, tool use, and repetitive hand activity.

Despite the name, tennis elbow does not only affect tennis players. It is common in many populations, including office workers, tradespeople, gym-goers, racquet sport athletes, golfers, cooks, cleaners, healthcare workers, mechanics, construction workers, and anyone who performs repetitive gripping, lifting, twisting, or wrist extension tasks.

Tennis elbow often develops gradually. At first, symptoms may appear only during activity, such as gripping a racquet, lifting a bag, opening a jar, using a computer mouse, typing for long periods, or holding tools. Over time, the tendons may become more sensitive, and daily tasks such as shaking hands, pouring a kettle, carrying groceries, or lifting a coffee mug may become painful.

Although the term “tendinitis” is commonly used, many persistent tendon problems are more accurately related to tendon overload and reduced tendon capacity rather than simple inflammation alone. This is why rehabilitation often focuses on gradually improving the tendon’s ability to tolerate load.

Individuals May Experience

• Pain on the outside of the elbow

• Tenderness around the lateral epicondyle

• Forearm tightness or aching

• Weak grip strength

• Pain when gripping objects

• Discomfort when lifting or carrying items

• Pain with typing, mouse use, or desk work

• Pain when using tools, turning a screwdriver, or opening jars

• Discomfort during racquet sports, golf, climbing, or gym training

• Pain with wrist extension or resisted gripping

• Morning stiffness or sensitivity around the elbow

• Symptoms that improve with rest but return with activity

• Reduced confidence using the affected arm

What Contributes to Lateral Epicondylitis?

Several factors may contribute to tendon irritation or overload around the outside of the elbow, including:

• Repetitive gripping activities

• Increased workload involving the hands or forearms

• Overuse during sport, manual work, or gym training

• Sudden increase in lifting, typing, tool use, or racquet activity

• Reduced strength or endurance in the forearm muscles

• Limited mobility in the wrist or elbow

• Poor shoulder or scapular mechanics

• Neck, shoulder, or upper back tension affecting arm mechanics

• Poor ergonomic setup for keyboard or mouse use

• Repetitive wrist extension under load

• Previous elbow, wrist, shoulder, or neck injuries

• Inadequate recovery between repetitive tasks

These factors may increase strain on the tendons of the elbow. The elbow does not work in isolation. The wrist, hand, shoulder blade, shoulder, neck, and upper back all influence how force travels through the arm. If the shoulder is not stabilizing well, the forearm may work harder during gripping and lifting. If the wrist is stiff or the forearm muscles are overloaded, the tendon attachment at the elbow may become irritated.

For many people, tennis elbow becomes recurring because the pain settles temporarily, but the underlying tendon capacity, strength, ergonomics, or movement pattern has not fully improved.

How Manual Therapy May Help

Manual therapy and rehabilitation may help reduce mechanical strain around the elbow and improve how the upper limb handles load. The goal is not only to relieve elbow pain, but to identify why the tendon is being repeatedly overloaded.

Care may focus on improving wrist and elbow mobility, reducing forearm tension, restoring shoulder mechanics, gradually strengthening the tendon, and modifying aggravating activities such as typing, gripping, lifting, tool use, or sport.

Osteopathic Manual Therapy

Osteopathic Manual Therapy may evaluate how the elbow functions in relation to the wrist, forearm, shoulder, neck, ribs, and upper back. Since gripping and lifting involve the entire upper limb, restrictions outside the elbow may contribute to increased load through the forearm tendons.

Treatment may include:

• Assessing elbow and wrist mobility

• Addressing fascial tension in the forearm

• Evaluating shoulder and scapular mechanics influencing the elbow

• Improving upper back and rib mobility when posture affects arm mechanics

• Reducing compensatory tension through the neck, shoulder, and forearm

• Supporting coordinated movement of the upper limb

• Improving load transfer from the shoulder through the elbow and wrist

• Addressing restrictions that may increase strain during gripping or lifting

Osteopathic care often considers how the entire arm and upper body influence elbow movement and tendon loading.

Physiotherapy

Physiotherapy rehabilitation may focus on improving tendon capacity, strength, and movement patterns. Since tennis elbow is commonly linked to tendon overload, progressive loading is often a key part of recovery.

Treatment may include:

• Progressive strengthening exercises for the forearm muscles

• Isometric, eccentric, and concentric tendon loading when appropriate

• Grip strength training

• Wrist extensor strengthening

• Mobility exercises for the wrist and elbow

• Shoulder and scapular strengthening

• Activity modification strategies

• Ergonomic guidance for typing, mouse use, and desk setup

• Gradual return to gripping, lifting, sport, or work tasks

• Load management education

• Technique correction for racquet sports, lifting, or repetitive work

These exercises help improve the ability of the tendons to tolerate load. Rehabilitation is usually progressed gradually so the tendon becomes stronger without repeatedly flaring symptoms.

Massage Therapy

Massage therapy may help relieve tension in the forearm muscles and surrounding soft tissues. When the tendon attachment is irritated, the forearm muscles may become tight, guarded, or overworked.

Treatment may include:

• Reducing tightness in the forearm muscles

• Improving circulation in surrounding tissues

• Addressing trigger points in overused muscles

• Reducing tension through the wrist extensors and flexors

• Supporting relaxation of the shoulder, neck, and upper limb

• Helping improve comfort during recovery

• Supporting tissue mobility alongside strengthening and activity modification

Massage therapy may help relieve muscular tension contributing to elbow discomfort, but it is often most effective when combined with progressive strengthening and movement-based rehabilitation.
