What Is a Muscle Strain?

A muscle strain occurs when muscle fibers are overstretched, overloaded, or partially torn during activity. This type of injury often develops during sudden movements, heavy lifting, sprinting, jumping, twisting, reaching, or athletic activities that place high demand on the muscles.

Muscle strains can affect many areas of the body, including the hamstrings, calves, quadriceps, groin, hip flexors, lower back, neck, shoulders, and forearms. They are common in athletes, gym-goers, active workers, runners, recreational sports players, and individuals returning to activity after time away.

A strain can range from mild overstretching to a more significant tear. Mild strains may feel like tightness, soreness, or discomfort during movement. More significant strains may involve sharp pain, swelling, bruising, weakness, or difficulty using the affected muscle.

The body naturally begins repairing strained muscle tissue through inflammation, tissue rebuilding, and remodeling. However, recovery is not only about waiting for the tissue to heal. The injured muscle must gradually regain strength, flexibility, coordination, and tolerance to load. Without proper rehab, the body may create compensation patterns that increase strain in nearby joints and tissues.

Individuals May Experience

• Localized muscle pain or tenderness

• Tightness or stiffness in the affected area

• Swelling or mild bruising

• Weakness when using the muscle

• Pain when stretching or contracting the muscle

• Difficulty performing certain movements or activities

• Sharp pain during sport, lifting, or sudden movement

• Reduced flexibility or range of motion

• Muscle guarding around the injured area

• Difficulty returning to workouts, running, or sport

• Recurring tightness after activity

• Compensation through nearby joints or muscles

What Contributes to Muscle Strains?

Muscle strains may occur due to:

• Sudden forceful movements

• Muscle fatigue during activity

• Inadequate warm-up before exercise

• Reduced flexibility

• Muscle imbalances

• Repetitive overuse during sport or work

• Poor movement mechanics

• Limited joint mobility

• Previous unresolved injuries

• Sudden increase in training intensity

• Poor recovery between workouts or work demands

• Weakness in supporting muscle groups

Often, muscle strains develop when muscles are asked to perform beyond their current capacity. This may happen when a muscle is forced to contract quickly, stretch suddenly, absorb load, or stabilize a joint under fatigue.

Muscle strain risk may also increase when surrounding joints are not positioned or moving well. If a bone or joint sits in a mechanically altered position, the muscles attaching to that region may become either lengthened, shortened, overactive, or inhibited. This can change how force travels through the tissue and make the muscle more vulnerable to being overstretched or overloaded.

For example, altered pelvic positioning may place the hamstrings or hip flexors under constant tension. Limited hip mobility may increase strain through the groin or lower back. Poor shoulder positioning may overload the rotator cuff, biceps, or upper back muscles. When the body is not aligned or moving efficiently, certain muscles may have to work harder than they should.

How Manual Therapy May Help

Manual therapy and rehabilitation may help support muscle strain recovery by improving movement, reducing protective tension, restoring tissue mobility, and correcting compensation patterns. The goal is not only to reduce pain, but to improve the mechanical environment around the injured muscle so it can recover with better function.

Care may focus on the injured tissue itself, as well as the joints, fascia, posture, strength, and movement patterns that may have contributed to the strain.

Osteopathic Manual Therapy

Osteopathic Manual Therapy may focus on how nearby joints, bones, fascia, and movement patterns influence the injured muscle. Muscles attach to bones, and their length, tone, and function are heavily influenced by the position and mobility of the joints they cross.

When bones or joints are not moving efficiently, the attached muscles may be placed in a disadvantageous position. Some tissues may become chronically lengthened and vulnerable to overstretching, while others may become shortened, compressed, or overactive. This can alter muscle tension, reduce coordination, and increase the likelihood of strain during sudden movement or load.

Osteopathic treatment may include:

• Improving mobility in nearby joints

• Reducing fascial tension surrounding the muscle

• Addressing compensatory movement patterns

• Supporting coordinated movement through the injured region

• Assessing how surrounding joints contribute to load distribution

• Improving pelvic, spinal, shoulder, hip, or rib mechanics when relevant

• Reducing protective guarding around the injured area

• Supporting more balanced muscle length and joint positioning

• Improving how force transfers through the movement chain

For prevention, osteopathic care may help identify areas where joint positioning or mobility limitations are placing muscles under unnecessary strain. By improving the way bones and joints move, the muscles attached to them may be able to contract, relax, lengthen, and absorb force more efficiently.

Osteopathic treatment often considers how the entire movement chain influences the injured muscle, rather than only treating the area where pain is felt.

Physiotherapy

Physiotherapy rehabilitation plays a key role in recovering from muscle strains. Once the initial irritation begins to settle, the injured tissue usually needs progressive loading to rebuild strength, flexibility, endurance, and confidence.

Treatment may involve:

• Progressive strengthening exercises

• Controlled stretching and mobility work

• Gradual reintroduction of activity

• Functional movement retraining

• Sport-specific rehabilitation when appropriate

• Education on activity modification during recovery

• Isometric, eccentric, and concentric loading when appropriate

• Return-to-running, lifting, or sport progression

• Correcting movement patterns that contributed to the strain

• Strengthening surrounding muscles to reduce future risk

These rehabilitation strategies help restore strength and function to the injured muscle. Physiotherapy also helps reduce the risk of re-injury by ensuring the muscle can tolerate the demands of daily activity, work, workouts, or sport before full return.

Massage Therapy

Massage therapy may support recovery by addressing muscular tension, protective guarding, and soft tissue stiffness in the affected region. After a muscle strain, nearby muscles often tighten to protect the area, which may limit movement and contribute to discomfort.

Treatment may include:

• Reducing tightness in surrounding muscles

• Supporting circulation to the affected region

• Addressing protective muscle guarding

• Improving flexibility in surrounding tissues

• Supporting recovery between rehabilitation sessions

• Reducing compensatory tension above or below the injured area

• Improving comfort during the recovery process

Massage therapy can help relieve muscular tension and support tissue recovery, especially when combined with strengthening, mobility work, and gradual return-to-activity planning.

Book an Assessment

If a muscle strain is affecting your ability to move comfortably, exercise, work, or participate in sport, our team can assess contributing movement factors and guide a safe recovery plan.

A comprehensive assessment can help identify whether your strain may be related to muscle weakness, joint positioning, limited mobility, poor movement mechanics, compensation patterns, training load, or unresolved previous injuries.
