Cervical Spasms in Sports Medicine: Assessment and Management

There is irrefutable evidence of an association between mechanical neck pain (MNP) and dysfunction of the muscles of the cervical spine. For an athlete, the neck is a critical structure, responsible for supporting the head, absorbing shock, and facilitating complex movements essential for performance. When the intricate network of cervical muscles malfunctions, leading to painful spasms and stiffness, it can be a debilitating and career-threatening issue. From my clinical experience in sports medicine, I've seen how what starts as minor neck stiffness can escalate into chronic dysfunction if not properly addressed. The key is understanding that cervical spasms are often a symptom of a deeper problem involving impaired muscle behavior and neuromuscular control. [1]

Understanding the anatomy of cervical muscle dysfunction is key to effective treatment.

This article will delve into the complexities of cervical muscle dysfunction in athletes, exploring the differences between deep and superficial muscle groups, the methods for assessment, and the modern, evidence-based management strategies used in sports medicine to restore function and prevent recurrence.

The Imbalance: Superficial vs. Deep Cervical Muscles

The cervical muscles exhibit impairments in both their physical structure (such as cross-sectional area, fatty infiltration, fiber type) and behavior (timing and activation level). These changes impair the muscles' ability to generate, sustain, and maintain the precision of torque necessary for optimal function. A crucial concept in understanding neck pain is the dysfunctional relationship that develops between the superficial "mover" muscles and the deep "stabilizer" muscles.

• Superficial Muscles: These are the larger muscles on the outside, like the sternocleidomastoid (SCM) and scalenes. Their primary job is to produce large movements of the head and neck. In athletes with neck pain, these muscles become overactive, tense, and prone to spasms. Research shows heightened activity and delayed relaxation of these muscles after contractions. [2]
• Deep Muscles (Deep Neck Flexors): These are smaller muscles, such as the longus colli and longus capitis, located close to the vertebrae. Their main role is to provide segmental stability, controlling the position of each vertebra. In neck pain states, these crucial stabilizers become inhibited, showing delayed activation and reduced function.

This heightened superficial muscle activity is likely compensatory to deep cervical muscle inhibition. The big muscles try to do the job of the small stabilizers, a task they are not designed for. This leads to fatigue, strain, and painful spasms, creating a vicious cycle of pain and dysfunction that reduces an athlete's maximal strength, endurance, and repositioning acuity.

Assessment and Diagnosis in the Athletic Population

A thorough assessment by a sports medicine professional is vital to develop an effective treatment plan. The goal is to identify the underlying cause of the spasms, not just treat the symptom.

The clinical evaluation for a cervical strain or sprain typically includes:

Assessment Component	Purpose and Procedure
History Taking	Understanding the mechanism of injury (e.g., traumatic whiplash in football vs. insidious onset in a cyclist), location and nature of pain, and aggravating factors.
Range of Motion (ROM)	Assessing active and passive ROM in all planes (flexion, extension, rotation, lateral flexion) to identify limitations and pain-provoking movements.
Palpation	Feeling the cervical musculature to pinpoint areas of spasm, tenderness, and trigger points, especially in the SCM, scalenes, and upper trapezius.
Neurological Screen	Testing strength (myotomes), sensation (dermatomes), and reflexes to rule out nerve root compression or more serious spinal cord issues.
Functional Testing	Specific tests like the Cranio-Cervical Flexion Test (CCFT) are used to directly assess the endurance and control of the deep neck flexor muscles.

The prevalence of neck pain among athletes is high, making accurate and early diagnosis crucial for timely and effective management. [3]

Modern Management and Rehabilitation Strategies

Interventions focusing on retraining cervical muscle function have shown favorable outcomes. The management of cervical injuries in athletes is a multi-faceted approach aimed at reducing pain, restoring mobility, and correcting the underlying neuromuscular imbalance.

1. Pain and Spasm Control: In the acute phase, modalities like ice, heat, or electrical stimulation may be used. Manual therapy techniques, including soft tissue massage and joint mobilizations, are highly effective at reducing muscle guarding and improving mobility. Some clinicians may also use techniques like dry needling to release stubborn trigger points.
2. Deep Neck Flexor Re-education: This is the cornerstone of rehabilitation. It starts with low-load exercises focused on activating the inhibited deep stabilizers. The CCFT is not just an assessment tool but also a therapeutic exercise. The athlete learns to perform a gentle head nod ("chin tuck") without activating the superficial SCM muscles.
3. Postural Correction: Many athletes develop a forward head posture, which strains the posterior neck muscles and facilitates the dysfunctional pattern. Exercises and cues to promote a neutral cervical spine posture are integrated into all activities.
4. Progressive Strengthening and Integration: Once the deep stabilizers are firing correctly, the program progresses to more functional strengthening that integrates the neck and scapular muscles. This ensures the neck is stable during complex, sport-specific movements. [4]

This active approach, focused on restoring proper muscle function, is far more effective for long-term resolution than passive treatments alone.

In summary, cervical spasms in athletes are rarely an isolated issue. They are typically a manifestation of underlying cervical muscle dysfunction, characterized by overactive superficial muscles compensating for inhibited deep stabilizers. A comprehensive sports medicine approach requires a thorough assessment to identify these imbalances. Effective management focuses on a rehabilitation program that first reduces pain and spasm, then systematically retrains the deep neck flexors, corrects posture, and integrates stable neck function into sport-specific movements. This active, neuromuscular approach is essential to not only alleviate the current symptoms but also to restore optimal cervical muscle health and prevent future injury.
