Rest Allows the Stiffness to Become Chronic Concussion produces active muscle guarding. The body responds to injury by tightening surrounding muscles to protect the area. This guarding is appropriate acutely but becomes problematic when sustained. After concussion, the upper trapezius, suboccipital muscles, and cervical paraspinals tighten protectively. Sustained protection becomes chronic dysfunction (Treleaven, 2008). Joint immobilization compounds the muscle guarding. Cervical joints that do not move regularly develop stiffness. The capsules tighten. The synovial fluid stagnates. The proprioceptive input from the joints reduces. The combination of muscle guarding and joint stiffness produces the cervical dysfunction that contributes to many PCS symptoms. Rest preserves the protective pattern. Without active movement, the protective patterns remain engaged. The muscles stay tight. The joints stay stiff. The brain learns that the area is "injured" and maintains the protection. Rest perpetuates rather than resolves the cervical contribution to PCS. The cervical dysfunction drives many PCS symptoms. Cervicogenic headache, cervical dizziness, and cervical brain fog all come from the cervical dysfunction that develops with sustained rest. Addressing the cervical component directly often produces dramatic symptom improvement that rest-based approaches cannot achieve. How Stretching Helps Stretching releases protective muscle guarding. Gentle, sustained stretching activates the Golgi tendon organs that signal the brain to release muscle tension. The brain learns that movement is safe. The protective contraction releases. The cervical region begins functioning normally again. Stretching maintains joint mobility. Range-of-motion movement keeps joint capsules supple and synovial fluid circulating. The joints maintain the function they would lose with rest. The proprioceptive input continues, supporting the sensory integration that PCS recovery requires. Stretching improves cervical blood flow. The vertebral arteries that supply the brain stem pass through the cervical spine. Cervical stiffness impairs their flow. Restored cervical mobility supports blood flow that the recovering brain needs. Stretching reduces cervicogenic symptoms. The cervical contribution to headache, dizziness, and brain fog reduces with restored cervical function. Patients often experience symptom relief within minutes of effective stretching. The relief reflects the cervical contribution that was driving the symptoms. Mobility Support for Cervical Recovery JME 155 Diaphragmatic breathing supports the parasympathetic activation that allows muscle release. Sympathetic activation maintains muscle guarding. Breathing during stretching produces the parasympathetic state that allows the muscles to release fully. 10 breaths before stretching, slow breathing during each stretch hold. JME 14 Chin tucks are essential for cervical recovery. The exercise activates the deep cervical flexors that weaken after concussion. The strengthening reduces the load on the protective superficial muscles, allowing them to release. 10 repetitions with 5-second holds, multiple times daily. JME 1 Cervical rotation maintains the joint mobility that prevents the chronic stiffness pattern. The controlled, slow rotation provides the joint input that prevents capsular tightening. 10 repetitions each direction. JME 150 Thoracic rotation supports cervical recovery indirectly. Stiff thoracic spines force cervical compensation. Maintained thoracic mobility removes this compensation, allowing the cervical work to address the cervical problem directly. 8 repetitions per direction. Start your 3-day free trial for cervical-recovery mobility programming. The Right Way to Stretch After Concussion Gentle, not aggressive. Stretching should feel mildly uncomfortable, not painful. Aggressive stretching triggers protective contraction rather than release. The mild tension produces the response that builds toward release. Sustained holds (15-30 seconds). Brief stretches do not produce the neural changes that allow release. Sustained holds give the nervous system time to recognize the safety of the position and release the protective contraction. Breathe through the stretch. Holding breath during stretching prevents the parasympathetic activation that allows release. Continuous breathing throughout the stretch supports the muscle release. Multiple sessions per day, not one long session. Multiple short sessions (3-5 minutes, 3-4 times daily) produce better results than one long session. The repeated short stimulation reinforces the new movement patterns. Stretch within range, not beyond. The goal is restoring normal range, not exceeding it. Stretching beyond comfortable range produces injury and triggers more protective contraction. Stay within the range where the stretch feels productive. Daily Movement Routine JME 3 Lateral cervical flexion is the primary stretch for upper trapezius release. The chronic upper trapezius tension contributes substantially to cervicogenic headache. Daily stretching reduces this contribution. 8 repetitions per side with 15-second holds, multiple times daily during active recovery. JME 42 Shoulder circles release the shoulder tension that compounds cervical stiffness. The shoulders and neck share muscle attachments. Shoulder mobility supports cervical mobility. 10 repetitions each direction, multiple times daily. JME 15 Cervical extension reverses the protective head-forward position. The extension activates the deep cervical flexors and stretches the anterior structures. Daily extension is essential for cervical recovery. 8 repetitions, multiple times daily. JME 151 Lateral side bends with breathing combine cervical and trunk mobility with the breathing that supports muscle release. This exercise is particularly valuable for comprehensive cervical recovery. 8 repetitions per side. Address cervical stiffness with simplmobility's mobility programming. When Stretching Is Not Enough Persistent stiffness beyond 4-6 weeks needs professional treatment. Self-directed stretching addresses most cervical contributions to PCS. Stiffness persisting beyond 4-6 weeks of consistent stretching suggests joint dysfunction or muscle imbalance that requires hands-on physical therapy treatment. Find a concussion-specialized physical therapist. Not all PTs treat cervical dysfunction with concussion expertise. Specifically request a therapist with concussion training. The targeted treatment (joint mobilization, soft tissue work, motor control retraining) accelerates recovery beyond what self-stretching alone produces. Manual therapy plus exercise works best. The combination of hands-on therapy and home exercise produces better outcomes than either alone. Most patients see substantial improvement in 6-12 sessions when treated this way. Address contributing factors. Posture, ergonomics, sleep position, and stress all contribute to cervical dysfunction. Addressing these factors supports the stretching work and prevents recurrence. Should I stretch through pain? No. Stretching should produce mild discomfort, not pain. Pain triggers protective contraction and can produce additional injury. Stretch to the point of stretch sensation but not pain. The release happens within tolerable ranges. How long until stretching helps? Many patients notice immediate symptom relief from individual stretching sessions. Sustained reduction in cervical stiffness typically develops over 2-4 weeks of consistent practice. Full resolution of cervical contribution to PCS takes 4-8 weeks with consistent work plus appropriate treatment. Can I make my concussion worse by stretching? Gentle, appropriate stretching does not worsen concussion. Aggressive stretching, sudden movements, or stretching that produces dizziness can trigger symptom flares. The key is slow, gentle, sustained stretching with breathing. The right approach helps; the wrong approach can hurt. References Treleaven, J. (2008).
