A woman in her 40s living in the Bashamichi area of Yokohama visited Spine Chiropractic with a primary complaint of chronic shoulder stiffness and neck pain.
She had experienced persistent shoulder stiffness for more than ten years. Initially, the symptoms were mild and manageable, but over the past two years they had gradually worsened. Since transitioning to remote work, the pain and stiffness had become significantly more severe, at times waking her during the night and affecting both her work performance and quality of life.
Whenever her symptoms flared up, she sought treatment from massage therapists, manual therapists, and chiropractors.
Some clinics provided little benefit after a single visit, while others offered temporary relief for a few sessions. Although chiropractic care tended to provide the longest-lasting improvement, the benefits eventually plateaued and her symptoms never completely resolved.
She told us openly,
“I wanted to try a different chiropractor because I felt there might be another way to address the underlying cause instead of just managing the symptoms.”
Since our clinic had recently opened near her home in Bashamichi, she decided to schedule an appointment.
The patient described persistent stiffness and aching extending from the neck into both shoulders.
As the workday progressed, the tightness spread into the upper back and around the shoulder blades, making it difficult to concentrate. She frequently rolled her shoulders and stretched her neck throughout the day simply to continue working.
The symptoms were considerably worse on the right side, which she estimated accounted for approximately 70% of her discomfort, compared with 30% on the left.
Light movement generally relieved the symptoms, and she noticed that she rarely thought about her neck while walking or being physically active outdoors.
Interestingly, she admitted that she often found herself unconsciously rotating her neck while sitting in restaurants because of the persistent stiffness.
Her partner would frequently comment,
“You can never seem to sit still.”
She denied headaches, numbness, tingling, or radiating pain into either arm.
Standing posture revealed mild elevation of the right shoulder.
Lateral postural analysis demonstrated several common postural changes associated with prolonged desk work, including:
These postural abnormalities became even more pronounced while sitting, suggesting that prolonged desk work and remote work were placing excessive mechanical stress on the cervical spine, upper back, and shoulder girdle.
Palpation revealed increased muscle tension throughout both the superficial and deep cervical musculature.
Significant hypertonicity was identified in the:
These muscles commonly become overloaded in individuals with chronic shoulder stiffness and forward head posture.
Cervical range of motion demonstrated mild restriction during right rotation and right lateral flexion.
Flexion and extension were within normal limits and did not reproduce pain.
During active elevation of the right shoulder, the patient reported a sensation of tightness rather than pain.
Further biomechanical assessment identified restricted joint motion throughout the cervical spine, cervicothoracic junction, and shoulder girdle.
Scapular movement was also asymmetrical, indicating altered shoulder mechanics that were likely contributing to her chronic symptoms.
A comprehensive orthopedic examination was performed to rule out cervical disc pathology and nerve root involvement.
The following orthopedic tests were negative:
Neurological examination revealed no evidence of cervical radiculopathy, cervical disc herniation, or other serious neurological disorders.
Based on the examination findings, the patient’s symptoms were most consistent with chronic mechanical neck pain and shoulder stiffness associated with postural dysfunction, cervical joint restriction, and shoulder girdle imbalance.
[Chiropractic Treatment]
Based on the examination findings, no red flags or significant contraindications to conservative care were identified. The patient’s condition was therefore considered appropriate for active chiropractic treatment.
Treatment began with Soft Tissue Therapy (STT) targeting the muscles responsible for her chronic neck and shoulder pain. Particular attention was given to the cervical and upper thoracic musculature, including the upper trapezius, levator scapulae, splenius muscles, and sternocleidomastoid, to reduce excessive muscle tension and improve soft tissue mobility.
After reducing muscular hypertonicity, treatment focused on restoring postural balance. Because chronic shoulder stiffness is often associated with poor posture rather than muscle tightness alone, we addressed the muscles responsible for maintaining proper alignment of the neck, shoulders, and upper back.
However, long-term improvement cannot be achieved by treating muscles alone.
The muscles responsible for posture and movement attach directly to bones and joints. If joint mobility remains restricted, abnormal muscle tension often returns even after successful soft tissue treatment.
For this reason, chiropractic management also included joint mobilization and chiropractic adjustments to restore normal biomechanics throughout the cervical spine and shoulder girdle.
Postural assessment demonstrated reduced cervical lordosis (commonly referred to as forward head posture or straight neck posture). Gentle cervical mobilization was therefore performed, followed by specific chiropractic adjustments to the C3/C4 and C6/C7 motion segments to improve cervical mobility and promote more normal spinal alignment.
Further examination identified anterior positioning of the right shoulder complex. Chiropractic adjustments were therefore applied to both the acromioclavicular (AC) joint and sternoclavicular (SC) joint to improve shoulder mechanics.
Evaluation of the scapulothoracic articulation also demonstrated excessive scapular abduction, contributing to rounded shoulders and increased mechanical stress on the neck.
Soft tissue techniques were applied to the muscles responsible for pulling the scapula outward, while chiropractic adjustments restored mobility to the right sixth and seventh ribs, improving coordinated movement between the rib cage and shoulder blade.
Finally, the patient received individualized advice regarding:
The primary goal was not only to relieve pain but also to reduce the likelihood of symptom recurrence by improving posture and movement patterns.
[Treatment Prognosis]
Immediately after the initial treatment, the patient reported a significant reduction in both neck pain and shoulder stiffness.
She also noticed that her posture felt more upright and relaxed without consciously trying to correct it.
“My shoulders feel much lighter, and I feel like I’m naturally standing taller.”
Because her symptoms had been present for more than ten years, we explained that correcting long-standing postural habits would require more than one treatment and scheduled a follow-up appointment one week later.
At her second appointment, the patient explained that some stiffness had gradually returned compared with immediately after the first treatment.
However, she estimated that her symptoms had improved to approximately 6 out of 10, compared with the initial severity.
She also reported fewer episodes of discomfort during work and found herself needing to stretch her neck less frequently throughout the day.
Treatment continued with further emphasis on improving cervical mobility, shoulder mechanics, and postural control.
Following the second treatment, the patient’s symptoms continued to improve.
Even after ten days, she rated her discomfort at approximately 3 out of 10, representing more than a 50% reduction compared with her initial presentation.
She reported being able to concentrate more effectively during work and no longer felt the need to constantly rotate or stretch her neck throughout the day.
Despite experiencing a particularly busy period at work, the patient successfully maintained her improvement by performing the home exercises that had been prescribed.
Her symptoms remained stable, and no significant flare-ups were reported.
Because both her posture and spinal function had improved consistently, we determined that treatment intervals could safely be extended.
At the patient’s request, care transitioned to a monthly maintenance program focused on preventing recurrence rather than treating active symptoms.
She currently attends approximately once per month, allowing her to maintain healthy spinal function despite continuing full-time desk work.
She commented,
“Before coming here, massage would only help for a few days. Now I can work comfortably for weeks without constantly thinking about my neck and shoulders.”
This case highlights the importance of addressing not only muscle tension but also joint function, posture, and movement patterns in patients with long-standing chronic shoulder stiffness and neck pain.

[Clinical Perspective]
This case represents one of the most common conditions we see in clinical practice—chronic shoulder stiffness and mechanical neck pain associated with prolonged desk work and poor posture.
Although many people believe chronic shoulder stiffness is simply caused by “tight muscles,” persistent symptoms are often the result of a combination of muscular imbalance, reduced joint mobility, and long-term postural adaptation.
In this patient’s case, the symptoms had persisted for more than ten years and had gradually become worse despite repeated massage therapy, manual therapy, and chiropractic care.
When discussing her previous treatments, she explained that most had focused primarily on relaxing tight muscles.
She commented that our explanation of how spinal and shoulder joint dysfunction could contribute to chronic shoulder stiffness was something she had never been told before.
Rather than concentrating solely on muscle tension, our assessment focused on identifying why those muscles had become chronically overloaded in the first place.
The patient was highly motivated to understand the underlying cause of her condition and actively participated in both treatment and her prescribed home exercise program, which contributed significantly to her progress.
Today, this pattern of chronic neck and shoulder pain has become increasingly common.
Since the COVID-19 pandemic, many office workers have transitioned to remote or hybrid work environments, resulting in longer periods of sitting and substantially less daily movement.
Reduced physical activity may contribute to:
These factors frequently contribute to the development and persistence of chronic neck pain and shoulder stiffness.
In this particular case, our examination identified several biomechanical contributors, including:
Rather than existing independently, these dysfunctions interacted with one another to place continuous mechanical stress on the neck and shoulders during prolonged desk work.
At Spine Chiropractic, we evaluate not only the painful area itself but also the overall movement of the cervical spine, thoracic spine, ribs, scapula, and shoulder complex to identify the underlying mechanical contributors to each patient’s symptoms.
While chronic shoulder stiffness does not necessarily progress into more serious spinal disorders, persistent postural dysfunction and long-term mechanical overload may increase the risk of recurrent musculoskeletal problems if left unaddressed.
These may include:
Early assessment and appropriate management often provide the best opportunity to improve symptoms, restore normal function, and reduce the likelihood of future recurrence.
At Spine Chiropractic, we provide evidence-informed chiropractic care for a wide range of musculoskeletal conditions that affect daily life, including:
