Do You Experience Any of These Symptoms?
- Lower back pain after sitting for long periods
- Chronic lower back pain that has lasted for months or years
- Back pain that interferes with your work
- Stiffness that improves temporarily after stretching
- Lower back pain that returns shortly after massage or manual therapy
- Back pain that is worse during office work but improves when walking
- Persistent lower back discomfort despite normal X-rays or medical examinations
- Looking for long-term relief rather than temporary pain relief
If these symptoms sound familiar, you may be experiencing chronic mechanical lower back pain rather than a serious spinal disorder.
Many people assume that chronic lower back pain originates solely from the lumbar spine. However, prolonged sitting, poor posture, pelvic dysfunction, reduced hip mobility, and muscle imbalance frequently contribute to persistent symptoms.
This case report describes an office worker whose 10-year history of chronic lower back pain significantly improved after a comprehensive biomechanical assessment and individualized chiropractic care.
A man in his 30s working in the Kannai business district of Yokohama visited Spine Chiropractic with persistent lower back pain that had gradually worsened over more than ten years.
His symptoms first began shortly after starting a full-time office job in his twenties.
Initially, the discomfort occurred only during working hours and disappeared after returning home or during weekends. Because the pain was temporary, he did not seek professional treatment.
Over the following decade, however, the condition gradually progressed.
By his mid-thirties, the pain was no longer limited to work. Instead, he experienced constant stiffness and discomfort throughout the day, with the pain predominantly affecting the right side of his lower back.
As an office worker, he spent most of his day sitting at a computer.
The pain frequently interrupted his concentration, forcing him to stand up regularly, stretch, and rotate his lower back simply to continue working.
Following the COVID-19 pandemic, his company introduced a hybrid work schedule.
Interestingly, although he believed working from home reduced his overall activity level, he found that his symptoms were often less severe because he could stand, stretch, and move around whenever necessary.
When working in the office, however, prolonged uninterrupted sitting consistently aggravated his symptoms.
Over the years, he had consulted several healthcare providers, including orthopedic clinics, massage therapists, and manual therapy practitioners.
Massage therapy usually provided temporary relief, but the improvement rarely lasted longer than a week before the pain returned.
Having become frustrated with short-term symptom relief, he began searching for a clinic that could identify the underlying cause of his chronic lower back pain rather than simply treating the symptoms.
This led him to Spine Chiropractic, conveniently located one minute from Bashamichi Station in central Yokohama.
[Initial Symptoms]
- Patient History:
The patient had experienced chronic lower back pain for over ten years.
During that time, he had visited orthopedic clinics, osteopathic clinics, massage therapists, and chiropractic clinics.
Among these treatments, he recalled experiencing the greatest improvement after receiving manual therapy at a previous clinic before relocating to Yokohama.
Although the pain always returned eventually, the symptom-free period became noticeably longer after treatment.
Following his relocation, however, he was unable to find a clinic that produced comparable results and continued searching for an effective long-term solution.
He also reported several characteristic features of his pain:
- Pain increased during prolonged sitting.
- Standing up and walking temporarily relieved the discomfort.
- Stretching or rotating the lower back reduced symptoms for a short period.
- Rest alone did not completely eliminate the pain.
These findings suggested that the patient’s symptoms were more consistent with mechanical dysfunction involving the lumbar spine, pelvis, and hips rather than inflammatory or neurological disease.
- Postural Assessment
Postural observation revealed a pronounced slouched sitting posture.
The pelvis rested in excessive posterior tilt, and the normal lumbar lordosis was almost completely absent while seated.
This posture significantly increased mechanical loading on the lumbar spine during prolonged desk work.
A forward head posture and mild thoracic kyphosis were also observed, further contributing to poor spinal biomechanics.
- Static Palpation:
Palpation demonstrated increased muscle tension throughout the lumbar paraspinal muscles, particularly involving the:
- Erector spinae
- Quadratus lumborum
- Multifidus
Marked asymmetry was present, with considerably greater muscle tightness on the right side.
The lumbar musculature showed signs of chronic overload consistent with prolonged postural stress.
- Motion Palpation:
Motion palpation revealed functional joint restriction involving the right sacroiliac joint.
Posterior dysfunction of the right SI joint reproduced the patient’s familiar pain during palpation.
Restricted motion was also identified at the L5 vertebra, with right rotational dysfunction producing localized tenderness during left-to-right spring testing.
Assessment of the hips demonstrated significant asymmetry in range of motion.
The right hip showed noticeably reduced mobility compared with the left, increasing compensatory movement demands on the lumbar spine during daily activities.
Although trunk flexion, extension, lateral bending, and rotation appeared relatively preserved, prolonged static sitting consistently increased mechanical stress across the lumbopelvic region.
- Orthopedic Tests:
A comprehensive orthopedic examination was performed to exclude serious spinal pathology.
Multiple orthopedic tests, including Adam’s Forward Bend Test, were negative.
Neurological screening demonstrated no evidence of lumbar disc herniation, nerve root compression, or other significant neurological disorders.
The patient’s symptoms were therefore considered most consistent with chronic mechanical lower back pain associated with postural dysfunction and impaired joint mechanics.
- Muscle Strength Examination:
Manual muscle testing identified mild weakness involving:
- Left gluteal muscle group (4/5)
- Right iliopsoas muscle (4/5)
Reduced strength in these stabilizing muscles likely contributed to decreased pelvic stability and increased mechanical loading of the lumbar spine.
Overall, the assessment indicated that the patient’s symptoms were not caused by structural damage alone.
Instead, they resulted from a combination of prolonged desk work, poor posture, impaired lumbar and pelvic joint mechanics, restricted hip mobility, and muscular imbalance—factors commonly associated with chronic lower back pain in office workers.
[Initial Treatment Plan]
Based on the examination findings, we concluded that the patient’s symptoms were not caused by the lumbar spine alone.
Instead, his chronic lower back pain appeared to result from a combination of prolonged sitting, poor posture, pelvic dysfunction, reduced hip mobility, and muscular imbalance that had gradually developed over more than ten years.
Rather than focusing solely on the painful area, treatment was directed toward restoring normal movement throughout the lumbopelvic region and correcting the underlying biomechanical dysfunction.
Treatment began with interferential current therapy to reduce excessive muscle tension in the lumbar erector spinae, quadratus lumborum, gluteal muscles, and surrounding soft tissues.
While receiving therapy, the patient performed gentle, pain-free pelvic and hip movements to improve neuromuscular coordination instead of simply relaxing the muscles.
This approach helps restore normal muscle recruitment patterns and encourages more efficient spinal movement.
Following this, instrument-assisted soft tissue mobilization (IASTM) was performed to improve soft tissue mobility throughout the lumbar region, gluteal muscles, and posterior hip musculature.
Years of prolonged sitting had reduced tissue flexibility around the pelvis and hips, increasing mechanical stress on the lower back.
Improving soft tissue mobility helped reduce this excessive loading.
A comprehensive biomechanical reassessment identified functional joint dysfunction involving the:
- Right sacroiliac joint
- Fifth lumbar vertebra (L5)
- Right hip
- Thoracolumbar junction
These regions demonstrated restricted movement patterns commonly associated with prolonged desk work and chronic lower back pain.
Specific chiropractic adjustments were therefore applied to restore normal joint mobility and improve overall spinal biomechanics.
Finally, the patient received individualized advice regarding long-term prevention, including:
- Proper sitting posture during desk work
- Pelvic positioning while sitting
- Hip mobility exercises
- Gluteal and iliopsoas strengthening
- Standing and walking briefly at least once every hour
The goal was not only to reduce pain but also to minimize the likelihood of recurrence.
[Treatment Progress]
First Visit
Immediately following the initial treatment, the patient reported a noticeable reduction in lower back tightness.
His sitting posture improved naturally, and movement of the pelvis felt significantly easier.
He commented,
“My back already feels lighter, and I’m sitting much straighter without trying.”
Because the symptoms had persisted for more than ten years, we explained that long-term improvement would require restoring normal movement patterns rather than simply relieving pain.
A follow-up visit was scheduled one week later.
Second Visit (One Week Later)
At his second appointment, the patient reported that he was thinking about his lower back far less during work.
Previously, he had needed to stand up and stretch frequently throughout the day.
After only one treatment, the number of interruptions had decreased considerably.
Although mild discomfort remained after prolonged sitting, his overall symptoms had improved by approximately 70% compared with his initial visit.
Treatment continued with additional emphasis on improving hip mobility, pelvic stability, and activation of the gluteal musculature to further reduce mechanical stress on the lumbar spine.
Fourth Visit
By the fourth treatment, the patient was able to complete a full workday with little awareness of his lower back.
He no longer needed to rely on frequent stretching throughout the day and reported being able to concentrate more effectively at work.
Weekend massage appointments were no longer necessary because the pain did not return as it had previously.
Reassessment demonstrated significant improvements in posture, pelvic mechanics, hip mobility, and muscle function compared with the initial examination.
Sixth Visit
After six treatments, the patient’s chronic lower back pain had largely resolved.
He was able to perform both office work and daily activities without significant discomfort.
Given that his occupation still involved prolonged sitting, we recommended transitioning to monthly maintenance chiropractic care to help maintain spinal function, reduce the risk of recurrence, and support long-term musculoskeletal health.
Before discharge, the patient shared the following feedback:
“Massage always made me feel better temporarily, but the pain kept coming back. This time, I can finally work without constantly thinking about my lower back. I wish I had come here much sooner.”
[Practitioner’s Opinion]
Can chronic lower back pain improve without treatment?
Some episodes of lower back pain may improve naturally. However, if symptoms persist for months or years, underlying biomechanical dysfunction often remains uncorrected, increasing the likelihood of recurring pain.
Can chiropractic care help desk job-related lower back pain?
Yes. Many office workers develop chronic lower back pain due to prolonged sitting, poor posture, reduced hip mobility, and muscular imbalance. Chiropractic care aims to restore normal joint function and improve movement patterns contributing to these symptoms.
How is chiropractic different from massage therapy?
Massage therapy primarily focuses on reducing muscle tension.
Chiropractic care evaluates not only muscles but also spinal and joint mobility, posture, biomechanics, and neuromuscular function to identify and address contributing factors associated with persistent pain.
Do I need an MRI for chronic lower back pain?
Not always.
If symptoms include progressive muscle weakness, significant numbness, bowel or bladder dysfunction, or other neurological signs, medical imaging may be recommended.
However, many patients with chronic mechanical lower back pain have normal MRI or X-ray findings despite experiencing persistent symptoms.
How many treatments will I need?
The number of treatments varies depending on the severity, duration, and underlying cause of the condition.
For chronic lower back pain, we commonly begin with weekly visits and gradually increase the interval between appointments as spinal function improves and symptoms stabilize.
