Chiropractic Adjustment: Procedure, Benefits, Risks, Recovery and Alternatives

Chiropractic adjustment, often called spinal manipulation, is a widely used manual therapy approach aimed at improving musculoskeletal health. Whether you're managing chronic back pain, seeking to enhance mobility, or simply curious about alternative therapies, understanding what a chiropractic adjustment involves, its potential benefits and risks, and what to expect during recovery is vital. This article explores these aspects in depth, providing an evidence-based overview to help you make informed decisions.

Chiropractic Adjustment: The Procedure

Chiropractic adjustment is a hands-on technique primarily targeting the spine but can also be applied to other joints. The aim is to restore normal function, alleviate discomfort, and promote overall well-being. These procedures vary in technique, force, and focus, depending on the patient's condition and the chiropractor's expertise.

Technique	Approach	Indication	Source
High Velocity, Low Amplitude (HVLA)	Quick, controlled thrust	Low back pain, joint dysfunction	1, 2, 5
Mechanical/Instrument-assisted	Device delivers impulse	Sacroiliac/coccyx issues, gentle option	3, 5
Mobilization	Gentle, non-thrust	Neck pain, mild stiffness	2, 11
Traction/Soft tissue	Stretching, muscle work	Muscle tightness, joint restriction	2

Table 1: Overview of Common Chiropractic Procedures

Types of Chiropractic Adjustments

Chiropractors use a variety of adjustment techniques, tailored to the patient's needs:

• High-Velocity, Low-Amplitude (HVLA) Thrusts: This classic technique involves a rapid, targeted movement to a specific joint, often resulting in a popping sound. It is most commonly used for low back pain and has the broadest evidence base for effectiveness 1, 2.
• Instrument-Assisted Adjustments: Devices such as the Activator Adjusting Instrument deliver a precise, controlled force to a joint. These are especially useful for patients requiring a gentler approach or for regions like the coccyx 3, 5.
• Mobilization: Unlike HVLA, mobilization employs slow, controlled movements to increase joint range of motion, commonly used for neck pain or when manipulation is contraindicated 2, 11.
• Soft Tissue and Traction Procedures: These involve stretching muscles and ligaments or applying traction to relieve tension and improve mobility 2.

The Chiropractic Session

A typical chiropractic session begins with a detailed assessment, including a physical exam and sometimes diagnostic imaging, to evaluate joint function and rule out contraindications 2. The actual adjustment is usually performed with the patient lying, sitting, or standing, depending on the technique and area being treated 2. Some cases may require modifications, especially if contraindications exist.

Indications and Contraindications

Chiropractic adjustments are primarily indicated for musculoskeletal pain—especially low back pain, neck pain, headaches, and certain joint dysfunctions 1, 4. However, care is taken to screen for contraindications such as severe osteoporosis, acute fractures, or certain vascular disorders 2. In some cases, techniques may be modified to accommodate the patient's health status.

Benefits and Effectiveness of Chiropractic Adjustment

Chiropractic adjustments are commonly sought for their potential to reduce pain, improve mobility, and enhance quality of life. Recent research supports several specific benefits, although results can vary based on the technique used and the condition treated.

Benefit	Evidence Level	Application	Source
Pain Reduction	Strong	Low back, sacroiliac, subacute pain	1, 4, 5, 6
Improved Function	Moderate	Spinal, extremity joints	1, 5, 8
Central Pain Processing	Emerging	Potential neural modulation	7
Benefits in Asymptomatic Individuals	Preliminary	General wellness	8

Table 2: Key Benefits of Chiropractic Adjustment

Pain Relief and Functional Improvement

• Low Back Pain: Multiple systematic reviews and clinical trials indicate that chiropractic adjustment, particularly HVLA side-posture manipulation, is effective for reducing low back pain and improving function 1, 4, 5, 6.
• Sacroiliac Joint and Coccyx Issues: Both manual and instrument-assisted adjustments show significant improvements in pain and disability for conditions like sacroiliac syndrome and coccygodynia 3, 5.
• Neck Pain: Chiropractic can reduce neck pain, though some studies suggest mobilization may yield comparable results with fewer adverse reactions 11.

Impact on Central Nervous System

• Preliminary research suggests chiropractic spinal adjustments may modulate pain perception and central nervous system activity, potentially altering how the brain processes persistent pain signals 7.

Effects in Asymptomatic Individuals

• Some objective studies report measurable physiologic changes—such as improved joint function and potential systemic benefits—even in individuals without symptoms, though more research is needed to confirm long-term effects 8.

Comparative Effectiveness

• In head-to-head studies, chiropractic adjustments have performed as well as or better than muscle relaxants for subacute low back pain, especially in terms of pain reduction and global clinical improvement 4.
• Manual and instrument-assisted techniques appear similarly effective for many musculoskeletal complaints 5.

Risks and Side Effects of Chiropractic Adjustment

While chiropractic adjustment is generally regarded as safe, especially when performed by trained professionals, it is not without risks. Understanding the potential side effects—from mild discomfort to rare but serious complications—is crucial for informed decision-making.

Risk/Side Effect	Frequency	Severity	Source
Minor (pain, headache, dizziness)	Common (30–60%)	Mild/Transient	10, 11, 12
Serious (stroke, myelopathy)	Very rare (1–6/100,000 to 2–3/10M)	Severe/Potentially Life-Threatening	9, 10, 12, 13
Adverse with Manipulation vs Mobilization	Higher with manipulation	Mild–Moderate	11

Table 3: Adverse Events Associated with Chiropractic Adjustment

Common Side Effects

• Most patients experience mild, self-limiting symptoms such as increased pain, headache, fatigue, or dizziness after an adjustment. These effects typically resolve within a few days 10, 11, 12.
• The risk of minor adverse events is higher after cervical spine manipulation than after gentler mobilization techniques 11.

Serious Risks

• Neurologic Complications: Rare but serious events include stroke (most often from vertebral artery dissection), myelopathy, and radiculopathy, particularly after cervical (neck) manipulation 9, 12, 13.
  • The estimated risk of serious complications ranges from 1 in 100,000 to 1 in several million manipulations 10, 12.
  • Most patients who experience these complications have no identifiable risk factors beforehand 13.

Risk Mitigation

• Chiropractors are trained to assess for contraindications and modify techniques as needed to minimize risk 2.
• Patients are encouraged to discuss any pre-existing health conditions and to seek immediate care if they experience unusual symptoms after an adjustment.

Recovery and Aftercare of Chiropractic Adjustment

Proper recovery and aftercare can maximize the benefits of chiropractic adjustments and minimize discomfort. While most people resume normal activities immediately, some may require additional support.

Recovery Time	Common Aftercare	When to Seek Help	Source
Immediate to 48 hours	Ice/heat, hydration, gentle movement	Severe pain, neurologic symptoms	2, 10, 11
Minor Soreness	Yes (resolves quickly)	If worsening/persistent	10, 11
Activity Modification	Rarely needed	As advised by practitioner	2

Table 4: Recovery and Aftercare Considerations

Typical Recovery Experience

• Most patients can return to everyday activities immediately after a chiropractic session.
• It's common to feel mild soreness or achiness, similar to what you might experience after exercise. This usually fades within 24–48 hours 10, 11.

Aftercare Recommendations

• Apply Ice or Heat: To ease any discomfort, use ice packs or gentle heat as recommended by your chiropractor 2.
• Stay Hydrated: Drinking water can help flush metabolic byproducts released during adjustment.
• Gentle Movement: Light stretching or walking can help maintain mobility.

When to Contact Your Provider

• Seek prompt medical attention if you experience severe pain, numbness, weakness, dizziness, or any symptoms suggesting neurologic compromise after an adjustment 10, 13.

Follow-up and Monitoring

• Some conditions may require a series of adjustments for optimal results. Your chiropractor will usually recommend a follow-up plan based on your progress and any ongoing symptoms 2.

Alternatives of Chiropractic Adjustment

While chiropractic adjustment is a popular choice for musculoskeletal complaints, it is not the only option. Understanding alternatives can help you make the best choice for your specific needs and preferences.

Alternative	Approach/Modality	Indications	Source
Physical Therapy	Exercise, manual therapy	Pain, rehabilitation	4, 12
Medication	NSAIDs, muscle relaxants	Acute/subacute pain	4
Mobilization	Gentle, non-thrust manipulation	Neck/back pain	2, 11
Acupuncture	Needle stimulation	Chronic pain, wellness	12

Table 5: Common Alternatives to Chiropractic Adjustment

Physical Therapy

Physical therapists use tailored exercise programs, manual therapy, and modalities like ultrasound or electrical stimulation to restore function and relieve pain. It's especially valuable for rehabilitation after injury or surgery.

Medications

For acute or subacute musculoskeletal pain, medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants may be prescribed. In comparative studies, chiropractic adjustments have shown similar or better efficacy for certain back pain conditions 4.

Mobilization

Mobilization involves gentle, non-thrust movements and may be preferred for patients who are at higher risk of adverse events from manipulation, or those with mild symptoms 2, 11.

Other Complementary Therapies

Options such as acupuncture, massage therapy, and yoga are also used for musculoskeletal pain and general wellness. The evidence for these therapies varies, but they may be beneficial for some individuals 12.

Conclusion

Chiropractic adjustment is a well-established therapeutic option for musculoskeletal pain, particularly for the spine. Like all medical interventions, it comes with benefits and risks. Being informed about the procedure, expected outcomes, potential side effects, and alternatives empowers you to make the best choices for your health and well-being.
