Dry Needling vs. Acupuncture: Choosing The Right Option

Dry needling

Dry needling is a therapeutic technique used by physiotherapists to reduce severity of pain and improve musculoskeletal functions. It involves the skilled insertion of a thin, sterile needle into specific points within muscles often referred to as trigger points or myofascial trigger points.

The aim of dry needling is to target and release these trigger points, which are often associated with tightness, muscle knots, and pain. The trigger points is stimulated with the help of needle, thus releasing tension and promoting muscle relaxation. Physiological responses like increased blood flow, reduced pain sensitivity, and improved range of motion is also achieved.

 

Conditions Treated with Dry Needling

• Musculoskeletal Pain: Including back pain, neck pain, shoulder pain, and joint pain.
• Myofascial Pain Syndrome: Characterized by trigger points or muscle knots.
• Sports Injuries: Such as muscle strains, ligament sprains, and overuse injuries.
• Tension Headaches and Migraines: Targeting muscle tension contributing to headaches.
• Neuropathic Pain: Including conditions like sciatica or carpal tunnel syndrome.
• Fibromyalgia: For pain relief and muscle relaxation.
• Post-Surgical Pain: To manage pain and promote recovery.
• Chronic Pain: Associated with various conditions, including arthritis and nerve compression.

 

Techniques of Dry Needling

Myofascial Trigger Point (MTrPs) Dry Needling:

This is the most frequently used technique, in this procedure the needle is inserted directly into a myofascial trigger point (a tight band or knot in a muscle). The aim is to release tension and alleviate pain in the affected muscle.

MTrPs can be categorized into two types, latent and active. It is important to distinguish between the these two types. It it is latent MTrPs it exacerbate pain when the dry needle is inserted or direct pressure is applied. On the other hand if the MTrPs is active it will cause symptoms at rest or during activity.

A common response seen during this technique is twitch response i.e. a brief, involuntary contraction of the muscle. It helps the physiotherapist make assumption that the needle has reached the trigger point.

 

Superficial Dry Needling: 

In this technique, the needle is inserted superficially below the skin's surface, it targets superficial muscle layers and fascia. It's often used for conditions where deep needling might not be recommended.

Superficial dry needling is believed to have following benefits:

• Local blood flow improvement
• Sensory stimulation
• Relaxation of superficial muscle tension

Deep Dry Needling: 

This technique involves inserting the needle into the  deep muscle tissue so the trigger points or tight bands can be located. It's advisable used for chronic and deeper-seated muscular issues.

 

Intramuscular Stimulation (IMS): 

IMS is a dry needling technique that focuses on treating neuromuscular conditions. It's aim is to stimulate and reset dysfunctional nerve pathways that may be causing pain or muscle dysfunction. The physiotherapist will notice twitch response accompanied by relaxation response indicating that the muscle is responding to the treatment.

 

Paraspinal Dry Needling: 

In this technique the paraspinal muscles are targeted along the spine. It helps with spinal conditions or posture-related issues for example chronic back pain, muscle spasms, postural issues, and issues with spinal stability.

Segmental Dry Needling: 

Segmental dry needling focuses on specific spinal segments and related muscle groups. It's often used in cases of referred pain or when there is dysfunction associated with specific spinal levels.

 

Motor Point Dry Needling: 

This technique targets motor points, which are specific areas within muscles where the nerve enters the muscle. It's used to enhance muscle function and can be beneficial for athletes and individuals with muscle imbalance.

 

Acupuncture

Acupuncture. not directly related to physiotherapy, has been practiced for centuries. The  origination is from traditional Chinese medicine. It is often regulated as a separate complementary or alternative therapy.

Acupuncture also involves the insertion of thin, sterile needles into specific points on the body known as acupuncture points or meridians. These points are believed to be connected through energy pathways, or meridians, which are associated with the flow of vital energy, called "Qi" (pronounced "chee"), in traditional Chinese medicine.

 

Conditions Treated with Acupuncture

• Pain Management: Including chronic pain conditions, headaches, and migraines.
• Stress and Anxiety: To promote relaxation and emotional well-being.
• Depression: As a complementary therapy for managing symptoms.
• Sleep Disorders: To improve sleep quality and address insomnia.
• Digestive Disorders: Such as irritable bowel syndrome (IBS) and indigestion.
• Respiratory Conditions: Including asthma and allergies.
• Fertility and Reproductive Health: To address conditions like infertility and menstrual irregularities.
• Neurological Disorders: Such as neuropathy and multiple sclerosis.
• Addiction: As part of addiction recovery programs.
• Immune System Support: To enhance the body's overall immune function.
• Side Effects of Cancer Treatment: To alleviate nausea, pain, and fatigue in cancer patients.
• Skin Conditions: Such as eczema and psoriasis.
• Menopausal Symptoms: Including hot flashes and mood swings.
• Hypertension: As part of a holistic approach to managing blood pressure.

 

Techniques of Acupuncture

Traditional Acupuncture: 

This is the most widely used form of acupuncture and involves the insertion of fine needles into specific acupuncture points on the body. These points are determined based on traditional Chinese medicine principles and the patient's specific condition.

 

Electroacupuncture: 

This technique involves attaching electrodes to acupuncture needles to provide a small electrical impulse. It is thought to enhance the stimulation of acupuncture points and is often used for pain management and certain neurological conditions. It can be used as an alternative mode of treatment for electrotherapy along with use of certain drugs like NSAIDs.

 

Auricular Acupuncture: 

Also known as ear acupuncture, this technique focuses on acupuncture points located on the ear. It is often used for various conditions, including addiction treatment, pain management, and stress reduction.

 

Scalp Acupuncture: 

Scalp acupuncture involves the insertion of needles into specific points on the scalp. It is commonly used for neurological conditions, such as stroke recovery and paralysis.

 

Comparison of Dry Needling and Acupuncture

 

Dry Needling Vs Acupuncture For Plantar Fasciitis

Dry needling for plantar fasciitis focuses on muscular tightness and trigger points. Acupuncture, on the other hand, takes a more holistic approach, potentially helping with pain management and overall well-being.

Dry Needling for Plantar Fasciitis:

Dry needle is directly inserted into trigger points within the affected muscles and fascia. It targets trigger points and myofascial restrictions in the calf muscles, Achilles tendon, and the plantar fascia itself. It is effective in addressing muscular imbalances and tightness that contribute to plantar fasciitis.

It can be combined with other physiotherapy techniques such as stretching and strengthening exercises for a comprehensive approach.

Acupuncture for Plantar Fasciitis:

It may be beneficial for managing the stress and anxiety that is associated with chronic conditions like plantar fasciitis.

  

Dry Needling vs Acupuncture for Sciatica

More evidence is found on positive outcome of acupuncture for sciatica as compared to dry needling. Dry needling is highly specific and targets the muscles and soft tissues that may be contributing to sciatic nerve compression.

Acupuncture for Sciatica:

Acupuncture promotes analgesic effect in patients with sciatica that can be explained by Segmental Inhibitory mechanisms. It is the neural processes that control and modulate the activity of neurons within a specific segment or region of the nervous system, typically within the spinal cord or brainstem. These mechanisms play a crucial role in regulating the excitability of neurons and are essential for maintaining proper functioning of the nervous system.

How segmental inhibitory mechanisms relates to acupuncture:

• Local Segmental Effects: 

Acupuncture points can be located near nerves and muscles. The insertion of acupuncture needles at these points can stimulate local sensory receptors, including those that transmit pain signals. The activation of sensory receptors can trigger segmental inhibitory mechanisms in the spinal cord, leading to the release of endorphins and other neurotransmitters that help reduce pain perception.

• Neurotransmitter Release: 

Acupuncture promotes the release of inhibitory neurotransmitters such as endorphins, serotonin, and gamma-aminobutyric acid (GABA). These neurotransmitters can dampen the activity of pain-transmitting neurons and promote relaxation.

• Descending Inhibition: 

Acupuncture also influence descending inhibitory pathways from the brainstem and higher brain centers. The brain can send signals that modulate pain perception and reduce pain sensitivity. It facilitate this process by activating certain brain regions.

Role of GB and BL meridians for treating sciatica:

Gallbladder (GB) Meridian:

It is linked to issues such as headaches, migraines, eye problems, and emotional challenges related to decision-making and courage.

Bladder (BL) Meridian:

It is associated with issues related to fluid retention, urinary problems, and lower back pain. Acupuncture is employed to address these imbalances and promote better fluid regulation and overall well-being.
