Here it is: # Dry Needling for Manual Therapists: Points, Techniques and Treatments, Including Electroacupuncture Dry needling is a technique that physical therapists and other trained healthcare providers use to treat musculoskeletal pain and movement issues. Its almost always used as part of a larger pain management plan that could include exercise, stretching, massage and other techniques. During this treatment, a provider inserts thin, sharp needles through your skin to treat underlying myofascial trigger points. Trigger points are knotted, tender areas that develop in your muscles. These trigger points are highly sensitive and can be painful when touched. Sometimes, a trigger point may be near the location of your pain. But theyre also often the cause of referred pain. Referred pain is pain that affects another part of your body. Dry needling can help reduce muscle tension, increase blood flow and decrease pain in the affected areas. It can also improve range of motion, function and quality of life for people with various musculoskeletal conditions. Dry needling is not the same as acupuncture. Although both techniques use needles to stimulate specific points in the body, they have different origins, theories and applications. Acupuncture is based on traditional Chinese medicine principles that aim to balance the flow of energy (qi) in the body. Dry needling is based on modern scientific research that focuses on treating neuromuscular dysfunction. In this article, we will explore the points, techniques and treatments of dry needling for manual therapists. We will also discuss electroacupuncture, a variation of dry needling that uses electrical stimulation to enhance its effects. ## Dry Needling Points Trigger points are the main targets of dry needling. They are defined as hyperirritable spots in skeletal muscle that are associated with a hypersensitive palpable nodule in a taut band. Trigger points can be classified into two types: active and latent. Active trigger points cause spontaneous pain or pain in response to movement or pressure. Latent trigger points do not cause pain unless they are stimulated by external factors. However, both types of trigger points can impair muscle function and contribute to chronic pain syndromes. Trigger points can be identified by palpation or by using diagnostic tools such as ultrasound or electromyography (EMG). Palpation involves feeling the muscle tissue with fingers or hands to locate any taut bands or nodules that elicit pain or twitching. Ultrasound can visualize the muscle structure and detect any changes in its shape or density. EMG can measure the electrical activity of the muscle and detect any abnormal patterns or signals. There are many trigger points in the human body, and they can vary depending on the individual, the condition and the muscle involved. Some of the common trigger points for different body regions and conditions are: - Neck: The upper trapezius, levator scapulae, sternocleidomastoid and scalene muscles are often involved in neck pain, headaches, whiplash and temporomandibular joint (TMJ) disorders. - Shoulder: The supraspinatus, infraspinatus, subscapularis and teres minor muscles are often involved in shoulder pain, impingement, rotator cuff injuries and frozen shoulder. - Back: The erector spinae, quadratus lumborum, multifidus and gluteus medius muscles are often involved in low back pain, sciatica, sacroiliac joint dysfunction and piriformis syndrome. - Hip: The gluteus maximus, gluteus minimus, tensor fasciae latae and iliopsoas muscles are often involved in hip pain, bursitis, osteoarthritis and snapping hip syndrome. - Knee: The vastus medialis, vastus lateralis, rectus femoris and biceps femoris muscles are often involved in knee pain, patellofemoral pain syndrome, iliotibial band syndrome and meniscus injuries. - Ankle: The gastrocnemius, soleus, tibialis anterior and peroneus longus muscles are often involved in ankle pain, sprains, plantar fasciitis and Achilles tendinitis. The selection of the appropriate needle size, length and gauge depends on several factors, such as the depth, location and size of the trigger point, the thickness of the skin and subcutaneous tissue, the sensitivity of the patient and the preference of the provider. Generally speaking, longer and thicker needles are used for deeper and larger trigger points, while shorter and thinner needles are used for superficial and smaller trigger points. Some examples of common needle sizes for different trigger points are: - Upper trapezius: 40 mm x 0.25 mm or 50 mm x 0.30 mm - Supraspinatus: 40 mm x 0.25 mm or 50 mm x 0.30 mm - Quadratus lumborum: 60 mm x 0.30 mm or 75 mm x 0.35 mm - Gluteus maximus: 60 mm x 0.30 mm or 75 mm x 0.35 mm - Vastus lateralis: 40 mm x 0.25 mm or 50 mm x 0.30 mm - Gastrocnemius: 40 mm x 0.25 mm or 50 mm x 0.30 mm ## Dry Needling Techniques The basic principles and steps of dry needling are: - Obtain informed consent from the patient and explain the procedure, benefits, risks and alternatives. - Perform a thorough assessment of the patient's history, symptoms, signs and functional limitations. - Identify the trigger points by palpation or other methods. - Prepare the equipment and materials needed for dry needling, such as needles, gloves, alcohol swabs, gauze pads, sharps container, etc. - Cleanse the skin over the trigger point with an alcohol swab. - Insert the needle through the skin into the trigger point using a quick thrust or a gentle push. - Manipulate the needle to elicit a local twitch response (LTR), which is a brief contraction of the muscle fibers around the needle. - Leave the needle in place for a few minutes or until the LTR subsides. - Remove the needle and apply pressure with a gauze pad to stop any bleeding. - Dispose of the needle in a sharps container. - Repeat the process for other trigger points as needed. - Reassess the patient's pain, range of motion and function after dry needling. - Provide post-treatment instructions and advice to the patient. There are different types of dry needling techniques that vary in terms of depth, duration and frequency of needle insertion and manipulation. Some of the common types are: - Deep dry needling: The needle is inserted deeper into the muscle tissue until it reaches the trigger point. The needle is manipulated to elicit a local twitch response (LTR), which is an involuntary spinal cord reflex in which the muscle fibers in the taut band of muscle contract. The LTR indicates that the needle has hit the right spot and helps release the tension and pain in the trigger point. This technique is more effective than superficial dry needling for treating chronic and deep-seated trigger points, but it may also cause more discomfort and soreness. - Pistoning or sparrow pecking: This technique involves inserting and withdrawing the needle repeatedly in a rapid motion over the trigger point. The needle does not stay inserted in the skin for long. The goal is to stimulate the nerve endings and blood vessels in the area and provoke multiple LTRs. This technique may be used for superficial or deep trigger points, depending on the depth of penetration. - Non-trigger point dry needling: This technique involves inserting needles into areas that are not trigger points, but are related to the pain or dysfunction of the patient. For example, needles may be inserted into acupuncture points, nerve roots, spinal segments, tendons, ligaments or fascia. The aim is to modulate the nervous system and influence the pain perception and inflammatory response of the patient. ## Dry Needling Treatments Dry needling can be used to treat a variety of musculoskeletal conditions that involve pain, stiffness, inflammation, weakness or dysfunction of muscles, joints or nerves. Some of the common conditions that may benefit from dry needling are: - Neck pain - Shoulder pain - Back pain - Hip pain - Knee pain - Ankle pain - Headaches - Migraines - Temporomandibular joint (TMJ) disorders - Fibromyalgia - Chronic fatigue syndrome - Tennis elbow - Golfer's elbow - Carpal tunnel syndrome - Plantar fasciitis However, dry needling is not suitable for everyone. There are some indications and contraindications that should be considered before applying dry needling to a patient. Some of the indications are: - Presence of active or latent trigger points that cause pain or impair function - Failure of other conservative treatments to resolve the condition - Patient's consent and willingness to undergo dry needling Some of the contraindications are: - Needle phobia or anxiety - Bleeding disorders or anticoagulant medication use - Skin infections or wounds in the area to be treated - Allergy to metal or latex - Pregnancy (especially in the first trimester) - Cardiac pacemaker or implantable defibrillator - Cancer or metastasis - Neurological disorders or impaired sensation The design of a treatment plan for dry needling depends on several factors, such as the diagnosis, severity and duration of the condition, the patient's goals and preferences, and the provider's experience and skills. A typical treatment plan may include: - Frequency: The number of sessions per week or month may vary depending on the patient's response and progress. Generally, more frequent sessions are needed at the beginning of the treatment and less frequent sessions are needed as the condition improves. A common frequency is once or twice a week for 4 to 6 weeks. - Duration: The length of each session may vary depending on the number and location of trigger points to be treated, as well as the patient's tolerance and comfort level. A common duration is 15 to 30 minutes per session. - Intensity: The intensity of dry needling may vary depending on the depth, gauge and manipulation of the needle, as well as the patient's sensitivity and pain threshold. A common intensity is moderate to high, aiming to elicit LTRs without causing excessive discomfort or adverse effects. - Combination: Dry needling is usually combined with other manual therapy modalities, such as massage, mobilization, stretching, exercise, heat, ice, electrical stimulation, etc. The combination of modalities may enhance the effects of dry needling by increasing blood flow, reducing inflammation, relaxing muscles, improving mobility and function, and preventing recurrence. ## Electroacupuncture Electroacupuncture is a variation of dry needling that uses electrical stimulation to enhance its effects. Electroacupuncture involves attaching electrodes to two or more needles that are inserted into the trigger points or related areas. A low-frequency electrical current is then applied to the needles, causing them to vibrate and stimulate the muscle fibers and nerve endings. Electroacupuncture has some advantages and disadvantages compared to dry needling alone. Some of the advantages are: - It can elicit stronger and more sustained LTRs, which may result in more pain relief and muscle relaxation. - It can reduce the need for manual manipulation of the needle, which may reduce the provider's fatigue and the patient's discomfort. - It can treat multiple trigger points or areas simultaneously, which may save time and increase efficiency. Some of the disadvantages are: - It may cause more adverse effects, such as bleeding, bruising, infection, nerve damage, muscle damage, or cardiac arrhythmia. - It may require more equipment and training, which may increase the cost and complexity of the treatment. - It may be contraindicated for patients with pacemakers, defibrillators, metal implants, epilepsy, or pregnancy. The application of electroacupuncture requires careful consideration of the parameters of the electrical stimulation, such as frequency, intensity, duration, polarity, waveform, etc. These parameters may affect the outcome and safety of the treatment. Some of the common parameters are: - Frequency: The number of pulses per second (Hz) that are delivered to the needles. Lower frequencies (1 to 4 Hz) tend to produce more analgesic effects, while higher frequencies (50 to 100 Hz) tend to produce more muscle relaxation effects. A combination of low and high frequencies (2/100 Hz) may produce both effects. - Intensity: The amount of current (mA) that flows through the needles. Higher intensities tend to produce stronger LTRs and more pain relief, but they may also cause more discomfort and adverse effects. The intensity should be adjusted according to the patient's tolerance and comfort level. A common range is 0.5 to 4 mA. - Duration: The length of time (min) that the electrical stimulation is applied to the needles. Longer durations tend to produce more lasting effects, but they may also increase the risk of adverse effects. The duration should be determined by the patient's response and progress. A common range is 10 to 30 minutes per session. - Polarity: The direction of current flow between the positive (+) and negative (-) electrodes attached to the needles. The polarity may affect the biochemical and physiological responses of the tissue and nerve cells. Some studies suggest that positive polarity may have more anti-inflammatory effects, while negative polarity may have more analgesic effects. However, more research is needed to confirm this hypothesis. A common practice is to alternate polarity every 5 minutes during a session. - Waveform: The shape of the electrical signal that is delivered to the needles. Different waveforms may have different effects on the tissue and nerve cells. Some of the common waveforms are: - Monophasic: The current flows in one direction only, either positive or negative. - Biphasic: The current flows in both directions, alternating between positive and negative. - Pulsed: The current flows in bursts or pulses, with intervals of no current in between. - Continuous: The current flows without interruption or variation. A common waveform for electroacupuncture is biphasic pulsed current, which mimics the natural electrical activity of nerve cells and muscles. ## Conclusion Dry needling is a valuable technique for manual therapists who want to treat musculoskeletal pain and dysfunction caused by trigger points and related conditions.
