Dry needling for scar treatment.

OBJECTIVE: To review current scientific knowledge as to the efficacy of dry needling of scars on pain and other related symptoms and explore the possible physiological mechanisms of action. METHODS: A narrative review of scientific literature published in English. RESULTS: Two randomized controlled trials found that dry needling of scars (using the classic "surrounding the dragon" technique in one study and intradermal needling in a second study) was more effective than sham or control interventions with respect to scar appearance and pain. Two case reports have suggested that scar needling generates a rapid decrease in pain and improvement of mobility in scarred tissues. Another two case reports have reported positive effects of scar needling on the wound healing process. These findings are supported by an animal study examining the effect of needling on the wound healing process and the physiological mechanisms of action underlying the technique. CONCLUSION: There is preliminary evidence that the "surrounding the dragon" needling technique is a beneficial treatment for patients suffering from scar pain and other scar-related symptoms and can facilitate wound healing and make this process less painful. Further high-quality studies should be conducted to verify/quantify the efficacy of this method, to better understand the underlying mechanisms of action underlying the effects of scar needling and to establish an effective intervention protocol.

The prevalence of myofascial trigger points in hip and thigh areas in anterior knee pain patients.

BACKGROUND: Anterior knee pain (AKP) is a widespread problem among young athletes and soldiers. There are many theories on the etiology of AKP but there is little reference to myofascial trigger points (MTrPs) as a possible contributor. AIM: To evaluate the association between AKP and prevalence of active and latent MTrPs in the hip and thigh muscles in soldiers. METHODS: A cross-sectional study was conducted in the Beer-Sheva military outpatient physical therapy clinic. Subjects were 42 men and 23 women referred for physical therapy, 33 with a diagnosis of AKP (cases) and 32 with upper limb complaints (without AKP, controls). All subjects underwent physical evaluation by an examiner blinded to their identity and medical condition. The following muscles were assessed bilaterally for active or latent MTrPs: rectus femoris (proximal), vastus medialis (middle and distal), vastus lateralis (middle and distal) and gluteus medius (anterior, posterior and distal). RESULTS: In six out of eight areas, the cases had a higher prevalence of total active and latent MTrPs than the controls. When summarizing MTrPs by muscle, cases had significantly more MTrPs than controls in each muscle. The largest difference was found in vastus medialis and vastus lateralis; nearly half of the cases had MTrPs in these muscles. CONCLUSIONS: Subjects with AKP have a greater prevalence of MTrPs in their hip and thigh muscles than controls, indicating an association between MTrPs and AKP. Further research is necessary to determine whether MTrPs are the cause or the consequence of AKP.

New is the well-forgotten old: The use of dry cupping in musculoskeletal medicine.

Cupping is an ancient technique used in treating pain and various disorders. Different techniques have been developed over time, however, applying a cup to create suction over a painful area, is common to all. Dry or fire cupping, used on the intact skin, leaves bluish circular hematomas. Recently, interest in cupping has re-emerged and subsequently, several studies have begun to investigate the mechanisms of cupping therapy. Mechanically, cupping increases blood circulation, whereas physiologically it activates the immune system and stimulates the mechanosensitive fibers, thus leading to a reduction in pain. There is initial scientific evidence that dry cupping is able to reduce musculoskeletal pain. Since cupping is an inexpensive, noninvasive and low-risk (if performed by a trained practitioner) therapeutic modality, we believe that it should be included in the arsenal of musculoskeletal medicine. It is essential to perform additional studies clarifying the biological mechanism and clinical effects of cupping.
