Background and Objective: Trigger point is a hypersensitive spot in a taut band of skeletal muscles, it has intense pain while compression, producing movement and any alterations. Trapezius is the common muscle always develop trigger point, although various management exist in managing the trigger point still there are lot of scope in the research. So far, there are no studies on combining IRR with ischemic compression. The objective of the study was to identify the effect of ischemic compression and infrared radiation on myofascial trigger point of trapezius muscle with neck pain patients. Material and Methods: 60 patients were included for the study using experimental study design, they were recruited following due consideration of the selection criteria. First group is an experimental group, which receives IRR along with Ischemic compression therapy for 20 minutes. Second group is control group receives only IRR with gentle neck stretches for 20 minutes. All patient was advised to follow home advices and instructions given by the therapist through the period of the treatment. Written consent was obtained from every individual participant. The study duration was six months and the individual patient underwent 8 weeks. Study identifies two measures as an outcome, which are pain using numerical pain scale and trigger using pressure pain threshold. Results: Blinded assessor is used to identify the data’s collected from the patient during the initial visit and at the last visit by the participant. All the collected data were analyzed using SPSS 20.0. The result of the study shows that pain scale was 9.72 (p<0.001) and PPT was 12.25 (p<0.001). Conclusion: This study concluded that ischemic compression with infrared radiation therapy in myofascial trigger point of trapezius muscle in neck pain patients and it also significantly reduces the pain as well as the Pressure pain threshold.

Abstract The purpose was to determine the efficacy of deep dry needling (DDN) applied on an active myofascial trigger point (MTrP) versus a latent-MTrP versus a non-MTrP location, on pain reduction and cervical disability, in patients with chronic neck pain. A randomized, double-blind clinical trial design was used. A sample of 65 patients was divided into non-MTrP-DDN, active-MTrP-DDN and latent-MTrP-DDN groups. The visual analog scale (VAS), reproduction of the patient’s pain, number of local twitch responses, pressure pain threshold (PPT) and Neck Disability Index (NDI) were assessed before, during and after the intervention and up to 1 month post-intervention. The active-MTrP-DDN-group reduced pain intensity more than non-MTrP-DDN-group after a week and a month (p<0.01). Active-MTrP-DDN-group showed the greatest improvement in tibialis muscle PPT. An association was found with a higher percentage of subjects in whom their neck pain was reproduced when the active-MTrP (77.3%) and the latent-MTrP (81.8%) were treated. The application of DDN on an active-MTrP in the upper trapezius muscle shows greater improvements in pain intensity after one week and one month post-intervention, as well as lesser improvement in PPT in the tibialis muscle, compared to DDN applied in latent-MTrPs or outside of MTrPs in patients with neck pain

The Subject

Cutaneous pain thresholds were determined on blackened skin of foreheads and forearms of human subjects over areas of 16 cm2 by recording skin temperature during exposure to thermal radiation for periods up to 50 min. Intensity of stimulus was controlled by the subject so that threshold pain was maintained throughout the exposure. After the initial period of adjustment by the subject, radiation intensity was generally maintained constant although skin temperature for the pain threshold decreased from 44.9 C to 43.8 C. By using an intensity as low as 22 mcal/cm2/sec, threshold pain was evoked in 29 min at a skin temperature of 42.2 C. In both groups, once pain had been established it did not disappear. It is inferred from these observations that thermal pain does not adapt for near-threshold stimulation in the period between onset of pain at 30 sec and termination of stimulation.

Purpose and Hypothesis: Trigger points (TrP) is one of the most common causes of musculoskeletal disorders. Myofascial trigger point in vastus lateralis muscle has been reported high prevalently in subjects with patellofemoral pain syndrome. The purpose of this study was to investigate the effects of dry needling and kinesio tape on trigger point in vastus lateralis muscle. Randomized controlled trial designed to investigate the effect of Dry Needling (DN) and Kinesio Taping (KT) on pain intensity and knee disability after session’s treatment in individuals with trigger point (TrP) in Vastus Lateralis (VL) muscle. Methods: 30 subjects with TrP in the VL muscle participated in this study. Subjects were randomly assigned to a DN group ([Formula: see text]) or KT group ([Formula: see text]). Results: Statistical analysis (paired [Formula: see text]-test) revealed a significant improvement in VAS during activity and KOOS scores after three sessions treatment in both of groups compared with before treatment ([Formula: see text]). But PPT was not increased after one week treatment. VAS using an algometer was decreased only at DN group ([Formula: see text]). The results showed no significant changes in variables immediately after intervention. The ANCOVA revealed no significant differences between the DN and KT groups on the post-measurement VAS during activity, VAS using an algometer, PPT, KOOS scores ([Formula: see text]). Conclusion: DN and KT produce an improvement in pain intensity and knee disability and may be prescribed for PFPS subjects with TrP in VL muscle especially when pain relief is the goal of the treatment.

Abstract Background Human hairy (not glabrous skin) is equipped with a subgroup of C-fibers, the C-tactile (CT) fibers. Those do not mediate pain but affective aspects of touch. CT-fiber-activation reduces experimental pain if they are intact. In this pilot study we investigated pain modulating capacities of CT-afferents in CRPS. Methods 10 CRPS-patients (mean age 33 years, SEM 3.3) and 11 healthy controls (mean age 43.2 years, SEM 3.9) participated. CT-targeted-touch (brush stroking, velocity: 3 cm/s) was applied on hairy and glabrous skin on the affected and contralateral limb. Patients rated pleasantness of CT-targeted-touch (anchors: 1 “not pleasant”—4 “very pleasant”) twice daily on 10 days. Pain intensity (NRS: 0 “no pain” – 10 “worst pain imaginable”) was assessed before, 0, 30, 60 and 120 min after each CT-stimulation. To assess sensory changes, quantitative-sensory-testing was performed at the beginning and the end of the trial period. Results CT-targeted-touch was felt more pleasant on the healthy compared to the affected limb on hairy (p < 0.001) and glabrous skin (p 0.002), independent of allodynia. In contrast to healthy controls patients felt no difference between stimulating glabrous and hairy skin on the affected limb. Thermal pain thresholds increased after CT-stimulation on the affected limb (cold-pain-threshold: p 0.016; heat-pain-threshold: p 0.033). Conclusions CT-stimulation normalizes thermal pain thresholds but has no effect on the overall pain in CRPS. Therefore, pain modulating properties of CT-fibers might be too weak to alter chronic pain in CRPS. Moreover, CT-fibers appear to lose their ability to mediate pleasant aspects of touch in CRPS.

Objective: To determine the changes produced by trigger point dry needling (TrP-DN) of sternocleidomastoid in patients with neck pain, and to observe how it might modify cervical motor control (CMC). Design: Single-centre, randomised, double-blinded clinical trial. Setting: Participants were recruited through advertising. The duration of the study was 6 months. Subjects: Thirty-four subjects with non-specific neck pain, aged over 18 years with an active myofascial trigger point in sternocleidomastoid, participated in the study. They were randomly assigned to treatment or control groups. Methods: TrP-DN inside or (1.5 cm) outside of the active myofascial trigger point of sternocleidomastoid. Main outcome measures: CMC, visual analogue scale and cervical range of motion were assessed before treatment, immediately post treatment, and 24 h, 1 week and 1 month after the intervention; the neck disability index was evaluated before treatment and 1 month later. Results: With a confidence interval of 99%, TrP-DN of sternocleidomastoid was associated with a decrease in pain after 1 week and CMC improved 1 month after the intervention (p < 0.001), when compared with baseline measurements, within the experimental group; there were no statistically significant differences between experimental and control groups. Conclusion: The effects of TrP-DN inside and outside of active myofascial trigger points did not differ in this study. Both interventions were associated with a similar temporal effect, specifically a reduction in neck pain at 1 week and an increase CMC at 1 month. However, these findings should be interpreted with caution due to the lack of a contemporaneous untreated control group.
