Numerical analysis of the change in skin color due to ecchymosis and petechiae generated by cupping: a pilot study

Effect of myofascial cupping vs integrated neuromuscular inhibition techniques on pain and neck movement in individuals with latent trigger point in trapezius

Background

Pain is the most common symptom for seeking therapeutic alternative to conventional medicine. Trigger points (TrP) being the most debilitating cause of nonspecific neck pain, are found to be more prevalent in trapezius muscle. Various instrument-based and other manual therapy techniques are effective in the treatment of TrP.

Objective

To compare the effect of Myofascial Cupping (MFC) and Integrated Neuromuscular Inhibition Technique (INIT) on the upper trapezius latent TrP on pain intensity, pressure pain threshold (PPT) & cervical range.

Method

A randomized trial controlled on 40 individuals aged 20-40 years, both gender with latent TrPs in upper trapezius excluding ones who have taken treatment for upper trapezius TrPs within 6 months. Participants were randomly allocated into 2 groups by chit method, one group received MFC and other INIT. Pre- and post-intervention assessment was done using NPRS, pressure algometer and goniometer.

Result

Within group, pain has significantly reduced after MFC and INIT with mean difference of 6 . 05 ± 0 . 8 and 4 . 95 ± 0 . 7 , respectively (p < 0 . 001 ). PPT increased in both groups (p < 0 . 001 ) with mean difference of 0 . 63 ± 0 . 3 and 0 . 28 ± 0 . 11 , respectively. Comparison between the groups showed significant difference in pain intensity (p = 0 . 003 ) suggesting MFC was more effective in reducing pain. However, a PPT (p=0.606) and neck lateral flexion to the contralateral side of TrP (p = 0 . 74 ) were not significant.

Conclusion

MFC was more effective than INITs in improving pain, however both interventions showed similar effect on PPT and neck lateral flexion on latent TrP in trapezius.

Quantitative Analysis of Tranexamic Acid Effects on Ecchymosis in Rhinoplasty

Background: Many methods have been described to reduce postoperative ecchymosis in rhinoplasty with tranexamic acid (TXA) remaining controversial. TXA remains a consideration for surgeons, however, may have serious side effects, including seizures, blood clots, and vision changes. Methods: A prospective study of primary rhinoplasty patients was performed from March 2019 to June 2019. TXA was used in 50 patients and postoperative ecchymosis was compared with 50 control patients. Adobe Photoshop was used to quantitate postoperative ecchymosis using multiple objective color scales. Results: One hundred subjects were enrolled in the study. Eighty-four females and 16 males were included. Photographs were taken on postoperative day 7. There were no significant differences among any of the Red, Green, Blue (RGB) and L*a*b* color subgroups with p > 0.05. There were no adverse events with TXA. Conclusions: In this study, TXA did not reduce postoperative ecchymosis in rhinoplasty when used both through intravenous and intraoperative injections.

Attentional Bias Toward Cupping Therapy Marks: An Eye-Tracking Study

Objective

Despite the many medical benefits, cupping therapy can be difficult for some patients due to unpleasant marks on the skin. As patients are afraid of the potential painful sensation from cupping therapy, the skin reactions might produce vigilance for treatment as pain-related information. We investigated whether individuals show negative emotions and attentional bias toward pain-related residual marks from cupping therapy on the body using an eye-tracking method.

Methods

Fifty pain-free volunteers were presented with four different kinds of visual stimulation, such as the back or face region and with or without cupping marks on the skin. A cupping and a control image were presented on one screen with one image on the left side of the screen and the other on the right (locations of the images were counterbalanced across participants). The eye movements of the participants were measured while they viewed the pictures. They completed the Empathy Quotient questionnaire before the experiment and evaluated the unpleasantness level to each image during the task.

Results

Images of the back and face with cupping marks were rated significantly more unpleasant and showed a significant attentional bias (significantly longer percentage fixation time) than the control images (attentional bias score: Back + cupping: 48.1 ± 2.8%; Back: -0.7 ± 3.4%; Face + cupping: 34.5 ± 2.5%; Face: -2.2 ± 2.9%). Individuals with greater empathy exhibited significantly higher unpleasantness (r = 0.323, p < 0.05) and less attentional bias (r = -0.279, p < 0.05) to the images with cupping marks.

Conclusion

The skin reactions caused by cupping therapy evoked negative emotional responses as well as attentional bias to the reaction sites. Our findings suggest that the emotional and attentional responses to cupping therapy might reflect potential reluctance to this therapy.

Cognitive and Emotional Aspects of Cupping Therapy

Cupping therapy has recently gained public attention and is widely used in many regions. Some patients are resistant to being treated with cupping therapy, as visually unpleasant marks on the skin may elicit negative reactions. This study aimed to identify the cognitive and emotional components of cupping therapy. Twenty-five healthy volunteers were presented with emotionally evocative visual stimuli representing fear, disgust, happiness, neutral emotion, and cupping, along with control images. Participants evaluated the valence and arousal level of each stimulus. Before the experiment, they completed the Fear of Pain Questionnaire-III. In two-dimensional affective space, emotional arousal increases as hedonic valence ratings become increasingly pleasant or unpleasant. Cupping therapy images were more unpleasant and more arousing than the control images. Cluster analysis showed that the response to cupping therapy images had emotional characteristics similar to those for fear images. Individuals with a greater fear of pain rated cupping therapy images as more unpleasant and more arousing. Psychophysical analysis showed that individuals experienced unpleasant and aroused emotional states in response to the cupping therapy images. Our findings suggest that cupping therapy might be associated with unpleasant-defensive motivation and motivational activation. Determining the emotional components of cupping therapy would help clinicians and researchers to understand the intrinsic effects of cupping therapy.

The Effectiveness of Cupping Therapy on Relieving Chronic Neck and Shoulder Pain: A Randomized Controlled Trial

The research aimed to investigate the effectiveness of cupping therapy (CT) in changes on skin surface temperature (SST) for relieving chronic neck and shoulder pain (NSP) among community residents. A single-blind experimental design constituted of sixty subjects with self-perceived NSP. The subjects were randomly allocated to two groups. The cupping group received CT at SI 15, GB 21, and LI 15 acupuncture points, and the control group received no intervention. Pain was assessed using the SST, visual analog scale (VAS), and blood pressure (BP). The main results were SST of GB 21 acupuncture point raised from 30.6°C to 32.7°C and from 30.7°C to 30.6°C in the control group. Neck pain intensity (NPI) severity scores were reduced from 9.7 to 3.6 in the cupping group and from 9.7 to 9.5 in the control group. The SST and NPI differences between the groups were statistically significant (P < 0.001). One treatment of CT is shown to increase SST. In conjunction with the physiological effect the subjective experience of NSP is reduced in intensity. Further studies are required to improve the understanding and potential long-term effects of CT.
