Diaphragmatic Mobility and Chest Expansion in Patients with Scapulocostal Syndrome: A Cross-Sectional Study.

Scapulocostal syndrome (SCS) is a subset of myofascial pain syndrome affecting the posterior shoulder and upper back area. Some of the affected muscles are attached to the rib cage, which may affect diaphragmatic mobility and chest expansion. The purpose of this study was to investigate the characteristics of diaphragmatic mobility and chest expansion in patients with SCS. Twenty-nine patients with SCS and twenty-nine healthy participants of a similar age, gender, weight, and height were included in the study. All participants were evaluated for diaphragmatic mobility (DM) by real-time ultrasound (RTUS) and for chest expansion (CE) using a cloth tape measure. An independent t-test was used to compare the outcome variables between groups. The DM value in the SCS group was 46.24 ± 7.26 mm, whereas in the healthy group it was 54.18 ± 9.74 mm. The DM value was lower in the SCS group compared to in healthy participants (p < 0.05). Chest expansion at the axilla, the fourth intercostal space (4th ICS), and the xiphoid level in the SCS group was 7.26 ± 1.13, 6.83 ± 0.94, and 6.86 ± 1.25, respectively, while chest expansion at the axilla, 4th ICS, and xiphoid level in the healthy group was 7.92 ± 1.39, 7.54 ± 1.43, and 8.13 ± 1.32, respectively. Chest expansion at the 4th ICS and the xiphoid level in the SCS group was significantly lower than in the healthy group (p < 0.05). Patients with SCS presented a decrease in diaphragmatic mobility and chest expansion. Therefore, SCS treatment programs ought to add breathing exercises to improve lung expansion.

A Randomized Controlled Trial of Warming and Unblocking Acupuncture Treatment for Scapulocostal Syndrome / 上海针灸杂志

Objective To investigate the clinical efficacy of warming and unblocking acupuncture in treating scapulocostal syndrome.Method Eighty patients with scapulocostal syndrome meeting the inclusion criteria were allocated by simple randomization to warming and unblocking acupuncture and conventional acupuncturegroups, 40 cases each.The warming and unblocking acupuncture group received warming and unblocking acupuncture at points Tianzong(SI11), Jianjing(GB21)and Dazhui(GV14)on the affected side and affected chest Huatuo jiaji(Ex-B2)points and uniform reinforcing-reducing acupuncture at points Quchi(LI11), Hegu(LI4)and Waiguan(TE5).The conventional acupuncture group received uniform reinforcing-reducing acupuncture at the same points as those in the warming and unblocking acupuncture group after arrival of qi.Both groupswere treated once every other day, 10 days as a course, for a total of one course.Pain severity was assessed using the Pain Visual Analogue Scale(VAS) in the two groups of patients before and after treatment.Theclinical therapeutic effects were evaluated by follow-up at one month after the completion of treatment.Result The total efficacy rate was 95.0% (38/40) in the warming andunblocking acupuncture group and 80.0% (32/40) in the conventional acupuncture group; there was a statistically significant difference (P<0.05).The PainVisual Analogue Scale(VAS) score was significantly lower in the two groups of patients after treatment than before treatment; there was a statistically significant difference (P<0.05).The VAS score was decreased more in the warming and unblocking acupuncture group after treatment and at the follow-up one month after the completion of treatment (P<0.05).Conclusion Warming and unblocking acupuncture has clinically a better therapeutic effect onscapulocostal syndrome.

Effects of scapular stabilization exercise on pain related parameters in patients with scapulocostal syndrome: A randomized controlled trial.

The aim of this study was to evaluate the effects of scapular stabilization exercise (SSE) on pain intensity, pressure pain threshold (PPT), muscle tension and anxiety in patients with scapulocostal syndrome (SCS). Thirty-six patients were randomly assigned to receive a 30-minute session of either SSE or control (relaxed by lying supine quietly) for 12 sessions over a period of 4 weeks. Pain intensity, PPT, muscle tension and anxiety were assessed before and after a 4-week intervention period and 2 weeks after the intervention period. The adverse effects were evaluated after completion of the intervention period. Results indicated that the SSE group showed a significant improvement in all parameters after the intervention period and at 2 weeks after the intervention period (p < 0.05). For all outcomes, similar changes were not found in the control group. The adjusted post-test mean values of each assessment time point for pain intensity, muscle tension and anxiety were significantly lower in the SSE group than those of the control group (p < 0.05). Moreover, the values for PPT were significantly higher in the SSE group (p > 0.05). There were no reports of adverse effects in either group. We therefore conclude that SSE can improve pain related parameters and could be an effective intervention for SCS.

A technical report on ultrasound-guided scapulocostal syndrome injection.

INTRODUCTION: We describe a case report and technique for using an ultrasound scanner and a linear transducer to guide serratus posterior superior (SPS) muscle injection. A 43-year-old female presented with chronic pain centered under the right upper portion of her scapula impacting her activities of daily living. METHODS AND MATERIALS: For the ultrasound-guided SPS muscle injection, the patient was placed in the prone position. The transducer was oriented in a transverse orientation at the level of the C6-T1 vertebrae. Here the SPS muscle attaches to the lower portion of the ligament nuchae and the intervening interspinous ligaments. The muscle fibers run inferiorly and laterally to attach to the 2nd-5th ribs which were identified along with the lateral portion of the serratus posterior superior muscle which is covered by the scapula. Real-time imaging was used to direct a spinal needle into the trigger points of the SPS muscle, where solution was injected under direct vision. The patient's pain symptoms improved significantly. CONCLUSION: Serratus posterior superior injection can confirm a diagnosis of scapulocostal syndrome and be therapeutically beneficial.
