Agenesis or congenital hypoplasia of skeletal muscles occurs infrequently but may occur with specific conditions such as Poland syndrome. The trapezius muscle can vary in the extent of its bony attachments or may have additional slips, however congenital absence or hypoplasia is extremely rare. There are only a few reports of partial or complete absence of the trapezius muscle. Two cases of bilateral absence of the trapezius were both in males and were accompanied by the absence of additional muscle in the pectoral girdle. Herein, we describe a case of a 56-year-old male cadaver with bilateral hypoplasia of the trapezius. The muscle was largely represented by atrophied muscle fibers with an abundance of fibrotic or fatty connective tissue. This subject had very minor hypoplasia of the left pectoralis major muscle, but the remaining muscles of the pectoral girdle were normal. The spinal accessory nerve terminated in the sternocleidomastoid muscle on both sides, failing to reach the trapezius. We interpret these findings to be consistent with a minor variant of Poland syndrome.

Objective: The purpose of this study was to examine the effect on vital capacity (VC) and inspiratory muscle activation according to the anterior and posterior pelvic tilt positions. Design: One group pretest-posttest design. Methods: Twenty-six healthy adult men and women, age 19 to 27 years, volunteered to participate in this study. Forced vital capacity (FVC), and forced expiratory volume in 1 second ($FEV_1$) were measured by desktop spirometer in the pelvic positions during respiration, and muscle activation was recorded from sternocleidomastoid, upper trapezius, external intercostal, rectus abdominis, and external oblique muscles by surface electromyography (EMG) at the same time. EMG values were normalized by maximum muscle contractions (% maximum voluntary isometric contraction). Subjects were to breathe in as much air as possible and then exhale as quickly as possible in both anterior and posterior pelvic tilt positions. To measure lung capacity, inspiration was measured for 5 seconds and expiration was measured for 7 seconds with data collection taken place during the middle three seconds. Lung capacities were measured in each position three times. Results: For the results of this study, there was a significant increase in both FVC and $FEV_1$ values during the anterior pelvic tilting compared to the posterior pelvic tilting posture (p<0.05). The sternocleidomastoid, upper trapezius muscle, rectus abdominus and external oblique muscle activation was significantly increased during anterior pelvic tilt compared to the posterior pelvic tilt position (p<0.05). Conclusions: These findings suggest that pelvic anterior tilt position could be more effective for vital capacity and respiratory muscles activation during respiration.

Two hundred sisty five patients who complained of neck pain with stiffness and pain of the suprascapular area were studied. In most cases the anatomical locations of pain were in the levator scapulae muscles or trapezius muscles. Hyperactivity of dorsal scapular nerve or spinal accessory nerve which innervate those muscles was thought to be responsible for these pains. The hyperactivity of the nerves may be due to the spasm of the sternocleidomastoid muscle and the scalenus medius muscle which the nerves meet during their courses to the levator scapulae or trapezius muscles. Therefore, spasmolytic treatment on the scalenus medius provided effective relief for neck or shoulder pain.

The purpose of this study was to compare the muscle onset time of sternocleidomastoid (SCM) and rectus abdominalis (RA) muscle activity during head lift in supine position between cerebral palsy and healthy children. Ten cerebral palsy children and 10 age, sex-matched healthy children were recruited for this study. Muscle activity of the SCM and RA were collected by surface electromyography (MP100SWS). Results demonstrated that the muscle onset time order was not significantly different between cerebral palsy children and healthy children. However, the DMHT and ST between SCM and RA during head lift in supine position were significantly shorter in healthy children than in cerebral palsy children. Further studies are needed to clarify the mechanism of differences in muscle activation patterns during head lift in supine position in cerebral palsy children compared with healthy children.

We have conclusions after the study of muscular system about large intestine channel of hand yangmyung muscle. 1. Judging from many studies of interrelation between Meridian muscle and muscle. it is considered that Meridian muscle theory has some similarities with modern anatomical muscular system. 2. There is a wide defference betwean myofacial pain syndrome and meridian muscle theory in that the former explains each muscle individually, while the latter classifies muscles systematically in the view of organism. 3. It is considered that large intestine channel of hand yangmyung muscle contains extensor digitorum muscle, extensor muscle of index finger, brachioradialis muscle, triceps brachii muscle, Rhomboid major muscle, trapezius muscle, sternocleidomastoid muscle and muscle levator labii. 4. The symptoms of large intestine channel of hand yangmyung muscle is similar to referred pain of modern Myofacial pain syndrome, and the medical treatment of "I-Tong-Wi-Su" is similar to that of Myofacial pain syndrome.

Objective: To determine whether ultrasonography at initial presentation can help assess the clinical severity of congenital muscular torticollis (CMT) in infants without a sternocleidomastoid muscle (SCM) mass. Materials and Methods: This retrospective study included 71 infants aged less than 12 months (4.1 ± 2.3 months) with non-mass CMT. The clinical severity was divided into three grades (groups 1-3) based on the degree of lateral head bending or cervical rotation. The difference (SCM-D) and ratio (SCM-R) between the maximal thickness of the affected and non-affected SCMs were obtained using transverse and longitudinal ultrasonography. The sonographic echotexture and echogenicity of the involved SCM were reviewed. Results: A significant difference was observed in the SCM-D (0.42 ± 0.30 mm in group 1; 0.74 ± 0.50 mm in group 2; 1.14 ± 0.85 mm in group 3; p = 0.002) and SCM-R (1.069 ± 0.067 in group 1; 1.129 ± 0.087 in group 2; 1.204 ± 0.150 in group 3; p = 0.001) among the groups when measured along the longitudinal but not along the transverse ultrasonography plane. The areas under the curves of the SCM-R and SCM-D measured by longitudinal ultrasonography were 0.731 (p < 0.001) and 0.731 (p < 0.001) for group 1 versus groups 2-3. The proportions of heterogeneous echotexture or hyperechogenicity in the involved SCM did not differ significantly among the three clinical groups (all p > 0.05). Conclusion: Ultrasonography can aid in assessing the clinical severity of CMT in infants without an SCM mass at the time of initial diagnosis. The SCM-R and SCM-D helped grade the clinical severity when obtained by longitudinal scan.

We report here on a case of right side spasmodic torticollis (ST) that was refractory to botulinum toxin type A injection and medication. The patient finally underwent a selective ramisectomy with ipsilateral sternocleidomastoid muscle (SCM) resection, but the remaining symptoms slowly aggravated, and a contralateral left side SCM spasm began. As conservative therapy for reducing the spasmodic symptoms, accessory nerve block, upper cervical plexus block and stellate ganglion block were performed twice in a week. After 6 months, the spasmodic symptoms significantly decreased. The Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) decreased by more than 70%. After one year of serial intermittent local anesthetic blockade therapy, the patient became almost free from the original ST symptoms (TWSTRS = 1). Serial local anesthetic interventions for the ST patient may have a beneficial role on the pathological peripherocentral neural activity of the ST patient and can modulate motor-sensory integration in the patient.

Purpose: Intramuscular stimulation (IMS) shows good results in the treatment of chronic pain patients who did not respond to other treatments such as oral analgesics, trigger point injection, nerve block and epidural steroid injection. But, IMS procedure especially, patients with diabetes mellitus (DM) has sometimes serious problem. So, we present a very rare case of intramuscular abscess in the sternocleiomastoid muscle after IMS with literature review. Methods: A 66 year old male visited our department 7 days after IMS in the neck. His premorbid conditions and risk factors of deep neck infection was DM and old age. Computed tomographic scans of the head and neck region were performed in this patient: signs of deep neck infection, were seen enhanced abscess in the sternocleidomastoid muscle, cellulitis overlying tissue of the neck, and air bubbles involved muscle. Necrotic wound was excised serially and we treated this with the Vacuum-assisted closure (VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, drainage of the abscess with the VAC system, and then primary closure. The postoperative course was uneventful. Results: We suggest that many of the infectious complications may be preventable by strict adherence to aseptic techniques and that some of the other complications may be minimized by refining the techniques with a clear understanding of the medical disorders of patients. And, the refined technique using the VAC system can provide a means of simple and effective management for the cervical intramuscular abscess, with better cosmetic and functional results.

In adult congenital muscular torticollis (CMT) patients, physical therapy is not as effective because the development of sternocleidomastoid muscle (SCM) muscle is complete. While surgical release can address CMT in adult patients, the risk of general anesthesia and visible postoperative scar is a concern, expecially in patients with mild symptoms. In this paper, we report our experience in treating such patients with minimal-incision myotomy under local anesthesia. A review was performed for all adult patients who had undergone the simple myotomy procedure. Surgical indication was reserved for patients with mild fibrotic band in the SCM muscle with minimal lengthdiscrepancybetween the muscles. All patients had recognizable head tiltand palpation of fibrotic band on affected side of the neck. Surgical details are described in the main body of text. Three female patients had undergone the procedure. Torticollis was resolve in all patients with complete restoration of ranage of motion. There were no postoperative complications, and patient satisfaction was high. We have reported three cases of mild CMT in adult female patients, who had undergone minimal-incision myotomy under local anesthesia. Outcomes were satisafactory with no morbidity to report. With careful patient selection, this method offers an alternate treatment option for adult CMT patients with mild symptoms.
