PURPOSE: This study examined the effect of muscle thickness of the deep cervical flexor muscle, muscle tonicity, and muscle fatigue of the superficial cervical flexor muscle by applying a functional latex pillow to patients with chronic cervical pain. METHODS: An experimental group using a functional latex pillow and a control group using a general pillow were assigned randomly to 30 people. Each pillow was applied in a comfortable lying position in the experimental group and control group. The deep cervical flexor muscle thickness was measured in the longus colli and longus capitus using ultrasonography. The muscle tonicity and muscle fatigue of the superficial cervical flexor muscle were measured separately in the sternocleidomastoid muscle using a myotonometer and electromyography. RESULTS: In the experimental group(functional latex pillow), the muscle tonicity of the superficial cervical flexor muscle like the sternocleidomastoid muscle was significantly lower than that of the control group (general pillow)(p < .01). CONCLUSION: This study suggests that the functional latex pillow may effectively reduce the muscle tonicity of the sternocleidomastoid muscle, which is the superficial cervical muscle, in patients with chronic cervical pain. On the other hand, it was not effective on the muscle thickness of the deep cervical flexor muscle and muscle fatigue of the superficial cervical flexor muscles.

A 2-year-old male, 3 kg body weight Japanese Chin was injured in the automobile accident three months ago. The dog became antebrachiocarpal joint instability, and performed pancarpal arthrodesis using 3 K-wires in localanimal hospital. But, the result was failure. Therefore the dog was referred to Chonbuk Animal Medical Center, Chonbuk National University. In physical examination, right carpal joint instability, knuckling sign and pain were evident. In radiography, sclerosis was observed on the 4th carpal bone. Complete blood count (CBC), serum chemistry and urinalysis finding were within reference ranges. Pancarpal arthrodesis was re-performed using 7-hole plate. However, mild skin and muscle defects was appeared by skin tension of extremity. We expected that granulation would fill the defect, but inflammation was continued on the lesions for 3 days. So, operation which is filling it was done by using the muscle flap and tubed skin flap. The donor muscles were flexor carpi radialis and superficial digital flexor muscles. After 7 days, the muscle flap was survived, but tubed skin flap was necrosed. After 20 days, the skin defect was substituted with granulation tissues. The flexor carpi radialis muscle and superficial digital flexor muscle transposition can be a useful procedure for reconstructing soft tissue defects in the carpal and metacarpal areas.

Purpose: The purpose of this study was to investigate the effect of open and closed kinetic chain exercises with a sling on neck flexor thickness during chin-in movement in office workers with forward head posture. Methods: Thirty-one selected subjects randomly performed chin-in movement in open kinetic chain and closed kinetic chain exercises using a sling. All subjects were measured for their neck flexor thickness using ultrasound measurement equipment during the performance of chin-in movement in open and closed kinetic chain exercised. A paired t-test was used to compare the thickness of the total neck flexor, superficial, and deep neck flexor, respectively, between open and closed kinetic chain exercises with chin-in movement. Results: The thickness of the superficial neck flexor diminished in size more greatly during the chin-in movement with the closed kinetic chain than the open kinetic chain, but this was not a statistically significant difference (p > 0.05). On the other hand, the thickness of the total neck flexor and deep neck flexor had more greatly increased during the chin-in movement with the closed kinetic chain than the open kinetic chain, and this was a statistically significant differences (p < 0.05). Conclusion: This study suggested that chin-in movement with a closed kinetic chain is more effective in activating the deep neck flexor than the open kinetic chain. Thus, we believe that the closed kinetic chain exercise using a sling is an effective intervention to correct the postural alignment of individuals with forward head posture.

Purpose: This paper proposes proper and effective neck exercises by comparing the deep and superficial cervical flexor muscle activities and thickness according to the pressure level during cranio-cervical flexion exercises between a normal posture group and forward head posture group. Methods: A total of 20 subjects (8 males and 12 females) without neck pain and disabilities were selected. The subjects' craniovertebral angles were measured; they were divided into a normal posture and a forward head posture group. During cranio-cervical flexion exercises, the thickness of the deep cervical flexor neck muscle and the activity of the surface neck muscles were measured using ultrasound and EMG. Results: The results showed that the thickening of the deep cervical flexor was increased significantly to 28 and 30 mmHg in the forward head posture group. The sternocleidomastoid muscle activity increased significantly to 24, 26, 28, and 30 mmHg in the forward head posture group. The anterior scalene muscle activity increased significantly to 26, 28, and 30mmHg in the forward head posture group. A significant difference of 26, 28, and 30 mmHg in the sternocleidomastoid and anterior scalene muscles was observed between two groups. Conclusion: To prevent a forward head posture and maintain proper cervical curve alignment, the use of the superficial cervical flexor muscles must be minimized. In addition, to perform a cranio-cervical flexion exercises to effectively activate the deep cervical flexor muscles, 28 and 30 mmHg for normal posture adults and 28 mmHg for adults with forward head postures are recommended.

The muscles of the sole have been traditionally categorized into four layers, but it is more practical to divide them into peripheral and central groups. The peripheral groups include medial and lateral groups. The central plantar muscles are more numerous and divided into superficial and deep layers. During routine dissection in the Department of Anatomy, All India Institute of Medical Sciences Bibinagar, Hyderabad, variations are been observed in the plantar intrinsic muscle in the left foot & right foot of a 53-year-old male cadaver. This is the first cadaveric report of a combination of discrepancies especially the inter-tendinous connection between quadratus plantae and flexor digitorum brevis. Similar observations in the literature were not found by us. It is important to identify and study these dissimilarities of muscles of the sole for surgeons, anatomists, radiologists and orthopaedics as these muscles and tendons are used in foot reconstructive procedures, and for the treatment of some congenital anomalies.

This study compared the effects of the initial head position (i.e., a HHP versus a relaxed head position) of subjects with and without a FHP on the thickness of the deep and superficial neck flexor muscles during CCF. The study recruited 6 subjects with a FHP and 10 subjects without a FHP. The subjects performed CCF in two different head positions: a HHP, with the head aligned so that the forehead and chin formed a horizontal line, and a relaxed head position (RHP), with the head aligned in a self-selected comfortable position. During the CCF exercise, the thickness of the longus colli (LCo) and the thickness of the sternocleidomastoid (SCM) were recorded using ultrasonography. The thickness of each muscle was measured by Image J software. The statistical analysis was performed with a two-way mixed-model analysis of variance. The thickness of the SCM differed significantly (p<.05) between the subjects with and without FHP. According to a post $h^{\circ}C$ independent t-test, the change in thickness of the SCM increased significantly during CCF in the subjects with FHP while adopting a HHP compared to that in the subjects without FHP. The change in thickness of the SCM was not significantly different between the two positions in subjects without FHP, and there was no significant change in thickness of the LCo muscle during the CCF exercise according to the initial position in both subjects with and without FHP. The results suggest that CCF should be performed in RHP to minimize contraction of the SCM in subjects with a FHP.

Purpose: Many causes for triggering or locking of the fingers have been discussed in other literatures. The most common one is known stenosing tenosynovitis, which causes, a mismatch between the volume of the flexor tendon sheath and its contents. However, repeated trauma to the hand is uncommon cause of trigger finger. Therefore, we present a case of a rare condition of stenosing tenosynovitis which developed from a repeated relatively weak superficial flexor tendon injury. Methods: The patient was a 62-year-old woman who showed a painless, fixed and round mass on her right hand with no particular cause. Active and passive range of motion of the metacarpophalangeal joint of long finger was limited in flexion and extension. Ultrasonographic finding showed injured flexor digitorum superficialis tendon had fibrillar architecture with swelling between hyperechoic synovial membrane and hypoechoic surrounding area. Surgical exploration revealed that a bunched portion of the flexor digitorum superficialis and A1 pulley cause triggering during operation after adhesiolysis of scar tissue. Results: After releasing the A1 pulley, the range of motion of the metacarpophalangeal joint of long finger showed no limitation and histological examination of the subcutaneous tissue revealed fibrous fatty degeneration. In this case, releasing the A1 pulley with adhesiolysis of the subcutaneous scar tissue was successful and we obtained good functional outcome. Conclusion: We examined a patient in whom a repetitive impact forces to the palm caused longitudinal tear of the flexor tendon, leading to trigger finger. We experienced a rare case of stenosing tenosynovitis and trigger finger caused after close injury to flexor digitorum superficialis and its degenerative changes that caused mass like effect. To the best of authors' knowledge, our case of close injury to the flexor digitorum superficialis and unique morphologic change before rupture of tendon is rarely to be reported.

This report describes a variation of the tendinous slip of the flexor digitorum longus (FDL) for the great toe. In addition, compositions of the long flexor tendons for all five toes were examined. The tendons of the FDL in the foot were investigated in 66 specimens of embalmed Korean adult cadavers. The tendons of the flexor hallucis longus (FHL) and the FDL with the lumbrical muscles were cut at the calcaneus and the metatarsophalangeal joints and were removed en bloc specifically to observe the FDL and the FHL tendons of the great toe. The tendinous slip of the FDL for the great toe was found bilaterally in the foot of a 52-year-old male. Its prevalence was two of 66 specimens (3.0%). The tendinous slip of the FDL for the great toe passed forward the great toe, and it constituted the superficial portion of the long flexor tendon for the great toe. The tendon of the FHL passed forward to constitute the deep portion of the long flexor tendon for the great toe. Thus, both the tendinous slip of the FDL and the tendon of the FHL composed the long flexor tendon for the great toe. The tendinous slip of the FDL and the tendon of the FHL for the great toe were similar in thickness; thus, each tendinous slip of the FDL and the tendon of the FHL were approximately one-half of the long flexor tendon for the great toe in thickness. The present study demonstrated an anatomical variation of the interconnection between the FHL and the FDL tendons, which will be useful for various surgeries and biomechanical research.
