Trunk muscle weakness and imbalance are risk factors for postural instability, low back pain, and poor postoperative outcomes. The association between trunk muscle strength and aging is poorly understood, and establishing normal reference values is difficult. We aimed to establish the validity of a novel portable trunk muscle torque measurement instrument (PTMI). We then estimated reference data for healthy young adults and elucidated age-related weakness in trunk muscle strength. Twenty-four university students were enrolled to validate values for PTMI, and 816 volunteers from the general population who were recruited to the Iwaki Health Promotion Project were included to estimate reference data for trunk muscle strength...

Lotte Meteyard, Nicholas Holmes
BACKGROUND: The magnetic pulse generated during transcranial magnetic stimulation (TMS) also stimulates cutaneous nerves and muscle fibres, with the most commonly reported side effect being muscle twitches and sometimes painful sensations. These sensations affect behaviour during experimental tasks, presenting a potential confound for 'online' TMS studies. NEW METHOD: Our objective was to systematically map the degree of disturbance (ratings of annoyance, pain, and muscle twitches) caused by TMS at 43 locations across the scalp...

Chronic inflammation is pathologically associated with various clinical conditions such as rheumatoid arthritis. Several anti-inflammatory and analgesic drugs currently available in market presents a wide range of problems. Therefore, the current study was aimed to evaluate anti-inflammatory and analgesic activities of newly synthesized compound 2-(5-mercapto-1,3,4-oxadiazol-2-yl)-N-propylbenzenesulphonamide (MOPBS). Carrageenan and CFA-induced models were developed for evaluation of anti-inflammatory and analgesic activity...

Patients with complex regional pain syndrome (CRPS) exhibit diverse symptoms, such as neuropathic pain, allodynia, local edema and skin color changes in the affected lesion. Although nerve injury may cause CRPS, pathophysiological mechanisms underlying the syndrome are unclear, and local edema, a characteristic of CRPS, has not been evaluated quantitatively for technical reasons. Here, using a rat spinal nerve ligation-induced CRPS model, we show that edematous changes in gastrocnemius muscle can be detected quantitatively by diffusion magnetic resonance imaging (MRI)...

We evaluated, by means of a non-invasive procedure based on Magnetic Resonance Imaging, the masticatory muscular microstructure in a 55 year-old-female patient affected by bruxism. The patient underwent MR examination before and after one month of splint therapy, when she referred the complete disappearance of all symptoms. By means of Diffusion Tensor Imaging we observed changes at microstructural level of masticatory muscular complex. We conclude that DTI may be a useful instrument both to perform panoramic reconstruction of the masticatory muscle complex and to investigate microstructural modifications related to the pain relief in bruxism...

BACKGROUND: Subacromial pain pumps are used for analgesia after arthroscopic rotator cuff surgery. However, there is controversy about myotoxic or tendinotoxic effects of local anesthetics. HYPOTHESIS: Ropivacaine administered via a subacromial pain pump would have no adverse effect on rotator cuff tendon healing, fatty degeneration, strength, or functional outcomes after arthroscopic repair. STUDY DESIGN: Cohort study; Level of evidence, 3...

Lymphangiomatosis is an uncommon disease process characterized by multisystem lymphatic malformations that can involve numerous body systems, including organs, muscles, soft tissues, and bones. Involvement of the nervous system is rare and has even been previously described as a site of sparing. We present a case of a 24-year-old female with known lymphangiomatosis, presenting with acute onset of lower extremity paresthesias, weakness, and new urinary retention. MRI of the pelvis revealed lymphangiomatosis of the sacral plexus, which has not been previously reported...

A 15-year-old Selle Francais gelding was presented to the equine referral hospital for treatment of a left guttural pouch mycosis previously diagnosed. After induction, the horse was shortly hoisted by all four feet, moved on a padded surgical table, and positioned in right lateral recumbency. In order to reduce the risk of bleeding during surgical manipulation of the carotid and maxillary arteries, a mean arterial pressure between 60 and 70 mmHg was targeted. After surgery, the horse was moved in a padded recovery box keeping the same lateral recumbency...

Chronic injury of limb nerves leading to neuropathic pain affects deep somatic nerves. Here the functional properties of injured afferent fibers in the lateral gastrocnemius-soleus nerve were investigated 20 days and 80 days after suturing the central stump of this muscle nerve to the distal stump of the sural nerve in anesthetized rats. Neurophysiological recordings were made from afferent axons identified in either the sciatic nerve (87 A-, 63 C-fibers) or the dorsal root L4/L5 (52 A-, 26 C-fibers) by electrical stimulation of the injured nerve...

Bifid condyle is a rare entity with a difficult diagnosis and usually identified as an incidental finding on routine radiographic examination. The etiology is not well known, possible causes may be developmental, traumatic, vascular, abnormal muscle pulling, nutritional, endocrinal, teratogenic, and infections. The orientation of the condylar heads can behelpful for the etiological diagnosis.This case report describes a 56-year-old woman who suffered from a unilateral, progressively increasing, radiating pain which intensified with the movement of the mandible and includes information about the diagnosis, management, radiographic and three-dimensional model features and review of the literature...

Eosinophilic fasciitis (EF), a rare rheumatic disease, usually affects the limbs symmetrically and generally spares the hands and feet. Cases of unilateral hand involvement are rarely reported. Here, we report such a rare case. Ultrasonography demonstrated thickening of the overlying skin and subcutaneous tissue, peripheral deep fascia, myositis of lumbrical muscles and adductor pollicis muscle, and edema surrounding flexor digitorum tendons. It reminds us that EF should be considered in the differential diagnosis of unilateral painful hand swelling despite being uncommon...

BACKGROUND: Abdominoplasty is the most frequently performed surgical procedure for body contour; in our experience, we have observed some patients with prominent bulging that is difficult to treat and that presents results that are unsatisfactory or have recurrences to conventional treatments. This leads us to carry out an analysis of the elements responsible for the containment and abdominal format. We determined that it may be due to an inability of an important sagging aponeurotic muscle of primary origin to support the abdomen and could be caused by predisposing factors...

The features of clinical symptoms, neurotic disorders and the level of subjective control were studied in patients with fibromyalgia. The analysis of relationship between the level of subjective control and neurotic symptoms (asthenia, depression, anxiety, hypochondria) depending the severity of main clinical manifestations of the disease was carried out. It was found that high intensity of fatigue, muscle pain, stiffness, insomnia, and an increase in the number of diagnostic tender points contribute to the formation of inverse correlation between the level of subjective control and neurotic disturbances...
