An unusual origin of the common interosseous artery is reported in the paper. During educational dissection of a 37-year-old male, a rare variation in the origin of common interosseous artery of the right upper limb was observed. The common interosseous artery directly separated from radial artery. The right anterior interosseous artery is continued from common interosseous artery. Anterior and...

Introduction Flexor digitorum longus, flexor hallucis longus and tibialis posterior are the three deep muscles of the posterior compartment of the leg. Flexor digitorum longus arises from the posterior surface of tibia below the soleal line medial to tibialis posterior, and by a broad tendon from the fibula, then courses deep to the flexor retinaculum in the tarsal tunnel to enter the sole of f...

The practical operation of wearable robots requires intuitive, compact, yet reliable control interfaces. However, current myoelectric interfaces based on surface electromyography (EMG) often fail to achieve these requirements by demanding multiple sensors and exhibiting unreliable performance under limb posture changes. In this study, we show that a interface the musculotendinous junctions (MTJ...

Treatment options for dystonia are not curative but symptomatic; the treatment of choice for focal dystonias is repeated botulinum toxin injections. Here, we present the case of a 46-year-old beautician with focal dystonia in her left hand that affected her ability to work. Pharmacological treatment with clonazepam and gabapentin failed to resolve her symptoms and was discontinued due to side e...

PURPOSE After complex hand trauma, restoration of tendon strength is challenging. Tendon insertion tears typically heal as fibrous scars after surgical reconstruction and create a weak point at the tendon-bone interface. In addition, major tendon loss may overwhelm the amount of available autograft for reconstruction. An off-the-shelf product may help address these challenges. We hypothesized t...

We investigated beta-band intermuscular coherence (IMC) in 92 healthy adults stratified by decade of age, and analysed variability between and within subjects. In the dominant upper limb, IMC was estimated between extensor digitorum communis and first dorsal interosseous as well as between flexor digitorum superficialis and first dorsal interosseous. In the ipsilateral lower limb, IMC was measu...

A 77-year-old Japanese woman developed gait disturbance during her 50s. The gait disturbance and a muscle weakness in her lower limbs gradually worsened, and she consulted our hospital at the age of 76. Neurological examination showed proximaldominant muscle weakness and atrophy, particularly in the quadriceps muscles. In her left hand, the muscle strength during finger flexion at the distal in...
