Robot arms for humanoid are widely developed for medical, welfare and education use. Surface electromyogram (sEMG) signals which are the electrical signals obtained from surface of human skin using electrodes have been mainly used for classification of hand motions. However, it is difficult to classify detailed motions such as finger motions and wrist pronation or supination. Moreover, Kinect is an integration sensor device which can capture human joints movement. It also has been widely used for recognition of body motions in many fields...

Studies of upper limb motion analysis using surface electromyogram (sEMG) signals measured from the forearm plays an important role in various applications, such as human interfaces for controlling robotic exoskeletons, prosthetic hands, and evaluation of body functions. Though the sEMG signals have a lot of information about the activities of the muscles, the signals do not have the activities of the deep layer muscles. We focused on forearm deformation, since hand motion brings the muscles, tendons, and skeletons under the skin...

INTRODUCTION: The management of highly comminuted distal radius fractures still remains a major treatment challenge. Articular comminution and compromised bone quality are the culprits. One novel approach is the technique of Internal Distraction Plating which involves "bridging" the fracture with the use of a standard 3.5mm plate applied dorsally in distraction from the radius, proximal to the fracture, to the long finger metacarpal distally, bypassing the comminuted segment. The plate is removed once fracture union has been achieved...

Lymphoma involvement of peripheral nerves is rare and it may mimic benign neurogenic tumors or neuropraxic injury. This study presents three patterns of presentations in four patients with neurolymphomatous involvement of their peripheral nerves. We reviewed the clinical records of four patients who underwent exploratory brachial plexus surgery (n = 1), pronator tunnel decompression (n = 1) and peripheral nerve exploration (n = 2) and subsequently found to have neurolymphomatosis (NL). Histological diagnoses were diffuse large B-cell lymphoma (n = 3) and NK/T-cell lymphoma (n = 1)...

We assessed the factors influencing the planning of actions required to manipulate one of two everyday objects with matching dimensions but openings at opposite ends: a cup and a vase. We found that, for cups, measures of movement preparation to reach and grasp the object were influenced by whether the grasp was made to the functional part of the object (wide opening) and whether the action would end in a supinated as opposed to a pronated grasp. These factors interacted such that effects of hand posture were found only when a less familiar grasp was made to the non-functional part of the cup (the base)...

Nerve entrapment syndromes occur because of anatomic constraints at specific locations in both upper and lower limbs. Anatomical locations prone to nerve entrapment syndromes include sites where a nerve courses through fibro-osseous or fibromuscular tunnels or penetrates a muscle. The median nerve (MN) can be entrapped by the ligament of Struthers; thickened biceps aponeurosis; between the superficial and deep heads of the pronator teres muscle and by a thickened proximal edge of flexor digitorum superficialis muscle...

BACKGROUND: Depending on the direction of the subtalar joint, a foot deformity generally tends towards pronation (pes planovalgus) or supination (pes cavovarus). However, the combination of hindfoot varus and flat midfoot/forefoot (pes planovarus) is an exception to this rule. Pes planovarus has so far only been referred to in connection with Müller-Weiss disease and congenital disease. We diagnosed pes planovarus in otherwise healthy patients without these diseases. METHODS: Forty patients with 54 symptomatic feet who were treated between August 2012 and July 2016 were included (mean age, 44...

BACKGROUND: Lateral epicondylitis is a common cause of pain and upper limb dysfunction. The use of counterforce straps for treatment of lateral epicondylitis is widespread. This kind of orthosis can be modified to have a greater effect on relieving pain by reducing tension on the origin of the extensor pronator muscles. OBJECTIVES: To determine the immediate effects of a newly designed orthosis on pain and grip strength in patients with lateral epicondylitis. MATERIALS AND METHODS: Twelve participants (six men and six women) were recruited (mean age = 41 ± 6...

INTRODUCTION: Malunion occurs in approximately 23% of non-operatively treated and 11% of operatively treated distal radius fractures. The decision whether to correct a malunion is primarily based on functional impairment and wrist pain. The purpose of this study was to assess the long-term functional outcomes of corrective osteotomies for symptomatic malunited distal radius fractures. METHODS: All consecutive corrective osteotomies of the distal radius performed in one centre between January 2009 and January 2016 were included...

This study used an OpenSim inverse-dynamics musculoskeletal model scaled to subject-specific anthropometrics to calculate three-dimensional intersegmental moments at the shoulder, elbow and wrist while 10 subjects used 1 and 2 lb hammers to drive nails. Motion data were collected via an optoelectronic system and the interaction of the hammer with nails was recorded with a force plate. The larger hammer caused substantial increases (50-150%) in moments, although increases differed by joint, anatomical component, and significance of the effect...

Using high-speed videography, we investigated how fruit flies compensate for unilateral wing damage, in which loss of area on one wing compromises both weight support and roll torque equilibrium. Our results show that flies control for unilateral damage by rolling their body towards the damaged wing and by adjusting the kinematics of both the intact and damaged wings. To compensate for the reduction in vertical lift force due to damage, flies elevate wingbeat frequency. Because this rise in frequency increases the flapping velocity of both wings, it has the undesired consequence of further increasing roll torque...

INTRODUCTION: Fractures of the head or neck of the radius account for 5% of elbow fractures in adults. Treatment varies between authors. MATERIAL AND METHODS: We report a retrospective series of 12 cases of percutaneous reduction of Mason II radial head fracture, without internal fixation. RESULTS: All fractures consolidated, without secondary displacement. There were no postoperative complications. Mean ranges of motion were 136° flexion-extension and 175° pronation-supination...

The ulnar collateral ligament (UCL) of the elbow acts as the primary restraint to valgus force experienced in the late cocking and early acceleration phases of overhead throwing. If the UCL or dynamic flexor-pronator musculature is incompetent, elbow extension and valgus torque, as seen in throwing, can result in posteromedial impingement with subsequent chondromalacia and osteophyte formation. Before the first UCL reconstruction, performed by Frank Jobe in 1974, this injury was considered career ending in overhead athletes...

Proper functioning of the hand relies on its capacity to rotate and point the palm upward (i.e. supination) or downward (i.e. pronation) when standing up with the elbow in 90° flexion. Hand rotation is possible because of forearm rotation and also rotation of the whole upper limb at the shoulder. Two distinct mechanisms contribute to hand rotation: one in which the ulna is immobile and another in which the ulna is mobile. In this review, we first summarize how evolution of the human species has led to the progressive development of specific forearm anatomy that allows for pronation and supination...

BACKGROUND: Progressive biceps loading is recommended in the nonoperative and operative rehabilitation of biceps-related disorders. Previous researchers have proposed a continuum of exercises with low to moderate biceps loads to be used in the early and intermediate phases of rehabilitation. A progression of exercises with moderate to high biceps loads to be used in the more advanced phases of rehabilitation is lacking. PURPOSE: To describe a progression of exercises with progressive moderate to high loads on the biceps brachii (BB) based on electromyographic (EMG) analysis...
