Conditioning Electrical Stimulation Accelerates Regeneration in Nerve Transfers.

Ann Neurol 2020 May 24. Epub 2020 May 24.

Department of Surgery, University of Alberta, Edmonton, Alberta, Canada.

Objective: Compared to the upper limb, lower limb distal nerve transfer (DNT) outcomes are poor, likely due to the longer length of regeneration required. DNT surgery to treat foot drop entails rerouting a tibial nerve branch to the denervated common fibular nerve stump to reinnervate the tibialis anterior muscle for ankle dorsiflexion. Conditioning electrical stimulation (CES) prior to nerve repair surgery accelerates nerve regeneration and promotes sensorimotor recovery. Read More

Iterative Adjustment of Stimulation Timing and Intensity During FES-Assisted Treadmill Walking for Patients After Stroke.

IEEE Trans Neural Syst Rehabil Eng 2020 Jun 7;28(6):1292-1298. Epub 2020 Apr 7.

Functional electric stimulation (FES) is a common intervention to correct foot drop for patients after stroke. Due to the disturbances from internal time-varying muscle characteristics under electrical stimulation and external environmental uncertainties, most of the existing FES system used pre-set stimulation parameters and cannot achieve good gait performances during FES-assisted walking. Therefore, an adaptive FES control system, which used the iterative learning control to adjust the stimulation intensity based on kinematic data and a linear model to modulate the stimulation timing based on walking speed during FES-assisted treadmill walking, was designed and tested on ten patients with foot drop after stroke.

Department of Biomedical Engineering, The Hong Kong Polytechnic University, Hong Kong, China.

Red is perceived as a "winning color", which may influence actual and perceived performances in sports, but little effort has been done to assess the added value on colored foot insoles in basketball movements. This study examined if colored foot insole would influence perceived comfort and lower extremity biomechanics during drop landing. Nineteen male basketball players performed drop landing trials with different insoles (red arch-support, white arch-support, and white-flat) and landing heights (0. Read More

SBOR: a minimalistic soft self-burrowing-out robot inspired by razor clams.

Bioinspir Biomim 2020 Apr 7. Epub 2020 Apr 7.

Arizona State University, Tempe, Arizona, UNITED STATES.

We observe that the Atlantic razor clam (Ensis directus) burrows out of sand rapidly by simply extending and contracting its muscular foot. This is notably different from its well-known downward burrowing strategy or the dual-anchor mechanism, where closing/opening of the shell and dilation of the foot are also involved. Inspired by this burrowing-out strategy, we design a simple self-burrowing-out robot (SBOR) consisting of a single segment of fiber-reinforced silicone tube actuator and an external control board.

Effects of a 4-Week Short-Foot Exercise Program on Gait Characteristics in Patients With Stage II Posterior Tibial Tendon Dysfunction.

J Sport Rehabil 2020 Mar 31:1-9. Epub 2020 Mar 31.

Context: Clinically, it has been suggested that increased activation of intrinsic foot muscles may alter the demand of extrinsic muscle activity surrounding the ankle joint in patients with stage II posterior tibial tendon dysfunction. However, there is limited empirical evidence supporting this notion.

Objective: The purpose of this study was to investigate the effects of a 4-week short-foot exercise (SFE) on biomechanical factors in patients with stage II posterior tibial tendon dysfunction. Read More

Resolution of Preoperative Peroneal Nerve Palsy After Total Knee Arthroplasty: A Case Report.

JBJS Case Connect 2020 Jan-Mar;10(1):e1900366

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Boston, Massachusetts.

Case: We present the case of a 71-year-old man with right knee osteoarthritis (OA) and a varus deformity who developed a progressive common peroneal nerve palsy that resolved after total knee arthroplasty (TKA). After decades of knee pain, the patient gradually developed a foot drop as well as numbness and paresthesias over the foot dorsum during the course of 1 month. The patient underwent TKA and within 6 weeks postoperatively had complete resolution of the peroneal nerve symptoms. Read More

Advances in neuroprosthetic management of foot drop: a review.

J Neuroeng Rehabil 2020 03 25;17(1):46. Epub 2020 Mar 25.

Neural Rehabilitation Group, Cajal Institute, Spanish National Research Council (CSIC), Av. Doctor Arce, 37, 28002, Madrid, Spain.

This paper reviews the technological advances and clinical results obtained in the neuroprosthetic management of foot drop. Functional electrical stimulation has been widely applied owing to its corrective abilities in patients suffering from a stroke, multiple sclerosis, or spinal cord injury among other pathologies. This review aims at identifying the progress made in this area over the last two decades, addressing two main questions: What is the status of neuroprosthetic technology in terms of architecture, sensorization, and control algorithms?.

Transfer of the peroneal component of the sciatic nerve in total brachial plexus lesion: An anatomical feasibility study.

Injury 2020 Mar 19. Epub 2020 Mar 19.

OU Traumatology-Reconstructive Microsurgery, Department of Orthopaedics and Traumatology, CTO Hospital, Torino, Italy.

Closed brachial plexus lesions (BPLs) are generally associated with a traumatic mechanism of forced traction between the neck and the shoulder-arm complex. For brachial plexus reconstruction different techniques have been proposed with donor motor nerves like intercostal nerves, or the ipsilateral cervical plexus, the phrenic nerve, the contralateral C7 root, and many others. Despite all these surgical possibilities, the overall recovery is generally poor and not satisfactory. Read More

Muscle hernias of the extremities most commonly occur in the leg, between the knee and ankle. Symptomatic muscle hernias in the leg are rare cause of chronic leg pain and neuropathy, and not routinely encountered in surgical practice. Although this condition is especially an esthetic problem, with palpable subcutaneous soft tissue mass, it can lead to spontaneous pain, cramp, local tenderness or potentially neuropathic symptoms.
