Phantom motor execution as a treatment for phantom limb pain: protocol of an international, double-blind, randomised controlled clinical trial.

BMJ Open 2018 Jul 16;8(7):e021039. Epub 2018 Jul 16.

Biomechatronics and Neurorehabilitation Laboratory, Department of Electrical Engineering, Chalmers University of Technology, Goteborg, Sweden.

Introduction: Phantom limb pain (PLP) is a chronic condition that can greatly diminish quality of life. Control over the phantom limb and exercise of such control have been hypothesised to reverse maladaptive brain changes correlated to PLP. Preliminary investigations have shown that decoding motor volition using myoelectric pattern recognition, while providing real-time feedback via virtual and augmented reality (VR-AR), facilitates phantom motor execution (PME) and reduces PLP.

Coactivation index of children with congenital upper limb reduction deficiencies before and after using a wrist-driven 3D printed partial hand prosthesis.

J Neuroeng Rehabil 2018 Jun 8;15(1):48. Epub 2018 Jun 8.

Department of Biomechanics, Biomechanics Research Building, 3D Printed Prosthetic, Orthotic & Assistive Devices, University of Nebraska, 6001 Dodge St, Omaha, NE, 68182, USA.

Background: Co-contraction is the simultaneous activation of agonist and antagonist muscles that produces forces around a joint. It is unknown if the use of a wrist-driven 3D printed transitional prostheses has any influence on the neuromuscular motor control strategies of the affected hand of children with unilateral upper-limb reduction deficiencies. Thus, the purpose of the current investigation was to examine the coactivation index (CI) of children with congenital upper-limb reduction deficiencies before and after 6 months of using a wrist-driven 3D printed partial hand prosthesis.

A systematic review of shock-attenuating componentry for lower limb amputees.

Prosthet Orthot Int 2018 Aug 19;42(4):367-377. Epub 2018 May 19.

2 The University of Melbourne, Melbourne, VIC, Australia.

Background: Shock-attenuating pylons are commonly fitted to prostheses in order to compensate for the anatomical and biomechanical shock-absorbing features of the lower limb removed upon amputation. However, studies concerning their shock-attenuating capacity are highly variable and, to date, have not yet been reviewed, making them difficult to interpret and apply in clinical practice.

Objectives: To synthesise and appraise the available literature examining the effectiveness of shock-attenuating pylons in attenuating shock upon limb loading compared to rigid pylons among lower limb amputees. Read More

Taxonomy of clinical encounters during the first 90 days post-delivery of an initial lower limb prosthesis.

Prosthet Orthot Int 2018 Oct 18;42(5):490-497. Epub 2018 May 18.

2 New England Orthotic & Prosthetic Systems, Branford, CT, USA.

Background: The incidence and etiology of prosthetic services utilization is poorly understood during the first 90 days post-delivery of the initial lower limb prosthesis. This period is of critical importance, as prevailing policy dictates limits on the reimbursement for certain services provided during this time period. The first step in understanding the financial ramifications of such policy is to examine the taxonomy behind clinical encounters during this tenuous time period. Read More

Kinetic and kinematic variables affecting trunk flexion during level walking in patients with lumbar spinal stenosis.

PLoS One 2018 10;13(5):e0197228. Epub 2018 May 10.

Department of Medical Research and Management for Musculoskeletal Pain, 22nd Century Medical and Research Center, The University of Tokyo, Tokyo, Japan.

Lumbar spinal stenosis causes cauda equina and nerve root compression, resulting in neurological symptoms. Although trunk flexion during level walking may alleviate these symptoms by enabling spinal canal decompression, some patients do not use this strategy. We aimed to identify the kinetic and kinematic variables that affect trunk flexion in patients during level walking. Read More

Management of lower limb amputations.

Br J Hosp Med (Lond) 2018 Apr;79(4):205-210

Consultant, Prosthetic Rehabilitation Unit, Royal National Orthopaedic Hospital, Middlesex.

The most common reason for lower limb amputations in the UK is peripheral arterial disease. A thoughtful approach to surgery, with consideration of optimal amputation level and residual limb shape, can improve prosthetic use and functional outcomes. Prosthesis socket design and fit, as well as use of appropriate components, must be considered in accordance with the patient's activity level and potential. Read More
