ASST Carlo Poma Mantova.

The background and the aim of the work: The Department of Orthopedics and Traumatology of the "Carlo Poma" Hospital (Social Territorial Health Authority of Mantova), has pointed out in 2017, through the questionnaires survey over the citizens satisfaction, an appreciation decrease compared to the previous years. The obtained data were not sufficiently explanatory of the reasons for that kind of deterioration and also not enough specific to define possible corrective measures. The aim of this work was to identify the patients' perception regarding the hospitalization phases (from booking to follow up), taking into account five kind of operations and pathologies: 1st knee, shoulder and tibio-talar arthroscopy; 2nd hip and knee prosthesis; 3rd upper limb traumatology; 4th lower limb traumatology and 5th orthogeriatrics.

Ten guidelines for the design of non-assembly mechanisms: The case of 3D-printed prosthetic hands.

Proc Inst Mech Eng H 2018 Sep 16;232(9):962-971. Epub 2018 Aug 16.

Department of Biomechanical Engineering, Faculty of Mechanical, Maritime and Materials Engineering, Delft University of Technology, Delft, The Netherlands.

In developing countries, prosthetic workshops are limited, difficult to reach, or even non-existent. Especially, fabrication of active, multi-articulated, and personalized hand prosthetic devices is often seen as a time-consuming and demanding process. An active prosthetic hand made through the fused deposition modelling technology and fully assembled right after the end of the 3D printing process will increase accessibility of prosthetic devices by reducing or bypassing the current manufacturing and post-processing steps.

Test-Retest Reliability of Dynamic Balance Performance-Based Measures Among Adults With a Unilateral Lower-Limb Amputation.

PM R 2019 Mar 7;11(3):243-251. Epub 2019 Mar 7.

Department of Physical Therapy, Delaware Limb Loss, University of Delaware, 540 S. College Ave., Suite 210JJ, Newark, DE 19713.

Background: There is large variation in administration of performance-based, dynamic balance measures among adults with lower-limb amputation (LLA). Further, there has been limited exploration of test-retest reliability of these measures in adults with lower-limb loss, including whether there is a difference in reliability if one records "best" vs "average" performance across trials.

Objective: To determine test-retest reliability of several balance tests for both "best" and "average" score performance in community-dwelling adults with a unilateral LLA, including quantification of the precision of individual scores (SE of the measurement, SEM) and estimates of minimal detectable change (MDC ).

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
