Abstract Background: Use of standardized and scientifically sound outcome measures is highly encouraged in clinical practice and research. Researchers have identified that with the development of newer rehabilitation therapies we need technology-supported upper extremity outcome measures that are easily accessible and can measure change consistently and reliably. 3‐dimensional printing (3D-printing) has recently seen a meteoric rise in interest within medicine including the field of Physical Medicine and Rehabilitation. The primary objective of the current study was to evaluate the feasibility of designing and constructing a 3D printed version of the Toronto Rehabilitation Institute-Hand Function Test (TRI-HFT). The secondary objective was to assess the preliminary psychometrics of the 3D TRI-HFT in individuals with stroke. Results: 3D design files were created using the measurements of the original TRI-HFT objects. The 3D printed objects were then compared to the original test objects to ensure that the original dimensions were preserved. All objects were successfully printed except the sponge and paper which required some modification. The error margin for weight of the objects was within 10% for the rest of the objects. Nine participants underwent the following assessments: the Chedoke Arm and Hand Activity Inventory (CAHAI), Fugl Meyer Assessment-Hand (FMA-Hand), Chedoke McMaster stages of recovery of the arm (CMSA-Arm) and Chedoke McMaster stages of recovery of the hand (CMSA-Hand) and the 3D TRI-HFT for assessment of psychometric properties of the test. The video recorded assessment of the 3D TRI-HFT was reviewed by two assessors for reliability testing. Construct validity was assessed by comparing the scores on 3D TRI-HFT with the scores on CAHAI, CMSA-Arm, CMSA-Hand and FMA-Hand. The 3D TRI-HFT had high inter-rater reliability (ICC of 0.99; P < 0.000), high intra-rater reliability (ICC of 0.99; P < 0.000) and moderate to strong correlation with the CMSA-Arm, CMSA-Hand and FMA-Hand scores. Conclusions: The TRI-HFT could be successfully 3D printed and initial testing indicates that the test is a reliable and valid measure of upper extremity motor function in individuals with stroke.

INTRODUCTION 3D printing for non‐weight‐bearing upper extremity prostheses is becoming increasingly popular as a method of fabrication.1 Some clinics in North America have begun using 3D printing to fabricate lower extremity diagnostic sockets (Figure 1). The strength requirements for upper extremity prostheses are not as rigorous as the strength requirements for lower extremity prostheses. Therefore, strength testing on 3D-printed lower extremity sockets is one of the first steps that needs to be conducted to ensure patient safety. 3D-printed prosthetic sockets are becoming an alternative option to traditional methods because it is possible to customize different parameters to create a strong structure. Infill percentage is an important parameter to research as this can have an influence on the strength of 3D printed sockets.2 As both prosthetists and healthcare professionals, there is a need to become more involved in the process of designing and testing 3D printed sockets. The purpose of this study is to test how changing the infill percentage affects the ultimate strength of a 3D printed transtibial socket during initial contact.

Upper Limb Prosthetics

INTRODUCTION Additive Manufacturing (AM), colloquial known as 3D-printing, has been deemed capable to revolutionize a great number of industries, including the Health Care industry.1 In the field of upper limb prosthetics, it has been attempted to leverage the potential advantages of AM, such as crowd based design optimization, infrastructure independent fabrication, and economical material use, in the interest of providing low-cost, readily available devices to recipients whose needs were only insufficiently met by traditional approaches of device prescription and fitting. While the popular media has been quick to emphasize the potential – perceived or real – of 3D printed prostheses, clinicians have generally been less euphoric and the base of scientific evidence on questions related to these applications has been small.2 As with most research endeavors in prosthetics and orthotics, recruiting sufficient sample sizes to allow solid conclusions is a perennial challenge also in this sub-field. As a consequence, the effectiveness of the many 3D-printed upper limb devices made by volunteers of the E-nable community (Fig.1) is yet to be determined. Self-reported outcome assessment tools can somewhat mitigate the issue of low sample sizes. However, none have been applied to a wider range of device classes, to allow comparative analyses across those. We describe the development and preliminary testing of an online based survey tool to generate comparison outcome data for a wide variety of upper limb prosthetics devices, including varieties that are 3D-printed by hobbyists.

Abstract Background Use of standardized and scientifically sound outcome measures is encouraged in clinical practice and research. With the development of newer rehabilitation therapies, we need technology-supported upper extremity outcome measures that are easily accessible, reliable and valid. 3‐Dimensional printing (3D-printing) has recently seen a meteoric rise in interest within medicine including the field of Physical Medicine and Rehabilitation. The primary objective of this study was to evaluate the feasibility of designing and constructing a 3D printed version of the Toronto Rehabilitation Institute-Hand Function Test (TRI-HFT). The TRI-HFT is an upper extremity gross motor function assessment tool that measures function at the intersection of the International Classification of Function’s body structure and function, and activity domain. The secondary objective was to assess the preliminary psychometrics of this test in individuals with stroke. Results 3D design files were created using the measurements of the original TRI-HFT objects. The 3D printed objects were then compared to the original test objects to ensure that the original dimensions were preserved. All objects were successfully printed except the sponge and paper which required some modification. The error margin for weight of the objects was within 10% of the original TRI-HFT for the rest of the objects.

The video recorded assessment of the 3D TRI-HFT was used for reliability testing. Construct validity was assessed by comparing the scores on 3D TRI-HFT with the scores on CAHAI, CMSA-Arm, CMSA-Hand and FMA-Hand. The 3D TRI-HFT had high inter-rater reliability (Intra-Class Correlation Co-efficient (ICC) of 0.99; P < 0.000), high intra-rater reliability (ICC of 0.99; P < 0.000) and moderate-to-strong correlation with the CMSA-Arm, CMSA-Hand and FMA-Hand scores. Conclusions The TRI-HFT could be successfully 3D printed and initial testing indicates that the test is a reliable and valid measure of upper extremity motor function in individuals with stroke.

Wide tumor resection is the local treatment of choice for patients with primary malignant bone tumors and a prerequisite for long-term survival. We present two patients that underwent total bone resection in the upper limb because of primary malignant bone tumors. The defects were then reconstructed by a 3D printed prosthesis, a procedure that, to our knowledge, has not been reported for bone defects of the upper extremity so far. Complete resection of the affected bone was required in a five-year-old girl with a high-grade osteoblastic osteosarcoma of the humerus and a 53-year-old man with a dedifferentiated leiomyosarcoma of the radius, due to the tumor’s extent. Following neoadjuvant chemotherapy, resection of the entire affected humerus including the axillary nerve took place in the first case and the entire affected radius including parts of the radial nerve in the second case. Approximately three years after surgery, both patients are alive and pain-free. Despite a postoperative drop hand that affected the now 56-year-old man, he is able to carry out everyday activities such as brushing his teeth, writing, and eating. The now eight-year-old girl is also able to engage in normal activities with her left arm such as eating and carrying lightweight objects. Both patients are tumor-free to date.
