Background: The objective of this study was to determine the functionality of 3-dimensional (3D) printed orthoses for upper extremity immobilization compared with conventional immobilization. Methods: Twelve healthy volunteers were fitted with a 3D custom printed short arm cast and a short arm fiberglass cast in separate sessions. The Jebsen Hand Function Test (JHFT) was used to test function and dexterity in each cast. All volunteers completed a modified version of the Patient-Rated Wrist Evaluation (PRWE). Skin complications were recorded. Results: There were no significant differences during the JHFT between casts, although one-third of the participants in the 3D cast could perform the tasks in a normal time, which they could not in the fiberglass cast. The average PRWE function score was lower in the 3D cast group than in the fiberglass group (45.5 vs. 80.8). Minor skin irritation was noted in 42% of patients in the fiberglass cast group compared with only 1 patient (8%) in the 3D cast group. One patient in the fiberglass group required a cast change due to inappropriate fit. Conclusions: Both casting techniques demonstrate similar objective function based on the JHFT. Patient satisfaction, comfort, and perceived function are superior in the 3D printed casts.

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.

Hands are the most frequent burn injury sites. Appropriate rehabilitation is essential to ensure good functional recovery. Virtual reality (VR)-based rehabilitation has proven to be beneficial for the functional recovery of the upper extremities. We investigated and compared VR-based rehabilitation with conventional rehabilitation (CON) in patients with burned hands. Fifty-seven patients were randomized into a VR or CON group. Each intervention was applied to the affected hand for four weeks, and clinical and functional variables were evaluated. Hand function was evaluated before intervention and four weeks after intervention using the Jebsen-Taylor hand function test (JTT), Grasp and Pinch Power Test, Purdue Pegboard test (PPT), and Michigan Hand Outcomes Questionnaire (MHQ). The JTT scores for picking up small objects and the MHQ scores for hand function, functional ADL, work, pain, aesthetics, and patient satisfaction were significantly higher in the VR group than in the CON group (p < 0.05). The results suggested that VR-based rehabilitation is likely to be as effective as conventional rehabilitation for recovering function in a burned hand. VR-based rehabilitation may be considered as a treatment option for patients with burned hands.

Background Acquiring proficiency for the repair of a cerebrospinal fluid (CSF) leak is challenging in great part due to its relative rarity, which offers a finite number of training opportunities. Objective The purpose of this study was to evaluates the use of a 3-dimensional (3D) printed, anatomically accurate model to simulate CSF leak closure. Methods Volunteer participants completed two simulation sessions. Questionnaires to assess their professional qualifications and a standardized 5-point Likert scale to estimate the level of confidence, were completed before and after each session. Participants were also queried on the overall educational utility of the simulation. Results Thirteen otolaryngologists and 11 neurosurgeons, met the inclusion criteria. A successful repair of the CSF leak was achieved by 20/24 (83.33%), and 24/24 (100%) during the first and second simulation sessions respectively (average time 04:04 ± 1.39 and 02:10 ± 01:11). Time-to-close-the-CSF-leak during the second session was significantly shorter than the first (p < 0.001). Confidence scores increased across the training sessions (3.3 ± 1.0, before the simulation, 3.7 ± 0.6 after the first simulation, and 4.2 ± 0.4 after the second simulation; p < 0.001). All participants reported an increase in confidence and believed that the model represented a valuable training tool. Conclusions Despite significant differences with varying clinical scenarios, 3D printed models for cerebrospinal leak repair offer a feasible simulation for the training of residents and novice surgeons outside the constrictions of a clinical environment.

Abstract Hands are the part of the body that are most commonly involved in burns, and the main complications are finger joint contractures and nerve injuries. Hypertrophic scarring cannot be avoided despite early management of acute hand burn injuries, and some patients may need application of an exoskeleton robot to restore hand function. To do this, it is essential to individualize the customization of the robot for each patient. Three-dimensional (3D) technology, which is widely used in the field of implants, anatomical models, and tissue fabrication, makes this goal achievable. Therefore, this report is a study on the usefulness of an exoskeleton robot using 3D technology for patients who lost bilateral hand function due to burn injury. Our subject was a 45-year-old man with upper limb dysfunction of 560 days after a flame and chemical burn injury, with resultant impairment of manual physical abilities. After wearing an exoskeleton robot made using 3D printing technology, he could handle objects effectively and satisfactorily. This innovative approach provided considerable advantages in terms of customization of size and reduction in manufacturing time and costs, thereby showing great potential for use in patients with hand dysfunction after burn injury.

Abstract Background The first FDA-cleared, long-lasting, minimally invasive device for improving the appearance of cellulite was recently launched in Canada as a novel, tissue stabilized–guided subcision (TS-GS) system (Cellfina, Merz North America, Inc., Raleigh, NC). Clinicians from 2 of the first Canadian sites offering this procedure were interested in evaluating treatment efficacy and patient satisfaction after its first year on the market. Objectives The authors sought to evaluate the efficacy of TS-GS and the level of patient satisfaction associated with the procedure. Methods Medical charts of female patients treated with the TS-GS system in 2017 were retrospectively analyzed at 2 Canadian centers. Measurements at baseline and 3 months posttreatment were assessed for patient satisfaction and physician-rated efficacy. Patient satisfaction was assessed using a 5-point Likert-type scale, and efficacy was evaluated through physician review of 2-deminsional and 3-dimensional photography, the Nürnberger-Müller Scale for cellulite, and the Global Assessment of Improvement Scale. Results We reviewed 25 patient charts. At month 3, 95.6% of patients were satisfied with treatment results and physician evaluations revealed that on average, patients displayed a 1-point improvement in their cellulite grades. Moreover, Global Assessment of Improvement Scale scores indicated that all patients had visible improvement in the global appearance of cellulite. No serious adverse events were observed within 3 months postprocedure. Conclusions The physician ratings, patient satisfaction, and photographic evidence support the efficacy of the TS-GS system to manage grades 1 to 3 cellulite in women’s thighs and buttocks. These findings indicate the safety of the TS-GS system. Level of Evidence: 4

ABSTRACT The sterilization chamber is designed to sterilize the body using a filler formulation that is not harmful to the skin surface. Formulation, namely the composition of filler fluids (type, dose and amount) using substances that are safe for the body accordingly, certainly provides benefits. The use of the sterilization booth uses the correct and safe filling fluid. The sterilization chamber uses a mist nozzle sprayer (with the appropriate discharge) to spray the filling liquid so that the user is safe. This sterilization booth is named "White Box". This "White Box" research aims to design (functional and structural) and test (function test and performance test) on a system and mechanism for condensing the condensation of a humidifier that can fill the sterilization room optimally. The design method of the "White Box" sterilization booth uses a qualitative method with the following phases: (1) The preparation stage, namely the functional design and the structural design of the "White Box"; (2) The implementation stage is analyzing the use of tools and materials and making sterilization booths; (3) Post-implementation stage, namely testing the sterilization chamber, including the function test and performance test of the sterilization chamber. The design activity of the "White Box" sterilization booth was carried out by testing various variations of the prototype, including variations in the dimensions of the distribution pipe, the shape of the distribution pipe, and variations of the piping system. The validation process includes: (1) The diameter of the pipe against humidifier dew bursts; (2) The shape of the piping against humidifier dew spray; and (3) the length of the pipe passage to the humidifier dew spray.
