Three-dimensional Printed Hand Orthoses

Three-dimensional Printed Orthoses for Improving Daily Functioning in Chronic Hand Conditions

In persons with chronic hand conditions, orthoses are often prescribed to improve daily-life functioning. In most cases, orthoses are custom manufactured based on a plaster hand model, which is a time-consuming and labor-intensive process. It has been demonstrated that the production time to custom manufacture hand orthoses can be greatly reduced by using three-dimensional (3D) scanning and printing, offering a promising cost-effective alternative to conventional costum manufactured hand orthoses. However, before setting up a cost-effectiveness study in persons with chronic hand conditions, insight into the effectiveness of 3D-printed orthoses on performance of activities of daily living (ADL) is needed, as well as insight into potential cost reductions. To date, this information is largely unknown. The aims of this feasibility study are 1) to collect data on the preliminary effectiveness of 3D-printed orthoses on performance of ADL, satisfaction with the orthosis and quality of life compared to conventional orthoses in persons with chronic hand conditions, and 2) to compare the production time and costs of 3D-printed orthoses with conventional orthoses.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in performance of ADL on the custom short form of the Dutch-Flemish Patient-Reported Outcomes Measurement Information System - Upper extremity (DF-PROMIS-UE) at 4 months post-intervention.	The short form DF-PROMIS-UE contains 25 items from the DF-PROMIS-UE 46-item bank. Patients will rate how easily they can perform each activity on a 5-point scale, ranging from "without any difficulty" (score 4 or 5) to "unable to do" (score 1). For each activity, the question was added whether participants use their orthosis for that specific activity. The total score will be expressed as a T-score, which is a standardized score, with 50 representing the average score of the US general population and 10 being its standard deviation (SD). Note. For this study, the reliability of the DF-PROMIS-UE in persons with chronic hand conditions will be determined.	2 weeks pre-intervention; baseline; 1 month post-intervention; 4 months post-intervention

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in performance of ADL, overall hand function, pain, work, performance, aesthetics, and satisfaction on the Michigan Hand Questionnaire-Dutch Language version (MHQ-DLV) at 4 months post-intervention.	MHQ-DVL domain items are scored from 0 - 100, in which 100 is the best possible ability, while for pain a score of 0 indicates no pain. The total MHQ-DLV score is calculated as the mean of all 6 domains (after converting pain from a "best score of 0" scale to a "best score of 100" scale). Note. For this study, the reliability of the MHQ-DLV in persons with chronic hand conditions will be determined.	2 weeks pre-intervention; baseline; 1 month post-intervention; 4 months post-intervention
Change from baseline in satisfaction assessed with the Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology (D-QUEST) at 4 months post-intervention	The D-QUEST assesses satisfaction with aspects related to the device and provided services. For this study, only the device-part of the D-QUEST will be used, which comprises 8 questions about certain characteristics of the orthotic device, all scored on a 5-point scale (from 'not satisfied at all' to 'very satisfied'), with a total score ranging from 8-40 (with 40 being the best possible satisfaction score).	Baseline; 1 month post-intervention; 4 months post-intervention
Change in quality of life on the 5-dimension 5-level EuroQol (EQ-5D-5L) at 4 months post-intervention.	The EQ-5D-5L contains five questions about mobility, self-care, usual activities, pain/discomfort, and anxiety and depression scored on a 5-point scale indicating the degree of problems with each dimension and one question about experienced health scored on a 0-100 visual analogue scale.	Baseline; 1 month post-intervention, 4 months post-intervention
Production time of the orthosis (in minutes).	For each step in manufacturing the orthosis until final delivery, time will be recorded (with a stopwatch).	From start of the intervention up to delivery of the orthosis
Production costs of the orthosis (in euro).	Costs of the conventional orthoses will be retrospectively inventoried from the administration records of OIM. Costs related to the manufacturing of the 3D-printed orthoses will be prospectively assessed.	From start of the intervention up to delivery of the orthosis
Change from baseline in personal goals at 4 month post-intervention.	An in-house usability questionnaire will be used to inventory information on personal goals of the orthosis, and whether this goal has been achieved (scored on a 10-point-scale, ranging from 1: not achieved at all to 10: very well achieved).	Baseline; 1 month post-intervention, 4 months post-intervention
Change from baseline in orthosis use at 4 month post-intervention.	An in-house usability questionnaire will be used to inventory how often the orthosis is used, classified in 5 categories; ranging from never until 6-7 days a week.	Baseline; 1 month post-intervention, 4 months post-intervention
Patient and therapist experiences with the 3D orthosis	Experiences of patients and health care providers with respect to the time window of the 3D intervention and satisfaction with the treatment process will be assessed with an in-house questionnaire, with items scored on a 5-point Likert scale.	1 month post-treatment
Number of visits for fabrication of the 3D orthosis	The total number of visits for fabricating the 3D orthosis will be obtained from the administration records of OIM	From start of the intervention up to delivery of the orthosis
Change from baseline in satisfaction assessed with the Dutch version of the Client Satisfaction with Device (CSD) module of the Orthotics and Prosthetics User's Survey (OPUS) at 4 months post-intervention.	The CSD contains 9 items rated on a 5-point Likert scale ranging from 0 ('strongly disagree') to 4 ('strongly agree), with a total score ranging from 0-36. Since the CSD is not yet available in Dutch, the investigators will translate it into the Dutch language and assess its content validity, structural validity, and reliability in Dutch orthotic users.	2 weeks pre-intervention; baseline; 1 month post-intervention; 4 months post-intervention
