Ergonomic glove pattern drafting method for hand assistive devices: considering 3D hand dimensions and finger mobility

Recently, interest has surged in glove-type assistive devices for relieving hand muscle stiffness caused by brain lesions. This study aims to develop an ergonomic method for drafting glove patterns intended for hand-assistive devices. To facilitate pattern development, we acquired three-dimensional (3D) scan data from the four hemiplegic patients while their hands were in a relaxed posture, which was subsequently transformed into two-dimensional (2D) data. Based on the 3D shape data, we analyzed the finger joint range of motion (ROM) and change ratio of skin surface length resulting from flexion and extension movements of the paralyzed hand. Incisions were strategically applied to regions displaying significant variations in these parameters. These flattened 2D patterns were then integrated into revised pattern blocks to enhance the shading data related to the 3D shape, resulting in the development of four glove patterns. We found that gloves prototyped using this innovative pattern-drafting method did not impede joint ROM when worn. Changes in clothing pressure inside the glove at the joints corresponded to the bending angles of the fingers, and the pressure did not exceed the discomfort threshold during hand flexion and extension movements. Importantly, participants provided positive subjective feedback concerning the comfort of the gloves. Our findings yield fundamental data for developing a foundational glove design for hand-assisted devices for patients with paralysis, achieved through the utilization of this novel ergonomic glove pattern-drafting method.

Anthropometric survey of dynamic hand dimensions: A pilot study

IntroductionEffective glove design requires understanding hand dimensions and movement. Designers must study hands in static and dynamic postures. They do this to identify key movement points. This study aimed to determine hand size during motion. The goal was to understand and specify how hand shape changes. Methods and materialsThirty dynamic hand dimensions of 100 Iranian males were measured in six postures using photography and three-dimensional modeling. The data were classified and compared based on hand positions. ResultsThe results showed significant differences in hand size during movements. Four hand.dimensions were found to have significant differences (p > 0.05) related to hand posture. Sizes either decreased or increased significantly. The dorsal hand length underwent a significant alteration. This was compared to the palmar hand length during movement. ConclusionThe results of this study help to design gloves with optimal fit, performance and comfort. The results show that the dorsal hand length should be increased, while the palmar hand length should be decreased in the design of the glove pattern. Gloves that are currently made based on static postures cannot provide a good fit. Attention should be paid to the measurement of the hand in dynamic positions.

A review on comparative study of effectiveness of pregabalin and carbamazepine in painful diabetic peripheral neuropathy using mc gill's pain questionnaire

Diabetic neuropathy is a unique degenerative disorder of the peripheral nervous system that preferentially targets sensory axons and autonomic axons. The loss of sensory function that begins distally in the lower extremities is known as Diabetic neuropathy. It is characterized by burning pain, paresthesias and numbness in stocking glove pattern that progress proximally from the feet and hands. Diabetic neuropathy is a highly prevalent condition that substantially affects patients by increasing falls causing pain and reducing quality of life. The major risk factors for diabetic neuropathy is hyperglycemia. In addition to poor glycemic control, more-severe symptoms of diabetic neuropathy are associated with advanced age, hypertension, the duration of diabetes, dyslipidemia, smoking and heavy alcohol intake. Diabetic neuropathy is a major cause for disability of feet and hands globally. Anti-convulsants like pregabalin and carbamazepine are the medications used in the treatment of painful diabetic neuropathy.

Late presentation of combined hamartoma of retina and retinal pigment epithelium with a boxing glove pattern: A case report

Combined hamartoma of retina and retinal pigment epithelium (CHRRPE) is a rare intraocular tumor of the posterior pole associated with multiple genetic syndromes. We report a late-presenting unilateral CHRRPE in a 58-year-old male with complains of gradual, painless, and progressive diminution of vision. Optical coherence tomography showed altered retinal architecture in the involved area. Furthermore, evaluation revealed vascular telangiectasia with abnormal ocular fluorescence on fundus fluorescein angiography. CHRRPE may lead to formation of epiretinal membranes, holes, and neovascular membranes in the retina. Therefore, early diagnosis and prompt management is essential. Through this case, we would like to emphasize the need of understanding the pathogenesis of CHRRPE and whether these isolated ocular lesions can be a diagnostic sign of associated genetic syndromes.

Single-fiber Electromyography in Patients with Diabetic Neuropathy

Diabetic peripheral neuropathy (DPN) is the most common microvascular complication of diabetes mellitus. Clinically, it affects the most distal extremities, first resulting in a stock and glove pattern of sensory loss. It affects both small fibers (myelinated and unmyelinated) and large myelinated nerve fibers. However, the earliest manifestations might be due to small fiber dysfunction. The diagnosis of DPN relies largely on typical history and physical examination and supported by the conventional nerve conduction study (NCS) and electromyography (EMG). However, a large number of cases might be missed from diagnosis due to small fiber involvement that manifests before large fibers. This necessitates the use of other diagnostic strategies such as single-fiber EMG, which is helpful in deciphering small fiber dysfunction and DPN earlier than NCS.

Impact of postural variation on hand measurements: Three-dimensional anatomical analysis.

In this article, the impact of postural variations on hand anthropometry and distribution of skin strain ratios has been investigated. The literature suggests the glove fit directly affects hand functions. However, gloves currently manufactured based on a static posture failed to provide optimum fit. Workers often do not wear protective gloves due to discomfort caused by improper design, which increases the risk of hand injury. Full-color three-dimensional scans of the hands are captured with thirty healthy subjects (20 females, 10 males) to analyze the hand measurements and skin deformation with various postures. 42 of the 57 hand dimensions were found to have significant differences (p >0.05) related to hand posture. The skin strain ratios further suggest that the slant of the web space, dorsal-length and surface area should be increased, while the angles of the web space and length of the palm reduced to advance glove patterns. This research contributes to constructing gloves with optimum fit, performance, and comfort. Results show that in consideration of hand postures, the angle of the slant of web space between digits 2 and 5 and the finger length on the dorsal side should be increased, whilst the finger length on the palm side should be reduced in glove pattern design. Gloves currently constructed based on a splayed posture cannot provide a good fit. Consideration should be given to hand measurements in dynamic postures.

Method to Develop a Better Performance Glove Pattern Block Using 3d Hand Anthropometry

Fit challenges exist for performance glove users, because the methods of collecting anthropometric hand data and glove patterning have not been updated in unison. This paper will demonstrate a new method to draft a better basic performance glove pattern block from more relevant hand anthropometric data. The method may be used by product/industrial design educators, professional designers, patternmakers and manufacturers to develop better fitting and functioning gloves.

Automatic Hand Measurement System from 2D Hand Image for Customized Glove Production

Recent advancements in optics technology enable us to realize fast scans of hands using two-dimensional (2D) image scanners. In this paper, we propose an automatic hand measurement system using 2D image scanners for customized glove production. To develop the automatic hand measurement system, firstly hand scanning devices has been constructed. The devices are designed to block external lights and have user interface to guide hand posture during scanning. After hands are scanned, hand contour is extracted using binary image processing, noise elimination and outline tracing. And then, 19 hand landmarks are automatically detected using an automatic hand landmark detection algorithm based on geometric feature analysis. Then, automatic hand measurement program is executed based on the automatically extracted landmarks and measurement algorithms. The automatic hand measurement algorithms have been developed for 18 hand measurements required for custom-made glove pattern making. The program has been coded using the C++ programming language. We have implemented experiments to demonstrate the validity of the system using 11 subjects (8 males, 3 females) by comparing automatic 2D scan measurements with manual measurements. The result shows that the automatic 2D scan measurements are acceptable in the customized glove making industry. Our evaluation results confirm its effectiveness and robustness.

Recent Updates on Chemotherapy-Induced Peripheral Neuropathy

Chemotherapy induced peripheral neuropathy (CIPN) could debilitate the quality of life in the patients with cancer. According tothe severity of CIPN, the modification of dosage of chemotherapeutic agents and switch to other drugs can be unavoidable. Platinum such as cisplatin and oxalipatin, vinka alkaloids, bortezomib, and taxane can cause CIPN. The characteristics and severityof CIPN depends on the dosages, duration of exposure of chemotherapeutic agents, comcomittant illness or other drugs affecting onperipheral nervous system and the methods of assessment for CIPN. The symptoms may last for several months or permanentlyeven after quitting chemotherapy. Typically it distributed bilaterally and starts from the distal part of extremities and is presentedprogressively in stocking and glove pattern. Sensory nerve is more involved rather than motor nerve and amplitude of sensorynerve conduction is observed in CIPN. Prevention for CIPN is not effective at present. Tricyclic antidepressant including amitriptylineor nortriptyline and gabapentine have been tried in the practice for the management of CIPN despite of the lack of significantevidence through clinical trials. Recently duloxetine has been reported to decrease pain in the patients with CIPN compared with thepatients with placebo (p = 0.03).

Skin Deformation Behavior during Hand Movements and their Impact on Functional Sports Glove Design

In this study a three-dimensional (3D) INFOOT scanner was used to scan the hand in different postures and Geomagic Studio 12 was used to measure and analyzes the skin deformation behavior (skin relaxed-strain ratio) during various sport activities. Thirteen female participants between the ages of 40-65 years with hand size medium (M) performed a relaxed hand posture and two dynamic postures which were relevant to key sport activities. There were significant differences in the skin relaxed-strain ratio between the experimental postures, especially in phalangeal and metacarpal regions with exception in (third finger-metacarpal region). The results of this study suggest that the metacarpal region had significantly larger skin relaxed-strain ratio than the phalangeal region and metacarpal-carpal region. This study has contributed to enhancing the knowledge of the skin deformation behavior during various sports activities which could be incorporated into sports and functional glove pattern design and engineering for improving the fit, comfort, and functionality of a sport glove.

Ex-vivo training model for laparoendoscopic single-site surgery

BACKGROUND:Laparoendoscopic single-site surgery (LESS) has recently been applied successfully in the performance of a host of surgical procedures. Preliminary consensus from the experts is that this mode of surgery is technically challenging and requires expertise. The transition from trainee to practicing surgeon, especially in complex procedures with challenging learning curves, takes time and mentor-guided nurturing. However, the trainee needs to use platforms of training to gain the skills that are deemed necessary for undertaking the live human case.OBJECTIVE:This article aims to demonstrate a step-by-step means of how to acquire the necessary instrumentation and build a training model for practicing steeplechase exercises in LESS for urological surgeons and trainees. The tool built as a result of this could set the platform for performance of basic and advanced skills uptake using conventional, bent and articulated instruments. A preliminary construct validity of the platform was conducted.MATERIALS AND METHODS:A box model was fitted with an R-Port™ and camera. Articulated and conventional instruments were used to demonstrate basic exercises (e.g. glove pattern cutting, loop stacking and suturing) and advanced exercises (e.g. pyeloplasty). The validation included medical students (M), final year laparoscopic fellows (F) and experienced consultant laparoscopic surgeons (C) with at least 50 LESS cases experience in total, were tested on eight basic skill tasks (S) including manipulation of the flexible cystoscope (S1), hand eye coordination (S2), cutting with flexible scissors (S3), grasping with flexible needle holders (S4), two-handed maneuvers (S5), object translocation (S6), cross hand suturing with flexible instruments (S7) and conduction of an ex-vivo pyeloplasty.RESULTS:The successful application of the box model was demonstrated by trainee based exercises. The cost of the kit with circulated materials was less than £150 (Pounds Sterling). The noncamera handling skills (S2–S8) of the ex-vivo training model for LESS can distinguish between laparoscopically naïve fellows and experienced consultants in LESS. S4–S8 showed the highest level of construct validity, by accurately differentiating among the M, F and C groups.CONCLUSION:LESS requires a significant amount of skill and has an inherent steep learning curve. The ex-vivo model described provides a cost-effective means that a trainee or training unit can build for optimising preliminary skill acquisition in LESS for urological trainees. It has construct validity in several tasks. Such platform models should be tested further with an emphasis on rapid sequence uptake of optimal skills, prior to undertaking the live human case.

A Study on the Measurement of Korean Hand - Focusing on Glove & Hand Dimension -

The purpose of this study was to develop the dimension of hand pattern-making for Korean glove. The glove pattern-making has difficult problem in combination of anthropometric and engineering aspects. In addition, existing dimension data are not enough for glove pattern-making. Therefore, to develop the dimension for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over the 15 years) were interviewed on the method of glove. The result of comparing between the structures in hand and existing glove pattern, there draw deduction from follows. Pattern-making for glove need size of hand length, thumb length, index finger length, middle finger length, ring finger length, hand circumference, thumb-ring finger circumference and maximum hand thickness.

Abnormally increased uptake of 18F-FDG in the forearm and hand following intra-arterial injection — hot forearm and hot hand signs

The aim of this study is to describe the appearance of intra-arterial administration of 18F-fluorodeoxyglucose (18F-FDG). The effect of this finding on the standard uptake values (SUVs) is also briefly discussed. Three cases of 18F-FDG positron emission tomography (PET) scans, detected over 2 years (2004-2006), with different presentations producing hot forearm and hot hand signs are described. It was shown that intra-arterial injections of 18F-FDG producing "the hot forearm sign" and the hot hand sign" are similar to the glove pattern of uptake noted following intra-arterial administration of technetium-99m methylene diphosphonate. Following intra-arterial injection, uptake of 18F-FDG is accentuated by hypoxia and exercise. A comparison is also made with the pattern of soft-tissue uptake seen following true intravenous injections with similar pre-injection vein enhancement techniques to the intra-arterial injections. Evaluation of the maximum intensity projection (MIP) and transaxial PET/CT fusion images of the arm, forearm and hand helps to confirm the diagnosis. Hands are often not included in PET/CT imaging and therefore cases might be missed. In conclusion, intra-arterial injection of 18F-FDG produces a "hot forearm sign" and "hot hand sign". Hands are often not included in PET/CT imaging, and therefore the presence of hot forearm sign should suggest further investigation. It should be mentioned in the radiology report, as it may alter the sensitivity and specificity of the SUV value.

3차원 데이터를 활용한 장갑형 햅틱(Haptic)용 기본 패턴 개발

Tight fitting glove pattern is necessary to convey oscillation to the skin from the sensors attached on the hands as found in the haptic device. However, it has been difficult to provide customized glove pattern for haptic device so far. The objective of the paper is to develop a 2D pattern that fit tightly to hands by adopting the recent 3D technology to the clothing science. In this study, the user graphic interface application software(2C-AN) for the semi-automatic garment pattern generation has been utilized to develop the methodology of construct tight-fitting glove pattern for the hand in natural position. A basic pattern was developed directly from the 3D images of hand and the verification of the proposed pattern was also provided.

Case Report: Painful Peripheral Neuropathy Following Treatment With Docetaxel for Breast Cancer

Peripheral neuropathy is a common side effect of many chemotherapy agents. As many as 60% of patients receiving taxane therapy report symptoms such as numbness, tingling, burning, pain, and, in severe cases, weakness in a stocking and glove pattern. These symptoms are associated with problems in physical mobility and decreased quality of life, yet few articles in the literature discuss collaborative interdisciplinary assessment and treatment of this population. This article describes the care of a patient with diabetes and docetaxel-induced, painful peripheral neuropathy by a multidisciplinary team of nurses, physicians, and physical therapists. Because nurses are often the first clinicians to recognize symptoms of chemotherapy-induced peripheral neuropathy, they provide the essential coordination of care by appropriate medical and rehabilitative services. This case also raises important questions about the relationship between diabetes mellitus and persistent, painful peripheral neuropathy.
