“…However, relatively thick vibration-reducing materials used in AV gloves generally impede hand performance in view of manual dexterity and grip strength. Wearing gloves usually requires a relatively higher grip exertion by the operators compared with bare hand (BH; Hamouda et al, 2018; Welcome et al, 2012; Willms et al, 2009; Wimer et al, 2009; Yao et al, 2019; Young et al, 2012; Yu et al, 2015). Higher grip strength demand can increase the risk of hand-arm musculoskeletal disorders (MSDs) among operators, such as hand tendonitis, strained muscles, and carpal tunnel syndrome (Chang & Shih, 2007; Silverstein et al, 1987; Wimer et al, 2010).…”

Assessing Increased Activities of the Forearm Muscles Due to Anti-Vibration Gloves: Construct Validity of a Refined Methodology

Objective The primary aim was to test the construct validity of a surface electromyography (EMG) measurement protocol, indirectly assessing the effects of anti-vibration (AV) gloves on activities of the forearm muscles. Background AV gloves impose a relatively higher grip demand and thus a higher risk for musculoskeletal disorders. Consequently, activities of the forearm muscles should be considered when assessing AV glove performance. Method Effects of AV gloves on activities of the forearm muscles (ECR: extensor carpi radialis longus; ED: extensor digitorum; FCR: flexor carpi radialis; FDS: flexor digitorum superficialis) were measured via EMG, while gripping a handle with two grip force levels. Fifteen subjects participated with 11 glove conditions, including one with bare hand. Results Activities of ECR, FCR, mean of ECR and FCR (ECR_FCR), and mean of all four muscles were sensitive to wearing gloves. Compared with bare hand, combined ECR_FCR activities increased by 22%–78% (mean = 48%, SD = 28%) with gloves. The correlation coefficient ( r) of ECR_FCR activities with glove thickness and manual dexterity scores were 0.74 ( p < .05) and 0.90 ( p < .001), respectively. Conclusions A refined EMG methodology was the most sensitive to AV gloves with specific forearm muscles (ECR and FCR) and the 50-N handgrip force. Its construct validity was further substantiated by correlations with glove thickness and manual dexterity. Application Assessment of the effect of AV gloves on activities of the forearm muscles can yield design guidance for AV gloves to reduce grip exertion by the gloved hand.

“…There is evidence that reducing the coupling force is likely to decrease the injurious effect of exposure to HTV. Moreover, greater grip and push forces yield increased electrical activities of the flexor carpi ulnaris and finger-flexor muscles, which may adversely affect peripheral circulation of the fingers (Gurram, Rakheja, & Gouw, 1995;Huesler, Maier, & Hepp-Reymond, 2000;Vigouroux, et al, 2007;Yu et al 2015).…”

Relationship among hand forces imparted on a viscoelastic hand-handle interface

2019

Design of a flexible thin-film hand sensor is presented for reliable measurements of the contact pressure/force distribution at a viscoelastic hand-handle interface, including the contact force developed by a gloved-hand grasping a tool handle. The static properties of the developed hand sensor were evaluated in terms of its drift, linearity, repeatability and hysteresis under global as well as local loads. The measured results revealed low hysteresis (<6%) and drift (≈2.9% over 30s), good linearity (r 2 =0.99) and repeatability (CoV=1.5%). Subsequently, an experiment was designed to establish a relationship among the grip, push and contact forces imparted on a flexible hand-handle interface. The hand-handle contact force was measured considering three interface conditions: (i) bare hand grasping an instrumented rigid handle (BH); (ii) hand grasping the instrumented handle covered by an anti-vibration material (MT); and (iii) gloved hand grasping the handle (GV). The measurements with each interface were conducting with five male subjects and nine combinations of grip (10, 30 and 50 N) and push (25, 50 and 75 N) forces. The measured data were analyzed via multiple linear regression method to explore relationships among the grip (F g ), push (F p ) and contact (F c ) forces for each hand-handle interface. The data were further analyzed to investigate the effect of anti-vibration (AV) gloves on the hand grip strength. The relationship obtained for the hand grasping a rigid handle showed good agreement with those in the reported studies, which verified the hand sensor feasibility for application to curved surfaces. The relationship obtained for the bare hand grasping the handle with flexible anti-vibration material, however, showed higher coefficients of grip (α g ) and push (α p ) forces compared to those observed with the rigid handle of the same diameter. A similar trend was also obtained for the gloved hand grasping the handle, which suggested higher grip strength demand II for a gloved hand (GV) and hand coupling a viscoelastic handle (MT) compared to the BH condition for realizing the same level of grip/push force combination.
