“…Activities that involve repetitive movements of the thumb (flexion, extension, and rotation), ulnar deviation of the carpal, and the use of scissors are all recognized as risk factors. Professional activities can be a cause among nurses [7] and endoscopists [8]. Overuse of the thumbs in females who send text messages from their cell phones has been reported [9], and sports-related activities can also be considered risk factors (e.g., among volleyball players) [10].…”

Tenosynovitis refers to an inflammatory condition involving the synovial sheath of a tendon. Stenosing tenosynovitis is a peculiar entity caused by multiple factors, including local anatomy, mechanical factors, and hormonal factors. The main forms include de Quervain tendinopathy; trigger finger (stenosing tenosynovitis involving the flexor digitorum tendons); stenosing tenosynovitis of the extensor carpi ulnaris, extensor carpi radialis, or extensor comunis tendons; stenosing tenosynovitis of the flexor hallucis tendon; and stenosing tenosynovitis of the peroneal tendons. The cardinal finding on ultrasonography is the presence of a thickened retinaculum or pulley that constricts the osseofibrous tunnel through which the tendon runs.Sommario Le tenosinoviti sono infiammazioni delle guaine sinoviali dei tendini. Le tenosinoviti stenosanti sono delle entità particolari, condizionate da molteplici fattori. Si tratta di patologie favorite dall'anatomia locale, da fattori meccanici ed ormonali. Le principali tenosinoviti stenosanti sono: la tendinopatia di de Quervain, la tenosinovite stenosante dei tendini flessori delle dita o dito a scatto, la tenosinovite stenosante del tendine estensore ulnare del carpo, dei tendini estensori radiali del carpo e degli estensori comuni, la tenosinovite stenosante del tendine flessore dell'alluce, la tenosinovite stenosante dei tendini peronei. La loro diagnosi si basa sull'ecografia, che mostra un segno cardine: l'ispessimento del retinacolo o della puleggia rispetto al tendine ed il suo carattere stenosante. ª

“…Studies measuring forces during colonoscopy have demonstrated high peak forces, especially during colonoscope insertion, which may reach levels associated with an increased risk of injury to the thumb and wrist. [33][34][35][36] A quantitative analysis of these risk factors and the potential for upper extremity biomechanical overload was recently conducted by using the Occupational Repetitive Actions (OCRA) index in 6 Italian endoscopists. 37 The OCRA index is an ergonomic riskassessment tool that considers all repetitive tasks in a work cycle and stratifies the risk of injury into 3 levels: green (no risk), yellow (low risk), and red (risk).…”

“…Cognitive evaluation techniques have been successfully applied to medical devices (Martin et al 2008) but these need to be complemented with suitable techniques for assessment of physical interaction. It is possible to integrate video recordings of tasks with EMG data collection to extract sub task specific force data, as for example in the study of colonoscopes by Shergill et al (2009b). However, they did not collect posture data simultaneously.…”

“…As the participants were surrogates they had, as such, no previous skills or techniques in performing the procedure so their pace is assumed to be unrepresentative of that of a physician. Shergill et al (2009b) made HAL ratings of 4 for colonscopy work in a theater and this rating will be assumed to be indicative of the pace of such work in a clinical setting.…”

The purpose of this study was to develop and test a physical ergonomics assessment approach for medical device handles. The method assesses wrist posture and force of exertion simultaneously by task element. Electrogoniometers and EMG sensors were connected through a data acquisition module for synchronization with video recordings of trials. Task analysis of video recordings was performed offline with Observer XT software. Average posture and force data across several repetitions of individual task elements were calculated and presented in a format suitable for informing product designers of specific issues during a test trial. A handle comfort questionnaire is proposed to survey subjective responses. The evaluation approach was applied to an endoscope needle in sampling a biopsy from the stomach wall using a gastrointestinal track simulator with ten physician surrogates. The results showed that for all task elements the wrist was in extension (33 0 -45 0 ). Peak muscle forces ranged from 28% to 68% MVC across the three muscles studied. Muscle peak forces were above ACGIH HAL maximum threshold limits for four of the seven task elements, and above the action limit for all seven task elements for two muscles. The handle comfort questionnaire data also supported the high muscle force findings, and also on force distribution on the handle due to contact stresses. This combined approach could be used to collect and report detailed early stage ergonomics data from user trials on patient care simulators. The approach is proposed for use by medical device designers at the design stage of new products using prototypes, but it could also be used on existing products with real patients.3
