#1
Minseok Son, Jaemoon Jung, Woojin Park
Evaluating physical discomfort of designed gestures is important for creating safe and usable gesture-based interaction systems; yet, gestural discomfort evaluation has not been extensively studied in HCI, and few evaluation methods seem currently available whose utility has been experimentally confirmed. To address this, this study empirically demonstrated the utility of the subjective rating method after a small number of gesture repetitions (a maximum of four repetitions) in evaluating designed gestures in terms of physical discomfort resulting from prolonged, repetitive gesture use...

This case study used the Nordic Musculoskeletal Questionnaire (NMQ) to explore work that involves handling gas cylinders and to determine risk factors that may cause related injuries. The NMQ survey was distributed to 100 gas cylinder handlers in Taiwan, and their handling tasks were analyzed. The results showed that the overall prevalence of musculoskeletal disorders was 91% within 1 year. More than half of the respondents (62%) experienced shoulder discomfort, followed by lower back/waist (57%) and neck (47%) discomfort...

Work related musculoskeletal disorders (WMSD) are a serious risk to workers' health in any work environment, and especially in clinical work places. These disorders are typically the result of prolonged exposure to non-ergonomic postures and the resulting discomfort in the workplace. Thus a continuous assessment of comfort and ergonomics is necessary. There are different techniques available to make such assessments, such as self-reports on perceived discomfort and observational scoring models based on the posture's relevant joint angles...

STUDY DESIGN: Case series (longitudinal). INTRODUCTION: Only few reports concerning the efficacy of commonly used strategies for preventing upper limb occupational disorders associated with prolonged typing exist. PURPOSE OF THE STUDY: We aimed to investigate whether the duration of typing and the use of 2 strategies (hand rest and wrist support) changes muscle physiological response and therefore the electromyography records. METHODS: We enrolled 25 volunteers, who were unfamiliar with the task and did not have musculoskeletal disorders...

Movement variability of the upper limb was investigated using a bimanual Fitts' task. Participants tapped rhythmically between target-pairs of different Index of Difficulties (ID) for three intervals of 20 min each. We studied the effects of ID and time-on-task on movement time, end-point variability, approximate entropy and standard deviation of relative phase. Lower ID and time-on-task caused decreasing movement time and increasing end-point variability. Moreover, standard deviation of relative phase and approximate entropy moderately increased...

Propelling a manual wheelchair (MWC) is a strenuous task that causes upper limb musculoskeletal disorders (MSD) in a large proportion of MWC users. Although most studies on MWC propulsion biomechanics assume that MWC propulsion is a relatively symmetric task, recent literature suggests that this is the case only when the assessed outcome measures are averaged over long periods of time, and not over short periods (i.e., instantaneously). No method is currently available to assess instantaneous symmetry. In this work, we present the Instantaneous Symmetry Index (ISI), a new method that quantifies how a variable has been instantaneously asymmetric during a selected time period...

Lifting and holding upper and lower limbs during the "prep and drape" portion of certain orthopaedic procedures exert strong forces on the holder and may lead to musculoskeletal disorders. To address these challenges during upper extremity procedures, this article describes a hand-free elevation and traction technique of the upper limbs during preoperative skin preparation with the use of items readily available within the operating room (OR). This technique is particularly useful for heavy or fractured limbs that may impose a physical challenge to lift and maintain in a stable position...

We identified factors protective of all-cause sickness absence (SA) among subjects with multisite musculoskeletal pain (MSP). The nationally representative source sample comprised 3420 actively working Finns aged 30-55 in year 2000 and alive at follow-up. Pain in 18 body locations was combined into four sites (neck, low back, upper limbs, lower limbs). The baseline prevalence of MSP (pain in ≥ 2 sites) was 32 %. Baseline data on sociodemographic factors, work ability, work, health, and lifestyle were gathered by questionnaire, interview and clinical examination and linked with national registers on all-cause SA (periods lasting ≥10 workdays) for 2002-2008...
