Jing, Xiaolu, Fulmer, Scott, Dasgupta, Priya Darshini, Yuan, Lu and Buchholz, Bryan (2010): Quantitative Ergonomics Exposure Assessment for Floor Coverers in the Greater Boston Area. In: Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting 2010. pp. 1219-1223.

“Floor Coverers have a high prevalence of knee related injuries. The objective of this study is to quantify whole body ergonomics exposure for Floor Coverers in the greater Boston area. A total of 6213 observations (about 100 hours) were made on 49 Floor Coverers by 7 trained observers in 8 construction sites. Awkward leg postures were common. "Kneeling/Crawling" was observed 61.2% of the time. Nonneutral trunk postures were observed frequently. "Severe”

Jing, Xiaolu, Fulmer, Scott and Buchholz, Bryan (2009): Posture, Activities, Tools, and Handling Analysis for Floor Coverers Focusing on the Knee. In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 1277-1281.

“Floor Coverers suffer high rates of knee-related musculoskeletal disorders. The purpose of this study was to determine which tasks have high priority for intervention. A total of 5126 discrete data observations were collected using the PATH method on 24 professional Floor Coverers. With respect to leg posture for each task and the combination of leg posture and MMH, fitting and installing vinyl composite tile (VCT) and fitting and installing baseboard had the highest exposures. Fitting and installing wood floor and fitting and installing carpet had medium exposures.”

Buchholz, Bryan and Wellman, Helen (1995): Practical Application of a Biaxial Goniometer to the Wrist Joint. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 558-562.

“The objectives of this study were: 1) to determine errors in wrist angle measurements from a commercially-available biaxial electrogoniometer and 2) to develop a calibration routine in order to correct for these errors. Goniometric measurements were simultaneously collected with true angular data using a fixture that allowed wrist movement in one plane while restricting motion in the orthogonal plane. These data were collected in two sets of trials: 1) flexion/extension with radial/ulnar deviation restricted and 2) radial/ulnar deviation with flexion/extension restricted. During these trials, discrete 30 degree increments of forearm rotation were studied. The results showed the expected cross talk and zero drift errors during forearm rotation. The application of mathematical equations that describe the effect of goniometer twist during forearm rotation resulted in significant error reduction for most trials. The calibration technique employs both a slope and a displacement transformation to improve the accuracy of angular data. The calibration technique may be used on data collected in the field if forearm rotation is measured simultaneously with the goniometer data.”

Perez-Balke, Graciela and Buchholz, Bryan (1995): A Study of the Effect of a Wrist Splint on Extrinsic Flexor and Anterior Deltoid Electromyography during a Pick-and-Place Task. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 958.

“Wrist splints have recently gained popularity as a control for work stressors associated with musculoskeletal disorders such as carpal tunnel syndrome. Awkward postures, force, and repetition have been identified as work stressors. The goal of this study was to determine the effect of the use of a rigid wrist splint on force, via surface electromyography (EMG) during a repetitive pick and place task. Extrinsic flexor EMG (EF) and anterior deltoid EMG (AD) increased 37.4% (+/- 21.8) and 12.5% (+/- 18.5), respectively, with the use of the splint (p< 0.01). In addition, peak power grip strength (PGS),”

Fisher, Donald L., Andres, Robert O., Buchholz, Bryan, Hughes, Richard and Marras, William S. (1992): Applications of Optimization in Biomechanics: Consensus and Controversy. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 722-723.

“Increasingly, optimization is appearing as an integral part of biomechanical solutions to ergonomic problems. The primary objective of this panel is to introduce several different optimization tools and point out their related strengths and weaknesses. Optimization techniques have been used to solve a wide range of ergonomic problems. These problems include those which prove the most costly of the occupationally related disorders (in particular, lower back disorders) and those which are the most frequently reported of the occupationally related disorders (in particular, repetitive motion disorders). The problems addressed by this panel will include the above two disorders as well as several related ones. Specifically, mention will made of both lower back disorders (Marras) and repetitive motion disorders (Fisher) as well as slips and falls (Andres), mechanical trauma to the upper extremities (Buchholz), and more general problems requiring the determination of muscle forces (Hughes). The applications were also chosen to provide a window on the controversy which is attached to the use of various optimization techniques. Three elements of the controversy will be discussed: the verifiability of the ideal or optimal models of the biomechanical system; the tractability of the optimization techniques; and the generality of the optimization techniques.”
