validity of the baltimore Therapeutic Equipment work simulator in the measurement of lifting endurance in healthy men
American Journal of Occupational Therapy, 2001Co-Authors: W Ting, Sharon Brintnell, Jean Wessel, Rammohan V Maikala, Yagesh BhambhaniAbstract:OBJECTIVE: To examine the criterion validity of the Baltimore Therapeutic Equipment (BTE) work simulator by comparing endurance time, oxygen uptake (VO2), and heart rate measured during real and simulated lifting tasks and to derive a regression equation for predicting actual lifting endurance from measurements on the work simulator. METHOD: Twenty healthy male volunteers repetitively lifted and lowered a load of 40 lb using the BTE work simulator and actual weights at a laboratory workstation. Postures, location, and frequency of lifts were kept constant. Endurance (defined as the time taken for the rating of perceived exertion to increase 2 units on the Borg scale) was measured under both conditions. VO2 and heart rate were also recorded, using standard physiological procedures. RESULTS: The mean values for endurance time, steady-state VO2, and heart rate were significantly different between the real and simulated tasks (p < .05). Correlation of endurance time between the two tasks was significant (r = .71, p < .05). Step wise regression analysis resulted in the following equation for predicting real endurance from simulated time measurements: predicted real time = .34 simulated time + 3.29; r = .71; SE = 1.00 min. CONCLUSION: The BTE work simulator tends to overestimate real lifting endurance performance in healthy men. The lower physiological stress during the simulated task suggests a significant difference between the real and simulated loads. Occupational therapists should exercise caution when using the results of the BTE work simulator during functional capacity evaluations.

Gender Differences in Work Performance on the Baltimore Therapeutic Equipment Work Simulator
The American journal of occupational therapy : official publication of the American Occupational Therapy Association, 1995Co-Authors: Shaniff Esmail, Yagesh Bhambhani, Sharon BrintnellAbstract:OBJECTIVES The purposes of this study were to (a) establish biomechanical and physiological normative data for healthy young women performing three tasks on the Baltimore Therapeutic Equipment work simulator (BTE): wheel-turn, push-pull, and overhead-reach; and (b) compare these data with previously reported values for healthy men of a similar age group. METHOD Twenty women completed five test sessions: (a) task familiarization on the BTE to determine the work intensity that was perceived as hard on the Borg scale, (b) incremental test on an arm crank ergometer to measure peak oxygen uptake (VO2) and peak heart rate (HR), and (c) one of the three tasks in random order for 4 min during the next three sessions. Physiological responses were monitored with a metabolic cart interfaced with an electrocardiogram. RESULTS Torque, work, and power during the three tasks were significantly higher (p .05) gender differences were observed. Computation of energy expenditure relative to body weight and power output (cal.kg-1.W-1) indicated that women expended significantly (p .05) gender differences were observed for VO2 and HR when the values were expressed as a percentage of their respective peaks. CONCLUSIONS Findings indicated that (a) the functional work capacity is significantly lower in women than in men, (b) women are less efficient than men when the energy expenditure is expressed per unit of body weight and power output, and (c) the relative physiological stress in men and women is similar under these conditions.

the baltimore Therapeutic Equipment work simulator biomechanical and physiological norms for three attachments in healthy men
American Journal of Occupational Therapy, 1994Co-Authors: Yagesh Bhambhani, Shaniff Esmail, Sharon BrintnellAbstract:OBJECTIVES: The Baltimore Therapeutic Equipment (BTE) work simulator is routinely used by occupational therapists in functional capacity evaluation. Currently, there is a lack of normative data for various attachments on this instrument. The purposes of this study were to (a) establish norms for the biomechanical and physiological responses during three tasks on the BTE work simulator, namely, wheel-turn, push-pull, and overhead-reach; (b) compare these responses during the three tasks, and (c) examine the interrelationships of these responses during the tasks. METHOD: Twenty healthy men completed five testing sessions: (a) task familiarization on the BTE work simulator to identify the work intensity, which was perceived as hard on the Borg scale; (b) an incremental arm ergometer exercise test to determine their peak oxygen uptake (pVO2) and peak heart rate (pHR); and (c) one of the three tasks on the BTE work simulator for 4 min in each of the next three sessions. RESULTS: Analysis of variance indicated that torque, work, and power during the overhead-reach were significantly higher (p = .000) compared with the wheel-turn and push-pull tasks. However, no significant differences (p > .05) were observed among the tasks for the VO2 and HR, which were approximately 50% and 70% of pVO2 and pHR respectively. Although there was a significant relationship (p < .05) among tasks for the torque, work, and power, the common variance ranged only between 38% and 67%. The relative pVO2 was significantly related to work (p = .028) and power (p = .027) only during the push-pull task but not the wheel-turn and overhead-reach tasks. CONCLUSIONS: These results suggest that occupational therapists should include as many tasks as possible when designing functional capacity evaluation test batteries, and that there is no consistent relationship between cardiorespiratory fitness and performance of various tasks on the BTE work simulator.

the baltimore Therapeutic Equipment work simulator reliability and validity at three work intensities
Archives of Physical Medicine and Rehabilitation, 1991Co-Authors: Lorian E Kennedy, Yagesh BhambhaniAbstract:Abstract To determine test-retest reliability and criterion validity of the Baltimore Therapeutic Equipment Work Simulator (BTE), 30 male volunteers, 18 to 30 years, performed three criterion tasks at light (CL), medium (CM), and heavy (CH) levels of intensity and three corresponding simulated tasks (SL, SM, SH), all of which were repeated on a subsequent session. Oxygen consumption (VO 2 ) and heart rate (HR) were monitored continuously during these tasks. Correlation coefficients between trials of the same task for VO 2 ( r = .74–.87) and HR ( r = .58–.78) indicated significant test-retest reliability. Although criterion-simulation correlation coefficients were significant, consistently high criterion validity was found only at CL-SL (VO 2 , r = .81 and .83; HR, r = .88 and .95). The nature of the task may have influenced CM-SM correlations. It also appears that subjects underestimated the amount of resistance required on the BTE to simulate CH. Caution is urged in making judgments about a subject's abilities to do real work at medium and heavy intensities based only on test results from the BTE.

Baltimore Therapeutic Equipment work simulator : energy expenditure of work activities in cardiac patients
Archives of physical medicine and rehabilitation, 1993Co-Authors: Nancy A. Wilke, Lois M. Sheldahl, Sara M. Dougherty, Scot G. Levandoski, Felix E. TristaniAbstract:The energy expenditure and hemodynamic responses to tasks performed on the Baltimore Therapeutic Equipment (BTE) work simulator were evaluated in men with coronary artery disease and compared to tasks performed at a laboratory workstation in which actual tools and Equipment were used. Met units for the BTE work simulator and corresponding workstation tasks, respectively, were drill press operation, 1.5 +/- 0.1 and 1.5 +/- 0.3Mets; hammering, 2.3 +/- 0.3 and 3.4 +/- 0.8Mets (p < 0.05); repetitive lifting a 22.7kg weight load, 3.8 +/- 0.6 and 4.5 +/- 0.9Mets (p < 0.05); mechanic work in a supine position, 2.0 +/- 0.5 and 1.7 +/- 0.2Mets; sanding wood, 2.0 +/- 0.3 and 2.5 +/- 0.7Mets; sawing wood, 3.2 +/- 0.6 and 4.3 +/- 0.7Mets (p < 0.05); screwdriving, 2.2 +/- 0.3 and 2.5 +/- 0.5Mets (p < 0.05); shoveling, 5.45kg load 4.6 +/- 1.0 and 4.2 +/- 0.7Mets; sweeping, 1.7 +/- 0.2 and 3.0 +/- 0.4Mets (p < 0.05); and vacuuming, 2.7 +/- 0.7 and 2.9 +/- 0.5Mets. The results indicate that there is a tendency for the metabolic and hemodynamic responses to BTE work simulator tasks to be lower than that of the actual activity.
