·        Program Evaluation of the maximum handling load:   evaluation of the acceptability of a work condition as a function of:

1.    The weight of the load

2.    The frequency of handling per minute

3.    The maximum load allowed at this frequency

4.    The distance to which the load is carried

5.    The duration per day (in minutes)

    Estimate of

1.    The total weight per minute

2.    The maximum total weight per min 

3.    The total weight per hour

4.    The maximum total weight per hour 

5.    The total weight per day

6.    The maximum total weight per day 

    Judgment of the acceptability of the work situation


·        Program NIOSH: calculation of the index of lifting according to NIOSH method


·        Program STRAIN INDEX:

This index was proposed by Moore, J. S., Garg, A., "The Strain Index: A Proposed Method to Analyze Jobs for Risk of Distal Upper Extremity Disorders,"  Am. Ind. Hyg. Assoc. J. 56 (5): 443-458, 1995

The index is evaluated from estimates of

·        The force necessary to complete the tasks   

·        The duration of the efforts (in % of the cycle time)

·        The number of efforts per minute

·        The postures adopted by the wrists/hands

·        the work speed

·        The work duration per day

From this index and on the basis of data presented by the authors, I propose the estimate of the predicted average Prevalence (#TMS/100 workers/years)


My opinion: I find this index relatively easy to calculate and thus interesting if a quantification is really necessary.
