Force transfer / gripping conditions
Optimum: easy to grip - good gripping design Restricted: greater holding forces required - no shaped grips Considerably hindered: hardly possible to grip (slippery, soft, hard edges) - no or only unsuitable grips
Hand/arm position
Good: rare deviations - no continuous static arm posture Restricted: occasionally joints at the limit of movement ranges - occasional long continuous static arm posture Unfavorable: frequently joints at the limit of movement ranges - frequent long continuous static arm posture Poor: constantly joints at the limit of movement ranges - constant long continuous static arm posture
Unfavorable working conditions
Good: reliable recognition of detail - no dazzle - good climatic conditions Restricted: occasionally impaired detail recognition - difficult conditions such as draught, cold, disturbed concentration (noise) Unfavorable: frequently impaired detail recognition - frequently difficult conditions such as draught, cold, disturbed concentration (noise)
Body posture / movement
Work organization
Good: frequent variation of the physical workload with other activities Restricted: rare variation of the physical workload with other activities Unfavorable: no/hardly any variation of the physical workload with other activities

Risk score:

< 20 points	Physical overload is unlikely No measures necessary
20 - 50 points	Physical overload is possible for less resilient persons Measures may be helpful
50 - 100 points	Physical overload is also possible for normally resilient persons Measures needed
> 100 points	Physical overload is likely Measures necessary

Limitations of this calculator:
Interpolating and weighted averages of multiple forces and multiple postures is not possible with the calculator. Fill in the KIM form manually if you want to interpolate and use weighted averages.
