There's some MATLAB code written to perform Woltring's algorithm
which is a generic spline/low-pass filter. Among other things, we've
used it to do EMG processing (However, the EMG's were already
rectified). Try the ISB site

I have a sample m file which use Woltring's to filter and bin a sample
EMG file. http://isb.ri.ccf.org/software/gcvspl/reina/woltring_filter.m
Maybe you can add on to it to get the rectification and integration
(easy with MATLAB).

Hope that helps.
