lymphodema machines

hello ladies,

I was watching This Morning the other day and there was a lady on there having a makeover who stated she has lymphodema and has a ‘machine’ which she uses at home to manage it,does anyone know what these machines are and if they are any good

I didn’t watch the programme, could she be referring to bioimpedance machines? Our local hospital uses them, they measure electrical current through your arm before lymphodema becomes symptomatic.
