Is there a home device to measure my PLMD?

During a recent sleep study, I was diagnosed with Periodic Leg Movement Disorder (PLMD). This disorder has been very detrimental to my sleep.

I have been dealing with this by reducing my daily dose of Lexapro from 20mg to 10mg and taking 600mg of Gabapentin.

Does anyone know if there is a home device to measure my leg movements during the night? It would be helpful if I had some measure of the impact of my Sleep Apnea, Lexapro and Gabapentin.

Thank you very much.
