The Epley maneuver addresses BPPV, but there are other causes of vertigo, which a PT can determine.
PT's look for eye movements (nystagmus) after certain maneuvers, often using goggles and a screen.
I have been to PT for BPPV myself and with my mother and daughter. The last time I had it, I went online for maneuvers. I have neck issues so found one that was safe for me.
Sit on the edge of bed, looking straight ahead, for 30+ seconds. Turn head to right, and quickly drop on your side to the left, so that you are sort of facing the ceiling. Hold for 30 seconds or until dizziness subsides. Then sit upright and look straight ahead. Hold for 30+ seconds or until dizziness subsides. I do this three times a day.
Execrcises for other types of vertigo involve looking at an "x" on the wall and then turning head back and forth while staring at the "x." Using playing cards, hold one above eye level and one below eye level and look up and down between them. Then do horizontally and diagonally.
All of these exercises make the vertigo worse initially, for seconds or minutes at least, but in the end they work. BPPV is from crystals in the ear dislodging and the exercises help put them back apparently. The other vertigo exercises deal with inner ear and/or brain I was told.
After a serious car accident I ended up with vertigo. The Epley maneuver worked great. I was given sheet instructions, and did it at home. I have not had any more episodes since and hope not to have any more
