Advice on which ultrasound device to purchase for my condition?

good day, on and off for the past 10 years i have suffered from rotator cuff impingement. ive been to physio and they have helped me many times to rehab shoulder with excercises and ultrasound. Im thinking of of purchasing a personal home unit yet im not sure which frequency unit i should buy. 1, 3 or 5 mhz. if i purchase a 1mhz unit is this to strong of a frequency and will it cause more harm. or should i get a 3 or 5 mhz unit. im looking at something like the unit listed here:

US-1000 1Mhz Portable Home Ultrasound Therapy Machine

the unit says it has 3 settings low med, and high.

Any advice would be appreciated. Thank you

Burning the periosteome is a danger when doing it on your own. Also how will you do it on your self or do you have someone to help

the unit has a low med, and high setting. I would be doing it on myself on a low setting, time : 4min on injured area

It is just difficult to treat the superspinatus tendon, for instance, with the other arm. let alone the infaspinatus tendon. You would most like rly cause impingement and rotator cuff irrational on good shoulder by treating the bad.

What's a low setting to you? Each setting is defined by depth of tissue need to be treated, each tendon (4 in rotator cuff) lies in diffrent depths to the skin. So settings should be changed depending on tendon treated.

Also there is the anatomical locations of the most efficient areas to place ultrasound head to reduce bone heating and induce thermal effects to tendon.

Thirdly, 4 mins won't make any clinical change in tissues because the temp of tendon and surrounding wont reach desired 39-40 degrees.

I think this idea might be a false economy but if your going to do it best to go on course or pay the wife to go on it.
