Electrical Stimulation for Shoulder Pain

EFFECTIVENESS: 2/5

As discussed above, the effectiveness of electrical stimulation is somewhat up for debate. Used as part of an integrated program which includes active care (exercise), the effectiveness of electrical stimulation is arguably improved. Used as an isolated therapy there is still little evidence of effectiveness. [i], [ii], [iii]

SELF CARE: 4/5

While electrical stimulation is often provided by medical providers, most of these therapies are available for home use, and can be bought by the general public. However, caution should be noted before using any form of electrical stimulation due to the potential associated risks, and the fact that a proper diagnosis from a licensed provider is always recommended to be sure the therapy is indicated in the first place.

COST: 5/5

Digital TENS units for example are available online for as little as $30-$150+. Compared to the costs of traditional medical care (injections, physical therapy, medications), these units would be considered very affordable.

USEFULNESS: 3/5

There are many forms of “electrical stimulation”. Examples include: TENS, Interferential and muscle stimulation. These therapies are somewhat controversial due to the lack of evidence about their effectiveness.[i] While they don’t work for everyone, they can be very useful for those who do benefit. The key: these therapies should rarely if ever be used in isolation, but often can be beneficial as part of a well-rounded program that includes active therapy (exercise).
