Is Electric Shock Wave Therapy (ESWT) better than InterX (NIN) in the treatment of Plantar Fasciitis ?

February 18, 2024

The short answer is No!

Electric Shockwave Therapy (ESWT) is not better than InterX (NIN) in the treatment of Plantar Fasciitis

InterX Treatment was effective in more than 90% of cases on reducing pain and improving functional mobility, while reducing the intake of pain and anti-inflammatory medication. The full published journal is available here https://www.jfas.org/article/S1067-2516(17)30158-8/fulltext

Conclusion from the published journal below

In conclusion, NIN using the InterX 5002 was shown to be an effective treatment of chronic plantar fasciitis resistant to treatment, with full patient satisfaction in >90% of cases. The present prospective randomized controlled study showed superior results with NIN (InterX) compared with ESWT( Electric Shock Wave Therapy), in terms of the functional score, pain improvement ,and daily intake of NSAIDs.

Shock Wave therapy was also effective in helping plantar fasciitis, but patients described more pain during and post treatment. The overall result of the study was significantly better for InterX Treatment. Another important thing to note was that age and gender did not affect results and in only 5% of cases weight proved a issue. On all the areas measured InterX Reduced pain and helped mobility.

The results of the study are similar to my own of 90% success in treating plantar fasciitis. The difference is I use a bespoke movement rehabilitation programme to aid in faster recovery. The InterX works at a cellular level to aid in the healing of the fascia, and is a neuro stimulator to help release natural pain and anti-inflammatory endorphins.

The combination of the InterX Treatment and movement programme have been shown to be highly successful in treating plantar fasciitis.
