Wang, CJ et al. "Long-term results of extracorporeal shockwave treatment for plantar fasciitis." Am J Sports Med (2006) Apr;34(4):592-6.
Study Type: RCT with non-placebo control group with conservative treatment
Results: Mean F/U interval: OssaTron 64 months; Control 40 months. 69.1% excellent, 13.6% good, 6.2% fair, and 11.1% poor for ESWT group. 0% excellent, 55% good, 36% fair, and 9% poor for the control group
The recurrence rate was 11% (9/81 heels) for the ESWT group versus 55% (43/78 heels) for the control group (P < .001).

Study Type: Prospective randomized clinical study with cross over
Results: At 12 weeks’ follow-up after high dose ESWT treatment, the treated group had 63% improvement. The second, non-treated group was unchanged after continuation of non-surgical treatment. The second group then received ESWT and both groups were followed to 2 years with 94% improvement in the first and 90% improvement in the second. Over this period of time, the first group had not deteriorated and the second group approached the first group’s results. Therefore, both groups had significant clinical improvement following high-dose ESWT. These improvements were maintained at 2 years of follow-up.

Study Type: One to Two Year Follow-up Study to a Blinded Prospective Controlled Study
Results: High Energy Success Rate 90.9%

Wilner, JM "Extracorporeal Shockwave Therapy for Plantar Fasciitis and Other Muscularskeletal Conditions Utilizing the OssaTron® - An Update." Clin Podiatr Med Surg, 21, 2004: 441-47.
Study Type: Retrospective
Results: After single treatment, 87% good to excellent success after 2 years from OssaTron® treatment.

Ogden, John, et al. "Electrohydraulic High-Energy Shock-Wave treatment for Chronic Plantar Fasciitis." The Journal of Bone and Joint Surgery, 2004, Vol86-A, No. 10, 2216-2228.
Study Type: Randomized, placebo controlled, multi-blinded, multi-center. One to Five Year follow-up study to a blinded randomized high energy controlled study
Results: High Energy sustained success, of non-randomized patients, at five years was 95% (n=20). High Energy sustained success at one year, of blinded patients with three month success was 97% (n= 67). High energy sustained success at one year of blinded patients who were retreated and had success at three months was 82% (n=22).
Data supports the use of high energy ESW treatment before consideration of any open or endoscopic surgical treatment.

HealthTronics: FDA Chronic Lateral Epicondylitis Final Report.
Study Type: Double Blind, Multi-Center, Randomized Controlled Study
Results: Treatment success evident by 8 weeks for patients with chronic lateral epicondylitis post treatment was maintained 100% of the randomized subjects treated with a single ESW treatment and followed to 12 months post treatment.

HealthTronics: FDA Chronic Plantar Fasciitis Final Report.
Study Type: Double Blind, Multi-Center, Randomized Controlled Study
Results: Treatment success evident by 8 weeks for patients with chronic plantar fasciitis post treatment was maintained 96% of the randomized subjects treated with a single ESW treatment and followed to 12 months post treatment.
