Brief Summary:
A clinical trial evaluating the effectiveness, safety and patient tolerance for the use of Intense Therapeutic Ultrasound (ITU) for chronic, Plantar Fasciitis musculoskeletal tissue pain reduction began in August 2016 and was completed in April 2017. The clinical setting: University Foot and Ankle Institute, Santa Monica, California, USA; Single-Blinded, pivotal study for chronic plantar fasciitis.

Condition or disease Intervention/treatment Phase
Plantar Fasciitis, Chronic Device: Intense Therapeutic Ultrasound Treatment Not Applicable

Detailed Description:
Intense Therapeutic Ultrasound (ITU) is an established ultrasound based therapy in which sound waves are concentrated and focused into selected musculoskeletal tissue, to produce selective thermal coagulative changes over a small controlled area while leaving the surrounding tissue unaffected. These coagulative changes are known to begin the body's tissue response cascade and promote collagen generation in the targeted anatomy resulting in pain reduction.

Arm Intervention/treatment
Experimental: Intense Therapeutic Ultrasound Treatment
Intense Therapeutic Ultrasound treatment applied along the length and width of the proximal Plantar Fascia. 1000 - 5 Joule pulses were applied twice, four weeks apart.
Device: Intense Therapeutic Ultrasound Treatment
Other Names:
  • Guided Therapy Systems, Ardent Sound, GTS, ITU
  • Actisound

Primary Outcome Measures :
  1. Patient Reported Pain Via the Universal Visual Analog Scale: Pass Criteria = at Least 25% Pain Reduction [ Time Frame: At 12 weeks after the first treatment ]
    Patient Reported Pain Reduction meeting or exceeding 25% using the Universal Visual Analog Scale. The Universal Visual Analog Scale is a 10 Point pain scale, where 0 = No Pain, 1 = slight Pain and 10 = the patient's worst imaginable pain. Ratings of 2 to 9 describe pain increases of 10%/Rating. For this measure a reduction of 25% on the Universal Visual Analog Scale is considered meeting the Pain Reduction Criteria. Lower Scale numbers compared to reported baseline ratings equates to pain reduction.

Secondary Outcome Measures :
  1. Ultrasound Changes [ Time Frame: At 12 Weeks after the first treatment ]
    Diagnostic Ultrasound Changes: Hypoechoic Lesion Volume Reduction following 2 Intense Therapeutic Ultrasound Treatments

  2. Percentage of Change of Pain and Hypoechoic Lesion Volume Compared to Baseline [ Time Frame: At 12 Weeks after the first treatment ]
    Compare percentage of Mean changes in pain via the Patient Reported Universal Visual Analog Scale compared to Mean Patient Reported Baseline Pain Scores and percentage of Mean change of Plantar Fascia Hypoechoic Lesion Volume compared to mean baseline Hypoechoic lesion volume following two Intense Therapeutic Ultrasound Treatments, using Diagnostic Ultrasound Images. For Plantar Fascia Hypoechoic Lesion Volume, each lesion volume was calculated using: (4/3) π x R1 x R2 x R3, where r = Radius of each measurement: Lesion Length(1), width(2) and depth(3)
