SECTION 3.  PROJECT NARRATIVE 
 
1) Background 
 The primary objective of this study is to evaluate the efficacy of combining intense therapeutic ultrasound (ITU) 
with standard care for the treatment of chronic plantar fasciitis.  A secondary objective is to evaluate the tolerability 
and safety of intense therapeutic ultrasound in the treatment of plantar fasciitis. 
These objectives will be accomplished through the following specific aims: 
Aim # 1: Compare patient reported outcomes of pain, function and level of activity for subjects treated with 
standard of care plus ITU (ITU group) to those treated with standard of care plus sham ITU (control group).    
Aim # 2: Compare the changes in plantar fascia thickness in subjects treated with standard of care plus ITU to those 
treated with standard of care plus sham ITU.     
Aim # 3: Evaluate the tolerability and safety of ITU for the treatment of chronic plantar fasciitisChronic Plantar 
Fasciitis.  Chronic plantar fasciitis (CPF) is a common cause of plantar heel pain that is a result of a degenerative 
process of the plantar fascia and its surrounding perifascial structures.  It is the most common cause of heel pain, 
affecting 10% of the U.S. population, and one of the most common foot and ankle problems. One study showed that 
individuals with this disease scored significantly lower in general health-related quality of life in addition to foot 
specific quality of life (pain and function). 
The plantar fascia, or plantar aponeurosis, originates on the posterior tuberosity of the calcaneus and inserts into the 
proximal phalanges of the toes. It acts like a cable, which tightens with flexion of the metatarsophalangeal joints, 
the “windlass” mechanism, thereby restoring the arch during mid-stance, stiffening the medial column of foot for 
push-off and transferring the force of the gastrocnemius muscle contracture to the ground. Although the exact 
etiology of CPF is unclear, the predominance of evidence indicates that it is the combination of age and overuse 
which lead to degenerative changes within the fascia that result in the symptoms associated with this disease.  The 
most common presentation for patients with plantar fasciitis include pain with the first few steps in the morning, 
pain at the beginning of the activity that resolves with continued activity, pain and stiffness with prolonged 
standing, and pain at the end of the day. 
The diagnosis of CPF is made clinically based on history and physical exam.  Confirmation with diagnostic 
imaging may be necessary when the symptoms are atypical or are refractory to treatment.  MRI is a useful 
diagnostic tool to evaluate for plantar fascia thickening and edema in and around the fascia, both of which are 
consistent with the diagnosis of CPF. In addition, many physicians use MRI to exclude other causes of plantar heel 
pain. Ultrasound can also be used to measure the thickness of the plantar fascia. Multiple studies have shown that 
patients with CPF have increased thickness of the fascia compared to asymptomatic individuals. Mean thickness in 
these studies for subjects with CPF range from 4.8-6.5 mm as opposed to 2.3-4.0 mm for subjects without the 
disease. One of the studies showed that the thickness was increased in medial, central and lateral bands of plantar

fascia uniformly along with 68% of patients with CPF reporting central band tenderness as opposed to 26% having 
lateral band tenderness. In addition to the evidence of inflammation, the presence of a hyper-echoic lesion in the 
plantar fascia was noted in 68% to 84% of patients with CPF. Diagnostic ultrasound has also been used to quantify 
the effectiveness of treatments such as extra-corporeal shock wave therapy, NSAIDs and Botox injections for 
subjects with CPF. 
More than twenty different treatments have been used for plantar fasciitis. The combination of rest, ice, stretching 
and NSAIDs are used as initial management in most patients and have been shown to effectively treat symptoms in 
90% of patients in less than 12 months. However, 10% of patients fail conservative management and continue to 
have symptoms beyond 12 months (termed refractory plantar fasciitis or RPF). Surgery consisting of partial plantar 
fascia release or gastrocnemius recession is often considered in these patients.  However, the outcomes of surgery 
are not uniformly positive with 50% of patients reporting residual symptoms.  Moreover, evidence supporting 
surgical treatment of RPF is weak as there are no randomized controlled trials comparing its efficacy to other 
treatments.  Thus, for many patients the risks of surgery such as arch instability, prolonged wound healing, and 
longer rehabilitation times simply outweigh the benefits.  Is there a non-invasive treatment that can be used as an 
adjunct to speed healing in patients with CPF and as an alternative to surgery in those with RPF?  The primary 
objective of this study is to evaluate the efficacy of combining the non-invasive treatment with intense therapeutic 
ultrasound (ITU) with standard care for the treatment of chronic plantar fasciitis.  A secondary objective is to 
evaluate the tolerability and safety of intense therapeutic ultrasound in the treatment of plantar fasciitis.   
Intense therapeutic ultrasound (ITU). Various types of ultrasound have been used to treat soft tissue injuries since 
the 1930s. Intense therapeutic ultrasound (ITU) is a recently developed ultrasound based therapy in which sound 
waves are concentrated to produce selective thermal coagulative change over a small area while leaving the 
remaining regions unaffected.  ITU has been used clinically for treating the facial skin for the past decade and it has 
recently received FDA approvals for non-surgical brow and submental tissue lifting. Over 300,000 patients 
worldwide have been treated using this technology. Clinical studies have shown that 85% of subjects receiving this 
treatment on facial skin tissue showed an improvement in facial lifting with no significant pain, erythema, 
inflammation or scarring. Histologically, it has been shown that ITU induces the production of dermal collagen 
with thickening of the dermis and straightening of the elastic fibers in the reticular dermis. On-going research in our 
laboratory has shown that ITU can improve healing of damaged Achilles tendon in a rabbit model.  Preliminary 
results showed an increase in markers for wound healing (e.g. VEGFa, TNFα, IL-1β, and TGFβ1) and a decrease in 
markers for scar tissue formation (e.g. COL1α1, COL1α2, and COL2α2) in injured rabbit tendon treated with ITU 
compared to injured, untreated rabbit tendon.  These results have led us to want to explore the possibility using ITU 
to treat patients with CPF.  
 
2) Lay Summary (approximately 400 words) 
 The purpose of this study is to assess the effectiveness of ITU in the treatment of CPF by comparing pain, 
function, and change in plantar fascia thickness in subjects treated with ITU in addition to standard of care to 
subjects that are treated with standard of care alone. The primary outcome measure will be a computer adaptive 
questionnaire where pain, function and level of activity will be compared between the two groups. In addition, 
with the use of diagnostic ultrasound, plantar fascia thickness and presence or absence of hyper-echoic lesion 
will be compared between the two groups.  Finally, the safety and tolerability of ITU will be monitored through 
the course of the study.  It is hypothesized that patients receiving ITU in addition to standard of care will have a 
more rapid resolution of their pain, faster return to activities, and a greater decrease in plantar fascia thickening 
on ultrasound as compared to those only receiving standard of care.

3) Setting of the Human Research 
The PI is an assistant professor in the Department of Orthopaedic Surgery and surgeon with the University of 
Arizona Health Network.  Subjects will be recruited from the outpatient clinic of Drs. Daniel Latt (PI) and Peg 
Chilvers.  The age, gender, height, weight, activity level, pain level, and physical exam findings of patients will 
be obtained directly from the subject, the subject’s medical record, or from direct examination and then 
recorded in a password protected excel file.  The online survey can be completed from any computer available 
to the subject.  Intense therapeutic ultrasound and diagnostic ultrasound will be administered in the Human 
Movements Biomechanics Lab (BRL B101).  
 
4) Resources available to conduct the Human Research  
Equipment for intense therapeutic ultrasound will be provided by Michael Slayton and Rich Amodei from 
Guided Therapy Systems.  The equipment for measuring height and weight will be in the orthopedic clinic.  
Personnel available to conduct the study include 2 surgeons, 1 clinical research coordinator, 2 sonographers, 1 
medical student, and 2 undergraduate assistants.  These individuals will be available to recruit and consent 
patients, coordinate and conduct the study, analyze the data, and produce a manuscript. 
5) Study Population 
Male and female adults (18 years or older) with plantar heel pain and point tenderness near the medial calcaneal 
insertion of the plantar fascia for at least three months without improvement will be considered for inclusion 
into the study.  Subjects with diabetes, bilateral plantar heel pain, current systemic or local infection, previous 
foot surgeries, other foot/ankle pathologies (inflammatory arthritis, gout, neurologic disorders, connective 
tissue disorders and malignancy), contraindications to the use of NSAIDs, and pregnancy will be excluded.  
The target enrollment of this pilot study is 50 participants.    
 
6) Recruitment Methods and Consenting Process 
Subjects will be recruited utilizing public media, list serves, community organizations, and via referral.  Please 
see the attachments to this application for an electronic media and brochure representations of the 
advertisements to be utilized.   We would like to select from the following wording to produce recruitment 
materials - 
“We are seeking adults with chronic heel pain.   Have you had chronic heel pain?  Chronic heel pain is pain 
which has been present for at least 3 months and may be the result of plantar fasciitis.  Have you had heel pain 
for the last 3 months?  It may be the result of plantar fasciitis.  Plantar Fasciitis is a painful, inflammatory 
condition occurring where the plantar fascia attaches to the calcaneus (heel bone).    The most common 
symptoms are 1) pain with the first few steps in the morning, 2) pain at the beginning of an activity which 
improves as the plantar fascia is stretched during the activity, 3) pain and stiffness with prolonged standing, 
and 4) pain at the end of the day.  The standard treatment of Chronic Plantar Fasciitis consists of stretching, 
anti-inflammatory medications (NSAIDS), and heel cups.  Despite these treatments, 5% - 20% of patients will 
still have symptoms at 1 year!  Participate in a study to determine the effectiveness of Intense Therapeutic 
Ultrasound for the treatment of Chronic Plantar Fasciitis.  What is Intense Therapeutic Ultrasound?  Intense 
Therapeutic Ultrasound (ITU) is a noninvasive method of healing tissues with sound waves.  ITU promotes 
collagen generation and is FDA approved for the non-surgical lifting of the brow.  What is the purpose of this 
study?  The purpose of this study is to determine if intense ultrasound can promote healing of plantar fasciitis.  
This study will determine the effectiveness of ITU in speeding the healing of plantar fasciitis.  The time required

to heal will be compared for traditional treatment methods + placebo to that required by traditional treatment 
+ ITU.  Every subject will receive anti-inflammatory medication, a viscoelastic heel cup, and physical therapy.  
Patients receiving just these treatments will be compared to those also receiving ITU treatments.  Who can 
participate?  The following criteria are required for participation:  A physician associated with the study has 
diagnosed you with plantar fasciitis.  To be eligible you need to have chronic heel pain that is diagnosed as 
plantar fasciitis by a physician associated with the study.   The/your symptoms exist in only one foot.    You 
must not have diabetes or be pregnant.  You must be 18 years or older.  What will participation require?  You 
will need to be assigned to either a control group (standard medical care) or to an experimental group 
(standard medical care + ITU).  You will need to not use any other treatments. You will need to commit to the 
assigned treatment for 3 months.  You will need to answer an additional online or telephone questionnaire at 6 
months.  Why should I participate?  Although you will not receive payment, what is learned may benefit others!  
To participate, please call [contact information].  If interested, please call [contact information]or send an 
email to [contact information] and provide preferred contact information.” 
 
In addition to anatomical labeling of the achilles tendon, calcaneus, and plantar fascia, we would like to use 
the captions, “Inflammation of the plantar fascia can cause heel pain” and “stretching the plantar fascia.”     
Interested individuals who contact the laboratory will have the logistics of the study explained and be referred 
to the clinic for diagnosis and treatment of heel pain.  All patients diagnosed with plantar fasciitis by 
participating physicians will be contacted by the research team to to discuss the details associated with 
participation.  We would like to obtain a temporary deferment of authorization to obtain contact information 
from the electronic medical record for those individuals who are initially identified in the clinics by 
participating physicians.  Additionally, we would like permission to provide the consent and authorization 
forms and other information by e/mail should this be conducive to obtaining informed consent.  The mailing is 
for informational purposes only to allow the subject more time to consider participation in the study.  The 
informed consent process will be completed in person.  Both English and Spanish versions of the consent forms 
will be utilized, although the Spanish consent form will be submitted as a modification once the English version 
is approved. Finally, we would like to provide a map and information sheet to assist participation in the study 
(see attachments). 
  
7) Procedures involved in the Human Research 
After obtaining informed consent and authorization from the subject, study personnel will verify the 
screening of participants utilizing the inclusion/exclusion criteria and collect the following 
information- age, gender, height, weight, activity level, pain level, and physical exam findings 
including x-rays - which will be recorded on the data abstraction sheet (see attachment).  The 
activities strictly associated with the research are the assignment to a study group (Control or ITU), 
the administration of patient reported outcome measures (questionnaires), and therapeutic and/or 
diagnostic ultrasound (Table 1).  Additionally, adverse events will be recorded at each visit (see 
attachment).  Treatment tolerability will be prior to, immediately after, and at 2 days post-treatment.   
Standard of care is integrated into both arms of the investigation and includes a structured physical 
examination, the use of an NSAIDs for 3 weeks (Naprosyn 500 mg po bid or Ibuprofen 800 mg po tid 
taken with meals), viscoelastic heel cups for 12 weeks, and supervised physical therapy with home 
exercise program for 6 weeks. These components are described below-

Table 1. Calendar of Activities 
Structured physical examination.  The focused exam will consist of assessment of hindfoot and 
midfoot alignment, inspection for swelling, palpation of the calcaneus and entire plantar fascia, range 
of motion of the ankle with the knee flexed and with the knee extended, and calcaneal squeeze test. 
Pertinent positive findings on exam include: valgus hindfoot, midfoot planus, tenderness to palpation 
at the insertion of the plantar fascia onto the calcaneus, ankle dorsiflexion less than 10 degrees with 
the knee extended or greater than 10 degree augmentation in ankle dorsiflxion with the knee flexed. 
Pertinent negative findings include: lack of swelling at the ankle and midfoot, no tenderness at the 
Achilles insertion, the retrocalcaneal bursae, along the arch, posterior to the medial malleolus, or at 
Baxters point, and positive calcaneal squeeze test. 
Physical Therapy.   Supervised physical therapy will occur two times per week and include 
gastrocnemius stretching, plantar fascia specific stretching, modalities (ice and heat), and plantar 
fascia deep tissue massage (see instructions to PT appendix 2 of the protocol).  Use of advanced 
modalities such as iontophoresis, phonophoresis, or TENS will not be permitted. The home exercise 
program will consist of PF specific stretch and gastrocnemius stretch to be done for ten minutes two 
times per day (see home exercise program handout, Appendix 2 of the protocol).  Subjects will be 
required to record the frequency of each exercise in a logbook (see Appendix 3 of the protocol). 
The research components are described below- 
Randomization and Blinding.  Suitable subjects will be randomly assigned (1:1) to receive standard of 
care with a sham ultrasound treatment (Control group) or standard of care + ITU treatment (ITU 
group) by the application of an algorithm (e.g. even vs odd) to the number provided  by a random-
number generator.  Most members of the research team and the subject will be blinded to group 
assignment.  Only the clinical research coordinator and ultrasound treatment team will be privy to the 
subject’s group assignment. 
Patient Reported Outcome Measures (Aim 1).  The principal aim of this study is to compare the 
efficacy of treatment and time course of response to treatment between the two groups using validated

patient reported outcome measures assessing pain, function and level of activity. Subjects will 
complete validated patient reported outcome questionnaires assessing pain, function and level of 
activity prior to initiating treatment and at 0, 2, 4, 6, 12, and 24 weeks after starting treatment.   
 
Pain will be assessed using the of the foot function index pain subscale (FFI-P) and the subject 
reported outcome measures (SROM).  These two instruments have been used to assess pain in 
previous studies of plantar fascia treatments. (Please see Appendices 1-D and 1-E of the Protocol.) 
 
Function will be assessed using two validated PRO instruments the PROMIS PF CAT and the FAAM. 
The PROMIS PFCAT is a subject relevant outcome measure that uses computer adaptive survey 
questions to assess the patient’s pain and function in relation to daily activities.    (Please see 
Appendix 1-A of the Protocol.)  The FAAM has been shown to be a reliable, responsive, and valid 
measure of physical function for individuals with a broad range of musculoskeletal disorders of the 
lower leg, foot, and ankle.  (Please see Appendix 1-B of the Protocol.) 
 
Level of Activity will be assessed using the activity subscale of FAAM. This subscale scores 
quantitatively the level of difficulty subjects often face when they perform basic activities of daily 
living. It has shown to be an accurate and reliable predictor of the activity level while performing day-
to-day activities.  (Please see Appendix 1-B of the Protocol.) 
 
Diagnostic Ultrasound (Aim 2).  Diagnostic ultrasound will be utilized to compare the changes in 
plantar fascia thickness that occurs over time in subjects treated with standard care to those treated 
with ITU plus standard of care.  Diagnostic ultrasound imaging will be performed with an FDA 
approved ultrasound scanner (Spark® System, Ardent Sound, Inc. – Mesa, AZ, see Appendix 6 of 
proposal) using a coupling gel (Polysonic®, Parker Laboratories, Inc., Fairfield, NJ, see Appendix 7 
of the attached proposal) by a trained sonographer or physician. The subject will be positioned prone 
on an exam table with the feet over the edge of the table. The plantar fascia of the affected and 
contralateral feet will be imaged. The width and depth of the fascia as well as the size and location of 
a hyperechoic lesion, when present, will be recorded using both long and short axis imaging. Change 
in plantar fascia thickness relative to the baseline measurement will be calculated. Decreased 
thickness of 0.8 mm or greater will be considered clinically significant as these changes have been 
shown to correlate with decreased pain and increased mobility.

Experimental Treatment:  Intense Therapeutic Ultrasound (ITU).  Subjects in the ITU group will 
receive standard treatment plus two treatments (at week 0 and week 2) of ITU to the affected plantar 
fascia (Table 1 in red).  ITU treatment will be performed using a GEN II 
system (Guided Therapy Systems, Mesa, AZ). (Please see Appendix 5 of 
the Protocol.)  We are seeking classification as a non-significant risk 
(NSR) device.  (Please see the attached NSR statement.)  Trained study 
personnel will conduct the treatments.  The treatment session will last 15 
– 20 minutes. During this time the subjects will be required to lay prone 
position on an exam table with their feet hanging over the end of the 
table. An average energy up to 5 joules / thermal zone will be 
administered to the symptomatic Plantar Fascia in a linear pattern along 
the Plantar Fascia (Figure 1) with up to 50 lines. Each line will include 
individual thermal zones, less than 1 mm3 in volume, centered at 10 – 13 
mm depth, and approximately 2 mm apart.

around the insertion of the plantar  
fascia onto the posterior process

Assessment of Safety and Tolerability (Aim 3).  Subject self-assessments of treatment tolerability will 
be conducted immediately after, two days after (phone survey) and two weeks after treatment using 
a10-point visual analog scale (VAS, see Appendix 1-C).  The subject will be asked to report their 
current level of pain and the maximum level of pain experienced over the last two days. The VAS is 
the standard for assessing pain for both clinical and research purposes.  Recording of adverse events 
will take place at all visits (see adverse event reporting form Appendix 4 in the protocol). Adverse 
events and serious adverse events will be monitored throughout the study.  A treatment will not be 
administered if there is residual pain/discomfort experienced by the subject from the previous 
treatment.   
 
Statistical analysis.  Data will be assessed for variance homogeneity and normality.  FFI-P, PFCAT, 
and FAAM scores before and after intervention will be compared between the two groups using a 
paired t-test. Additionally, the mean thickness of the plantar fascia will be compared between the two 
groups before and after treatment and significance determined utilizing paired t tests.  P<0.05 is 
considered to be statistically significant. 
 
8) Risks to subjects 
Exposure to ITU may produce short-term sensations which may cause discomfort and mild erythema 
for up to a few hours following the exposure.  No detrimental side effects have been reported in 
previous clinical trials investigating similar devices in which ultrasound energy was applied to the 
neck and face.    Additionally, the ITU in this investigation will utilize lower power parameters than 
those reported for these similar devices.  We are seeking classification of the GEN II system (Guided

Therapy Systems, Mesa, AZ) as a non-significant risk device.  (Please see the attached NSR 
statement.)  Adverse events will be recorded at each visit (see appendix 4 of the protocol).       
Additionally, x-rays will be obtained as part of the standard care.  A small risk exists of developing 
cancer later in life as a result of exposure to radiation.        
Finally, risk of exposure of protected health information (PHI) exits.  However, we have minimized 
this risk by implementing three levels of precaution.  Access to protected health information will be 
restricted to the minimum number of individuals required to complete the tasks.  The files containing 
the PHI will be kept electronically and geographically separate from the data files with entries   
identified only by a randomly generated number to be used as the PHI key.  Both files will be 
encrypted and password protected and then stored on password protected, secured computers. 
9) Potential benefits to subjects and/or society 
 Subjects receiving intensive therapeutic ultrasound treatment may experience faster healing time, 
decreased pain and return to full function earlier as a result of the treatment. Patients not placed into 
the ITU group will receive no additional individual benefit by participating in the study. The results of 
this study may lead to further research or widespread clinical application of ITU in turn increasing 
knowledge in this area or improving the care available to individuals affected by plantar fasciitis.  
However, in general the subjects will obtain no significant benefit by participating in the study. 
 
10) 
Provisions to protect the privacy of subjects and the confidentiality of data 
The consenting process will be initiated in the clinic with the physicians in the privacy of an exam 
room.  The names and contact information for potential subjects will be kept in a password encrypted 
excel file on a password protected, secured computer.   Only the minimum number of research 
personnel required to complete the consenting process will have access to PHI.  Once enrolled in the 
study a unique patient identifier will be used in subsequent date files generated in the study.  . A list 
linking subjects to identifiable information will be stored on a password protected, secured computer. 
This list will only be accessible to the study coordinator during the study and to the PI (L Daniel Latt, 
MD PhD) following data analysis.  Should the arrival of subjects in the lab overlap, we will have a 
separate room available apart from the lab so that the consenting and subsequent exam and treatment 
can be conducted in privacy.  Should a participant decide to leave the study, the patient’s PHI records 
will be destroyed, but the data will be retained. Upon closure of the IRB project, all patient identifiers 
will be destroyed. 
 
11) 
Access to Private Information 
a. Authorization for access to Protected Health Information (PHI) 
We are requesting a temporary waiver of authorization so that we may obtain contact information 
from the medical records for those subjects identified in clinic as interested in the study.   We will 
obtain authorization for PHI during the consenting process.  This request is based upon the following 
justification-

1) The use or disclosure of protected health information involves no more than minimal risk to the privacy of 
individuals, based on , at least, the presence of the following elements; 
a) An adequate plan to protect the name and phone number from improper use and disclosure has been 
implemented through the utilization of password protected files.  Additionally, the PHI will be obtained and 
accessed only by the minimal number of investigators required to conduct the study.  Furthermore, the 
computer containing the PHI will be password protected and secured.   
b) An adequate plan to destroy the identifiers at the earliest opportunity consistent with conduct of the 
research, unless there is a health or research justification for retaining the identifiers or such retention is 
otherwise required by law, has been implemented in that the contact information will be destroyed if the 
subject declines participation.  An authorization will be obtained prior to the additional collection of PHI.   
c) Adequate written assurances that the protected health information will not be reused or disclosed to any 
other person or entity, except as required by law, for authorized oversight of the research study, or for other 
research for which the use or disclosure of protected health information would be permitted by HIPAA, are 
hereby provided in that the PHI will only be utilized to conduct the study as described within the attached 
protocol.       
2) The research could not practicably be conducted without the waiver or alteration of the HIPAA authorization 
requirement because access to contact information is required to begin the process of informed consent.  If the 
subject indicates that they are not interested in participating, their contact information will be removed from the 
encrypted data file.  No other information will be obtained from the records until authorization is provided by 
the subject.   
3) The research could not practicably be conducted without access to and use of the protected health information 
because obtaining authorization at the clinic for participation in the study may not be consistently feasible.   
  
12) 
Cost to subjects  
The proposed research has no associated costs to the subjects. 
 
13) 
Subject compensation 
The subjects will not be compensated. 
 
14) 
Medical care and compensation for injury  
  If an injury occurs, medical care is available.  No funds are available to cover compensation for any 
injury incurred as a result of participation in this investigation.    
15) 
Withdrawal of subjects 
Subjects may withdraw from the study at any time either in person, in writing, or by telephone. 
Subjects withdraw by contacting either Dr. Daniel Latt or the project lead.  Abrupt withdrawal
