Chronic Plantar Fasciitis

corticosteroid injection, infracalcaneal peppering injection, Plantar Fasciitis
Brief summary
Although no single treatment has shown superiority, short-term pain relief may be offered via a targeted local corticosteroid injection (CSI), used often in combination with local anesthetic (LA), which may reduce plantar fasciitis symptoms for up to 1 month. Moreover, administering a CSI is relatively quick and easy for any Provider to perform, though it is not without potential deleterious side effects and risks, including fibroblast degradation, fat pad atrophy, skin depigmentation, and even plantar fascia rupture.
Detailed description
Research performed in other musculoskeletal disorders (e.g. lateral epicondylitis) suggest that the method (i.e peppering vs single bolus deposition) of injection is more favorable than the steroid itself, though evidence for this positive effect in plantar fasciitis is rather scarce. Injection via peppering is a minimally invasive percutaneous technique which involves repeatedly fenestrating the pathologic site (i.e. plantar fascia) via hypodermic needle insertion at the tender area, then sequentially injecting a substance, withdrawing, redirecting, and reinserting all without emerging from the skin. Though hypothetical, this technique is thought to disrupt the degenerative process of Plantar Fasciitis (PF), encouraging both localized bleeding and fibroblastic proliferation and stimulating a local inflammatory response that would trigger the body's own reparative mechanism, leading to recovery.

Study design
Masking description
A nurse or staff member will open a previously prepared and sealed opaque envelope (prepared beforehand by the clinical coordinator) labeled with the participant identification (ID) of the patient, which will be unique to the individual and different from their Medical Record Number (MRN). In this envelope, they will discover the patient's assigned treatment arm. The nurse or staff member will then prepare the syringe with the assigned treatment arm. Once the syringe is filled with the designated substance, the syringe will be wrapped with opaque tape or dark Coban wrap to conceal the contents in the syringe for both the PI and study participant.
Intervention model description
All patients ages 18 years and up with a diagnosis of plantar heel pain will be screened for inclusion into the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale Score - General Heel Tenderness | Baseline | A sheet of paper with a printed VAS scale will be given to the patient. The patient will be instructed to make a bold dot on the line based on how they rate their general heel pain, using the parameters listed on the scale (0 meaning no pain, 20 meaning mild pain, 50 meaning moderate pain, 80 meaning extreme pain, and 100 meaning the worst pain imaginable). Range 0-100. |
| Visual Analog Scale Score - First Step Pain | Baseline | A sheet of paper with a printed visual analog scale will be given to the patient. The patient will be instructed to make a bold dot on the line based on how they rate their first step heel pain, using the parameters listed on the scale (0 meaning no pain, 20 meaning mild pain, 50 meaning moderate pain, 80 meaning extreme pain, and 100 meaning the worst pain imaginable). Range = 0-100. |
| Foot Function Index (FFI) Score | Baseline | Questionnaire that measures pain, activity limitation, and disability in the foot. The FFI consists of 23 items grouped into three subscales: (1) Pain (9 items); (2) Disability (9 items); and (3) Activity Limitation (5 items). Each item is rated on a scale from 0-9 for the Pain and Disability subscales and 0-5 for the Activity Limitation subscale. For each subscale, scores are summed, divided by the maximum possible total for applicable items (excluding any marked not applicable), and multiplied by 100 to yield a percentage score from 0 to 100. Lower FFI scores indicate better foot function, while higher FFI scores reflect greater impairment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Heel Pressure Threshold Score - Asymptomatic Foot | Baseline, Week 2, Week 4, Week 8, Week 12 | Using a dolorimeter each participant's heel pressure threshold will be assessed. Level of pain on a 35-point scale will be noted with 0 meaning no pain and 35 meaning extreme pain. |
| Exit Survey Score | Week 12 | Upon completion of study related procedures and assessments, participants will be given a paper exit survey to complete. 5 questions asked relating to their experience in the study and if they would recommend the study to others. Total score range 1-10 with 1 being worst experience and 10 being best experience. |
| Heel Tenderness Score - Asymptomatic Foot | Baseline, week 2, week 4, week 8, week 12 | The physician will assess heel pain on palpation. Heel tenderness index will be used which has a range of 0-3 points (0 points = no pain, 1 point = painful, 2 points = painful and winces, 3 points = painful, winces, and withdraws). |
| Heel Tenderness Score - Symptomatic Foot | Baseline, Week 2, Week 4, Week 8, and Week 12 | The physician will assess heel pain on palpation. Heel tenderness index will be used which has a range of 0-3 points (0 points = no pain, 1 point = painful, 2 points = painful and winces, 3 points = painful, winces, and withdraws). |
| Number of Completed Exercises | Week 2, Week 4, Week 8, and Week 12 | Participants will document in a daily exercise diary if any of the three recommended exercises (calf stretching, plantar fascia specific stretching, and loading exercise) were completed. Participants will also be asked to document why exercises were not completed if applicable. |
| Heel Pressure Threshold Score - Symptomatic Foot | Baseline, Week 2, Week 4, Week 8, and Week 12 | Using a dolorimeter each participant's heel pressure threshold will be assessed. Level of pain on a 35-point scale will be noted with 0 meaning no pain and 35 meaning extreme pain. |

Heel Tenderness Score - Asymptomatic Foot
The physician will assess heel pain on palpation. Heel tenderness index will be used which has a range of 0-3 points (0 points = no pain, 1 point = painful, 2 points = painful and winces, 3 points = painful, winces, and withdraws).
Time frame: Baseline, week 2, week 4, week 8, week 12
Population: Baseline: CSI/LA 2 missing data; LA/saline 2 missing data. WK 2: CSI/LA 2 missed appt, 2 did not complete study; LA/saline 1 did not complete study, 3 missed appt, 2 missing data.
