The Usual Care + PBM Group
Participants that are assigned to this group will receive active treatment with PBM 3 times a week for 3 weeks for a total of 9 treatments. Photobiomodulation Therapy (PBMT): Participants will receive PBMT with the PBM device over the course of three consecutive weeks (three treatments per week). PBM treatments will take approximately 5-10 minutes to administer at each session. Specific treatment parameters will be based on measurements of calf, ankle, and foot using pre-calculated treatment tables; participants will receive 10 J/cm2, 25W output power, and the length of the treatment will be dependent on treatment area (size). PBMT will be administered by a trained member of the study team using the LightForce® XPi therapy laser, provided by LiteCure, LLC/DJO Global (New Castle, DE). The LightForce® XPi therapy laser is an FDA cleared device for the treatment of pain. The trained team members will use the Smart Hand Piece technology, which achieves effective treatments and improves dosing accuracy by assessing the operator's speed and providing real-time visual (red - amber - green light) and sensory feedback.
The Usual Care + Sham (Placebo) PBM Group
Participants that are assigned to this group will receive Sham PBM therapy 3 times a week for 3 weeks for a total of 9 treatments. Sham PBM therapy is an inactive harmless treatment that is intended to mimic the active PBM treatment. Sham-Photobiomodualtion Therapy (Sham-PBMT): Sham-PBM treatment time will be calculated in the same way as the PBM treatment group, with the time of treatment dependent on the size of the treatment area. The sham-PBMT will be administered by rolling the massage ball over the plantar surface of the foot and dorsal aspect of the calf in contact with the participants' skin. Because emission of photons at the selected treatment parameters may cause participants in the treatment group to feel warmth, the massage ball will be warmed in the sham-PBMT. The device will be turned on, so the red aiming beam will be visible, but the operator will not activate the switch to emit photons. At the completion of the initial 6 weeks, the Usual Care + Sham (Placebo) PBM Group will be unblinded, and may choose to cross-over and complete another 6 weeks in the active treatment group. If participants choose to cross-over and receive active PBMT, they will re-complete all of the original study procedures (with the exception of screening, as participants have qualified for the study, and baseline data collection, as the study team will use the 6-week follow-up data as the new baseline prior to active PBMT treatment.

PRIMARY outcome

Timeframe: Baseline

The FAAM is a 29-item self-report instrument that assesses physical function in foot and ankle impairments which included PF cases in development. There are two subscales, Activities of Daily Living(ADL) (21- item) and Sports (7-item). Each item is scored on a 5-point Likert scale (4='no difficulty at all' to 0='unable to do'); points are transformed to a percentage (100%=no dysfunction). The minimum clinically important difference 8 \& 9 points for ADL \& Sports subscale, respectively. Higher scores represent higher levels of function for each subscale, with 100% representing no dysfunction and 0% being dysfunction.

The Usual Care + PBM Group
n=33 Participants
Participants that were assigned to this group received treatment with PBM 3 times a week for 3 weeks for a total of 9 treatments. Photobiomodulation Therapy (PBMT): Participants received PBMT with the PBM device over the course of three consecutive weeks (three treatments per week). PBM treatments took approximately 5-10 minutes to administer at each session. Specific treatment parameters were based on measurements of calf, ankle, and foot using pre-calculated treatment tables; participants received 10 J/cm2, 25W output power, and the length of the treatment was dependent on treatment area (size). PBMT was administered by a trained member of the study team using the LightForce® XPi therapy laser, provided by LiteCure, LLC/DJO Global (New Castle, DE). The LightForce® XPi therapy laser is an FDA cleared device for the treatment of pain. The trained team members used the Smart Hand Piece technology, which achieves effective treatments and improves dosing accuracy by assessing the operator's speed and providing real-time visual (red - amber - green light) and sensory feedback.
The Usual Care + Sham (Placebo) PBM Group
n=26 Participants
Participants that were assigned to this group received Sham PBM therapy 3 times a week for 3 weeks for a total of 9 treatments. Sham PBM therapy was an inactive harmless treatment that was intended to mimic the active PBM treatment. Sham-Photobiomodualtion Therapy (Sham-PBMT): Sham-PBM treatment time will be calculated in the same way as the PBM treatment group, with the time of treatment dependent on the size of the treatment area. The sham-PBMT was administered by rolling the massage ball over the plantar surface of the foot and dorsal aspect of the calf in contact with the participants' skin. Because emission of photons at the selected treatment parameters may cause participants in the treatment group to feel warmth, the massage ball was warmed in the sham-PBMT. The device was turned on to make the red aiming beam visible, but the operator did not activate the switch to emit photons.

PRIMARY outcome

Timeframe: Baseline

Plantar fascia thickness was measured by an MSK US trained provider utilizing an ultrasound system. The patient was positioned prone on an examination table with the leg extending off the end so the foot projects downward in a relaxed state. Using a linear transducer for best resolution, the plantar fascia was evaluated in the long axis to determine the site to be measured as identified by the bony contour. The vertical thickness of the plantar fascia will be documented in both long and short axis at this point. The points measured were from the edge of the bone to the outer layer of the plantar fascia. The average of both long and short-axis measurements was analyzed for the PF thinness results.

The Usual Care + PBM Group
n=31 participants at risk
Participants that were assigned to this group received active treatment with PBM 3 times a week for 3 weeks for a total of 9 treatments. Photobiomodulation Therapy (PBMT): Participants received PBMT with the PBM device over the course of three consecutive weeks (three treatments per week). PBM treatments will take approximately 5-10 minutes to administer at each session. Specific treatment parameters were based on measurements of calf, ankle, and foot using pre-calculated treatment tables; participants received 10 J/cm2, 25W output power, and the length of the treatment was dependent on treatment area (size). PBMT was administered by a trained member of the study team using the LightForce® XPi therapy laser, provided by LiteCure, LLC/DJO Global (New Castle, DE). The LightForce® XPi therapy laser is an FDA cleared device for the treatment of pain. The trained team members will use the Smart Hand Piece technology, which achieves effective treatments and improves dosing accuracy by assessing the operator's speed and providing real-time visual (red - amber - green light) and sensory feedback.
The Usual Care + Sham (Placebo) PBM Group
n=33 participants at risk
Participants that were assigned to this group received Sham PBM therapy 3 times a week for 3 weeks for a total of 9 treatments. Sham PBM therapy is an inactive harmless treatment that is intended to mimic the active PBM treatment. Sham-Photobiomodualtion Therapy (Sham-PBMT): Sham-PBM treatment time was calculated in the same way as the PBM treatment group, with the time of treatment dependent on the size of the treatment area. The sham-PBMT was administered by rolling the massage ball over the plantar surface of the foot and dorsal aspect of the calf in contact with the participants' skin. Because emission of photons at the selected treatment parameters may cause participants in the treatment group to feel warmth, the massage was warmed in the sham-PBMT. The device was turned on, so the red aiming beam will be visible, but the operator did not activate the switch to emit photons.
The Usual Care + Sham (Placebo) PBM Group With Cross-over to Intervention
n=26 participants at risk
Participants that were decided to cross-over to this group received active treatment with PBM 3 times a week for 3 weeks for a total of 9 treatments. Photobiomodulation Therapy (PBMT): Participants received PBMT with the PBM device over the course of three consecutive weeks (three treatments per week). PBM treatments took approximately 5-10 minutes to administer at each session. Specific treatment parameters were based on measurements of calf, ankle, and foot using pre-calculated treatment tables; participants received 10 J/cm2, 25W output power, and the length of the treatment was dependent on treatment area (size).
