ASTRO XO™ Clinical Study
Ten plantar fasciitis patients walked 20-30 minutes per day using the device for 12 weeks.
Conducted by the Scholl School of Podiatry at Rosalind Franklin University, North Chicago, IL in conjunction with Weil Foot and Ankle Research Institute, Des Plaines, Illinois.
Statistical Data Highlights
The results indicate significant improvements across several key areas effecting pain and pressure on the foot and ankle while walking.
71%* reduction in first step morning pain on the Visual Analog Scale in plantar fasciitis patients, demonstrating significant overall pain relief.
Improved Ankle Dorsiflexion
38%* increase in ankle dorsiflexion during the Lunge Test showing greater ankle joint ROM.
Reduced Heel Contact Time
39%* reduction in heel contact time showing that the foot moves more effectively from heel strike to mid-stance because of increased forward propulsive gait.
Improved Peak Pressure Time Integral
41%* reduction in peak pressure time integral, demonstrating more uniform timing of gait from heel strike to midstance thru toe-off.
Increased Tibialis Anterior Activity
95% increase in tibialis anterior active time, suggesting heightened TA muscle activity which contributes to greater ankle dorsiflexion and moment during stance phase.
Increased Gastrocnemius Activity
74% increase in gastrocnemius active time, suggesting increased GS muscle activity contributing to forward propulsive gait from midstance through toe off.

ASTRO XO™ Clinical Indications
The ASTRO XO™ clinical trial directly defined its efficacy for treatment of plantar fasciitis. Data collected as part of the trial also defined the ASTRO XO™ mechanism of action. These data support application of the product in a range of indications where restoration of ankle power and forward propulsion are thought to offer clinical benefit to the patient. Application of the device in all cases is at the discretion of the clinician.
|Plantar Fasciitis||The ASTRO XO™ clinical study with PF patients showed a 71% pain reduction while restoring ankle power and forward propulsion during ambulation.|
|Achilles Tendinitis & Insertional Pain||The ASTRO XO™ clinical study produced biomechanical data important to resolving AT including improved GS & TA activation, 38% ankle DF improvement resulting in meaningful forward propulsion improvements.|
|Ankle Sprain & Chronic Ankle Instability (CAI)||The ASTRO XO™ clinical study produced biomechanical data important to rehabilitating ankle proprioception and ROM resulting from ankle sprain & CAI.|
|Posterior Tibial Tendon Dysfunction (PTTD)||The ASTRO XO™ clinical study showed the device generated meaningful improvements in GS activation which provides basis for its use in rehabilitating Stage I & II PTTD.|
|Gait Rehabilitation for Knee OA & TKA||The ASTRO XO™ clinical study showed the device promotes rehabilitation of ankle power and forward propulsion which is a need of patients for knee osteoarthritis and total knee arthroplasty surgery (TKA).|
|Gait Rehabilitation after Immobilization||The ASTRO XO™ clinical study showed the device promotes rehabilitation of ankle power and forward propulsion which is a gait improvement need in patients completing cam boot use after injury or surgery.|
ASTRO XO™ Contraindications
A patient should not use ASTRO XO™ if he/she has any of the following diseases or conditions that may be exacerbated by use of the ASTRO XO™ device.
- Diabetic peripheral neuropathy or other diabetic foot complications.
- Poor circulation in the lower extremities (ex. Peripheral Artery Disease, etc.)
- Cardiovascular conditions that would prevent the patient from safely walking up to two miles per day wearing the ASTRO XO™ device.
- Orthopedic and other conditions in the leg, knee, foot, ankle and hip that could be adversely affected by the ASTRO XO™ device.
- Lower leg muscles and tendons that are torn or at risk of rupture.
- Stroke rehabilitation conditions like drop foot, where added plantar flexion would be detrimental to walking gait and balance.
- Inadequate balance and gait control such that ASTRO XO™ use would significantly increase the risk of a serious fall or other injury.
- Any other condition where use of the ASTRO XO™ would be detrimental to the patient.
