CLINICAL SUPPORT

Study 1: Heel OffLoading

Using a pressure-sensing mat, 19 patients in a long-term care facility were tested for heel pressure on a mattress, in a heelmedix device, and in the competitor’s device. Heelmedix completely offload the vulnerable heel area. Here are the pressure mapping conclusions:

Study 2: Plantar Flexion

Prolonged plantar flexion (a toe-down motion of foot at the ankle) can contribute to foot drop. Foot drop is a condition of uncontrolled plantar flexion that can develop in non-ambulatory patients.

Results and Conclusions*

  • Heelmedix demonstrated a 24.5% greater resistance to plantar flexion and twice the supportive strength of the competitor.
  • The strapping design on Heelmedix was able to prevent a foot drop beyond 40 degrees under all force conditions, while heel offloading on the competitor’s boot was not able to stop this severe foot drop angle.

MAXIMUM PRESSURE EXERTED PER ANGLE

The strapping design on Heelmedix was able to prevent a foot drop beyond 40 degrees under all force conditions.

Study 3: Strap Durability

Straps on a heel protector are important for ensuring that the boot stays properly fitted for each individual patient. If straps have the capability of stretching out there is a potential that the boot will not remain secure on the patient.

Results and Conclusions*

  • Heelmedix straps were relatively unchanged following repetitive strap pulls compared with the competitor’s straps, which increased 89.53% in length.
  • When tested under tension to failure, Heelmedix straps were three times stronger than the competitor’s.

TENSILE STRENGTH AT BREAK

Heelmedix straps required over three times more force to break than the competitor’s straps.
