Brief Summary:
Range of motion at ankle joint and subtalar joint will be assessed before and after utilization of ARM device. The changes in range of motion will be recorded and compared to literature.

Condition or disease Intervention/treatment Phase
Plantar Fasciitis Flatfoot Calcaneus Fractures Device: Non-Measuring Ankle Exerciser Not Applicable

Detailed Description:

The purpose of this study is to assess how effective a new device is in increasing range of motion and reducing stiffness in the foot and ankle of patients with acquired flatfoot, patients with plantar fasciitis, and those suffering from stiffness after cast removal or other lengthy immobilization.

Project will utilize a physical therapist to measure range of motion and stiffness when patients are consented. Patients will be re-measured at six weeks following use of the device to assist in stretching ankle and foot muscles, and again at 10 weeks for final stiffness and range of motion assessment.

Arm Intervention/treatment
No Intervention: Standard of care
Patient ankle range of motion will be assessed at clinic visit. No stretching exercises with the device, but will be provided standard care through physiotherapist in acute cases, and no stretching exercises for chronic patients. Reassessment will be done at six weeks and 10 weeks.
Experimental: Non-Measuring Ankle Exerciser
Subjects will train using only one combination of movement, dorsiflexion with inversion. This is done by manipulating the ring so that the medial and anterior ropes are taut. Subject will start with 3 minute warm-up. Subject will then manipulate the ring so that the foot moves into dorsiflexion with inversion until a point of tolerable discomfort is felt; subject will hold this position for 30 seconds. Stretch will be repeated 10 times, each day, for six weeks. Reassessment will be done at six weeks and 10 weeks.
Device: Non-Measuring Ankle Exerciser
Stretching exercise performed 10 times per day, for six (6) weeks.
Other Name: Ankle Recovery Mechanism (ARM)

Primary Outcome Measures :
  1. Change in Range of Motion [ Time Frame: Ten weeks ]
    Participants randomized into ARM stretching device group will experience less ankle stiffness and an increased range of motion after using the stretching device, as compared to the control group receiving traditional physiotherapy.
