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.

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.

Interventions

Recruitment details

26 participants were enrolled. While we know the number who completed the study (23), we do not know to which group/arm they were assigned. There are no other recruitment details, study results or data available as the PI left the institution without making this information available to the research department.

ArmCount
Standard of Care or Ankle Exerciser
Patient ankle range of motion will be assessed at clinic visit. They will either receive standard care physiotherapy, or use the ankle exerciser in the following manner: 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.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.
