About this study
Official title: EQUISOCK: New Antiequine for Ankle
The goal of this experimental study is to test the feasibility and validity of a new orthosis in patients with ankle lesions (external popliteal sciatic nerve or nerve injuries resulting in loss of ankle dorsiflexion) of both sexes and all ages. The main question it aims to answer is:Is the new orthosis a support for ankle stability??Does the new orthosis improve ankle function and patients' quality of life??The control group will be the subjects themselves when wearing their conventional ankle orthosis or without it. Participants must wear the new ankle orthosis for at least one month to assess the effectiveness of the orthosis and evaluate any changes that have occurred in the ankle joint and muscles.
- Being tested
- EQUISOCK, Other ankle orthosis
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EQUISOCKDevice
Participants must wear the new ankle orthosis during assessments and in their daily lives for at least one month, which is the duration of the study.
Other ankle orthosisDevice
Participants must wear the conventional ankle orthosis and without orthosis, during assessments and before wearing the new one
| Study group | Role | What they receive |
|---|---|---|
| EQUISOCK group | Experimental | Participants must wear the new ankle orthosis during assessments and in their daily lives for at least one month, which is the duration of the study. Receives: Device: EQUISOCK |
| Other ankle orthosis | Active comparator | Participants must wear the conventional ankle orthosis (and without orthosis) during assessments and in their daily lives, before wear the new one. Receives: Device: Other ankle orthosis |
What is being measured
The primary outcome is the main question the study is designed to answer.
Device Feasibility
Device feasibility will be assessed through participants' awareness of the device, as an indicator of its accessibility, visibility, and potential for effective implementation within the target population. A self diary Will be requested
Measured: Baseline and up to 4 weeks
Secondary outcomes (3)
Ankle function with virtual reality
Ankle function will be assessed using a virtual reality programme that requires movement of the lower limb to assess ankle stability, with and without orthosis. The assessment will be using a Borg scale (range of effort that the individual perceives when exercising). From 0 points (minimum effort) to 10 points (maximum effort).
Measured: Baseline and up to 4 weeks
Range of motion with Gyko device
The range of motion of the knee joint will be measured using the Gyko device with and without the new orthosis. The assessment will be in degrees (from 0 to 120º)
Measured: Baseline and up to 4 weeks
Footprint with a pressure platform
The distribution of static and dynamic load will be assessed with and without orthosis, using a pressure platform, as well as static balance with eyes open and closed and dynamic balance. The assessment will be the percentage of support from the sole of the foot in each movement.
Measured: Baseline and up to 4 weeks
