About this trial

The goal of this clinical study is to develop a specialized rehabilitation exercise protocol designed for patients diagnosed with foot pathologies and calf muscle shortening, regardless of their choice to undergo minimally invasive ultrasound-guided surgery. The primary focus is to assess disparities in outcomes, particularly in the recovery of ankle mobility degrees. Additionally, for patients opting for minimally invasive ultrasound-guided surgery, the study aims to evaluate the resumption of both sporting activities and daily routines using the aforementioned specific rehabilitation protocol.

The primary questions this study aims to answer are:

* How does the proposed rehabilitation protocol impact ankle mobility recovery for patients with foot pathologies and calf muscle shortening? * What are the differences observed in the return to sporting activities and daily life among patients undergoing minimally invasive ultrasound-guided surgery, following the prescribed protocol?

Participants enrolled in this study will be engaged in:

Undertaking the specified rehabilitation exercises tailored for foot pathologies and calf muscle shortening.

Those opting for minimally invasive ultrasound-guided surgery will follow the same rehabilitation protocol post-surgery to assess its impact on their return to normal activities.

If there exists a comparison group:

Researchers will compare participants who undergo minimally invasive ultrasound-guided surgery against those who choose other treatment options to discern any differential effects on ankle mobility recovery and resumption of activities.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with shortened posterior musculature.

Chronic ankle pain.

Limitations in activities of daily living.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Specific protocol of rehabilitation exercise

    Procedure/Surgery

    Specific protocol of rehabilitation exercise

  • Short gastrocnemius surgery.

    Procedure/Surgery

    During surgery, a partial release of the gastrocnemius muscle tendon is performed to relieve tension and allow greater range of motion. This procedure is typically performed on an outpatient basis and under local or regional anesthesia, which allows for a quicker recovery compared to more invasive surgeries.

Treatment groups

Trial outcomes

Primary outcomes

1

Gait Analysis

The Gait Analysis is an examination useful for studying patterns, aided by instruments that measure the load on each limb and overall ambulation. The gait cycle ia s particularly complex phenomenon, resulting from the coordination between the nervous system, musculoskeletal system, and sensory input. The patient is required to walk (at varying intervals) on a treadmill or directly on a platform. It's a non invasive examination.

Time frame
Pre-surgery, 2 months, 6 months.
2

Baropodometric examination

The baropodometric examination, a pivotal tool in studying plantar pressure distribution, is conducted on the Zebris platform. This platform provides a detailed and precise analysis of pressures exerted on the plantar surface during walking, enabling a comprehensive assessment of alterations in load distribution on the feet. Zebris' technology allows for gathering relevant data on pressure points and load areas, facilitating the identification of abnormal gait patterns and postural imbalances. Integrated within the Zebris platform, this examination becomes an invaluable resource for comprehensive biomechanical assessment and personalized treatment planning for various foot pathologies.

Time frame
Pre-surgery, 2 months, 6 months.

Secondary outcomes

1

Passive ankle mobility

It is a tool that measures muscle strength and is used to evaluate the Passive ankle mobility test. The latter allows us to evaluate the equine.Measurement in degrees.

Time frame
Pre-surgery, 2 months, 6 months.
2

Short Form Health Survey 36 score

It's a self administered questionnaire filled out by the patient, aimed at quantifying health status and measuring health related quality of life. On this 0 - 100 scale of the The Short Form-36 Health Survey(SF-36), the higher the score obtained, the better the health status. Thus, 0 represents the worst state of health and 100 the best state of health as measured by the SF-36.

Time frame
Pre-surgery, 2 months, 6 months.
3

Foot Function Index

It is a questionnaire consisting of 23 items designed to assess the impact that foot pathologies have on the patient's perceived health status in terms of pain, disability and activity limitation.

Time frame
Pre-surgery, 2 months, 6 months.
4

American Orthopedic Foot and Ankle Score

The AOFAS Ankle-Hindfoot Scale was designed by the American Foot and Ankle Society to provide an international method to assess the clinical status of the ankle and foot. This questionnaire incorporates subjective and objective factors that are scored using a numerical scale and describe variables of function, alignment and pain. The score ranges from 0 to 100 depending on the degree of limitation of the patient.

Time frame
Pre-surgery, 2 months, 6 months.

Other outcomes

1

Olerud and Molander ankle score.

it is a functional assessment scale that uses a numerical scoring approach to measure a patient's function or status in relation to nine different items. In this case, the variable measured through this scale is a continuous quantitative variable. the scale assigns scores ranging from 0 to 100, based on the patient's responses or evaluations regarding the nine mentioned items. Higher scores indicate better functioning or a more favorable health status, while lower scores indicate impaired functioning or a less favorable health state.

Time frame
Pre-surgery, 2 months, 6 months.
2

Visual Analogue Scale

A 10-centimeter horizontal line is used, with extreme expressions of a symptom at both ends; absence or lesser intensity on the left and greater intensity on the right. The patient marks the point indicating intensity, measures it with a millimeter ruler, and expresses it in centimeters. The classification is: Mild pain (less than 3), moderate pain (between 4 and 7), and severe pain (8 or higher).

Time frame
Pre-surgery, 2 months, 6 months.
