About this study

The aims of this study are to: (1) determine muscle activation of the tibialis posterior muscle during different common gastrocnemius stretches and (2) radiographically quantify the tibial-calcaneal angle during the common stretching positions. We hypothesize that stretching over the edge of a step with the arch supported will minimize the activation of the tibialis posterior muscle in addition to increasing the tibial-calcaneal angle.

Read the detailed description

Many studies have assessed the effect of dynamic and passive support of the medial longitudinal arch. The posterior tibial tendon is the main dynamic stabilizer of the medial longitudinal arch, although peroneus/fibularis longus, flexor digitorum longus, and flexor hallucis longus also contribute to a lesser degree. Passive structures also a play role in supporting the arch and include the plantar fascia, plantar ligaments and spring ligament. These plantar structures aid in preventing collapse of the arch during weight bearing.

Several studies have demonstrated that increased tension from the triceps surae can lead to flattening of the arch. Gastrocnemius muscle tightness in particular is thought to be partially responsible for many forefoot and midfoot conditions in non-neurologically impaired patients. Therefore, identifying effective ways to stretch the gastrocnemius muscle without creating increased stress through dynamic structures that support the longitudinal arch may be important for the management of individuals with limited gastrocnemius flexibility.

Common ways to stretch the gastrocnemius include a runner's stretch, stretching with the foot fully supported on a ramp, stretching with the arch of the foot supported on the edge of step and the heel dropping down toward the ground and lastly, stretching with the ball of the foot supported on the edge of a step and the heel dropping down toward the ground. To our knowledge no other studies have assessed the muscle activation of the tibialis posterior muscle via indwelling EMG activation in addition to radiographic measurements to determine the effectiveness of common gastrocnemius stretches. Therefore, the aims of this study are to determine muscle activation of the tibialis posterior muscle during different common gastrocnemius stretches and to radiographically quantify the tibial-calcaneal angle. We hypothesize that stretching over the edge of a step with the arch supported will minimize the activation of the tibialis posterior muscle in addition to increasing the tibial-calcaneal angle more than the other stretching positions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. EMG activation

    EMG activation of tibialis posterior muscle during 4 common gastrocnemius stretching positions

    Measured: up to 6 months

  2. Radiographic evaluation

    radiographically the angle of the tibia-calcaneus axis and calcaneal pitch between four different common gastrocnemius stretches

    Measured: up to 6 months

Secondary outcomes (1)
  1. Relationship between foot posture and radiographic evaluation of tibia-calcaneal angle

    Assess if there is a relationship between radiographic stretching position and foot posture

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Gastrocnemius Tightness, run by Regis University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

EMG activation (time frame: up to 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05015088, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Oct 2023.
