Backward Running on a Negative Slope as a Treatment for Achilles Tendinopathy in Runners
A study testing Backwards running on a Treadmil with a negative slope in people with Achilles Tendinopathy, run by Meuhedet. Healthcare Organization at 1 site in Israel.
Trial summary
This study will look to evaluate the feasibility of a backwards downhill running program as an option for the treatment of Achilles tendinopathy in runners. It is known that exercise on the Achilles tendon during elongation (eccentric exercise) improves tendon function after injury. Read more about this study

About this study
This study will look to evaluate the feasibility of a backwards downhill running program as an option for the treatment of Achilles tendinopathy in runners. It is known that exercise on the Achilles tendon during elongation (eccentric exercise) improves tendon function after injury. However, during recovery, the patient is required to stop tendon-loading activities such as jumps and sprints. Therefore, during recovery, athletes decline in physical fitness.
Backward running on a negative slope can achieve a biomechanical load similar to eccentric exercise without decreasing physical fitness.
Read the detailed description
The study was a prospective, single-arm feasibility study. Participants were patients who met the entry criteria and were referred to the Meuhedet health service Physical Therapy outpatient clinic, Jerusalem, from September 2019 to February 2020. The sample size was based on previous recommendations for pilot and feasibility studies (Julious 2005; Billingham, Whitehead, and Julious 2013). Inclusion criteria were: AT that was clinically determined by an orthopedic surgeon (E.S) according to nontraumatic pain and tenderness at the Achilles tendon and report of decreased activity levels secondary to Achilles pain; a history of running for at least one session a week in the past three months; age > 18 and < 70. Exclusion criteria were having other lower extremity injuries; prior treatment with eccentric exercise or currently receiving Physical Therapy for AT; received a steroid injection into the tendon in the three months prior, or underwent Achilles tendon surgery.
Participants received a total of nine treatment sessions, twice a week for a total of five weeks. Each treatment consisted of backward walking / running over an 8º negatively inclined treadmill. (Landice L7 Rehabilitation treadmill, New Jersey, USA) with a warmup and a cooldown on a stationary bike. A detailed description of the protocol is presented in Table 1. As backward locomotion on a treadmill was novel for all participants they were advised to hold the treadmill handles during the adjustment period (treatment sessions 1-3). Participants were also instructed to refrain from specific sports which involve continuous jumping and forward running throughout the intervention period. Patients were informed that if they do not feel comfortable with the training protocol, they could terminate their participation at any point.
Assessments took place at baseline, pretreatment four, pretreatment six, and at a separate meeting after treatment nine

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study will look to evaluate the feasibility of a backwards downhill running program as an option for the treatment of Achilles tendinopathy in runners. It is known that exercise on the Achilles tendon during elongation (eccentric exercise) improves tendon function after injury. However, during recovery, the patient is required to stop tendon-loading activities such as jumps and sprints. Therefore, during recovery, athletes decline in physical fitness.
Backward running on a negative slope can achieve a biomechanical load similar to eccentric exercise without decreasing physical fitness.

Questions about this trial
What is this clinical trial studying?
A study testing Backwards running on a Treadmil with a negative slope in people with Achilles Tendinopathy, run by Meuhedet. Healthcare Organization at 1 site in Israel.
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 4 inclusion and 3 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 17 Nov 2020. 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 Israel. 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?
VISA-A questionnaire (time frame: baseline). The study lists 12 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 NCT04632979, which also lists 3 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 17 Nov 2020.
