Description of intervention(s) / exposure
This study is a randomised cross over experiment in which participants will complete a standardised sub maximal hopping task of 10 single leg hops on a portable force plate under 4 different conditions in random order. Participants will be asked to self pace a series of 10 hops at their own natural hopping frequency. Participants will be asked to hop submaximally in bare feet (easy self paced hops) and wear loose sports clothing. The intervention will be administered by a Physiotherapist. No specific training is required to administer the hopping tests or auditory input by the Physiotherapist. The four conditions will be 1) Hopping with no auditory feedback 2) Hopping with auditory input that suggests enhanced functional capacity of the tendon (Spring sound) 3) Hopping with auditory input that suggests impaired functional capacity of the tendon (wet cement sound) and 4)hopping with non-informative auditory input. Speakers will be connected to a laptop and positioned either side of the force plate. For the control condition white noise will be played through the speakers as the participant hops. For the two informative auditory trials the timing of the sound will be matched to their hopping frequency. The washout period will be 15 minutes. Participants will be blinded to the study hypotheses and order will be randomised and counterbalanced across condition. The physiotherapist will use a checklist to adhere to the specific protocol. All records and notes will be checked by a study supervisor. The intervention session will take approximately 1 hour.

Outcomes
Primary outcome [1] 324210 0
Pain intensity while hopping measured using the Visual Analogue Scale for Pain (VAS) will be the primary outcome used in this study.
Timepoint [1] 324210 0
Participants will be asked the rate the maximal pain intensity experienced while hopping Immediately on completion of the task.
Secondary outcome [1] 384075 0
A leg stiffness estimate while hopping will be calculated using force plate data collected during the trial
Timepoint [1] 384075 0
leg stiffness will be calculated during the hopping task
Secondary outcome [2] 384076 0
Time to ease. After completing each set of single leg hops the participant will be asked to sit and record their time for pain to return to baseline. They will be provided with a timer and instructed to press stop when pain intensity reaches the baseline level.
Timepoint [2] 384076 0
Immediately post testing.

Eligibility
Key inclusion criteria
Participants will be included if they are a recreational runner with a history of unilateral mid portion Achilles tendinopathy for over 1 month. Participants must have sufficient English language skills to complete the questionnaires and be able to give consent to the test procedure. They must have normal hearing so that they can undertake the auditory feedback conditions. In addition the participants' Victorian Institute of Sports Assessment self-administered Achilles (VISA-A) score must be below 80
Minimum age
18 Years
Maximum age
60 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Insertional AT will be excluded from this study. People with a non-painful hop test will also be excluded from the study. Participants with a history of foot or ankle injury or surgery within the previous six months or any coexisting lower quadrant musculoskeletal problem will be excluded. Participants with any report of clinically significant low back pain within the previous 3-months will also be excluded. Participants with active systemic disease such as diabetes or an inflammatory disorder and those taking regular analgesic medications will be excluded.
