Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be recruited through advertisements in the local press and from local physiotherapy or GP practices. The principal investigator will assess subjects against inclusion/exclusion criteria and subjects meeting the criteria will be passed on to the clinic receptionist. Concealed allocation will be carried out by the receptionist who asks the patient to draw from 40 sealed opaque envelopes and arranges an appointment with the treating therapist.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated list will be used to randomize subjects meeting the inclusion criteria into one of two groups, Laser or Placebo. The clinic administrator will be responsible for randomisation, after the subject has given informed consent. The laser equipment is to be fitted with a switch marked “1” or “2” to indicate placebo or active laser; only the principal investigator will know which position is active. The treating physiotherapist will only be aware that 40 subjects are to receive LLLT at 3J per point, with the laser switched to “1” or “2” as per the treatment sheet.

Summary
Brief summary
The primary aim of this study is to get an idea of whether Low-Level Laser Therapy (LLLT) may be effective in the management of Achilles Tendinopathy, and give benefit to the patients over and above that of eccentric exercises alone. The Hypothesis is that the treatment group will have less pain and more improvement in functional outcome measures score compared to the control group.
