Public title
Utility of ultrasound when using shock wave therapy to treat painful calcification in shoulder tendons, achilles tendons and plantar fasciitis with heel spur.
Scientific title
Randomised controlled trial comparing ultrasound-guided to patient-guided extracorporeal shock wave therapy (ESWT) for calcific soft tissue pathologies (including tendinopathy) when assessing patient outcomes of decreased pain, improved function and reduced calcification size.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All patients will receive active treatment i.e. shockwave therapy, with the SHOCK WAVE THERAPY PROTOCOL described as below:

1. NUMBER & FREQUENCY OF TREATMENT SESSIONS:
3-5 treatment sessions.
Treatment sessions will be spaced at 1 week intervals.
(NB.Number of sessions of treatment are based on patient's response to treatment. All patients will receive 3 treatment sessions. Patients who feel they have not had a decrease in their pain or improvement in function can have an additional 2 treatment sessions).

2. DURATION OF TREATMENT SESSIONS:
Each treatment session will take between 20-30mins depending on the arm of the study.
Arm 1 (patient-guided shockwave treatment) will take about 20 mins. Arm 2 ( ultrasound-guided shockwave treatment) will take about 30 mins with the additional 10 mins needed to locate the calcification on ultrasound prior to treatment. All session times also include filling out questionnaire prior to treatment, setting up the patient for treatment and arranging the follow up appointment or answering any questions. The shockwave treatment itself takes less than 5 mins.

3.SHOCKWAVE MACHINE SETTINGS:
2000 Impulses, 20 Hz , over a range of 1.4-2 bar.

4. THE TWO STUDY ARMS OF PARTICIPANTS:
Arm 1: Patient-guided shock wave therapy to the area where the most pain is felt in relation to the area of calcification.
Arm 2: Ultrasound-guided shock wave therapy to the exact site of calcification.

Treatment: Other
Comparator / control treatment
Shockwave therapy protocol: 3-5 sessions, at 1 week intervals. Shock wave settings at: 2000 Impulses, 20 Hz , over a range of 1.4-2 bar.

Active control: (Arm 1 as above) patient-guided shockwave therapy to the area where the most pain is felt in relation to the area of calcification.
Control group
Active

Outcomes
Primary outcome [1] 286599 0
Patient pain - using a 10 cm visual analogue scale

Eligibility
Key inclusion criteria
Pain in one of 3 areas - either shoulder rotator cuff tendon, achilles tendon or plantar fascia; Proven calcification visible on previous imaging;Calcification visible on our ( the investigator's) ultrasound machine; Males and non-pregnant females; fluent in english; able to give informed consent; seeking to try shockwave treatment as a method to resolve the pain; willing and able to follow the research protocol
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Calcification unable to be seen on our ( the investigator's) ultrasound machine; unable to follow the protocol; unable to tolerate the shock wave treatment according to the protocol because it is too painful; corticosteriod injection to the area inthe last 3 months ( as this may affect treatment efficacy); pregnancy or suspected pregnancy during the study; cancer; local lesions or non-intact skin; osteoarthritis at treatment site; Polyneuropathy; bleeding or clotting conditions; anticoagulation medications; allergy to ultrasound gel.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Letters of recruitement for study will be sent to health care professionals (eg. orthopaedic surgeons, general practitioners, sports medicine doctors, podiatrists). Patients fitting inclusion criteria will be referred to our clinic. Referred, voluntary patients eligible for the study will be randomly allocated to either the "patient-guided" or "ultrasound guided " . Allocation will be by concealment in opaque envelopes. The person giving the shock wave therapy and the patient will not be aware as to which group the patient is in until the envelope is opened prior to the first shock wave treatment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation. Randomisation done by generating three random number lists (based on site of calcification either shoulder, achilles or plantar fascia) using an excel computer programme. Numbers in each list allocated to either arm 1 ( patient-guided shock wave therapy) or arm 2 ( ultrasound-guided shock wave therapy). Treatment arm put in an opaque envelope. Envelopes numbered sequentially on the outside according to participant number at presentation for treatment.
