Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The purpose of this study was to determine whether current MTSS treatment methods with an adjuvant novel device are more effective in treating MTSS pain symptoms than the current treatment methods without the device.
The investigational device is an external orthosis comprised of a calf sleeve with 3 rubber ellipsoids that compressed the musculotendinous junctions of the soleus muscle with the aid of circumferential elastic strapping (posterior to fibular head, mid-diaphysis of posteromedial tibia, Achilles tendon). Another rubber component in the shape of a 10cm rod compressed the posteromedial border of the distal one-third of the tibia. It is therefore applied like a sock reaching from proximal tibial to distal tibia, it is worn up to 2hrs at a time before exercise and up to 2hrs after exercise each day and up to 4hrs in 2x2hr periods on days where no exercise takes place. Participants in the study completed weekly diaries that recorded device usage in detail. They wore the device and recorded device usage over a 6 month period.
Participants already engaging in treatment for their MTSS were not discouraged from continuing these activities. These included stretching and calf strengthening exercises, dry needling, rest, icing, orthotics for shoes. These were administered according to the physicians treating the patients prior to the study.

Treatment: Devices
Comparator / control treatment
The placebo device appeared visually identical, however, it lacked the functional rubber components of the true device. Therefore, it consisted of a spandex sleeve with 4 circumferential elastic straps that were tightened to apply firm pressure. Our research team believed this would be an ideal placebo as previous research has demonstrated there is no clinical benefit of using compressive garments for MTSS.

Eligibility
Key inclusion criteria
• Symptomatic medial tibial stress syndrome of at least 6 weeks duration, diagnosed on the basis of:
o History of diffuse, dull shin pain that is associated with exercise,
o Palpable tenderness of the posteromedial tibial border
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
• Diagnosis of stress fracture in the previous 6 months
• Clinical suspicion of a current stress fracture due to localised point tenderness on the anterior or medial border of the tibia unless ruled out by an MRI (MRI negative for bone stress reaction)
• Signs of plantar fasciitis including heel pain on first steps in the morning and tenderness to palpation over the posteromedial calcaneal tuberosity
• Previous diagnosis of compartment syndrome
• Suspicion of chronic exertional compartment syndrome on the basis of history of shin or calf pain brought on at a predictable point in activity, that worsens if exercise continues and is relieved by rest, unless excluded with compartment pressure testing
• Clinical signs of complex regional pain syndrome including pain out of proportion to the inciting event, allodynia, hyperalgesia, diffuse oedema, skin changes and difference in temperature between limbs
• Previous diagnosis of popliteal artery entrapment syndrome
• Clinical suspicion of popliteal artery entrapment syndrome based on disappearance of pedal pulses on repetitive plantarflexion
• Clinical suspicion of radicular leg pain including history of back pain associated with the leg pain and/or reproduction of leg pain on SLR testing with added dorsiflexion
• Neurological disease affecting the lower leg
• Coagulation disease
• Pregnancy

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Computer randomised participants with Central randomisation by computer to ensure allocation concealment. Devices were fitted on participants by a single clinician. Data was collected and analysed by a clinician blinded to group allocations of each participant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerized sequence generation

Efficacy
Statistical methods / analysis
Comparisons were made within groups at each time point using Wilcoxon signed-rank tests for categorical data. Comparisons between groups were made at each time point using Mann-Whitney rank-sum tests for categorical data and a Student’s T Test for continuous data. Bivariate Spearman’s Tests for correlation were conducted to determine a relationship between different variables. Ordinal logistic regression analysis was performed to identify variables that independently affected MTSS Scores at each time point in the study. The level of significance was set at p < 0.05 for all statistical analyses.
