Outcomes
Primary outcome [1] 259648 0
A reduction of peak plantar pressure of 10 N/cm2 at the foot. Peak pressure will be measured with the Pedar-X mobile in-shoe plantar pressure system (Novel gmbh, Munich, Germany). The Pedar-X is the gold standard in plantar pressure assessment in diabetes and is non-invasive.
Timepoint [1] 259648 0
Baseline
Day one after intervention
Six- weeks after intervention
Secondary outcome [1] 266310 0
An increase of 10 degrees of range of motion of the ankle and big toe joints. Range of motion, will be measured using standardised clinical measurement procedures with degrees of motion read from a goniometer. A standardised lunge test will also be used to measure ankle joint range with a goniometer, and a ruler to measure distance of the foot from the wall.

adolescents with diabetes of at least one year duration
Minimum age
13 Years
Maximum age
17 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Major musculoskeletal problems which result in atypical walking patterns, the use of walking aids and
previous ulcerations. Back injuries/ pain and neurological deficiencies in the foot were stretching may be

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed opaque envelopes will be used for concealed allocation so that the person who determined if a subject was eligible for inclusion in the trial was unaware, when this decision was made, and to which group the subject is allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e., computerised sequence generation)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
Adolescents with diabetes display limited joint mobility. Because of the association with high pressures under the feet, poor sensation and foot ulceration with disease progression, limited joint mobility assessment is a standard procedure in diabetic foot care. Clinical interventions to
reduce high pressures under the feet include orthoses, footwear and surgical correction. While stretching
has been reported to improve ankle joint range of motion in the general population, limited evidence is available for individuals with diabetes. The evidence for calf stretching in
adolescents where prevention of contractures and high plantar pressures in the early stages of disease may be most beneficial have not been investigated. This study will use a randomised control study to investigate the efficacy of stretching on the ankle and big toe joints to reduce high pressures under the feet and contractures of the ankle and foot joints.
