Summary

The goal of this randomized controlled trial is to compare the integrity of somatosensory processing with transcranial magnetique stimulation (TMS) and corticospinal excitability of the affected shoulder in individuals with adhesive capsulitis versus healthy controls. The secondary objective is to compare the clinical and neurophysiological effects of an intervention using tendon vibration (VIB) to induced kinesthetic illusions. This will involve comparing two groups: one receiving a real intervention versus a placebo intervention protocol, both coupled with standardized exercises in individuals with capsulitis. The hypotheses are that the proprioceptive processing and corticospinal excitability are impaired in the presence of capsulitis, and that the VIB + exercises intervention will result in greater improvements than the placebo VIB + exercises. To goal is to establish the first empirical foundations for understanding adhesive capsulitis, using cutting-edge neurophysiological investigation technologies. TMS will be used to explore the presence of maladaptive plasticity in motor networks by assessing the excitability and integrity of the primary motor cortex (M1) and the corticospinal tract. Recruitement: 30 healthy participants and 30 participants with a diagnosis of adhesive capsulitis will undergo 2 baselines assesments, 6 interventions with tendon vibration and 2 follow-up evaluation. Participants will be age- and sex-matched. Baseline and follw-up include: * Questionnaires : SPADI, QuickDASH, French version of the Mcgill Pain Questionnaire; * Active and passive range of motion; * Ultrasound for diagnosing capsulitis. Comparison parameters: * active motor threshold (aMT) * Motor evoked potential (MEP) latency and amplitude * Standardized kinesthetic illusion procedure (SKIP) : direction of illusion, clearness, amplitude/speed. Interventions : * 2 baselines including all questionnaires, ultrasound, active and passive range of motion, TMS procedure and SKIP; * 2 VIB interventions per week, for 3 weeks * Real VIB : 80Hz of vibration to induce kinesthetic illusions, * Placebo VIB : 40Hz of vibration that does not induce kinesthetic illusions * 2 follow-up including all questionnaires, ultrasound, active and passive range of motion, TMS procedure and SKIP.

Conditions

• Adhesive Capsulitis of the Shoulder
• Frozen Shoulder

Interventions

Type	Name	Description
DEVICE	Tendon Vibration	Vibration can create kinesthetic illusions when applied at some modalities. The vibration will be put at 80 Hz and 1 mm of amplitude for 10 seconds to create 1 illusion/minute, during 20 minutes. Two interventions per week, for three weeks. Total : 6 interventions
OTHER	Exercices	Standardized exercise protocol, performed daily for 3 weeks, with a diary.
DEVICE	Tendon vibration	Tendon vibration will not induce kinesthetic illusions, since it will be applied 40 Hz and 1 mm of amplitude for 10 seconds. Two interventions per week, for three weeks. Total : 6 interventions
