简要总结
Blood flow restriction training is widespread in sport performance areas, where it has proven to be beneficial in strength and hypertrophy development. However, there are only few studies related to its effects on subjects with pathology, and currently, there is no recent clinical trial evaluating its effects on patients with RCRSP. We are aiming to define the potential benefits, acute and short-term effects of adding blood flow restriction to a low-load exercise training for patients with RCRSP.

入选标准
- •Pain around the antero-lateral (deltoid area) region of the proximal shoulder during active movements in abduction and/or external rotation.
- •3/5 positive impingement tests: Neer, Hawkins-Kennedy, empty can, painful arc, and resisted external rotation or abduction.
- •Pain at rest less than 3cm in a visual analogue scale (VAS).
排除标准
- •Previous shoulder surgery.
- •Being treated with physical therapy or pharmacogical therapy for shoulder pain.
- •External rotation range of motion less than 45º or 50% compared to the contralateral side.
- •Suspected shoulder instability (previous dislocation/subluxation, sulcus sign, anterior drawer test, anterior/posterior aprehension test, relocation test).
- •Suspected cervical radiculopathy (distraction, spurling, ULNT1, squeeze test, ipsilateral rotation less than 60º)
- •Presence of neck pain.
- •Suspected rotator cuff tears (drop arm test, external rotation lag sign, diagnostic imaging).
- •Contraindications to blood flow restriction therapy.
