About this study

Official title: Analysis of the Effects of a 4-week Low-intensity Training With and Without Blood Flow Restriction in People With Rotator Cuff-related Shoulder Pain

This study aims to analyze the effects of 4 weeks of low-intensity exercise with and without blood flow restriction (BFR) on pain, fear of movement, catastrophizing about pain, strength, and disability in a population with rotator cuff-related shoulder pain. There are two modalities corresponding to the same exercises under different blood flow restriction conditions: 1) 3 low-intensity exercises (30% 1RM) with BFR (50% AOP); 2) 3 low-intensity exercises (30% 1RM) without BFR.

Participants will be randomly assigned to one of two groups and will undergo a 4-week intervention. The variables of interest will be assessed in each group for subsequent analysis and comparison.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Resistance exercise with BFRDevice

    Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a 50% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.

  • Resistance exercise without BFRProcedure or surgery

    Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a without flow restriction application (cuff applied without pressure). 30" rest between sets, 2' rest between exercises.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain intensity during movement (Visual Analogue Scale, 0-10)

    Pain intensity perceived on a Visual Analogue Scale during movement (flexion and abduction movement without load), being 0 no pain and 10 the worst pain imaginable.

    Measured: Baseline, 2 weeks, and 4 weeks.

Secondary outcomes (9)
  1. Pain intensity at rest (Visual Analogue Scale, 0-10)

    Pain intensity perceived on a Visual Analogue Scale, at rest, being 0 no pain and 10 the worst pain imaginable.

    Measured: Baseline, 2 weeks, and 4 weeks.

  2. Pressure pain threshold

    Pressure pain threshold measured in the middle deltoid (peripheral sensitivity) and tibialis anterior (central sensitivity), using an algometer.

    Measured: Before the session, immediately after, and 1 hour post-intervention

  3. Kinesiophobia

    Assessment of fear of movement or reinjury, assessed via the self-administered Tampa Scale of Kinesiophobia questionnaire.

    Measured: Baseline, 2 weeks, and 4 weeks.

  4. Occurrence of adverse effects

    Occurrence of adverse effects (e.g., pain, delayed onset muscle soreness, sudden weakness of the trained limb, redness or swelling of the trained limb, etc.) by self-report.

    Measured: Immediately after the intervention, 1 hour, 6 hours, 24 hours.

  5. Pain Catastrophizing

    Assessment of pain catastrophizing, measured using the self-report Pain Catastrophizing Scale (PCS), which evaluates exaggerated negative mental responses to actual or anticipated pain. The final score ranges from 0 to 52, with higher scores reflecting higher levels of catastrophizing.

    Measured: Baseline, 2 weeks, and 4 weeks.

  6. Pain and Disability

    Assessment of pain and disability, measured using the self-report Shoulder Pain and Disability Index (SPADI). The score ranges from 0 to 100. A score of 0 indicates best, 100 indicates worst. A higher score shows more disabillity.

    Measured: Baseline, 2 weeks, and 4 weeks.

  7. Shoulder Disability

    Assessment of shoulder disability, measured using the self-report Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH). The final score ranges from 0 (no disability) to 100 (severe/maximal disability), calculated from patient-rated difficulty on a 5-point scale for 30 items, with higher scores indicating greater impairment in arm, shoulder, and hand function.

    Measured: Baseline, 2 weeks, and 4 weeks.

  8. Muscle Strength

    Assessment of supraspinatus and internal and external rotator muscle strength, measured using a strap-secured handheld dynamometer.

    Measured: Baseline, 2 weeks, and 4 weeks.

  9. Satisfaction with methodology

    Assessment of participant satisfaction with the methodology used, measured at the end of the program using a 5-point scale: very satisfied (5), satisfied (4), neutral (3), dissatisfied (2), very dissatisfied (1).

    Measured: 4 weeks.
