Study summary

Study aiming at determining the efficacy of eccentric versus concentric exercises for improving tendon biological characteristics, pain, and shoulder overall function for rotator cuff tendinopathy in patients with Rheumatoid arthritis (RA).

Moreover, investigation the relationship between RA activity and the severity of rotator cuff tendinopathy.

Patients will be randomly assigned into either concentric or eccentric exercise group. Randomizations will be done using computer random generated numbers.

Study aiming at determining the efficacy of eccentric versus concentric exercises for improving tendon biological characteristics, pain, and shoulder overall function for rotator cuff tendinopathy in patients with RA. Moreover, investigation the relationship between RA activity and the severity of rotator cuff tendinopathy.

Patients will be randomizations using computer random generated numbers. patients will receive either eccentric or concentric exercises for internal, external rotators and abductors muscles All patient will do stretching for posterior capsule and pectoralis minor Tendon biological changes and subacromial space will be assessed using musculoskeletal ultrasonography Shoulder function will be assessed using SPADI (shoulder pain and disability index Pain will be assessed using Visual Analogue Scale (VAS) Rheumatoid arthritis disease activity will be assessed using Disease Activity Score-28 for Rheumatoid Arthritis with erythrocyte sedimentation rate (DAS 28 ESR) patient will be assessed at base-line and after finishing of the study

Study arms

  • Experimental
    Concentric exercises group

    patient will do Concentric exercises. Patients will receive 3 sessions per week for 4 weeks. Exercise will be done under the supervision of the same physical therapist. During each session. Exercise will be in the form of glenohumeral scaption, internal and external rotation exercises. patient will also do stretching for posterior capsule and pectoralis minor

What researchers measure

Primary outcomes

  1. Shoulder function

    shoulder Pain and Disability Index (SPADI): It is a self-reported questionnaire evaluating the function of the shoulder.

    Time frame: one month

Secondary outcomes

  1. tendon thickness, fibrillar pattern and echogenicity

    tendon thickness, fibrillar pattern and echogenicity as measured Ultrasonography

    Time frame: one month

  2. subacromial space

    shoulder subacromial space as measured by Ultrasonography

    Time frame: one month

  3. Pain measured by Visual analogue scale (VAS)

    pain as measured by Visual analogue scale which a 10 cm scale marked at the beginning zero indicating no pain and 10 at the end indicating worst pain

    Time frame: one month

  4. ESR

    Erythrocyte sedimentation rate

    Time frame: one month

  5. disease activity score 28 Erythrocyte sedimentation rate (DAS 28- ESR)

    disease activity score 28 Erythrocyte sedimentation rate High disease activity is defined as a DAS 28 ESR\>5.1, moderate activity as a DAS 28 ESR between 3.2 and ≤5.1, low activity as a DAS 28 ESR between 3.2 and \>2.6, and remission as a DAS 28 ESR less than 2.6

    Time frame: one month
