Subacromial impingement syndrome (SAIS) is an umbrella term for a variety of inflammatory pathologies within the subacromial space. These include rotator cuff syndrome, bursitis, tendinopathy and calcific tendinitis. Conservative treatment is used to decrease inflammation, restore range of motion in the shoulder and strengthen the rotator cuff (Gebremariam et. al, 2013). Physiotherapy has shown to be an effective method for treating SAIS and should be considered as the first line of care (Dicken et. al, 2005). However, it is important to understand which therapeutic modalities should be prioritised and considered when treating SAIS.
There is a wealth of research suggesting to focus on scapular stabilization and rotator cuff strengthening when rehabilitating patients with SAIS. For example, Baskurt et. all investigated the effectiveness of scapular stabilization on pain, shoulder range of motion, joint position sense (JPS), scapular dyskinesis and quality of life in patients with SAIS. They discovered the combination of scapular stabilization, shoulder strengthening and stretching is the most effective method in improving JPS and decreasing scapular dyskinesis (Baskurt et. al, 2011). Michener et. al compared various treatments for SAIS (exercise, joint mobilisations, laser, ultrasound and acupuncture) in a systematic review. The evidence suggested laser therapy is only beneficial when used in isolation and there is no benefit in using ultrasound or acupuncture. However, the most effective treatment for SAIS is the combination of rotator cuff strengthening and scapular stabilisation alongside joint mobilisations (Michener et. al, 2004). Additionally, Celik concluded that patients with SAIS exhibited a lower visual analog scale score when exercises were performed within pain free range of motion (90 degrees and below). Overall research illustrates rotator cuff strengthening, scapular stabilization and joint mobilization are essential when treating SAIS. Furthermore, during the early stages of rehabilitation, prescribing exercises below 90-degree shoulder flexion can aid in pain management (Celik, 2009).
When creating a rehabilitation programme, practitioners should consider a patient-centered approach. It is important to recognize patients’ pain tolerance and threshold when prescribing exercises for SAIS. Vallés- Carrascosa et. al compared painful eccentric exercises (PEE) to pain free eccentric exercises when treating SAIS. Remarkably, PPE was found to provide no additional benefits. Therefore, practitioners should consider prescribing pain free exercises to promote compliance with rehabilitation programmes, especially for patients with a lower pain tolerance (Vallés- Carrascosa et. al,2018).
