PNF in Subacromial Impingement Syndrome

Ankara Yildirim Beyazıt University45 enrolled

Overview

Although proprioceptive neuromuscular facilitation (PNF) techniques have been used in the treatment of different shoulder problems, PNF techniques in scapular and upper trunk patterns with extremity pattern have not been considered as a possible option for the treatment of Subacromial Impingement Syndrome (SIS). The aim of this study was to evaluate the effects of different PNF patterns in SIS.

This randomized controlled trial was conducted in the Outpatient Clinic of a Physiotherapy and Rehabilitation Department in Ankara, Turkey. The demographic and clinical characteristics of the patients were recorded. Voluntary patients with SIS were regarded as eligible for the study if they met the inclusion criteria. Pain, posture and functionality were assessed before and after intervention. Patients who met the inclusion criteria and agreed to participate were randomly allocated to Group 1 \[Conventional therapy (CT)\], Group 2 \[CT+ PNF in extremity pattern\] and Group 3 \[CT+ PNF in extremity pattern+PNF in scapula and upper trunk patterns\]. A simple randomization method was used with opaque sealed envelopes containing "A", "B" or "C". Group allocation was performed by an independent therapist, not involved in the study. All patients received physiotherapy for approximately 60 mins each session, 3 sessions per week for 6 weeks. Conventional therapy consisted of cold pack (15 minutes); pulsed ultrasound therapy (1 watt/cm², 3 MHz, 1:2 pulsed mode; 3 minutes); transcutaneous electrical nerve stimulation (60-120 Hz; 20 minutes) and exercises (20 minutes). The exercises included stretching, strengthening and posture exercises. The exercises, and the duration and intensity of conventional physiotherapy were selected according to previous studies which showed that a physiotherapy program 3 times a week for 6 weeks was effective in improving function and relieving pain in SIS. The physiotherapy program was applied to all patients at the same intensity by the same physiotherapist and patients did the exercises every day throughout the 6-week period. The patients were also advised to avoid overhead activities.

Outcomes

Primary Outcomes

Scapular stability

The lateral scapular slide test (LSST) was applied to evaluate scapular stability. In the first position (LSST 1), both arms are relaxed at the sides with the glenohumeral joint in a neutral position. In the second position (LSST 2), the subject places both hands on the ipsilateral hips with the humerus in medial rotation in 45° of abduction in the coronal plane. In position 3 (LSST 3), the subject actively extends both elbows and places the upper extremities in a position of maximum medial rotation in 90° of abduction in the coronal plane. The inferomedial angle of the scapula is palpated and marked on both the affected and unaffected sides, and the spinous process of the thoracic vertebra in the same horizontal plane (the reference vertebra) is then marked. The measurements from the reference point on the spine to the medial border of the scapula are measured on both sides in all 3 test positions.

Time frame: Change from baseline scapular stability at 6 weeks

Anterior tilt of the head

The distance was measured from the sternal notch to the tip of the chin with a tape measure.

Time frame: Change from baseline anterior tilt of the head at 6 weeks

Rounded shoulder

The subject stood in a relaxed position with their heels against a wall. The posterolateral acromion was marked and the ruler was held square. The measurement was taken from the acromion to the wall behind the subject to determine the amount of forward displacement.

Time frame: Change from baseline rounded shoulder at 6 weeks

Thoracic kyphosis

The gravity-dependent inclinometer (BASELINEᴿ Bubble inclinometer-USA) was used to measure kyphosis. In the first measurement, the inclinometer was placed over the region of the 1st and 2nd thoracic spinous processes and in the second, over the region of the 12th thoracic and 1st lumbar spinous processes. The total of the angles in each measurement was recorded.

Time frame: Change from baseline thoracic kyphosis at 6 weeks
