Conditions

Adhesive Capsulitis, Frozen Shoulder

Brief summary

This randomized exploratory clinical trial evaluated the effectiveness of the GDS Muscle and Joint Chains Method compared with conventional physiotherapy in patients with frozen shoulder (adhesive capsulitis). Thirty participants were randomly assigned to either the GDS intervention group or the conventional physiotherapy control group. Both interventions consisted of eight 50-minute sessions administered twice weekly for four weeks. The primary therapeutic objectives were to improve shoulder range of motion and reduce pain. Shoulder mobility was assessed using goniometry, and pain intensity was evaluated using a Visual Analog Scale. The study hypothesized that the GDS Muscle and Joint Chains Method would produce greater improvements in shoulder mobility and pain than conventional physiotherapy.

Interventions

OTHERGDS Muscle and Joint Chains Method

Participants received eight 50-minute sessions of the GDS Muscle and Joint Chains Method, administered twice weekly for four weeks. Treatment was individualized according to the participant's typology and included muscle reprogramming, postural and movement retraining, manual techniques applied along muscle-chain pathways, passive stretching, isometric and eccentric muscle activation, proprioceptive techniques, and strategies aimed at restoring balance between antagonistic and complementary muscle chains. Shoulder range of motion and pain intensity were assessed before and after the four-week intervention.

OTHERConventional Physiotherapy

Participants received eight 50-minute conventional physiotherapy sessions administered twice weekly for four weeks. Treatment included application of a hot compress to the affected shoulder, 15 minutes of conventional transcutaneous electrical nerve stimulation (TENS) at 150 Hz with intensity adjusted to participant tolerance, 10 minutes of therapeutic ultrasound at 3 MHz and 0.8 W/cm² in pulsed mode at 50%, followed by 15 minutes of therapeutic exercise according to the MEDBRIDGE GO program. Shoulder range of motion and pain intensity were assessed before and after the intervention.

Design outcomes

Primary

MeasureTime frameDescription
Change in Shoulder Range of MotionBaseline and 4 weeksShoulder range of motion was measured in degrees using goniometry. Measurements included shoulder flexion, abduction, internal rotation, external rotation at 90° of abduction, and external rotation at 0°.
Change in Pain IntensityBaseline and 4 weeksPain intensity was assessed using a Visual Analog Scale ranging from 0 to 10, with 0 representing no pain and 10 representing the greatest pain intensity.
