Sensorimotor Training Exercises for Shoulder Position Sense

Overview

Forty-six female patients aged 35-55 years who were suffering from shoulder dysfunction following mastectomy surgeries participated in this study. The participants were recruited from the outpatient clinic of the Faculty of Physical Therapy, Cairo University, and were randomly assigned into two equal groups. Group A: consisted of 23 patients who received sensorimotor training exercises in addition to a traditional physical therapy program which included shoulder range of motion exercises, capsular stretching exercises, scapular muscle strengthening exercises, shoulder Maitland mobilization, and scapular mobilization. Group B: consisted of 23 patients who received only the traditional physical therapy program, which included shoulder range of motion exercises, capsular stretching exercises, scapular muscle strengthening exercises, shoulder Maitland mobilization, and scapular mobilization. Both groups received treatment three sessions per week for a duration of eight weeks.

1. Subjects Forty-six female patients aged 35-55 years who were suffering from shoulder dysfunction following mastectomy surgeries participated in this study.

The treatment was administered three sessions per week for eight weeks. 2. Equipment Therapeutic equipment Sensorimotor training exercises: Patients performed sensorimotor training exercises that included tracking a diagram fixed on the wall using a laser pointer, throwing and catching a medicine ball, performing upper-limb weight-bearing exercises on a Swiss ball, and executing wall exercises using a ball. The exercises were applied with a dosage of three sets of ten repetitions, with one minute of rest between sets, three times per week for eight weeks. Traditional physical therapy program: The traditional physical therapy program was conducted three sessions per week for eight weeks and included scapular retraction exercises with moderate resistance from standing, shoulder range of motion exercises using a shoulder wheel and ladder in flexion and abduction, scapular mobilization from sitting, shoulder Maitland mobilization as inferior, anterior, and posterior glides, and posterior capsule stretching from sitting with approximately two sets of fifteen repetitions. Measurement equipment Digital inclinometer: A digital inclinometer was used as a precise, gravity-based instrument to measure joint angles and range of motion (ROM) with high accuracy. It provided real-time digital readings, making it a reliable and efficient alternative to traditional goniometers. Clinically, it was commonly used to assess joint mobility of the spine, shoulders, hips, and knees, aiding in the evaluation of conditions such as arthritis, ligament injuries, and postoperative stiffness. In addition to ROM assessment, the digital inclinometer was considered a validated tool for evaluating joint position sense (JPS), a key component of proprioception. It was used to measure patients' ability to replicate joint angles, helping to identify neuromuscular control deficits frequently observed in musculoskeletal injuries and post-surgical cases. The objective data obtained supported individualized rehabilitation planning, progress monitoring, and functional recovery. Its portability, ease of use, and high reproducibility made it a valuable instrument in both clinical and research settings.
