ABSTRACT
OBJECTIVES: Osteoarthritis (OA) is the most prevalent and disabling joint disease in the world. Temporomandibular joint (TMJ) exercise is a widely used treatment and could be a beneficial and long-term tool for treating TMJ OA. The present study aims to evaluate the effects of therapeutic exercise in the conservative treatment of TMJ OA. MATERIALS AND METHODS: A single-group experimental pre-post test was performed. We included patients who met the diagnostic criteria for TMJ OA. Outcome variables were pain intensity (visual analogue scale), functionality (Helkimo index), and structural changes (ultrasound). Follow-up periods were at months 1, 3, and 6. The intervention included a home-based program with thermotherapy, manual therapy, and therapeutic exercise during the entire follow-up period. RESULTS: We included 15 patients and 26 joints, all women with a median age of 57 years (range, 49-62 years). Median change in pain intensity on joint palpation, mouth opening, and at rest at the first month was 47.5 mm, 51 mm, and 60 mm, respectively, and 48 mm, 49.5 mm, and 42.5 mm, at six months (P=0.001). The Helkimo index showed significant improvement in medians from baseline severe dysfunction (17 points) to minimal dysfunction at three and six months (2 points) (P=0.001). Ultrasound showed improved disc position. CONCLUSION: This study demonstrated significant improvements in pain, function, and joint disc position and represents a valuable tool for the long-term treatment of patients with TMJ OA.
ABSTRACT
INTRODUCTION: Rotator cuff tears are the main cause of shoulder pain and disability. First line of treatment is conservative; there is evidence regarding the advantage of using eccentric over concentric exercises in tendinopathies, but there are no evidence-based recommendations on starting strengthening exercise during painful phases nor on the effectiveness and advantages of eccentric vs. concentric exercise in rotator cuff tears. OBJECTIVE: To evaluate the tolerance of a resistance strengthening program and to compare eccentric vs. concentric programs. DESIGN: A pilot, experimental, randomized controlled study. SETTING: Outpatient Rehabilitation Center. PATIENTS: Twenty-six patients with a diagnosis of partial rotator cuff tear were randomly assigned to: the experimental group (eccentric, n = 12) and the control (concentric, n = 14). INTERVENTION: The experimental group performed muscle strengthening with eccentric technique directed to shoulder and scapular girdle muscles, while the control group performed the concentric technique. MAIN OUTCOME MEASURES: Visual Analogue Scale (VAS), Constant Scale, Strength, Structure (Ultrasound report). RESULTS: The tolerance rate was 96% in both groups. Median age (experimental vs. control) was 54.5 vs. 54 years (p = 0.69). Results at baseline, and at months 1, 3, and 12 (median) were as follows: for VAS (mm), experimental: 55, 30, 30, and 10, p < 0.001 (intra-group); control: 50, 30, 30, and 5, p = 0.01; Constant scale (points): experimental 58.5, 88, 93, and 85, p < 0.001; control 50.62, 80, and 91.5, p = 0.038; normalized strength (Kg); experimental: 0.23, 0.29, 0.73, and 0.72, p = 0.001, and control: 0.24, 0.21, 0.54, and 0.66, p = 0.01. We found inter-group differences in the Constant scale at 1 and 3 months (p < 0.05), and in strength at months 1 and 3 (p < 0.05). We observed structural differences in tendon (healing) between groups at 3 and 12 months. CONCLUSIONS: Eccentric and concentric strengthening were well tolerated; both show early improvement in pain, functionality and tendon structure. Eccentric training appears to be more effective than concentric in the early improvement of functionality, strength and tendon healing.
ABSTRACT
OBJECTIVE: To propose and evaluate the effectiveness of a telerehabilitation platform designed for patients with rotator cuff (RC) tears. METHODS: During the first study phase, a virtual service platform that included information on RC tear pathology, joint care, and a series of instructions regarding therapeutic exercise was designed and created. Subsequently, in the clinical phase, a quasi-experimental study was performed. The platform was tested on patients and evaluated at baseline and at 1, 2, 3, and 6 months with respect to their pain levels and functionality on the Constant-Murley (CM) scale. RESULTS: Eleven patients were included, 5 women and 6 men, with a median age of 55 years (range, 42-68 years). Pain diminished from a baseline value of 64 mm (range, 40-80 mm) to 16 mm (range, 0-30 mm) at 6 months (p<0.001). Points on the CM scale rose from a baseline value of 54 points (range, 51-66 points) to 85 points (range, 70-100 points) at 6 months (p=0.001). Functionality in daily living and work activities, movement, and strength exhibited significant changes at 6 months (p<0.05). CONCLUSION: Significant changes were observed in pain and functionality in this group of participants who used a telerehabilitation platform. To the best of our knowledge, this is the first study that included a specific program for RC tears.
