The Efficacy of Eccentric Training Versus Concentric Training Along With Therapeutic Ultrasound Therapy for Pain and Functioning in Subjects with Lateral Epicondylitis
Keywords:Lateral Epicondylitis , Eccentric Exercise , Concentric Exercise.
Background: Lateral Epicondylitis is a disabling musculoskeletal condition leading to pain and/or tenderness
around the elbow. A common presentation may show pain and tenderness over the lateral epicondyle of the
humerus , the radial head , the fascia , between the origins of extensor muscles as well as radiating into the
Materials & Methodology: Patients with Lateral Epicondylitis (n=20) were included in this study and
patients with fracture of upper limb , radiculopathies , undergoing steroid therapy , rheumatoid arthritis
were excluded from the study. A comparative study was done where two groups were made , Group A
(n=10) received Eccentric exercise along with Ultrasound Therapy and Group B (n=10) received Concentric
exercise along with Ultrasound Therapy. Treatment was given for 3 times a week for 3 weeks. Pain was
assessed using Numerical Pain Rating Scale and functional disability was assessed using Patient Rated
Tennis Elbow Evaluation.
Results: Group A showed significant decrease in pain and functioning as compared to Group B. Mean pre
NPRS of eccentric subjects was 6.70 which was significantly higher than mean post NPRS 6.30 (p<0.001).
Mean pre NPRS of concentric subjects was 6.30 which was significantly higher than mean post NPRS 2.60
(p<0.001). Mean pre PRTEE of eccentric subjects was 53.90 which was significantly higher than mean post
PRTEE 12.85 (p<0.001). Mean pre PRTEE of concentric subjects was 55.45 which was significantly higher
than mean post PRTEE 23.50 (p<0.001)
Conclusion: The study concluded that Eccentric exercise along with Ultrasound Therapy is more effective
than Concentric exercise along with Ultrasound Therapy.
