Evaluating the role of muscle energy technique for gastro-soleus tightness in plantar fasciitis management

Abstract

Introduction: Plantar fasciitis (PF) is a prevalent musculoskeletal disorder primarily presenting with heel pain often associated with tightness in the gastrocnemius-soleus complex. Muscle energy technique (MET), a form of manual therapy, has shown promise in addressing muscular tightness and improving flexibility. Objective: To evaluate the effectiveness of MET in reducing gastro-soleus tightness, alleviating pain, and improving functional outcomes in individuals with Plantar fasciitis. Methods: A total of 33 subjects diagnosed with plantar fasciitis were randomly allocate into either, METs group (n = 17) treated with muscle energy technique at the gastro-soleus muscle complex or conventional group (n = 16) received standardized treatment. The baseline pre-test measurement for pain and function were assessed and recorded using numeric pain rating scale (NPRS) and the foot function index (FFI) respectively and the same was recorded as post-test after two weeks of intervention. Results: The METs group showed a statistically significant reduction in pain and improvement in functional outcomes, with a mean NPRS difference of 4.3 (p <0.001) and an FFI difference of 35.7 (p <0.001). Effect size analysis indicated a larger effect, suggesting strong clinical relevance of the intervention. Conclusion: The application of Muscle Energy Technique to the gastro-soleus muscle complex resulted in significant pain reduction and improved functional outcomes in individuals with plantar fasciitis. These results support incorporating METs into standard physiotherapy protocols for more effective management of plantar fasciitis.
