Introduction: In CP, the lesion in CNS frequently results in spasticity of various muscle groups. Spasticity causes relative failure of muscle growth and deformation of joints over which spastic muscles work and may produce functional problems. Various techniques of soft tissue mobilization are adopted. In clinical setting slow and sustained static stretching is commonly followed, though MFR is also beneficial. Aim of Study: To study the immediate effect of stretching and MFR/ stretching alone on calf muscle spasticity in spastic diplegic patients. To compare the effect of stretching and MFR/Stretching alone on calf muscle spasticity in same population. Methodology: Study Design: Experimental study, Sample size: 18 Patients: Each group-9, Study setting: B1 Physiotherapy department, Civil Hospital, Ahmedabad. Duration of Study: Total duration of the study was 6 months. In the group A MFR, followed by static stretching in the form of SWB was given to the calf muscles, where as in group B only stretching was given. Outcome measures: Effect of intervention was seen immediately after the intervention by taking MAS and MTS. Results: Results of within group analysis, showed significant improvement in MTS R1 and MAS for both the groups, A and B at 5% level of significance, and showed no significant improvement MTS R2. Results of between the group analysis showed no significant improvements in MAS and MTS R2 but showed significant improvements in R1 value of MTS in Group A than group B at 5 % level of significance. Conclusion: Stretching can be used along with MFR in reducing spasticity in spastic CP patients rather than using stretching alone.
