Abstract: Background: Bimanual Therapy aims at using both arms and increasing the coordination between the paretic and non paretic hand. Symmetrical tasks demand equal participation by both the limbs. Complexity of the task is increased by adding load on the non paretic hand that increases the muscular activation on the paretic side, smooth. Rhythmic auditory cues given by a metronome sets up the bimanual task frequency, increases attention and gives sensory feedback. External sources of feedback are crucial in motor learning as it acts as important source to produce knowledge of result and knowledge of performance. Methods: 20 Stroke survivors were assigned to one of the 2 treatment groups: (1) Loaded Bimanual Therapy (2) Loaded Bimanual Therapy with Rythmic Auditory Cueing. They completed 14 sessions lasting 45 minutes, using 5 symmetrical active bimanual tasks each set done for 5 minutes each. Results: Both the treatment groups showed statistically significant improvements in the pre post analysis, but in intergroup analysis no statistical significance in any of the outcome variables was noted except for 6MWT distance covered p=0.013. Conclusion: Loaded Bimanual Therapy and loaded Bimanual Therapy with Cue are equally effective to bring out significant improvements in Upper Limb function, Trunk Function, Balance, Gait and functional capacity of 6MWT when compared to conventional therapy in stroke patients.
