Balance is controlled through a complex process involving sensory, visual, vestibular and cerebral functioning which get affected by various neurological disorders such as in stroke. Different types of exercises are designed to target to cope up with the imbalance developed due to these neurological disorders. This study aimed to compare the efficacy of dual-task training using two different priority instructional sets in improving gait parameters such as self-selected velocity, fast speed, step length, and stride length in chronic stroke patients.
Balance is controlled through a complex process involving sensory, visual, vestibular and cerebral functioning which get affected by various neurological disorders such as in stroke. Different types of exercises are designed to target to cope up with the imbalance developed due to these neurological disorders. This study aimed to compare the efficacy of dual-task training using two different priority instructional sets in improving gait parameters such as self-selected velocity, fast speed, step length, and stride length in middle cerebral artery chronic stroke patients. A total of thirty middle cerebral artery chronic stroke patients were recruited on the basis of inclusion and exclusion criteria and equally allocated into two groups. Group 1 received dual-task training with fixed priority instructional sets for four weeks and group 2 received dual-task training with variable priority instructional sets for four weeks. The outcome was assessed using a 10-meter walk test and the comparison of footprints on the walkway paper before and after training.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Dual-task Training Fixed Priority | Experimental | Dual-task Training with fixed priority instructional set for four weeks. Balance training sessions of 45 minutes per day, 3 times a week for four weeks, so as to complete 9-12 hours of training warm-up improve the balance performance. This included 12 repetitions in each session for 30 minutes after a 10-minutes warm up. Attention was focused on both postural and cognitive tasks throughout this session. In postural tasks, subjects were instructed to perform the following: walk narrow base of support with a cognitive task of counting backward by three walk narrow base of support with cognitive task of count forward by three, walk narrow base of support, step, sideways, backward avoiding the obstacles (holding a basket) with cognitive task to remember words. |

| Dual-task Training Variable Priority | Active Comparator | Dual-task Training with variable priority instructional set for four weeks. Balance training sessions of 45 minutes per day, 3 times a week for four weeks, so as to complete 9-12 hours of training warm-up improve the balance performance. This included 12 repetitions in each session for 30 minutes after a 10-minutes warm up. During the first half of the training session, attention was focused on postural tasks, while during the remaining half of the session, attention was focused on cognitive tasks. |

| Dual-task Training Variable Priority | Behavioral | Dual-task training variable priority instructional set for four weeks. Balance training sessions of 45 minutes per day, 3 times a week for four weeks, so as to complete 9-12 hours of training warm-up improve the balance performance. This included 12 repetitions in each session for 30 minutes after a 10-minutes warm up.

It is used to identify the patient's mobility with respect to healthy elderly subjects, such as the gait parameters and walking endurance in subjects with chronic stroke.The TUG score correlates with gait speed, balance, functional level, ability to go out, and this score can change over time.
