Read the detailed description
Maintaining balance is an important skill that requires coordination and is crucial for human beings. The Central Nervous System (CNS) plays an important role in maintaining balance, postural stability, and postural correction in response to sudden perturbation. The subcortical brain region contributes to balance maintenance and postural stability is regulated by the cerebral cortex. Balance is defined as the "Body's ability to keep its center of gravity within the base of support either standing or walking". On a regular basis people encounter perturbations (traveling on a bus while standing) that challenge balance, to overcome unexpected perturbations there must be activation of postural muscles to maintain the center of gravity within the base of support and prevent fall. Individuals mostly use ankle strategy or hip strategy to recover from perturbation and prevent fall. Anticipatory postural adjustment is a critical component of postural stability. recently cognition and postural control have received attention, there are studies that claim that dual-task design has been used to show the relation between posture and cognitive functioning. In the dual-task paradigm two tasks are performed simultaneously to divert the attention of an individual to an external source (counting backward etc.) while performing another task. Divided attention is commonly required in daily life while performing dual tasking and multitasking activities, if attention is not properly divided among task it will results in decline in performance which causes impairment of balance and fall.To prevent this, balance must be recovered from perturbation. The purpose is to assess effect of cognitive loading and recovery from perturbations along with balance maintenance and fulfillment of research gap that study should be performed with multiple methods of cognitive loading. That's why different methods for cognitive loading are used in current study which shows that how varying levels of cognitive load influence postural stability and balance in dual-task conditions. This research can help in rehabilitation programs in which specific interventional designs and treatment protocols are made to improve balance under the influence of cognitive load. Provide awareness to people on a societal level to improve their balance and posture maintenance under a mental workload.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PerturbationOther
Jack is attached to force plates and it is used to give perturbation when participants are standing on force platform. Balance is assessed after perturbation and readings will be taken through HRV and GSR.
Working Memory TaskOther
Arithmetic test (Backward counting with serial 3 subtraction and articulation): participants are asked to count out loud backward with serial subtraction of 3 from each number, starting with a random number provided by the researcher. while participants are standing on force plates. During all this process cognitive loading will be measured through Heart Rate Variability (HRV) and Galvanic Skin Response (GSR).
Visual and Verbal Fluency TaskOther
Modified Stroop test or Stroop color word test: Participants are asked to name the color of ink that each word is printed. The test will appear on screen while participants are standing on force plates. During all this process cognitive loading will be measured through Heart Rate Variability (HRV) and Galvanic Skin Response (GSR).

Questions about this trial
What is this clinical trial studying?
A study testing Perturbation, Working Memory Task and Visual and Verbal Fluency Task in people with Balance and Cognitive Load, run by Riphah International University at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 25 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
