Stroke is a neurological insufficiency which causes major motor deficits particularly in lower limbs. Task oriented walking intervention is a novel approach used for stroke rehabilitation. The purpose of this research study was to compare the effects of the task oriented walking interventions with the conservative rehabilitation for improvement of balance in the chronic stroke patients. The study was a randomized control trial, conducted in hospital settings. 48 patients with predefined inclusion and Exclusion criteria were selected. Subjects were randomly allocated into 2 groups. After obtaining consent, data was collected via self-structured questionnaire, 06 minutes-walk test, Timed “Up and Go” test, and Berg Balance Scale. Group one received Task-Oriented Walking Intervention interventions and conventional treatment while control group received conventional interventions only. Data was analyzed by SPSS version 24. The results showed that, there were 54% males and 46% females. After 6 weeks of intervention experimental group receiving task oriented training along with conventional interventions showed significant improvement in balance with P-value <0.005 for all the three scales TUG, BBS and 6MWT as compared to the control group receiving only conventional interventions. Our respective study concluded that patients who were receiving task oriented walking interventions had considerable improvement in balance.

Stroke is a medical condition in which death of the brain cells occur due to poor blood flow to the cells of the brain [1]. Stroke has been defined in 1970 by World Health Organization (WHO) as a neurological insufficiency of the cerebrovascular cause that can persist after 24 hours or it may be disturbed by the death of the patient within 24 hours or more than 24 hours, or it may cause death with no evident reason [2]. The reasons for stroke may include the vascular insufficiency, cerebral infection, subarachnoid hemorrhage and or intracerebral hemorrhage. Stroke or CVA is considered as a leading cause of death and disability, having durable adverse effects on the affected population [3]. Generally, stroke is a medical condition that occurs due to poor blood flow to the brain and it can cause the damage to the cells of brain and it may also cause the permanent death of the cells of the brain. So, stroke is actually a neurological lesion that can lead to the physical, social, cognitive and other behavioral symptoms [4]. The stroke survivors may suffer from a number of the physical impairments like muscular weakness, loss of motor functions or motor insufficiencies, limited Range of movements, and a complete dependency on others even for basic ADLs [5]. Many patients have to face long lasting disabilities and are unable to make full progress towards their movement and functions ever. The usual outcomes of stroke include the sensory as well as the motor deficits and dysfunctions of the affected extremity but the most frequent are the motor deficits or the dysfunctions [6]. Stroke survivors who have lower limb dysfunctions or deficits are most influenced in performing the ADLs independently because they are bed ridden or wheel chair bound usually and have many gait and balance issues[7]. Conservative management for stroke may include the rehabilitation which further incorporates the brainstorm methodology, PNF, NDT and many other rehab exercises [8]. Stroke patients who have upper extremity dysfunction are notably susceptible to the issues in performing ADLs due to the motor deficits and the impairments. While the condition is even worse for the patients having lower extremity dysfunctions and usually such patients are bed ridden or wheel chair bound [9]. It is the need of the time to devise and progress new methodologies and strategies for rehabilitation of stroke in order to assist the affected population to achieve high level of the functional and purposeful independence in movement [10]. Task oriented walking intervention is one of the novel approaches and it might be capable of improving the functions of lower extremity motor functions in the people affected with stroke [11].

Task oriented walking intervention is a group of ten interventions which include the interventions designed specifically to improve the lower extremity functional status [12]. In the task oriented walking interventions, the patient is advised to perform the task in the prescribed setup and it provide the chance to effort with the techniques based on the specific tasks by making definite attentiveness and enthusiasm [13]. Recent studies have recommended that the interventions should be task oriented, well demonstrated and repetitive but repetitive movements are difficult to perform because the patients may lack interest and the repetition may lower the motivation level of the patients which is required for the completion of the treatment protocol [14]. This method of treatment includes ten different interventions (walking on a treadmill; standing up, walking to, and sitting down on a chair; kicking a soccer ball against the wall; walking along a balance beam; performing step-ups; walking an obstacle course; walking while carrying an object; walking at maximal speed; walking backwards; and walking up and down stairs) that are primarily intended to improve the mobility of the person affected by stroke [15]. In fact, the main concern of the stroke patients and their family is about the rehabilitation particularly the independence of the patient or in other words independence of the patient to perform the functional activities by self [16].

Material and Methods

It was a randomized control trial with sample size of 48. Sampling technique used in the study was purposive sampling technique. The randomization in the study was done by toss and coin method. Interventional group (n=24) and control group (n=24).


It has been found in the results that most of the participants 54% were males and had age between 29 to 57 years. It has also been found that most of the participants, more than 60% belong to the low socioeconomic status. The results also portrayed that almost 65% of the participants were non-smokers while only 35% were smokers. In general, smoking is regarded as one of the risk factors of stroke but this is surprising to know that most participants were non-smokers. This is because merely smoking is not a cause of stroke and it is a multifactorial disorder and smoking has little contribution to the causation of stroke.

The results depicted that the participants of the control group (n=24) have Wilcoxon test P-value >0.005 but the participants of the experimental group (n=24) have Wilcoxon test P-value < 0.005 depicting highly significant results. The Mann-Whitney test also depicted a P-Value of 0.00 that is <0.005 depicting the high significance and also there is great difference among the Mean ranks of the control and the experimental groups showing the better effects of the task oriented walking interventions.


The results of the current study portrayed that individuals receiving task oriented walking interventions have higher chances of improvement in the equal time duration for the lower extremity. The effects of task oriented walking interventions have already been tabbed by a number of researchers and it was concluded by them that this intervention is vitally helpful and more efficient in improving the balance of the patients with stroke. It was also indicated in the literature that these interventions promote the functional status effectively in comparison to the typical conventional rehabilitation programs. In order to make the patients independent after stroke and making the patient able to perform ADLs (Activities of Daily Living) with ease, the most important factor to be cared is balance. There are a number of the interventions to achieve the base of the independence but task oriented walking interventions can help in achieving this factor easily and effectively [17].

In order to know the effects of the balance on the independence of the patients, a research study “Self-efficacy in relation to impairments and activities of daily living disability in elderly patients with stroke: a prospective investigation” was conducted by Hellstrom, and colleagues. They tried to find out the effects of the as contributing factor to the independence of the stroke patients. 37 post stroke patients having age between 66 to 89 years were taken as sample and FIM (Functional Independence Measure), BBS (Berg Balance Scale) and Falls efficacy scale were used to measure the balance of the post stroke patients taken as sample. The P value was 0.002 for all the results and the P < 0.005 is depicting the high significance of the study. Thus, it was concluded that these walking interventions must be included in the rehabilitation procedure of the stroke patients [18]. Another research study “Effects of Task-Oriented Circuit Class Training on Walking Competency after Stroke” was conducted by Wevers to explore the effects of task oriented walking interventions. Studies up to March 2008 were included in this systematic review. The results favored the task oriented training for walking distance (0.43; 95% CI, 0.17 to 0.68; P<0.001), gait speed (0.35; 95% CI, 0.08 to 0.62; P=0.012), and a timed up-and-go test (0.26; 95% CI, 0.00 to 0.51; P=0.047) [19]. Another study “Task‐oriented training in rehabilitation after stroke: systematic review” was conducted by Rensink in 2009 and it was found that the task oriented walking interventions were more effective and have more significant results as compare to the traditional therapies (P<0.005) [20].


It is concluded that patients who were receiving task oriented walking interventions had considerable improvement in balance while the patients who were in control group who received the conservative rehab treatment, showed less improvement. This research study has proven that the stroke patients get better soon and they improve earlier if the therapy is concise and task oriented.
