Background: Stroke often leads to significant impairment of trunk and upper extremity functions, which is associated with decreased quality of life and functional performance in all domains. Trunk stability and control is considered to be a prerequisite for upper extremity function in stroke survivors. Therefore, it is important to evaluate the relationship between trunk impairment and upper extremity function in stroke survivors which may help in improving their ADL’s by giving proper treatment. Methods: 20 chronic stroke survivors with age group between 40 – 80 years were included in this study. Trunk impairment, upper extremity function and activities of daily living of all the participants were determined using trunk impairment scale, Chedoke arm and hand activity inventory scale (version 8) and functional independence measure – motor scoring scale. Results: Using Karl Pearson’s Correlation coefficient, moderate positive correlation was observed between TIS and CAHAI-8. Strong positive correlation was noted between TIS and FIM-M, whereas, moderate positive correlation was noted between CAHAI-8 and FIM-M which was found to be highly statistically significant. Conclusion: Our study concludes that, a moderate positive correlation exists between trunk impairment and upper extremity function in chronic stroke survivors. The study also reveals that, both trunk impairment and upper extremity function has strong and moderate correlation on their activities of daily living.

Background: The evaluation of causes and consequences of non-specific low back pain along with related symptoms are critical in terms of planning the treatments of patients. Muscular imbalance can cause postural impairment and reduced functional performance in individuals with low back pain. Therefore, determining the role of trunk muscular endurance in individuals with non-specific low back pain and its reflections on dynamic postural control and functional performance are very important for both patients and physiotherapists in terms of establishing an effective treatment program. Methodology: 39 participants with non-specific LBP aged between 18-50 years were included in this study. Biering-Sorensen test, Y-balance test and 5 min walk test were the outcome measures used to evaluate trunk extensor endurance, dynamic postural control and functional performance. Result: Using Karl Pearson's Correlation coefficient, strong positive correlation was observed between trunk extensor endurance and 5-minute walk test, and between trunk extensor endurance and Y-balance test, which was found to be highly statistically significant. Conclusion:This study concludes that there is a strong positive correlation exist between trunk extensor endurance and dynamic postural control, and also between trunk extensor endurance and functional performance in patients with non-specific low back pain.
