Background –The Transverse abdominis with its direct attachments to lumber vertebrae through thoracolumber fascia contributes as a local stabilizer of spine which have meaningful role for spinal stability. Transverse abdominis(TrA) activation is vital component in rehabilition of patients with Low back pain. The Pressure Biofeedback Unit (PBU) is a device designed to teach and measure Transverses abdominis activation by Abdominal draw-in maneuver which is often used by clinicians. Methods – 60 healthy male and female subjects were selected for study. The abdominal draw-in test was performed with the subject in a prone lying position, and the Pressure Biofeedback Unit (Chattanooga Stabilizer ) was utilized to evaluate the ability of the subject to perform this abdominal isolation test. For intrarater reliability, the examiner carried out the test twice at the interval of 2 days. For interrater reliability, 2 examiners did the test one after the other on the same day. Results – Intraclass Correlation Coefficient (ICC) were calculated to determine interrater and intrarater reliability.ICC value for inter-rater reliability is 0.87 with 95% confidence interval (0.78-0.92). ICC value for intra-rater reliability is 0.86 with 95% confidence interval (0.79 – 0.93). Conclusion - Pressure Biofeedback Unit shows good to excellent inter-rater and intra-rater reliability.

Background: Geriatric population is defined as population aged 60 years and above. Currently, India has the second largest aged population in the world. Due to aging processes, diseases and inactivity, balance often is impaired among older people. The impairment can lead to dramatic consequences such as dependency in ADL, administration to nursing homes, falls and fractures. Complementary and alternative therapies, such as yoga, are theorized to be more therapeutic than traditional exercise because of the mind-body component. Yoga requires the stretching of major muscle groups to improve physical strength and flexibility. Yoga, with its gentle movements, can address known fall risk factors like poor balance, impaired mobility, reduced strength and flexibility and focus on increased awareness and proprioception, resulting in improved balance in older adult. Objective: The objective of the study was to see the effects of yoga on balance in geriatric population. Materials and Methodology: 60 healthy elderly volunteers aged 60 years and above both male and female were selected from different old age homes of ahmedabad city and randomly divided in to 2 groups. Group A: experimental and group B: control. General characteristics (age, gender) were collected. Experimental group performed yoga for 6 weeks, six days in a week for 45 to 50 minutes; including 5-10 minutes of warm up focused on slow dynamic muscle movements with shoulder/arm circling, neck rolling. This was followed by 25-30 minutes of asanas consisting of following poses: pavanmuktasana, sputa matsyendrasana, setu bandha sarvangasana, bhujangasana, ardh-paschimottasana, paschimottasana, parvatasana, marjarasana, trikonasana, virbhadrasana, uttkatasana, and vrikshasana. Session was ended with 5-10 min of relaxation with savasana. Subjects of control group were asked to report after six weeks. BBS and TUG scores were taken as pre and post data. Result: The result shows that there is statistically significant improvement in balance after 6 week of yoga practice in elderly individuals compared to a control group at 5% significance level. Conclusion: Yogasana is effective in improving balance in elderly individuals compared to control group. It can be applied clinically for improving balance in geriatric population.

Background: Hand grip strength is of great significant parameter in evaluation of hand function and it is most reliable clinical assessment tool of human strength. It is very useful in various professions where people must work with their hand, like physiotherapy. The core serves at the center of functional kinetic chain in alternative medicine world; the core has been referred to as the “powerhouse”, the foundation or engine of all limb movements. So the purpose of this study is to find out correlation between hand grip strength and core muscle activation in physical therapists of age group 18 to 25. Methods: Two hundred physical therapists volunteered to participate in this study were assessed for height, weight, BMI, the hand grip strength of the dominant hand and the non-dominant hand and core muscle activation. The hand grip strength was assessed with Jamar dynamometer and the core muscle activation was assessed with Pressure Biofeedback Unit. Results: Pearson’s correlation coefficient was used. The results of this study shows that there was weak positive correlation(r=0.42) between the hand grip strength of dominant hand and non-dominant hand with core muscle activation. Conclusion: This study shows weak correlation between the hand grip strength with core muscle activation. Key words: Hand grip strength, Hand dynamometer, Core muscle strength, Pressure Biofeedback Unit.
