RESUMO
Background and objective Balance and trunk control are major concerns among older adults during stroke rehabilitation. Loss of proprioception in the affected limb has a greater influence on motor learning and reeducation during balance training. Available studies stress the relevance of strength and functional training in regaining balance and trunk control. Proprioception training, in addition to available rehabilitation, can optimize the balance among this population. Our study aimed to find out the effects of proprioceptive training on balance and trunk control among the chronic stroke population. Methodology Out of 45 subjects enrolled at the Indian Head Injury Foundation, New Delhi, India, 30 subjects were selected based on selection criteria and randomized into two groups using the chit method, with 15 subjects in each group. The control group received conventional training, which included a range of motion, stretching, and strengthening exercises, while the intervention group received additional proprioceptive training five days per week for four consecutive weeks. Subjects were assessed on the Berg Balance Scale and Trunk Control Test for balance and trunk control on day one and after four weeks. A paired t-test was used to analyze the difference within the groups, and unpaired t-tests were used between the groups, keeping p < 0.05 as a significance level. Results After four weeks of intervention, statistically significant improvements were seen in the balance and trunk control groups, with p < 0.05 in both groups. However, a significant improvement in balance was observed in the experimental group when compared across groups (p = 0.001), whereas no statistically significant improvement in trunk control was found (p = 0.061). Conclusion We conclude that proprioceptive training and conventional physiotherapy both help to improve balance. Proprioceptive training is better for improving balance, but it has no significant effects on trunk control. It is likely that an extended intervention time or a different form of intervention may be required to achieve substantial gains in these areas. Future research might look at other outcome measures or the impacts of other types of therapies to see which ones are most helpful at increasing trunk control.
RESUMO
Introduction Maintaining continence and providing support to the abdominal contents and sexual functioning are among the primary roles of pelvic floor muscles. The pelvic floor muscles work in synergy with the abdominal muscle to perform these functions. Abdominal muscle activation in the sagittal plane is influenced by the lumbar spine posture. As pelvic floor dysfunction is common among post-menopausal women, this study aims to find out the relationship between lumbar posture and electromyographic (EMG) activity of the rectus abdominis (RA) muscle and vaginal pressure (VP) as a functioning of the pelvic floor muscles among osteoporotic post-menopausal females. Methods A total of 78 osteoporotic post-menopausal women were recruited and allocated into three groups depending on lumbar lordotic angle, namely normal lordosis (n=26) hyperlordosis (n=26), and hypolordosis (n=26). All the subjects were recorded for RA EMG activity and VP for pelvic floor function in the quiet standing (QS) position, and voluntary dynamic tasks such as maximal coughing (MC) and Valsalva maneuver (VM). Data were analyzed using one-way analysis of variance (ANOVA) and post hoc analysis. A 5% probability level was considered statistically significant, i.e., p<0.05. Results The results showed a significant reduction in the RA activity and VP during the dynamic tasks (MC and VM) among subjects with the altered lumbar lordotic angle (p<0.05). The reduction in RA activity and VP was found to be significantly higher (p<0.05) in subjects with hyperlordotic lumbar spine than in those with hypolordotic lumbar spine as compared to normal lordosis during QS, MC, and VM. Conclusion We conclude that osteoporotic post-menopausal women with different lumbar lordotic angle show variations in RA activity and pressure generated by the vagina as a function of the pelvic floor during voluntary dynamic tasks.
