The Impact

Aim: To assess the impact of blood flow restriction and retro walking in knee osteoarthritis subjects. Study Design: It was a comparative study. All the participants who meet inclusion criteria gave a written consent and were allocated to Group A or Group B randomly by chit method and the pre and post test scores were derived. The scores obtained in the two groups were compared and the results were derived. Place and Duration of the Study: This study was conducted in musculoskeletal sciences division, RNPC Sawangi, Wardha, for 12 months Methodology: A total of 150 samples were chosen. Using the chit method, they were divided into two groups at random, Group A and Group B. Blood Flow Restriction Training was given to Group A, while retro walking training was given to Group B. The training lasted 15 days. After 15 days, the pain, strength, and WOMAC score were tested again. Result: Out of 150 patients 75 were placed in each group, where p=.0001. Significant increase was seen in mean of group I and II in pre ad post-test NPRS score, Quadricep and hamstrings muscle strength and WOMAC score. Analysis showed significant improvement in both the groups. Conclusion: Both the interventions included in this study, have been shown to help individuals with osteoarthritis reduce pain, enhance strength, and improve their WOMAC score. Both the interventions are easy to practice and can be easily performed by the older population. When these two interventions were compared blood flow restriction therapy was proved to be better than retro walking.

Abstract Objectives To examine the effects of moderate intensity resistance training with blood flow restriction on muscle strength and forearm girth. Methods Total of 39 students enrolled in this study were divided into three groups that is group A (control group), group B and group C. Group A performed exercise training without restrictive pressure, group B & C performed exercise training with 50 and 75 mmHg respectively. Both the outcome measures were evaluated on day 1 and day 12th with the help of digital dynamometer and measuring tape. Results Repeated measure ANOVA with Post hoc analysis was done using SPSS software version 20. The result of the study showed significant (p≤0.05) within subject improvement in muscle strength and muscle girth in all the three groups. However, significant improvement in muscle strength was found in between group analysis (p≤0.05). Conclusions The results of the study can be concluded as the partial blood flow restriction (50 mmHg) with moderate intensity resistance training resulted in greater handgrip strength than the other two groups. No difference was found in forearm girth among the three groups, however within the group difference was found.

AbstractA combination of yoga and blood flow restriction, each of which elicits marked pressor responses, may further increase blood pressure and myocardial oxygen demand. To determine the impact of a combination of yoga and blood flow restriction on hemodynamic responses, twenty young healthy participants performed 20 yoga poses with/without blood flow restriction bands placed on both legs. At baseline, there were no significant differences in any of the variables between the blood flow restriction and non-blood flow restriction conditions. Blood pressure and heart rate increased in response to the various yoga poses (p<0.01) but were not different between the blood flow restriction and non-blood flow restriction conditions. Rate-pressure products, an index of myocardial oxygen demand, increased significantly during yoga exercises with no significant differences between the two conditions. Rating of perceived exertion was not different between the conditions. Blood lactate concentration was significantly greater after performing yoga with blood flow restriction bands (p=0.007). Cardio-ankle vascular index, an index of arterial stiffness, decreased similarly after yoga exercise in both conditions while flow-mediated dilation remained unchanged. In conclusion, the use of lower body blood flow restriction bands in combination with yoga did not result in additive or synergistic hemodynamic and pressor responses.

Functional Task

Introduction: Stroke is defined as sudden onset of focal neurological deficit lasting more than 24 hours duration. There are several complications derived from these illness, including neurological disorders like gait dysfunction. Attending to this problem, some treatments have been developed, including ankle foot orthosis (AFO), knee gaiter and bobath intervention. The aim of this study is to compare the efficacy of functional task in patients affected by stroke. Material and Methods: Timed up and go (TUG) was the measurement evaluated. A total of 10 stroke patient were recruited for the study. 5 (Group A) received treatment with Functional Task Intervention with AFO knee gaiter). Group B (n=5) were treated with Bobath Intervention. The inclusion criteria were unilateral stroke with 3-6 months duration after onset, age limit 45-65 years and ability to comprehend the instructions for testing procedures. The exclusion criteria were bilateral stroke, mental dysfunction, non cooperative patients, cognitive and perceptual dysfunction, visual and auditory impairment and orthopedic disorders that impair ambulation. Results: The pretest mean score of Group A was 30.18 and the post-test mean score was 13.08. On the other hand, group B patients obtained a pre-test mean score of 31.48 and the post-test mean score was 18.04. Conclusion: The result of the present comparative study concluded that the functional task intervention with unilateral AFO and knee gaiter was more effective than Bobath intervention on stroke population.

The Impact

The aim of this study was to evaluate the impact of high-intensity strength training (ST) or low-intensity strength training with blood flow restriction (ST-BFR) on monocyte subsets, the expression of C-C chemokine receptor 5 (CCR5), and CD16 on monocytes, and tumor necrosis factor alpha (TNF-α) production of overweight men. Thirty overweight men were randomly assigned to conventional ST or ST-BFR. Both groups performed exercises of knee extension and biceps curl with equal volume (3 sessions/week) over 8 weeks, and the peripheral frequency of monocytes (CD14+CD16−, classical monocytes; CD14+CD16+, intermediate monocytes; CD14−CD16+, nonclassical monocytes), the mean fluorescence intensity (MFI) of CCR5 and CD16 on CD14+ monocytes; and the production of TNF-α by lipopolysaccharide (LPS)-stimulated cells were quantified. Eight weeks of ST increased the frequency of CD14+CD16− monocytes (p = 0.04) and reduced the percentage of CD14−CD16+ (p = 0.02) and the production of TNF-α by LPS-stimulated cells (p = 0.03). The MFI of CD16 on CD14+ monocytes decreased after the ST intervention (p = 0.02). No difference in monocyte subsets, CCR5 or CD16 expression, and TNF-α production were identified after ST-BFR intervention (p > 0.05). The adoption of ST promotes anti-inflammatory effects on monocyte subsets of overweight men, but this effect was lost when BFR was adopted. Novelty High-intensity strength training reduces the production of TNF-α and the peripheral frequency of CD16+ monocytes in overweight men. Blood flow restriction method blunts the strength training adaptations on monocyte subsets and pro-inflammatory TNF-α production in overweight men.

Cuff Width

Narrow cuffs cause less discomfort than wide cuffs immediately following elbow flexion exercise in combination with blood flow restriction, possibly due to a balling up effect of the bicep underneath the cuff. In this study, we sought to examine the impact of cuff width, sex, and pressure on perceived discomfort in the quadriceps, following knee extensions. One hundred participants completed three separate experiments. In Experiment 1, we compared participants’ discomfort at rest after using a 5 and a 12 cm cuff. In Experiment 2, we compared the discomfort from these two cuffs after four sets of exercise. In Experiment 3, we used the same exercise protocol as in Experiment 2, but we compared the discomfort between a 12 cm cuff inflated to an inappropriate pressure and a 12 cm cuff inflated to the recommended pressure. We found no sex differences in Experiments 1 and 3. In Experiment 1, the narrow cuff had higher discomfort (16 vs 12 AU). In Experiment 2, men reported higher discomfort than women, with no discomfort differences related to cuff width, though narrow cuffs were most preferred. In Experiment 3, cuffs inflated to a pressure intended for narrow cuffs were associated with higher discomfort, and participants preferred to use it less. In summary, we found no strong evidence for discomfort differences due to cuff width. There was some indication that participants preferred narrow cuffs with pressures inflated to the recommended relative pressure. Muscle shape may influence how cuff width affects discomfort.

Objective: To study the impact of isolated oligohydramnios at term on mode of delivery and perinatal outcome. Study Design: Prospective comparative study. Place and Duration of Study: Combined Military Hospital Okara, from Aug 2019 to Aug 2020. Methodology: A total of 250 patients were recruited in the study. They were divided in 2 groups. In group A there was 123 patients, with isolated oligohydramnias at term, amniotic fluid index of ≤5cm, while in group B 127 patients, with normal liquor volume were included through lottery method. Demographic parameters, Intrauterine fetal demise, mode of delivery, perinatal out comes like meconium stained amniotic fluid, low birth weight, APGAR score at 1 and 5 minutes, of two groups were compared. Results: A total of 57 (46.3%) patients in group A delivered through cesarean section and 27 (21.3%) in group B. Meconium staining of liquor was in 56 (45.5%) in group A versus 13 (10.2%) in group B. As compared to group B the patients in group A lower birth weight babies 2.6 ± 0.34 kg versus 3.0 ± 0.33 kg were delivered. Mortality in group A, intrauterine fetal demise was 4 (3.3%) and still birth was 2.3%. There were no perinatal mortality in controlled group B. Conclusion: Isolated oligohydramnias at term is not associated with adverse perinatal outcome. Umbilical cord compression, potential utero-placental insuffiency and increased incidence of meconium stained liquor possibly explains the increased perinatal morbidity. The delivery should be routinely advocated as in otherwise uncomplicated pregnancy with appropriately grown fetus.

Abstract Background:To explore the impact of seropositivity on systemic bone loss in rheumatoid arthritis (RA).Methods:This was an interim analysis of the RA registry. Clinical characteristics in the registry were documented, and bone mineral density (BMD) was measured; this was repeated 3 years later. Participants were grouped into seropositive (SPRA) and seronegative (SNRA) based on the presence or absence of rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide antibodies (ACPA). After matching (1:2) for age and sex, SNRA and SPRA were regrouped into A and B. To elucidate the impact of number of antibodies on BMD changes, the matched group was sub-divided according to the number of antibodies present (0, group I; 1, group II; 2, group III). The changes in BMD were compared for each group at baseline and 3 years later. Results:A total of 477 participants who completed a 3-year observation period were included. After matching, 312 participants were enrolled (group A, 104; group B, 208). Three years later, group B had significant bone loss in the femoral neck (FN) (p <0.001), total hip (TH) (p = 0.001), and 1st–4th lumbar vertebrae (L1–4) (p = 0.006), while group A has bone loss only at FN (p = 0.002). Groups I, II, and III included 104, 52, and 156 participants, respectively. Significant bone loss was recorded at FN (p = 0.002) in group I, FN (p <0.001) in group II, and FN (p <0.001), TH (p = 0.002), and L1–4 (p = 0.016) in group III. In terms of percent change in BMD (△BMD%), more significantly negative changes were found at TH in group B (p = 0.027) and within groups I-III (p for trend = 0.021). Logistic regression showed that seropositivity is a significant predictor of △BMD≧–5% at TH (odds ratio 1.85, 95% confidence interval 1.03-3.33, p = 0.039).Conclusions:SPRA lost more bone than SNRA after 3 years. More attention should be paid to SPRA patients, especially those with double-positive antibodies, with vigorous evaluation of BMD and fracture risk.
