AbstractThe purpose of this study was to examine the effectiveness of a 6-week core stabilization training program (CSTP) in improving dynamic balance and back-extensor endurance of horse riders; and develop a measurement tool in assessing the dynamic postural stabilization endurance for horse riders. Twelve male horse riders (age: 23.58 ± 1.93 years; height: 165.09 ± 4.60 cm; weight: 56.53 ± 4.75 kg; experience in horse racing: 1.75 ± 0.34 years) completed 12 training sessions in 6 weeks. Subjects performed the CSTP with two progressions. CSTP started with the basic consciousness activation exercises, and then eliminated visual feedback in dynamic balance task on unstable surfaces and finished with switching the center of gravity. Moderate-to-large difference was demonstrated in the Y-Balance test scores for right leg (102.81 ± 8.32 vs 106.471 ± 4.35 cm, d = 0.55, 95% CL 0.00 to 1.08) and left leg (102.04 ± 3.20 vs 106.29 ± 3.62 cm, d = 1.25, 95% CL 0.41 to 2.05) following 6 weeks CSTP. However, trivial to small differences was reported between left and right leg in pre (d = 0.12, 95% CL − 0.49 to 0.73) and post 6-week CSTP (d = 0.04, 95% CL − 0.69 to 0.78). Biering–Sørensen test (BST) shows largely greater performance after 6-week CSTP (98.3 ± 30.1 vs 131.8 ± 19.0 s, d = 1.33, 95% CL 0.54–2.09). A novel measurement, Swiss ball four-point kneeling test was shown to be correlated with the change in BST (r = 0.633).

Background: Loss of continuity of abdominal wall significantly affects the functions of protection of viscera, postural stabilization, and maintenance of intra-abdominal pressure. The newer understanding of abdominal wall reconstruction (AWR) aims at restoring abdominal wall anatomy and function, instead of simply patching the defect. We want to showcase the changing trends and results in hernia repair at a Medical Institution.Methods: This is an observational retrospective study conducted in RRMCH, Bengaluru from July 2018-2019 including all patients with ventral hernia undergoing the specified hernia repairs.Results: A total of 54 patients with ventral hernias undergoing routine hernia repairs/AWR surgeries were retrospectively analysed. The overall mean age was 46.62±12.44 year. Majority subjects were females (n=37; 68.5%), and overweight (Mean BMI=28.07±3.01/m2). 14 patients (25.92%), all males, had history of tobacco consumption. There were 38 (70.37%) primary ventral hernias and 7 recurrent hernias. Overall mean defect size was 10.2±0.4 cm. Most frequently performed was open retro rectus Hernioplasty (n=18; 33.33%), followed by open Preperitoneal Hernioplasty (n=17; 31.48%), laparoscopic intraperitoneal onlay mesh (IPOM) (n=16; 29.62%) and open transversus abdominis release (TAR) (n=3; 5.5%). On statistical analysis, it was found that Open repairs had higher post-operative pain (p=0.0005), longer hospitalization (p=0.0002) and higher incidence of surgical site events (p=0.0134) when compared to Laparoscopic repairs.Conclusion: As known already, minimally invasive techniques of hernia surgeries are shown to have acceptable outcomes when compared to radical open surgeries. Newer techniques of AWR are being employed to routine cases in larger numbers, and not just for complex reconstruction, at most centres with acceptable outcomes.

The Relationship

Dystonia is a collection of symptoms with involuntary muscle activation causing hypertonia, hyperkinetic movements, and overflow. In children, dystonia can have numerous etiologies with varying neuroanatomic distribution. The semiology of dystonia can be explained by gain-of-function failure of a feedback controller that is responsible for stabilizing posture and movement. Because postural control is maintained by a widely distributed network, many different anatomic regions may be responsible for symptoms of dystonia, although all features of dystonia can be explained by uncontrolled activation or hypersensitivity of motor cortical regions that can cause increased reflex gain, inserted postures, or sensitivity to irrelevant sensory variables. Effective treatment of dystonia in children requires an understanding of the relationship between etiology, anatomy, and the specific mechanism of failure of postural stabilization.

Bimanual Unloading

AbstractThe commentary focuses on the need for motor control modeling as a rationale for rehabilitation. We give examples in a bimanual unloading task and examine the potential consequences for recovery in patients with cerebral lesions. Hierarchical models of motor control lead to a distinction between “task optimization” and “motor optimization” and to a qualifier on Latash & Anson's “hands-off” position.
