THE IMPACT OF A ROTATING BALANCE PLATFORM ON LEG NEUROMUSCULAR ACTIVITY IN HEALTHY YOUNG ADULTS

Research Article of Internal Journal of Sports Medicine and Rehabilitation The Impact of a Rotating Balance Platform on Leg Neuromuscular Activity in Healthy Young Adults Martin G. Rosario PT, Ph.D., CSFI, ATRIC1*, Carley Bowman SPT1, Abigail Versemann SPT1, Daniel Heistand SPT1 1Physical Therapy Program, Texas Woman’s University, Dallas, Texas, USA. Balance is a functional activity that must be implemented in every type of rehabilitation for the back and lower extremities’ injury and pathology. With issues in these regions, balance is lessened, requiring exercises that enhance the patient’s stability. Purpose: To determine the impact of activities on a rotating balance platform with tracking tasks for lower limb muscle activation. Method: Twenty-five participants performed seven tasks on a balance board with a fixed middle fulcrum. For each trial, activation of the gastrocnemius and tibialis anterior muscles was recorded using surface electromyography. Upon examination of the EMG data, the following variables were quantified: time to peak muscle activation, time to decay of muscle contraction, and time of muscle contraction duration. Results: A repeated measures ANOVA revealed that TA exhibited significant modifications (P<0.001) with less time to peak, duration, and decay, whereas GA only notably compensated (P<0.001) with shorter duration and decay. Conclusion: For subjects with balance alterations due to slower nerve conduction or muscle weakness in the lower limb, we suggest incorporating activities with rotational movements on the balance board, where muscle activation is challenged due to surface and tracking activities. When endurance is prescribed, front-to-back tasks contribute to prolonged muscle activation. Balance rehabilitation should consider muscle activation timing with tracking tasks for more precise and targeted muscle execution.

OBSERVATIONS OF PERFORMANCE AND BODY COMPOSITION FOLLOWING 8-WEEKS OF PROGRESSIVE RESISTANCE TRAINING IN PARTICIPANTS WITH CEREBRAL PALSY

Research Article of Internal Journal of Sports Medicine and Rehabilitation Observations of Performance and Body Composition Following 8-weeks of Progressive Resistance Training in Participants With Cerebral Palsy Brendan Aylward1 & Jason L. Talanian2* 1Unified Health and Performance & AdaptX. Lancaster, MA 01523. 2Exercise and Sports Science Department, Fitchburg State University, Fitchburg, MA 01420. Purpose: To observe the effects of progressive resistance training on performance and body composition in participants with cerebral palsy. Methods: Four quadriplegic (3 male, 1 female) and two hemiplegic (2 female) participants (22 ± 5 yr, mean ± SD) completed moderate to high intensity resistance training 2-3 days a week for 8-weeks. Strength training programs were developed for each participant based on their physical ability. Measurements of exercise performance and body composition (InBody 270 & S10) were collected prior to and following training. Data from all participants was pooled, and samples with 5-6 subjects were analyzed using a paired t-test with significance set at p < 0.05. Results: Measurements of muscular fitness improved, including plank performance (pre: 64 ± 40, post: 95 ± 61 s, n = 6), supine sled leg press 1RM (pre: 225 ± 69, post: 378 ± 124 lb, n = 6) and bench/sled press 1RM (pre: 92 ± 54, post: 115 ± 58 lb, n = 5). There was no change in peak sprint capacity (pre: 89 ± 32, post: 96 ± 29 W, n = 5) or peak aerobic capacity (pre: 303 ± 136, post: 370 ± 246 s, n = 4). Measurements of body weight (pre: 151 ± 40, post: 151 ± 42 lb, n = 6) and skeletal muscle mass (pre: 53 ± 8, post: 54 ± 9 lb, n = 6) were unchanged following training. Conclusion: Preliminary data is encouraging that the unique and challenging strength training program employed ...

PERIPHERAL NEUROPATHY IMPACTS GAIT MOTOR COMPONENTS IN HISPANIC-LATINX LIVING WITH HIV

Research Article of Internal Journal of Sports Medicine and Rehabilitation Peripheral Neuropathy Impacts Gait Motor Components in Hispanic-Latinx living with HIV Martín G. Rosario PT, PhD, CSFI, ATRIC1*, Leah Jamison, PT, DPT1, Gabriel Gines BS, MPH, CPT, CSFI2 1Texas Woman’s University, Physical Therapy Program, Dallas Campus; Texas; 2Sara Alert, Airport Surveillance System, Department of Health, Puerto Rico. HIV can cause numerous health-related complications that can lead to disabilities and affect the quality of life. Some problems added with HIV, like peripheral neuropathy (PN), may develop additional impediments in this population. Purpose: This study investigated PN’s impact on the cardio-motor profile of Hispanic Latino living with HIV. Methods: A submaximal cardiovascular test (Ross test) was conducted to obtain the study’s cardiomotor results. Cardiomotor data were compiled from records of members enrolled at La Perla de Gran Precio Community Centre on HIV in San Juan, Puerto Rico. Results: The motor profile included the speed and inclination of the treadmill. The cardiovascular data had blood pressure and heart rate at the time Ross’s test was terminated. Two hundred and ninety-one participants were further designated as 225 in the non-PN and 66 in the PN group. Both groups average comparable amounts of CD4 counts. An ANOVA was used to determine variations in the PN group with a considerable (P < 0.05) increase in the time of HIV diagnosis and a reduction in gait velocity and treadmill inclination distinguished to counterpart. Conclusion: Hispanic Latino living with HIV and PN displayed distinctive motor gait deficiencies. Gait parameters, such as gait speed, were further impaired in those suffering from both conditions. We encourage healthcare providers to incorporate the specific cardio-motor items alluded to in this investigation to identify the process influencing gait that further alters the quality of life in those with HIV.

REPAIR OF AVULSION FRACTURE OF THE ANTERIOR SUPERIOR ILIAC SPINE BY KNOTLESS SUTURE BRIDGE: SURGICAL TECHNIQUE AND A REVIEW OF 5 CASES

Research Article of Internal Journal of Sports Medicine and Rehabilitation Repair of avulsion fracture of the anterior superior iliac spine by knotless suture bridge: Surgical technique and a review of 5 cases Tengyun Yang, Yanlin Li, Fuke Wang, Renjie He, Chuan He Department of Sports Medicine, The First Affiliated Hospital of Kunming Medical University, Kunming, Yunnan province, China, 650032 Background: Avulsion fracture of the anterior superior iliac spine (ASIS) is a rare form of apophyseal avulsion fracture of the pelvis, and there is a lack of evidence-based guidelines for the selection of treatment options. There are various surgical procedures, but there is the risk of secondary removal of internal fixator and growth disturbance caused by epiphyseal fixation. Methods: We treated 5 patients with avulsion fracture of the anterior superior iliac spine by knotless suture bridge technique who visited our hospital from 2015 to 2020.The surgical treatment results were retrospectively analyzed. Results: 5 patients with fractures were healed after the surgery, no associated complications, the mean postoperative follow-up was 29.2 months (6-60months), all patients were not reported pain symptoms (visual analogue score of 0), they don't have the limitation of daily activities, and the hip joint function recovered well, and very pleased with the results (Harris score 100 points) at the final follow-up. Conclusion: Knotless suture bridge technique is simple and effective in the repair of the avulsion fracture of anterior superior iliac spine. For such patients, this surgical technique can provide stable and reliable fixation, allow early recovery, and provide a feasible scheme for clinical practice.
