Item Baseline Range of Motion of the Lower Limb in Parkinsonian Gait is Consistent Among Treatment and Control Groups(2021) Terrell, Zachary; Moudy, Sarah; Hensel, Kendi; Patterson, RitaPurpose: Tens of thousands of people are diagnosed with Parkinson's disease (PD) each year, making PD the second most common neurodegenerative disorder. The overarching goal for this project is to examine the efficacy of osteopathic manipulative treatment (OMT), and osteopathic cranial manipulative medicine (OCMM) particularly, in improving Parkinsonian gait. However, the purpose of this study is to serve as a preliminary analysis and comparison of the baseline joint angle data across experimental PD groups. We hypothesize that no significant differences will be found in the baseline range of motion (ROM) of each joint across randomly-assigned treatment and sham PD groups. Methods: An 18-camera motion analysis system was used in conjunction with 54 reflective markers on the body to capture three-dimensional position data in a short treadmill walking trial before the application of a whole-body (including OCMM techniques), neck-down, or sham OMT protocol. Ankle, knee, and hip joint ROM in the sagittal plane during the gait cycle was compared across treatment and control groups. Results: Baseline ROM at the hip, knee, and ankle joints across experimental groups (two treatment groups and one sham group) was comparable within one standard deviation of the mean of each group. 5.4, 11.4, and 5.7-degree variations in mean ROM were found between groups at the hip, knee, and ankle respectively. Conclusion: This preliminary analysis shows that experimental groups are not likely to significantly differ in baseline range of motion. These results validate the randomization of participants in our research design.Item Compensatory tibial torsion as a component of turnout in professional ballet dancers(2021) Mirochnitchenko, Alissa; Surve, Sajid; Patterson, RitaPurpose Classical ballet emphasizes external rotation (ER) of the hip joint as the primary mechanism of turnout, with ideal turnout being 90 degrees in each leg. Due to anatomical constraints, few dancers are able to achieve this ideal without compensating elsewhere in the kinetic chain. One mechanism of compensation for inadequate hip ER is tibial torsion. The purpose of this study is to determine the contribution of tibial torsion to turnout in a sample of professional ballet dancers. Methods The study sample consisted of five male and five female professional ballet dancers. Using motion capture technology, each dancer was filmed completing barre exercises at three times during the performance season. Rotational movement at the femoroacetabular, tibiofemoral and tibiotalar joints was approximated using motion markers. Results While the majority of external rotation during all movements originated at the femoroacetabular joint, females demonstrated 12-14 degrees of turnout originating at the tibiofemoral joint, and males demonstrated 15-17 degrees. Across all movements, females demonstrated more turnout originating at the hip joint than males. Conclusions According to classical ballet aesthetics, a turnout of 90 degrees is expected in each leg, with only 5 degrees of total turnout originating from each knee joint. The degrees of turnout originating from the knee in this sample exceed these values. Furthermore, the use of non-invasive motion-based testing such as motion capture allows for the creation of a three-dimensional model which may be used for performance tracking and injury prevention in dancers.Item Movement Patterns in Dancers: analysis of pelvis and hip movement in elite ballerinas(2021) Mirochnitchenko, Alissa; Surve, Sajid; Patterson, RitaPurpose: Ballet dancers place extreme demands on their bodies throughout their careers. To reduce injury risk and prolong a ballet dancer's career, attention must be paid to correct positioning and joint biomechanics. The specific aim of the Movement Patters in Dancers study was to observe changes in posture and movement throughout the ballet performance season. Methods: The study sample consisted of five male and five female professional ballet dancers. Using motion capture technology, each dancer was filmed completing barre exercises at three different times during the performance season. Movement of the pelvis was analyzed in three planes of motion: medial/lateral, flexion/extension, and torsion about a longitudinal axis. Additionally, the hip angle, defined as the angle between the femurs, was calculated. Results: Dancers demonstrated consistency in pelvis movement in all planes throughout the performance season. The degrees of motion observed in each plane varied with the direction in which the movement was performed (side, front, and back). No significant changes were observed between visits. Hip angle varied between the left and right side in both male and female dancers, with female dancers demonstrating larger differences between legs. Conclusions: The pelvic stability demonstrated in this study was reflective of dancers' level of proficiency and training. The difference in hip angle between the left and right legs could be explained by dancers having a dominant leg. Further analyses of the collected data can contribute towards creating a model to assess dancers at different levels of training and assist dancers recovering from injury.Item Whole Body OMT as a Treatment for Postural Instability in Parkinson's Patients(2021) Patterson, Rita; Gibson, Keenan; Hensel, KendiBackground: Osteopathic Manipulation Treatment (OMT) is a manual therapy directed at relieving somatic dysfunction in patients. OMT has shown in previous studies to improve postural stability in specific patient groups and may be a treatment option for movement disorders. Parkinson's Disease (PD) is one such movement disorder where falls are a major cause of patient morbidity. However, an OMT protocol for PD has not been established. Methods: We performed a randomized control trial on PD and healthy patients to determine the efficacy of an OMT protocol. Group A received OMT treatment of the full body including cranial manipulation, Group B received OMT treatment from the neck down, and Group C received a "sham" OMT treatment. Pre- and Post-treatment clinical measurements of postural stability consisted of Functional Reach (FR) and Timed Up and Go (TUG) tests. Biomechanical measurements of quiet standing sway were observed using a 12 Camera motion analysis system and a force plate. Results: Patients showed improvement in the times to complete the TUG test across all three treatment groups with the greatest improvement (-0.52 s) demonstrated by Group A (p < 0.05). FR results showed improvement in all three treatment groups with the greatest change (+3.5cm) occurring in Group B (p< 0.05). Biomechanical data showed an increase in the RMS in the x and z directions following treatment (p >0.05). Conclusions: Full body OMT that includes cranial techniques may improve postural stability and be considered as part of a multi-therapy management of PD.
