Filter by:Pronation distortion syndrome is a postural complexity of lower extremity which primarily involves hyper pronation of feet leading to other dysfunctional movement patterns throughout the kinetic chain and gait mechanics. Excessive foot pronation is followed by internal tibial rotation and adduction of knees forming knock knees. This lower extremity distortion pattern causes a chain reaction of muscle imbalances. The objective of this study is to determine effects of 8-Weeks Systematic Corrective Exercise program on Body Posture and stability in Pronation Distortion Syndrome. This study will be a Randomized Controlled trial and will be conducted at Riphah college of rehabilitation sciences and Ibrahim medical Centre Lahore. The study will be completed within the time duration of 10 months. Convenient sampling technique will be used to collect the data. A sample size of Total 36 patients will be taken in this study. Patients will be divided into two groups. Group A will be treated with conventional treatment along with systematic corrective exercise program. Group B will be given conventional treatment only. The groups will participate in the training program one day after the pre-test, three sessions per week for two months. The diagnosis of pronation distortion will be detected by navicular drop in detectable flat feet without pain. Variables to be tested will be, functional movement screen test, navicular drop, knock knees and lordosis, and will be measured before the start of treatment and after 8 weeks of treatment. Data will be analyzed on SPSS 25.
Epiretinal membranes (ERM) consist of an abnormal growth of tissue across the retina and are present about 6% of people aged 50 and over. They can cause symptoms of distortion (straight lines appearing bent) or blurred vision. Management options include observation if asymptomatic, or surgery to peel the membrane if symptomatic. Limited data exists regarding how to identify patients who are most likely to benefit from surgery. We propose to measure the effects on distortion (using D chart), visual acuity and vision-related quality of life (using a validated vision-related quality of life questionnaire) of ERM surgery. This will allow us to investigate whether pre-operative D chart score can predict subsequent improvement in quality of life following surgery. We hope the results will help patients and VR surgeons decide whether or not to proceed with ERM surgery. The study will be a prospective case series consisting of patients with symptomatic epiretinal membranes who choose to have epiretinal membrane surgery. The study participants will get standard care with the additional administration of a quality of life questionnaire and measurement of distortion (using a D-chart) at 3 different time points (pre-op, and post-op at 26 and 52 weeks). Recruitment will be in Glasgow, with a possibility of other sites being added on at a later stage.
