    The aim of this study was to investigate the effects of chiropractic high velocity low amplitude (HVLA) sacroiliac and lumbosacral manipulation on the sprint, jump racing and jumping performance of amateur soccer players with asymptomatic dysfunction of the sacroiliac and lumbosacral joints. The 20-m sprint, 20-m jump racing and horizontal jumping distance of the soccer players analyzed in this study were measured before and after the applications. Sprint and obstacle course racing time were measured by stopwatch and video recordings. In total, 30 patients were included in the study. The participants were divided into 2 groups each with 15 members and were randomly selected. A sham manipulation was applied to the control group and chiropractic HVLA lumbosacral and sacroiliac manipulation was applied to the experimental group. The 20-m sprint time of the control group decreased from 3.49 & x202f;s to 3.46 & x202f;s. In the experimental group the 20-m sprint time decreased from 3.44 & x202f;s to 3.22 & x202f;s. The sprint values of the experimental group were statistically significantly faster than the control group (p & x202f;< 0.05). In the control group the 20-m obstacle course time decreased from 3.87 & x202f;s to 3.79 & x202f;s. In the experimental group the 20-m obstacle course racing time decreased from 3.75 to 3.60 & x202f;s. There was no statistically significant difference between the two groups (p & x202f;> 0.05). In the control group the horizontal jump distance increased from 266.93 & x202f;cm to 268.80 & x202f;cm. This score increased from 261.13 & x202f;cm to 267.80 & x202f;cm in the experimental group. Comparison of the horizontal jumping distance revealed that the experimental group had a statistically significant better performance than the control group (p & x202f;< 0.05).

    BACKGROUND: Deterioration associated with aging in the erect posture and balance to change the location of the center increased the rate of fall in older age is one of the reasons. Loss of muscle strength is one of the major factors affecting the posture. In this prospective, randomized and controlled study, it was aimed to investigate the effectiveness of strengthening postural muscles through electrostimulation or by applying biofeedback exercises with static posturography in patients aged 60 years and over with balance disorder. METHODS: Patients aged between 60-80 years, who applied to Istanbul Faculty of Medicine Physical Medicine and Rehabilitation Department outpatient clinic and had been diagnosed with balance disorder using the Timed Up and Go (TUG) test, were included. 250 patients were screened, from them 67 patients were enrolled and 57 of them completed the study. Patients were randomized to three groups. The patients in Tetrax (R) group (TG) group (n: 18) participated in a 15-minute exercise with Tetrax (R) which consisted of 15 minutes exercise session 3 times weekly for 4 weeks. The patients in EG group (n: 19) received an electrostimulation program of postural muscles of 40 minutes per session 3 times weekly for 4 weeks. Patients in the control group (n: 20) did 6-week balance exercises which were performed by other groups as well. 48 out of 57 patients attended the 6th-month control. As determinants of balance status Timed Up and Go Test (TUG), Berg Balance Scale (BBS) and Fall Index measured by Tetrax (R) were calculated at baseline, 1-month and 6-month follw up assesments. The patient's quality of life was assesed by Turkish version of World Health Organisation Quality of Life Questionnaire in Older Adults (WHOQOL-OLD. TR) at baseline and 6-month follow up assesments. RESULTS: TUG values in both EG and TG decreased significantly between baseline assesment and 1-month (mean differences for TG: -4,00 +/- 1,309 and EG -2,588 +/- 1,839 p = 0,002 for the each of groups) and baseline assesment and 6-month (mean differences for TG: -2,933 +/- 1,223 and EG -2,058 +/- 1,477 p = 0,003 for the each of groups). A significant increase was determined in BBS values between baseline and 1-month (mean differences for TG: 4.000 +/- 2,360 and EG: 3,529 +/- 2,672 p = 0,031 for the each of groups). Fall Index (FI) measured by Tetrax (R) decreased between baseline assesment and 1-month (p = 0,185), and 6-month (p = 0,086) respectively, also between 1-month and 6-month follow up assesments (p = 0,627), but all of them were not significant changes. In all three groups the quality of life (p = 0,951) improved. Exercises conducted with Tetrax (R) were more effective than electrostimulation of postural muscles in increasing TUG values and decreasing BBS values. CONCLUSIONS: Even though applying electrostimulation to postural muscles affected patients positively compared to pretreatment, exercises performed with Tetrax (R) were more effective than the electrostimulation protocol to postural muscles in reducing balance disorder and this well-being continued even in the 6th month.
