ABSTRACT
Background: Before the year 1950 treatment of myocardial Infarction patients was complete bed rest for several weeks and reduces physical activity for several months. Cardiac rehabilitation based on exercise training reduces the effects of deconditioning of bed rest. The primary purpose of this study was to determine the methods and means of prevention and treatment of coronary artery disease
Materials and Methods: This study was designed clinical trial and cross sectional study before and after intervention, the effect of our new protocol was assessed according to method of Bruce stress test. Measurement consisted of Blood Pressure and Functional Capacity, which were recorded and compared before and after intervention
Results: There was a significant increase in functional capacity according to method of Bruce stress test after ten session of training. The criterion deviation at functional capacity variable was 13.19 +/- 2.242 METS and 24.42 +/- 6.00 METS before and after 10 sessions. Respectively, this obtained METS [body oxygen survey at rest state equal to 3/5 milliliter oxygen to each kg person weight at minute] rise amount from secondary posttest to primary test [P<0.05]. There was also a significant decrease in systolic blood pressure after ten session of training. The criterion deviation and average was 121.5 +/- 8.83 and 112.00 +/- 9.18 for systolic blood pressure. This decline amounts has a meaningful variable amount given P-value <0.05
Conclusion: Cardiac rehabilitation can increase the performance of blood circulation and uptake of oxygen in body. These changes showed a significant increase in functional capacity it can also reduce resistance of blood circulation and showed a significant decrease in systolic blood pressure

Objectives: Patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome [PFPS]. Patellar taping can considerably reduce such pain and disability
This study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with PFPS [mean age 32.2+/-1.12 years] by using magnetic resonance imaging [MRI]
Methods: Thirty women with a one-year history of PFPS took part in this study. MRI was done on the participant's patellofemoral joint at 30° knee flexion with quadriceps contraction in two stages: 1st stage-immediately after kinesio taping and 2nd stage-after 10 sessions of kinesio taping. The effectiveness of the interventions was determined by measuring the patellofemoral congruence angle [PFCA], lateral patellofemoral angle [LPFA], and lateral patellar displacement [LPD] in the MRI images
Results: Statistical analysis revealed significantly reduced pain in all participants
The results showed a significant reduction in PFCA during quadriceps contraction immediately after kinesio taping, and a significant improvement was also observed in LPFA after 10 days of using kinesio taping by quadriceps contraction
Discussion: Kinesio taping plus quadriceps contraction reduced the PFCA and LPFA. Patellar taping is effective in the correction of the patellar position in contracted quadriceps. Therefore, both neuromuscular and mechanical effects of patellar taping affect the patellar position over a long period
The combination of patellar taping and exercise reduced pain and improved activity faster than either of the treatment alone
ABSTRACT
The elicited parameters from the center of pressure [COP] of patients after surgery of the anterior cruciate ligament are proper indications for estimating balance after surgery and rehabilitation. Thus, making sure about repeatability of COP parameters which can determine the knee joint after the knee reconstruction surgery is very important. This study measures repeatability rate of some COP parameters after reconstructing anterior cruciate ligament in various positions. In this study, 15 athlete men [mean age: 27 +/- 5] after 4-6 months since repair of their anterior cruciate ligament were included; they have been selected through simple non-probability sampling method. The study was conducted in biomechanics lab of Tarbiat Modares University in 2010. Assessment of balance was done with open/closed eyes, with/without foam using force platform in two sessions with 48 hours interval. The external-internal amplitude [0.86], external-internal standard deviation [0.86], phase plane [0.82] and area oscillation [0.81] were among parameters which showed the most repeatability. The average oscillation of anterior - posterior frequency [0.6] showed the lowest repeatability. A number of parameters caused by oscillation of COP show high rate of repeatability after reconstructing anterior cruciate ligament which can be used as an assessment of patients condition after reconstruction of the anterior cruciate ligament
ABSTRACT
Balance assessment plays a major role in treatment and rehabilitation of patients. Recently scientists have designed a new device with a dynamic multi-axial tilting platform to aid in joint rehabilitation and enhance proprioceptive mechanisms and postural assessment, called Biodex balance system [BBS]. Repetition of exposure to the BBS causes learning or familiarization. Therefore, it can't be sure that the changes seen in the stability index, are due to the effect of the learning or intervention. The purpose of this study was to evaluate the learning effects of test-retest postural task and to set the learning curve and test-retest reliability of dynamic standing balance using BSS. Ten healthy non-athletic persons participated in this study. The volunteers were asked to stand on BBS with two levels of difficulty on their dominant leg with open eyes. Two trials of 10 repetitions were applied at difficulty level of 4 and 8 with 30 minutes rest between each test and 30 minutes rest between two trials. Total stability index [TSI], anteroposterior [APSI] and mediolateral [MLSI] were registered. The effect of repetition of hard postural task on biodex was significantly different in trial 6 from 1-5 [P<0.05]. The effect of repetition of easy postural task on biodex was significantly different in trial of 5 from 1-4 [P<0.05]. After learning, we found no significant difference in mean stability index of test condition of each trials in reliability assessment so the intra-class correlation coefficients ranged from 0.83 to 0.92. Tests at lower stability level produced the higher ICCs [0.90-0.92]. There was a very strong correlation between total stability index and AP stability index using Pearson correlation coefficient [P<0.01, r = 88%]. The results showed that repeating a task on the BBS for five times or more have learning effects. So, while evaluating postural stability in a simple task which has more than five repetitions, learning effect should be take in to account and in difficult postural task it is sex repetitions that can have learning effects
