Abstract
PURPOSE Evaluation the effects of dry needling on sonographic, biomechanical and functional parameters of spastic upper extremity muscles. METHODS Twenty-four patients (35-65 years) with spastic hand were randomly allocated into two equal groups: intervention and sham-controlled groups. The treatment protocol was 12-sessions neurorehabilitation for both groups and 4-sessions dry needling or sham-needling for the intervention group and sham-controlled group respectively on wrist and fingers flexor muscles. The outcomes were muscle thickness, spasticity, upper extremity motor function, hand dexterity and reflex torque which were assessed before, after the 12th session, and after one-month follow-up by a blinded assessor. RESULTS The analysis showed that there was a significant reduction in muscle thickness, spasticity and reflex torque and a significant increment in motor function and dexterity in both groups after treatment (p < 0.01). However, these changes were significantly higher in the intervention group (p < 0.01) except for spasticity. Moreover, a significant improvement was seen in all outcomes measured one-month after the end of the treatment in the intervention group (p < 0.01). CONCLUSIONS Dry needling plus neurorehabilitation could decrease muscle thickness, spasticity and reflex torque and improve upper-extremity motor performance and dexterity in chronic stroke patients. These changes were lasted one-month after treatment.Trial Registration Number: IRCT20200904048609N1IMPLICATION FOR REHABILITATIONUpper extremity spasticity is one of the stroke consequences which interfere with motor function and dexterity of patient hand in activity of daily livingApplying the dry needling accompanied with neurorehabilitation program in post-stroke patients with muscle spasticity can reduce the muscle thickness, spasticity and reflex torque and improve upper extremity functions.

Abstract
INTRODUCTION AND HYPOTHESIS Patients with chronic functional constipation have some problems such as weakness of pelvic floor muscles, and a lack of coordination of pelvic floor and abdominal muscles has been seen. The goal of this study was to investigate the lumbar proprioception and the core muscle recruitment pattern. METHODS The study type is a cross-sectional case-control study. There were 30 participants (case, n = 15, and control, n = 15). Electromyography of the core muscles was recorded while the subjects were getting up from the chair accompanied by lifting a weight, to check the pattern of muscle recruitment. Moreover, the lumbar proprioception was evaluated by an isokinetic device in both groups. The study was analyzed using independent t test and Mann-Whitney U test, and a nonparametric Friedman test was performed followed by Bonferroni pairwise comparison. RESULTS The comparison of muscle activity delay between the two groups showed that there was a significant difference between the two groups regarding the abdominal muscles, anal sphincter, and erector spinae (p < 0.05). However, there was no significant difference in the rectus femoris and gluteal muscles between the two groups (p > 0.05). Moreover, the proprioception of the lumbar region showed a significant difference (p < 0.05) between the two groups. CONCLUSIONS The results of this study demonstrated that the lumbar proprioception sense was reduced in the case group. This result can be justified, based on the problems in constipation (lack of coordination of muscles, weakness of pelvic floor muscles). The coordination of core muscles changed in patients with chronic functional constipation during a functional task.

Abstract
Background We evaluated the effects of combined complex decongestive therapy (CDT) with electrotherapy modalities (ultrasound and faradic currents) in patients with breast cancer-related lymphedema (BCRL), investigating upper extremity circumference, volume, pain, and functional disability. Methods Thirty-nine patients with unilateral BCRL were randomly allocated to three groups (n = 13) as the following: The control group received CDT, the ultrasound group received CDT and therapeutic ultrasound, and the faradic group received CDT and faradic current. All the participants underwent treatment for 10 sessions. The outcomes including volume, circumference (measured at five points), pain intensity, and functional disability of the affected upper extremity were evaluated at baseline and after the treatment. Results Following the treatment, an improvement was noted in lymphedema volume, pain, and functional disability in all the three groups and there was a significant difference between the groups (P < 0.05). However, changes in limb circumference at the end of the treatment were not significantly different among the three groups in any sites (P > 0.05). Conclusion The combination of electrotherapy modalities, faradic current or ultrasound, with CDT can result in a greater reduction in lymphedema volume, pain, and functional disability in patients with BCRL.

Quantitative Electroencephalography and Surface Electromyography Correlations upon Predictable and Unpredictable Perturbation in Older Adults. J Biomed Phys Eng 2022; 12:257-266. [PMID: 35698538 PMCID: PMC9175129 DOI: 10.31661/jbpe.v0i0.2004-1098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Accepted: 07/15/2020] [Indexed: 06/15/2023]
Abstract
BACKGROUND Quantitative Electroencephalography (qEEG) is a non-invasive method used to quantify electrical activity over the cortex. QEEG provides an accurate temporal resolution of the brain activity, making it a useful tool for assessing cortical function during challenging tasks. OBJECTIVE This study aimed to investigate postural adjustments in older adults in response to an external perturbation. MATERIAL AND METHODS In this observational study, nineteen healthy older adults were involved. A 32-channel qEEG was employed to track alterations in beta power on the electrodes over the two sensory-motor areas. Integrated electromyographic activity (IntEMG) of the leg muscles was evaluated in response to perturbations under predictable and unpredictable conditions. RESULTS The results indicated higher beta power during late-phase in the Cz electrode in both conditions. IntEMG was significantly greater in the tibialis anterior muscle during both conditions in the CPA epoch. In predictable condition, a positive correlation was found between the beta power over C4 (r = 0.560, p = 0.013) and C3 (r = 0.458, p = 0.048) electrodes and tibialis anterior muscle amplitude, and between beta power in C4 and gastrocnemius amplitude (r = 0.525, p = 0.021). In unpredictable condition, there was a positive correlation between beta power over the C4 and the tibialis anterior amplitude (r = 0.580, p = 0.009) and also it over the C3 and the tibialis anterior amplitude (r = 0.452, p = 0.049). CONCLUSION Our findings demonstrate that sensorimotor processing occurs in the brain during response to perturbation. Furthermore, cortical activity appeared to be greatest during the recruitment of the muscles upon late-phase in older adults.

Abstract
Background Virtual reality training (VRT) is a new method for the rehabilitation of musculoskeletal impairments. However, the clinical and central effects of VRT have not been investigated in patients with patellofemoral pain (PFP). To comprehensively assess the effects of VRT on clinical indices and brain function, we used a randomized clinical trial based on clinical and brain mapping assessment. Methods Twenty-six women with PFP for more than 6 months were randomly allocated to 2 groups: intervention and control. The intervention consisted of lifestyle education + 8 weeks VRT, in 24 sessions each lasting 40 min of training, whereas the control group just received lifestyle education. The balance was the primary outcome and was measured by the modified star excursion balance test. Secondary outcomes included pain, function, quality of life, and brain function which were assessed by visual analogue scale, step down test and Kujala questionnaire, SF-36, and EEG, respectively. Pre-intervention, post-intervention and follow-up (1 month after the end of the intervention) measurements were taken for all outcome measures except EEG, which was evaluated only at pre-intervention and post-intervention). Analyses of variance was used to compare the clinical outcomes between the two groups. The independent t-test also was used for between group EEG analyses. Results Balance score (P < 0.001), function (P < 0.001), and quality of life (P = 0.001) improved significantly at post-intervention and 1 month follow-up in the VRT group compared with the control group. VRT group showed a significantly decreased pain score (P = 0.004). Alpha (P < 0.05) and theta (P = 0.01) power activity also increased in the brain of the VRT group. Conclusion This study demonstrated that long term VRT was capable of improving both clinical impairments and brain function in patients with PFP. Therefore, therapists and clinicians can use this method as a more holistic approach in the rehabilitation of PFP. Trial registration IRCT, IRCT20090831002391N40. Registered 23 / 10 / 2019.

Abstract
BACKGROUND There is no consensus regarding the positive effect of kinesiotaping (KT) on spasticity. All previous studies have measured spasticity by Modified Ashworth Scale (MAS) scale which is a subjective clinical assessment. OBJECTIVE To investigate the effect of inhibitory KT on the spasticity of plantar flexor muscles using both Hoffmann-reflex (H-reflex) and MAS scale. H-reflex is a neurophysiological technique that objectively evaluates spasticity by reflecting the excitability of motor neurons. METHODS Thirty patients were randomly assigned into inhibitory KT (n = 15) and control (n = 15) groups. The inhibitory KT group received KT from insertion to the origin of gastrocsoleus muscle . Spasticity was assessed at baseline and 30 min and 48 h after taping by H-reflex and MAS scale. The control group received no taping and spasticity was assessed at baseline and 30 min and 48 h after the baseline. RESULT There was a significant time × group effect for the maximal peak-to-peak amplitude of the Hmax/Mmax ratio (p = .007), indicating that Hmax/Mmax ratio decreased significantly after 48 h in the inhibitory KT in comparison with the baseline (P = .001) and 30 min after-intervention (p = .002); meanwhile, it did not change significantly in the control group (P > .05). However, none of the groups showed a statistically significant change in MAS score (P > .05). CONCLUSIONS Application of inhibitory KT was found to be able to reduce the Hmax/Mmax ratio in patients with stroke. As a result, inhibitory KT could have beneficial effects on spasticity.

Abstract
The code of ethical conduct for physiotherapy services must be compatible with the local culture. The ethical guidelines proposed here were developed through a literature review, focus group discussions, and finally a modified Delphi technique to achieve consensus after the data were analysed. At first, the collection of different ethical codes yielded 132 items. In the second stage, repetitive items were discarded, some new items were added, and the various codes were categorised into three domains. Overall, 175 items were considered in the Delphi stage. Subsequently, the items were reduced to 134 in total - 59 in the treatment domain, 41 in research, and 34 in the education domain. The resulting code of ethics will support patients, researchers, students, and teachers in the field of physical therapy with sensitivity to current Iranian legislation and culture.

Abstract
BACKGROUND Crouch gait pattern is a common gait pattern in children with diplegic cerebral palsy with excessive knee flexion throughout stance phase. Few studies have grouped this pattern of gait and usually have examined only the features of gait in the sagittal plane and mostly lower extremities without considering pelvis and trunk behavior. Studies usually categorize the gait pattern according to important variables from the researcher's point of view. Sparse K-means is high dimensional clustering methods that perform clustering and variable selection simultaneously even with low sample size and large number of variables. Our aim was to define existing clusters of crouch gait pattern in children with spastic diplegic cerebral palsy. METHODS Cluster analysis was applied on the lower extremity, pelvis and trunk gait kinematics data of 64 limbs of children with crouch gait pattern and 64 limbs of typically developing children. Eighty-nine kinematic variables were used as input variables for clustering. FINDINGS Four clusters of crouch gait pattern were defined. Sparse K-means identified influential variables and identified the knee and hip flexion as a major factor in clustering. Kinematic of the trunk, pelvis and ankle was determined in each cluster. Trunk and pelvis kinematic features were strongly correlated with the knee and hip joint flexion severity. INTERPRETATION Obtained clusters were confirmed observationally. With increasing knee flexion, the kinematic of the trunk and pelvis were further away from the patterns of typically developing individuals. The clusters ranking appear to be reasonable based on the crouch severity.

Abstract
Background Patellofemoral pain (PFP) is the most prevalent orthopedic problem in active young adults. Due to its multifactorial etiology, a variety of therapeutic measures have been adopted to treat PFP, including exercise therapy, electrotherapy, and manual therapy. It has also been suggested that whole body vibration (WBV) can improve neuromuscular function in persons with knee problems. The aim of the present study was to evaluate the effects of adding WBV to routine exercise programs on flexibility, vertical jump height, agility and pain in athletes with PFP. Methods Twenty-four male athletes with PFP were randomized into two groups of WBV + exercise (n = 12) or exercise only (n = 12). Participants received their interventions during 4 consecutive weeks (12 sessions). Pain intensity, flexibility and agility were assessed respectively as score on a numerical rating scale, the sit-and-reach test, and a modified T-test, and vertical jump height was measured to the nearest centimeter. The tests were done before and after the interventions, and the results were compared between the two groups. Independent t-tests and paired t-tests were used for between- and within-group comparisons, respectively. Results After the interventions, all variables for vertical jump height, flexibility, agility and pain intensity improved significantly in both groups (p < 0.05). The flexibility test showed significantly greater improvement in the WBV + exercise group (p<0.001), whereas for vertical jump height, agility and pain intensity, there were no statistically significant differences between groups (p>0.05). Conclusions The present findings showed that exercise therapy with and without WBV can significantly decrease pain and increase agility, vertical jump height and flexibility in athletes with PFP. Adding WBV to routine exercise therapy, however, can augment the effects of the latter on flexibility. Trial registration IRCT, IRCT20090831002391N39.

Abstract
OBJECTIVES To investigate whether the positional release technique (PRT) affects central sensitization in patients with chronic tension-type headache (TTH). DESIGN Randomized controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. SETTING Two university neurology clinics. PARTICIPANTS Patients (N=32) with TTH and myofascial trigger points (MTrP) in their cervical muscles. INTERVENTIONS Patients in the PRT group received 10 treatment sessions for each of their MTrPs over the course of 5 weeks. All participants could use ibuprofen 200 mg for their headaches during the study. MAIN OUTCOME MEASURES The primary outcome measure was brain metabolite profile. The secondary outcome measures were headache frequency and intensity, McGill score, and pressure pain threshold (PPT), which were evaluated in each participant during 5 weeks with proton magnetic resonance spectroscopy, patients' self-reports, the McGill Pain Questionnaire, and a pressure algometer. RESULTS Analysis of the data from 26 patients showed that headache frequency (P=.001), headache intensity (P=.002), McGill score (P=.003), and local PPT (P=.003) changed significantly after PRT. The myo-inositol/creatine concentration ratio in the somatosensory cortex (P=.041) decreased significantly in the control group. Furthermore, there were significant differences between groups in headache frequency (P<.001), headache intensity (P<.001), McGill score (P<.001), local PPT (P=.004), distal PPT (P=.041), and glutamate-glutamine/creatine concentration ratio in the thalamus (P=.014). CONCLUSIONS These findings indicate that PRT did not affect central sensitization in patients with TTH despite the improvement in clinical symptoms.

Abstract
BACKGROUND Electromyography (EMG) signal processing and Muscle Onset Latency (MOL) are widely used in rehabilitation sciences and nerve conduction studies. The majority of existing software packages provided for estimating MOL via analyzing EMG signal are computerized, desktop based and not portable; therefore, experiments and signal analyzes using them should be completed locally. Moreover, a desktop or laptop is required to complete experiments using these packages, which costs. OBJECTIVE Develop a non-expensive and portable Android application (app) for estimating MOL via analyzing surface EMG. MATERIAL AND METHODS A multi-layer architecture model was designed for implementing the MOL estimation app. Several Android-based algorithms for analyzing a recorded EMG signal and estimating MOL was implemented. A graphical user interface (GUI) that simplifies analyzing a given EMG signal using the presented app was developed too. RESULTS Evaluation results of the developed app using 10 EMG signals showed promising performance; the MOL values estimated using the presented app are statistically equal to those estimated using a commercial Windows-based surface EMG analysis software (MegaWin 3.0). For the majority of cases relative error <10%. MOL values estimated by these two systems are linearly related, the correlation coefficient value ~ 0.93. These evaluations revealed that the presented app performed as well as MegaWin 3.0 software in estimating MOL. CONCLUSION Recent advances in smart portable devices such as mobile phones have shown the great capability of facilitating and decreasing the cost of analyzing biomedical signals, particularly in academic environments. Here, we developed an Android app for estimating MOL via analyzing the surface EMG signal. Performance is promising to use the app for teaching or research purposes.

Abstract
BACKGROUND The maintenance of postural control is a key component in dynamic physical activity, especially during muscle fatigue and against external forces. Despite many studies in this field, there is no consensus regarding the effects of plantar flexor muscles fatigue on postural control during different postural tasks. OBJECTIVE To evaluate the effects of plantar flexor muscles fatigue on postural control during quiet stance and external perturbation in healthy subjects. MATERIAL AND METHODS Twenty four healthy individuals (20-35 years) participated this interventional study. The foot center of pressure data was measured using a single force platform, and then the postural control parameters, including the center of pressure displacement and velocity in the anterior-posterior and medial-lateral direction and also path length calculated under two conditions; quiet and perturbed stance, before and after plantar flexor muscles fatigue. RESULTS The statistical analysis demonstrated that mean displacement and velocity of the center of pressure in the anterior-posterior direction and also path length increased after the fatigue protocol in the perturbed condition. However, fatigue had no significant effects on postural control parameters in the quiet standing condition. CONCLUSION These results indicated that the effects of muscle fatigue on postural control depend on the difficulty of the task and the relevance of proprioceptive information. The postural control system appears to use distinct control strategies in different situations such as quiet and perturbed stance conditions, and these strategies may be differentially altered by fatigue. In conclusion, due to the potential risk of loss of balance, it is important to take the role of plantar flexor muscle fatigue into account during more difficult postural tasks.

Abstract
BACKGROUND This study aims to evaluate the effect of exercise training on heart rate variability (HRV) and to determine the correlation between parameters of HRV and the ejection fraction in patients with heart failure after percutaneous coronary intervention. MATERIAL AND METHODS Fifty patients with left ventricular ejection fraction ≤ 40% undergone percutaneous coronary intervention were randomly allocated in either an exercise training (ET) group or a control group. The ET group performed exercise training for 45 minutes, three times a week for seven weeks. Patients in both groups received a leaflet for daily exercising at home. HRV parameters comprising, the standard deviation of normal R-R intervals (SDNN), the square root of the mean of the squares of successive R-R intervals differences (RMSSD) ,the percentage of successive R-R intervals differing from more than 50 ms (PNN50), using 24-hour Holter electrocardiographic monitoring was measured. RESULTS After the intervention, the SDNN improved in the ET group (P=0.002), while changes in all remaining HRV indices were insignificant (P≥0.05). The control group showed no significant changes in any HRV parameters (P≥0.05). Changes in SDNN in the ET group were significantly different from the control group (P=0.003). At baseline, our results revealed a significant weak correlation between ejection fraction and SDNN (r =0.279, P=0.047). However, ejection fraction did not correlate significantly with RMSSD and PNN50. CONCLUSION Exercise training is safe and feasible in post percutaneous coronary intervention patients, even in those with reduced ejection fraction. In a seven-week period, exercise training was effective in improving HRV in heart failure patients after percutaneous coronary intervention.

Abstract
Objective The purpose of this study was to compare the effects of scapulothoracic (ST) mobilization plus physical therapy (PT) with PT alone in patients with mechanical neck pain. Methods This double-blinded randomized clinical trial was conducted at Shiraz School of Rehabilitation Sciences and involved 46 patients with mechanical neck pain and scapular dyskinesia. The patients were randomly assigned to the ST mobilization + PT group (scapulothoracic mobilization and physical therapy) or the PT group (physical therapy treatment) by a computer-generated randomized table of numbers. Both groups received 5 sessions of treatment during 1 week. Pain intensity and grip strength were evaluated 3 times: baseline, after the first session, and after the fifth session. Furthermore, functional disability of the upper limbs and the neck were evaluated before and at the fifth session. Results The results showed that the pain intensity was reduced and grip strength increased significantly after the first session (P = .01) and at the end of the treatment (P = .01) in the ST mobilization + PT group in comparison with the PT group. Also, the mean difference of upper limb (P = .01) and neck disability (P = .02) decreased significantly in the ST mobilization + PT group in comparison with the PT group. Conclusion Scapulothoracic mobilization in combination with physical therapy may be superior to physical therapy alone in reducing pain intensity, maximizing grip strength, and reducing upper limb and neck disability in mechanical neck pain.

BACKGROUND In patients with chronic low back pain (CLBP), postural control is a demanding task in terms of attention. Although the attentional demands of postural control have been investigated in these patients, the attentional demands of postural recovery during dual task performance have not been evaluated in patients with nonspecific CLBP. OBJECTIVE To investigate the effect of dual tasking on anticipatory and compensatory postural adjustments in response to an external perturbation in patients with nonspecific CLBP. METHODS Twenty-five patients with nonspecific CLBP of at least 3 months' duration and 25 healthy persons were exposed to predictable and unpredictable external perturbations. The attentional demands of postural adjustments were evaluated while participants simultaneously performed a cognitive task. Onset latency and integrated electromyographic activity of the trunk and leg muscles were compared between dual task (postural recovery and backward digit span memory) and single task conditions (postural recovery only). RESULTS The results showed delayed activation of the tibialis anterior (agonist) and early activation of the gastrocnemius (antagonist) muscles during the dual task in patients with nonspecific CLBP compared to healthy participants. Integrated electromyographic activity was significantly greater in the dual task than the single task condition in the gastrocnemius (antagonist) muscle in patients with nonspecific CLBP compared to healthy persons during unpredictable perturbations. CONCLUSION The impaired ankle muscle activities during a cognitive task suggest that postural control recovery following external perturbation requires attentional resources in patients with nonspecific CLBP. This may increase the risk of re-injury in people with nonspecific CLBP while they perform an attentionally demanding task in more difficult circumstances.

Trunk Kinematic Analysis during Gait in Cerebral Palsy Children with Crouch Gait Pattern. J Biomed Phys Eng 2018; 8:281-288. [PMID: 30320032 PMCID: PMC6169120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2016] [Accepted: 12/08/2016] [Indexed: 11/13/2022]
Abstract
BACKGROUND Deficits in upper body movement have received little attention during gait in cerebral palsy (CP) children with crouch gait pattern (CGP). OBJECTIVE Purpose of this research is to describe the correlation of trunk movement with the excessive knee flexion and ankle kinematic in CP children with CGP. MATERIAL AND METHODS Gait analysis data from 57 limbs of diplegic CP children with CGP and 26 limbs of normal children was gathered. Kinematic parameters of trunk in relation to the pelvis were extracted in the sagittal, transverse and coronal planes. CP limbs were clustered using K-means cluster analysis according to the knee flexion angle at initial contact and the mean position of ankle joint during the stance phase of gait cycle, to three clusters. Pearson correlation coefficient between knee, ankle and trunk kinematic variables was assessed. Differences between clusters were analyzed with Kruskal-Wallis and post hoc tests. RESULTS The results revealed: 1) crouch clusters had more trunk obliquity and rotation mean position than normal; 2) the range of motions of the trunk obliquity and rotation exhibited significant differences between crouch and normal clusters; 3) the level of excessive knee flexion had positive correlation with the trunk mean position in all planes; 4) the ankle kinematic at stance phase was associated with the trunk mean position in all planes. CONCLUSION The results revealed the trunk mean position is correlated with the excessive knee flexion severity and ankle joint kinematic in CP children with CGP.

Abstract
BACKGROUND Typing is a common activity involving repetitive motion that can increase the risk of work-related injuries. To the best of our knowledge, the effect of typing on the pinch strength has not been investigated so far. OBJECTIVE To investigate the pinch strength amongst female typists and non-typists. METHOD Thirty female typists and 30 female non-typists, aged 20-30 years old, participated in this prospective study. The pinch strength of the second, third, fourth and fifth fingers of the dominant hand was measured in a sitting position, using a pinch gauge. The data were analyzed using independent sample t-test. RESULTS The results showed that there were significant differences in the pinch strength of the second, third and fourth fingers between the two groups. The strength of these fingers was reduced more than that in female non-typists. CONCLUSION Our results suggest that pinch strength might have decreased in female typists due to sharing common attentional resources, muscle fiber composition, and muscle fiber fatigue.

Abstract
Background: This study aimed to compare the effects of combined endurance-resistance training (CT) versus endurance training (ET) on some cardiovascular markers in patients with heart failure after percutaneous coronary intervention (PCI). Materials and Methods: The study applied a randomized, controlled design in which 75 patients with heart failure who had undergone PCI were randomly assigned to one of three groups: ET, CT, and control. The ET group performed ET for 45 min, three times a week for 7 weeks. The CT group performed the same ET for 30 min followed by a resistance exercise protocol. The control group received usual care. Functional capacity, N-terminal pro-brain natriuretic peptide (NT-pro BNP), and high sensitivity C-reactive protein (hs-CRP) levels were measured. Results: After the intervention, functional capacity was improved (P < 0.001) and NT-pro BNP level was significantly reduced (P = 0.004 in the CT group, P = 0.002 in the ET group). Hs-CRP level was significantly reduced only in the ET group (P = 0.030). The control group showed no significant changes in any cardiovascular parameters (P ≥ 0.05). Changes in functional capacity (P < 0.001) in both training groups were significantly different from the control group. No significant differences were found between the ET and CT groups regarding changes in all outcomes after exercise training (P ≥ 0.05). Conclusion: Exercise training is safe and feasible in post-PCI patients, even in those with reduced ejection fraction. CT was as effective as ET in reducing NT-pro BNP level and improving functional capacity in heart failure patients after PCI.

Abstract
BACKGROUND peripheral neuropathy is the most common problem of diabetes. Neuropathy leads to lower extremity somatosensory deficits and postural instability in these patients. However, there are not sufficient evidences for improving postural control in these patients. AIM To investigate the effects of transcutaneous electrical nerve stimulation (TENS) on postural control in patients with diabetic neuropathy. METHODS Twenty eighth patients with diabetic neuropathy (40-55 Y/O) participated in this RCT study. Fourteen patients in case group received TENS and sham TENS was used for control group. Force plate platform was used to extract sway velocity and COP displacement parameters for postural control evaluation. RESULTS The mean sway velocity and center of pressure displacement along the mediolateral and anteroposterior axes were not significantly different between two groups after TENS application (p>0.05). CONCLUSION Application of 5min high frequency TENS on the knee joint could not improve postural control in patients with diabetic neuropathy.

Abstract
BACKGROUND The number of diabetic patients is increasing in the world. Peripheral neuropathy is the most important problem of diabetes. Neuropathy eventually leads to balance impairment which is the main cause of falling down in these patients However, not sufficient evidences available to compare different protocols for improving balance in diabetic patients. OBJECTIVE This study aimed to compare the effects of two therapeutic exercises on clinical balance measures in patients with type II diabetic peripheral neuropathy. METHODS The study was performed on 60 patients with diabetes categorized randomly into three groups: an intervention group (N=20) that received ball training exercise, another intervention group (N=20) that received Frenkel exercise and a control group (N=20) that received no interventions. Exercise training session was performed for 3 weeks. Then, clinical balance measures were computed in the three groups. Paired t-test and one-way ANOVA were used to analyze the collected data. RESULTS Both types of therapeutic exercise programs significantly improved balance in single leg stance, star excursion test, and Berg balance scale test (P˂0.05) compared to the control group. Besides, this was more significant in the ball training group (P˂0.05). CONCLUSIONS To improve balance in diabetic neuropathy, Swiss ball exercise is preferred compared to Frenkel training.

Abstract
OBJECTIVE To evaluate and compare the effects of stretching and combined therapy (stretching and massage) on postural balance in people aged 50 to 65 years. METHODS Twenty-three subjects participated in this nonrandomized clinical trial study. Each participant randomly received plantar flexor muscle stretching (3 cycles of 45 seconds with a 30-second recovery period between cycles) alone and in combination with deep stroking massage (an interval of at least 30 minutes separated the two interventions). The data were recorded with a force platform immediately after each condition with eyes open and closed. The center of pressure displacement and velocity along the mediolateral and anteroposterior axes were calculated under each condition. The data were analyzed with multiple-pair t-tests. RESULTS The center of pressure displacement and velocity along the mediolateral axis increased after both stretching and the combined intervention. There were significant differences in both values between participants in the stretching and combined interventions (p<0.05). CONCLUSION Plantar flexor muscle stretching (for 45 seconds) combined with deep stroking massage may have more detrimental effects on postural balance than stretching alone because each intervention can intensify the effects of the other.

Abstract
BACKGROUND To investigate the effects of kinesio taping on postural control in stroke patients. MATERIALS AND METHODS Forty stroke patients aged 30 to 60 years were randomly divided into an experimental and a control group. In the experimental group, kinesio tape (KT) was applied directly on the skin over the affected ankle in the direction of dorsiflexion and eversion to correct the equinovarus deformity. The tape was kept on the ankle for 1 day. The results were measured with the forward reach test, lateral reach test, Berg Balance Scale (BBS), and timed up and go test. Center of pressure (COP) displacement and velocity were also measured while the patients stood on a force plate. All variables were measured on the first day immediately after taping and 24 hours later in the KT group, and on the first day and also 24 hours later in the control group. RESULTS There was a statistically significant difference in BBS between the first day and 24 hours later in the KT group (P = .01). The forward reach test and mediolateral displacement of the COP differed significantly after taping in the experimental group compared to the control group (P = .04). Immediately after taping, BBS improved significantly in the KT group (P = .02). CONCLUSIONS The application of KT improved forward reach test results and displacement of the COP in stroke patients.

Abstract
Objective: The effects of transcutaneous electrical nerve stimulation (TENS) on postural control in patients with low back pain which is not well known. This study aimed to evaluate the effects of TENS on postural control in chronic low back pain. Methods: This study was an experimental research design. Twenty-eight patients with chronic LBP (25-45 Y/ O) participated and by using a random allocation, were divided to samples who participated in this study. The mean center of pressure (COP) velocity and displacement were measured before, immediately and 30 min after the intervention. The tests were done with eyes open and closed on a force platform. Sensory electrical stimulation was applied through the TENS device. The descriptive statistics, independent sample T-test and ANOVA with repeated measurement on time were used for data analysis. Results: The results of the present study demonstrated that the application of the sensory electrical stimulation in chronic LBP patients showed a statistically significant improvement in postural control in Medio-lateral direction with no corresponding effect on the anterior-posterior direction immediately following the TENS application and 30 minutes after it in closed eyes conditions as compared to baseline. The application of TENS decreased the displacement and velocity of COP (p≤0.05), 30 minutes after the application of sensory electrical stimulation. The results showed that the mean displacement and velocity of COP decreased in eyes open position (p≤0.05). Also, immediately and 30 minutes after the application of sensory electrical stimulation, COP displacement and velocity in ML direction with eyes closed significantly decreased in the intervention group in comparison with control group (p≤0.05). Conclusion: The application of TENS in patients with chronic low back pain could improve postural control in these patients.
