The ability to maintain standing balance influences the risk of falling while performing everyday activities. Postural control is the base of balance that is the result of collaboration of visual, vestibular and somatosensory systems. Single leg stance test is a simple clinical method to evaluate static balance. In this test, the center of body mass is on a small support level and need to make corrective movements to create balance by postural control system. Kinesiotaping and stretching of ankle plantar flexor muscles used in physical therapy are effective in improvement of postural balance. Kinesiotaping is effective in maintaining balance by activates cutaneous receptors and promoting alpha motor neuron stimulation. Moreover, stretching is a common treatment used to prevent muscle shortness and increase the range of motion that improves the balance. Aim Therefore the aim of current study was to compare th...

Accordingly, one reason of CGH is myofascial trigger points. The purpose of this study was to investigate the effect of one session dry needling (DN) of myofascial trigger points of the sternocleidomastoid (SCM) muscle in patients with CGH. Materials and Methods: In this before-and-after clinical trial, 16 females aged 18–60 years with a clinical diagnosis of CGH were enrolled. All of the patients received one session DN into the myofascial trigger points of the SCM muscle. Headache index (HI), headache duration, headache frequency, and headache disability index (HDI) were assessed at 2 weeks before and 2 weeks after the intervention. This study was registered in Clinical Trials as IRCT20181109041599N1. Results: One session DN into myofascial trigger points of the SCM muscle showed a significant improvement in HI (P < 0.001). Duration and frequency of headache as well as HDI significantly reduced after intervention (P < 0.001). Conclusion: One session DN into myofascial trigger points of the SCM muscle was effective on improvement of HI, headache duration, headache frequency, and HDI in patients with CGH.

It is characterized by pain, reduced proprioception, and altered pattern of vastus muscle activation, which effectively maintain the balance needed for performing daily living activities such as walking and running. One treatment method that can reduce pain and improve balance in people with PFPS is Kinesiology Taping (KT). Considering the physiological and anatomical differences in the knee structure of men and women and the importance of studying the effect of KT on the dynamic balance of men with PFPS, this study aims to compare the effect of KT on dynamic balance and pain of men and women with unilateral PFPS. Materials & Methods This is a quasi-experimental and non-randomized clinical trial. The participants were 30 males and 31 females aged 18-40 years suffering from unilateral PFPS. They were recruited using a convenience sampling method. First, the subjects performed the Y-balance test three times in each of the anterior, posteromedial, and posterolateral directions. The maximum score obtained from the three repetitions in each direction was divided by the limb length and recorded in percentage as a dynamic balance score. After 5 minutes of rest and performing initial tests, the subjects performed the intervention. In this stage, KT with a tension equal to 50%-75% of its initial length was applied on the patella of the involved limb to cause medial glide. The effectiveness of KT was examined under a single-leg squattest. For this purpose, all subjects performed unilateral squatting on their affected leg for 10 seconds with 45 degrees of knee flexion before and after KT, while their pain level was recorded using the visual analog scale. In case of a 50% reduction in pain, the subjects were allowed to enter the final stage (performing the Y-balance test); otherwise, patellar taping was repeated to obtain the appropriate pain reduction. Results Within-group comparison of balance parameters before and after KT using the paired t-test showed an increase in the reach distance at three directions in the Y-balance test, revealing a significant improvement in the dynamic balance following KT (P<0.05). According to the independent t-test results, there was no significant difference in balance parameters between males and females before and after the intervention (P>0.05). Moreover, the pain was significantly reduced in both genders after KT (P<0.05), but its difference between men and women was not statistically significant (P>0.05). Conclusion KT is an appropriate therapeutic intervention for improving dynamic balance and reducing pain in people with PFPS. It seems that KT has the same effect on dynamic balance and pain of women and men with PFPS.

Kinsiotaping and stretching techniques are effective in balance improvement. To the best of our knowledge, no study have compared the effects of kinesiotaping and stretching of gastrocnemius on balance in elderly. So, we aimed at comparing the effects of these two methods on balance in elderly. Materials and methods: In this randomized clinical trial, 40 elderly women and men were randomly assigned into 2 groups of kinesiotaping and stretching. Inhibitory tape was applied on the gastrocnemius while in stretching group, the muscle was stretched for 60 seconds in 4 times. The static balance was examined before and after the interventions, using single leg stance test and checking the changes of center of pressure by force plate. According to normal distribution of data, Independent t-test was used to compare the means between groups and paired t-test was used for within group analysis. Results: ...

The muscular disorders observed in patients with CGH, relation between head and neck posture and cervical muscles dysfunction, and association between pelvic alignment and spinal curves highlight the importance of postural assessment in these patients. Therefore, the objective of this study was the assessment of spinal and pelvic posture in men with CGH via photogrammetry in static standing position by measuring different angles. Materials and Methods: In this case-control study, 10 men with CGH and 10 healthy men with matched age and body mass index (BMI) were recruited. A digital camera was used to take photographs from anterior, posterior, and lateral views (3 photographs from each viewpoint). The postural angles were measured using the AutoCAD software. Results: Among the measured postural angles, the mean of cervical inclination (C2-T2...

Type 2 diabetes mellitus in long term leads to vascular insufficiency. It seems that contrast bath is useful for patients with diabetes mellitus due to the increase in blood flow and vascular pumping. The purpose of this study is to investigate the effect(s) of contrast bath on circulation of contralateral lower limb in women with type 2diabetes mellitus compared to healthy subjects. Methods: Fifteen diabetic females aged between 30-60 years, who were diagnosed with type 2 diabetes, and 30 matched control females participated in this research. The oral temperature, skin temperature of the first web space of the foot, and the pulse of dorsalis pedis artery were measured and recorded. These results were evaluated prior to, immediately and 10 minutes after the contrast bath. The contrast bath protocol included the immersion of the right foot in the warm bath (38-44 0 C) for fo...

Various grades of KOA lead to change in gait pattern by different compensatory mechanisms. Spatiotemporal parameters of gait can be influenced by KOA maybe as a strategy to reduce pain and functional adaptation. Most researches are agreed on reduction of gait stride length (2-5) and cadence (6, 7) in KOA patients in comparison to control normal groups. But there is controversy about them. The present study will discuss the effect of KOA severity on gait spatiotemporal parameters. Aim: To determine how KOA severity will affect stride length, walking speed and cadence.

The purpose of this study was to investigate the relationship between various severity of KOA and the forces applied to the lower limb during walking. Sixty eight limbs were divided into three groups of mild, moderate and severe KOA and a healthy normal group according to the Kellgren–Lawrence scale. The subjects walked with a self-selected speed to collect five successful trials. The components of ground reaction forces i.e., medio-lateral (ML), first peak of antero-posterior (AP1), second peak of antero-posterior (AP2), first peak of vertical (VP1), second peak of vertical (VP2) and vertical valley (V.V) were collected. AP1 and AP2 had decreasing pattern with increasing disease severity. Although ML Peak and VV have shown rising trend from normal people to severe KOA, ML difference was not significant in various groups ([Formula: see text]). In addition, the VP1 did not differ significantly among the subjects. In contrast, the VP2 decreased significantly in OA subjects ([Formula: see text]). It seems that AP1 and VP2 components are more sensitive to KOA, which may be used to represent severity of knee OA.

The present study aimed to assess the validity, reliability, and cross-cultural adaptation of the Persian version of the KOS-ADL scale. Methods: In this cross-sectional and psychometric study, 130 patients (14 men and 116 women) with different grades of knee osteoarthritis were recruited. The construct validity of the scale was examined through the correlation between the domains of KOS-ADL and the subclasses of the knee injury and osteoarthritis outcome score (KOOS). To assess the test-retest reliability, 40 of the participants were requested to fill in the questionnaire again with an 8-day interval. The internal consistency of the questionnaire and its subclasses was evaluated with Cronbach's alpha coefficient. To evaluate construct validity, concurrent construct validity was examined with a correlation matrix using Pearson's correlation coefficients between the KOS-ADL domains and KOOS total score and subclasses. The test-retest reliability was analyzed using the intra-class correlation coefficient (ICC). The Kappa coefficient was used to determine the intra-rater agreement. Results: The Persian version of the KOS-ADL scale had good reliability (ICC=0.79) and internal consistency (α=0.92). There was a good correlation between the KOS-ADL total score and KOOS subclasses (r≥0.71, P≤0.001). Conclusion: The Persian version of the KOS-ADL scale is a valid and reliable instrument to evaluate the symptoms and functional status of people suffering from knee osteoarthritis.

Gait alterations are of the most common complications of KOA and may lead to functional dependency and work disability (3).
Aim: The purpose of this study is to review the gait differences between osteoarthritic patients and healthy individuals.
Materials and Methods: In this study we have searched from April 2012 in Pub Med data base for relevant studies published in two recent decades from 1990 until now. The key words used in this article include "knee osteoarthritis" AND "gait" in combination with "severity" and "knee adduction moment". Abstracts articles that analyzed Kallgren and Lawrence progression in examination of KOA and evaluated the kinetic and kinematic parameters from 3D gait analysis, were eligible for inclusion.
Results: More than 100 articles are published about KOA severity and changes of knee adduction moment in osteoarthritic patients' gait. The major differences in kinetic and kinematic parameters between osteoarthritis patients and healthy subjects are in coronal plane (4). Most of the researchers believe that External knee adduction moment is a valid index for medial knee osteoarthritis(5) and increasing of this parameter has a correlation to disease progression(6) but some of them have shown that this correlation is only in severe degrees not in low grades. It seems that knee adduction angular impulse is more sensitive in mild osteoarthritis (7, 8).
Conclusion: Gait changes are the most common variation of knee osteoarthritis. The changes that most of the researches agreed with them are increase of KAM. There is no consensus about which factors have the greatest impact on disease progression yet and there is need for further studies.

Various grades of KOA lead to change in gait pattern by different compensatory mechanisms. Spatiotemporal parameters of gait can be influenced by KOA maybe as a strategy to reduce pain and functional adaptation. Most researches are agreed on
reduction of gait stride length (2-5) and cadence (6, 7) in KOA patients in comparison to control normal groups. But there is controversy about them. The present study will discuss the
effect of KOA severity on gait spatiotemporal parameters.
Aim: To determine how KOA severity will affect stride length, walking speed and cadence.
Materials and Methods: Thirty four women aged between 40-70 years diagnosed with medial KOA were systematically divided in to three groups of mild, moderate and severe OA and a group of normal subjects. KOA severity was classified according to the (K–L scale) using atlas of the Osteoarthritis Research Society International (OARSI). Data collected using the motion analysis system in the Musculoskeletal Research Center of Faculty of
Rehabilitation Sciences, Isfahan University of Medical Sciences. The subjects were asked to walk with a comfortable self-selected speed along the 10-meter walking path to collect five successful trials and sampled at frequency of 120 Hz. The normality of all parameters was evaluated by Shapiro Wilk test and parametric test used for statistical evaluation to determined difference between the mean values of the parameters between groups by SPSS software (SPSS, version 16, SPSS Inc. Chicago, IL, USA)
Results: The ANOVA results of spatiotemporal parameters and post hoc analysis shown "stride length" is the only parameter that is significantly different in normal groups with all of the OA subjects (P<0.05). Walking speed in healthy people was significantly more than moderate and severe KOA groups (P=0.003, P= 0.00 respectively) however, difference to
mild KOA was not significant (P=0.81). Speed was not different between mild and moderate KOA groups (P=.41), but there was a significant difference in mild and severe OA subjects (P=0.007). The cadence was significantly different only between healthy persons and severe osteoarthritis subjects (P=.005).
Conclusions and clinical implication: It seems that "stride-length" is the key parameter to distinguish normal subjects from KOA client even in early stages. We recommend practitioners to observe patient’s apparent gait pattern with more focus on their stride length in clinics
