    Introduction
    Physical activity causes postural instability in patients with stroke and healthy subjects, but the impact of the type of physical activity and its durability on postural control in patients with stroke is not clear. Therefore, the aim of this study was to compare the effect of two types of speedy and endurance walking on postural control and the time for returning of postural control to baseline after walking in patients with chronic stroke and healthy subjects.
    Material and
    Methods
    In this non-experimental case-control study, 12 chronic stroke patients (4 female, 8 male; 4 with right hemiparesis and 8 with left hemiparesis) by mean age of 54.16 ± 12.18) years and mean passed duration of injury 28.66 ± 25.11) months and 12 height-, weight-, age- and sex-matched healthy subjects by mean age of 54.33 ± 13.04)years were selected by simple non-probability method. Walking for 6 minutes at maximum speed and walking for 18 minutes at normal speed were considered as speedy and endurance walking, respectively. Mean velocity and path length parameters of postural sway were measured by force platform in tandem standing before walking and immediately, 15 and 30 minutes after walking.
    Results
    The results of this study showed that the main effect of group was not significant in mean velocity (P = 0.487, F = 0.499) and path length parameters (P = 0.375, F = 0.818) while the both mean velocity (P = 0.016, F = 6.83) and path length (P = 0.034, F = 5.13) were greater in speedy walking than endurance walking. Furthermore, the main effect of time was significant in mean velocity (P = 0.017, F = 4.26) and path length (P = 0.002, F = 5.31). None of the interaction effects was significant in any of postural sway parameters.
    Conclusion
    The results of this study indicated that speedy walking results in postural instability more than endurance walking in both patients with chronic stroke and healthy subjects. Time for returning of postural stability to the baseline was 30 minutes after both speedy and endurance walking in both patients with chronic stroke and healthy subjects.

    Introduction
    Multiple sclerosis (MS) is one of the most common disabling diseases in young adults. Common manifestations include fatigue, bladder and bowel disorders, pain, mobility problems, and cognitive impairment. These symptoms seriously affect the activity of daily living (ADL) of people with MS. The purpose of this study to investigate relationship between disability severity and ADL in people with MS.
    Material and
    Methods
    A total of 112 people with MS enrolled in this study. These people were evaluated by Barthel index, Mini Mental Status Examination, the Extended Disability Status Scale for ADL, cognitive ability and severity of disability.
    Results
    In linear regression analysis, independence in ADL is the best of predictor (69%) of disability severity in people with MS. The Pearson correlation test between the severity of disability and independence in ADL showed a significant relationship.
    Conclusion
    Independence in performing ADL can predict disability severity in people with MS.

    Introduction
    Transtibial amputation is the most common amputation in lower limbs. Volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. The goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning.
    Material and
    Methods
    Five unilateral transtibial amputees were participated in this study. After designing and fabricating pneumatic suspension system, its effect on residual limb pistoning was evaluated using photographic method in five static stages including full weight bearing, semi weight bearing, non-weight bearing, 30 N and 50 N loads.
    Results
    Residual limb pistoning was reduced using pneumatic suspension system during non- weight bearing, 30 N and 50 N static loading.
    Conclusion
    The use of pneumatic suspension system would reduce pistoning in supracondylar transtibial prostheses.

    Introduction
    Constraint-induced movement therapy (CIMT) forces the use of the affected side by restraining the unaffected side. The purpose of this article is to explore the changes of motor and functional performance after modified CIMT (mCIMT) in comparison with traditional rehabilitation (TR) in chronic post-stroke patients.
    Material and
    Methods
    A total of 12 patients randomly assigned into two treatment groups. Six patients in the mCIMT group received intensive training in a more affected limb for 2 hours daily, 5 days/week using shaping method over a period of 21 days. Participants less affected limb were restrained in arm - hand splint with a target of wearing it for 5 hours daily. The patients in TR group received bimanual and unilateral activities, stretching, strengthening and coordination exercises of the impaired side, tone modification and coordination exercises of the affected side. The focus was to increase independence in activities of daily living activities using affected side. The motor activity log (MAL), wolf motor function test (WMFT), and modified ashworth scale were measured at pre-test (1 day before training), post- test (1 day after training) and follow-up in 3 weeks after training.
    Results
    The Friedman test found significant differences between pre-test, post-test, and follow-up in MAL and WMFT in mCIMT group. Furthermore, mCIMT group showed significant decreased spasticity (P = 0.030) that measured by ash worth scale. The effect sizes between post-test and pre-test in the above-mentioned outcome measures were moderate to large in mCIMT, ranging from 0.3 to 0.76, but in TR group the effect size were small, ranging from 0 to 0.2.
    Conclusion
    Therefore, it seems that the mCIMT treatment was more effective than TR in improving some parameters.

    Introduction
    Myofascial trigger points (MTrPs) are one of the main characteristics of musculoskeletal disorders. The main purpose of this study was to compare the long-term effects of dry needling (DN) and physical therapy modalities (PT) on the MTrPs of upper trapezius muscle.
    Material and
    Methods
    A total of 34 subjects with upper trapezius MTrP participated in this study. Subjects were randomly assigned into two groups of DN (N = 17) and PT (N = 17). DN group was treated two sessions per week, and PT group was treated three sessions per week. Pain intensity, pressure pain threshold (PPT), cervical range of motion (CROM), and function of upper limbs were assessed every session.
    Results
    Significant decrease of pain (P = 0.002), increase of CROM (P = 0.002), PPT (P = 0.003), and functional improvement of upper limbs (P = 0.001) after treatment occurred in both groups. DN group revealed more improvement than the PT group (P = 0.001).
    Conclusion
    Although both of PT and DN are effective treatments for MTrP, the DN seems to be more effective.
