The aim of the study was to explore whether passive stiffness of the hamstrings influences the strategy of maintaining postural stability. A sample of 50 subjects was selected; the final analyses were based on data of 41 individuals (33 men, 8 women) aged 21 to 29 (mean = 23.3, SD = 1.1) years. A quasi- experimental ex post facto design with repeated measures was used. Categories of independent variables were obtained directly prior to the measurement of the dependent variables. In stage one of the study, passive knee extension was measured in the supine position to assess hamstring stiffness. In stage two, the magnitude of postural sway in antero-posterior direction was measured, while varying the body position on a stabilometric platform, both with and without visual control. The margin of safety was used as a measure of postural control. The magnitude of the margin of safety increased significantly between the open-eye and closed-eye trials. However, although we registered a visible tendency for a larger increase of the margin of safety associated with lower levels of passive hamstrings stiffness, no significant differences were found. Therefore, this study demonstrated that hamstring stiffness did not influence the strategy used to maintain postural stability.

Hereditary motor and sensory neuropathy, also known as Charcot-Mari-Tooth disease (CMT), belongs to a complex and heterogeneous group of hereditary peripheral nerve diseases. The most common form of this disease is the motor and sensory neuropathy type 1A (CMT1A). The main symptoms of the disease are symmetric paresis, located initially in the distal segments of the limbs, gait and balance problems, bone deformities and altered sensation. The aim of the study is to identify and review literature on maintaining postural control in patients with hereditary motor and sensory neuropathy and to provide information on what causes balance impairment. The literature review was conducted by searching Medline, Embase and Scopus databases. The following keywords were used in the search: ‘hereditary motor sensory neuropathy’, ‘charcot marie tooth’, ‘hereditary neuropathy’, ‘balance’, ‘posture’, ‘balance control’, ‘postural control’, ‘postural organization’, ‘somatosen*’. The authors took into consideration all articles that appeared in the search up to September 2020. Additionally, the bibliography of selected articles was searched. The search identified 310 articles. After the final selection 7 articles were included in the review. The conclusions are: 1. There are very few studies on postural control in patients with hereditary motor and sensory neuropathy. 2. Investigators use different methodology to assess postural control, which makes it difficult to draw clear conclusions about the cause of balance impairment. 3. There is a need for a welldesigned study on a larger number of patients divided into groups according to the type of hereditary neuropathy.

The aim of the present study was to examine the relationships between balance performance as measured by the Balance Error Scoring System and functional performance in football players. Twenty-two football players from University League Final Group in Turkey (age 23.05 ± 1.65 years, height 176.58 ± 6.99 cm, weight 68.80 ± 7.00 kg) volunteered to participate in the study. Postural performance was measured by the Balance Error Scoring System (BESS). For functional performance, standing broad jump, triple-hop, vertical jump, four-line sprint and three-corner run test were used. There was not a statistically significant relationship among the all BESS scores and triplehop in non-dominant leg, power, four-line sprint, and three-corner run performances (p<0.05). Triple-hop in dominant leg performance correlated with foam surface, tandem leg and total BESS score (r = 0.755, p < 0.01; r = 0.664, p < 0.05; r = 0.713, p< 0.01, respectively). Standing broad jump performance correlated with foam surface, tandem leg and total BESS score (r = 0.737, p < 0.01; r = 0.692, p < 0.05; r = 0.617, p< 0.05, respectively). There was a statistically significant relationship among the single leg BESS score and vertical jumping performance (r = -0.596, p<0.05). In conclusion, the activities requiring explosive power may reflect the ability of managing a balanced posture but the activities in which time period is longer may not.

Background: Obstacles are a common cause of falls. Mobility tests for healthy elderly that involve maneuvering over an obstacle have not been fully developed. We have shown that a small box placed on the walkway of a representative mobility test, the Timed Up & Go (TUG) for the frail elderly, influences the test performances of the healthy female elderly. However, the validity of this obstructed TUG (OTUG) as a fall risk assessment tool has not yet been clarified. This study examined the relationship between the OTUG and the fall risk for the healthy elderly. Material/Methods: 66 healthy community-dwelling elderly and 19 healthy elderly persons living in a nursing home participated in the study. In the TUG, participants stood up from a chair, walked 3 m, turned around, walked back to the chair and sat down. In the OTUG, a box (height 5 cm, depth 10 cm) was placed at the midpoint of the walkway. Participants were instructed to step over it safely. Times required to perform the respective test were recorded. Fall risk scores, the required times (s) for the TUG and OTUG and difference ratios (OTUG/TUG x 100) (%) were analyzed. Results: Correlations between fall risk and other mobility performances were all significant. However, the correlation between fall risk and the OTUG (r = 0.60) was significantly higher than that between fall risk and the TUG (r=0.49) (t=3.733, p<0.001). Conclusions: Compared to the TUG, the OTUG is more valid for assessing the fall risk of community- dwelling healthy elderly

Soccer kicking kinematics has received wide interest in literature. However, while the instep-kick has been broadly studied, only few researchers investigated the inside-of-the-foot kick, which is one of the most frequently performed techniques during games. In particular, little knowledge is available about differences in kinematics when kicking with the preferred and non-preferred leg. A motion analysis system recorded the three-dimensional coordinates of reflective markers placed upon the body of nine amateur soccer players (23.0 ± 2.1 years, BMI 22.2 ± 2.6 kg/m2), who performed 30 pass-kicks each, 15 with the preferred and 15 with the non-preferred leg. We investigated skill kinematics while maintaining a perspective on the complete picture of movement, looking for laterality related differences. The main focus was laid on: anatomical angles, contribution of upper limbs in kick biomechanics, kinematics of the body Center of Mass (CoM), which describes the whole body movement and is related to balance and stability. When kicking with the preferred leg, CoM displacement during the ground-support phase was 13% higher (p<0.001), normalized CoM height was 1.3% lower (p<0.001) and CoM velocity 10% higher (p<0.01); foot and shank velocities were about 5% higher (p<0.01); arms were more abducted (p<0.01); shoulders were rotated more towards the target (p<0.01, 6° mean orientation difference). We concluded that differences in motor control between preferred and non-preferred leg kicks exist, particularly in the movement velocity and upper body kinematics. Coaches can use these results to provide effective instructions to players in the learning process, moving their focus on kicking speed and upper body behavior

Introduction: The authors present the influence of two physiotherapy programmes on the re-education of motor behaviour in patients after ischemic stroke. One of them is a programme based on exercises combining PNF and NTD Bobath elements, while the other is a deep trunk muscle exercises with the use of the PUM armchair. Material and methods: The study material was a group of 60 patients of both sexes who suffered ischemic stroke resulting in hemiparesis. They were divided into two groups. Group I consisted of 18 women (60%) and 12 men (40%) who followed the author’s programme of deep muscle activation exercises using the PUM armchair. Group II consisting of 15 women (50%) and 15 men (50%) followed the exercise programme using standard methods, i.e. based on PNF and Bobath methods. Results: They indicate the effectiveness of both methods, with the predominance of the author’s programme. Conclusion: The improvement of deep muscle activity in the examined group of patients has positive influence on their muscle tone, balance and postural control, which in turn, reduces muscle tension, improves gait stereotype and load characteristics of lower limbs. ischemic stroke, postural control, deep muscles Article received: 30.01.2018; Accepted: 30.03.2018

Background. Football players are exposed to frequent supination injuries of the talocrural joint and repeated injuries lead to chronic ankle instability (CAI). Previous study results indicate that CAI do not significantly affect postural stability under static conditions, however, it is suspected that it may aggravate under dynamic conditions. Therefore, the goal of this study was analysis of postural stability under dynamic conditions with regard to dominance of the lower limb. Material and methods. The sample comprised 28 football players (age = 26.1±5.4), included in CAI group according to the Ankle Consortium inclusion criteria and 37 football players (age = 27.3±5.2) with no history of supination injuries, included in the control group (CTRL). Biodex Balance System platform was used for postural stability assessment during single leg standing under dynamic conditions. Results. During single leg standing statistically significant between-group differences were noted (p<0.05). The following values were obtained in CAI and CTRL groups respectively: CAI: (OSI 7.01±2.43; APSI 5.18±1.85), CTRL: (OSI 5.27±1.42; APSI 3.98±1.42). During single leg standing similar trends were observed. CAI group obtained statistically significant (p<0.05), higher values of the studied parameters. Lower limb function played an important role in CTRL group as for OSI (dom. 7.23±1.48; n-dom. 5.64±1.51) and MLSI (dom. 3.8±0.64; n-dom. 3.07±0.97) parameters. Conclusions. CAI impairs postural stability in footballers under dynamic conditions, both during single and double leg standing, however, the lower limb function significantly affects postural control only in CTRL group.

Wstęp. Piłkarze nożni narażeni są na częste urazy supinacyjne stawu skokowo-goleniowego, który, wielokrotnie powtarzany, sprzyja powstaniu przewlekłej niestabilności (CAI). Dotychczasowe badania wskazują, iż CAI nie wpływa istotnie na stabilność posturalną w warunkach statycznych, jednakże istnieją przypuszczenia, że w warunkach dynamicznych może mieć istotne znaczenie. Z tego powodu celem naszych badań była analiza stabilności posturalnej w warunkach dynamicznych, z uwzględnieniem dominacji kończyny dolnej. Materiał i metody. W badaniu wzięło udział 28 piłkarzy nożnych (w wieku 26,1±5,4) zakwalifikowanych do grupy CAI zgodnie z kryteriami kwalifikacji International Ankle Consortium oraz 37 piłkarzy (w wieku 27,3±5,2), bez wcześniejszej historii urazu supinacyjnego, tworzących grupę kontrolną (CTRL). Do oceny stabilności posturalnej w pozycji stania obunóż oraz jednonóż w warunkach dynamicznych wykorzystano platformę Biodex Balance System. Wyniki. W postawie obunóż zaobserwowano różnice istotne statystycznie (p<0,05) między grupami CAI (OSI 7,01±2,43; APSI 5,18±1,85) i CTRL (OSI 5,27±1,42; APSI 3,98± 1,42). W postawie jednonóż zauważono podobne trendy, gdzie CAI uzyskała istotnie statystycznie (p<0,05) wyższe wyniki w analizowanych parametrach. Funkcja kończyny dolnej odgrywała istotną rolę w grupie CTRL w parametrach OSI (dom. 7,23±1,48; n-dom. 5,64±1,51) oraz MLSI (dom. 3,8±0,64; n-dom. 3.07±0,97). Wnioski. CAI upośledza stabilność posturalną u piłkarzy nożnych w warunkach dynamicznych zarówno w postawie obunóż, jak i jednonóż, jednakże funkcja kończyny dolnej istotnie wpływa na kontrolę posturalną jedynie w grupie CTRL.

The purpose of this study was to examine the differences in the ground reaction force (GRF) patterns between elite and novice players during two types of handball shots, as well as the relationships between throwing performance and the GRF variables. Ball velocity and throwing accuracy were measured during jump shots and 3-step shots performed by 15 elite and 15 novice players. The GRF pattern was recorded for the vertical and the anterior-posterior GRF components (Kistler forceplate type-9281, 750Hz). One-way ANOVA was used for the group differences and the Pearson coefficient for the correlation between throwing performance and GRF variables (SPSS 21.0, p ≤ 0.05). The elite players performed better in both types of shot. Both groups developed consistent and similar GRF patterns, except for the novices’ inconsistent Fz pattern in the 3-step shot. The GRF variables differed significantly between groups in the 3-step shot (p ≤ 0.05). Significant correlations were found only for ball velocity and predominantly for the novice players during the 3-step shot (p ≤ 0.05). The results possibly highlight a shortage in the novice ability to effectively reduce their forward momentum so as to provide a stable base of support for the momentum transfer up the kinetic chain, a situation that may predispose athletes to injury.

Wstęp: Niestabilność posturalna u osób z chorobą Parkinsona (PD) jest jednym z głównych czynników przyczyniających się do zwiększenia upadków i związanych z nimi powikłań. Diagnostyka zaburzeń równowagi opiera się na ocenie kontroli postawy przez ocenę biomechaniczną narządu ruchu, koordynującą szybkość i precyzję wykonywanych ruchów. Warunkiem wykonania precyzyjnego i płynnego ruchu jest skoordynowanie czynności ruchowych oraz bodźców czuciowych z sygnałami płynącymi do układu ruchowego. Cel pracy: Ocena wpływu zaburzeń pozaruchowych (depresji i zaburzeń poznawczych) oraz nasilenia objawów ruchowych na proces planowania i kontroli przebiegu ruchu w chorobie Parkinsona. Materiał i metody: Do badania zakwalifikowano 40 chorych z idiopatyczną chorobą Parkinsona, rozpoznaną zgodnie z kryteriami United Kingdom Parkinson’s Disease Society Brain Bank (UKPDSBB), w stadium II lub III zaawansowania objawów choroby wg Hoehn-Yahra. U wszystkich chorych przeprowadzono badanie fizykalne wraz z oceną w skali UPDRS (Unified Parkinson’s Disease Rating Scale) oraz wykonano przesiewowe testy kliniczne, oceniające funkcje poznawcze (Montreal Cognitive Assessment, MoCA) i zaburzenia depresyjne (Beck Depression Inventory, BDI). Oceny mobilności, stabilności i kontroli ruchu dokonano za pomocą testów: Berg Balance Scale (BBS), testu Tinetti, testu Up and Go (TUG), Dynamic Gait Index (DGI). Wyniki: Wykazano istotną zależność pomiędzy poziomem nasilenia zaburzeń ruchowych (wg UPRDS ON cz. III) a parametrami definiującymi zdolności motoryczne w DGI (R= -0,49, p<0,001), testem oceny mobilności TUG (R=0,4, p<0,01) oraz zaburzeniami równowagi statycznej i dynamicznej w BBS (R=-0, 44, p<0,004). Poziom funkcjonowania poznawczego miał istotny wpływ na mobilność i stabilność chorych, a występowanie zaburzeń depresyjnych nie wpływało na pogorszenie podstawowych reakcji posturalnych w badanej grupie chorych z PD.

Introduction: Postural instability in patients with Parkinson’s disease (PD) is one of the major factors contributing to an increasing number of falls and fall related complications. Diagnosis of balance disorder is based on assessment of postural control by the biomechanical assessment of the musculoskeletal system, coordinating speed and precision of movements. The condition for the performance of precise and smooth movement is coordination of motor activity and sensory signals fl owing to the motor system. Study aim: The aim of the study is to assess the impact of non-motor symptoms (depression and cognitive impairment) and the impact of the severity of motor symptoms on the process of course of movement planning and control in Parkinson’s disease. Material and methods: The study involved 40 patients with idiopathic Parkinson’s disease, diagnosed according to the criteria adopted by the United Kingdom Parkinson’s Disease Society Brain Bank (UKPDSBB), with stage II or III severity of symptoms of the disease according to the Hoehn-Yahr sclae. All the patients underwent physical examination with an evaluation using the UPDRS (Unifi ed Parkinson’s Disease Rating Scale) and screening clinical trials were performed, evaluating cognitive functions (Montreal Cognitive Assessment, MoCA) and depressive disorders (Beck Depression Inventory, BDI). Evaluation of mobility, stability and motor control was done using the Berg Balance Scale (BBS), the Tinetti test, the Up and Go test (TUG) and the Dynamic Gait Index (DGI). Results: There was a signifi cant correlation between the level of severity of movement disorders (according to UPRDS ON part III) and the parameters defi ning motor skills in the DGI (R= -0.49, p<0.001), the TUG test evaluating mobility (R=0.4, p<0.01), and static and dynamic balance disorder using BBS (R=-0.44, p<0.004). The level of cognitive functioning had signifi cant impact on the mobility and stability of patients, and the occurrence of depressive disorder did not affect the deterioration of basic postural reactions in the group of patients with PD.
