Abstract: BACKGROUND AND OBJECTIVES: Low back pain (LBP) is one of the leading forms of chronic pain and is among the leading causes of pain and disability. In this study, we investigated the associations between the severity of disability and fear of movement and pain beliefs as well as the impact of the fear of movement and pain beliefs on the quality of life in patients with chronic LBP. METHODS: A total of 89 patients (42.29 ± 16.05 years) with chronic low back pain were included in the study. The instruments used in the assessments include…the Visual Analogue Scale (VAS), the Oswestry Disability Index (ODI), the Tampa Kinesiophobia Scale (TKS), the Pain Belief Questionnaire (PBQ), and the SF 36-Short Form. Patients were assigned into three groups by disability severity based on ODI scores. Statistical analysis was performed using SPSS 15. RESULTS: No statistically significant intergroup differences were found in TKS and PBQ scores (p > 0.05). A positive correlation was found between TKS scores, age (r : 0.227/p < 0.05), PBQ organic (r : - 0.250/p < 0.05) scores. CONCLUSIONS: Our study revealed high levels of kinesiophobia and similar pain beliefs, independent of the severity level of disability. We believe that cognitive-behavioral therapy that may reduce fear-avoidance behaviors and convert negative pain beliefs into positive ones should be added to rehabilitation procedures for LBP.

Abstract: BACKGROUND: Restoration of functionality in patients with low back pain is one of the most important rehabilitation and societal problems. The aim of this study was to verify the results of the DBC (Documentation Based Care) method used in elderly men. METHOD: This study evaluated the efficiency of DBC treatment on the basis of spinal mobility in sagittal, frontal and transverse planes and a subjective assessment of pain. There were two research groups: one with 187 men over the age of 65, and the other with 187 men under the age of 65. The patients in…the study were carefully selected. All subjects suffered from chronic, non-specific low back pain lasting for a period of at least three months. CONCLUSION: The conducted analyses confirmed that a functional restoration process improved spinal mobility in all planes of movement, decreased pain and functional limitations, and reduced the level of depression.

Abstract: BACKGROUND: There is a wide range of rehabilitation protocols after knee arthroscopic procedures, mainly based on specialist exercises. They comprise of specific stages and key moments but should also be individualized and adjusted to the patient’s needs. OBJECTIVE: The aim of the study was to evaluate the BodyFlow device impact on physical and psychological functioning of the subjects after knee arthroscopy. METHODS: Ninety three patients were randomly divided into the study and control group. Each study group subject performed mild electrostimulation using the BodyFlow device for three weeks, five times a day for…20 minutes along with the standard rehabilitation protocol. Control group subjects were treated according to the standard rehabilitation protocol after knee arthroscopy. Healthy and operated lower limb size, a range of the knee joint motion, and the flexor and extensor strength were measured 3, 6, and 9 weeks after arthroscopy. At each measurement, the SF-36 and KOOS surveys were collected. RESULTS: On study day 21, a positive, statistically significant, difference in the knee joint size, range of flection and extension, flexor and extensor strength as well as all KOOS survey subscales and physical functioning categories included in the SF-36 survey was observed. On study day 63, positive effects persisted and significant differences in other categories included in the SF-36 survey were observed. CONCLUSION: Application of mild electrostimulation using the BodyFlow device has a positive impact on the swelling in the knee joint region, range of motion, extensor and flexor strength as well as physical, psychological, and social functioning.
Abstract: BACKGROUND: Few studies have explored the relationship between muscle strength, range of motion (ROM), and balance in the horizontal plane of the hip joint using three-dimensional (3D) motion analysis. OBJECTIVE: We investigate the relationships of hip internal rotation (IR) and external rotation (ER) ROM, measured using a 3D motion capture system, with hip internal and external rotator strength and single-leg standing balance. METHODS: The participants were 40 healthy adults. Kinematic data on hip ROM were collected using an eight-camera motion analysis system. Hip rotational strength measurements were obtained using hand-held isometric dynamometry. A…Single-leg standing test and a pendular test were conducted to evaluate static and dynamic balance ability using BioRescue. RESULTS: Significant correlations were found between hip strength and each variable measured during hip ROM assessments (p < 0.05). Significant positive correlations were found between the hip IR/ER strength ratio and the IR/ER ROM ratio (r = 0.72, p < 0.01). The subgroup with a normal IR/ER ratio of hip rotator strength and ROM showed significantly better dynamic balance ability than the subgroup with a hip rotator muscle imbalance (p < 0.05). CONCLUSIONS: There is a significant relationship between hip IR/ER strength and IR/ER ROM with a normal hip IR/ER strength and ROM ratio positively affecting dynamic balance ability.

Abstract: BACKGROUND: The main responsibility of the anterior cruciate ligament (ACL) is to restore normal knee kinematics and kinetics. Although so far different research has been carried out to measure or quantify the stresses and strains in the ACL experimentally or numerically, there is still a paucity of knowledge in this regard under different flexion angles of the tibiofemoral knee joint. OBJECTIVE: Understanding the stresses and strains within the ACL under various loading and boundary conditions may have a key asset for the development of an optimal surgical treatment of ACL injury that can better restore normal…knee function. This study aimed to calculate the stresses and strains within the ACL under different flexion angles using a patient-specific finite element (FE) model of the human tibiofemoral knee joint. METHODS: A patient-specific FE model of the human tibiofemoral knee joint was established using computed tomography/magnetic resonance imaging data to calculate the stresses and strains in the ACL under different flexion angles of 0, 10, 20, 30, and 45 ∘ . RESULTS: Although the role of the flexion angle in the induced stresses and strains of the ACL was insignificant, the highest stress and strain were observed at the flexion angle of 0 ∘ . The concentration of the stresses and strains regardless of the flexion angles were also located at the proximal end of the ACL, where the clinical reports indicated that most ACL tearing occurs there at the femoral insertion site. CONCLUSIONS: The results have implications not only for understanding the stresses and strains within the ACL under different flexion angles, but also for providing preliminary data for the biomechanical and medical experts in regard of the injuries which may occur to the ACL at relatively higher flexion angles.

Abstract: BACKGROUND: Previous studies have indicated that the kinematics of the knee joint affect the trunk and pelvis during gait. However, the factors that influence trunk movement in knee osteoarthritis patients during gait after surgery remain unclear. OBJECTIVE: To examine the effect of total knee arthroplasty (TKA) on trunk movement during gait by comparing knee osteoarthritis patients with healthy controls. METHODS: Fourteen medial knee osteoarthritis patients who underwent initial unilateral TKA and 11 controls participated in this study. Knee and hip joint flexion and trunk and pelvic tilts during gait were acquired using a…three-dimensional motion analysis system. Knee joint range of motion, pain, and kinematic data were collected preoperatively and 1 year postoperatively for knee osteoarthritis patients. RESULTS: Knee extension limitation and pain significantly improved postoperatively compared with preoperative stages. Preoperatively, the peak anterior trunk tilt during the stance phase was significantly larger in osteoarthritis patients than in controls. The peak anterior trunk tilt during the stance phase was significantly smaller postoperatively than at preoperative stages. CONCLUSIONS: These results suggest that after TKA, the trunk movements of knee osteoarthritis patients were approximately equal to those of controls, with improvement in clinical outcomes such as knee extension limitation and pain.
Abstract: BACKGROUND: During the rehabilitation phase, physical exercise is a key element that requires an assessment of the best alternatives for application since the pre-prosthetic phase (PPF) for an accurate prescription. Therefore, the assessment of fitness for health (FFH) shall be included in the initial rehabilitation process. OBJECTIVE: To develop a FFH evaluation battery (Evam1) for pre-prosthetic unilateral lower-limb amputees (PPULLA). METHOD: A descriptive study of the theoretical construction and validation of a FFH evaluation battery based on a review of international literature for tests that measure amputee physical capability. RESULTS:…During the scientific literature review, no batteries designed with this goal were found. We therefore designed a battery that was assembled of five tests for anthropometry, aerobic capacity, strength and flexibility. Combined leg and arm cycloergometrics, isokinetic dynamometry, and flexi test are the most reliable tests for the corresponding assessment of each component. CONCLUSIONS: PPF is of great importance, since the basic physical capabilities are altered due to long immobilization and hospitalization periods, inadequate postures, alteration of basic daily activities, and decrease in participation in sports, recreational, and work activities. This is a fundamental proposal, given that the procedures for FFH assessment of PPULLA have been rarely addressed, thus limiting the information on assessment methods, processes and/or tests established for these procedures.
Abstract: BACKGROUND: Balance and mobility impairments, declined musculoskeletal strength and performance, limited range of motion, and poor flexibility are fairly common among older adults. OBJECTIVES: To determine the lower extremity muscle force and to verify the correlation with the gait characteristics and balance in community dwelling older adults. METHODS: Seventy-five adults with a mean age of 75.07 ± 6.28 years were included in the study. All participants were evaluated with the following tests: half squat (HS), decline squat (DS), foot print analysis (step length, step wide, stride length, walking velocity and…cadence) and Tinetti Performance Oriented Mobility Assessment (POMA). RESULTS: HS and DS tests scores were significantly correlated with Tinetti balance and gait assessments scores and gait characteristics, except step wide (p < 0.01). The results of this study showed that the participants who have higher scores in the squat tests, showed higher scores in terms of POMA (p < 0.01). CONCLUSION: Appropriate and direct assessment of lower limb power and performance in balance and gait tests should be done to identify functioning of the older adults. Half and eccentric decline squat tests used in this study were useful, cheap and easy. The squat tests can be used to determine the relationship between balance and gait characteristics, in addition to predicting the musculoskeletal performance in older adults.
Abstract: BACKGROUND: Cervicogenic headache (CeH) is among the common types of headache which has an undesirable influence on the quality of life. The myofascial trigger point (MTrP) within the sternocleidomastoid (SCM) muscle is one of the most important causes of CeH. OBJECTIVE: The purpose of this study was to compare the effect of dry needling (DN) and ischemic compression (IC) on the headache symptoms as well as MTrP-related features in subjects with CeH originating from MTrPs of the SCM muscle using a sonographic method. METHODS: A total of 29 female subjects aged 35.34 ±…12.19 on average with a clinical diagnosis of CeH originating from MTrP in the SCM muscle were randomly divided into the DN, IC, and control groups. Both DN and IC groups received 4 treatment sessions. Headache intensity, duration, frequency, MTrP elastic modulus, MTrP area, and pressure pain threshold (PPT) were assessed 2 weeks before and after treatments. RESULTS: In both DN and IC groups, a significant improvement was found in the headache intensity, duration, frequency, PPT, and MTrP area (P < 0.05). No significant differences were observed between DN and IC (P > 0.05). Pearson correlation revealed a significant correlation between headache intensity and the MTrP elastic modulus (P < 0.05). CONCLUSIONS: Both interventions could reduce headache symptoms, PPT, and MTrP area. Neither intervention was found to be superior to the other in short-term follow-up. IC may be preferred since it has fewer unwanted side effects compared to DN. Based on the data, it may be concluded that some MTrP biomechanical features such as stiffness may influence the produced headache symptoms.

Abstract: INTRODUCTION: The effect of the absence or presence of the Palmaris longus tendon on pinch and grip strength was investigated in this study. Similarly, the effect of the presence or absence of the fifth superficial flexor digitorum on grip strength in the hand was studied. The aim of the present study was to assess the combined effect of these anatomical variations on pinch and grip strength. MATERIALS AND METHODS: In this cross-sectional study, 523 volunteers and their 1046 hands were enrolled. Each hand was assessed for the presence or absence of the Palmaris longus tendon and…for variations in the fifth superficial flexor digitorum function. Then the grip and pinch power of the hands were measured with the Jammar Dynamometer. RESULTS: The presence or absence of Palmaris longus had no effect on grip strength in the individuals studied. Likewise, variations in fifth superficial flexor digitorum function had no effect on grip and pinch strengths. But the results of statistical testing showed the effect of the presence of Palmaris longus on pinch strength (25.38 lbs in hands with Palmaris present vs 24.43 lbs in hands without Palmaris). Pinch and grip power was higher in men than in women and in the right hand than in the left. CONCLUSION: Based on the findings of the present study, it seems that absence of the Palmaris longus tendon is associated with a reduction in pinch strength but has no effect on grip strength, and the variations in the fifth superficial flexor digitorum (flexor digitorum superficialis, or FDS) have no effect on pinch and grip strengths.
