Deficit in neuromotor control of the core may be a remote contributing factor to thedevelopment of PFP. Application of reliable EMG measures would be helpful to handle thistheory. Therefore, the purpose of this study was to determine the test-retest reliability of thecore and vasti EMG onsets, while ascending/descending stairs.: Patellofemoral pain (PFP) is a common affliction and complex clinicalMethodsand Core EMG onsets during stair stepping were assessed two times a day. Intraclass correlationcoefficients (ICCs) and standard errors of measurement (SEMs) were calculated.: Ten males with PFP and ten healthy controls participated in this study. VastiResultsonsets of control cases (ICC 3,1 ≥ 0.70) except Quadratus Lumborum (QL) which showeda moderate reliability (ICC for ascending=0.59 and for descending = 0.61). In controls,Vasti in both tasks showed the highest absolute re...

The aim of this study was to present a reliable and novel method for evaluation of lumbar spine kinematics in sagital plane. Materials & Methods: In this comparative and validity testing study, 15 low back patients suspected to have LSI and 15 matched healthy subjects were recruited. Pulsed digital videofluoroscopy was used to investigate kinematics of lumbar motion segments during flexion and extension movements. Segmental linear transition and angular displacement, and Pathway of Center of Rotation (PICR) were calculated for each lumbar motion segment. Movement pattern of lumbar spine between two groups and during range of motion were compared.Data were analyzed by statistical methods such as:Chi-square,Kolmogroff-Smirnoff, Independent T test avd ANOVA with repeated measurements. Results: Segmental linear transition was different in patients during...

The objective of this study was to compare the general and segmental curvature in the upper and lower cervical spine of women with postural neck pain and Forward Head Posture (FHP), women without neck pain but with FHP and healthy women. Material and Methods: 45 women were divided into three groups: 15 women with postural neck pain and FHP, 15 women without neck pain but with FHP and 15 healthy women. Photography was used to assess neck posture while cervical spine curvature was measured using fluoroscopy imaging and the Harrison Tangent method. Results: There was no significant difference in general and segmental lordosis in the three groups (P greater-than 0.05). Despite the lack of significant difference, the results showed that the segmental lordosis in C5-C6 and C6-C7 segments was decreased in...

Kinesiotape is a new intervention that recently used in rehabilitation. There are no studies have examined the effect of kinesiotape on rounded shoulder posture. Therefore the purpose of this study was to determine the effect of scapular kinesiotaping and pectoralis minor stretching exercise on forward shoulder angle in female subjects with rounded shoulder posture. Methods: Twenty female students aged between 18 to 25 years old with rounded shoulder posture participated in this study. Then, the subjects were randomly and equally assigned to two groups: the stretch group and the stretch plus kinesiotape group. Both groups were trained for doing home exercise to stretch Pectoralis minor bilaterally for two weeks. Kinesiotape group received kinesiotape on scapular area additionally. Forward shoulder angle was measured in four sessions including pre-intervention (first session), immediately after the fi...

Lateral scapular slide test is used to determine scapular position in coronal plane; however, different studies have shown conflicting results for the reliability of the test in position of 90 degrees of abduction. According to the more functionality of scaption compare to the abduction as well as scaption is a familiar task for athletes, in current study, 90 degrees of scaption was used instead of 90 degrees of abduction and then the reliability of modified lateral scapular slide test (MLSST) was evaluated. Materials and Methods: Fifteen healthy overhead sport-men, aged 20 to 40, were recruited in the study. The minimal vertical distance between inferior angle of scapula and spinous process of T7 was measured by two examiners in one session and by one examiner in the next week using a caliper in neutral position (arm is relaxed at the side), 90 degrees of scaption and 180 degrees of elevation.Results: Reliability in neutral position was maximum (ICC 0.83 to 0.97, good to high). In 90 degrees of scaption, inter-rater and intra-rater reliability were 0.70 to 0.75 and 0.65 to 0.83, respectively. In 180 degrees of elevation, inter-rater reliability was 0.58 and intra-rater reliability was 0.84 to 0.89. Conclusion: 90 degrees of Scaption and 180 degrees of elevation, as a functional position in the athletes, may be used as choice positions in lateral scapular slide test

Deficit in neuromotor control of the core may be a remote contributing factor to the development of PFPS. Comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(PFPS) in a stair stepping task is the aim of this study. Methods : In this non-randomized interventional study fifteen males with PFPS and fifteen asymptomatic controls participated. Electromyographic(EMG) activity of Vastusmedialisobliquus(VMO),Vastuslateralis(VL), Gluteus medius (GMED),Gluteus Maximus (GMAX),Internal oblique (IO) and Erector spinae (ES) were recorded and EMG onsets were assessed in both stepping up (SU) and down (SD).The time of foot contact determined by a foot switch. Results: During SU:Onset times of all muscles except, VL and ES in the controls were significantly less than PFPS group (P < 0.05). In PFPS group ...
