“…We aimed to include 25 participants with AKP. This sample size was calculated using a pragmatic approach and based on previous studies (Akseki et al 2008 ; Baker et al 2002 ; Cyrillo & Cabral 2014 ; Guney et al 2015 ).…”

“…However, in these studies (Akseki et al 2008 ; Baker et al 2002 ; Cyrillo & Cabral 2014 ; Guney et al 2015 ) participants presented with a mean duration of symptoms ranging from 3 to 36 months, indicating sub-acute ongoing chronic pain. Two of the studies focused on females only (Cyrillo & Cabral 2014 ; Guney et al 2015 ) and one study (Guney et al 2015 ) required participants to present with at least moderate pain levels (more than 4/10) that were present daily for at least a month.…”

“…Previous studies in this field reported no significant differences in JPS between individuals with and without AKP (Bennell et al 2005;Naseri & Pourkazemi 2012;Yosmaoglu et al 2013). In contrast, other studies have observed that JPS is significantly impaired in individuals with AKP compared with controls (Akseki et al 2008;Baker et al 2002;Cyrillo & Cabral 2014;Guney et al 2015). The reasons for these conflicting findings are unknown and although all these studies measured JPS, different methods for measuring JPS were used.…”

“…Altered proprioception has been documented in patients with AKP (Akseki et al 2008 ; Baker et al 2002 ; Cyrillo & Cabral 2014 ; Guney et al 2015 ). Proprioception is ‘the use of joint position sense (JPS) and joint motion sense to respond to stresses placed upon the body by alteration of posture and movement’ (Norris 2011 ).…”

“…The reasons for these conflicting findings are unknown and although all these studies measured JPS, different methods for measuring JPS were used. These methods included: (1) image recorded where photography is used to assess knee joint angles (Baker et al 2002 ; Naseri & Pourkazemi 2012 ), (2) electro-goniometry with knee angular error (Akseki et al 2008 ; Cyrillo & Cabral 2014 ), (3) dynamometry (Guney et al 2015 ) and (4) a functional loaded squat system (Yosmaoglu et al 2013 ).…”

Background: Anterior knee pain (AKP) commonly affects both physically active and sedentary individuals and the aetiology is unknown. Altered joint position sense (JPS) impacts accurate motor action and knee joint stability. It is unclear whether people with AKP have altered JPS.Objective: The aim of our study was to investigate JPS in the knees of individuals with AKP.Method: A descriptive cross-sectional study measured JPS in 25 participants with unilateral or bilateral AKP. JPS was measured using active JPS testing during single leg squat (SLS) and active knee extension (AKE) in sitting. Target angles (TA) were self-determined based on each participant’s capabilities. The absolute error (AE) was the main outcome measure. Impaired JPS was classified as an AE equal to or greater than five degrees.Results: There were no significant differences in JPS when comparing the affected and unaffected knees in participants with AKP (p 0.05). However, a subgroup of participants with altered knee JPS was identified. There was a tendency towards greater knee flexion in the TAs of knees without AKP.Conclusion: Our results showed that JPS is not significantly more impaired in knees with AKP compared with knees without AKP in a group of individuals with AKP. A subgroup with altered JPS in knees with and without AKP was identified. This finding could be because of compensatory gait patterns and the precision of the Vicon 3D motion analysis system.Clinical implications: Joint position sense should be assessed bilaterally in individuals with AKP.

Purpose: : to evaluate the reliability and validity of computer-aided design (Autocad) software in assessing knee position sense in participants with (PFP) against an isokinetic-dynamometer (IKD) procedure.. Methods: Cross-sectional, validity and reliability study in Isokinetic laboratory. Thirty-nine participants (11 males and 28 females) ranging in age from 18 to 35 years old participated in the study. On two separate occasions, two days apart, all subjects were evaluated by the same examiner. Knee joint position sense by isokinetic dynamometer (IKD) and Autocad software at angle 20º and 60º. Intratester reliability was obtained by intraclass correlation coefficient (ICC) and standard error of measurement (SEM).. Results: Validity was determined using the Pearson product-moment relationship, which revealed a moderate to good association (0.60) between the isokinetic dynamometer (IKD) and computer-aided design software at 20º and a good to excellent association (0.79) at 60º. Intrarater reliability coefficients (ICC) were (0.64) at 20º and (0.50) at 60º, indicating a moderate to good association at both angles with a standard error of measurement of (2.2) degree at 20º and (2.9) degree at 60º. Conclusion: computer-aided design software had high accuracy, a low exam cost, and not involves radiation exposure. These findings support using this method for examining joint position sense. Therefore, Therapist does not need expensive methods to obtain representative JPS abilities.

Background: Patellofemoral pain syndrome is a common, painful musculoskeletal condition that affects physically active young adults and adolescents. During assessment of joint position sense, the different positions of the knee may affect the internal structures of the knee differently. Therefore, examining the differences in the two positions between both males and females may shed light on the effect of muscle activation. Aim of Study: To examine the differences between 20 and 60 angles of knee extension on knee joint position sense as well as to examine the differences in knee joint position sense between males and females in patient with patellofemoral pain syndrome. Material and Methods: Thirty nine participants (11 men, 28 women) participated in this study. With a mean age of 18 to 35 years with mean age (24.25±3.40) years, mean weight (68.71 ± 16.01) Kg, and mean height (164.07± 10. 14) cm. All subjects were assessed by the same examiner via the Isokinetic Dynamometer Device (IKD) at angles 20º and 60º with angular velocity 2º/sec to determine which angle has more angular error. Results: The results revealed that the 20 angle position had a significantly greater absolute reposition error than the 60 angle position (p=0.039). There was no significant difference in joint position sense between males and females at angle 20 (p=0.829), and angle 60 (p=0.833). Conclusion: The results indicate that there is a significant difference in knee joint position sense between position of 20 degrees of extension and 60 degrees of extension. Specifically, as the knee becomes more extended proprioceptive acuity was heightened. Therefore, future research is still needed to discern exactly whether the heightened proprioceptive acuity comes from the differences in gravitational torque or the differences in the anatomical structures of the knee between the two positions.
