Joint Position Sense (joint + position_sense)
Selected AbstractsRetraining cervical joint position sense: The effect of two exercise regimesJOURNAL OF ORTHOPAEDIC RESEARCH, Issue 3 2007Gwendolen Jull Abstract This study compared the effects of conventional proprioceptive training and craniocervical flexion (C-CF) training on cervical joint position error (JPE) in people with persistent neck pain. The aim was to evaluate whether proprioceptive training was superior in improving proprioceptive acuity compared to another form of exercise, which has been shown to be effective in reducing neck pain. This may help to differentiate the mechanisms of effect of such interventions. Sixty-four female subjects with persistent neck pain and deficits in JPE were randomized into two exercise groups: proprioceptive training or C-CF training. Exercise regimes were conducted over a 6-week period, and all patients received personal instruction by an experienced physiotherapist once per week. A significant pre- to postintervention decrease in JPE, neck pain intensity, and perceived disability was identified for both the proprioceptive training group (p,<,0.001) and the C-CF training group (p,<,0.05). Patients who participated in the proprioceptive training demonstrated a greater reduction in JPE from right rotation compared to the C-CF training group (p,<,0.05). No other significant differences were observed between the two groups. The results demonstrated that both proprioceptive training and C-CF training have a demonstrable benefit on impaired cervical JPE in people with neck pain, with marginally more benefit gained from proprioceptive training. The results suggest that improved proprioceptive acuity following intervention with either exercise protocol may occur through an improved quality of cervical afferent input or by addressing input through direct training of relocation sense. © 2006 Orthopaedic Research Society.

J Orthop Res 2007 [source] Do hypermobile subjects without pain have alteration to the feedback mechanisms controlling the shoulder girdle?MUSCULOSKELETAL CARE, Issue 3 2010H.M. Jeremiah BSc (Hons), MMACP Abstract Objectives:,It has been reported that hypermobile subjects have proprioceptive deficits. However, it remains unclear whether pain-free subjects with hypermobility also have deficits. Methods:,Ten subjects with hypermobility and nine without hypermobility were recruited following ethical approval and informed consent. Shoulder mobility, joint position sense (JPS) and a reflex of trapezius evoked from arm afferents were compared. Results:,There was greater shoulder mobility in the hypermobile group (p = 0.004). There were no differences in shoulder JPS between the groups (p = 0.27), although, the hypermobile group displayed a larger degree of variability (p = 0.014). Finally, there were no differences in the latency of upper and lower trapezius reflexes evoked from arm afferents (p = 0.86 and 0.98, respectively). Conclusions:,In a group of people with hypermobility without shoulder problems, there was no difference in either shoulder JPS or reflex latency when compared with a non- hypermobile group. The relevance of pain to proprioceptive deficits is discussed. © 2010 John Wiley & Sons, Ltd. [source] Repeatability of joint proprioception and muscle torque assessment in healthy children and in children diagnosed with hypermobility syndromeMUSCULOSKELETAL CARE, Issue 2 2008Francis A. Fatoye MSc Abstract Background:,Impairment of joint proprioception in patients with hypermobility syndrome (HMS) has been well documented. Both joint proprioception and muscle torque are commonly assessed in patients with musculoskeletal complaints. It is unknown, however, if these measures change significantly on repeated application in healthy children and in children with HMS. Aim:,To investigate the between-days repeatability of joint proprioception and muscle torque in these groups. Methods:,Twenty children (10 healthy and 10 with HMS), aged eight to 15 years, were assessed on two separate occasions (one week apart) for joint kinaesthesia (JK), joint position sense (JPS), and the extensor and knee flexor muscle torque of the knee. JK was measured using threshold to detection of passive movement. JPS was measured using the absolute angular error (AAE; the absolute difference between the target and perceived angles). Knee extensor and flexor muscle torque was normalized to body weight. Results:,Intra-class correlation coefficients (ICC) for JK, extensor and flexor muscle torque were excellent in both groups (range 0.83 to 0.98). However, ICC values for JPS tests were poor to moderate in the two groups (range 0.18 to 0.56). 95% limits of agreement (LOA) were narrow in both cohorts for JK and muscle torque (indicating low systematic error) but wide for the JPS tests. 95% LOA also demonstrated that the measuring instruments used in this study had low between-days systematic error. Conclusions:,Based on ICC and 95% LOA, the repeatability of JK and muscle torque measurements was excellent in both healthy children and those with HMS. The JPS test can only be assessed with poor to moderate repeatability. The use of the JPS test in these children should be undertaken with caution. Copyright © 2008 John Wiley & Sons, Ltd. [source] Trials needed to assess knee proprioception following strokePHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 1 2009Pagamas Piriyaprasarth Abstract Background and Purpose.,This study explores the number of trials required to identify clinically significant impairments in knee joint position sense and movement sense following stroke.,Method.,Proprioception was assessed in 33 stroke patients aged 37,87 years. Ten trials for each assessment were performed in sitting and supine positions using both verbal response techniques and contralateral limb matching.,Results.,Forty-six percent of participants were identified with a proprioceptive deficit. The trial where the first incorrect response occurred varied across individuals and testing positions. Performing only one trial detected proprioceptive impairments in less than 10% patients, and incorrect responses did not always occur in the first 5 trials. In sitting, no participant failed the assessment of knee joint position sense using the verbal response technique after only 6 trials. In supine, no participant failed the assessment of knee movement sense using the verbal response technique after only 6 trials. For the assessment of knee joint position sense in sitting using contralateral limb matching an estimated 9.4% of patients with a deficit would be missed if only 3 trials were used in preference to 5. For assessment of knee joint position sense in sitting, an estimated 18.8% of patients with deficits would be missed if only 3 trials were used rather than 10 trials.,Conclusions.,Clinicians should perform at least 10 trials in either sitting or supine to quantify joint position sense and movement sense at the knee following stroke.
