STUDY DESIGN A clinical trial comparing a back pain group with a pain-free group. OBJECTIVES To investigate whether proprioceptive deficits existed in a group of individuals reporting low back pain. SUMMARY OF BACKGROUND DATA Little work has so far been conducted on the measurement of proprioception in the spine. Those studies that have been carried(More)
BACKGROUND Quadriceps atrophy is a commonly cited accompaniment to patellofemoral pain syndrome (PFPS), yet there is little valid, objective evidence for its existence. OBJECTIVE To investigate atrophy and weakness of the quadriceps femoris muscle group in patients with PFPS using measures of cross-sectional area and peak extension torque. METHODS A(More)
This study aimed to examine within-day and between-days intratester reliability of mechanomyography (MMG) in assessing muscle fatigue. An accelerometer was used to detect the MMG signal from rectus femoris. Thirty one healthy subjects (15 males) with no prior knee problems initially performed three maximum voluntary contractions (MVCs) using an ISOCOM(More)
BACKGROUND McConnell recommended that patellar tape be kept on all day, until patients learn how to activate their vastus medialis obliquus (VMO) during an exercise program. This application may pose problems because prolonged taping may be inadvisable for some patients or even contraindicated owing to skin discomfort, irritation, or allergic reaction. (More)
Patients with knee osteoarthritis have both poor strength and endurance of their quadriceps muscles. It is possible to assess muscle fatigue by monitoring frequency spectrum using electromyography (EMG). This study used the closed kinetic chain approach to muscle assessment. Fifty-five subjects with knee osteoarthritis were examined twice within 1 week. To(More)
OBJECTIVE IA steroid injections (IASIs) have been shown to relieve pain in knee OA and are widely used in clinical practice. There is, however, evidence of some variation in response. Knowledge of predictors of response could aid in the selection of patients for this therapy. The aim of this systematic review was to determine factors associated with(More)
OBJECTIVES The knee can be injected at different anatomic sites with or without image-guidance. We undertook a systematic review to determine the accuracy of intra-articular knee injection (IAKI) and whether this varied by site, use of image-guidance, and experience of injectors, and whether accuracy of injection, site, or use of image-guidance influenced(More)
The aim of this study was to assess the effect of patellar taping of the proprioceptive status of patients with patellofemoral pain syndrome (PFPS). A total of 32 subjects (18 males, 14 females of age 31.9 +/- 11.2, body mass index 25.8 +/- 5.3) with PFPS were tested for Joint Position Sense (JPS) using a Biodex dynamometer. Outcomes of interest were the(More)
OBJECTIVE To evaluate the effects of pulsed shortwave on osteoarthritis of the knee. METHODS A double blinded, randomised, controlled trial. Thirteen female and 14 male patients with radiographic evidence of knee osteoarthritis were randomly allocated to either low dose (10 W), or high dose (20 W) or placebo high frequency pulsed shortwave. Knee(More)
Massage has been a therapeutic modality in all cultures since early civilization and has had a long tradition of use in the sporting context. However, there has been a paucity of scientific evidence of the physiological, psychological and therapeutic effects of commonly used massage techniques. This paper reviews the early and more recent studies on the(More)
