Effectiveness of three modes of kinetic-chain exercises on quadriceps muscle strength and thigh girth among individuals with knee osteoarthritis

Abstract

BackgroundThe study was designed to evaluate and compare the effectiveness of 12-week open, closed and combined kinetic-chain exercises (OKCE, CKCE and CCE) on quadriceps muscle strength and thigh girth of patients with knee osteoarthritis (OA).MethodThe randomized clinical trial involved ninety-six consecutive patients with knee OA who were randomly assigned to one of OKCE, CKCE or CCE groups. Participants’ static quadriceps muscle strength (SQS), dynamic quadriceps muscle strength (DQS) and thigh girth (TG) were assessed using cable tensiometer, one repetition method and inelastic tape measure respectively at baseline and at the end of weeks 4, 8 and 12 of study.ResultsThe three groups were comparable regarding their demographic and dependent variables at baseline; there was significant time effect (p < 0.001each) as all three measures significantly increased over time from baseline to week 12 [mean difference: SQS: 3.30 (95% CI: 2.52–4.08) N; DQS: 0.74 (95% CI: 0.45–1.02) N; TG: 1.32 (95% CI: 0.93–1.71) cm]. The effect of intervention-time interaction was not significant (p > 0.05) for all three measures. Changes in SQS, DQS and TG between baseline and week 12 were also not significantly different (p > 0.05) among the three groups.ConclusionAll three exercise regimens are effective and demonstrate similar effects on quadriceps muscle strength and muscular trophism.Trial registration NHREC/05/01/2008a.

Wireless Motion Sensors—Useful in Assessing the Effectiveness of Physiotherapeutic Methods Used in Patients with Knee Osteoarthritis—Preliminary Report

“…The literature search yielded no studies citing the use of this parameter in relation to specific disease entities. We employed the described methods in clinical practice because OAK patients develop a number of undesirable anatomical changes that negatively affect the knee joint position sense [27,40,41] and cause pain [21,26] and functional deficits [2,3,7,12,30]. Therefore, based on available data from other studies [27,42], we determined that the treatment algorithm for OAK patients should include therapeutic procedures that improve joint position sense and overall function while reducing pain intensity.…”

“…One such procedure, often used to manage OAK patients, is a closed kinematic chain synergistic exercise regimen for the lower limb [27,35,41]. This therapeutic procedure is characterized by direct contact of the lower limbs with the ground or exercise equipment during the therapeutic session.…”

Effect of self-management education versus quadriceps strengthening exercises on pain and function in patients with knee osteoarthritis

“…Volunteers with knee OA who also had severe/uncontrolled comorbidities (such as hypertension, diabetes, kidney failure, psychiatric disorders) or a neurological condition affecting the lower limb (such as post-stroke muscle weakness or poliomyelitis), as well as those unable to walk were excluded from the study [26,27]. The total of 79 participants (66 females, 13 males) were randomized to 2 groups by having them pick a wrapped paper with A or B letter with the tag number between 1 and 100 (computer-generated random numbers) written on it from an opaque envelope.…”

“…A plastic weight (W) corresponding to a certain rM of the participant was randomly selected and attached via the DeLorme's boot to the participant's foot. After a warm-up with a set of 10 lifts with a lighter weight, using the method described by Olagbegi et al [27], the subjects lifted the weight r times until volitional exhaustion. The participants' 1-rM was determined with Brzycki predictive equation:…”
