Abstract
Objectives: To determine and compare the level of quadriceps activation for knee injured participants during, kinetic open-chain, closed-chain and composite-chain (Slackline) clinical exercises. Quadriceps, activation is a critical component of lower limb movement and subsequently, rehabilitation. However, selective activation can be difficult due to pain, loss of function and impaired neuro-motor activation., Design:, Repeated measures (within-subjects) ANOVA. Methods, Consecutive physiotherapy outpatients (n = 49, 41.8+/-16.8 years, range 13-72 years, 57% female) with, an acute (less than 2 weeks) knee injury were recruited. Participants were assessed for quadriceps activation, using skin mounted electromyography during five separate clinical quadriceps activation exercises:, two open-chain, inner range quads and straight leg raise; two closed-chain, step down and step up; and, a composite-chain, slacklining step-up. Outcome measures were: median score on electromyography as, measured in microvolts (µV); and perceived exertion on an 11-point numerical rating scale. Results:, Median scores of the open- and closed-chain exercises showed no statistical difference, while, composite-chain Slackline exercise showed significantly (p less than 0.0001) higher quadriceps activation, (F(2.52, 121.00) = 21.53, p less than 0.0001) at significantly lower exertion (F(1.62, 77.70) = 26.88, p less than 0.0001)., Conclusions:, The use of Slackline rehabilitation training can provide significant increases in activation and, recruitment of the quadriceps for composite-chain exercises in the clinical setting. This activation, occurs spontaneously at significantly lower levels of perceived exertion. This spontaneous quadriceps, activation in a selective and simple manner is a valuable adjunct exercise for lower limb rehabilitation, programs. This is of particular relevance for the outpatient setting and circumstances where the, quadriceps is inhibited and activation is required.
