The results also indicate that 10 minutes static lumbar flexion will produce relaxation of the erector spinae muscles later during the forward bending activity and earlier reactivation during the extension (P<0.05). In other words, KT increased flexion relaxation time in erector spinae muscles (P<0.05). Results: The results indicate that KT causes erector spinae muscles relaxation earlier in the flexion and later reactivated in the extension. The surface electromyographic silence and onset of the erector spinae muscle activities were measured in two states before the static lumbar flexion and 10 minutes after the static lumbar flexion in two conditions (with and without KT). Methods: The research was conducted on 22 healthy female college students. This study investigated the effects of Kinesio taping (KT) before and after periods of the static lumbar flexion on the timing of FRP for the erector spinae muscles. Laxity in the passive tissues of the spine during prolonged spinal flexion disturbs the spinal stability.

During a short static lumbar flexion, significant changes are elicited in the muscular activity pattern of the FRP. Static lumbar flexion under constant displacement or load, within the physiological range, elicits creep in lumbar viscoelastic tissues. FRP is a shift in load sharing and spinal stabilization from active structures (erector spinae muscles) to passive ligamentous and articular structures.

Purpose: In approaching full trunk flexion (75%-80% of full flexion), myoelectric activity of lumbar erector spinae muscles is reduced or silenced this response is known as flexion-relaxation phenomenon (FRP).
