2 Clinical Trials for Various Conditions
Our objective was to determine if an ultrasound guided ACB can preserve quadriceps strength, thus minimizing weakness of knee extension compared with ultrasound guided femoral nerve block. Our primary outcome was the percent of maximum voluntary isometric contraction (MVIC) of knee extension preserved at 30 mins after either an ACB or FNB. Secondary outcomes included MVIC of knee extension at 60 min, hip adduction at 30 and 60 mins, and assessment of fall risk with the Berg Balance Scale (BBS) at 30 minutes.
The goal of this trial was to determine if a mid-thoracic high velocity low amplitude spinal manipulation improves force output in those with unilateral hip adductor weakness. The main aims were to determine if the intervention: Improved hip adductor force and muscle activation immediately and 48 h post manipulation compared to a control group. Improved gluteus maximus and latissimus dorsi force and muscle activation immediately and 48 h post manipulation compared to a control group. Strength and muscle activation of the hip adductors, hip extensors (gluteus maximus), and shoulder extensors (latissimus dorsi) were measured prior to, immediate after, and 48 hours after receiving a high velocity low amplitude manipulation to the thoracic spine. The manipulation was performed by a licensed chiropractor. A control group received a validated sham manipulation to the thoracic spine. Participants were blinded to group assignment.
