The effect of spinal manipulation on imbalances in leg strength.
We hypothesized that spinal manipulation (SM) would reduce strength imbalances between legs. Using an unblinded randomized design, 28 males and 21 females (54 ± 19y) with at least a 15% difference in isometric strength between legs for hip flexion, extension, abduction, or knee flexion were randomiz...

Using an unblinded randomized design, 28 males and 21 females (54 ± 19y) with at least a 15% difference in isometric strength between legs for hip flexion, extension, abduction, or knee flexion were randomized to treatment or placebo (mock spinal manipulation). Strength of the stronger and weaker legs for hip flexion, extension, abduction, and/or knee flexion was assessed before and after the intervention. SM reduced the relative strength difference between legs for knee flexion (mean ± SD 57 ± 53 to 5 ± 14%) and hip flexion (24 ± 12 to 11 ± 15%) compared to placebo (34 ± 29 to 24 ± 36%, and 20 ± 18 to 22 ± 26%, respectively) (p = 0.05). SM also improved strength in the weak leg for hip abduction (104 ± 43 to 116 ± 43 Nm) compared to placebo (84 ± 24 to 85 ± 31 Nm) (p = 0.03). This study suggests that spinal manipulation may reduce imbalances in strength between legs for knee and hip flexion. Notre hypothèse est que la manipulation vertébrale (MV) réduirait le déséquilibre entre les jambes. À l'aide d'un essai aléatoire ouvert, 28 hommes et 21 femmes (54 ± 19a) ayant une différence de force isométrique d'au moins 15 % entre les jambes pour la flexion, l'étirement et l'abduction de la hanche, ou la flexion du genou, ont subi de façon aléatoire un traitement réel ou un traitement placebo (manipulation vertébrale simulée). On a alors évalué la force des jambes plus fortes et plus faibles en fonction de la flexion, l'étirement et l'abduction de la hanche, ou la flexion du genou, avant et après l'intervention. La MV a réduit la différence de force entre les jambes quant à la flexion du genou (moyenne ± ET 57 ± 53 à 5 ± 14 %) et la flexion de la hanche (24 ± 12 à 11 ± 15 %) par rapport au traitement placebo (34 ± 29 à 24 ± 36 %, et 20 ± 18 à 22 ± 26 %, respectivement) (p = 0,05). La MV a également amélioré la force de la jambe faible quant à l'abduction de la hanche (104 ± 43 à 116 ± 43 Nm) par rapport au traitement placebo (84 ± 24 à 85 ± 31 Nm) (p = 0,03). Cette étude suggère que la manipulation vertébrale peut réduire le déséquilibre de la force entre les jambes quant à la flexion du genou et de la hanche. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
