Abstract

PURPOSE:

The purpose of this study was to compare the neuromotor control of the gluteus medius (GMED) and gluteus maximus (GMAX) musclesin runners with Achilles tendinopathy to that of healthy controls.

 PROPÓSITO:
El propósito de este estudio fue comparar el control neuromotor del glúteo medio (GMED) y glúteo mayor (GMAX) en corredores con tendinopatía de Aquiles y la de los controles sanos.

METHODS:

Fourteen male runners with Achilles tendinopathy and 19 healthy male runners (control) ran overground while EMG of GMED and GMAX was recorded. Three temporal variables were identified via visual inspection of EMG data: (i) onset of muscle activity (onset), (ii) offset of muscle activity (offset), and (iii) duration of muscle activity (duration). A multivariate analysis of covariance with between-subject factor of group (Achillestendinopathy, control) and variables of onset, offset, and duration was performed for each muscle. Age, weight, and height were included as covariates, and α level was set at 0.05.

RESULTS:

The Achilles tendinopathy group demonstrated a delay in the activation of the GMED relative to heel strike (P < 0.001) and a shorter duration of activation (P < 0.001) compared to that of the control group. GMED offset time relative to heel strike was not different between the groups (P = 0.063). For GMAX, the Achilles tendinopathy group demonstrated a delay in its onset (P = 0.008), a shorter duration of activation (P = 0.002), and earlier offset (P < 0.001) compared to the control group.

CONCLUSIONS:

This study provides preliminary evidence of altered neuromotor control of the GMED and GMAX muscles in male runners withAchilles tendinopathy. Although further prospective studies are required to discern the causal nature of this relationship, this study highlights the importance of considering neuromotor control of the gluteal muscles in the assessment and management of patients with Achilles tendinopathy.

 CONCLUSIONES:

Este estudio proporciona evidencia preliminar de control de neuromotor alterado de los músculos GMED y GMAX en corredores masculinos con tendinopatía de Aquiles. Aunque se necesitan más estudios prospectivos para discernir la naturaleza causal de esta relación, este estudio pone de relieve la importancia de considerar el control neuromotor de los músculos de los glúteos en la evaluación y tratamiento de pacientes con tendinopatía de Aquiles.
