Abstract

Study Design Descriptive, laboratory-based, cross-sectional study. Objectives To describe scapular musculature strength, endurance, and change in thickness in individuals with unilateral lateral epicondylalgia (LE) compared to the uninvolved limb and the corresponding limb of a matched comparison group. Background Reported poor long-term outcomes for the nonsurgical management of individuals with LE suggest a less-than-optimal rehabilitation process. Knowledge of scapular muscle function in a working population of individuals with LE may help to further refine conservative management of this condition. Methods Twenty-eight patients with symptomatic LE and 28 controls matched by age and sex were recruited to participate in the study. Strength of the middle trapezius (MT), lower trapezius (LT), and serratus anterior (SA) was measured with a handheld dynamometer. A scapular isometric muscle endurance task was performed in prone. Changes in muscle thickness of the SA and LT were measured with ultrasound imaging. Analysis-of-variance models were used to determine within- and between-group differences. Results The involved side of the group with LE had significantly lower values for MT strength (P = .031), SA strength (P<.001), LT strength (P = .006), endurance (P = .003), and change in SA thickness (P = .028) when compared to the corresponding limb of the control group. The involved side of the group with LE had significantly lower strength of the LT (P = .023) and SA (P = .016) when compared to the uninvolved limb; however, these differences were small and of potentially limited clinical significance. Conclusion When compared to a matched comparison group, there were impairments of scapular musculature strength and endurance in patients with LE, suggesting that the scapular musculature should be assessed and potentially treated in this population. Cause and effect cannot be established, as the weakness of the scapular musculature could be a result of LE. J Orthop Sports Phys Ther 2015;45(5):414-424.

Comportamiento escapular en individuos con epicondilitis

El tratamiento conservador de los individuos con epicondilalgia lateral está asociado desafortunadamente con pobres resultados a largo plazo, sugiriendo un proceso recuperador por debajo de lo óptimo. Se ha postulado durante algún tiempo que la función muscular escapular está correlacionada con los síntomas de la cara lateral del codo. El objetivo del siguiente estudio fue determinar la fuerza muscular escapular, la resistencia y el cambio en grosor entre individuos con epicondilalgia lateral, comparado con el contralateral, así como con el miembro correspondiente del grupo control emparejado.
28 pacientes con epicondilalgia lateral se emparejaron con 28 controles sanos. El lado sintomático del grupo con epicondilalgia tuvo valores significativamente menores de fuerza en el trapecio medio, serrato anterior, trapecio inferior junto con menos resistencia y grosor del serrato anterior comparado con el grupo control. Además, el codo implicado era más débil en el trapecio inferior y serrato anterior comparado con el lado no implicado del grupo con epicondilalgia lateral.
Estos resultados sugieren que la musculatura escapular debe ser valorada y potencialmente tratada en esta población de pacientes con epicondilalgia lateral.
