Patients received either a single 30-second bout of grade III AP talocrural joint mobilization or no intervention and were assessed after the first 24 hours. A single bout of AP talocrural joint mobilizations was revealed to have no immediate effect on ankle dorsiflexion range of motion (ROM), posterior talar translation, or self-reported function; however, an immediate effect on pain perception was observed.

El Índice de Fragilidad es una herramienta que ayuda en la interpretación de hallazgos significativos, proporcionando una medida de fuerza para un resultado. El Índice de Fragilidad representa el número de eventos consecutivos que es necesario añadir a un resultado dicotómico para que el hallazgo deje de ser significativo. Un número pequeño representa un hallazgo más débil y un número grande un hallazgo más fuerte.
¿Por qué se necesitaba ahora este estudio?
Following a lateral ankle sprain, it has been reported that individuals may experience decreased dorsiflexion ROM and posterior talar glide. While these individuals may benefit from joint mobilization, there has been no previous study evaluating the use of anterior to posterior (AP) talocrural joint mobilizations in patients with acute lateral ankle sprains. Thus, this study aimed to investigate the immediate effects of a single bout of grade III AP talocrural joint mobilization on ankle dorsiflexion ROM, posterior talar translation, and self-reported pain and function in these patients.
¿Cuál era la pregunta principal de la investigación?
Did a single bout of AP talocrural joint mobilization lead to better ankle dorsiflexion ROM, posterior talar translation, and self-reported pain and function, compared to no intervention, in acute lateral ankle sprains when assessed after the first 24 hours?
¿Cuáles fueron los hallazgos importantes?
- In regard to dorsiflexion ROM, there was not a significant group by time interaction (F2,30 = 0.17, P = 0.85, 1-beta = 0.07) or group main effect (F2, 30 = 0.21, P = 0.66, 1-beta = 0.07); however, there was a significant main effect for time (F2,30 = 3.67, P = 0.04, 1-beta = 0.63).
- While there was a significant improvement in dorsiflexion ROM from baseline to 24 hour follow-up (P=0•037), there was no significant difference between the treatment (6.49 (SD 6.43) to 8.82 (SD 7.29)) and control (7.36 (SD 6.38) to 9.94 (SD 4.02)) groups (P > 0.05).
- There was no significant difference (P > 0.05) regarding posterior talar translation measures between the treatment (7.09 (SD 3.54) to 7.06 (SD 2.99)) and control (5.86 (SD 2.81) to 6.95 (SD 3.64)) groups from baseline to the 24 hour follow-up. No significant group by time interaction (F2,30= 0.58, P = 0.57, 1-beta = 0.14), group main effect (F2,30 = 0.45, P = 0.51, 1-beta = 0.10), or time main effect (F2,30 = 0.86, P = 0.43, 1-beta = 0.18) were seen.
- In respect to the FADI-ADL and FADI-sport, there were no significant group by time interactions (F1,15 = 0.43, P = 0.52, 1-beta = 0.09; F1,15 = 0.04, P = 0.84, 1-beta = 0.05, respectively) or group main effects (F1,15 = 1.51, P = 0.24, 1-beta = 0.21; F1,15 = 0.00, P = 0.99, 1-beta = 0.05).
- The treatment group demonstrated a 20% reduction in pain (t8 = -3.74, P = 0.006) at the 24 hour follow-up when compared to the control group (t7 = 0.00, P = 1.0).
¿Qué es lo que más debo recordar?
A single bout of AP talocrural joint mobilization for acute ankle sprains displayed no effect in increasing ankle dorsiflexion ROM, decreasing posterior talar glide, or improving self-reported function. However, individuals receiving joint mobilization demonstrated decreased pain compared to those who did not receive the intervention.
¿Cómo afectará esto al cuidado de mis pacientes?
This study suggests that joint mobilization provides no apparent benefit in ankle dorsiflexion ROM, posterior talar translation, or self-reported function when treating acute lateral ankle sprains. However, there may be a positive benefit in terms of pain perception immediately following treatment. Future research is required to investigate the long-term effects of multiple applications of joint mobilizations.
