Effects of two mobilization with movement techniques to the talocrural joint in individuals with dorsiflexion limitation: clinician vs self-applied

Abstract

Introduction: Dorsiflexion (DF) range of motion (ROM) limitation is a risk factor for many injuries. Many interventions are applied to individuals with DF limitation to increase DF-ROM. Purpose: To investigate the effects of single-session Clinician and Self-applied Mobilization with Movement (C-MWM and S-MWM) methods on DF-ROM, balance, and jump. Methods: The Weight Bearing Lunge Test was used to assess DF-ROM. Individuals with DF-ROM below 45 degrees were defined as having DF limitation. Forty-eight individuals were randomly assigned to C-MWM, S-MWM, and control groups. Balance was assessed with Y-Balance Test (YBT), and jumping was evaluated by a single-leg countermovement jump test. Clinicians mobilized participants in the C-MWM group, while those in the S-MWM group were mobilized with the help of a non-elastic belt. Those in the control group performed only lunge movements. Results: An increase in DF-ROM was observed in the C-MWM (d = 0.66, p = .001) and S-MWM groups (d = 0.53, p = .001). In YBT, anterior (C-MWM: d = 0.53, p = .001; S-MWM: d = 0.47, p = .028), posteromedial (C-MWM: d = 0.44, p = .023; S-MWM: d = 0.40, p = .011), and composite scores (C-MWM: d = 0.65, p = .004; S-MWM: d = 0.32, p = .013) improved in C-MWM and S-MWM groups. There was no significant difference in the posterolateral direction in all groups (p > .05). In the control group, there was a change only in composite score (d = 0.38, p = .016). There was no change in a jump in three groups (p > .05). When the gains obtained in groups were compared, it was observed that the gains in all parameters were similar (p > .05). Conclusion: When it is desired to increase DF-ROM and improve balance in individuals with DF limitation, the clinician or self can apply MWM to the talocrural joint.
