Context
Limited ankle mobility describes reduced range of motion in the ankle joint — restricted dorsiflexion (ability to bring the foot toward the shin), plantarflexion, inversion, or eversion. It is common following ankle sprains (where scar tissue and guarding reduce mobility), in those with chronic ankle instability, and as a consequence of prolonged sitting, tight calf muscles, or ankle arthritis. Limited dorsiflexion specifically affects functional movement patterns — squatting, walking uphill, stair climbing — and is increasingly recognised as contributing to knee, hip, and lower back pain through compensatory movement patterns. Calf stretching (particularly gastrocnemius and soleus), ankle circles, and specific dorsiflexion mobilisation exercises restore range of motion effectively. Physiotherapy assessment identifies whether restriction is joint or soft tissue in origin, guiding targeted intervention.
The Evidence
What research and clinical practice say about limited ankle mobility and approaches to restoring range of motion.
Well-supported by clinical practice and biomechanical research
Limited ankle mobility is a recognised musculoskeletal issue with a solid evidence base supporting targeted stretching, mobilisation, and physiotherapy. Restricted dorsiflexion in particular is linked to compensatory movement patterns affecting the knee, hip, and lower back.
Sudden loss of ankle mobility, inability to bear weight, joint swelling with redness and heat, or symptoms following a fall or trauma should be assessed by a qualified health professional promptly. Progressive weakness or loss of function also warrants professional evaluation. Do not attempt mobility exercises if any of these are present.
Research supports calf stretching — targeting both gastrocnemius and soleus — and specific dorsiflexion mobilisation exercises for improving ankle range of motion. Evidence is moderate in quality overall. Physiotherapy-guided assessment helps distinguish joint-origin from soft-tissue restriction, which influences which approach is most appropriate.
Limited dorsiflexion influences squatting mechanics, stair climbing, and walking on inclines. It is increasingly recognised as contributing to knee, hip, and lower back loading through compensatory movement. Common causes include post-sprain scar tissue, chronic ankle instability, prolonged sitting, tight calf muscles, and ankle arthritis.
Physiotherapy, yoga, and targeted mobility exercise programmes are commonly used. Physiotherapy offers structured assessment and exercise prescription. Yoga and movement practices may support flexibility and body awareness. Complementary approaches can be used alongside — not instead of — professional assessment where restriction is significant or persistent.
If ankle mobility has not improved with self-directed stretching, or if restriction is affecting daily function, a physiotherapy assessment is worthwhile. Identifying the source of restriction guides more targeted intervention. This is particularly relevant following ankle sprains, where scar tissue and guarding are common contributors.
Much of the research on ankle mobility interventions involves small samples or short follow-up periods. Individual causes of restriction vary considerably, meaning self-directed programmes may not address the underlying issue.
