Abstract

Background Well-established manual/musculoskeletal interventions on the ankle joint are used in addition to diagnosis-orientated mobilisation of the tarsal joints in everyday practice in patients with chronic unstable ankle joint. Diagnosis-oriented manual/ musculoskeletal intervention means to perform a mobilisation in the talocrural joint and the tarsal joints with existing restrictions. However, this approach is lacking in research settings. In this context only the talocrural joint is mobilised. The procedure of diagnosis-oriented mobilisation in the talocrural joint and the tarsal joints in which restrictions exist are not taken into account. Objective The primary aim of this pilot study is the presentation of the feasibility of the recruitment process, adherence and the safety of the investigation process and investigation. The secondary aim is the evaluation of nine mobilisations in the talocrural joint and mobilisations of the tarsal joints in which restrictions exists on postural control and muscle activation of the flexor muscles and thigh muscles in patients with chronic ankle instability (CAI) for four weeks. Method This cross-over-design will recruit, include and evaluate a minimum of 30 patients with CAI. Cross-over effects will be assessed using L-Statistic of Puri & Sen. To analyse treatment effects and periodic effects the non-parametric Wilcoxon Rank Sum test will be used. Conclusions It is assumed that selective mobilisation of the talocrural joint as well as of the tarsal joints with existing restrictions improve muscle activity and postural control of the affected leg in patient with chronic unstable ankle joint.
