Abstract
Background
Although manual therapy is an effective technique for increasing ankle range of motion, the dose-response required is unclear.
Objective
To find out what number of sessions of talus mobilizations will induce a detectable change in weight bearing ankle dorsiflexion range of motion of older adults with limited ankle mobility.
Design
Four-arm randomized clinical trial.
Setting
Community-dwelling.
Methods
62 older adults; aged over 60; with ankle dorsiflexion ROM below 35°. Four groups received from one to four treatment sessions. Each session consisted of 3 mobilizations of 30 s, with of the talus in anteroposterior glide, with a rest of 30 s. Grade IV mobilizations were applied to target the accessory movement of the ankle up to the resistance offered by periarticular tissues. The Lunge test was used to measure weight bearing ankle dorsiflexion.
Results
The four groups increased their ankle mobility after one session, but two sessions were needed to overcome the established 4.7°’ threshold, regardless of group. Only those participants who received four sessions maintained the improvements for 8 weeks.
Conclusions
Two sessions of talus mobilizations are effective in improving weight bearing ankle dorsiflexion ROM. It will be necessary to deliver four sessions of treatment if these improvements are to be maintained for at least 8 weeks.
期刊介绍：
The International Journal of Osteopathic Medicine is a peer-reviewed journal that provides for the publication of high quality research articles and review papers that are as broad as the many disciplines that influence and underpin the principles and practice of osteopathic medicine. Particular emphasis is given to basic science research, clinical epidemiology and health social science in relation to osteopathy and neuromusculoskeletal medicine.
The Editorial Board encourages submission of articles based on both quantitative and qualitative research designs. The Editorial Board also aims to provide a forum for discourse and debate on any aspect of osteopathy and neuromusculoskeletal medicine with the aim of critically evaluating existing practices in regard to the diagnosis, treatment and management of patients with neuromusculoskeletal disorders and somatic dysfunction. All manuscripts submitted to the IJOM are subject to a blinded review process. The categories currently available for publication include reports of original research, review papers, commentaries and articles related to clinical practice, including case reports. Further details can be found in the IJOM Instructions for Authors. Manuscripts are accepted for publication with the understanding that no substantial part has been, or will be published elsewhere.
