Purpose The aims of this study were to (1) investigate the effect of hydrodilatation in frozen shoulder patients on objective indices of shoulder functionality and subjective outcomes of pain, mobility, kinesiophobia, depression, and anxiety, and (2) progress knowledge about the reciprocal temporal relationship between psychological parameters at baseline and objective and subjective outcomes at 3-month follow-up. Methods We evaluated the clinical and psychological status of 72 patients with a frozen shoulder before and after hydrodilatation, using the Constant Murley score, the Visual Analogue score, the Tampa Scale for Kinesiophobia, the Hospital Anxiety and Depression Scale, and the Shoulder Pain And Disability Index. Results We noted a significant improvement in functionality, pain and disability (p < .001). Depression and anxiety improved significantly (p < .001) between baseline and 3-month follow-up. Prospective analyses demonstrated that psychological factors are more likely to predict outcomes of hydrodilatation than vice versa. Conclusion Hydrodilatation followed by physiotherapy is an excellent way to treat patients with recalcitrant frozen shoulder, resulting in a continuous improvement of ROM and pain. Physiotherapists and physicians should be aware that psychological factors might have an impact on the treatment outcome.

Aim: To compare foot joint kinetics and energetics in male paediatric boys with and without blood-induced ankle joint destruction to these of matched control groups. Methods: A cross-sectional study was conducted in which 3D gait analysis data were collected from thirty-five male children (6-21 years) with severe or moderate haemophilia and twenty-six typically developing boys. Structural integrity of the tarsal foot joints of all haemophilic patients was assessed using the IPSG-MRI scale. All participants walked barefoot while adopting a physiological gait pattern. Three subgroups were created based on the IPSG-MRI scores: a group with no joint involvement (HealthyHaemo), with uni-or bilaterally involvement (PathoHaemo) and with only unilaterally involvement (Haemo_Unilateral_Patho). Results: The PathoHaemo group presented a significant lower Lisfranc peak dorsiflexion angular velocity (34.7°/s vs 71.4°/s, P = .000, Cohen d = 1.31) and a significantly higher Lisfranc peak plantarflexion angular velocity (−130.5°/s vs −51.8°/s, P = .000, Cohen d = 0.98) compared to the control group. The Haemo_Unilateral_Patho side had a significant higher Chopart peak dorsiflexion angular velocity compared to the Haemo_Unilateral_Healthy side (41.7°/s vs 31.9°/s, P = .002, Cohen d = 1.16). Conclusion: No evidence for mild and severe gait deviations could be demonstrated. Internal moments, used as a surrogate measure of joint loading, quantified by the multi-segment foot model were found to be similar within the three subanalyses. We suggest that the ongoing musculoskeletal development in children compensates for structural damage to the ankle joint.
