2021, Article / Letter to editor (BMC Sports Science, Medicine and Rehabilitation, vol. 13, iss. 1, (2021), pp. 122)BACKGROUND: The therapeutic alliance (TA) is the bond between a patient and a physiotherapist during collaboration on recovery or training. Previous studies focused on the TA between physiotherapists and patients of the general population. Little information exists on whether this is similar in the demanding environment of elite athletes. The aim of this study was to investigate the components of TA between elite athletes and physiotherapists. METHODS: Ten elite athletes and ten physiotherapists were interviewed using one-on-one semi-structured interviews between June 2020 and October 2020. Athletes were included if they competed at national or international championships. Physiotherapists had to treat elite athletes on a regular basis. Interview questions were based on TA components of the general physiotherapy population. The interviews were transcribed and coded using inductive thematic analysis. RESULTS: The analysis resulted in an elite athlete TA framework which consists of nine themes and ten subthemes that could influence the TA. The nine themes are trust, communication, professional bond, social bond, elite athlete, physiotherapist, time, pressure and adversity, and external factors. This showed that the TA consists of bonds on different social levels, depends on the traits of both elite athletes and physiotherapists, and can be positively and negatively influenced by the external environment. The influences from the external environment seem to be more present in the elite athlete TA compared to the TA in the general physiotherapy setting. Multiple relations between themes were discovered. Trust is regarded as the main connecting theme. CONCLUSION: This study provides a framework to better understand the complex reality of the TA between elite athletes and physiotherapists. Compared to the general physiotherapy setting, new themes emerged. The created framework can help elite athletes and physiotherapists to reflect and improve their TA and subsequently improve treatment outcomes.
2020, Article / Letter to editor (Clinical Biomechanics, vol. 80, (2020), pp. 105186)BACKGROUND: In the current study changes in lower-limb motor flexibility of patients undergoing Anterior Cruciate Ligament Reconstruction were evaluated in relation to fear of harm. METHODS: Fourteen patients were measured pre- and post-surgery, and data were compared to those of a single measurement in fifteen controls. Lower-limb motor-flexibility was assessed in treadmill-walking and a cyclic leg-amplitude differentiation task augmented with haptic or visual feedback. Flexibility was captured by determining the between-leg coordination-variability (SD of relative phase) and each leg's temporal variability (sample entropy). Patients were post hoc divided into a higher-fear-group (pre-surgery: n = 6, post-surgery: n = 7) and a lower-fear-group (pre-surgery: n = 6, post-surgery: n = 7) by means of a median split of their scores on a self-reported fear of harm scale. Differences in flexibility-measures between the higher-fear-group and the lower-fear-group were also assessed. FINDINGS: No pre- and post-surgery differences, nor differences with the control group, were found in motor-flexibility during treadmill-walking but the post-surgery higher-fear-group did show lower values of SD relative phase. In the leg-amplitude differentiation task the SD of the relative phase decreased but sample entropy increased post-surgery towards levels of the control-group. The pre-surgery higher-fear-group showed lower values of sample entropy in visual conditions. INTERPRETATION: While gait kinematics may not show motor-flexibility changes following anterior cruciate ligament reconstruction, a leg-amplitude differentiation task does show such changes. Differentiating patients on a fear-of-harm scale revealed subtle differences in motor-flexibility. Challenging patients with non-preferred movements such as amplitude differentiation may be a promising tool to evaluate motor-flexibility following ACLR.
2020, Article / Letter to editor (Human Movement Science, vol. 71, (2020), pp. 102623)Following total knee replacement (TKR), patients often persist in maladaptive motor behavior which they developed before surgery to cope with symptoms of osteoarthritis. An important challenge in physical therapy is to detect, recognize and change such undesired movement behavior. The goal of this study was to measure the differences in clinical status of patients pre-TKR and post-TKR and to investigate if differences in clinical status were accompanied by differences in the patients'' motor flexibility. Eleven TKR participants were measured twice: pre-TKR and post-TKR (twenty weeks after TKR). In order to infer maladaptation, the pre-TKR and post-TKR measurements of the patient group were separately compared to one measurement in a control group of fourteen healthy individuals. Clinical status was measured with the Visual Analogue Scale (VAS) for pain and knee stiffness and the Knee Injury and Osteoarthritis Outcome Score (KOOS). Furthermore, Lower-limb motor flexibility was assessed by means of a treadmill walking task and a leg-amplitude differentiation task (LAD-task) supported by haptic or visual feedback. Motor flexibility was measured by coordination variability (standard deviation (SD) of relative phase between the legs) and temporal variability (sample entropy) of both leg movements. In the TKR-group, the VAS-pain and VAS- stiffness and the subscales of the KOOS significantly decreased after TKR. In treadmill walking, lower-limb motor flexibility did not significantly change after TKR. Between-leg coordination variability was significantly lower post-TKR compared to controls. In the LAD-task, a significant decrease of between-leg coordination variability between pre-TKR and post-TKR was accompanied by a significant increase in temporal variability. Post-TKR-values of lower-limb flexibility approached the values of the control group. The results demonstrate that a clinically relevant change in clinical status, twenty weeks after TKR, is not accompanied by alterations in lower-limb motor flexibility during treadmill walking but is accompanied by changes in motor flexibility towards the level of healthy controls during a LAD-task with visual and haptic feedback. Challenging patients with non-preferred movements such as amplitude differentiation may be a promising tool in clinical assessment of motor flexibility following TKR.
