RESUMEN
INTRODUCTION: Rehabilitation can improve outcomes after reverse shoulder arthroplasty (RSA). However, low adherence to rehabilitation and compliance rates are some of the main barriers. To address this public health issue, the goal of this research was to pilot test and evaluate the effectiveness of a chatbot to promote adherence to home rehabilitation in patients undergoing RSA. METHODS: A randomized pilot trial including patients undergoing RSA and early postoperative rehabilitation was performed. The control group received standard home rehabilitation; the experimental group received the same intervention supervised with a chatbot, with automated interactions that included messages to inform, motivate, and remember the days and exercises for 12 weeks. Compliance with rehabilitation and clinical measures of shoulder function, pain, and quality of life were assessed. RESULTS: 31 patients (17 experimental) with an average age of 70.4 (3.6) completed the intervention. Compliance was higher in the experimental group (77% vs. 65%; OR95% = 2.4 (0.5 to 11.4)). Statistically significant between-group differences with a CI of 95% were found in the QuickDASH questionnaire and self-reported quality of life. No differences were found in the rest of the measures. CONCLUSIONS: This pilot study suggests that the chatbot tool can be useful in promoting compliance with early postoperative home rehabilitation in patients undergoing RSA. Future randomized trials with adequate power are warranted to determine the clinical impact of the proposal.
RESUMEN
PURPOSE: To determine the effectiveness of current strategies oriented to increase adherence to physical therapy in subjects with knee and hip osteoarthritis (OA). MATERIAL AND METHODS: A systematic review of electronic databases was conducted from inception until March 2023. Studies with experimental interventions using strategies to increase adherence to physical therapy programs in subjects with knee or hip OA were included. A meta-analysis compared the effects of such interventions with usual care for adherence-related measures (primary outcome), and functional and pain outcomes, using standardized mean differences (SMD) with a 95% confidence interval (CI). GRADE was used to determine the strength of the resultant evidence and the external validity of the findings. RESULTS: Fifteen articles, assessing 1,818 participants, were included. The interventions included cognitive-behavior strategies, telephone calls, internet-based interventions, communication technologies, and booster sessions. A meta-analysis revealed that the experimental interventions increased adherence over usual care with a moderate effect size of SMD = 0.39 (95%CI = 0.08-0.71) and moderate certainty in this evidence. CONCLUSION: Overall, this review supports that the strategies to promote adherence to physical therapy in individuals with knee and hip OA are effective. However, the positive impact on adherence rates does not always translate into improved clinical outcomes.
Strategies such us behavioral programs, phone reminders, telerehabilitation and equipment based on new technologies can be employed to enhance adherence to physical therapy among individuals with knee and hip osteoarthritis.These interventions may be also beneficial for improving self-reported functionality; however, their impact on performance-based function and pain appears to be limited.The potential for longer-duration interventions to enhance adherence in the long-term is a subject of speculation but requires further reinforcement through additional studies.
RESUMEN
BACKGROUND AND PURPOSE: Clinical status of subjects with knee osteoarthritis (KOA) is influenced by a complex interaction of several biopsychosocial factors. The use of patient-reported measures (PROM) is considered the gold standard for their evaluation. However, considering that 1 in 5 subjects with KOA present with depressive symptoms, it is necessary to analyse how this psychological domain may influence the subjective perception of PROM. The objective was to study the impact that depressive symptoms have on functional outcome assessments, according to the degree of objectivity of diverse outcome measures. METHODS: Cross-sectional study. Subjects with severe KOA, verified with clinical and radiological symptoms, were assessed with patient-reported (Oxford Knee Score), clinician-reported (knee range of motion), and performance-based (Timed up and go test) measures. The existence of depressive symptoms was assessed with the Yesavage scale, and participants were classified for having no-, mild- or severe-symptoms. Linear correlations (r) and one-way analysis of variance compared groups (95% CI). RESULTS: 244 participants were analysed, of which 75 (30.7%) had depressive symptoms. These symptoms had an inverse moderate association with Oxford Knee Score (r = -0.387). However, the correlation with the Timed up and go test was low (r = 0.176), while there was no correlation with knee ROM (r = -0.087). CONCLUSIONS: This study supports that patient-reported questionnaires may offer biased information on the clinical status of patients with severe knee osteoarthritis who present with depressive symptoms. Consideration of such symptoms may be critical to ensure data collected to accurately reflect patients' capacities and perceptions.

BACKGROUND: Rehabilitation is essential to optimize outcomes after surgical procedures in musculoskeletal disorders. However, adherence to rehabilitation continues to be an important barrier, since compliance with the programs is not always as desired, which may have a negative impact on clinical results. METHODS: Randomized controlled trial aimed at to determining the effectiveness of using a virtual assistant (i.e., chatbot) to promote adherence to home rehabilitation. Overall, seventy patients under 75, undergoing total knee replacement, who have a personal smartphone and are familiar with its use, will be assigned into the control (standard care) or the experimental (standard care plus virtual assistant) group. Adherence (primary outcome) will be assessed three months after surgery. The WOMAC questionnaire, knee pain and system usability scale will be also outcomes of interest at three months and one year. Overall, an analysis of variance will look for possible time, group and time*group interactions. DISCUSSION: The expected result is to determine whether the use of a chatbot that interacts with the patient can increase adherence to post-surgical home physiotherapy, and result in better clinical results (functional and pain) than standard care.

Background and Objectives: While suspension training devices are increasingly gaining popularity, there is limited evidence on their effects on balance, and no comprehensive assessment has been conducted. This study aimed to evaluate the effects of a 9-session suspension training program on dynamic and static balance, stability, and functional performance. Materials and Methods: A total of forty-eight healthy adults, aged between 18 and 30, participated in a 9-session suspension training program. The program included exercises targeting upper and lower body muscles as well as core muscles. Balance was comprehensively assessed using various dynamic balance tests, including the Y Balance Test (YBT) as the primary outcome, single-leg Emery test, and sideways jumping test. Static balance was evaluated through the monopedal and bipedal Romberg tests. Changes from baseline were analyzed using a one-way ANOVA test. Results: Thirty-nine participants (mean age: 21.8 years) completed the intervention. The intervention resulted in significant improvements in YBT, jumping sideways, Emery, and 30s-SST scores (p < 0.001). Platform measures indicated enhanced monopedal stability (p < 0.001) but did not show a significant effect on bipedal stability (p > 0.05). Conclusions: Suspension training is a safe and feasible method for improving dynamic balance and functional performance in healthy, untrained young adults. However, it does not appear to significantly impact the ability to maintain a static posture while standing.

To propose a fall-classification framework for patients undergoing total knee replacement (TKR). In addition, we reinforced the available evidence on fall incidence and circumstances and compared the characteristics of fallers versus. nonfallers. Retrospective and prospective data were collected from 253 subjects with severe knee osteoarthritis who were waiting for primary TKR. Falls were classified considering the location of the destabilizing force, source of destabilization and fall precipitating factor. Fall incidence and circumstances were described; the characteristics of fallers and nonfallers in terms of functional and balance performance were compared with F-tests (95% CI). The fall incidence before surgery was 40.3% (95% CI 34.2% to 46.6%). This figure decreased to 13.1% (95% CI 9.2% to 18.0%) and to 23.4% (95% CI 17.8% to 29.6%) at 6 and 12 months after surgery, respectively. Most falls were caused by destabilizations in the base of support (n = 102, 72%) and were due to extrinsic factors (n = 78, 76%) and trip patterns. Significant differences between fallers and nonfallers were found in knee extensor strength and monopodal stability in the surgical limb (p < 0.05). Falls are prevalent in patients with severe knee osteoarthritis. Symptoms and functional performance improve after surgery, and fall incidence is reduced. Most fall events originate from disruptions in the base of support and are precipitated by extrinsic factors, generally trips during walking activities.

BACKGROUND: The ankle plays a key role in balance, but ankle range of motion decreases with ageing. RESEARCH QUESTION: To establish whether a talus mobilization-based manual therapy intervention may be effective for increasing range of motion and balance in older adults with limited ankle mobility due to the ageing process. METHODS: Randomized clinical trial in which 42 community-dwelling older adults with limited ankle mobility were allocated to an experimental or a control group. The experimental intervention consisted of six sessions of anteroposterior talus mobilization, whereas the control intervention was a sham treatment. Baseline change in weight and non-weight bearing ankle range of motion (ROM), balance outcome in terms of the Timed up and go (mobility and dynamic balance), Single-leg stand (static balance and stability), Functional reach (margins of stability) and Romberg tests (static balance) were assessed. Analysis of variance based on a mixed-linear model of repeated measures looked for group interactions. RESULTS: Forty participants completed the study. Participants who received six sessions of manual therapy showed greater improvements in the Timed up and go, Functional reach and Single-leg stand tests than participants who received a sham intervention (p < 0.001). Both groups presented similar performance in post-treatment static balance measures (p > 0.05). SIGNIFICANCE: An anteroposterior talus mobilization-based manual therapy intervention is effective for increasing ankle ROM, with a positive effect on dynamic balance, mobility and stability in community-dwelling older adults with limited ankle mobility.

BACKGROUND AND PURPOSE: Ankle function declines with age. The objective of this study was to investigate the association between ankle function and balance in older adults, with a focus on range of motion (ROM) and strength. METHODS: This was a cross-sectional study that included 88 healthy community-dwelling older adults. Ankle mobility was measured while bearing weight (lunge test) and not bearing weight. The plantar-flexor muscle strength was assessed using a hand-held dynamometer. Balance was measured in terms of dynamic balance and mobility (timed up and go test), monopodal and bipodal static balance with open and closed eyes (single-leg stand test and platform measures), and margins of stability (functional reach test). Linear correlation and multiple regression analyses were conducted with a 95% CI. RESULTS AND DISCUSSION: Most participants had limited ankle mobility (n = 75, 86%). Weight-bearing ankle dorsiflexion ROM was the strongest predictor of dynamic balance and included general mobility and stability ([Formula: see text] = [0.34]; ß = [-0.50]). In contrast, plantar-flexor muscle strength was a significant predictor of static standing balance with open eyes ([Formula: see text] = [0.16-0.2]; ß = [0.29-0.34]). Overall, weight-bearing ankle dorsiflexion ROM was a more representative measure of balance and functional performance; however, a non-weight-bearing mobility assessment provides complementary information. Therefore, both measures can be used in clinical practice. CONCLUSION: This study supports the concept that ankle mobility contributes to the performance of dynamic tasks, while the plantar-flexor muscle strength helps to develop a standing static balance. Identification of alterations in ankle function is warranted and may assist in the design of tailored interventions. These interventions can be used in isolation or to augment conventional balance training in order to improve balance performance in community-dwelling older adults.

BACKGROUND: Altered muscle activation patterns and proprioception, loss of strength, and weight bearing asymmetries are common limitations after total knee arthroplasty, which can also affect balance. Therefore, preoperative sensorimotor training has been proposed to enhance surgical outcome. RESEARCH QUESTION: Is preoperative sensorimotor training effective in improving functional outcome in patients undergoing total knee arthroplasty? Does preoperative sensorimotor training affect secondary outcomes such as balance, pain, and quality of life? METHODS: A systematic review and meta-analysis were conducted by searching PEDro, MEDLINE, Embase, Cochrane Library, and Scopus databases from inception to May 2020. Studies were eligible if participants underwent total knee arthroplasty after two or more weeks of preoperative sensorimotor training. A meta-analysis compared the effects of such interventions with standard care before and after surgery using standardized mean differences (SMD) with 95 % confidence interval (CI). Functional outcome was the primary measure. Balance, pain, and quality of life were also outcomes of interest. RESULTS: Of the 384 items identified, 7 met the inclusion criteria, and 332 participants were assessed. There was limited evidence suggesting that preoperative sensorimotor training enhanced self-reported function (SMD, 0.89; 95 % CI, 0.16-1.62), functional performance (SMD, 0.56; 95 % CI, 0.19 to 0.93), or knee function (SMD = 0.22-1.05) compared with conventional care. Moderate quality evidence suggested that benefits were only maintained in terms of functional performance up to 3 months after surgery (SMD = 0.37; 95 % CI, 0.13 to 0.62). The outcome was similar after one year. SIGNIFICANCE: Compared with conventional care, preoperative sensorimotor training may enhance early postoperative functional recovery, with no additional benefits on balance, knee function, or pain. The outcome is the same one year after surgery, regardless of whether such training is implemented. Further investigation is needed to determine whether sensorimotor training may be a feasible conservative treatment for severe knee osteoarthritis.

Purpose. To assess the effects of training with virtual reality tools (VRT) during rehabilitation of patients after total knee replacement (TKR). Methods. Systematic review. Six databases were queried. Search criteria included studies in which participants underwent TKR, took part in a rehabilitation protocol with VRT, and clinical outcomes of rehabilitation were considered. Available demographic, interventional and outcome data, along with functional, balance, and pain outcome measures were extracted. Patient satisfaction was also summarized. Results. Six trials were included. Available information shows that multi-modal intervention with VRT is used primarily to augment conventional rehabilitation. The Wii Balance Board is the most frequently used device. Conclusions. Findings suggest that an augmented VRT physical therapy intervention that is specifically-oriented to enhance balance could be more effective for overcoming balance limitations than standard physical therapy. However, rehabilitation with VRT has no advantage over conventional training for enhancing function, resolving pain, or increasing patient satisfaction after TKR. Future studies are needed to confirm the findings, particularly regarding the feasibility of preoperative and continued in-home intervention. Registration: CRD42017057087.

PURPOSE: To investigate the effects of including balance training in a preoperative strengthening intervention on balance and functional outcomes in patients undergoing total knee replacement (TKR) and compare these effects to those induced by preoperative strengthening and no intervention. METHODS: Eighty-two subjects scheduled for TKR were randomly allocated into the strengthening (ST, n = 28) group: a preoperative lower limb strengthening intervention; the strengthening + balance (ST + B, n = 28) group: same intervention augmented with balance training; and the control group (n = 26). The Berg Balance Scale (BBS) and the function in daily living subscale of the Knee Injury and Osteoarthritis Outcome Score (KOOS-ADL) were the primary outcomes. The secondary measures included balance and mobility, self-reported status, and knee function. The outcomes were assessed at baseline, 1 week before surgery, and 2, (primary endpoint), 6 and 52 weeks after surgery. RESULTS: Compared with the controls, the participants in the ST and ST + B groups presented significant improvements from baseline to the end of the preoperative intervention in BBS (p = 0.005) and KOOS-ADL (p < 0.001). At 6 weeks post-surgery, the knee extensor strength values were similar in the two treatment groups and significantly higher than that in the controls. Overall, the participant outcomes in all groups stabilized at 1 year after surgery. CONCLUSION: A preoperative strengthening intervention, regardless of whether it is complemented with balance training, enhances strength but not balance or functional outcomes at 6 weeks after surgery. Patients are expected to present similar performance at 1 year postoperatively, but adequately statistically powered trials are needed to confirm the findings. LEVEL OF EVIDENCE: II. TRIAL REGISTRATION: NCT02995668.

BACKGROUND: Loss of knee extensor strength in individuals with knee osteoarthritis (KOA) may induce inter-limb strength asymmetries and alter functionality. The aims were to analyse whether the condition of the uninvolved knee (advanced to severe KOA or no affection) may induce different degrees of knee extensor strength asymmetry in individuals with KOA and to study whether functionality may differ in cases of unilateral or bilateral KOA. METHODS: Sixty-eight subjects with advance-to-severe KOA were categorized into two groups (unilateral or bilateral KOA). The knee extensor strength ratio (KESR), and self-reported and performance-based functionality were analysed and compared. Sex and age were independent factors. One- and two-way analysis of variance assessed for significant between-group differences (95% confidence interval (CI)). RESULTS: Participants with unilateral KOA presented with 20% knee extensor strength asymmetry. The mean difference with the bilateral KOA group in terms of Knee Extensors Strength Ratio was 0.2 (95% CI 0-0.3; P = 0.021), of the Oxford Knee Scale score was 4.2 (95% CI 3.4-5.1; P = 0.037), and of the Timed Up and Go was 1.3 s (95% CI 0.5-2.2; P > 0.05). There were significant sex and age interactions (P < 0.05). CONCLUSIONS: Individuals with unilateral or bilateral KOA present with different degrees of knee extensor strength asymmetry. The non-affected knee seems to help to better develop functional tasks in cases of unilateral condition. The findings may help the design of tailored strengthening interventions in which each knee condition in individuals with KOA should be considered.

OBJECTIVE: To determine the most frequently used outcome measures in total knee replacement rehabilitation trials. LITERATURE SURVEY: Systematic review of randomized trials searched in five databases: Web of Science, MEDical Literature Analysis and Retrieval System, Physiotherapy Evidence Database, Scopus, and Cochrane Library. METHODOLOGY: Trials were included if participants underwent total knee replacement rehabilitation and outcome measures were used to assess rehabilitation outcomes. A descriptive synthesis determined the frequency of using outcome measures and preferred assessment time points. Outcomes were classified into eight categories: patient- and clinician-reported function, performance-based function, balance, anxiety and depressive symptoms, quality of life, and others. SYNTHESIS: Eighty-one trials were included and 102 different outcome measures were classified. The most frequently reported outcome was knee range of motion, used in 54% of trials, followed by a visual analog scale of pain (43%) and Western Ontario and McMaster Universities Arthritis Index (WOMAC; 40%). Patient- and clinician-reported function were the categories most frequently assessed (74%), whereas performance-based measures were implemented by 56% of trials. The most frequent assessment time points were 1 week presurgery (52%) and 3 months postsurgery (39%). CONCLUSIONS: There is consensus regarding the need to evaluate functional outcomes in total knee replacement rehabilitation trials but none regarding the outcome measure that should be used. These findings suggest that most trials include patient- and clinician-reported functional measures, along with pain and performance-based measures in trial designs.

OBJECTIVE: To assess the effects of preoperative balance training on the early postoperative balance and functional outcomes after total knee replacement surgery and to test whether an outpatient intervention may be as effective as a domiciliary intervention. DESIGN: This is a three-arm randomized controlled trial. SETTING: University hospital. SUBJECTS: Eighty-six individuals were recruited. Seventy-seven were analysed, aged 72.1 (SD 7.6) years, of which 68% were women. OUTCOME MEASURES: Overall state of balance, as measured with the Berg Balance Scale, and patient-perceived functionality, as measured with the Knee Injury and Osteoarthritis Outcome Score Function in Activities in Daily Living (KOOS-ADL) questionnaire, were the primary outcomes. Secondary assessments targeted knee function, balance and mobility, quality of life, and self-reported outcomes. The primary end-point was six weeks after surgery. INTERVENTION: The hospital group implemented a four-week preoperative outpatient balance-oriented intervention. The home group implemented similar training, but this was domiciliary. The control group was instructed to keep performing their normal activities. RESULTS: Home and hospital groups presented a moderate effect against the control group (dhospital-control = 0.54; dhome-control = 0.63), both being similarly effective in improving the overall state of balance at six weeks after surgery (P = 0.013). KOOS-ADL scores showed no between-group differences and a small effect size (d < 0.5; P = 0.937). Secondary assessments suggested non-significant between-group differences. CONCLUSION: Preoperative balance training, conducted either as domiciliary or as an outpatient, is an effective approach to enhance early postoperative balance outcome but not the perceived functionality of individuals undergoing total knee replacement.

BACKGOUND: Balance and proprioceptive deficits are frequently persistent after total joint replacement, limiting functionality and involving altered movement patterns and difficulties in walking and maintaining postural control among patients. RESEARCH QUESTION: The goal of this systematic review was to evaluate the short- and mid-term effects of proprioceptive and balance training for patients undergoing total knee and hip replacement. METHODS: This is a systematic review of literature. MEDLINE, Embase, Cochrane Library, PEDro, and Scopus were the databases searched. The review included randomized clinical trials in which the experimental groups underwent a training aimed at improving balance and proprioception, in addition to conventional care. The studies had to assess at least one of the following outcomes: self-reported functionality or balance (primary outcomes), knee function, pain, falls, or quality of life. RESULTS: Eight trials were included, involving 567 participants. The quantitative synthesis found a moderate to high significant effect of balance and proprioceptive trainings on self-reported functionality and balance after total knee replacement. The effects were maintained at mid-term in terms of balance alone. Conversely, preoperative training did not enhance outcomes after total hip arthroplasty. SIGNIFICANCE: The synthesis showed that, in clinical terms, balance trainings are a convenient complement to conventional physiotherapy care to produce an impact on balance and functionality after knee replacement. If outcomes such as improvement in pain, knee range of movement, or patient quality of life are to be promoted, it would be advisable to explore alternative proposals specifically targeting these goals. Further research is needed to confirm or discard the current evidence ultimately, predominantly in terms of the effects on the hips and those yielded by preoperative interventions.

BACKGROUND AND PURPOSE: Sensorimotor training has proven to be an efficient approach for recovering balance control following total knee replacement (TKR). The purpose of this trial was to evaluate the influence of specific balance-targeted training using a dynamometric platform on the overall state of balance in older adults undergoing TKR. METHODS: This was a randomized controlled clinical trial conducted at a university hospital rehabilitation unit. Patients meeting the inclusion criteria were randomly assigned to a control group or an experimental group. Both groups participated in the same 4-week postoperative rehabilitation training protocol. Participants in the experimental group performed additional balance training with a dynamometric platform consisting of tests related to stability challenges, weight-shifting, and moving to the limits of stability. The primary outcome measure was the overall state of balance rated according to the Berg Balance Scale. Secondary outcomes in terms of balance were the Timed Up and Go Test, Functional Reach Test, and Romberg open and closed-eyes tests. Data processing included between-group analysis of covariance, minimal detectable change assessment for the primary outcome measure, and effect size estimation. Confidence intervals (CIs) were set at 95%. RESULTS: Forty-three participants meeting the inclusion criteria and having signed the informed consent were randomly assigned to 2 groups. Thirty-seven completed the training (86.1%). Significant between-group differences in balance performance were found as measured with the Berg Balance Scale (P = .03) and Functional Reach Test (P = .04) with a CI = 95%. Significant differences were not recorded for the Timed Up and Go Test or Romberg open and closed-eyes tests (P > .05). Furthermore, Cohen's effect size resulted in a value of d = 0.97, suggesting a high practical significance of the trial. DISCUSSION AND CONCLUSIONS: According to the Berg Balance Scale and Functional Reach Test, participants with TKR who have followed a 4-week training program using a dynamometric platform improved balance performance to a higher extent than a control group training without such a device. The inclusion of this instrument in the functional training protocol may be beneficial for recovering balance following TKR.

BACKGROUND: Severe knee osteoarthritis, as well as the surgical procedure of total knee replacement that aims to reduce its symptoms, cause great deterioration on the proprioceptive system. Taking this fact into account, and considering that balance abilities positively influence the capacity to perform basic functional tasks, this trial aims to find the short and mid-term effects of a preoperative balance and proprioceptive training when conducted by patients undergoing total knee replacement. Along with the effects, it is intended to determine whether in-home based training can be as effective as hospital training. The results will help to conclude whether the possible benefits may outweigh the health costs. METHODS: Seventy-five participants will take part. The trial will include in-home and supervised hospital experimental training compared to a non-active control group in order to estimate the actual effect of the proposal against the benefits due exclusively to the surgical procedure. Interventions last 4 weeks prior to surgery, and the follow-up will be at 2w, 6w, and 1y following the operation. The primary outcomes are in agreement with the goals: self-reported functionality in terms of KOOS and overall balance in terms of the Berg Balance Scale. The secondary outcomes will include the measurements of static and dynamic balance abilities, pain, function, and quality of life. DISCUSSION: It is expected for the results of this trial to provide relevant information in order to decide if a specific intervention is cost-effective to be implemented in clinical practice.
