Regular Follow-Up Increases Ground Reaction Forces During a Home-Based Exercise Intervention to Improve Bone Mass in Young Women

Background:Clinical practice guidelines recommend that exercise is an essential component in the self-management of Ankylosing Spondylitis (AS). Attending supervised interventions requiring periodic medical center visits can be burdensome and patients may decline participation, whereas, effective home-based exercise interventions that do not need regular medical center visits are likely to be more accessible and acceptable for patients with AS. Recently, increasing evidences have been accumulated that the wearable devices could facilitate patients with inflammatory arthritis by giving exercise instructions and improving self-efficacy. Therefore, patients with AS may benefit from an effective technology-assisted home-based exercise intervention.Objectives:To investigate the efficacy of a comprehensive technology-assisted home-based exercise intervention on disease activity in patients with AS.Methods:This study was a 16-week assessor-blinded, randomized, waiting-list controlled trial (ChiCTR1900024244). Patients with AS were randomly allocated to the home-based exercise intervention group and the waiting-list control group. A 16-week comprehensive exercise program consisting of a moderate intensity (64%-76% HRmax) aerobic training for 30min on 5 days/week and a functional training for 60min on 3 days/week was given to patients in the intervention group immediately after randomization, with 1.5h training sessions for two consecutive days by a study physical therapist at baseline and Week 8. The aerobic exercise intensity was controlled by a Mio FUSE Wristband with a smartphone application. The functional training consisted of the posture training, range of motion exercises, strength training, stability training and stretching exercises. Patients in control group received standard care during the 16-week follow-up and started to receive the exercise program at Week 16. The primary outcome was ASDAS at Week 16. The secondary outcomes were BASDAI, BASFI, BASMI, ASAS HI, peak oxygen uptake, body composition and muscle endurance tests. The mean difference between groups in change from baseline was analyzed with the analysis of covariance.Results:A total of 54 patients with AS were enrolled (26 in intervention group and 28 in control group) and 46 (85.2%) patients completed the 16-week follow-up. The mean difference of ASDAS between groups in change from baseline to 16-week follow-up was −0.2 (95% CI, −0.4 to 0.003, P = 0.032), and the mean change from baseline was -0.4 (95% CI, -0.5 to -0.2) in the intervention group vs -0.1 (95% CI, -0.3 to 0.01) in the control group, respectively. Significant between-group differences were found between groups for BASDAI (−0.5 [95% CI, −0.9 to −0.2], P = 0.004), BASMI (−0.7 [95% CI, −1.1 to −0.4], P <0.001), BASFI (−0.3 [95% CI, −0.6 to 0.01], P=0.035), peak oxygen uptake (2.7 [95% CI, 0.02 to 5.3] ml/kg/min, P=0.048) and extensor endurance test (17.8 [95% CI, 0.5 to 35.2]s, P=0.044) at Week 16. Between-group differences were detected in ASAS HI (−0.9 [95% CI, −1.7 to −0.1], P=0.030), body fat percentage (−1.0 [95% CI, −2.0 to −0.01] %, P=0.048) and visceral adipose tissue (−4.9 [95% CI, −8.5 to −1.4] cm2, P=0.008) at Week 8, but not at Week 16. No significant between-group differences were detected in the total lean mass, time up and go test and the flexor endurance test during the follow-up.Conclusion:Comprehensive technology-assisted home-based exercise has been shown to have beneficial effects on disease activity, physical function, spinal mobility, aerobic capacity, and body composition as well as in improving fatigue and morning stiffness of patients with AS.References:[1]van der Heijde D, Ramiro S, Landewé R, et al.

Summary Objective: To assess functional outcome in dogs with cranial cruciate ligament (CrCL) disease after tibial tuberosity advancement (TTA) using force plate gait analysis, and to evaluate parameters potentially influencing outcome. Study design: Prospective clinical study. Animals: Consecutive clinical patients (n=37) with CrCL-deficient stifles (n=40). Methods: The stifle joints were examined arthroscopically prior to TTA. Meniscal release was not performed if the medial meniscus was intact. Open medial arthrotomy and partial meniscectomy were performed in the presence of meniscal tears. Vertical ground reaction forces were measured preoperatively and at follow-up examinations four to 16 months postoperatively (mean: 5.9 months). The ground reaction forces of a group of 65 healthy dogs were used for the comparison. The potential effects of clinical parameters on functional outcome were evaluated statistically. Results: Complete CrCL rupture was identified in 28 joints, and partial CrCL rupture in 12 joints. The medial meniscus was damaged in 21 stifles. Vertical ground reaction forces were significantly higher at follow-up (P<0.01), but remained significantly lower than those of control dogs (P<0.01). Complications were identified in 25% of joints, and the dogs with complications had significantly lower peak vertical forces at follow-up than the dogs without complications (P=0.04). Other clinical parameters did not influence outcome. Conclusions: Tibial tuberosity advancement significantly improved limb function in dogs with CrCL disease, but did not result in complete return to function. Complications adversely affected functional outcome. Clinical significance: A return to a function of approximately 90% of normal can be expected in dogs with CrCL disease undergoing TTA.

Background:It remains unclear whether self-regulated exercise is sufficient to maintain the benefits acquired during formal cardiac rehabilitation (CR). This retrospective observational study investigated the effects of a home-based exercise intervention after discharge from CR upon anthropometric and aerobic capacity markers in clinically stable patients.Methods:Fifty patients with cardiovascular disease were discharged after 6 months of CR and encouraged to maintain aerobic exercise without supervision. Subsequent to 6 months of follow-up, patients were assigned to compliant (n = 34) or noncompliant (n = 16) groups according to their compliance to the home-based program. Maximal aerobic capacity (VO2peak) and anthropometric data were assessed before CR, at discharge, and after 6 months of follow-up.Results:No statistical differences between compliant and noncompliant groups were observed at baseline and at discharge from CR. At the end of the follow-up, statistical differences across groups were not found for body mass or body mass index, but increases in VO2peak (+3.6 vs. –0.6 ml/kg·min, P = 0.004) and oxygen pulse (+1.5 vs. +0.2 ml/bpm, P = .03) were greater in compliant than noncompliant group.Conclusions:Self-regulated exercising following CR discharge seems to be effective to maintain gains in exercise capacity acquired during supervised center-based programs.

Background:Previous research supports the efficacy of a 6-month DVD-delivered program for enhancing physical activity (PA) in older adults. In the current study, we examined the degree to which intervention-related increases in PA were maintained after a 6-month, no-contact follow-up.Methods:Follow-up assessments of PA via accelerometry and the Godin Leisure-Time Exercise Questionnaire (GLTEQ) were collected in a sample of older adults (N = 238). Repeated measures analyses of variance were conducted to examine changes in PA over the course of the follow-up period.Results:For accelerometer measured PA, there was a significant time × treatment × age group interaction, F1,203 =11.319, P = .001, η2 = .053, such that younger (≤70 years) intervention participants maintained high levels of PA across the follow-up period, while PA in older intervention and young control participants declined significantly. Rates of PA in older control participants remained low over the course of the follow-up period. Analyses of GLTEQ scores revealed similar, though less significant patterns.Conclusions:DVD-based exercise programs may be effective for maintaining PA in younger members of the older adult population; however, there remains a need to develop better strategies for promoting PA maintenance in older individuals when using home-based designs.

Predictors Of Adherence

Background:The purpose of this study was to (a) examine demographic, psychosocial, and physiological predictors of exercise adherence in a yearlong exercise intervention and (b) describe the trajectory of adherence over time.Methods:Participants were 51 men and 49 women aged 40 to 75 years. The supervised and home-based intervention consisted of 60 minutes/day, 6 days/week of moderate-to-vigorous intensity exercise. Three adherence measures were used: (1) minutes/week, (2) MET-hours/week, and (3) change in cardiopulmonary fitness (VO2max). Predictors of adherence were determined separately by sex using mixed models and multivariable regression.Results:Participants performed 287 ± 98 minutes/week of moderate-to-vigorous activity with 71% adhering to at least 80% (288 minutes/week) of the prescription. Men adhered better than women (P < .001). Among women, adiposity-related variables were significantly related to poorer adherence on all 3 measures (P < .05). A less consistent pattern was observed among men but in follow-up analyses, adiposity was associated with fewer MET-hours/week of exercise. Social support, pain, and perceived benefits were predictive in some models. Men and nonobese women experienced peak adherence at 4 to 6 months, while obese women peaked during months 0 to 3.Conclusions:When provided with supervision and support, previously sedentary men and women can achieve and maintain high levels of aerobic activity.

Background: Low back pain (LBP) is a prevalent condition affecting a large portion of the population world-wide and it is one of the leading causes of morbidity and work absenteeism. Objective: To investigate the effectiveness of a four-week, home-based exercise program in treating subacute LBP in adults. Methods: A quantitative, experimental research design was employed. Twenty male and female adults aged between 18 and 65 years with subacute LBP were recruited by means of advertisements and word of mouth and allocated into either a control group (CG) or a home-based exercise group (HG). Both groups underwent a pre-test that consisted of answering two questionnaires, the Visual Analogue Scale for Pain (VASP) and the Oswestry LBP and Disability Questionnaire. The (CG) received no intervention over the four-week intervention period, while the intervention group (HG) was given an exercise program and instructed to perform the exercises at home, three times a week for four weeks. After four weeks (post-test), the two questionnaires were repeated. After eight weeks (follow-up test) both groups again completed the two questionnaires. Descriptive statistics, non-parametric inferential statistics and Cohen’s effect size (d) were used to analyse the data and statistical significance was set at a confidence level of 95% (p?0.05). Results: Following the home-based exercise intervention there were significant improvements observed in lower back pain and function for the HG. The HG’s Oswestry scores improved significantly (p=0.005) and their VASP also showed a significant improvement (p=0.011). Significant improvements also occurred between the pre-test and four-week follow-up for the HG’s Oswestry score (p=0.021) and for the HG’s VASP (p=0.005). No significant improvement was found for the CG between pre-test and post-test or between pre-test and the four-week follow-up. Large effect sizes (d>0.8) were also observed for the HG between the pre- and the post-test (d=1.59) as well as between the HG and the CG at post-test (d=1.52) and at the four-week follow-up (d=1.6). Conclusion: The exercise intervention resulted in statistically significant and clinically significant improvements in both function and pain in adults with subacute LBP.

Bone Response

IntroductionThe aim of the Osteoporosis Prevention Through Impact and Muscle-loading Approaches to Exercise trial is to compare the bone response to two known osteogenic stimuli — impact loading exercise and resistance training. Specifically, we will examine the effect of a 10-month, twice-weekly, high-intensity impact loading exercise intervention and a 10-month, twice-weekly, high-intensity resistance training intervention on bone mass and strength at clinically important skeletal sites. The intervention groups will be compared against a home-based ‘positive’ control group. Safety and acceptability of each exercise modality will also be determined.Methods and analysisSedentary otherwise healthy young women aged 18–30 years with bone mineral density (BMD) T-scores less than or equal to 0 at the hip and lumbar spine, screened for conditions and medications that influence bone and physical function, will be recruited. Eligible participants are randomised to 10-month, twice-weekly, either supervised high-intensity impact training, high-intensity resistance training or a home-based ‘positive’ control group. The primary outcome measure will be lumbar spine areal BMD, while secondary outcome measures will include: whole body, femoral neck and regional measures (upper and lower limb) of bone, muscle and fat; anthropometrics; muscle strength and power; quality of life and exercise safety, enjoyment and acceptability. All outcome measures will be conducted at baseline (T0) and 10 months (T10) and will be analysed according to the intention-to-treat principle and per protocol.Ethics and disseminationThe study has been granted ethical approval from the Griffith University Human Research Ethics Committee (GU Ref: 2015/775). Standard scientific reporting practices will occur, including publication in peer-reviewed journals. Participant confidentiality will be maintained in all forms of reporting.Trial registration numberACTRN12616001444471.

Summary Objectives: In this report two cases of partial gastrocnemius muscle avulsion treated with pulsed therapeutic ultrasound are described. Methods: The outcome in these two dogs was evaluated using ultrasonographic imaging and the measurement of ground reaction forces with a force plate. Results: Both dogs showed an amelioration of the clinical signs within one month after commencement of the ultrasound therapy. The follow-up time for these cases was one year and six months respectively. Both of the dogs were free of lameness and had returned to their normal amount of exercise. Palpation of the fabella associated with the muscle injury did not produce any signs of pain. Ultrasonographic imaging did not detect any signs of haemorrhage or oedema, although scarring of muscle fibres was present. The force-plate analyses revealed an improvement. Clinical significance: These results suggest that therapeutic ultrasound could be a beneficial treatment modality for this kind of muscle injury.
