Trunk motion visual feedback during walking improves dynamic balance in older adults: Assessor blinded randomized controlled trial.

ABSTRACT: BACKGROUND:Virtual reality and augmented feedback have become more prevalent as training methods to improve balance. Few reports exist on the benefits of providing trunk motion visual feedback (VFB) during treadmill walking, and most of those reports only describe within session changes. RESEARCH QUESTION:To determine whether trunk motion VFB treadmill walking would improve over-ground balance for older adults with self-reported balance problems. METHODS:40 adults (75.8 years (SD 6.5)) with self-reported balance difficulties or a history of falling were randomized to a control or experimental group. Everyone walked on a treadmill at a comfortable speed 3×/week for 4 weeks in 2?min bouts separated by a seated rest. The control group was instructed to look at a stationary bulls-eye target while the experimental group also saw a moving cursor superimposed on the stationary bulls-eye that represented VFB of their walking trunk motion. The experimental group was instructed to keep the cursor in the center of the bulls-eye. Somatosensory (monofilaments and joint position testing) and vestibular function (canal specific clinical head impulses) was evaluated prior to intervention. Balance and mobility were tested before and after the intervention using Berg Balance Test, BESTest, mini-BESTest, and Six Minute Walk. RESULTS:There were no significant differences between groups before the intervention. The experimental group significantly improved on the BESTest (p?=?0.031) and the mini-BEST (p?=?0.019). The control group did not improve significantly on any measure. Individuals with more profound sensory impairments had a larger improvement on dynamic balance subtests of the BESTest. SIGNIFICANCE:Older adults with self-reported balance problems improve their dynamic balance after training using trunk motion VFB treadmill walking. Individuals with worse sensory function may benefit more from trunk motion VFB during walking than individuals with intact sensory function.

Project description:Objective: To evaluate the immediate and long-term effects of 12 weeks of Tai Chi training on dynamic balance and disease severity among individuals with cerebellar ataxia (CA). Design: An assessor-blinded, two-arm, parallel-group randomized-controlled trial was conducted among 24 participants with CA. Participants were randomized to receive either Tai Chi intervention (n = 12) or usual care (n = 12). Dynamic balance was assessed using the Berg Balance Scale (BBS), Scale for the Assessment and Rating of Ataxia (SARA) balance sub-component of the SARA (SARAbal), Sensory Organization Test, and Limits of Stability test. Disease severity was assessed using the SARA and health-related quality of life using the EuroQol visual analog scale. Assessments were completed at baseline (week 0: T1), postintervention (week 12: T2), and at the end of the 24-week (week 36: T3) follow-up period. Interventions: The 8-form Tai Chi exercise was delivered in 60-min sessions, three times a week for 12 weeks. Participants were asked to complete an unsupervised home Tai Chi exercise program over the next 24 weeks. Participants in the usual care control group completed all study measures but did not receive any intervention. Results: Compared with the usual care control group, after 12 weeks of Tai Chi training, the experimental group demonstrated beneficial effects for dynamic balance assessed using the BBS (mean difference [MD]: 4, 95% confidence interval [CI]: -1.06 to 8.71) and the SARAbal (MD: -1.33, 95% CI: -2.66 to 2.33). The effect size ranged from small to large. The benefits gained were not sustained after 24 weeks during the follow-up assessment. Tai Chi did not benefit disease severity and health-related quality of life in this population. Conclusion: Some evidence supports the immediate beneficial effects of 12 weeks of Tai Chi training on the dynamic balance among individuals with CA.

Project description:BACKGROUND:Impaired reactive balance control can lead to increased falls in people with neurological impairments. Perturbation-based balance training (PBT), which involves repetitive exposure to destabilizing external perturbations, improves the ability to take reactive steps in older adults and individuals who have had a stroke. OBJECTIVE:The objective is to investigate whether PBT or conventional intensive balance training (CIBT) results in greater improvements in reactive stepping ability in individuals with chronic incomplete spinal cord injury (iSCI). DESIGN:The design consists of an assessor-blind randomized clinical trial comparing the efficacy of 2 balance training programs (PBT and CIBT) matched for training duration (thrice weekly for 8 weeks). SETTING:A tertiary spinal cord injury rehabilitation center is used as the setting. PARTICIPANTS:Participants include 24 adults with iSCI classified as a C or D on the American Spinal Association Impairment Scale, who are able to stand independently and exhibit moderate trunk control. INTERVENTION:Both PBT and CIBT involve 24 sessions, each 1 hour long, of individualized static and dynamic balance tasks. However, PBT includes external, unexpected balance perturbations provided manually by the trainer at a frequency of roughly 1 per training minute. MEASUREMENTS:The primary outcome is the ability to recover balance using a single step during the Lean-and-Release test, a novel method of assessing reactive balance. Secondary outcomes include a number of clinical balance and gait assessments, and the number of falls experienced in a 6-month follow-up period. Semi-structured interviews are conducted 3 months after training completion to gain insight into the participants' perceptions of the impact of the interventions. LIMITATIONS:A control group receiving "standard care" for balance training is not included. CONCLUSIONS:This trial will provide physical therapists with insight into the efficacy of 2 forms of balance training for individuals with iSCI.
