Results and Conclusions Although most available studies did not systematic ally evaluate feasibility aspects , reports of high participation rates , low drop-out rates , absence of adverse events and positive training experiences suggest that biofeedback methods can be applied in older adults .
An indication for effectiveness of visual feedback-based training of balance in ( frail ) older adults was identified for postural sway , weight-shifting and reaction time in st and ing , and for the Berg Balance Scale .
Indications for added effectiveness of applying biofeedback during training of balance , gait , or sit-to-st and transfers in older patients post-stroke were identified for training-specific aspects .
The same applies for auditory feedback-based training of gait in older patients with lower-limb surgery .
Implication sFurther appropriate studies are needed in different population s of older adults to be able to make definitive statements regarding the ( long-term ) added effectiveness , particularly on measures of functioning
Context An effective application of biofeedback for interventions in older adults with balance and mobility disorders may be compromised due to co-morbidity .
Objective To evaluate the feasibility and the effectiveness of biofeedback-based training of balance and /or mobility in older adults .
Electromyographic biofeedback for gait training after stroke
Objective : To examine the effects of electromyographic ( EMG ) biofeedback training on the recovery of gait in the acute phase post stroke . Design : Patients were r and omly assigned to EMG biofeedback or control groups . They received treatment three times a week for six weeks . All patients were assessed prior to treatment , after 18 treatment sessions , and at three months follow-up . Setting : The study was carried out at Scunthorpe General Hospital in North Lincolnshire . The subjects were acute stroke patients who had been admitted on to the medical and elderly wards . Interventions : The EMG biofeedback group were treated using EMG as an adjunct to physiotherapy . The patients were encouraged to facilitate or inhibit abnormal muscle tone via auditory or visual signals transmitted from electrodes placed over the appropriate muscles . The control group were treated using the same techniques , electrodes were used with this group of patients , but the EMG machine was turned off and faced away from the patient and the therapist to control the placebo effect . Outcome measures : A large battery of outcome measures was used for physical and psychological assessment . The physical measures consisted of active movement , muscle tone , sensation , proprioception , mobility and activities of daily living ( ADL ) . The psychological measures included orientation , memory , spatial performance , language and IQ . Results : Twenty-one patients were included in the study . Scores were combined into four groups : mild EMG , severe EMG , mild control and severe control . Results showed that there was an improvement in physical scores for active movement , mobility and ADL over time , but there was no significant difference between the EMG and control groups . Scores on the psychological tests were within normal limits , and there was no difference in performance between the EMG and control groups . Conclusions : This study showed no significant differences in the rate of improvement after stroke between the two groups . Although EMG biofeed-back was used as an adjunct to physiotherapy and represented clinical practice , the results provide little evidence to support the clinical significance of using EMG biofeedback to improve gait in the acute phase after stroke
