Effect of Biofeedback Activation on Balance in Osteoporotic Elderly

Effect of Biofeedback Activation on Balance in Osteoporotic Elderly Patients

This study aimed to investigate the effect of gluteus medius activation using electromyography (EMG) biofeedback combined with balance training on balance, physical performance, gluteus medius muscle activity, and quality of life in osteoporotic elderly patients.

Description

Inclusion Criteria:

• All patients included in this study met the following criteria:

  1. Sixty patients of both sexes were diagnosed with osteoporosis confirmed by bone density test through Dual-energy X-ray absorptiometry (DEXA) scan (A T-score equal to or less than - 2.5) (Sheu and Diamond, 2016).
  2. Their age ranged between 65 - 75 years.
  3. Their BMI ranged between 25 - 29.9 kg/m2.
  4. They had good mentality and cognitive function.

Exclusion Criteria:

• The potential patients were excluded if they have one of the following criteria:

  1. Patients with endocrine disorders likely to be related to metabolic bone disease, such as premature ovarian failure, hypogonadism, untreated hyperthyroidism, hyperparathyroidism, adrenal insufficiency or Cushing's syndrome.
  2. Patients with active contagious skin conditions.
  3. Patients with implant devices such as pacemaker or electrical prosthesis.
  4. Any cardiopulmonary disorders.
  5. Any neuromuscular disorders.
  6. Any acute viral infection.
  7. Patients with ascites or end stage liver or kidney failure.
  8. Leg discrepancy.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Gluteus medius isometric strengthening using EMG with traditional balance training; received 30 minutes of traditional balance training (functional strength, static and dynamic balance, and gait training) followed by 30 minutes of gluteus medius isometric strengthening using EMG biofeedback, three times per week, for four consecutive weeks.	Device: Electromyographic (EMG) biofeedback; a physical therapy intervention that uses auditory and visual feedback to control the contraction or relaxation of muscles. Repeated biofeedback training can induce motor learning of muscles. Biofeedback enhances the function of pelvic floor muscles by enhancing the force generation, correct timing, and coordination of the pelvic floor muscles. Electromyography Biofeedback is considered as a behavioural therapy training modality
Active Comparator: Traditional balance training only; received balance training alone with the same frequency and duration.	Other: Balance training; functional strength, static and dynamic balance, and gait training
