  Purpose
Falling is a complex and most disabling feature for patients with Parkinson's disease (PD). Previous studies suggested that falls in patients with PD are related to postural instability characterized by deficits in anticipatory postural adjustment (APA) for postural orientation in walking and standing and inadequate postural response to perturbation. The present study developed an innovative balance treatment with focus of anticipatory and compensatory postural control and examined its effects on enhancing balance and gait performance and decreasing fall rate in people with PD.

Primary Outcome Measures:
  • reaction time of limits of stability test [ Time Frame: One year ]
  • one-leg-stance time [ Time Frame: one year ]
  • pull test [ Time Frame: one year ]
    it reflects the ability of compensatory postural control in patients with Parkinson's disease

  • fall rate [ Time Frame: previous one year before baseline assessment, each following one month for 3-month of training and 12-month of follow-up ]
  • movement velocity of limit of stability test [ Time Frame: one year ]
  • end point excursion of limits of stability test [ Time Frame: One year ]

Secondary Outcome Measures:
  • Unified Parkinson`s Disease rating scale- motor examination subscale [ Time Frame: one year ]
    it reflects motor impairment of patients with Parkinson's disease

  • Gait velocity [ Time Frame: one year ]
  • Stride length [ Time Frame: One year ]
  • Cadence [ Time Frame: One year ]

Arms Assigned Interventions
Experimental: anticipatory and compensatory postural control training
Subjects in the experimental group were trained the speed and amplitude of anticipatory postural adjustment during fall-prone activities and postural response to perturbation during walking. Training was provided with preparatory cues, computerized machines and treadmill.
Other: experimental
Subjects in the experimental group were trained the speed and amplitude of anticipatory postural adjustment during fall-prone activities and postural response to perturbation during walking. Training was provided with preparatory cues, computerized machines and treadmill.
Active Comparator: strength-focused training
Subjects in control group were provided with strength training of leg muscles using machines and during functional activities.
Other: control
Subjects in control group were provided with strength training of leg muscles using machines and during functional activities.

Detailed Description:

Participants: Forty-two eligible subjects with PD were randomly allocated into balance with focus of anticipatory and compensatory postural control (EXP) or control (CON) group with strength-focused training, with 26 subjects in each group.

Methods: Subjects in the EXP group were trained the speed and amplitude of anticipatory postural adjustment during stepping and walking and postural response to perturbation during walking. Subjects In the CON group were trained to improve the strength of lower limb muscles. Treatment period in both groups lasted for 12 weeks, which consisted of 4-week laboratory-based training (phase 1), 4-week home-based exercise (phase 2) and final 4-week laboratory-based training (phase 3). Outcome measures included reaction time(RT), movement velocity (MV) and endpoint excursion (EPE) of limit-of-stability test, one-leg-stance (OLS) time, gait velocity, stride length (SL), cadence, and fall rate. All tests were conducted for 6 time intervals including baseline, after each training phase, at 3-month follow-up and at 12-month follow-up.
