Brief Summary
Gait disorders represent disabling symptoms in Parkinson's Disease (PD). The effectiveness of rehabilitation treatment with Body Weight Support Treadmill Training (BWSTT) has been demonstrated in patients with stroke and spinal cord injuries, but limited data is available in PD. The aim of the study is to investigate the efficacy of BWSTT in the rehabilitation of gait in PD patients. Thirty-six PD inpatients were enrolled and performed rehabilitation treatment for 4 weeks, with daily sessions. Subjects were randomly divided into two groups: both groups underwent daily 40-minute sessions of traditional physiokinesitherapy followed by 20-minute sessions of overground gait training (Control group) or BWSTT (BWSTT group). The efficacy of BWSTT was evaluated with clinical scales and Computerized Gait Analysis (CGA). Patients were tested at baseline (T0) and at the end of the 4-week rehabilitation period (T1).
Detailed Description
Gait disorders in Parkinson Disease (PD) are due to dopaminergic nigrostriatal pathways degeneration and represent important components of the disability.
In PD, gait is characterized by a significant reduction of stride length. Inadequate flexion at the ankle and knee, reduction of heel strike, forward-flexed trunk, reduced arm swing with asymmetric stride times for lower limbs and significant stride-to-stride variability are frequently associated.
The efficacy of pharmacological treatment with Levodopa is frequently incomplete and adjuvant rehabilitation treatment is recommended. Body weight-supported treadmill training (BWSTT) represents a promising rehabilitative approach for gait impairment in PD. Effectiveness of BWSTT on gait, balance and motor function has been demonstrated in different neurological diseases, especially in stroke and spinal cord injury. In PD patients, BWSTT has been tested in small controlled studies that have suggested a clinically detectable beneficial effect. BWSTT seems also effective in improving balance in PD. In PD, many data in literature show how treadmill training, acting as a sensory cue, improves kinetic and kinematic parameters, studied with computerized gait analysis (CGA) more than physiotherapy alone.
The first report of BWSTT efficacy in gait rehabilitation of PD belongs to Miyai. Ten patients with PD were enrolled in a cross-over study and treated for 4 consecutive weeks with BWSTT (20% of unweighting for 12 minutes followed by another 12-min period of 10% of unweighting) or conventional physical therapy (CPT). The Authors showed that BWSTT was superior to CPT in improving gait disturbances and disability at the end of the rehabilitative period. More specifically BWSTT proved superior to CPT in improving UPDRS scores, gait speed and stride length. The same study group in 2002 evaluated the 6-month retention of BWSTT in PD. Twenty-four patients with PD were randomized to receive BWSTT (20% of unweighting for 10 minutes + 10% of unweighting for 10 minutes + 0% of unweighting for an additional 10-min period) or CPT 3 times/week for 4 consecutive weeks. All patients were clinically evaluated at baseline and them monthly for 6 months. In this series, gait speed significantly improved in BWSTT respect to CPT only at month 1, while the improvement in the stride length was more marked in BWSTT group with respect to CPT and persisted until month 4.
In 2008 Fisher speculated on the possible central mechanism responsible for clinical effects f BWSTT. Thirty subjects affected by PD were randomly assigned to three groups: high-intensity group (24 sessions of BWSTT), low-intensity group (24 sessions of CPT), zero-intensity group (8 weeks of education classes). Again, the high-intensity group improved the most at the end of treatment period, in particular in gait speed, step length, stride length and double support. Of note, that in this study a subgroup of patients was also tested with transcranial magnetic stimulation: in the BWSTT group Authors were able to record a lengthening of the cortical silent period, postulating that high-intensity training improved neuronal plasticity in PD, through BDNF and GABA modulation.
Ustinova published the first positive case report on the short-term gait rehabilitation efficacy of BWSTT delivered to a PD patient with a robotic device (Lokomat - Hocoma Inc., Volketswil, Switzerland). The intervention consisted in a 2-week gait training, delivered 3 times per week, with each session lasting 90 to 120 minutes.
Lo conducted a pilot study to assess the efficacy of BWSTT delivered with the Lokomat unit in reducing frequency of freezing (FOG) of gait in PD. Authors reported a 20% reduction in the average number of daily episodes of FOG and a 14% improvement in the FOG-questionnaire score.
In 2012 Picelli enrolled 41 PD patients in the first randomised controlled study aimed to compare the efficacy of BWSTT delivered with a robot-assisted gait training (RAGT - gait Trainer GT1) to CPT (not focused on gait training) in improving gait in PD. They showed how RAGT was significantly superior respect to CPT in improving the 6-minute walking test, the 10-meter walking test, stride length, single/double support ratio, Parkinson's Fatigue Scale and UPDRS score.
In the present study subjects were enrolled among consecutive PD patients hospitalized in the Neuro-Rehabilitation Unit of the IRCCS Mondino Foundation of Pavia, Italy. Thirty-six patients affected by Idiopathic PD, according to the UK Brain Bank diagnostic criteria were included. Subjects were randomly assigned to two groups: 18 PD patients were assigned to the "BWSTT group" and 18 patients to the "Control group". Before starting treatment, patients of BWSTT group performed a 20-minute single session of BWSTT in order to test feasibility and tolerability. Four of them did not tolerate BWSTT: one patient reported an increase in his pre-existing hip pain, two patients with pre-existing spondyloarthrosis complained of low back pain, one patient reported that the procedure induced anxious symptoms. These 4 patients were re-allocated to the control group, so that the final disposition of patients in the two groups was as follows: 14 patients (8 women and 6 men) in the BWSTT group and 22 patients (10 women and 12 men) in the Control group.
Patients in both groups underwent 5 daily rehabilitation sessions per week for 4 consecutive weeks. Both groups underwent daily 40-minute sessions of traditional physical therapy (PT) followed by a 20-minute session of overground gait training (Control group) or of gait training with BWSTT (BWSTT group).
The traditional PT rehabilitation treatment included passive, active and active-assisted exercises, according to the methods commonly used (Kabat, Bobath) and previously published (25, 26) Every 40-minute treatment session consisted in isotonic and isometric exercises for the major muscles of the limbs and trunk including cardiovascular warm-up exercises (5 minutes), muscle stretching exercises (10 minutes), muscle stretching exercises for functional purposes (10 minutes), balance training exercises (10 minutes), relaxation exercises (5 minutes). This protocol was designed in accordance with PD rehabilitation guidelines and evidences in the literature.
The sessions were conducted on a treadmill with partial weight unload. Specifically, the patient performed 10-minute treadmill walk with a support corresponding to 20% of his/her own weight, followed by a 5-minute rest and a second 10-minute session on the treadmill with a support corresponding to 10% of his/her own weight. In the initial treadmill session, the starting speed of the treadmill was set to 0.5 km/h, subsequent increments of 0.5 km/h per minute were added to reach the maximum speed that was comfortably tolerated by the patient. This latter was used for the entire training period.
All patients were examined by a neurologist with expertise in Movement Disorders at the beginning of hospitalization (T0) and at the end of the neurorehabilitation period (+4 weeks, T1). The clinical assessment involved a complete neurological examination and administration of the following clinical scales, validated for the assessment of the damage/disability:
for the assessment of PD severity: the Unified Parkinson's Disease Rating Scale, part III (UPDRS-III);
for the assessment of functional independence: the Functional Independence Measure (FIM).
The instrumental assessment of gait was conducted at T0 and T1 by an experienced laboratory Technician using an Optokinetic Gait Analysis System associated to the software Myolab Clinic (ELITE, BTS Engineering Milan), composed of six infrared cameras, with a sampling rate of 100 Hz. According to the Davis protocol, twenty-one spherical reflective markers (15mm in diameter) were applied along the body. Synchronized data acquisition and data processing were performed by analyzer software (BTS, Milan, Italy). In order to perform kinematic analysis of gait, patients were instructed to walk at their preferred speed along a 10-meter walkway with the initial step on the side of disease onset. For each session, the investigators acquired at least three performances and calculated the mean. In order to obtain the best individual performance, all recordings were conducted in the ON phase. The sessions were recorded at 5-min intervals to allow complete recovery from fatigue.
