Clinical Trial Summary

Parkinson disease is a progressive neurologic disorder characterized by motor impairments which alter the walking capacity, and lead to reduced walking speed, decreased stride length and increased double support time. Physical therapy interventions are an important part of the non-pharmacological treatment for Parkinson disease. The purpose of this study was to assess whether there is a different outcome regarding improvement of walking speed, when applying a physical therapy program in an individual or in a group manner.

A prospective, observational, cohort type study on 60 patients with Parkinson disease was carried out between November 2014 - July 2017, in the Clinical Rehabilitation Hospital in Cluj-Napoca, Cluj county, Romania. Patients were randomly divided into 2 groups, and were prescribed either individual (1 patient and 1 physical therapist) or group physical therapy (6 patients and 1 physical therapist). Treatment protocol included 10 sessions of physical therapy, in the same room setting and performed the same routine of exercises, except for the 3 breaks during the sessions in the group therapy for informal socialization. Walking speed was measured by two validated instruments, the 6-minute walk test and the 10-meter walk test, before and after treatment.

Patients with PD could benefit more from a group physical therapy program, as gait speed increased significantly. The group approach facilitates interactions and is cost-effective, as it requires only one therapist and more patients.

Description:

The current study was carried out during November 2014 - July 2017, in the Clinical Rehabilitation Hospital in Cluj-Napoca, Cluj county, Romania. A total of 60 subjects diagnosed with typical, idiopathic PD participated in this study.

All patients met the following inclusion criteria: (1) stable medication usage; (2) Hoehn and Yahr stage 2, 3 or 4; (3) ability to walk independently or by using an assistive walking device; (4) age 50 to 70 years; (5) no severe cognitive impairments (Mini-Mental State Examination - MMSE score, ≥24); (6) no other severe neurologic, cardiopulmonary or orthopedic disorders; and (7) not having participated in a PT or rehabilitation program in the previous 2 months.

The patients were randomly divided into 2 treatment groups: group physical therapy -GPT (n=30) and individual physical therapy - IPT (n=30).

Treatment protocol for each group included 10 sessions of physical therapy, each 1.5 hour long, on a daily basis for 2 weeks. All treatment sessions occurred at the same time of day throughout the study, in the morning, 60-90 minutes after intake of pharmaceutical treatment for PD. For the GPT, there were groups of 6 patients, supervised by 1 physical therapist. The group sizes were kept small to promote efficiency and motivation. The patients undertaking IPT were alone with the physical therapist during the sessions. Both groups had their encounters in the same physical therapy room setting.

The rehabilitation protocol for the IPT consisted of cardiovascular warm-up activities, stretching exercises, strengthening exercises, functional, gait and balance training, recreational games and ended with relaxation exercises. In addition, the GPT protocol followed the exact same pattern, except for 5-10 minute breaks for informal socialization between participants, at the beginning of the session, mid-session and at the end of the session.

Also, both groups had access to external cues, which were applied during a variety of tasks and environmental situations, like gait initiation and termination, heel strike and push-off, sideways and backwards stepping, walking while dual tasking, and walking over various surfaces and long distances. There is evidence in the literature to support each of the components contained in the intervention.19-25 In order to facilitate initiation and speed of movement, most activities employed visual and auditory cues as triggers. Visual cues were looking at and follow the therapist's movements in the IPT group or the other group member's movements in the GPT group. A mirror was also used. Auditory cues were music with regular rhythm, and verbal suggestions and reinforcement from the therapist, in the IPT group or the therapist and other participants, in the GPT group.

All patients were evaluated at the beginning and at the end of the physical therapy program. The evaluation included the 6-minute walking test and the 10-meter walking test. Gait speed for each participant was calculated as the ratio between the walked distance and the time unit, and it was measured in meters/seconds.

For each subject, all assessment sessions were performed in the morning, by the same person and all tests were performed in the same order, to control for variations in performance because of medication cycle. All assessments were conducted in the "on" state for the subjects experiencing motor fluctuations.
