Details and patient eligibility

About

This pilot study intends to evaluate whether stroke patients can complete ballistic strength exercises for thirty minutes, three times per week over a six week training period in addition to their existing rehabilitation program.

It will evaluate whether using ballistic training principles, is superior in improving mobility compared with usual care exercises to improve mobility and leg strength in stroke patients.

In this study there will be 15 participants per group, a total of 30 participants. The control group will receive usual care consistent with existing rehabilitation practice and literature. The experimental group will perform task specific strength training in a ballistic fashion.

Full description

Research Aims:

To establish the feasibility of ballistic strength training in stroke and
To evaluate the effects of ballistic strength training exercises on mobility outcomes, strength and quality of life when compared with usual care.

Methods:

This wil be a prospective, randomized, controlled, assessor-blinded pilot study. It will be conducted 3 x per week for 6 weeks (i.e. a total of 18 sessions lasting 30 minutes).

Primary outcome measure: Feasibility

Recruitment
Retention/Attrition
Clinical Feasibility
Safety

Secondary outcome measures - measured at baseline and completion

Ten metre walk test (10MWT) comfortable pace
10MWT maximum safe pace
High level mobility assessment tool (HiMAT): Only in participants where 10MWT is <12.5s at baseline
Timed up and go test (TUG)
Functional Ambulation Category (FAC)
Health Related Quality of Life (HRQoL) via AQoL-4D

Description of intervention:

Control Group:

The control group will complete a suite of exercises based upon existing rehabilitation practices that aim to improve mobility after stroke. The supervising physiotherapist will select and progress the exercises, recording the performance of exercises in an exercise log and detailing incidence of adverse events. Exercise selection will include: gait retraining, cardiovascular fitness, lower limb strengthening, static and dynamic balance

Experimental group:

The experimental group will complete jump squats on the leg sled, single leg toe push offs (or bilateral where unable to complete single), alternating legs (i.e. bounding), mini tramp jumping, progressing to jogging, quick hip flexion and bounding on land.

Inclusion criteria

Inpatient at Caulfield Hospital Neurological Rehabilitation Unit at the time of recruitment
Diagnosis of first stroke
Presence of lower limb weakness determined by >10% difference in knee extensor strength between sides
Functional Ambulation Category (FAC) > 3
Can walk a minimal distance of 14 metres (to allow measurement on a 10metre walk test (10MWT)

Participants who meet all the inclusion criteria except for their FAC score will have their FAC score re-measured on a weekly basis until they reach a score of greater than or equal to 3, at which point they become eligible and will be approached for recruitment.

Exclusion criteria

Unable to provide informed consent (determined by consultation with rehabilitation consultant and the team neuropsychologist)
Other diagnosed central nervous system disorder affecting mobility
Active oncological diagnosis
Unstable medication condition such as unstable diabetes or unstable cardiac condition that would prevent participation in cardiovascular activity
Recent orthopaedic trauma and/or osteoarthritis that would limit participation in physical exercise
Not willing to continue to attend the program if they discharge home before the end of the six week program
