Outcome Measures

Primary Outcomes (4)

  • Change in Strength

    Measurement of peak torque (Nm/kg) for Shoulder Adduction. Measurement was done using the Biodex System.

    Baseline and 12 weeks

  • Change in Upper Extremity Pain

    Score generated by the Numerical Rating Scale for shoulder pain. Participants self report upper extremity pain over the last 24 hours with scores on a 0 to 10 scale. Higher scores represent higher levels of pain.

    Baseline and 12 weeks

  • Change in General Health Measures

    Score generated by the Short Form 36 walk-wheel. Participants self report on health questions within 8 domains each of which are scored from 0 to 100. The scores from each of the subscales are then averaged together to obtain an overall total score. A score of 0 represents the worst possible health state and a score of 100 represents the best possible health state.

    Baseline and 12 weeks

  • Changes in Functional Shoulder Pain

    Score generated by the Wheelchair Users Shoulder Pain Index. Participants self report shoulder pain over the past week while performing activities of daily living. Scores range from 1 to 150 where higher scores represent higher levels of pain.

    Baseline and 12 weeks

Secondary Outcomes (6)

  • Change in Peak Speed

    Baseline and 12 weeks

  • Change in Acceleration

    Baseline and 12 weeks

  • Change in Peak Force

    Baseline and 12 weeks

  • Change in Mechanical Effective Force

    Baseline and 12 weeks

  • Wheelchair Transfer Ability

Study Arms (2)

Resistance Training - Vibrating Dumbbell

EXPERIMENTAL

Study participants who are randomized into the vibration exercise group will complete an in-home exercise program using a vibrating dumbbell.

Device: Vibrating Dumbbell

Resistance Training - Standard Dumbbell

ACTIVE COMPARATOR

Study participants who are randomized into the control exercise group will complete an in-home exercise program using standard dumbbells.

Device: Standard Dumbbell

Interventions

Supervised training sessions will occur optimally, 3 times per week for a total of 12 consecutive weeks. The sessions will involve nine exercises specifically designed to improve upper limb muscle function. The beginning training intensity for each participant will be based on their one rep max for each exercise, which is determined during baseline laboratory testing in accordance with standard procedures. Training intensity will be adjusted progressively, first by increasing the frequency of the vibration (max. 40 Hz) then by the addition of more weight, based on weekly assessments and consultation with the senior investigators.

Training intensity will be adjusted progressively by the addition of more weight, based on weekly assessments and consultation with the senior investigators. To obtain as much data as possible on resistance training with vibration within study timeline, a modification was recently approved by the Institutional Review Board (IRB) to cease enrolling subjects into standard dumbbell training.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • have a neurological impairment secondary to spinal cord injury (SCI) or disease at T2 or lower
