About this study

Study participants will undergo consent and history process. Subjects must meet inclusion and exclusion criteria prior to consent. Once consent is obtained, each subject will undergo instruction and training expectations of each swing phase. Once an adequate determination of proficiency has been met, each subject will undergo EMG and MOTUS sleeve placement on each upper extremity:

Forearm flexors
Forearm extensors
Medial epicondyle
Lateral epicondyle
Posterior rotator cuff musculature

Once participants have undergone appropriate calibration processes, they will perform listed swing progressions in a randomized order:

A. Dry swings - reduced weight (wiffleball) bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) B. Dry swings - normal weight bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) C. Tee hitting - normal weight bat - middle strike zone level - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) D. Soft toss - underhand toss from assistant - middle strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) E. Simulated hitting - pitching machine - randomized strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort)

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Participants must be healthy volunteers who accept all provisions of the study and agree to complete the program in its entirety. Participants should have their own bat and relative experience of at least 2 years of hitting a baseball. Ages accepted will be 16-40.

Exclusion criteria

Previous history of upper extremity injury
Current painful dysfunction resulting in exercise or participation limitation
Any health-related exercise limitation as ordered by physician
Ages outside of 16-40
Inability to access clinic and equipment
Inexperience with baseball hitting or inability to follow instructions from study staff.

Treatment and study plan

Motion capture participant

Behavioral

Once participants have undergone appropriate calibration processes, they will perform listed swing progressions:

15 dry swings with a wiffle bat at low, medium and high effort
15 dry swings with a weighted bat at low, medium and high effort
15 swings off of a tee at low, medium and high effort
15 swings at an underhand toss at low, medium and high effort
15 swings from a pitching machine at low, medium and high effort

Primary outcomes

Force on the elbow

Time frame: January 21 - 27, 2020

Medial force (Newtons) across the elbow, normalized to the subject's body mass (kg), was calculated (N/kg).
