About this trial

This study explores the acute effects of neurodynamics, an intervention commonly used by physical therapist to improve nerve mobility and decrease pain, on the strength and muscular endurance in the athletic population. This study aims to find if these interventions can maintain or promote strength and endurance in the hamstrings. The studies results will help physical therapist better prescribe exercise and hands-on treatment for hamstring and sciatic nerve related conditions and injuries.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Participants must be between 18 and 30 years of age.

Must be able to read, understand, and provide informed consent, in English.

Must be currently participating in an organized sport (e.g. collegiate, club, or competitive recreational level) or engaging in structured resistance training and athletic conditioning for recreational sports events (e.g 5k, marathon, Crossfit, Hyrox, etc).

Medically stable with no known contraindications to physical exertion.

Disqualifiers

Individuals younger than 18 or older than 30.

Acute lower extremity injury in the last 12 weeks.

Lower extremity surgery within the last 12 months.

Pain in either lower extremity that would limit maximal physical exertion.

Trial design

Design model

Single group

Treatments tested in this trial

Sciatic Slider
Other intervention
Mobility of a nerve, by placing tension on one end of the nerve and slacking (removing) tension off the other side of the nerve, through a full range of motion.
Sciatic Tensioner
Other intervention
Loading the nerve, by placing tension on both ends of the nerve, isometrically at end range of motion.
Mechanically loaded neurodynamic sciatic floss
Other intervention
Placing tension on one end of the nerve while taking the tension off the other end, under external load of an elastic resistance band.
Elastic Resistance Band
Device
Elastic resistance band was used to provide submaximal resistance during the mechanically loaded neurodynamic intervention.

Treatment groups
