Does the Addition of Manual Therapy Techniques Increase Gastrocnemius/Soleus Length More Than Stretching Alone?
Study Details
Study Description
Brief Summary
This study will examine the short term effects of adding manual therapy techniques to static stretching in Dorsiflexion (DF) Range of Motion (ROM). The investigators will be studying 2 forms of manual therapy, a rear-foot thrust joint mobilization (TJM), and Instrument assisted soft tissue mobilization (IASTM). By comparing 3 groups: TJM+static stretching versus IASTM + static stretching versus static stretching alone the investigators wish to see if there are any short term benefits in DF ROM by adding either of these interventions to static stretching.
The manual therapy treatment will occur over 2 sessions and DF ROM measurements will be taken 4 times over a 2 week period.
The population that the investigators wish to examine are subjects with healthy feet and ankles, but with limited DF ROM.
The primary objective of this study is to see if subjects with decreased dorsiflexion motion will experience greater increases in dorsiflexion motion with the addition of manual therapy of static stretching alone.
Our hypothesis is subjects who receive manual therapy therapy and static stretching will experience a significant increase in DF ROM as compared to subjects who receive static stretching alone. More specifically subjects who are treated with the IASTM will experience greater results than subjects who are treated with the rear-foot thrust mobilization.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Instrument Assisted Soft Tissue Mobilization Subjects randomized into this treatment arm will receive Instrument Assisted Soft Tissue Mobilization to the Gastrocnemius/Soleus complex, as well as a standard stretching/ROM protocol |
Procedure: Instrument Assisted Soft Tissue Mobilization
IASTM treatment: will be performed with the sound assisted soft tissue mobilization tool #5. Patient will be placed in the prone position with the ankle in a relaxed position. The treating therapist will perform 10 scanning strokes in the caudal, cephalic, medial, lateral directions for a total of 40 strokes over the Gastrocnemius/Soleus complex. The therapist can then perform more concentrated strokes in areas noted by the therapist as tight, with a maximum treatment time of 5 minutes.
Other Names:
Other: Static stretching/ROM exercises
Gastrocnemius stretch at wall 3 sets of 30 second holds. Soleus stretch at wall 3 sets of 30 second holds. Standing bilateral dorsiflexion on step x30 with full ROM. Standing bilateral plantar flexion on step x30 with full ROM.

| Experimental: Rearfoot joint mobilization Subjects randomized into this treatment arm will receive a rear-foot joint mobilization as well as a standard stretching/ROM protocol |
Procedure: Rearfoot joint mobilization
A high velocity-low amplitude distractive thrust is directed at the talocrural joint. The procedure is performed with the patient in the supine position. The therapist interlaces hands over the dorsum of the foot with 5th digit placed on talus. The therapist slightly pronates and dorsiflexes the foot. Tension is taken up in a caudal direction until the soft tissue barrier is engaged. A distractive thrust is then applied. This is performed up to 2 times. If the therapist notes a cavitation, the patient is progressed to ROM exercises. If there is no cavitation is noted by the therapist the thrust mobilization is reapplied.
Other Names:
Other: Static stretching/ROM exercises
Gastrocnemius stretch at wall 3 sets of 30 second holds. Soleus stretch at wall 3 sets of 30 second holds. Standing bilateral dorsiflexion on step x30 with full ROM. Standing bilateral plantar flexion on step x30 with full ROM.

| Active Comparator: Static stretching/ROM exercises This is the control group consisting of Static stretching/ROM exercises. No manual intervention is performed with the group. The subjects will perform the standard stretching and ROM protocol |
Other: Static stretching/ROM exercises
Gastrocnemius stretch at wall 3 sets of 30 second holds. Soleus stretch at wall 3 sets of 30 second holds. Standing bilateral dorsiflexion on step x30 with full ROM. Standing bilateral plantar flexion on step x30 with full ROM.

Outcome Measures
Primary Outcome Measures
- Change in Weight bearing dorsiflexion Range of Motion [Immediately prior to treatment, Immediately following treatment (same day), 2 day follow up visit,and at 2 weeks (12-16 days after initial session)]
Subjects will perform 3 practice range of motion (ROM) before the first measurement is taken. Subjects will then be measured for Dorsiflexion range of motion with knee in full extension and then with knee flexed 3 times each. With each measurement subjects will be instructed to bend the ankle forward as far as possible without their heel leaving the ground. The average value for these 3 measurements will be calculated and that will be the subjects DF ROM measurement. The change in ROM at each measurement will be the outcome we are measuring
Eligibility Criteria
Criteria
Inclusion Criteria:
healthy feet and ankles must have limited dorsiflexion ROM. Limited dorsiflexion will be judged by patient having <12 degrees of DF PROM with knee extended, or <50 degrees of weight bearing DF ROM with the knee flexed.
Exclusion Criteria:
-
inability to fully weight bear through their lower extremities
-
have <0-90 degrees of ROM in their knees
-
inability to follow directions
-
presence of a Lower Extremity fracture
-
pregnant or nursing
