Brief Summary
This prospective, single-blind, randomized controlled trial investigates whether the addition of spinal mobilization to a structured home exercise program improves pain, flexibility, lower-extremity strength, dynamic balance, and jump performance in recreational tennis players (aged 18-45 years; BMI 18-30 kg/m²) with non-radiating mechanical low back pain. Participants were allocated to two parallel groups: a Control Group performing a 21-session home exercise program for 3 weeks, and an Experimental Group performing the same program plus four physiotherapist-administered spinal mobilization sessions (one at baseline and one weekly for 3 weeks). Outcomes were the Visual Analog Scale (VAS) for pain during physical activity, at rest, and at night; the Y-Balance Test; the Vertical Jump Test; the Sit-and-Reach Test; and isometric strength measured with a back-chest-leg dynamometer.

Outcome Measures
Primary Outcomes (1)
Visual Analog Scale (VAS) for pain during physical activity (cm
Self-reported pain intensity during physical activity recorded on a 10-cm horizontal Visual Analog Scale anchored from 0 ("no pain") to 10 ("worst imaginable pain"). Lower values indicate less pain. Safety Issue: No.
Baseline to Week 3

Study Arms (2)
Control Group (CG):Home Exercise Program Only
ACTIVE COMPARATORStructured home-based exercise program performed daily for 3 weeks (21 sessions). The program included posterior pelvic tilt, double knee-to-chest erector spinae stretching, combined hamstring and lumbar extensor stretching (long-sit toe touch), piriformis stretching, and static hamstring stretching. Adherence was supported by written instructions, visual materials, and weekly telephone follow-up.
Experimental Group (EG): Spinal Mobilization Plus Home Exercise Program
EXPERIMENTALThe identical home exercise program (21 sessions over 3 weeks) plus four sessions of supervised spinal mobilization administered by a physiotherapist - one at baseline and one per week for 3 weeks - using Maitland-graded techniques (Levels I-V; end-range not forced).
Interventions
21 daily sessions over 3 weeks; 5 repetitions per exercise (30-second holds for stretches; 10-second hold for posterior pelvic tilt); supported by written instructions, visual materials, and weekly telephone follow-up.
Four supervised sessions over 3 weeks (one at baseline and weekly thereafter). Techniques included thoracic posteroanterior mobilization (T5-T12), rotational thoracic mobilization ("butterfly/screw"), sacroiliac mobilization, side-lying lumbar mobilization, and anteroposterior lumbar mobilization. Each technique was applied as five sets of one-minute oscillations with 20-second rest intervals in the posteroanterior, mediolateral, and transverse planes.
Eligibility Criteria
You may qualify if:
- Adults aged 18-45 years.
- Body mass index (BMI) between 18 and 30 kg/m².
- Mechanical low back pain that decreases in the supine position and increases with activity or in various postures.
- Low back pain of more than one week duration with a baseline intensity greater than 4 on the Visual Analog Scale (VAS) and unrelated to any defined medical condition.
- Playing tennis on a recreational basis at least 2 days per week, totalling at least 2 hours per week.
- Able to communicate in Turkish or English in both written and spoken form.
You may not qualify if:
- Pain in the lower back, hip, or groin lasting longer than 6 months.
- Pain accompanied by a sensory deficit.
- Pain radiating to the hip or lower extremity.
- History of long-term steroid use.
- Regular medication use.
- History of injury or surgery resulting in residual deficits.
- Previous interventional treatment to the lumbar region.
- Pregnancy or suspected pregnancy.
- Termination Criteria During Study:
- Onset of an acute illness requiring treatment (e.g., influenza, pneumonia).
- Use of analgesic or sedative medication.
- An increase in VAS pain score greater than 3 points during exercise or treatment.
- Failure to perform the home exercise programme on three consecutive days.
- Missed manual therapy session.
