Dry Needling for Hamstring Flexibility: A Single-Blind Randomized Controlled Trial.

Context: Hamstring muscle tightness is one of the most common problems in athletic and healthy people. Dry needling (DN) was found to be an effective approach for improving muscle flexibility, but there is no study to compare this approach with static stretching (SS) as a common technique for the increase of muscle length.

Objective: To compare the immediate effects of DN and SS on hamstring flexibility in healthy subjects with hamstring tightness.

The MedRisk instrument for measuring patient satisfaction with physical therapy care: A validation of the Persian-language version.

: Valid and reliable tools are required to measure patient satisfaction with physical therapy care. The aim of this study was to translate the MedRisk instrument for measuring patient satisfaction with physical therapy care (MRPS) into Persian language and to evaluate its measurement properties.: A cross-sectional and prospective validation study design was adopted.

Responsiveness and longitudinal validity of the Persian version of COMI to physiotherapy in patients with non-specific chronic low back pain.

Background and aims The Core Outcome Measures Index (COMI) is a short, self-reported questionnaire for assessing important outcomes in patients with low back pain (LBP). The present study was conducted to explore the responsiveness and longitudinal validity of the Persian COMI (COMI-P) in patients with non-specific chronic LBP. Methods In this prospective cohort study of patients with non-specific chronic LBP receiving physiotherapy, patients completed a booklet containing the COMI-P, Persian Functional Rating Index (FRI-P), and a visual analogue scale (VAS) for pain before and after the end of ten-sessions of physiotherapy.

Immediate Effects of Dry Needling as a Novel Strategy for Hamstring Flexibility: A Single-Blinded Clinical Pilot Study.

Context: There are numerous studies on the benefits of dry needling (DN) for pain relief. No studies exist examining the effects of DN on hamstring flexibility.

Objective: To determine the immediate effects of DN on hamstring flexibility in healthy subjects with shortened hamstrings.

Responsiveness of Minimal Clinically Important Change for the Persian Functional Rating Index in Patients with Chronic Low Back Pain.

Study Design: A prospective, within-group cohort study of 46 patients with chronic low-back pain (CLBP).

Purpose: To assess the responsiveness of the Persian Functional Rating Index (PFRI) and to determine the minimal clinically important change (MCIC) of the PFRI in a cohort of patients with CLBP.

Overview Of Literature: The FRI is an instrument for assessing pain and disability in patients with low-back pain.
