ABSTRACT

A controlled, single blinded experimental study was conducted to determine the effects of passive joint mobilization on pain and stairs ascending-descending time in subjects with knee osteoarthritis (OA knee). A total of 22 subjects aged 40 and above with mild and moderate OA knee were assigned to either passive knee mobilization plus conventional physiotherapy (experimental group) or conventional physiotherapy alone (control group). Both groups received 2 therapy sessions per week, for 4 weeks. A blinded assessor measured pain with Visual analogue scale and stairs ascending-descending time with Aggregated Locomotor Function test, at baseline and at week 4. There was a significant reduction in pain among subjects in the experimental group (18.07 mm, t = 3.48, p = 0.01) compared to the control group (6.66 mm, t = 0.44, p = 0.67). Non-significant clinical difference was found in stairs ascending-descending time between the two groups (i.e. 6.25s in the experimental group versus 6.78 s in the control group, F(1,10) = 0.70, p = 0.42). No significant correlation was found between pain score and stairs ascending-descending time, r = 0.34, p = 0.16. The addition of passive joint mobilization to conventional physiotherapy reduced pain but not stairs ascending-descending time among subjects with knee osteoarthritis.

ABSTRAK

Satu kajian terkawal rabun sebelah telah dijalankan bagi menentukan kesan mobilisasi pasif sendi terhadap kesakitan dan masa naik-turun tangga di kalangan pesakit artritis lutut. Sejumlah 22 subjek berumur 40 tahun ke atas yang menghidapi artritis ringan dan sederhana dirawak bagi menerima rawatan mobilisasi pasif sendi yang digabung dengan fisioterapi konvensional (kumpulan kajian) atau fisioterapi konvensional sahaja (kumpulan kawalan). Kedua-dua kumpulan menerima 2 sesi rawatan seminggu, selama 4 minggu. Seorang penilai rabun mengukur tahap kesakitan menggunakan skala analog visual dan masa naik-turun tangga menggunakan ujian Aggregated Locomotor Function, di awal kajian dan pada minggu ke-4. Tahap kesakitan berkurangan secara signifikan di kalangan subjek kumpulan kajian (18.07 mm, t = 3.48, p = 0.01) berbanding kumpulan kawalan (6.66 mm, t = 0.44, p = 0.67). Tiada perbezaan klinikal yang tekal semasa naik-turun tangga di antara kedua-dua kumpulan (iaitu 6.25 s bagi kumpulan kajian berbanding 6.78 s bagi kumpulan kawalan, F(1,10) = 0.70, p = 0.42). Tiada hubungan yang bererti ditemui di antara skor kesakitan dengan masa naik-turun tangga, r = 0.34, p = 0.16. Mobilisasi pasif sendi, apabila digabung dengan fisioterapi konvensional mengurangkan kesakitan tetapi tidak tempoh naik-turun tangga di kalangan pesakit osteoartritis lutut.
